Description

The present invention relates to a preparation assistance system and a preparation assistance program that assist in part or all of the preparation work of mixing a drug and a liquid and placing the mixture in a dosing container based on preparation data.

As a related technique, a preparation support system (mixing support device) that supports the preparation (mixing) of medicines such as anticancer drugs is known (see, for example, Patent Document 1). The preparation support system according to the related technique is used to improve the efficiency of preparation work performed by a user (operator) such as a doctor or pharmacist. The preparation work is a task of injecting a medicine such as an anticancer drug indicated in the preparation data from one or more medicine containers containing a predetermined amount of the medicine into an infusion container. Specifically, in the preparation work, the user performs the task of aspirating a dissolving liquid such as saline from the infusion container with a syringe, injecting it into the medicine container containing the medicine to dissolve the medicine, and aspirating the dissolved medicine liquid with a syringe and injecting it into the infusion container.

The preparation assistance system sequentially displays the work steps included in the preparation work on the operation display unit based on the preparation data that is the subject of the preparation work. This allows the user to proceed with the work steps in order according to the display. Here, the prepared medicine (medicinal liquid) is administered to the patient using an administration container that contains the medicine. Therefore, when the medicine prepared in the preparation work is injected into an infusion container, the infusion container is used as the administration container.

JP 2020-69268 A

In the preparation assistance system, when there are multiple containers (such as infusion bags) that contain the liquid included in the preparation data, which of the multiple containers is to be the administration container is determined, for example, by the order of the data (liquid, medicine) in the preparation data. Therefore, depending on the content of the preparation data, the container actually used to administer the medicine may not be specified as the administration container, and for example, instructions may be given to inject the dissolved medicine into an infusion container that is not an administration container, which may result in insufficient efficiency in the preparation work.

The object of the present invention is to provide a preparation assistance system and a preparation assistance program that can facilitate further efficiency in preparation work.

A preparation assistance system according to one aspect of the present invention includes an assistance processing unit and a specific processing unit. The assistance processing unit assists in a part or all of the preparation work of storing a mixture obtained by mixing a drug and a liquid in a dispensing container based on preparation data. The specific processing unit identifies a container to be used as the dispensing container from among a plurality of containers that store the liquid indicated in the preparation data, based on container attribute information related to the container.

A preparation support system according to another aspect of the present invention includes a support processing unit and a recording processing unit. The support processing unit supports a part or all of the preparation work of mixing a drug and a liquid based on preparation data and storing the mixture in a dispensing container. When the preparation work includes a total amount discarding process of discarding the entire amount of remaining liquid in any one of the containers that contains the liquid, the recording processing unit records empty container information indicating the state of the one of the containers after the total amount discarding process.

A preparation support system according to another aspect of the present invention includes a support processing unit and a judgment processing unit. The support processing unit supports a part or all of a preparation operation of storing a mixture obtained by mixing a drug and a liquid in a dispensing container based on preparation data. When the preparation operation includes a sampling step of sampling the liquid from a container in which the liquid is stored, the judgment processing unit judges whether the amount of the liquid sampled in the sampling step is appropriate. When a judgment condition is satisfied including that the sampling step is a total amount discarding step of discarding the entire amount of remaining liquid from the container, the judgment processing unit does not execute at least one of a process related to the judgment of the appropriateness of the sampled amount and a process of outputting a judgment result of the appropriateness of the sampled amount.

A preparation support system according to another aspect of the present invention includes a support processing unit and a judgment processing unit. The support processing unit supports a part or all of the preparation work of storing a mixture obtained by mixing a drug and a liquid in a dispensing container based on preparation data. The judgment processing unit judges whether or not the preparation work includes a total amount discarding step of discarding the entire amount of the remaining liquid in any one of the containers in which the liquid is stored. When it is judged that the total amount discarding step is included in the preparation work, the support processing unit issues a total amount discarding instruction to instruct the total discarding of the remaining liquid stored in the one container in a manner that is distinguishable from a normal instruction that instructs the amount of the liquid stored in the one container to be extracted.

A preparation assistance program according to another aspect of the present invention is a program for causing one or more processors to execute the steps of: assisting in a part or all of the preparation work of placing a mixture obtained by mixing a drug and a liquid in a dispensing container based on preparation data; and identifying a container to be used as the dispensing container from among a plurality of containers that contain the liquid indicated in the preparation data, based on container attribute information related to the container.

The present invention provides a preparation assistance system and a preparation assistance program that can facilitate further efficiency improvements in preparation work.

The following describes an embodiment of the present invention with reference to the attached drawings to facilitate understanding of the present invention. Note that the following embodiment is an example of the present invention and is not intended to limit the technical scope of the present invention. In addition, the configurations and processing functions described in the following embodiments can be selected and combined in any combination.

[Preparation support system 1]
1, a preparation assistance system 1 according to an embodiment of the present invention includes a control unit 11, an operation display unit 12, a first reading unit 13, a printer 14, an operation input unit 15, an imaging unit 16, a communication I/F (interface) 17, a second reading unit 21, and a weighing unit 22. In this embodiment, the preparation assistance system 1 is used to improve the efficiency of a drug preparation operation performed by a user (operator) such as a doctor or a pharmacist, and assists in a part or all of the preparation operation.

The users of the preparation assistance system 1 are, for example, pharmacists, doctors, nurses, medical staff, or facility managers at medical institutions such as hospitals, nursing homes, or pharmacies. In this embodiment, as an example, the preparation assistance system 1 is used in a hospital, and the pharmacists at the hospital (hospital pharmacists) are the users of the preparation assistance system 1.

In addition, in the field of medicines (pharmaceuticals), "preparation" in this disclosure means mixing multiple medicines or preparing them in appropriate amounts according to the patient's disease or condition, and includes mixing the medicines with each other, mixing the medicine with a liquid such as an infusion (including an injection), and mixing the liquids with each other. The medicine includes liquid medicines (medicinal liquids) and powder medicines (powders), and if the medicine is a powder, dissolving the powder in the liquid (solubilizing liquid) such as an infusion is also included in mixing the medicine with the liquid. In this embodiment, unless otherwise specified, the preparation work, partly or in whole of which is supported by the preparation support system 1, includes a series of steps of mixing the medicine with the liquid based on preparation data and storing the mixture of the medicine and the liquid (hereinafter referred to as the "prepared medicine") in an administration container.

Here, for example, when a drug (medicinal liquid) is extracted from a drug container with a syringe and injected into the dispensing container containing the liquid, the prepared drug (a mixture of the drug and the liquid) is generated in the dispensing container. In this way, even when the prepared drug is generated in the dispensing container, the prepared drug is ultimately contained in the dispensing container. Therefore, the manner in which the prepared drug is contained in the dispensing container includes not only the manner in which the prepared drug is generated outside the dispensing container and then contained in the dispensing container, but also the manner in which the prepared drug is generated inside the dispensing container and then contained in the dispensing container. As an example, in the preparation work, an injectable drug such as an anticancer drug is prepared.

The preparation assistance system 1 sequentially displays procedures and instructions for each work step included in the preparation work on the operation display unit 12 based on the preparation data. This allows the user to proceed with the preparation work in sequence by following the display on the operation display unit 12.

Specifically, in the preparation work, the user may, for example, use a syringe to aspirate a liquid medicine (medicinal liquid) from a medicine container and inject it into an infusion container such as an infusion bag containing a liquid such as saline. In addition, in the preparation work, the user may, for example, use a syringe to aspirate a liquid such as saline from an infusion container such as an infusion bag and inject it into a medicine container containing a powdered medicine (powdered medicine) to dissolve the powdered medicine, and then aspirate the dissolved medicinal liquid with a syringe and inject it into an infusion container such as an infusion bag. The prepared medicine is administered to a patient using an administration container that contains the prepared medicine. Therefore, when the medicine prepared in the preparation work (the prepared medicine) is injected into an infusion container, the infusion container is used as the administration container.

2, the second reading unit 21 and the weighing unit 22 are disposed in the work chamber 101 of the safety cabinet 100. On the other hand, the control unit 11, the operation display unit 12, the first reading unit 13, the printer 14, the operation input unit 15, the photographing unit 16, and the communication I/F 17 are disposed outside the work chamber 101 of the safety cabinet 100. Note that the arrangement of each part of the preparation assistance system 1 shown here is merely an example and is not limited to this arrangement. For example, the photographing unit 16 may be disposed in the work chamber 101.

The safety cabinet 100 includes a work chamber 101, which is partitioned off by a transparent glass door 102 at the front. The glass door 102 is supported at a position where an opening 103 is formed below, and a user can access the work chamber 101 by inserting their hand through the opening 103. The safety cabinet 100 is also provided with an air purifier 104 having a HEPA filter for purifying the air in the work chamber 101 and discharging it.

3, the user inserts both hands into the work chamber 101 through the open portion 103 and performs the drug preparation work while visually checking the inside of the work chamber 101 through the glass door 102. In the preparation work, the user, for example, uses a syringe 203 to aspirate liquid drug (medicinal liquid) from a drug container 201 in the work chamber 101, and injects it into an infusion container 202, such as an infusion bag, that contains a liquid such as saline.

Specifically, the drug container 201, the infusion container 202, and the like are arranged in the work chamber 101. The drug container 201 contains a predetermined amount of the drug to be prepared in the preparation work, and is composed of containers of various types and sizes (capacities), such as a vial containing a drug solution, a vial containing a powdered drug, or an ampoule containing a drug solution. The infusion container 202 contains a predetermined amount of infusion liquid as the liquid used in the preparation work, and is an example of a "container" that contains the liquid. The liquid contained in the infusion container 202 includes, for example, physiological saline, glucose, or high-calorie infusion. The infusion container 202 is composed of containers of various types and sizes (capacities), such as an infusion bag (soft bag), a plastic bottle, or a vial.

In addition, when preparing non-toxic drugs or infusions, a clean bench or the like may be used in place of the safety cabinet 100 in the preparation assistance system 1.

The second reading unit 21 provided in the work room 101 of the safety cabinet 100 is a code reading device capable of reading code information such as one-dimensional codes or two-dimensional codes. The code information is attached to a container (the drug container 201 or the infusion container 202) in which the drug or liquid used in the preparation work is contained. The two-dimensional code is, for example, a QR code (registered trademark). The code information includes identification information (hereinafter also referred to as "content identification information") for identifying the type of the drug or liquid contained in the drug container 201 or the infusion container 202 to which the code information is attached. Furthermore, the code information includes identification information (hereinafter also referred to as "container identification information") for identifying the drug container 201 or the infusion container 202 to which the code information is attached, that is, the container itself rather than the contents. The code information read by the second reading unit 21 is input to the control unit 11.

The weighing unit 22, which is also provided in the work chamber 101 of the safety cabinet 100, is an electronic balance used for various measurements in the preparation work. The weighing results by the weighing unit 22 are input to the control unit 11 in real time. The weighing unit 22 also inputs stability information indicating whether the weighing results are stable or not to the control unit 11. This allows the control unit 11 to obtain the weighing results by the weighing unit 22 and information such as whether the results are stable or not. The control unit 11 may be configured to actively read out the weighing results by the weighing unit 22 and information such as whether the results are stable or not.

The communication I/F 17 is a communication interface that performs data communication with a higher-level system wirelessly or wired via a communication network such as a LAN (Local Area Network), a WAN (Wide Area Network), the Internet, or an intranet. The communication I/F 17 is configured to be able to perform data communication with not only the higher-level system, but also, for example, the second reading unit 21 and the weighing unit 22 in the workroom 101, and even with an external terminal such as a wearable terminal or a client terminal.

The higher-level system is, for example, an electronic medical record system, an ordering system, or a medical receipt computer processing system. The higher-level system is a system separate from the preparation assistance system 1, and it is sufficient that the higher-level system is capable of linking with the preparation assistance system 1 through communication, and it is not essential that the higher-level system is in a "higher-level" relationship with the preparation assistance system 1. Note that multiple higher-level systems may be provided, and the multiple higher-level systems may include different types of systems.

The control unit 11 is communicably connected to the upper system via the communication I/F 17. The control unit 11 can obtain the preparation data indicating the content of the preparation work performed by the user from the upper system.

For example, the preparation data includes patient information (patient ID, patient name, height, weight, and body surface area, etc.), preparation date, drug information (drug code or drug name, etc.), liquid information (infusion code or infusion name, etc.), dosage, regimen identification information, information about the drug container 201, and information about the infusion container 202. The regimen identification information is information that can identify regimen information, such as a therapy name (regimen name), a therapy ID, or a regimen ID. The preparation data also includes information about the type (ampule containing a drug solution, a vial containing a drug solution, a vial containing powdered medicine, or an infusion bag, etc.) and size (volume) of the drug container 201 or the infusion container 202. Furthermore, the preparation data may include doctor information, preparation content information (syringe 203 used in the preparation work, type and number of needles, etc.), preparation procedure information (work content, solvent, amount of solvent, amount extracted, etc.), administration date, prescription category, medical department, and ward.

The control unit 11 is mainly composed of a computer having one or more CPUs (Central Processing Units) 111, one or more RAMs (Random Access Memories) 112, and one or more storage units 113.

The storage unit 113 includes storage areas such as a data area, a program area, and a master area. The storage unit 113 may include multiple storage media, and the data area, the program area, and the master area may be distributed across the multiple storage media.

The preparation data acquired from the higher-level system is accumulated and stored in the data area. The control unit 11 can also newly register or edit the preparation data in response to user operations. The data area also stores history data indicating the content of the preparation work performed by the user in accordance with the preparation data in association with the preparation data. For example, the history data includes the user of the preparation work, the start time of the work, the end time of the work, and images taken during the preparation work.

The program area stores a control program for causing the control unit 11 to execute the preparation support process (see FIG. 5) described below. The program area also stores application programs such as an operating system (OS) and browser software.

The master area stores various master information such as a drug master, a patient master, a ward master, a doctor master, and a pharmacist master. For example, the drug master includes information such as a drug ID, a drug name, a drug code, a medicine bottle code, a classification (dosage form: powder, tablet, liquid, topical medicine, etc.), a specific gravity, a drug type (ordinary medicine, anticancer drug, poison, narcotic, powerful drug, antipsychotic, therapeutic drug, etc.), a compounding change, an excipient drug, and a caution. Furthermore, the drug master includes information on the type of the drug container 201 or the infusion container 202 (ampule containing a drug solution, vial containing a drug solution, vial containing a powdered drug, or infusion bag, etc.), the amount of the drug or the liquid contained in each container (predetermined amount), the capacity (maximum capacity), and the weight of the container only, as container attribute information described later. The drug ID is an identification code such as a YJ code, a JAN code, or an RSS code.

The various information stored in the storage unit 113 may be pre-stored in the storage unit 113, may be received from outside the preparation assistance system 1 via a telecommunications line, or may be read from a computer-readable recording medium. In other words, the control program, etc. may be provided by being recorded on a non-transitory recording medium.

The operation display unit 12 has a display unit such as a liquid crystal display or an organic EL (Electro-Luminescence) display that displays various information according to control instructions from the control unit 11, and an operation unit that is operated by a user to input various information to the control unit 11. The operation display unit 12 displays at least the procedures and instructions related to each work step included in the preparation work to the user, and is therefore positioned in a position that is easily visible to the user performing the preparation work.

Specifically, the operation section of the operation display unit 12 is a touch panel that accepts touch operations on various operation screens displayed on the display unit.

The first reading unit 13 is a code reading device capable of reading code information such as a one-dimensional code or a two-dimensional code written (printed) on a preparation receipt or the like corresponding to the preparation data. The code information includes identification information (hereinafter also referred to as "data identification information") for identifying the preparation data. The code information read by the first reading unit 13 is input to the control unit 11. Then, the control unit 11 identifies the preparation data to be the target of the current preparation work based on the code information read from the preparation receipt using the first reading unit 13. Specifically, the control unit 11 reads the data identification information from the code information and selects the preparation data corresponding to the data identification information from the data storage unit 111 of the storage unit 113. Note that the control unit 11 may obtain the preparation data from the code information.

The printer 14 is used by the control unit 11 to print various information. For example, it is used to print the preparation receipt corresponding to the preparation data executed by the control unit 11, or to print the history of the preparation work executed according to the preparation data.

The operation input unit 15 is an operation unit for the user to input operations to the control unit 11 while the preparation work is being performed. As shown in FIG. 2, the operation input unit 15 has, as an example, a first foot switch 151, a second foot switch 152, and a third foot switch 153. The first foot switch 151 and the second foot switch 152 are used for selecting an item to be operated, and the third foot switch 153 is used for deciding an item to be operated. Specifically, in this embodiment, a case will be described in which the control unit 11 executes various processes in response to a user operation on the operation display unit 12 or the operation input unit 15. Therefore, in this embodiment, the "operation", "selection", and "input" by the user described below will be described as being performed using the operation display unit 12 or the operation input unit 15.

The photographing unit 16 is realized, for example, by a camera device fixed outside the work room 101. The data of the image photographed by the photographing unit 16 (hereinafter referred to as "image data") is input to the control unit 11 in real time. The photographing unit 16 is arranged facing the inside of the work room 101 so that it can photograph the syringe (syringe barrel) of the injector 203 in the work room 101 handled by the user. The image photographed by the photographing unit 16 is, for example, a full-color still image, but is not limited to this, and may be, for example, a monochrome image or a moving image. In this embodiment, the photographing unit 16 is controlled by the control unit 11, photographs upon receiving a control signal from the control unit 11, and inputs the obtained image data to the control unit 11. Note that the photographing unit 16 may actively photograph and transmit the image data to the control unit 11.

[Control unit 11]
In the preparation assistance system 1 according to the present embodiment, the control unit 11 includes a support processing unit 31, a specific processing unit 32, a possible/not possible determination processing unit 33, a recording processing unit 34, a judgment processing unit 35, a judgment processing unit 36, and a mode switching unit 37, as shown in FIG. 4. Specifically, the control unit 11 executes various processes related to the preparation assistance process described below according to the preparation assistance program, thereby functioning as various processing units such as the support processing unit 31, the specific processing unit 32, and the possible/not possible determination processing unit 33. That is, in the present embodiment, the control unit 11 embodies the main functions of the preparation assistance system 1. In other words, the preparation assistance system 1 according to the present embodiment only needs to include the control unit 11, and the operation display unit 12, the first reading unit 13, the printer 14, the operation input unit 15, the photographing unit 16, the communication I/F 17, the second reading unit 21, and the weighing unit 22 may not be included as components. The control unit 11 may include a plurality of processors, and any of the plurality of processors may function as the various processing units. Furthermore, a part or all of the various processing sections may be configured with electronic circuits.

In another embodiment, some or all of the functions of the control unit 11 may be provided in the higher-level system, the wearable terminal, the client terminal, or the like. For example, some or all of the preparation assistance program may be installed in the wearable terminal, and the terminal control unit of the wearable terminal may acquire necessary information from the control unit 11 as appropriate and execute various processes related to the preparation assistance process. In this case, the wearable terminal embodies the main functions of the preparation assistance system 1. Furthermore, in the preparation assistance system 1, the control unit 11 and the wearable terminal, etc. may cooperate to execute various processes related to the preparation assistance process.

The support processing unit 31 supports all or part of the preparation work of mixing the drug and the liquid and storing the mixture in the administration container based on the preparation data. Specifically, the support processing unit 31 supports all or part of the preparation work by sequentially displaying procedures and instructions for each work step included in the preparation work on the operation display unit 12 based on the preparation data.

In the preparation work, the user selects the necessary work steps from, for example, the prepared drug authentication step, the tare weight step, the liquid extraction step, the liquid measuring step, the liquid photographing step, the dissolving step, the drug extraction step, the drug measuring step, the drug photographing step, and the mixing step, and executes them in sequence.

The drug authentication process is a process for authenticating the drug and the liquid used in the preparation work, and is, for example, a process for reading the identification information of the drug or the liquid using the second reading unit 21. The tare process is a process for pre-weighing only the weight of the equipment used in the preparation work, such as the syringe 203, and is, for example, a process for placing the syringe 203 on the weighing unit 22.

The liquid extraction process is a process of extracting a required amount of liquid such as physiological saline from the infusion container 202 using the syringe 203. The liquid measurement process is a process for measuring the weight of the extracted liquid, and is a process for placing the syringe 203 on the weighing unit 22. In the liquid measurement process, the control unit 11 measures the difference between the weight of the syringe 203 placed on the weighing unit 22 and the weight of the syringe 203 set by the tare as the weight of the extracted liquid. The dissolving process is a process for dissolving the medicine when the medicine is a powder, and is a process for injecting the liquid extracted by the syringe 203 into the medicine container 201 as a dissolving liquid. The liquid photographing process is a process for photographing the syringe 203 from which the liquid has been extracted using the photographing unit 16.

The drug extraction process is a process of extracting a required amount of the drug (medicinal liquid) from the drug container 201 with the syringe 203. The drug weighing process is a process for weighing the weight of the extracted drug, and is a process for placing the syringe 203 on the weighing unit 22. Note that in the drug weighing process as well, the control unit 11 measures the difference between the weight of the syringe 203 placed on the weighing unit 22 and the weight of the syringe 203 set by the tare weight subtraction as the weight of the drug. The drug photographing process is a process for photographing the syringe 203 from which the medical liquid has been extracted with the photographing unit 16.

The mixing step is a step of injecting the dissolved drug (the prepared drug) or the drug (medicinal liquid) in the syringe 203 into the administration container. That is, if the drug is in a powder form (powdered drug), the drug is dissolved in the liquid as the dissolving liquid in a container (e.g., the drug container 201) other than the administration container, and the drug dissolved in the liquid, i.e., the prepared drug, is moved from the other container to the administration container in the mixing step. Also, if the drug is in a liquid form (medicinal liquid), the drug extracted from the drug container 201 by the syringe 203 is injected into the administration container in the mixing step, and the drug and the liquid are mixed in the administration container to produce the prepared drug. Alternatively, even if the drug is in liquid form (medicinal liquid), the drug may be mixed with the liquid in a container (e.g., the infusion container 202) other than the administration container, and the drug mixed with the liquid, i.e., the prepared drug, may be moved from the separate container to the administration container in the mixing step. As a result, in the preparation work, the prepared drug is finally contained in the administration container.

In this embodiment, the support processing unit 31 basically supports all of the steps in the preparation work, from the drug authentication step for authenticating the drug to the mixing step for placing the prepared drug in the administration container, that is, all of the preparation work.

The identification processing unit 32 identifies a container to be used as the administration container from among a plurality of containers based on the container attribute information related to the container. The plurality of containers are containers that contain the liquid indicated in the preparation data. However, the identification processing unit 32 identifies the container to be used as the administration container only on the data, and strictly speaking, identifies the container identification information of the container to be used as the administration container from a plurality of identification information (container identification information) for identifying the container itself. The container identification information is associated with the container attribute information, for example, in the drug master, and the identification processing unit 32 refers to the container attribute information for each of the container identification information in the drug master. This automatically identifies the container to be used as the administration container, making it easier to avoid, for example, a situation in which the prepared drug is injected into the infusion container 202 that is not the administration container. Thus, the preparation support system 1 that makes it easier to further improve the efficiency of the preparation work is realized. Furthermore, the specific processing unit 32 has the advantage that a container that is suitable for use as the administration container can be automatically selected as the administration container, even if there is no external instruction as to which container to use as the administration container.

In this embodiment, as an example, the "container" containing the liquid is the infusion container 202. The infusion containers 202 are all registered in advance, for example, in the medicine master as candidate administration containers that are candidates for the administration container. Therefore, the identification processing unit 32 identifies the infusion container 202 to be used as the administration container from among the multiple infusion containers 202 based on the container attribute information related to the infusion container 202. Specifically, the identification processing unit 32 identifies the infusion container 202 to be used as the administration container from among the multiple infusion containers 202 by comparing the container attribute information for each of the multiple infusion containers 202 with predetermined specific conditions. The container attribute information is information that represents the attributes of the infusion container 202, and includes, for example, information about the infusion container 202, such as the type (plastic bottle, infusion bag, etc.) and capacity (maximum capacity).

Here, the container attribute information includes information regarding the capacity of the container (the infusion container 202). The identification processing unit 32 identifies the container (the infusion container 202) with the largest capacity among the multiple containers (the infusion containers 202) as the administration container. That is, the identification condition includes that the capacity is the largest among the multiple infusion containers 202. Therefore, for example, when the multiple infusion containers 202 used in the preparation work are of the same type, the infusion container 202 with the largest capacity (maximum capacity) among the multiple infusion containers 202 is identified by the identification processing unit 32 as the administration container. This makes it possible to identify the administration container relatively easily by focusing on the capacity of the infusion container 202. Furthermore, the infusion container 202 having a capacity capable of accommodating the amount of the prepared drug (mixture) specified in the preparation data can be set as the administration container.

The infusion container 202 identified as the administration container by the identification processing unit 32 is presented to the user by the support processing unit 31. In other words, the support processing unit 31 presents the container (the infusion container 202) identified as the administration container by the identification processing unit 32 to the user. The form of "presentation" here may include various forms, such as display on the operation display unit 12, print (printed) output by the printer 14, or voice output. In this embodiment, as an example, the support processing unit 31 presents the infusion container 202 identified as the administration container by display on the operation display unit 12 in a form that can be recognized by the user. Specifically, the support processing unit 31 may not only directly indicate the administration container, such as "The administration container is 500 ml of physiological saline solution," but may also indirectly indicate the administration container, such as "Please return the dissolved drug to a container of 500 ml of physiological saline solution." This allows the user to easily understand which container should be used as the administration container when performing the preparation work.

The possibility determination processing unit 33 determines whether or not there is a container among the multiple containers (the infusion container 202) that has a capacity capable of accommodating the prepared drug (mixture) based on the total amount of the prepared drug (mixture). That is, the prepared drug is ultimately accommodated in the infusion container 202 as the administration container, and in some cases, the total amount of the prepared drug may exceed the capacity of the container (the infusion container 202) with the largest capacity among the multiple containers (the infusion container 202). In this case, since there is no infusion container 202 with a capacity capable of accommodating the prepared drug among the multiple infusion containers 202 used in the preparation work, it is necessary to prepare a separate container as the administration container. The possibility determination processing unit 33 can determine whether or not it is necessary to prepare a separate container as the administration container.

In addition, when the possibility judgment processing unit 33 judges that there is no container with a capacity capable of accommodating the mixture among the plurality of containers (the infusion container 202), the support processing unit 31 notifies at least one of the fact (that there is no container with a capacity capable of accommodating the mixture among the plurality of containers) and that a container other than the plurality of containers will be used as the administration container. Here, the support processing unit 31 may not only directly notify the fact that there is no container with a capacity capable of accommodating the mixture among the plurality of containers, but also indirectly notify the fact by, for example, instructing the user to use a container other than the plurality of containers as the administration container. Specifically, the support processing unit 31 may use the judgment result of the possibility judgment processing unit 33 to instruct the user to use another container as the administration container when there is only a container inappropriate as the administration container among the containers (the infusion container 202) that accommodate the liquid indicated in the preparation data. This makes it easier to prevent a situation in which the user forcibly accommodates the prepared medicine in the inappropriate container.

The recording processing unit 34 records empty container information when the preparation work includes a total disposal process. The total disposal process is a process of disposing of the entire amount of the remaining liquid from any one of the containers (the infusion container 202) in which the liquid is contained. The "residual liquid" here refers to the liquid remaining in the container (the infusion container 202) in which the liquid is contained by removing a portion of the liquid from the container. For example, when 400 ml of the liquid is removed from the infusion container 202 containing 500 ml of the liquid, 100 ml of the liquid remains as the residual liquid in the infusion container 202. The empty container information is information indicating the state of the one container after the total disposal process. That is, when the remaining liquid is completely discarded from any one of the infusion containers 202 in the preparation work, the recording processing unit 34 records the empty container information indicating the state of the one container that has become emptied by the total disposal. The empty container information is, for example, an empty container flag indicating that the infusion container 202 is empty, and is recorded by being stored in the memory unit 113. This makes it possible to keep a record of the fact that the entire amount of the remaining liquid has been discarded.

In this embodiment, the empty container information includes at least one of an image and weight information of the one container (the infusion container 202) that was the subject of the total disposal process. Specifically, the recording processing unit 34 includes at least one of image data (image data) obtained by photographing the infusion container 202 with the photographing unit 16 after the total disposal process, and weight data (the weight information) of the infusion container 202 measured by the weighing unit 22. In this way, when the empty container information includes an image or weight information of the infusion container 202, it also serves as proof (evidence) that the total disposal of the remaining liquid has indeed been performed.

The recording processing unit 34 records the empty container information in association with the preparation data so that the empty container information can be presented to the user at least for each of the preparation data. In other words, since the empty container information is recorded in association with the preparation data, the empty container information can be presented to the user for each of the preparation data by reading out the empty container information later based on the preparation data. The read empty container information is presented to the user in various forms, such as display on the operation display unit 12, printed out by the printer 14, or output as audio. This allows the user to check the status of the one container that has been emptied by the total disposal after the preparation work.

The judgment processing unit 35 judges whether the amount of liquid extracted in the extraction process is appropriate when the preparation work includes an extraction process of extracting the liquid from a container (the infusion container 202) in which the liquid is contained. When the judgment conditions are satisfied, the judgment processing unit 35 does not execute at least one of the process related to the judgment of the appropriateness of the extracted amount and the process of outputting the judgment result of the appropriateness of the extracted amount. The judgment conditions include that the extraction process is a total amount disposal process in which the entire amount of the remaining liquid is discarded from the container (the infusion container 202). In other words, when the liquid extraction process of extracting the liquid from the infusion container 202 is performed, the judgment processing unit 35 judges whether the amount of liquid extracted in principle is appropriate and outputs the judgment result of the appropriateness of the extracted amount. On the other hand, if the liquid extraction process is a process for completely discarding the remaining liquid in the infusion container 202 (the complete discard process) and it is determined that the judgment condition is satisfied, the judgment processing unit 35 exceptionally does not execute at least one of the process related to the judgment of the appropriateness of the extracted amount and the process of outputting the judgment result of the appropriateness of the extracted amount. As a result, when the judgment condition is satisfied, at least the judgment result of the appropriateness of the extracted amount of the drug is not output.

Therefore, if at least the liquid extraction process is a normal liquid extraction process in which only a portion of the liquid in the infusion container 202 is extracted, and is not the total amount discarding process, the judgment condition is not satisfied, and the judgment processing unit 35 judges the appropriateness of the extracted amount as a rule, and outputs the judgment result of the appropriateness of the extracted amount. Specifically, the judgment processing unit 35 compares, for example, the weight (measured value) of the liquid measured in the liquid measuring process after the liquid extraction process with an appropriate range based on the weight corresponding to the extracted amount of the liquid in the liquid extraction process, and judges the measured value to be appropriate if it is within the appropriate range, and outputs the judgment result. If the measured value is outside the appropriate range, it judges the measured value to be inappropriate, and outputs the judgment result. In this way, the judgment processing unit 35 judges the appropriateness of the extracted amount of the liquid, for example, by weight inspection.

On the other hand, when the liquid extraction process is the total amount discarding process in which the entire amount of the remaining liquid in the infusion container 202 is extracted and discarded, and the judgment condition is satisfied, the judgment processing unit 35 does not judge the appropriateness of the extracted amount in the first place, or does not output the judgment result of the appropriateness of the extracted amount. Specifically, the judgment processing unit 35 skips, for example, the liquid measuring process after the liquid extraction process. In this way, when the judgment condition is satisfied, the judgment processing unit 35 does not judge the appropriateness of the extracted amount of the liquid, for example, by weight inspection. However, the judgment condition may include, in addition to the liquid extraction process being the total amount discarding process, for example, that the extracted amount is equal to or less than a predetermined amount (for example, the capacity of the syringe 203). In this case, even if the liquid extraction process is the total amount discarding process, if the extracted amount exceeds the predetermined amount, the judgment condition is not satisfied, and the judgment processing unit 35 judges the appropriateness of the extracted amount as a rule, and outputs the judgment result of the appropriateness of the extracted amount.

According to this configuration, in the normal liquid extraction process in which only a portion of the liquid in the infusion container 202 is extracted, the judgment processing unit 35 can judge whether the amount of extraction is appropriate and output the judgment result of the appropriateness of the amount of extraction. In contrast, when the liquid extraction process is the total amount discarding process and the judgment condition is satisfied, the judgment of the appropriateness of the amount of extraction or the output of the judgment result of the appropriateness of the amount of extraction is not performed. As an example, when the remaining liquid in the infusion container 202 is discarded in total in order to use the infusion container 202 as the administration container, the remaining liquid in the infusion container 202 is only discarded, so that the judgment of the appropriateness of the amount of extraction by weight inspection or the like is not required. In such a case where the judgment of the appropriateness of the amount of extraction is not required, the processing by the judgment processing unit 35 is limited, so that the processing load of the control unit 11 can be reduced. Furthermore, the infusion container 202 is generally overfilled, and the amount of liquid actually contained in the infusion container 202 is greater than the amount of liquid registered in the medicine master or the like. Therefore, in the case of the total amount being discarded, the amount of overfilling will be greater than the amount of liquid extracted, and the result of the determination of whether the amount of liquid extracted is appropriate may be inappropriate (an error). With the configuration according to this embodiment, it is possible to avoid an error or the like being notified about the liquid involved in the total amount being discarded, even if the amount of liquid extracted is inappropriate.

The determination processing unit 36 determines whether or not the preparation work includes a total amount discarding process. The total amount discarding process is a process of discarding the entire amount of the remaining liquid from any one of the containers (the infusion container 202) in which the liquid is contained. When it is determined that the total amount discarding process is included in the preparation work, the support processing unit 31 issues a total amount discarding instruction in a manner that can be distinguished from a normal instruction. The total amount discarding instruction is an "instruction" that instructs the disposal of the entire amount of the remaining liquid contained in the one container (the infusion container 202). The normal instruction is an "instruction" that instructs the amount of the liquid contained in the one container (the infusion container 202) to be extracted. In other words, the support processing unit 31 is configured to use two types of instructions, the total amount discarding instruction and the normal instruction, and the total amount discarding instruction and the normal instruction are output in a manner that can be distinguished from each other.

Specifically, when the support processing unit 31 sequentially displays instructions, etc., related to each work process included in the preparation work on the operation display unit 12 based on the preparation data, the support processing unit 31 displays the all-amount disposal instruction and the normal instruction on the operation display unit 12 in a manner that can be distinguished from each other. For example, in the liquid extraction process, if the support processing unit 31 receives the normal instruction, the support processing unit 31 displays the instruction "Please remove the dissolving liquid" on the operation display unit 12 together with an instruction on the amount of the liquid to be extracted, such as "Dose: 32.6 mL". On the other hand, if the all-amount disposal instruction is received, the support processing unit 31 displays an instruction on the operation display unit 12 that is recognizable by the user as an instruction to discard the entire amount, such as "Please discard the entire amount of remaining liquid" or "Please empty the container". Alternatively, in the all-amount disposal instruction, the support processing unit 31 may display, for example, an instruction with the same content as the normal instruction on the operation display unit 12, while displaying a mark indicating all-amount disposal on the operation display unit 12.

The judgment processing unit 36 judges whether the total amount discarding process is included in the preparation work, for example, based on at least the preparation data. In this embodiment, the judgment processing unit 36 judges whether the total amount discarding process is included in the preparation work, for example, based on at least the type of the medicine indicated in the preparation data. That is, for example, when a certain type of the medicine is indicated in the preparation data, the judgment processing unit 36 judges that the liquid extraction process of extracting the liquid from the infusion container 202 based on the preparation data is the total amount discarding process. Note that, for example, when the preparation data includes an instruction (data) indicating total amount discarding, the judgment processing unit 36 may judge that the total amount discarding process is included in the preparation work, based on the preparation data.

The mode switching unit 37 switches the presentation mode of the procedures and instructions, etc., related to each work process included in the preparation work by the support processing unit 31. The presentation modes include a first mode and a second mode, which have different forms even when presenting at least the same information (procedures, instructions, etc.). The mode switching unit 37 switches the presentation mode based on at least user information related to the user. In this embodiment, the support processing unit 31 sequentially displays the procedures and instructions, etc., related to each work process included in the preparation work on the operation display unit 12 based on the preparation data, so that, for example, the form of the screen displayed on the operation display unit 12 differs between the first mode and the second mode. In other words, even when the support processing unit 31 displays procedures and instructions, etc., related to the same work process, the first mode and the second mode are displayed differently.

For example, the first mode and the second mode differ in the level of detail of the procedures and instructions displayed on the operation display unit 12, in other words, the amount of information. In the present embodiment, as an example, the first mode is a simple display mode, and the second mode is a detailed display mode. In the detailed display mode as the second mode, more detailed (i.e., more information) procedures and instructions are displayed on the operation display unit 12 than in the simple display mode as the first mode. The mode switching unit 37 switches the presentation mode between the first mode and the second mode according to, for example, the user's proficiency, skill level, affiliation, position, years of service, or age, thereby enabling support for the preparation work appropriate for the user. For example, the mode switching unit 37 selects the first mode (the simple display mode) for a veteran user whose proficiency is higher than a threshold, and the second mode (the detailed display mode) for a user whose proficiency is equal to or lower than the threshold. This allows for the omission of cumbersome procedures and instructions for experienced users, while providing inexperienced users with thorough support for the preparation process by displaying detailed procedures and instructions.

[Preparation support process]
5 to 7, the preparation assistance process executed mainly by the control unit 11 in the preparation assistance system 1 will be described. However, the preparation assistance process will be described here in the case where the total discarding step is not included in the preparation work.

<Step S11>
In the preparation assistance process, first, in step S11, the control unit 11 accepts a user operation to log in to the preparation assistance system 1 by inputting a user ID and a password, for example, using the operation display unit 12. The user ID is associated with the user information or includes the user information. The control unit 11 authenticates the user ID and password, and when the authentication is successful and it is confirmed that the user is a legitimate user, the control unit 11 proceeds to step S12.

<Step S12>
In step S12, the control unit 11 judges whether the logged-in user is an experienced user. Specifically, the control unit 11 refers to the user information based on the user ID acquired at the time of logging in. The user information includes, for example, the user's proficiency, skill level, affiliation, position, years of service, or age. As an example, the user information includes data that quantifies the user's proficiency, and the control unit 11 judges a user whose proficiency is higher than a threshold to be the experienced user. Here, if it is judged that the user is an experienced user (S12: Yes), the process proceeds to step S13, and if it is judged that the user is not an experienced user because the proficiency is equal to or lower than the threshold (S12: No), the process proceeds to step S14.

<Steps S13 and S14>
In step S13, the mode switching unit 37 of the control unit 11 sets the presentation mode to the first mode (the simple display mode). That is, when the mode switching unit 37 determines that the user is the experienced user based on the user information, the mode switching unit 37 selects the simple display mode in which display of cumbersome procedures and instructions, etc. is omitted. On the other hand, in step S14, the mode switching unit 37 of the control unit 11 sets the presentation mode to the second mode (the detailed display mode). That is, when the mode switching unit 37 determines that the user is not the experienced user based on the user information, the mode switching unit 37 selects the detailed display mode in which more detailed procedures and instructions, etc. are displayed.

In this embodiment, once a user logs in, the presentation mode selected in steps S13 and S14 continues as long as the user remains logged in. In other words, the presentation mode set according to the user is continuously adopted as long as the user does not change. Therefore, the presentation mode selected in steps S13 and S14 continues until the user logs out and logs in again, or until a user (account) change process is performed. However, this configuration is not limited, and for example, the presentation mode may be selected as the initial setting in steps S13 and S14, and the presentation mode may be arbitrarily switched by the user's operation thereafter.

<Step S15>
In step S15, the control unit 11 judges whether the preparation data to be the target of the preparation work has been selected. Specifically, when the identification information (the data identification information) of the preparation data is read by the first reading unit 13, the control unit 11 judges that the preparation data corresponding to the data identification information has been selected. Note that the preparation data may be judged to have been selected when any one of the unprepared preparation data is selected on the preparation data selection screen displayed on the operation display unit 12. Here, if it is judged that the preparation data has been selected (S15: Yes), the process proceeds to step S16, and if the preparation data has not been selected (S15: No), the process waits in step S15. Note that if the preparation data corresponding to the identification information read by the first reading unit 13 is not stored in the storage unit 113 or has already been prepared, an error is notified.

<Step S16>
In step S16, the control unit 11 displays the preparation data selected in step S15 on the operation display unit 12 as the preparation work target. Here, FIG. 6 is a diagram showing an example of a preparation support screen D1 on which the contents of the preparation data are displayed. As shown in FIG. 6, the preparation support screen D1 displays the user name (pharmacist name), inspector name, medical department, ward, start date of administration, doctor name, patient name (patient ID), age, sex, prescription contents, etc. for the preparation data. In addition, the preparation support screen D1 displays the weighing result by the weighing unit 22. The "screen" in this disclosure means a video (image) displayed on the operation display unit 12, etc., and includes images, figures, photographs, text, and videos. Note that in the drawings showing the screens displayed on the operation display unit 12, such as FIG. 6, the dashed lines, leader lines, and reference symbols representing areas are added only for explanation, and are not actually displayed on the operation display unit 12.

<Step S17>
In step S17, the control unit 11 sequentially displays information on each work step included in the preparation work to be performed based on the preparation data on the operation display unit 12. Specifically, the support processing unit 31 of the control unit 11 displays information related to the work steps on the operation display unit 12. Note that, instead of step S17, information on the current work step of the preparation work may be displayed on the operation display unit 12 in each process of steps S19, S21, S23, S25, and S27.

For example, the support processing unit 31 of the control unit 11 sequentially displays information related to various work processes such as the drug authentication process, the tare process, the liquid extraction process, the liquid measuring process, the liquid photographing process, the dissolving process, the drug extraction process, the drug measuring process, the drug photographing process, and the mixing process each time step S17 is executed. The information related to the work processes includes, for example, the content of the work process (such as the type of work process), the amount of work (such as the amount extracted or injected), and the work target (such as identification information of the drug, liquid, or syringe). In the preparation support system 1, the information related to the work processes displayed on the operation display unit 12 differs depending on whether the presentation mode is the simple display mode or the detailed display mode, and the information in the simple display mode is relatively simplified.

Figure 7 is a diagram showing an example of a process screen D11 displayed on the operation display unit 12 in step S17. In the example of Figure 7, the process screen D11 is displayed as a pop-up window superimposed on the preparation support screen D1. However, this is not limited to this example, and the process screen D11 may be displayed as a partial area of the preparation support screen D1, or the screen displayed on the operation display unit 12 may be switched from the preparation support screen D1 to the process screen D11. The process screen D11 includes a work process area A1, a work amount area A2, and a work target area A3 as areas showing information related to each work process in the preparation work. In addition, the process screen D11 further includes an operation area A4 in which currently operable operation items are displayed, and a status area A5 in which the title of the content of the work process displayed on the process screen D11 is displayed as a character string.

As an example, the work process area A1 displays the contents of the work process as a character string indicating the contents of the work process. The work amount area A2 displays numerical values and units such as the amount of extraction, the amount of injection, or the number of drugs as the amount of work in the work process. Specifically, the amount of work is the amount of extraction in the liquid extraction process or the drug extraction process, the amount of injection in the dissolution process, and the number of drugs that need to be authenticated in the drug authentication process. The work target area A3 displays identification information such as a name or code for identifying the work target in the work process. In addition, in the operation display unit 12, as described above, the preparation support screen D1 displays patient information and detailed information of the preparation data. Therefore, the user can check the details of the preparation work by referring to the preparation support screen D1 and the process screen D11 of the operation display unit 12. Here, for example, when various information cannot be displayed in the process screen D11, various information may be displayed by scrolling.

The buttons displayed on the screen of the operation items in the operation area A4 are objects included in the screen displayed on the operation display unit 12, and the operation of the buttons is an operation of the operation display unit 12 such as selecting the button. For example, the user can operate the "Close" button in the operation area A4 by performing an operation such as touching the button labeled "Close" on the operation display unit 12. Operating the "Close" button closes the process screen D11.

The support processing unit 31 of the control unit 11 may output the information related to the work process by voice, for example, in addition to or instead of displaying the information related to the work process on the operation display unit 12. This allows the user to recognize the information about the work process not only visually but also aurally, thereby reducing human error in the work process. The information related to the work process that is output by voice may be one or more of the content of the work process, the amount of work, and the work target.

<Step S18>
In step S18, the control unit 11 judges whether the current work process is the drug authentication process or not. If it is judged that the current work process is the drug authentication process (S18: Yes), the process proceeds to step S19, and if it is judged that the current work process is not the drug authentication process (S18: No), the process proceeds to step S20.

<Step S19>
In step S19, the control unit 11 executes a drug authentication process to determine whether the drug or liquid used in the preparation work is appropriate. Specifically, the control unit 11 waits for the second reading unit 21 to read the identification information of the drug or liquid, and when the identification information of the drug (the content identification information) is read, checks whether the content identification information matches the identification information of the drug or liquid in the preparation data to be read in the current drug authentication process. If the comparison result of the content identification information shows a match, the control unit 11 shifts the process to step S20. If the comparison result of the content identification information shows a mismatch, the control unit 11 reports an error and repeats step S19.

<Step S20>
In step S20, the control unit 11 judges whether the current operation is the tare subtraction process. If it is judged that the current operation is the tare subtraction process (S20: Yes), the process proceeds to step S21. If it is judged that the current operation is not the tare subtraction process (S20: No), the process proceeds to step S22.

<Step S21>
In the step S21, the control unit 11 executes a tare process for setting the weight of the syringe 203 used in the preparation work. Specifically, the control unit 11 waits for the syringe 203 to be placed on the weighing unit 22 and for the weighing value measured by the weighing unit 22 to become stable, and when the weighing value becomes stable, stores the weighing value in the memory unit 113 as the tare weight of the syringe 203, and transitions to the process of the step S22.

<Step S22>
In step S22, the control unit 11 judges whether the current work process is a measuring process such as the liquid measuring process or the medicine measuring process. If it is judged that the current work process is the measuring process (S22: Yes), the process proceeds to step S23, and if it is judged that the current work process is not the measuring process (S22: No), the process proceeds to step S24.

<Step S23>
In step S23, the control unit 11 executes a process for supporting the weighing process. Specifically, the determination processing unit 35 of the control unit 11 waits for the weighing object to be placed on the weighing unit 22 and for the weighing value by the weighing unit 22 (hereinafter referred to as the "actual weighing value") to be stabilized, and when the actual weighing value is stabilized, determines whether or not the difference between the actual weighing value and the weighing target value of the weighing object is within a preset error range. Then, when the determination processing unit 35 determines that the difference between the actual weighing value and the weighing target value is within the error range, that is, the actual weighing value is within the appropriate range, the determination processing unit 35 stores the actual weighing value in the storage unit 113 as a weighing result and transitions to step S24. Note that when the difference between the actual weighing value and the weighing target value is not within the error range, that is, when the actual weighing value is not within the appropriate range, the determination processing unit 35 reports an error and repeatedly executes step S23.

<Step S24>
In step S24, the control unit 11 judges whether the current work process is the photographing process such as the liquid photographing process or the medicine photographing process. If it is judged that the current work process is the photographing process (S24: Yes), the process proceeds to step S25, and if it is judged that the current work process is not the photographing process (S24: No), the process proceeds to step S26.

<Step S25>
In step S25, the control unit 11 executes a process for making the photographing unit 16 take an image. Specifically, the control unit 11 waits for a photographing operation by the photographing unit 16 using the operation input unit 15, and transmits a photographing request to the photographing unit 16 when the photographing operation is performed. This controls the photographing unit 16 to take a photograph by the photographing unit 16, and transmits the photographed image to the control unit 11. Then, after the control unit 11 displays the image on the operation display unit 12, when a confirmation operation is performed by the user, the control unit 11 associates the image with the preparation data and stores it as history data in the storage unit 113. Note that, when a re-photographing operation or the like is performed by the user, the control unit 11 can also cause the photographing unit 16 to take the image again by transmitting the photographing request to the photographing unit 16 again.

<Step S26>
In step S26, the control unit 11 judges whether the current work process is an "other work process" other than the medicine authentication process, the tare process, the weighing process, and the photographing process judged in steps S18 to S25. That is, the other work processes are the liquid extraction process, the dissolving process, the medicine extraction process, the co-injection process, etc. Here, if it is judged that the current work process is the other work process (S26: Yes), the process proceeds to step S27, and if it is judged that the current work process is not the other work process (S26: No), the process proceeds to step S17.

<Step S27>
In step S27, the control unit 11 executes a confirmation process for accepting a confirmation operation for the information on the other work process. Specifically, the control unit 11 waits for a confirmation operation for the work process, and when the confirmation operation is performed, the control unit 11 shifts the process to step S28. The confirmation operation is performed by a user using the operation display unit 12 or the operation input unit 15.

<Step S28>
In step S28, the control unit 11 judges whether or not all the steps of the preparation work based on the preparation data have been completed. If it is judged that all the steps have not been completed (S28: No), the process proceeds to step S17, and the same process is executed for the next step. If it is judged that all the steps have been completed (S28: Yes), the series of preparation support processes for the preparation data is completed, and the process is returned to, for example, step S15.

In this way, the preparation assistance process sequentially displays the work steps included in the preparation work based on the preparation data, allowing the user to proceed through the work steps in order by following the display.

[Display examples for each work process]
8 to 10, a display example of the process screen D11 when each work process included in the preparation work is executed will be described. However, here, the preparation support process when the total amount discarding process is not included in the preparation work will be described as an example. That is, a case will be described where the determination processing unit 36 determines that the total amount discarding process is not included in the preparation work.

Figures 8 to 10 show a schematic representation of the screen transition of the process screen D11 displayed on the operation display unit 12, with the process screen D11 transitioning (from top to bottom) along the arrows in each drawing. In the following, when multiple process screens D11 are to be distinguished from one another, each process screen D11 will be referred to as process screens D101 to D115. These multiple process screens D101 to D115 transition in the following order: process screen D101, process screen D102, process screen D103, ..., process screen D114, process screen D115.

<Drug authentication process>
Step screens D101 and D102 shown in FIG. 8 are display examples corresponding to the medicine authentication step.

In the process screen D101, the work process area A1 displays the text "Please authenticate" as the content of the work process. The work amount area A2 displays the text "Quantity: 0/1" as the work amount. The work target area A3 displays the text "Alimta (registered trademark) for injection 500 mg" as the work target.

If other drugs are also used in the preparation work, information corresponding to the drug authentication process for the other drugs is similarly displayed on the process screen D11. For example, in FIG. 8, the process screen D102 displays, as information on the drug authentication process for the other drugs, that the content of the work process is a drug authentication process, the work target is Alimta Injection 100 mg, and the work volume is 3 bottles.

<Tare process>
The process screen D103 shown in FIG. 8 is a display example corresponding to the tare subtraction process.

In the process screen D103, the work process area A1 displays the text "Please tare the empty syringe" as the content of the work process. In addition, the work target area A3 displays the text "50 mL syringe-1" as the work target.

<Liquid extraction process>
8 is a display example corresponding to the liquid extraction step. Here, a case is illustrated in which the liquid extraction step is not the total amount discarding step, but a "normal" liquid extraction step in which only a portion of the liquid in the infusion container 202 is extracted.

In the process screen D104, the work process area A1 displays the text "Please extract the dissolving liquid" as the content of the work process. The work amount area A2 displays the text "Dose: 32.6 mL" as the work amount, i.e., the amount of liquid to be extracted. The work target area A3 displays the text "500 mL of physiological saline solution" as the work target.

That is, in the normal liquid extraction process that is not the total amount discarding process, the support processing unit 31 issues a normal instruction to indicate the amount of the liquid contained in the infusion container 202 to be extracted. Specifically, in the process screen D104 displayed on the operation display unit 12 by the support processing unit 31, an instruction is given to indicate the amount of the liquid to be extracted, such as "Dose: 32.6 mL". As a result, the user extracts the specified amount (32.6 mL) of the liquid from the infusion container 202 in accordance with the process screen D104.

<Liquid Measuring Process>
The process screen D105 shown in FIG. 8 is a display example corresponding to the liquid measuring process.

In the process screen D105, the work process area A1 displays the text "Measure out the dissolving solution" as the content of the work process. The work amount area A2 displays the text "Dose: 32.6 mL" as the work amount. The work target area A3 displays the text "500 mL of saline solution" as the work target.

The control unit 11 may change the display mode, such as the text color of the work amount area A2, on the process screen D105 depending on whether the actual measurement value is within the appropriate range. Specifically, if the actual measurement value is not within the appropriate range, the control unit 11 sets the text color of the work amount area A2 to a first color, and if the actual measurement value is within the appropriate range, the control unit 11 sets the text color of the work amount area A2 to a second color.

<Liquid photography process>
The process screen D106 shown in FIG. 9 is a display example corresponding to the liquid photographing process.

On the process screen D106, the work process area A1 displays the text "Take an image" as the content of the work process. The work object area A3 displays the text "500 ml of saline solution" as the work object.

<Dissolving process>
Process screens D107 to D110 shown in FIG. 9 are display examples corresponding to the dissolving process.

In the process screen D107, the work process area A1 displays the text "Please dissolve" as the content of the work process. The work amount area A2 displays the text "Dissolution amount: 20 mL" as the work amount. The work target area A3 displays the text "Alimta for injection 500 mg" as the work target.

If other chemicals are also used in the preparation work, information corresponding to the dissolving process for the other chemicals is similarly displayed on the process screen D11. For example, in FIG. 9, in each of the process screens D108 to D110, the information on the dissolving process for the other chemicals indicates that the content of the work process is a dissolving process, the work target is Alimta Injection 100 mg, and the work volume is 4.2 mL.

<Chemical extraction process>
Step screens D111 and D112 shown in FIG. 10 are display examples corresponding to the drug extraction step.

In the process screen D111, the work process area A1 displays the text "Please remove" as the content of the work process. The work amount area A2 displays the text "Dose: 20 mL" as the work amount. The work target area A3 displays the text "Alimta for injection 500 mg" as the work target.

If other chemicals are also used in the preparation work, information corresponding to the chemical extraction process for the other chemicals is similarly displayed on the process screen D11. For example, in FIG. 10, the process screen D112 displays, as information on the chemical extraction process for the other chemicals, that the content of the work process is a chemical extraction process, the work target is Alimta injection 100 mg, and the work volume is 12 mL.

<Chemical measurement process>
The process screen D113 shown in FIG. 10 is a display example corresponding to the medicine measurement process.

In the process screen D113, the work process area A1 displays the text "Please measure" as the content of the work process. In addition, the work volume area A2 displays the text "Dose: 32 mL" as the work volume. In addition, the work target area A3 displays the text "Alimta for injection" as the work target. Note that the control unit 11 may change the display mode, such as the text color of the work volume area A2, depending on whether the actual measured value is within the appropriate range in the process screen D113.

<Medicine photography process>
The process screen D114 shown in FIG. 10 is a display example corresponding to the medicine photographing process.

In the process screen D114, the work process area A1 displays the text "Please take a picture" as the content of the work process. In addition, the work target area A3 displays the text "50 mL syringe-1" as the work target.

<Mixing process>
10 is a display example corresponding to the mixed injection process. In the process screen D115, a character string "Please mix injection" is displayed in the work process area A1 as the content of the work process.

As described above, in the preparation assistance system 1 according to this embodiment, information related to each work step of the preparation work can be displayed on the operation display unit 12. Therefore, the user can efficiently proceed with the preparation work by referring to the process screen D11.

It is also conceivable that the support processing unit 31 may display at least the work process area A1, the work amount area A2, and the work target area A3 on the process screen D11 in sequence at preset fixed intervals. This makes it possible to display the display contents of the work process area A1, the work amount area A2, and the work target area A3 enlarged on the operation display unit 12.

[Mode switching process]
Next, a mode switching process executed by the mode switching unit 37 will be described with reference to Figures 10 and 11. According to the mode switching process, the presentation mode is switched based on at least the user information.

Specifically, if it is determined that the user is an experienced user, the mode switching unit 37 selects the simplified display mode (the first mode), which omits the display of cumbersome procedures and instructions, as the presentation mode for displaying the process screen D11. On the other hand, if it is determined that the user is not an experienced user based on the user information, the mode switching unit 37 selects the detailed display mode (the second mode), which displays more detailed procedures and instructions, as the presentation mode for displaying the process screen D11.

For example, in the simple display mode, when the same work process is performed multiple times in succession for multiple drug containers 201 (or infusion containers 202) containing the same drug (or liquid), the support processing unit 31 performs a "summary display" in which these multiple work processes are displayed together on one process screen D11. In contrast, in the detailed display mode, when the same work process is performed multiple times in succession for multiple drug containers 201 (or infusion containers 202) containing the same drug (or liquid), the support processing unit 31 performs an "individual display" in which these multiple work processes are displayed individually on multiple process screens D11.

As an example, as shown in the process screen D111 and the process screen D112 in FIG. 10, it is assumed that the same work process (here, the drug extraction process) is executed multiple times in succession for multiple drug containers 201 that contain the same drug (here, "Alimta for injection").

In this case, in the detailed display mode, information related to the same type of drug extraction process is displayed multiple times in succession, as in the process screen D111 and the process screen D112 shown in FIG. 10. Specifically, the process screen D111 and the process screen D112 instruct the extraction of 20 mL and 12 mL of "Alimta for injection" from one drug container 201 corresponding to "Alimta for injection 500 mg" and the other drug container 201 corresponding to "Alimta for injection 100 mg", respectively.

In contrast, in the simplified display mode, information related to the same type of drug extraction process is displayed together, as in the process screen D11 shown in FIG. 11. Specifically, one process screen D11 instructs the user to extract a total of 32 mL of "Alimta for injection" from multiple drug containers 201 corresponding to "Alimta for injection." Such a summary display omits the display of procedures and instructions that are cumbersome for the experienced user, making it easier to achieve the preparation work more efficiently.

In addition, the display is not limited to the summary display and the individual display, and for example, in the simple display mode, the drug or liquid that is the work target, or the contents of the work process, may be displayed using an abbreviation. Specifically, if the liquid is "saline solution," the simple display mode may display the liquid using an abbreviation such as "saline," which can be distinguished from the detailed display mode in which the full name (saline solution) is used. The relationship between the first and second modes and the simple and detailed display modes is also not limited to the above example, and for example, the first mode may be the detailed display mode, and the second mode may be the simple display mode.

[Specific treatment of administration container]
Next, the identification process of the administration container executed by the identification process unit 32 will be described with reference to FIGS.

FIG. 12 is a diagram showing a part of the preparation support screen D1a and the preparation support screen D1b on which the contents of the preparation data are displayed. Both of the preparation support screens D1a and D1b include a prescription content area A10 showing the contents (prescription contents) of the preparation data. Here, as shown in FIG. 12, the display of the prescription content area A10 is different between the preparation support screen D1a and the preparation support screen D1b. Specifically, both of the preparation support screens D1a and D1b include "Abraxane (registered trademark) 100 mg" as the drug shown in the preparation data, and "physiological saline solution 100 mL" and "physiological saline solution 500 mL" as the liquid shown in the preparation data. However, the order in which "physiological saline solution 100 mL" and "physiological saline solution 500 mL" are displayed is different between the preparation support screen D1a and the preparation support screen D1b. The preparation data (or regimen information) is registered arbitrarily by each hospital, for example, so even if the prescription data (or regimen) is essentially the same, the order may differ in this way.

In such a case, if the infusion container 202 containing the liquid acquired first, that is, the infusion container 202 containing the liquid displayed in the first row of the prescription content area A10 among the infusion containers 202, is used as the administration container, the infusion container 202 containing "100 mL physiological saline" is indicated as the administration container on the preparation support screen D1a, and the infusion container 202 containing "500 mL physiological saline" is indicated as the administration container on the preparation support screen D1b. However, the capacity (maximum capacity) of the infusion container 202 containing "100 mL physiological saline" is at most 120 mL or less, and it cannot be used as the administration container for containing the prepared medicine, so in reality, the infusion container 202 containing "500 mL physiological saline" is used as the administration container. The preparation assistance system 1 according to this embodiment facilitates further efficiency of the preparation work by the identification process that identifies the container (the infusion container 202) that is actually used as the administration container.

Specifically, the control unit 11 executes the identification process according to a flowchart as shown in FIG. 13. In the following, an example will be described in which the preparation data of the preparation support screen D1a shown in FIG. 12 is used.

<Step S31>
In step S31, the control unit 11 acquires the container attribute information representing the attributes of the infusion container 202 for each container (the infusion container 202) containing the liquid indicated in the preparation data. Specifically, the control unit 11 focuses on the infusion container 202 indicated in the preparation data one by one, and acquires the container attribute information for the focused infusion container 202 from the medicine master. Since the preparation data indicates "100 mL of physiological saline" and "500 mL of physiological saline" in this order on the preparation support screen D1a, the control unit 11 first focuses on the infusion container 202 containing "100 mL of physiological saline" and acquires the container attribute information for the infusion container 202. The container attribute information includes at least information on the capacity of the infusion container 202. The capacity referred to here is the maximum capacity, and in the case of the infusion container 202 that contains "100 mL of physiological saline", it is, for example, "120 mL".

<Step S32>
In step S32, the control unit 11 judges whether the infusion container 202 of interest is the administration container candidate. Specifically, if the infusion container 202 of interest is registered as the administration container candidate in the medicine master, the identification processing unit 32 of the control unit 11 judges that the infusion container 202 is the administration container candidate (S32: Yes) and shifts the process to step S33. On the other hand, if the infusion container 202 of interest is not registered as the administration container candidate in the medicine master, the identification processing unit 32 judges that the infusion container 202 is not the administration container candidate (S32: No) and shifts the process to step S35.

<Step S33>
In step S33, the control unit 11 judges whether the infusion container 202 of interest is larger than the provisional administration container, i.e., has a large capacity. Specifically, the specific processing unit 32 of the control unit 11 compares the capacities (maximum capacity) of the infusion container 202 of interest and the provisional administration container. The provisional administration container is a flag set in step S34, and the capacity of the provisional administration container is set to "0" in the initial state. Then, if the capacity of the infusion container 202 of interest is larger than the capacity of the provisional administration container (S33: Yes), the specific processing unit 32 shifts the process to step S34. On the other hand, if the capacity of the infusion container 202 of interest is equal to or smaller than the capacity of the provisional administration container (S33: No), the specific processing unit 32 shifts the process to step S35.

<Step S34>
In step S34, the control unit 11 sets a provisional flag for the infusion container 202 of interest and registers the infusion container 202 as the provisional administration container. Specifically, the specific processing unit 32 of the control unit 11 first registers the infusion container 202 containing "100 mL of physiological saline" as the provisional administration container.

<Step S35>
In step S35, the control unit 11 judges whether a series of processes including the acquisition of the container attribute information (S31) has been completed for all the infusion containers 202 containing the liquid indicated in the preparation data. If it is judged that the processes for all the infusion containers 202 have not been completed (S35: No), the process proceeds to step S31 and the same process is performed for the next infusion container 202. On the other hand, if it is judged that the processes for all the infusion containers 202 have been completed (S35: Yes), the specific processing unit 32 proceeds to step S36.

<Step S36>
In step S36, the control unit 11 identifies the infusion container 202 registered as the provisional administration container at that time as the administration container. Specifically, the identification processing unit 32 of the control unit 11 sets an administration flag for the infusion container 202 as the provisional administration container, and identifies the infusion container 202 as the administration container. Specifically, the identification processing unit 32 of the control unit 11 identifies the infusion container 202 containing "500 mL of physiological saline solution", which has a relatively large capacity, as the administration container. The capacity (maximum capacity) of the infusion container 202 containing "500 mL of physiological saline solution" is, for example, "550 mL".

<Step S37>
In step S37, the control unit 11 judges whether the capacity (maximum capacity) of the administration container is greater than the total amount of the prepared medicine. Specifically, the propriety judgment processing unit 33 of the control unit 11 obtains the total amount of the prepared medicine from the preparation data, and compares the total amount (here, 540 mL) with the capacity of the administration container (here, 550 mL). If the capacity of the administration container is greater than the total amount of the prepared medicine (S37: Yes), the propriety judgment processing unit 33 shifts the process to step S39. On the other hand, if the capacity of the administration container is equal to or less than the total amount of the prepared medicine (S37: No), the propriety judgment processing unit 33 shifts the process to step S38.

<Step S38>
In step S38, the control unit 11 sets another container as the administration container. That is, in this case, since the total amount of the prepared medicine is equal to or larger than the capacity of the container (the administration container) having the largest capacity among the multiple infusion containers 202 indicated in the preparation data, the control unit 11 newly sets, as the administration container, a container (another container) other than the infusion container 202 that contains the liquid indicated in the preparation data and has a capacity capable of containing the prepared medicine.

<Step S39>
In the step S39, the control unit 11 presents the administration container to the user. Specifically, the support processing unit 31 of the control unit 11 presents the container identified as the administration container in the step S36 or the step S38 to the user by, for example, displaying it on the operation display unit 12.

The identification processing unit 32 may identify the administration container only when there are multiple containers that can be used as the administration container among the containers that contain the liquid indicated in the preparation data. In other words, when there is only one container that can be used as the administration container, only that container can be the administration container, and there is no need to identify the administration container based on the container attribute information. Therefore, the identification processing unit 32 may execute the identification process to identify the administration container only when there are two or more containers that are candidates for the administration container among the containers that contain the liquid indicated in the preparation data.

[Preparation support process when there is a total waste process]
Next, the preparation support process in the case where the entire amount discarding process is included in the preparation work will be described with reference to Fig. 12, Fig. 14, and Fig. 15. That is, the case where the determination processing unit 36 determines that the entire amount discarding process is included in the preparation work will be described.

As an example, assume that the preparation data includes "Abraxane 100 mg" and the liquids shown in the preparation data include "100 mL physiological saline" and "500 mL physiological saline", as shown in the preparation support screen D1a in FIG. 12. In this case, the preparation data indicates that "40 mL" of the "100 mL physiological saline" is to be used to dissolve the drug (Abraxane). In other words, the prescription content area A10 indicates that "40 mL" of the "100 mL physiological saline" is to be used. In such a case, after "40 mL" is extracted from the infusion container 202 containing "100 mL physiological saline", "60 mL" or more of the liquid (physiological saline) remains. Therefore, the preparation work indicated by the preparation data includes the total amount discarding process of discarding the total amount of the remaining liquid.

In such a case, if the extraction of the remaining liquid from the infusion container 202 containing "100 mL of physiological saline" is the normal liquid extraction process in which only a portion of the liquid in the infusion container 202 is extracted, the preparation support system 1 instructs the user on the amount to be extracted. Therefore, depending on the user, even though it is sufficient to extract the entire amount, the work of extracting the remaining liquid while adjusting the amount to be extracted with the syringe 203 may be more troublesome than necessary. In addition, if the extracted remaining liquid is judged as to whether the amount of the extracted liquid is appropriate by weight inspection or the like, the processing related to the judgment unnecessarily increases the processing load of the control unit 11. Furthermore, the actual amount to be extracted in the case of discarding the entire amount will be more than the amount to be extracted instructed by the preparation support system 1 by the amount of overfilling in the infusion container 202, so the judgment result of the appropriateness of the amount to be extracted may be inappropriate (an error). That is, in the above example, even though the extraction amount is specified as "60 mL," the actual extraction amount may be, for example, "65 mL" (5 mL being the overfill amount), and the judgment result of the appropriateness of the extraction amount may be inappropriate (an error). When there is a total amount discarding process, the preparation assistance system 1 according to this embodiment executes the preparation assistance process in accordance with the total amount discarding process, thereby resolving these problems and making it easier to further improve the efficiency of the preparation work.

Specifically, the control unit 11 executes the preparation support process differently depending on whether the total amount discarding process is included in the preparation work, according to a flowchart as exemplified in FIG. 14. FIG. 14 particularly shows the process related to the liquid extraction process among the preparation support processes. The following describes an example in which the preparation data of the preparation support screen D1a shown in FIG. 12 is used.

<Step S41>
In step S41, the control unit 11 judges whether the total amount discarding step is included in the preparation work. At this time, the control unit 11 and the judgment processing unit 36 judge whether the current liquid extraction step is the total amount discarding step based on the preparation data. Specifically, if a specific type of the drug that requires the total amount discarding step to be performed is indicated in the preparation data, the judgment processing unit 36 judges that the liquid extraction step is the total amount discarding step (S41: Yes) and shifts the process to step S42. On the other hand, if a specific type of the drug is not indicated in the preparation data, the judgment processing unit 36 judges that the liquid extraction step is not the total amount discarding step (S41: No) and shifts the process to step S44.

<Step S42>
In step S42, the control unit 11 issues the all-volume disposal instruction in a manner that can be distinguished from the normal instruction. Specifically, the support processing unit 31 of the control unit 11 issues the all-volume disposal instruction by displaying a process screen D121 as exemplified in Fig. 15 on the operation display unit 12. Fig. 15 shows a schematic representation of the screen transition of the process screen D11 displayed on the operation display unit 12, and indicates that the process screen D11 transitions (from top to bottom) along the arrows in each drawing. In other words, the multiple process screens D121, D122 transition in the order of process screen D121, process screen D122.

In the process screen D121, the work process area A1 displays the text "Extract and discard the entire amount" as the content of the work process. The work volume area A2 is left blank. The work target area A3 displays the text "100 ml of physiological saline solution" as the work target. The status area A5 displays the text "Discard the entire amount". In this way, the process screen D121 includes an instruction (the instruction to discard the entire amount) that allows the user to recognize that the remaining liquid is to be discarded in its entirety. In particular, in the example of FIG. 15, the process screen D121 leaves the work volume area A2 blank to avoid displaying information on unnecessary extraction amounts. When the button labeled "Confirm" in the operation area A4 is operated in the process screen D121, the control unit 11 transitions the process to step S43.

Upon receiving the instruction to discard the entire amount, the user can perform the discard of the entire amount for the work object. Specifically, the user uses the syringe 203 to extract and discard the remaining liquid from the infusion container 202 of "100 mL of physiological saline solution" as the work object. At this time, the user performs the extraction work without worrying about the amount extracted, since it is sufficient to extract the entire amount of the remaining liquid from the infusion container 202. In other words, if, for example, "65 mL" of liquid remains as remaining liquid after "40 mL" is extracted from the infusion container 202 containing "100 mL of physiological saline solution," the user extracts "65 mL" of the liquid.

<Step S43>
In step S43, the control unit 11 takes an image of the one container (the infusion container 202) that is the target of the total amount discarding process. Specifically, the recording processing unit 34 of the control unit 11 supports the user in taking the image by displaying a process screen D122 as shown in FIG. 15 on the operation display unit 12 after the total amount discarding process. In the process screen D122, a character string "Take an image of the empty container" is displayed in the work process area A1 as the content of the work process. Furthermore, a character string "100 ml of physiological saline solution" is displayed in the work target area A3 as the work target.

At this time, the recording processing unit 34 records the image data (image data) obtained by photographing the empty infusion container 202 with the photographing unit 16 as the empty container information by storing it in the memory unit 113. In addition to or instead of the image, the recording processing unit 34 may record, as the empty container information, an empty container flag indicating that the infusion container 202 is empty, and weight information of the empty infusion container 202 measured by the weighing unit 22. However, the empty container information does not necessarily require that the one container (the infusion container 202) is empty, and for example, even if some of the liquid remains in the container, the image of the container is recorded as the empty container information.

If the liquid extraction process is the total amount discarding process, the series of processes related to the liquid extraction process of the preparation support process ends with step S43. That is, in this case, the judgment processing unit 35 judges that the judgment condition is satisfied and does not execute the process related to the judgment of the appropriateness of the extracted amount. Since the process related to the judgment of the appropriateness of the extracted amount is not executed, naturally, the output process of the judgment result of the appropriateness of the extracted amount is not executed. That is, in this embodiment, with regard to the total amount discarding process, the empty container information can be left as proof (evidence) that the total amount has been discarded by a simple procedure without the trouble of an error being notified that the judgment result of the appropriateness of the extracted amount is inappropriate and then canceling the notification.

<Step S44>
In the step S44, the control unit 11 issues the normal instruction in a manner that can be distinguished from the all-amount discard instruction. Specifically, the support processing unit 31 of the control unit 11 issues the normal instruction by causing the operation display unit 12 to display, for example, the process screen D104 shown in FIG.

<Step S45>
Step S45 corresponds to the measurement process of step S23 in Fig. 5. That is, in step S45, the determination processing unit 35 of the control unit 11 determines whether or not the actual measurement value of the measurement object is within the appropriate range, using the extracted liquid as the measurement object, and further outputs the determination result.

<Step S46>
Step S46 corresponds to the photographing process of step S25 in Fig. 5. With step S46, a series of processes relating to the liquid extraction step of the preparation assistance process ends.

[Other features]
Even if the extraction process does not include the total amount discarding process, that is, if the judgment condition is not satisfied, the judgment processing unit 35 may not execute at least one of the process related to the judgment of the appropriateness of the extracted amount and the process of outputting the judgment result of the appropriateness of the extracted amount when a specific condition is satisfied. The specific condition includes, for example, that the extracted amount of the liquid exceeds a predetermined amount. The predetermined amount is set, for example, for each hospital, and is specifically the capacity of the syringe 203. For example, in the liquid extraction process, the liquid may be extracted and discarded not in its entirety but in part from a container such as the infusion container 202. In this case, if the extracted amount exceeds the capacity of the syringe 203, which is the predetermined amount, it is necessary to extract the liquid multiple times using the syringe 203. In such a case, the judgment processing unit 35 does not execute at least one of the process related to the judgment of the appropriateness of the extracted amount and the process of outputting the judgment result of the appropriateness of the extracted amount.

[Another configuration example of the preparation assistance system 1]
The preparation assistance system 1 according to another configuration example is configured to be able to cooperate with a preparation device 4, as shown in Fig. 16. The preparation device 4 performs at least a part of the preparation work on behalf of a user. In other words, the preparation device 4 can automate at least a part of the preparation work. In this configuration example, the preparation assistance system 1 supports a part or all of the preparation work that is automatically performed by the preparation device 4.

Specifically, the preparation assistance system 1 is configured to be able to communicate with the preparation device 4 via the communication network NT1, and executes an automatic preparation process that controls the preparation device 4 based on the preparation data. The preparation device 4 executes the preparation work according to the control related to the automatic preparation process. The preparation device 4 has a first robot arm 41, a second robot arm 42, and a container transport unit 43, each having a multi-joint structure. The first robot arm 41, the second robot arm 42, and the container transport unit 43 are arranged in a mixed injection processing chamber that corresponds to the work chamber 101 of the safety cabinet 100. The mixed injection processing chamber is equipped with an ampoule cutter, a stirring device, a placement shelf, a medicine reading unit, a weighing scale, a camera, a germicidal lamp, and the like.

The preparation device 4 automatically performs the preparation work using the dual-arm first robot arm 41 and the second robot arm 42 in accordance with a control signal from the preparation assistance system 1. Note that the preparation device 4 may have, for example, a configuration with one robot arm, a configuration including three or more robot arms, or a configuration without using any robot arms, as long as it has a structure capable of automatically performing the preparation work.

In the other configuration example, the support processing unit 31 controls the preparation device 4 to pour the prepared drug (the prepared drug) into a container identified as the administration container among the multiple containers (the infusion containers 202). In other words, instead of presenting the container identified as the administration container to the user, the support processing unit 31 controls the preparation device 4 to use the container as the administration container.

Even in the other configuration examples, the preparation assistance system 1 can execute the preparation assistance process when the total amount discarding process is included. That is, the preparation assistance system 1 can, for example, during the total amount discarding process, issue the total amount discarding instruction to the preparation device 4, cause the preparation device 4 to record the empty container information, or not cause the preparation device 4 to execute a judgment on the appropriateness of the amount of extraction.

Here, the means by which the preparation device 4 executes the total disposal of the remaining liquid in the container such as the infusion container 202 is not particularly limited, but as an example, please refer to FIG. 59 of REPRESENTATION Pub. No. 2015/041092 and the explanation related to FIG. 59. The preparation assistance system 1 may be integrated with the preparation device 4.

[Modification]
The plurality of components included in the preparation assistance system 1 may be distributed among a plurality of housings. Conversely, the plurality of components (such as the operation display unit 12 and the photographing unit 16) distributed among a plurality of housings in the above embodiment may be integrated into one housing.

In the above embodiment, the identification processing unit 32 identifies the container with the largest capacity among the multiple containers as the administration container, but this is not limited thereto. The identification processing unit 32 may identify the administration container based on the container attribute information. For example, the identification processing unit 32 may identify a container of a predetermined type (a plastic bottle, as an example) as the administration container based on the container attribute information.

The identification processing unit 32, which identifies the administration container, is not essential for the preparation assistance system 1 and may be omitted as appropriate. Similarly, the feasibility determination processing unit 33, the recording processing unit 34, the judgment processing unit 35, the judgment processing unit 36, and the mode switching unit 37 are not essential for the preparation assistance system 1, and at least one of these functions may be omitted as appropriate.

Depending on the type of drug, it may be necessary to leave the drug container 201 stationary for a certain period of time during the dissolving process, between the time the liquid is poured into the drug container 201 and the time the liquid is removed. When this type of drug is indicated in the preparation data, the preparation assistance system 1 may start timing the certain period of time upon receiving, for example, from a user, an input indicating that the drug container 201 has been left stationary, and may notify (present) the user of the end of the leaving period of time after the certain period of time has elapsed.
