Description

  The present invention relates to an automatic recognition system for used injections. More specifically, the present invention relates to an automatic recognition system that recognizes medicines used / discarded in an emergency such as operating rooms, critical care wards, and intensive care units with a camera.

  Conventionally, in a drug inventory management system, a doctor places a prescription order for a patient in a general ward on the day before the application date, and the pharmacist inputs the amount of injection drug dispensed from the drug warehouse based on that order as a consumption quantity, or enters the medical The amount of medicine used extracted from the medical office system that runs on the host computer of the institution is used as the consumption quantity.

  As a medicine inventory management system, for example, a medicine inventory management system as shown in FIG. 5 has been proposed. In this medicine inventory management system, the storage device 101 stores an injection data conversion master composed of master data used for the conversion process between the amount of medicine used and the amount of medicine to be dispensed. The control device 102 fetches the amount of medicine used contained in the injection dispensing data from the injection medicine dispensing control system 105 that controls the operation of the injection medicine dispensing devices 103 and 104 based on the injection prescription data, and stores the medicine usage amount in the memory. Based on the injection data conversion master read from the apparatus 101, the amount is converted into the amount of medicine to be injected, and the scheduled amount of medicine to be paid out by each paying department is determined (see Patent Document 1).

JP 2001-350842 A (Abstract, FIG. 1)

  However, there are many hospitals that use placement drugs at the time of surgery, treatment at a critical care hospital, and treatment at the ICU. In this case, the nurse uses empty bottles of injections that are used or discarded in the operating room or ICU treatment room. There is a problem that inspections are performed according to medicines and volumes, and doctors must input (or describe) these consumption quantities after the fact, which increases the wasteful work of doctors and nurses.

  Therefore, when performing post-entry input, there are many input (description) mistakes such as missing inspections and forgetting doctor's input (description), and there is a problem that the leakage due to these becomes large throughout the year and pressures management. is there.

  In general wards, doctors prescribe orders for patients the day before application, and pharmacists often supply injections to patients on the day of application and supply them to the ward on the day of application. Since injections are prepared the day before, if the test result or condition changes suddenly, the placement drug is used. In this case as well, the nurse must inspect the empty bottles of the used injections by medicine and volume, and the doctor must enter (or describe) the consumption quantity etc. afterwards. There are many input (description) mistakes such as forgetting to input (description).

  The present invention was devised in view of the above points, and it is possible to prevent input errors by automatically picking used chemicals, specifying the type with a camera, and entering inspection / consumption. An object of the present invention is to provide an automatic recognition system.

  First, the patient is transported from the ward to the operating room (step S1). A label with the application date and patient ID barcode printed as patient information is affixed to the collection box for discarding used containers such as ampoules, vials or syringes, and placed in the operating room. (Step 2).

  Next, the storage container for the injection used during the operation is discarded in the collection box (step S3). In this case, the needle of the syringe is removed and discarded into a separate needle disposal container or the like.

  Then, after the operation is completed, the nurse or the transport staff transports the collection box in which the storage container for the injection medicine is discarded in step S2 to the post-management center, and patient information (bar) printed on the label attached to the collection box. The patient can be identified by reading the code) with a reading device and collating patient information previously recorded in the personal computer. (Step S4).

  Next, storage containers such as ampules, vials or syringes of used injections stored in the recovery box are stored in the recovery box 2 by the automatic picking device 1 as shown in FIG. The storage container is picked by automatically recognizing its shape and picking position with a camera (step S5).

  In step S5, the storage containers such as the ampules, vials, and syringes picked are set one by one on the recognition table. The recognition table is provided with a camera for identifying the type of injection described in the storage container. The upper and lower sides of the storage container set on the recognition table are fixed with arms, and then rotated 360 degrees. Drug information such as written characters, labels, or barcodes is read and collated with image data as information on various injections that are entered and recorded in a personal computer in advance, enabling the identification and recognition of injections. It becomes possible (step S6).

  After recognizing the type of injection in step S6, post-hoc data is created and at the same time a prescription for the operating room is output and the prescription is confirmed by the doctor, and the post-hoc data is transmitted to the medical department by in-hospital communication. The medical request data is processed (step S7).

  Further, after the type of the injection drug is specified in step S6, the ampule vial and the syringe are separated by the picking device, and the separately separated injection drug and syringe are disposed of (step S8).

Example 2
FIG. 3 is a flowchart showing an example of the used medicine automatic recognition system of the present invention in a lifesaving emergency center.

  An emergency patient is transported to an emergency medical center by an ambulance and is immediately carried into the emergency medical room (step S11).

  Then, the patient's emergency treatment is performed, and the storage container such as the ampule, vial or syringe of the used injection used at that time is discarded in the collection box. At this time, the needle of the syringe is removed and discarded in a separately disposed needle disposal container or the like (step S12).

  At the end of the therapeutic treatment in step S11, a label on which patient information (barcode) such as application date and patient ID is printed is output and attached to the collection box (step S13).

  Next, the collection box where the storage containers such as ampules, vials or syringes for used injections are discarded is transported to the post-management center, and patient information (barcode) written on the label attached to the collection box is displayed. A patient can be identified by collating patient information read and recorded in advance in a personal computer by a reading device. (Step S14).

  Here, as shown in FIG. 2, the storage container stored in the recovery box has a shape of a plurality of types of storage containers such as ampoules, vials, and syringes stored in the recovery box 2 by the automatic picking device 1. The picking position is automatically recognized by the camera for picking (step S15).

  The storage containers picked in step S15 are set one by one on the recognition table. The recognition table is provided with a camera for identifying the type of injection drug described in the storage container, and the upper and lower sides of the storage container set on the recognition table are fixed with arms, and then rotated 360 degrees. By reading the written characters, labels, or barcodes and collating them with image data as information on various injections that have been input and recorded in a personal computer in advance, it becomes possible to identify and recognize the injection ( Step S16).

  After the type of the injection is recognized in step S16, post-event data is created, and at the same time, the nurse or the transport staff brings the prescription output from the post-hospital management center and performs filing after confirmation with the doctor. In the case of an electronic medical record, it is also possible to transfer data to a personal computer in the emergency room (step S17).

  Further, after the type of the injection medicine is specified in step S16, the ampule vial and the syringe are separated by the picking device, and the injection medicine and the syringe thus separated are discarded (step S18).

Example 3
FIG. 4 is a flowchart showing an example of the used medicine automatic recognition system of the present invention in the ICU / general ward.

  When the patient's condition changes suddenly, the injection drug placed in the ward is used (step S21). Then, storage containers such as ampules, vials or syringes of used injections used for treatment are discarded in the collection box. At this time, the needle of the syringe is removed and discarded in a separate needle disposal container or the like (step S22).

  After the treatment in step S21, a label on which patient information (barcode) such as application date and patient ID is printed is output and attached to the collection box (step S13).

  Next, the collection box where used containers such as ampoules, vials or syringes are discarded is transported to the post-management center, and patient information (barcode) printed on the label attached to the collection box is displayed. A patient can be identified by collating patient information read and recorded in advance in a personal computer by a reading device. (Step S24).

  Here, as shown in FIG. 2, the storage container stored in the recovery box stores ampoules, vials, syringes, etc. of a plurality of types of used injections stored in the recovery box 2 by the automatic picking device 1. The container is picked by automatically recognizing its shape and picking position with a camera (step S25).

  The storage containers picked in step S25 are set one by one on the recognition table. A camera for identifying the injection is installed on the recognition table, and the upper and lower sides of the storage container set on the recognition table are fixed with arms, and then rotated 360 degrees, and the characters, labels, or By reading the bar code and collating it with image data as information on various injections that are input and recorded in advance in a personal computer, the injection can be identified and recognized (step S26).

  After the type of the injection is recognized in step S26, the post-mortem data is created and the prescription is output at the same time. The nurse or the transport staff brings the prescription and performs filing after confirmation with the doctor. In the case of an electronic medical record, it is also possible to transfer data to a personal computer in the ICU / general ward (step S27).

  Further, after the type of the injection medicine is specified in step S26, the ampule vial and the syringe are separated by the picking device, and the separated injection medicine and the syringe are discarded (step S28).

In Examples 1 to 3, the collection box is made of a material that can be washed with water so that it can be reused, for example, a synthetic resin material such as plastic. In order to prevent this, it is desirable that there is a mesh-shaped tray with an inclination at the bottom of the collection box, and the leaked residual liquid is accumulated in the lower part through the mesh.
Moreover, since only the consumption amount is inspected for chemicals that require notification such as anesthetics, it is necessary to check the residual liquid in the container, and it is desirable to provide an area in the collection box where the residual liquid does not leak.

Also, in Examples 1 to 3, if there is a residual liquid of a special injection such as an anesthetic in the injection, a measuring device is provided on the recognition table, and at the same time the anesthetic is recognized by the camera, It becomes possible to measure and recognize consumption by measuring.
Furthermore, in Examples 1-3, the post-mortem management center is described in detail assuming that it is installed in a hospital. For example, in the case of a contract with a group medical corporation or hospital consisting of a plurality of hospitals, It is also possible to set up an ex-post management center outside the hospital, transport the collection box from the hospital, send only the data to the hospital, and process the collected containers such as ampoules and vials at the post-management center.

  In addition, when the barcode cannot be output to the collection box, it is desirable to have the patient ID / date of application written by hand and manually input the information to the personal computer at the post-management center. For storage containers for used injections that cannot be picked, after the collection box is transported to the post-management center, the patient ID and date of application are recognized, then the injection is selected on the touch panel, or used injections are stored. Be able to respond by reading the barcode on the container.

  In addition, the expiration date and lot number written on the storage container for used injections can be read at the same time when the type of the injection is recognized by the camera, so which lot number is used for anyone such as products of specific biological origin. As a result, it is possible to manage the data as data, and by grasping the lot number and the expiration date, it is possible to reduce the risk, for example, by collecting the near-expired injection or the expired injection based on the lot number.

  In the present invention having the above-described configuration, when using a drug placed in an operating room, a critical care center, and a general ward / ICU room, an injection drug and a syringe that are discarded into a collection box after the treatment are classified by type by a picking device. By picking and recognizing characters, labels, and barcodes written on the injection by the camera, it is possible to reliably grasp the amount of medicine used.

  Therefore, by automatically inspecting the amount of medicine used, the workload of doctors, pharmacists and nurses can be greatly reduced, and the amount of medicine used can be ascertained reliably. Or it is possible to eliminate waste of inventory management.
