JP7614718B2 - Judgment system and aggregation server - Google Patents

Description

This disclosure relates to a determination system and an aggregation server.

There have been attempts to manage the health of elderly people living in elderly care facilities by recording their bowel movements. However, when bowel movements are recorded manually by caregivers, the recording is time-consuming and involves subjectivity, which can lead to subjective judgments about the properties of the excrement, resulting in inconsistent judgment results.

On the other hand, there is a technology that can objectively determine the properties of excrement from images of the excrement. For example, a technology has been disclosed that estimates the properties of excrement from multiple still images taken of the excrement as it falls (see, for example, Patent Document 1). If the results of determining the properties of excrement using this technology are used as a defecation record, it is possible to reduce the effort required for recording and the possibility of fluctuations in the determination results.

JP 2017-137707 A

When attempting to use the technology of Patent Document 1 for health management, there is still room for improvement. For example, many people in elderly care facilities tend to suffer from constipation. For this reason, the contents of the bowel movement records are used to determine whether or not to administer a laxative, and control is performed to prevent too much stool from building up in the stomach. However, if too much laxative is administered, diarrhea will recur, which can lead to dehydration. For this reason, the amount of medication must be adjusted for each user. There was a need for a system that could manage health by taking such various circumstances into consideration.

This disclosure has been made in light of these circumstances, and its purpose is to provide a determination system and aggregation server that can perform health management based on bowel movement records while taking into account various circumstances.

In order to solve the above-mentioned problems, one embodiment of the present disclosure is a determination system including: an acquisition unit that acquires image information of a target image in which excrement is captured; a determination unit that determines the properties and/or amount of the excrement in the target image; a medication information input unit to which medication information related to excretion is input; a generation unit that generates excretion information that corresponds a determination result in which the properties and/or amount of the excrement are determined, information indicating the excretion time when the excretion was excreted, and user information regarding the user corresponding to the excretion; and a notification control unit that displays the properties and/or amount of the excretion for each user, and if the properties and/or amount of the user's excretion satisfy an alert condition set for the user , notifies alert information indicating this and information on whether the dosage is appropriate or excessive , and displays the presence or absence of excretion and the medication information in chronological order.

FIG.

The following describes the embodiment of the determination system with reference to the drawings.

As shown in FIG. 1, the determination system 1 includes, for example, a plurality of determination devices 10 (determination devices 10-1, 10-2, ..., 10-N), a plurality of operation terminals 20 (operation terminals 20-1, 20-2, ..., 20-N), and an aggregation server 50. The determination device 10 is connected to the operation terminal 20. The operation terminal 20 and the aggregation server 50 are connected via a communication network NW. Note that the configuration of the determination system 1 is not limited to this example. The determination system 1 may be configured to include a pair of the determination device 10 and the operation terminal 20, or may be configured to include a plurality of aggregation servers 50.

The determination device 10 determines the properties and/or amount of excrement (hereinafter also referred to as stool) captured in an image based on the captured image. The properties of excrement are indicators of the properties and state of the stool. The properties of excrement are, for example, the shape and color of the stool. The properties of excrement are, for example, classified into seven categories based on the Bristol scale. The Bristol scale indicates the properties and state of the stool and is an international classification index of stool that is often used in medical settings. In the following explanation, an example will be described in which the properties of stool are classified into five categories: hard stool, normal stool, soft stool, muddy stool, and watery stool. In the following explanation, the properties of stool may be expressed as the "shape of stool" or the "form of stool". The amount of excrement includes the size of the excrement.

The operation terminal 20 notifies the aggregation server 50 of the excretion information including the determination result by the determination device 10 based on the operation input by the operator of the operation terminal 20. The operation input is performed, for example, by performing a touch operation on a touch panel (see FIG. 4) on which the excretion information is displayed.

The excretion information is information about the excretion of the user (excretor), and is information indicating the contents recorded as a conventional defecation record. For example, the excretion information is information associated with the user, such as the presence or absence of excretion, the amount of excretion, the properties of the excretion, the excretor, and the time of excretion. When the determination system 1 is applied to an elderly care facility, the operator of the operation terminal 20 is, for example, a caregiver who cares for the elderly. In this case, the caregiver operates the operation terminal 20 to record the excretion of the user (here, the elderly resident). For example, the caregiver takes care of the user's excretion, and when excretion occurs, judges whether the judgment made by the judgment device 10 is appropriate, and corrects it if necessary to confirm the contents. The caregiver inputs the user's name, etc., and performs an operation to notify the aggregation server 50. As a result, the operation terminal 20 notifies the aggregation server 50 of the excretion information.

The aggregation server 50 aggregates the excretion information notified by the operation terminal 20. When the determination system 1 is applied to an elderly care facility, the aggregation server 50 is installed, for example, in the staff room. The staff room is a so-called care station, and is a place where caregivers wait, information is exchanged, and care policies are established. The aggregation server 50 collectively manages the excretion records of all residents in the elderly care facility, and displays the whole or part of the excretion records in response to operation input.

The aggregation server 50 acquires, together with the excretion information, medication information for the user corresponding to the excretion information. The medication information is information indicating the administration history of medication related to excretion.

Drugs related to excretion include, for example, laxatives or antidiarrheal drugs. In particular, many elderly people in elderly care facilities tend to be constipated, and laxatives are often administered. Elderly people are often prescribed oral liquid laxatives, and with these types, 10 to 15 drops are orally administered once a day. Initially, 10 drops are started, and if there is no effect, the amount may be increased by one drop every other day while observing the condition. The number of drops that are effective varies from person to person, and administering the same amount that was effective in the past may not have the same effect. If too much laxative is administered, diarrhea will recur, which can lead to dehydration. For this reason, when administering a laxative, the dosage must be carefully determined.

As a countermeasure, the aggregation server 50 displays the medication history in chronological order along with the excretion records. Specifically, the aggregation server 50 displays the relationship between the amount of medication administered and the properties of the excreta after administration. This makes it easier for the viewer to determine whether the medication is effective, whether the dosage is too much or too little, etc.

The aggregation server 50 includes, for example, a communication unit 51, an input unit 52, a determination unit 53, a display unit 54, a display control unit 55, and a memory unit 56. The display control unit 55 is an example of an "operation control unit". The communication unit 51 communicates with the operation terminal 20 via the communication network NW, and receives, for example, excretion information from the operation terminal 20. The communication unit 51 outputs the acquired excretion information to the determination unit 53 and the display control unit 55.

The input unit 52 acquires information input by an operator of the aggregating server 50. The operations performed by the operator of the aggregating server 50 include, for example, input of various information and manipulation of display content. The input of various information is, for example, the medication information described above. In this case, the input unit 52 is an example of a "medication information input unit."

Operations performed by the operator of the aggregation server 50 include correcting the excretion information notified from the operation terminal 20, and inputting excretion information determined by a person other than the determination device 10. The excretion information determined by a person other than the determination device 10 is the result of a caregiver determining the characteristics of stool when excretion occurs in a place where the determination device 10 is not installed (such as a bathroom or bedroom) in an elderly care facility. The operation of the display content includes displaying a list of all the excretion information notified to the aggregation server 50, or displaying excretion information corresponding to a specified user or a specified date and time. The input unit 52 outputs the acquired information to the display control unit 55.

The determination unit 53 determines the health condition related to excretion based on the excretion information, etc. The health condition related to excretion here is the health condition of the user that can be determined from the excretion information and the medication information, and is, for example, whether there is regular excretion or whether there is a bias in the properties of the excretion (hard stool or watery stool). Such conditions, such as whether there is regular excretion or whether there is a bias in the properties of the excretion (hard stool or watery stool), are examples of "alert conditions". For example, the determination unit 53 derives the interval between defecation (defecation interval) based on the excretion information. The defecation interval is the interval of time during which there is no defecation, and is the elapsed time from the time of the latest excretion (excretion time) to the current time. If the defecation interval is longer than a predetermined threshold, the determination unit 53 determines that the health condition is deteriorating. For example, if watery stool is excreted a predetermined number of times in succession, the determination unit 53 determines that the health condition is deteriorating. If the excrement after taking the laxative is irregular (hard stool or watery stool), the determination unit 53 determines that the dosage is inappropriate and that the health condition is deteriorating. If the determination unit 53 determines that the health condition is deteriorating, it outputs information indicating that to the display control unit 55.

The display unit 54 displays an image under the control of the display control unit 55. The display control unit 55 controls the contents to be displayed on the display unit 54. The display control unit 55 determines the display contents and display mode to be displayed on the display unit 54 based on the information on the display input by the input unit 52. For example, the display control unit 55 first displays, for each user, the presence or absence of excretion in chronological order, the properties of the excretion if there was excretion, and the presence or absence of medication (see FIG. 5). The display control unit 55 may display detailed information on the selected excretion (see FIG. 6). When a specific user is selected by the operator's operation input, the excretion record of the selected user is displayed in a calendar-type display mode (see FIG. 7). The display control unit 55 may display the details of the properties of the excretion of the selected user over a predetermined period (for example, one month) in a bar graph-type display mode (see FIG. 8). The storage unit 56 stores the excretion information and the medication information in association with the user.

As shown in FIG. 2, the determination device 10 is connected to an imaging device 4 that captures an image of the toilet device 3.

The toilet device 3 includes, for example, a toilet 30 having a toilet bowl 32. The toilet device 3 is configured to be able to supply flushing water S to an opening 36 provided in the internal space 34 of the toilet bowl 32.

The imaging device 4 is provided in a position where it can capture an image of excrement. The imaging device 4 is installed on the upper side of the toilet bowl 30, for example, on the inside edge of the rear side of the toilet bowl 32, with the lens facing toward the internal space 34 of the toilet bowl 32. In other words, the imaging device 4 is installed so that it can capture an image of the internal space of the toilet bowl 32. The imaging device 4 captures an image of the internal space of the toilet bowl 32, for example, based on instructions from the determination device 10, and transmits image information of the captured image to the determination device 10.

The imaging device 4 repeatedly captures images of the internal space of the toilet bowl 32 over time in accordance with the time series of excretion. For example, the imaging device 4 captures multiple images at the start, middle, and end of excretion. This makes it possible to analyze the images in the time series in which they were captured, and to determine which feces were excreted first, which feces were excreted in the middle, and which feces were excreted last.

In the following description, the imaging device 4 captures an image of excrement that has fallen into the toilet bowl 32, but this is not limited to the example. The imaging device 4 may be installed, for example, on the underside of the toilet seat, and capture images of the excrement as it falls from the side of the toilet bowl 32. The images captured by the imaging device 4 may be moving images or still images.

The determination device 10 includes, for example, an image information acquisition unit 11, an analysis unit 12, a determination unit 13, an output unit 14, an image information storage unit 15, a trained model storage unit 16, and a determination result storage unit 17. The image information acquisition unit 11 is an example of an "acquisition unit."

The image information acquisition unit 11 acquires image information of an image (target image) of the internal space 34 of the toilet bowl 32. The image information acquisition unit 11 outputs the acquired image information to the analysis unit 12. The image information acquisition unit 11 stores the acquired image information in the image information storage unit 15.

The analysis unit 12 analyzes the image (target image) based on the image information obtained from the image information acquisition unit 11. The analysis by the analysis unit 12 involves estimating the items for judgment (judgment items) related to excrement based on the image related to excretion. The judgment items may be at least items related to excrement, such as the properties and/or amount of stool.

The analysis unit 12 estimates the judgment items, for example, using a trained model that has learned the content corresponding to the judgment items of the judgment unit 13. The trained model is, for example, a model stored in the trained model storage unit 16, and is a model that has been trained using as training data a data set that associates images of excrement (training images) with judgment results for the judgment items of the excrement captured in the images. Through such learning, the trained model can output the results of judging the judgment items in the input image as estimated values.

The trained model is created, for example, using a deep learning (DL) technique. DL is a machine learning technique that uses a deep neural network (DNN) that is composed of a multi-layered neural network. A DNN is realized by a network inspired by the principles of predictive coding in neuroscience, and is constructed by a function that mimics a neural transmission network. However, it is not limited to this. The trained model may be a model that has at least learned the correspondence between images and judgment results.

The determination unit 13 uses the analysis results (estimated results) obtained from the analysis unit 12 to determine the determination items for the excrement captured in the target image.

The output unit 14 outputs the judgment result by the judgment unit 13. The output unit 14 may transmit the judgment result to, for example, the terminal of the user who performed the excretory behavior. This allows the user to recognize the judgment result of the properties and amount of excrement. The image information storage unit 15 stores the image information acquired by the image information acquisition unit 11. The trained model storage unit 16 stores trained models corresponding to each of the judgment items. The judgment result storage unit 17 stores the judgment result by the judgment unit 13. The communication unit 18 communicates with the toilet device 3 and the imaging device 4, or an external device (not shown). For example, when a functional unit (not shown) provided on the toilet device 3 to the toilet 30 detects the user's sitting or getting up from the toilet device 3, the start of use of local washing, and the operation of washing the toilet bowl 32 after excretion, the communication unit 18 receives the detection result. The communication unit 18 transmits control information indicating an instruction to capture an image to the imaging device 4.

As shown in FIG. 3, the operation terminal 20 includes, for example, a communication unit 21, an input unit 22, a display unit 23, a control unit 24, and a memory unit 25. The communication unit 21 communicates with the determination device 10 and acquires a determination result from the determination device 10. The communication unit 21 communicates with the aggregation server 50 via the communication network NW and transmits excretion information to the aggregation server 50. The input unit 22 acquires information input by the operator of the operation terminal 20.

The input unit 22 acquires various information input by the operator of the operation terminal 20. For example, information (confirmation information) indicating the result of determining whether the determination made by the determination device 10 is valid is input to the input unit 22. In this case, the input unit 22 is an example of a "confirmation information input unit." Information indicating the correction content for correcting the determination made by the determination device 10 is input to the input unit 22. Information indicating the user's name, etc. is input to the input unit 22.

The display unit 23 displays the result of the determination made by the determination device 10. The result of the determination is the presence or absence of defecation, the shape of the excrement, and the amount of the excrement, determined from an image of the excrement. The display unit 23 may display various images used for inputting operations. In this case, the display unit 23 includes a touch panel that can acquire touch operations performed on the screen. In this case, the touch panel functions as the input unit 22.

The various images used for operation input are, for example, an image showing the word "Confirm" to confirm whether or not the judgment made by the judgment device 10 is valid. The various images used for operation input are, for example, an image showing the word "Correct" to correct the judgment made by the judgment device 10. The various images used for operation input are, for example, an image showing the word "Input" to input the user's name, etc.

The control unit 24 generates excretion information that associates the judgment result obtained from the judgment device 10 with user information related to the user. The control unit 24 is an example of a "generation unit." The control unit 24 generates the excretion information, for example, by associating the judgment result obtained from the judgment device 10 with user information input through the input unit 22.

When information indicating that the result of the determination by the determination device 10 has been confirmed by a caregiver or the like is input from the input unit 22, the control unit 24 may generate excretion information including that information. In this case, the control unit 24 generates excretion information by associating the information indicating whether the result of the determination by the determination device 10 has been confirmed with the determination result.

The control unit 24 may generate excretion information including information indicating whether the judgment result was judged by the judgment device 10. In this case, based on the excretion information, it is possible to distinguish whether the judgment result was judged by the judgment device 10 installed in the toilet device 3 or was judged by a caregiver or the like for excretion that took place in a bathroom or the like where the judgment device 10 is not installed. The control unit 24 notifies the aggregation server 50 of the generated excretion information via the communication unit 21.

The storage unit 25 stores user information of users who are managed by the determination system 1. The storage unit 25 stores the determination results determined by the determination device 10.

As shown in FIG. 4, the display unit 23 of the operation terminal 20 displays the judgment result by the judgment device 10. In this example, the judgment result by the judgment device 10 is the result of judging whether or not there is stool, the amount of stool, and the shape of stool. In this example, the input unit 22 displays the presence or absence of stool (yes/no), the amount of stool (small/medium/large), and the shape of stool (hard stool/normal stool/soft stool/mudgy stool/watery stool) in characters and figures (illustrations), and the judgment result by the judgment device 10 is shown by surrounding the corresponding characters and figures (illustrations) with a frame. In this example, at least a part of the front screen on the display unit 23 is composed of a touch panel and functions as the input unit 22. For example, when the operator touches the correction image 210, the judgment result by the judgment device 10 can be corrected. When the operator touches the confirmation image 211, the judgment result by the judgment device 10 can be confirmed. When the operator touches the registration image 212, the judgment result by the judgment device 10 can be notified to the aggregation server 50. As shown in this example, the display unit 23 may display a message indicating the progress of processing by the determination device 10, such as "Excretion check completed." The display unit 23 may also display the date and time when the determination was made by the determination device 10 (determination time).

As shown in FIG. 5, the display unit 54 of the aggregation server 50 displays the excretion and medication history for each user in chronological order. The display unit 54 displays items such as alert, room, name, defecation interval, and time axis. An alert is displayed in the column of a user whose health condition has been determined to be declining by the determination unit 53, with text or a figure indicating this. In this example, when there is an alert, an exclamation mark is displayed.

The room number in which the user occupies is displayed in the room field. The name field shows the user's name. The defecation interval field shows the time from the most recent defecation time to the current time. If the defecation interval is longer than a predetermined threshold time (e.g., 12 hours), the display mode of the defecation interval is changed and displayed more prominently. In this example, if the defecation interval is 15 hours, which is longer than the threshold time (12 hours), it is displayed in bold and larger letters compared to when the defecation interval is shorter than the threshold time.

In the time axis items, the history of excretion and medication is displayed in chronological order using text and figures. In this example, image 540 of a drop indicates that urination has occurred. In this way, the determination system 1 may collect records of urination as well as defecation. Image 541 resembling excrement indicates that defecation has occurred. Image 542 of a capsule indicates that medication has been administered. In image 541, the nature is indicated by the color and density of the image. For example, image 541 indicates watery stool, image 544 indicates hard stool, and image 546 indicates muddy stool.

The image 543 of an exclamation mark indicates that some kind of comment has been recorded. Such a comment is input by the operator of the operation terminal 20, for example, when the operator confirms the judgment result of the judgment device 10. The comment records content that requires special attention, such as, for example, that although it has been judged to be hard stool for convenience, it is actually not simply muddy stool but tarry stool like that seen when bleeding comes from the digestive organs.

The question mark image 545 indicates that the result of the determination by the determination device 10 has not been finalized. In this case, if the operation terminal 20 displays the result of the determination by the determination device 10 but a predetermined time has passed without any operation input being made after the display, the operation terminal 20 notifies the aggregation server 50 of excretion information including information indicating that the result of the determination has not been finalized.

When the operator selects each of the images 540 to 546 by touching or otherwise operating the image, the specific details are displayed. For example, when image 541 is selected, the specific judgment details associated with image 541, i.e., the time of excretion, the amount of stool, the shape of stool, the presence or absence of comments, the presence or absence of urination, etc., are displayed. At this time, the operator can correct the judgment details or add comments. When image 545 or 546 is selected, the operator corrects the details, and the judgment result by the judgment device 10 is confirmed, the question mark image 545 is displayed on the display unit 54 from the next time onwards. When the details image 547 is selected by touching or otherwise operating the image, the detailed details of the user are displayed (see FIG. 6).

As shown in FIG. 6, when the detailed image 547 shown in FIG. 5 is selected, the display unit 54 of the aggregation server 50 displays the excretion and medication history for each user in chronological order. The display unit 54 displays, for example, a time axis, speech bubbles, etc. The excretion and medication history of the selected user is displayed on the time axis. When an image corresponding to the excretion and medication history is selected, information regarding the excretion date and time, defecation, and urination is displayed in a speech bubble format. The defecation record interval in FIG. 6 is information that indicates the time from the most recent defecation to the current time, similar to the defecation interval.

When the image confirmation image 548 is selected, for example, an image of the internal space 34 of the toilet bowl 32 after defecation is displayed. This image is, for example, an image of excrement used in the determination by the determination device 10. By displaying the image, the viewer can once again confirm (confirm) the user's defecation situation.

Image 549 shows details of the medication, such as the name of the drug, the dosage, and the time of administration. Image 549 may also show a message indicating the degree of effect. For example, if the stool excreted after administration is normal or soft, a message stating "The dosage is appropriate" is displayed. If the stool excreted after administration is hard, a message stating "The dosage is slightly insufficient" is displayed. If the stool excreted after administration is muddy or watery, a message stating "The dosage is excessive" is displayed.

As shown in FIG. 7, for example, an image is shown in FIG. 5 or FIG. 6 that displays "aggregated by month" or the like, and when the image is selected, the display unit 54 of the aggregation server 50 displays the user's excretion history in a calendar format. For example, the display unit 54 indicates the number of excretion events for each day on the calendar by the number of images that resemble excreta, and indicates the characteristics by the color and density of the images that resemble excreta.

As shown in FIG. 8, for example, an image is shown in FIG. 5 or FIG. 6 that displays "aggregated by month" or the like, and when the image is selected, the display unit 54 of the aggregation server 50 displays the aggregation results for each characteristic of the excrement for a specified period (here, one month) of the user in a bar graph display mode. The display unit 54 shows the distribution for each characteristic, for example, by placing the characteristic on the horizontal axis and the number of times on the vertical axis.

The process flow in the determination system 1 will be explained with reference to FIG. 9. The determination device 10 acquires image information of an image captured of the internal space of the toilet bowl 32 via the imaging device 4 (step S10). The determination device 10 judges the properties and/or amount of excrement based on the acquired target image (step S11). The determination device 10 outputs the judgment result to the operation terminal 20.

The operation terminal 20 displays the judgment result acquired from the judgment device 10 (step S12). When the operator who has checked the displayed result performs an operation input for confirmation (or correction, etc.), the operation terminal 20 changes the content as necessary according to the operation input content, and confirms the judgment result (step S13). When the operator performs an operation input for user information, the operation terminal 20 acquires the input user information (step S14) and generates excretion information (step S15). The operation terminal 20 notifies the aggregation server 50 of the generated excretion information (step S16).

The aggregation server 50 acquires excretion information that has not been determined by the determination device 10 (in FIG. 9, it is written as "other than the toilet"), that is, generated using the results of a determination made by a person such as a caregiver, at any timing. When the aggregation server 50 acquires excretion information by operation input (step S17), it stores the acquired information in the storage unit 56. When the aggregation server 50 acquires medication information by operation input at any timing (step S18), it stores the acquired information in the storage unit 56. The aggregation server 50 acquires an operation input to display the user's status. In response to the acquired operation input, the display control unit 55 displays the excretion and medication history for each user in chronological order (step S19). For example, when the display control unit 55 acquires an operation input to display a list of the statuses of multiple users, it displays the list shown in FIG. 5, and when, for example, the alert item is touched, the users with an exclamation mark attached to the alert item are sorted and displayed at the top. When the detail image 547 is touched, the display control unit 55 displays the detailed information of the user as shown in FIG. 6.

As described above, the determination system 1 in the first embodiment includes an image information acquisition unit 11 (acquisition unit), a determination unit 13, a control unit 24 (generation unit), and a display control unit 55 (alert control unit). The image information acquisition unit 11 acquires image information of a target image in which excrement is captured. The determination unit 13 determines the properties and/or amount of excrement in the target image. The control unit 24 generates excretion information that associates the determination result in which the properties and/or amount of excrement are determined with user information on the user corresponding to the excrement. The display control unit 55 displays the properties and/or amount of excrement for each user, and when the properties and/or amount of the user's excrement satisfy a predetermined alert condition, alert information indicating that is displayed is notified. In this way, the determination system 1 in the embodiment can notify alert information based on the excretion situation, and if the alert condition is set according to the user, an alert according to the condition can be notified. Therefore, health management based on defecation records can be performed taking into account various circumstances.

The determination system 1 in the first embodiment further includes an input unit 22 (confirmation information input unit). Confirmation information that confirms the determination result determined by the determination unit 13 is input to the input unit 22. The control unit 24 generates excretion information including information indicating whether or not confirmation information corresponding to the determination result determined by the determination unit 13 has been input. In this way, the determination system 1 in the embodiment can display whether or not the determination result by the machine (determination device 10) has been confirmed by a person (operator), and can provide detailed information to viewers viewing the screen of the aggregation server 50.

In the determination system 1 of the first embodiment, the control unit 24 generates the excretion information including information indicating whether or not the determination result in which the properties and/or amount of excrement has been determined has been determined by the determination unit 13. This allows the determination system 1 of the embodiment to display whether the determination result has been made by a machine (determination device 10) or a person (caregiver), and to provide detailed information to the viewer.

In the determination system 1 of the first embodiment, the control unit 24 generates excretion information including information indicating the excretion time when excretion was excreted, and the display control unit 55 displays the presence or absence of excretion for each user in chronological order, and if the elapsed time from the most recent excretion time to the present time is longer than a predetermined threshold, displays alert information indicating this. In this way, the determination system 1 of the embodiment can make the viewer aware of the presence of a user who has not excreted for a long period of time and is prone to constipation.

In the determination system 1 of the first embodiment, the display control unit 55 displays the presence or absence of excretion for each user in chronological order, and when the number of consecutive excretions determined to have a predetermined characteristic is greater than a predetermined number threshold, it displays alert information indicating this. In this way, the determination system 1 of the embodiment can make the viewer aware of the presence of a user who is repeatedly excreting watery stools, etc.

In the determination system 1 of the first embodiment, the display control unit 55 displays the excretion information in a calendar-format display mode. This allows the determination system 1 of the embodiment to visualize the monthly trends of the user, allowing the viewer to recognize the medium- to long-term situation of the user.

The determination system 1 in the first embodiment further includes an input unit 52 (medication information input unit). Medication information related to excretion is input to the input unit 52. This allows the determination system 1 in the embodiment to display the relationship between the amount of medication and the properties of excreta after medication for each user based on the excretion information and medication information.

The aggregation server 50 in the first embodiment includes a communication unit 51 (excretion information acquisition unit) and a display control unit 55 (alert control unit). The communication unit 51 acquires excretion information that associates a determination result of the properties and/or amount of excretion in a target image in which the excretion is captured with user information on the user corresponding to the excretion. The display control unit 55 displays the properties and/or amount of excretion for each user based on the excretion information, and when the properties and/or amount of the user's excretion satisfy a predetermined alert condition, issues alert information indicating that fact. In this way, the aggregation server 50 in the embodiment achieves the same effect as described above.

All or part of the processing performed by the determination system 1 in the above-mentioned embodiment may be realized by a computer. In that case, a program for realizing this function may be recorded in a computer-readable recording medium, and the program recorded in the recording medium may be read into a computer system and executed to realize the function. The term "computer system" here includes hardware such as an OS and peripheral devices. The term "computer-readable recording medium" refers to portable media such as flexible disks, optical magnetic disks, ROMs, and CD-ROMs, and storage devices such as hard disks built into a computer system. Furthermore, the term "computer-readable recording medium" may also include a medium that dynamically holds a program for a short period of time, such as a communication line when a program is transmitted via a network such as the Internet or a communication line such as a telephone line, and a medium that holds a program for a certain period of time, such as a volatile memory inside a computer system that is a server or client in such a case. The above-mentioned program may be a program for realizing part of the above-mentioned function, or may be a program that can realize the above-mentioned function in combination with a program already recorded in the computer system, or may be a program that is realized using a programmable logic device such as an FPGA.

The above describes the embodiment in detail with reference to the drawings. The specific configuration is not limited to this embodiment. For example, instead of display by the display control unit 55, various users may be notified by audio. Alternatively, in addition to display by the display control unit 55, various users may be notified by audio. In this case, the aggregation server 50 has an audio output unit (not shown).
