Description

The present disclosure relates to a determination system.

There is a system to watch over a distant target person by detecting that the toilet has been used. Since defecation is said to reflect the intestinal environment, there are attempts to grasp the health condition based on defecation. It is desirable to be able to grasp the health condition of the person being watched over while watching over.

There are statistics showing that the percentage of elderly people who complain of constipation is high (for example, 2013 National Life Basic Survey, Ministry of Health, Labor and Welfare). As the person being watched over gets older, it is thought that there are many cases of subjective symptoms of constipation. If the person being watched over and his / her family can share whether or not he / she is constipated, the person being watched over can be reassured. For example, in Patent Document 1, the fact that the toilet bowl cleaning operation is performed is regarded as having defecation, and the number of defecations is memorized. A technique for determining the presence or absence is disclosed.

Japanese Unexamined Patent Publication No. 2015-11433

In the technique of Patent Document 1, cleaning of the toilet bowl is regarded as defecation. For this reason, if the toilet bowl cleaning is used even though the patient has not defecated, it is erroneously recognized that the stool has been defecated. Further, in the technique of Patent Document 1, when the number of defecations within the period is equal to or less than the threshold value, it is determined that the patient is constipated. Therefore, there is a problem that when the number of defecations is small but the constipation is not constipated, it is erroneously determined that the patient is constipated.

The present disclosure has been made in view of such circumstances, and an object of the present disclosure is to provide a determination system capable of accurately determining a health condition based on defecation.

In order to solve the above-mentioned problems, one embodiment of the present disclosure is an acquisition unit that acquires start information indicating that the use of the toilet device has been started by a person to be watched over and end information indicating that defecation has been completed. Based on the information acquired by the acquisition unit, the measurement unit that measures the defecation time required for defecation in the monitoring target person, and the target person based on the defecation time measured by the measurement unit. It is a determination system including a determination unit for determining the health condition of the toilet.

Hereinafter, the determination system of the embodiment will be described with reference to the drawings.

As shown in FIG. 1, the determination system 100 includes, for example, a plurality of control units 10 (control units 10-1, 10-2, ..., 10-N) and a plurality of repeaters 20 (repeater 20-1, 20-2, ..., 20-N), an aggregation server 30, and a plurality of user terminals 40 (user terminals 40-1, 40-2, ..., 40-M). N is any integer greater than or equal to 3. M is any integer greater than or equal to 3.

The control unit 10 is connected to the repeater 20. The repeater 20 and the aggregation server 30 are connected via the communication network NW. The aggregation server 30 and the user terminal 40 are connected via the communication network NW. The determination system 100 is not limited to the configuration shown in FIG. The determination system 100 may be configured to include a set of control units 10 and a repeater 20. The determination system 100 may be configured to include a plurality of aggregation servers 30. The determination system 100 may be configured to include one user terminal 40.

As shown in FIG. 2, the control unit 10 of the determination system 100 is provided in the toilet device 1. The toilet device 1 is a toilet having a local cleaning function. The local cleaning function is a function of cleaning a local part of the human body by discharging cleaning water from a nozzle provided on the lower side of the toilet seat 6. The nozzle is housed in the toilet seat box 4. The toilet seat box 4 advances the nozzle to the inside of the toilet body 2 when performing local cleaning, and discharges cleaning water from a discharge hole formed at the tip of the nozzle. The toilet seat box 4 retracts and stores the nozzle in the toilet seat box 4 after local cleaning. This prevents dirt, splashes of washing water, etc. from being applied to the nozzle.

The toilet device 1 includes, for example, a toilet bowl main body 2, a toilet seat box 4, a toilet lid 5, a toilet seat 6, and a motion sensor 7. When the user P of the toilet device 1 is seated on the toilet seat 6, the description will be made with reference to the direction seen from the user P. When viewed from user P, the front side is called "front", the rear side is called "rear", the right side is called "right", and the left side is called "left". The side away from the floor on which the toilet device 1 is installed is called "upper", and the side closer to the floor is called "lower". The user P of the toilet device 1 is an example of a “person to be watched over”.

The toilet seat box 4 is installed on the upper side of the toilet body 2. The toilet seat box 4 communicates with the remote control device 8 and controls the local cleaning function according to a signal from the remote control device 8. The toilet lid 5 and the toilet seat 6 are installed on the upper side of the toilet body 2. The toilet lid 5 and the toilet seat 6 are rotatably supported in the toilet seat box 4 in the vertical direction. The toilet seat box 4 may control the rotation of the toilet lid 5 and the toilet seat 6 according to a signal from the remote control device 8, for example. The remote control device 8 communicates with the toilet seat box 4. The communication method may be wired or wireless. The remote controller 8 is provided with a plurality of operation switches corresponding to toilet bowl cleaning and local cleaning. For example, when the operation switch provided on the remote control device 8 is pressed by the user P, a signal indicating the operation is transmitted from the remote control device 8 to the toilet seat box 4. The toilet seat box 4 performs toilet bowl cleaning and local cleaning according to a signal received from the remote controller 8.

The toilet seat box 4 may control the rotation of the toilet lid 5 based on a signal from a motion sensor provided in the toilet device 1. A motion sensor is a sensor that detects the presence of a person by irradiating infrared rays or the like and receiving the reflected light. The motion sensor is installed, for example, on the front edge of the upper surface of the toilet seat box 4 and detects the presence of a person in front of the toilet body 2. The toilet seat box 4 rotates the toilet lid 5 upward when it is detected by the motion sensor that a person has come in front of the toilet body 2, that is, a person has entered the toilet room. The toilet seat box 4 rotates the toilet lid 5 downward when it is detected by the motion sensor that there is no person in front of the toilet body 2, that is, a person has left the toilet room.

The toilet seat box 4 may control toilet bowl cleaning based on a signal from a seating sensor provided in the toilet device 1. The seating sensor is a sensor that detects a load based on a change in capacitance or the like. The seating sensors are provided on both the left and right sides on the back side of the toilet seat 6, for example, and are installed so as to be sandwiched between the toilet seat 6 and the toilet body 2 when the toilet seat 6 is rotated downward. The seating sensor is sandwiched between the toilet seat 6 and the toilet body 2, and detects the load acting on the toilet seat 6 when the user P is seated. The toilet seat box 4 is used when the seating sensor detects the seating on the toilet seat 6 and then the seating is detected, or when the toilet bowl cleaning is not used between the time when the seating is detected and the time when the seating is detected. , Toilet bowl cleaning. As described above, the toilet bowl cleaning may be executed according to the operation of the remote controller device 8 of the user P, or may be automatically executed by the toilet seat box 4.

The control unit 10 is housed in, for example, the toilet seat box 4. The control unit 10 acquires various signals (hereinafter, referred to as detection signals) detected when the toilet is used, and notifies the repeater 20 of the acquired detection signals. The detection signal is a signal acquired by the toilet seat box 4 for controlling local cleaning and the like, that is, a signal from the remote control device 8, the motion sensor, and the seating sensor (hereinafter, referred to as the remote control device 8 and the like). The control unit 10 acquires a detection signal output from the remote controller 8 or the like via the toilet seat box 4. Alternatively, the control unit 10 may acquire the detection signal directly from the remote controller 8 or the like without going through the toilet seat box 4. The control unit 10 notifies the aggregation server 30 of the information corresponding to the acquired detection signal as the detection result via the repeater 20.

As shown in FIG. 2, the repeater 20 of the determination system 100 is, for example, a mobile information terminal owned by the user P. The repeater 20 may at least be able to relay between the control unit 10 and the aggregation server 30. The repeater 20 may be, for example, a repeater called a GW (gateway) or the like. The communication between the control unit 10 and the repeater 20 is, for example, short-range wireless communication such as Bluetooth (registered trademark) or infrared communication. The communication between the repeater 20 and the aggregation server 30 is, for example, communication using a general-purpose communication network such as the Internet. The repeater 20 includes a short-range wireless communication function for communicating with the control unit 10 and a communication function using the Internet or the like for communicating with the aggregation server 30. When the repeater 20 receives the detection result from the control unit 10, the repeater 20 converts the received detection result into a communication protocol that matches the communication method with the aggregation server 30, and transmits the converted signal to the aggregation server 30.

In the above, the case where the control unit 10 performs communication by the communication method of short-range wireless communication has been illustrated and described. However, it is not limited to this. The control unit 10 may perform communication by any communication method. For example, the control unit 10 may perform communication by a communication method of LPWA (Low Power Wide Area) standard. By suppressing the communication speed, LPWA consumes less power than existing communication networks such as LTE (Long Term Evolution) which is a mobile phone network. The communication distance is large compared to short-range wireless communication such as Bluetooth. In this case, since the communication distance is large, the control unit 10 and the aggregation server 30 can communicate with each other without going through the repeater 20. In this case, the repeater 20 can be omitted.

The aggregation server 30 receives the detection result from the control unit 10 via the repeater 20. The aggregation server 30 determines the health state of the user P based on the detection result received from the control unit 10. The health condition is, for example, either the user P is constipated, diarrhea, or neither constipated nor diarrhea. The method of determining the health condition of the user P based on the defecation time will be described in detail later. The aggregation server 30 notifies the user terminal 40 registered in advance of the determined health state of the user P.

The user terminal 40 is an information terminal having a communication function such as a smartphone, a mobile phone, or a tablet. An application program (hereinafter referred to as an application) of the "watching service" distributed by the aggregation server 30 or the like is installed on the user terminal 40. The user of the user terminal 40 can receive the service by creating an account of the application and registering the person to be watched over. This service is a service that confirms the safety of the person being watched over based on the use of the toilet and notifies the health condition based on the defecation time.

In the above, the case of notifying the safety confirmation and the health condition of the person to be watched through the application of the "watching service" has been described as an example. However, it is not limited to this. The aggregation server 30 may use an existing SNS (Social Networking Service) or the like to confirm the safety of the person being watched over and notify the health condition.

As shown in FIG. 3, the control unit 10 includes, for example, a communication unit 11, an acquisition unit 12, a control unit 13, and a storage unit 14. The communication unit 11 communicates with the repeater 20. The acquisition unit 12 acquires the detection signal. The control unit 13 comprehensively controls the control unit 10. The control unit 13 notifies the repeater 20 of the information corresponding to the detection signal detected by the acquisition unit 12 via the communication unit 11 as the detection result. The acquisition unit 12 and the control unit 13 are realized by causing a CPU (Central Processing Unit) provided as hardware in the control unit 10 to execute a program. The storage unit 14 is configured by arbitrarily combining at least one storage medium. The storage medium is, for example, an HDD (Hard Disk Drive), a flash memory, an EEPROM (Electrically Erasable Programmable Read Only Memory), a RAM (Random Access read / write Memory), and a ROM (Read Only Memory). The storage unit 14 stores a program for executing various processes of the control unit 10 and temporary data used when performing various processes.

As shown in FIG. 4, the aggregation server 30 includes, for example, a communication unit 31, an acquisition unit 32, a measurement unit 33, a determination unit 34, a control unit 35, and a storage unit 36.

The communication unit 31 communicates with the repeater 20 and the user terminal 40. The acquisition unit 32 acquires the detection result received from the control unit 10 via the communication unit 31. The acquisition unit 32 outputs the acquired detection result to the measurement unit 33. The acquisition unit 32 stores the acquired detection result as sensor information 360. The sensor information 360 is information in which the detection result received from the control unit 10 is stored in association with the reception time and the like. The sensor information 360 is stored in, for example, the storage unit 36.

The configuration of the sensor information 360 will be described with reference to FIG. The sensor information 360 includes items such as a date, a seating time, a seating time, a local washing, a toilet bowl washing time, an entry time, and an exit time. The date is the date when the detection result is received from the control unit 10. The seating time is the time when the information indicating that the seating is detected by the seating sensor is received. The seating time is an example of "start information" because it is the time when the person is seated to start using the toilet device 1.

The withdrawal time is the time when the information indicating that the withdrawal is detected by the seating sensor is received. Local cleaning includes items such as start time and end time. The start time is the time when the information indicating that the local cleaning has started is received. The end time is the time when the information indicating that the local cleaning is completed is received. The start time of local washing is an example of "end information" because it is considered that local washing is started after the end of defecation. The end time of the local cleaning is an example of "usage information" because it is information indicating that the local cleaning function has been used.

The toilet bowl cleaning time is the time when information indicating that the toilet bowl cleaning has been performed is received. The entry time is the time when the information indicating that the entry into the toilet room is detected by the motion sensor is received. The exit time is the time when the information indicating that the exit is detected by the motion sensor is received. The entry time is an example of "start information" because it is the time when the user P enters the room to start using the toilet device 1.

Returning to FIG. 4, the measuring unit 33 measures the defecation time based on the sensor information 360. Defecation time is the time required for defecation. The measuring unit 33 considers, for example, the time from the sitting time to the start time of local washing as the defecation time. By considering the start time when local irrigation was used as the end of the defecation time, it is possible to measure only when defecation is performed. Therefore, it is possible to accurately measure the defecation time by excluding cases in which defecation was not performed only by urination or cases in which the patient was just sitting.

In this embodiment, the defecation time is monitored and used as an index of the health condition of the subject. This is because, in general, when the stool to be excreted is hard and constipated, it takes longer to defecate than when the stool is not constipated. That is, the defecation time should be able to be used at least as an index of the health condition. The defecation time may be any time measured based on the sensor information 360. For example, the measuring unit 33 may use the time required from the sitting time to the leaving time as the defecation time, provided that the local washing is used. The measurement unit 33 may use the time required from the time of entering the room to the time of leaving the room as the defecation time, provided that the local cleaning is used. The measuring unit 33 stores the defecation time in the health level information 361. The health level information 361 is information indicating a history of defecation time in the person being watched over and a health condition determined from the history. The health level information 361 is stored in, for example, the storage unit 36.

The configuration of the health level information 361 will be described with reference to FIG. The health level information 361 includes items such as a date, a defecation flag, a defecation time, and a health level. The date is the date when the detection result is received from the control unit 10. The defecation flag is binary information indicating the presence or absence of defecation. For example, the defecation flag is determined depending on whether local washes have been used. In this case, the defecation flag indicates that there is defecation when local irrigation is used and no defecation when local irrigation is not used. The defecation time is the defecation time measured by the measuring unit 33. The health level is the level of the health state determined by the determination unit 34 described later.

Returning to FIG. 4, the determination unit 34 determines the health condition of the monitoring target person based on the defecation time. The determination unit 34 determines that the patient is constipated, for example, when the defecation time is longer than a predetermined threshold value. The determination unit 34 may determine that the patient is constipated when the defecation time is longer than the predetermined threshold value at a predetermined ratio or more (for example, 3 times or more out of 4 times). The determination unit 34 may determine that the patient is constipated when the defecation time is longer than the predetermined threshold value and continues for a predetermined number of times or more.

The determination unit 34 may determine the health state of the person to be watched over at a plurality of levels (hereinafter referred to as health levels). For example, when the defecation time is longer than a predetermined threshold value, the determination unit 34 determines the health level according to the length. When the defecation time is longer than the predetermined threshold value in a predetermined ratio or more, the determination unit 34 may determine the health level according to the ratio. When the case where the defecation time is longer than the predetermined threshold value continues for a predetermined number of times or more, the determination unit 34 may determine the health level according to the number of times. The determination unit 34 stores the health level in the health level information 361.

The control unit 35 comprehensively controls the aggregation server 30. The acquisition unit 32, the measurement unit 33, the determination unit 34, and the control unit 35 are realized by causing a CPU provided as hardware in the aggregation server 30 to execute a program.

The control unit 35 transmits the health level of the monitoring target person determined by the determination unit 34 to the user terminal 40 via the communication unit 11. When transmitting the health level to the user terminal 40, the control unit 35 may change the content to be notified and the notification destination for each health level. For example, when the health level is mild and constipation is present, the control unit 35 notifies only relatives such as family members to that effect. The content of the notification indicates that there is no urgency, and is, for example, a content that notifies that the patient is in a state of mild constipation, that it is not necessary to worry too much, but that it is recommended to call out. When the health level is severely constipated, the control unit 35 notifies not only relatives such as family members but also medical personnel and the like to that effect. The content of the notification indicates that there is an urgency, and is, for example, a content that notifies that the patient is in a severe constipation state and that he / she should see a medical institution immediately.

The control unit 35 determines the notification content and the notification destination with reference to the notification destination information 362, for example, based on the health level determined by the determination unit 34. The notification destination information 362 is information in which the notification content and the notification destination are associated with each other according to the health level. The notification destination information 362 is stored in, for example, the storage unit 36.

The configuration of the notification destination information 362 will be described with reference to FIG. 7. The notification destination information 362 includes items such as health level, notification content, notification destination guideline, notification destination address 1, notification destination address 2, and so on. The health level is the level of health condition determined by the determination unit 34. The content of the notification is a specific content of the notification according to the health level. The notification destination guideline is a notification destination guideline according to the health level. The notification destination guideline indicates, for example, whether or not it is necessary to notify the medical institution. The notification destination address is specific notification destination information for notifying the notification content according to the health level. The notification address includes an e-mail address, an SNS account, and the like.

An example in which the health level is displayed on the user terminal 40 will be described with reference to FIGS. 8 and 9. In this example, the health level of "Mr. A" who is the target person to be watched is notified and displayed on the user terminal 40 of the notification destination. FIG. 8 shows the content of notification for notifying a health level that does not require urgency (for example, health level 1). In this example, the notification "Please take a look at Mr. A at level 1:" is given. FIG. 9 shows the content of the notification for notifying the urgent health level (for example, health level 3). In this example, the notification "Level 3: Please advise Mr. A to go to the hospital" is given.

Returning to FIG. 4, the storage unit 36 is configured by arbitrarily combining at least one storage medium. The storage medium is, for example, an HDD, a flash memory, an EEPROM, a RAM, or a ROM. The storage unit 36 stores a program for executing various processes of the aggregation server 30 and temporary data used when performing various processes. The storage unit 36 stores sensor information 360, health level information 361, and notification destination information 362.

The flow of processing performed by the determination system 100 will be described with reference to FIG. The control unit 10 acquires the start information (step S10). The start information is, for example, the seating information detected by the seating sensor, which indicates that the person to be watched has seated on the toilet seat 6. The control unit 10 transmits the acquired start information to the repeater 20. The repeater 20 relays by transmitting the start information received from the control unit 10 to the aggregation server 30 (step S11). The control unit 10 acquires the end information (step S11). The end information is, for example, usage information indicating that the remote controller 8 is operated by the person to be watched and the local cleaning is started. The control unit 10 transmits the acquired end information to the repeater 20. The repeater 20 relays by transmitting the end information received from the control unit 10 to the aggregation server 30 (step S13). The aggregation server 30 measures the defecation time using the start information and the end information (step S14). The aggregation server 30 stores the measured defecation time in the storage unit 36. The aggregation server 30 performs the processes shown in steps S10 to S15 each time the toilet device 1 is used by the person to be watched over (reference numeral T100).

The aggregation server 30 determines the health level of the person to be watched based on the defecation time or the history of the defecation time (step S16). The aggregation server 30 selects the notification content to be notified to the family of the person to be watched, etc., according to the determined level, using the notification destination information 362 (step S17). The aggregation server 30 notifies the user terminal 40 of the notification content (health level notification). The user terminal 40 receives the health level notification from the aggregation server 30 (step S18). The user terminal 40 displays the received health level notification (step S19).

As described above, the determination system 100 in the embodiment includes an acquisition unit 12, a measurement unit 33, and a determination unit 34. The acquisition unit 12 acquires start information indicating that the use of the toilet device has been started by the person being watched over, and end information indicating that defecation has been completed. The measuring unit 33 measures the defecation time required for defecation by the monitoring target person based on the information acquired by the acquisition unit 12. The determination unit 34 determines the health condition of the monitoring target person based on the defecation time measured by the measurement unit 33. Thereby, the determination system 100 in the embodiment can grasp the start and end of defecation in the person to be watched and measure the defecation time. Therefore, it is possible to determine the health condition based on the defecation time.

In the determination system 100 of the embodiment, the acquisition unit 32 acquires the start information and the end information. Therefore, the determination system 100 can be realized by using the acquisition unit 32 as a component instead of the acquisition unit 12. In this case, the determination system 100 is realized by the aggregation server 30.

In the determination system 100 of the embodiment, the acquisition unit 12 acquires seating information regarding seating on the toilet seat 6 in the toilet device 1 having the local cleaning function and usage information regarding the use of the local cleaning function. As a result, it is possible to measure only when defecation is performed by using the use of local washing as a trigger for measurement. Therefore, it is possible to exclude cases in which the patient did not defecate only by urinating or who was just sitting during the defecation time. It is possible to measure the defecation time more accurately than when the use of local irrigation is not used as a trigger for measurement.

In the determination system 100 of the embodiment, the measurement unit 33 measures the time required from the time when the person to be watched sits on the toilet seat 6 to the start time of local cleaning as the defecation time. This makes it possible to obtain an index that reflects the state of health (particularly the state of constipation). Therefore, it is possible to accurately determine the health condition of the person to be watched over.

In the determination system 100 of the embodiment, the determination unit 34 determines that the subject is in a constipated state when the defecation time is longer than the predetermined time. A storage unit 36 that stores the defecation time measured by the measuring unit 33 is further provided, and the determination unit 34 determines that the defecation time is longer than the predetermined time based on the defecation time stored in the storage unit 36. If it continues for a predetermined number of times or more, it may be determined that the person to be watched is in a constipated state. As a result, the determination system 100 of the embodiment can determine the health state of the person to be watched by simple information processing such as comparison with the threshold value and counting the number of times of continuation.

The determination system 100 in the embodiment further includes a communication unit 31 that transmits the health state of the target person determined by the determination unit 34 to the user terminal 40 registered in advance. As a result, the determination system 100 of the embodiment can make a close person such as a family member recognize the health condition of the person to be watched and share the information. Therefore, it is possible to give a sense of security to the person being watched over and his / her family.

In the determination system 100 of the embodiment, the determination unit 34 determines the health condition by dividing it into a plurality of levels, and the communication unit 31 transmits transmission contents according to the level of the health condition determined by the determination unit 34. .. As a result, the determination system 100 in the embodiment can monitor the health condition of the person to be watched over, and can take measures such as having a medical institution consult when there is an urgent need such as when the patient is in a severe constipation state.

(Modified Example 1 of the Embodiment)
The determination unit 34 may determine not only the defecation time but also the health condition of the watching target person by using the defecation image. The defecation image is an image of the state of the toilet bowl during the defecation time. In this case, the toilet device 1 includes an imaging unit controlled by the control unit 10. The imaging unit is installed, for example, on the back side of the toilet seat 6 so that the internal space of the toilet bowl can be imaged. When the seating sensor detects seating, the control unit 10 causes the imaging unit to take an image at regular intervals (for example, every 1 second). The control unit 10 transmits the image information of the image of the internal space of the toilet bowl to the aggregation server 30 via the repeater 20. The aggregation server 30 receives image information by the communication unit 31.

The determination unit 34 acquires an image of the state of the toilet bowl from the control unit 10 via the communication unit 31. The determination unit 34 determines the health condition of the person to be watched based on the shape and color of the excrement captured in the image. For example, the determination unit 34 analyzes the image using an image processing method to determine whether the excrement is constipated stool (hard stool) or diarrheal stool (diarrheal stool). Judge whether it is normal stool that is neither constipated nor diarrhea. For example, the determination unit 34 determines whether or not the stool is hard by recognizing an object in the image using a machine learning method. Alternatively, the determination unit 34 may determine whether or not the stool is hard stool based on the distribution of brightness obtained from the RGB values of the pixels constituting the image. For example, the determination unit 34 determines that the person to be watched is in a constipated state when the defecation time is longer than a predetermined threshold value and the excrement in the constipated state is imaged in the image.

As described above, in the determination system 100 in the first modification of the embodiment, the determination unit 34 uses the defecation time and the image of the state of the toilet bowl during the defecation time to check the health condition of the person to be monitored. judge. As a result, in the determination system 100 in the first modification of the embodiment, it is possible to accurately determine the health state by performing the determination using not only the defecation time but also the determination result by the image. For example, when the defecation time is long but the normal stool is actually excreted, it is possible to prevent an erroneous determination that the patient is constipated.

(Modification 2 of the embodiment)
The determination unit 34 may determine the health state by using not only the toilet device 1 but also the information excreted by the person to be watched on the go. In this case, the control unit 10 includes an input unit. In the input unit, information (hereinafter, referred to as defecation information) related to excretion on the go, which is operated and input from an input device (for example, a touch panel, operation buttons, etc.), is input. It is desirable that the defecation information includes the sitting time, the start time of local washing, and the like. However, it is not limited to this. The defecation information may be at least information that can determine the health condition, such as whether or not defecation has occurred, the time required for defecation, and whether or not the stool has been hard. The control unit 10 transmits the defecation information input to the input unit to the aggregation server 30 via the repeater 20. Alternatively, when the repeater 20 is an information terminal device such as a smartphone of the person to be watched over, the defecation information may be operated and input to the repeater 20. In this case, the repeater 20 transmits the operation-input defecation information to the aggregation server 30. The aggregation server 30 receives defecation information by the communication unit 31.

The determination unit 34 acquires defecation information via the communication unit 31. The determination unit 34 determines the health condition of the person to be watched over based on the defecation time and the information on the excretion that was out of the office. The determination unit 34 determines that the person to be watched is in a constipated state, for example, when the defecation time is longer than a predetermined threshold value and it is recognized that the person is constipated in the excretion while going out.

As described above, the determination system 100 in the second modification of the embodiment further includes an input unit. In the input unit, defecation information regarding the defecation of the person to be watched when the external toilet is used by the person to be watched is input. The determination unit 34 determines the health condition of the monitoring target person based on the defecation information input to the input unit. As a result, in the determination system 100 in the second modification of the embodiment, it is possible to determine the health condition in consideration of not only the toilet device 1 but also the excretion on the go.

At least a part of the processing performed by the determination system 100 in the above-described embodiment may be realized by a computer. In that case, the program for realizing the function may be recorded on a computer-readable recording medium, and the program recorded on the recording medium may be read by the computer system and executed. The "computer system" here includes hardware such as an OS and peripheral devices. The "computer-readable recording medium" refers to a storage device such as a flexible disk, a magneto-optical disk, a portable medium such as a ROM or a CD-ROM, or a hard disk built in a computer system. Further, a "computer-readable recording medium" is a communication line for transmitting a program via a network such as the Internet or a communication line such as a telephone line, and dynamically holds the program for a short period of time. It may also include a program that holds a program for a certain period of time, such as a volatile memory inside a computer system that is a server or a client in that case. The above program may be for realizing a part of the above-mentioned functions, and may be further realized for realizing the above-mentioned functions in combination with a program already recorded in the computer system, and is an FPGA. It may be realized by using a programmable logic device such as.
