In one embodiment of the present invention, the system functions as an excretion care support system that assists in excretion care for a person who is receiving care.

[0013] In this specification, “excretion” includes at least one of urination or defecation. In this specification, “person receiving assistance” refers to a person who receives assistance with excretion, and includes, for example, a person requiring care, a person requiring support, or an infant wearing a diaper. In this specification, “caregiver” refers to a person who provides assistance with the excretion of a person receiving assistance, and is not particularly limited, but includes, for example, a caregiver, a nurse, or other care helper.

[0014] In this specification, "subject" refers to a person receiving care who is the subject of excretion care in the excretion care support system according to an embodiment of the present invention. In this specification, the user of the excretion care support system includes, for example, a caregiver who provides excretion care to the subject, the subject themselves, and the like.

[0015] In this specification, "absorbent articles for excretion care" refers to articles that are worn by a person being cared for and are capable of absorbing excrement, and examples include urine pads, disposable diapers, cloth diapers, and absorbent auxiliary inner sheets used in combination with urine pads or diapers (for example, "Kasane-de Anshin Sheet" (product name, manufactured by Kao Professional Services Co., Ltd.)). "Absorbent articles for excretion care" will also be referred to as "absorbent articles" below. In one embodiment of the present invention, a person being cared for may use a urine pad in combination with a disposable diaper, a cloth diaper, or the absorbent inner sheet described above. In this case, since the urine pad is placed on the skin side (inside) of the diaper, the disposable diaper or cloth diaper placed on the side relatively farther from the skin (outside) will also be referred to as the "outer layer".

[0016] In this specification, "output" of information includes the transmission of information via the Internet, the transmission of information to other electronic devices using short-range wireless communication or wired communication, and the output of information by a display unit or speaker. Furthermore, in this specification, "acquisition" of information includes the reception of information via the Internet, the reception of information from other electronic devices using short-range wireless communication or wired communication, the acquisition of information received through user input operations, and the acquisition of information stored in a memory unit or external memory device.

[0017] The embodiments for carrying out the present invention will be described in detail below with reference to the drawings. However, the configuration, numerical values, processing flow, and functional elements described in the following embodiments may differ. These are merely examples, and modifications and changes are permitted. The technical scope of this invention is not limited to the following description. This is not intended to define a system. In this specification, "system" includes one or more information processing devices. For example, a single information processing device can constitute a system, and multiple information processing devices can also constitute a system when they cooperate to perform functions such as a web server. Furthermore, as described in the following embodiments, "system" may include one or more information processing devices that function as a web server and one or more terminal devices.

[0018] <First Embodiment> [System Configuration] As illustrated in Figure 1, a system according to the first embodiment of the present invention includes, for example, a server 100 on the Internet N, a user terminal 200, and a sensor device 50. The server 100 is connected to the user terminal 200 and the sensor device 50 via the Internet N. Although Figure 1 shows an example in which the system includes one user terminal 200, it may include multiple user terminals 200. Similarly, although Figure 1 shows an example in which the system includes one sensor device 50, it may include multiple sensor devices 50.

[0019] Server 100 can be, for example, a web server (information processing device) operated by an operator of an excretion care support service that provides assistance with excretion care to a person. The excretion care support service may be, for example, a service that provides assistance with excretion care to a person receiving care. Server 100 can process information input from, for example, the user terminal 200 and the sensor device 50, and provide the excretion care support service to the user using the user terminal 200 via an application program or website, etc.

[0020] The user terminal 200 may be, but is not limited to, a smartphone, desktop PC, notebook PC, tablet PC, or smartwatch. For example, the user terminal 200 accesses the server 100, receives a web page or the like generated by the server 100, and displays it on the screen using a browser or the like.

[0021] In this embodiment, the sensor device 50 is placed on the urine pad 11, which is an absorbent article. As illustrated in Figure 1, the sensor device 50 includes, for example, a wetness detection sensor 20 capable of detecting wetness of the urine pad 11, and a sensor body 30 including an acceleration sensor 34 (see Figure 6). The sensor device 50 transmits, for example, data based on the output of the wetness detection sensor 20 and data based on the output of the acceleration sensor 34 to the server 100 via the internet N.

[0022] [Hardware configuration of information processing equipment] As shown in Figure 2(A), the server 100 includes, for example, a CPU (Central Processing Unit) 101, a ROM (Read Only Memory) 102, a RAM (Random Access Memory) 103, an input / output interface 105, and a bus 104 that connects these to each other.

[0023] The CPU 101 is a processor that comprehensively controls all blocks of the server 100 while performing various calculations by appropriately accessing RAM 103 and other memory as needed. ROM 102 is a non-volatile memory in which the OS, programs, and firmware such as various parameters to be executed by the CPU 101 are permanently stored. RAM 103 is used as a working area for the CPU 101 and temporarily holds the OS, various running application programs, and various data being processed.

[0024] The input / output interface 105 is connected to the display unit 106, the operation reception unit 107, the storage unit 108, the communication unit 109, and the like.

[0025] The display unit 106 is a display device that uses, for example, an LCD (Liquid Crystal Display), an OLED (Organic ElectroLuminescence Display), or a CRT (Cathode Ray Tube).

[0026] The operation reception unit 107 is, for example, a pointing device such as a mouse, a keyboard, a touch panel, or other input device. If the operation reception unit 107 is a touch panel, the touch panel may be integrated with the display unit 106.

[0027] The storage unit 108 is a non-volatile memory such as an HDD (Hard Disk Drive), flash memory (SSD; Solid State Drive), or other solid-state memory. The OS, various application programs, and various data are stored in this storage unit 108.

[0028] In this embodiment, the storage unit 108 may have, in addition to programs necessary for the processing described later, a target information database, a reference information database, and other databases used for processing, as described later. Databases such as the target information database are referenced as needed during system processing. These databases may be stored in a storage device or server externally connected to the server 100, rather than in the storage unit 108.

[0029] The communication unit 109 consists of various modules for wireless communication, such as a NIC (Network Interface Card) for Ethernet or a wireless LAN, and is responsible for communication processing between the user terminal 200 and the sensor device 50.

[0030] As shown in Figure 2(B), the user terminal 200, like the server 100, includes, for example, a CPU 201, ROM 202, RAM 203, bus 204, input / output interface 205, display unit 206, operation reception unit 207, storage unit 208, and communication unit 209. Furthermore, the user terminal 200 may also have an imaging unit 210, which may consist of a camera or the like.

[0031] [Configuration of sensor device and absorbent article] First, the basic configuration of the urine pad 11 and disposable diaper 12 on which the sensor device 50 is placed will be described. The disposable diaper 12 will be referred to as "diaper 12" below.

[0032] As illustrated in Figure 3, the urine absorption pad 11 is placed on the skin-facing side of the diaper 12. In this specification, "skin-facing side" refers to the side of each component of the urine absorption pad 11 and the diaper 12 that is placed on the skin side of the wearer when worn. "Non-skin-facing side" refers to the side of each component of the urine absorption pad 11 and the diaper 12 that is placed on the side opposite to the wearer's skin (the clothing side) when worn.

[0033] In this embodiment, the diaper 12 is configured as a so-called unfoldable (tape-type) diaper. The diaper 12 is divided into a ventral region A that is positioned on the wearer's abdominal side when worn, a dorsal region B that is positioned on the wearer's back side when worn, and a crotch region C positioned between the ventral region A and the dorsal region B. In the diaper 12, the direction extending from the ventral region A through the crotch region C to the dorsal region B is defined as the "longitudinal direction Y," and the direction perpendicular to the longitudinal direction Y and corresponding to the wearer's left-right direction is defined as the "width direction X."

[0034] As illustrated in Figure 3, the diaper 12 includes, for example, a surface sheet 12a that forms the skin-facing surface and on which a urine absorption pad 11 is placed, a back sheet 12b that is placed on the non-skin side, and an absorbent material 12c that is placed between the surface sheet 12a and the back sheet 12b. Furthermore, the diaper 12 has, for example, a leg gather 12d that is placed on the widthwise X-side edge of the crotch region C and formed by the contraction of an elastic member. Furthermore, the diaper 12 has, for example, a fastening tape 13 that is placed on the widthwise X-side of the dorsal region B and fastened to the non-skin-facing surface of the ventral region A. Each component of the diaper 12 may be made of a material usable in the field of absorbent articles.

[0035] The composition of the diaper 12 is not limited to this, and it may also be a disposable diaper of the pull-up type. Furthermore, the object on which the urine absorption pad 11 is placed is not limited to disposable diapers, but may also be a cloth diaper or cloth pull-up pants, etc.

[0036] As illustrated in Figures 3 to 5, the urine absorption pad 11 includes, for example, a surface sheet 11a that forms the skin-facing surface, a back sheet 11b that forms the non-skin-facing surface, and an absorbent material 11c disposed between the surface sheet 11a and the back sheet 11b. The urine absorption pad 11 extends in the longitudinal direction Y overall. Each component of the urine absorption pad 11 may be made of a material usable in the field of absorbent articles.

[0037] As illustrated in Figures 1 and 4, the sensor device 50 is positioned, for example, on the non-skin-facing surface (back sheet 11b) of the urine pad 11 and between the urine pad 11 and the diaper 12. The sensor device 50 includes, for example, a wetness detection sensor 20, a sensor body 30, and a covering sheet 27. The sensor device 50 may, but is not limited to, the configuration described in, for example, Japanese Patent Application Publication No. 2022-89214.

[0038] As illustrated in Figures 4 and 5, the wetness detection sensor 20 includes, for example, a plurality of printed electrodes 21, a plurality of conductive wires 23, and a terminal 24. The wetness detection sensor 20 can detect wetness and wet areas of the urine pad 11 based on impedance changes between the plurality of printed electrodes 21. Note that the configuration of the printed electrodes 21, conductive wires 23, and terminal 24 is not limited to the illustrated examples.

[0039] Multiple printed electrodes 21 are arranged on the non-skin-facing surface of the urine pad 11. The printed electrodes 21 may have a conductive configuration and may include, for example, an insulating printing substrate 22 and conductive ink coated on the printing substrate 22. Multiple printed electrodes 21 may include, for example, multiple positive electrodes 21a and multiple negative electrodes 21b. Multiple positive electrodes 21a and multiple negative electrodes 21b are arranged on the right and left sides in the width direction X, and alternately along the longitudinal direction Y. In addition, ventilation openings 25 where no electrodes are formed may be formed between the positive electrodes 21a and the negative electrodes 21b. In this embodiment, each printed electrode 21 (each of the multiple positive electrodes 21a and multiple negative electrodes 21b) is also referred to as a sensor element 20a.

[0040] The conductor portion 23 electrically connects the multiple printed electrodes 21 and the terminal portion 24. The conductor portion 23 includes, for example, a conductor portion 23a connected to the multiple positive electrodes 21a and the first terminal 24a of the terminal portion 24 and extending along the longitudinal direction Y, a conductor portion 23b1 connected to the multiple negative electrodes 21b and extending along the longitudinal direction Y, and a conductor portion 23b2 connected to the conductor portion 23b1 and the second terminal 24b of the terminal portion 24 and extending along the width direction X. The conductor portion 23, like the printed electrodes 21, is formed by a printed conductive layer 28 made of conductive ink applied to the surface of the printed substrate 22.

[0041] The terminal section 24 includes, for example, a first terminal 24a connected to the positive electrode 21a and a second terminal 24b connected to the negative electrode 21b. The first terminal 24a and the second terminal 24b may be configured as conductive terminals that can engage with the sensor body 30, but in the illustrated example, they are configured as snap buttons made of a conductive material that can engage with a part of the sensor body 30. In addition to snap buttons, the first terminal 24a and the second terminal 24b may also be made of conductive connectors, wire fasteners, hook-and-loop fasteners, screws, hooks, snap fasteners, etc.

[0042] The covering sheet 27 covers the printed electrode 21 and the conductive wire portion 23 from the non-skin side. The covering sheet 27 is bonded to the back sheet 11b of the urine pad 11 by adhesive 26 applied in an arbitrary shape (spiral shape in the illustrated example) so as to sandwich the printed electrode 21 and the conductive wire portion 23. The area of ​​the covering sheet 27 where adhesive 26 is not applied is designated as the non-adhesive area 26a. The covering sheet 27 can be made of any insulating sheet material, such as nonwoven fabric or a resin film. Although not shown in the illustration, the covering sheet 27 has through holes to expose the terminal portion 24.

[0043] As illustrated in Figure 6, the sensor body 30 includes an impedance detection unit 31, a data logger 32 that records impedance change data detected by the impedance detection unit 31, a timer 33 that outputs time data, an acceleration sensor 34 that detects tilt and motion, a communication unit 35, and a microcontroller 36.

[0044] The impedance detection unit 31 applies a voltage to the entire circuit of the wetness detection sensor 20 to detect changes in impedance. Specifically, as shown in Figure 6, the impedance detection unit 31 includes an oscillator 31a that oscillates a predetermined frequency signal, an impedance change detection circuit 31b that uses the frequency signal from the oscillator 31a to detect the total amount of impedance change of a plurality of sensor elements 20a, and an impedance change voltage conversion unit 31c that converts the total amount of impedance change detected by the impedance change detection circuit 31b into voltage change data. The voltage change data generated by the impedance change voltage conversion unit 31c is output to the data logger 32. In this embodiment, the "voltage change data acquired from the impedance detection unit 31" is referred to as "data based on the output of the wetness detection sensor 20".

[0045] The acceleration sensor 34 is preferably composed of a three-axis acceleration sensor. The three-axis acceleration sensor detects data in the X-axis, Y-axis, and Z-axis directions related to the tilt and movement of the absorbent article to which the sensor is attached, and outputs these data to the data logger 32 along with the time data output from the timer 33. The data output by the acceleration sensor 34 is referred to as "data based on the output of the acceleration sensor 34".

[0046] The data logger 32 records data based on the output of the wetness detection sensor 20 and data based on the output of the acceleration sensor 34, associating them with time data output from the timer 33.

[0047] The microcontroller 36 has, for example, a CPU, RAM, ROM, and input / output ports, and functions as a control unit (processor) for the sensor body 30.

[0048] The communication unit 35 is configured, for example, as various modules for wireless and / or wired communication. Based on the control of the microcontroller 36, the communication unit 35 outputs the data recorded in the data logger 32, associating it with the identification information (such as the sensor ID) of the sensor device 50.

[0049] In the sensor device 50 with the above configuration, a wetness detection sensor 20 is placed on the back sheet 11b of the urine collection pad 11. The wetness detection sensor 20 and the sensor body 30 are connected by engaging the terminal portion 24 of the wetness detection sensor 20 with the sensor body 30. When replacing the urine collection pad 11, the caregiver separates the terminal portion 24 and the sensor body 30 on the used urine collection pad 11 and engages the sensor body 30 with the terminal portion 24 of the new urine collection pad 11. This allows data output to be performed using the same sensor body 30 even after replacing the urine collection pad 11.

[0050] [Example of database configuration] As illustrated in Figure 7, in this embodiment, the storage unit 108 of the server 100 stores a target information database 108a, a reference information database 108b, and a user information database 108c.

[0051] The target information database 108a stores profile information and other information for each target person who has registered for the excretion care support service.

[0052] The subject's profile information includes not only attribute information but also physical information indicating their physical condition. Attribute information is not limited to, but may include, for example, the subject's name (nickname), an ID to identify the subject, the subject's affiliation (name of the facility receiving care, facility ID, etc.), age, and gender. Physical information includes weight, height, level of care required, level of independence in daily living, basic motor skills (ADL; Activities of Daily Living), severity and location of paralysis, severity and location of contractures, location and symptoms of skin problems, speech ability, presence or absence of urinary urge, medical history, medications being taken, and other information about the body.

[0053] Furthermore, the subject information database 108a stores, for each subject, item information about the absorbent articles (absorbent articles) used for excretion care, and status information for at least one situation selected from the subject's excretion status, activity status, and sleep status, all associated with time information. In this embodiment, this information includes information acquired from the user terminal 200 and the sensor device 50.

[0054] In this specification, "time information" refers to information that includes the concept of time, such as periods, dates, dates and times, and dates and time zones (for example, time zones divided into units of time such as 15 minutes, 30 minutes, or 1 hour, or time zones such as daytime / nighttime). Furthermore, time information associated with multiple pieces of information only needs to indicate a common timing among these pieces of information, and the way it is represented may differ.

[0055] The item information includes, for example, identification information (product name, product ID, etc.) that identifies the absorbent item used by the subject. Furthermore, the item information may also include the type of absorbent item (urine pad, diaper, etc.), the type of diaper (pants type, pull-up type, etc.), information on absorption capacity (absorption capacity, number of times urine is absorbed, etc.), the time of day (day, night, etc.), size, etc., which are associated with the identification information. From the viewpoint of efficiently reducing the risk of leakage of excrement, it is preferable to include at least one piece of information selected from the type of absorbent item, information on absorption capacity, and size. If the subject uses both a urine pad and a diaper, it is preferable for the item information to include information about the urine pad and information about the diaper, respectively.

[0056] The situational information preferably includes, from the viewpoint of efficiently reducing the risk of leakage of excrement, an event indicating at least one situation selected from the subject's excretion status, activity status, and sleep status, a response to that at least one situation, and at least one piece of information selected from the evaluation results for that at least one situation. Furthermore, the situational information may also include other information about that at least one situation. In this specification, activity status mainly refers to daytime activity status and excludes excretion status and sleep status.

[0057] The information about excretion status included in the status information includes data showing the excretion status and processed information therefrom, evaluation results regarding the excretion status, events indicating the excretion status, countermeasures for the excretion status, and other information regarding the excretion status. Specific examples of information about excretion status include data based on the output of the wetness detection sensor 20, data based on the output of the acceleration sensor 34, processed information from this data, timing and frequency of changing urine pads, timing and frequency of changing diapers, presence and type of assistance when changing absorbent items, location of changing absorbent items, timing and frequency of toilet guidance, timing and frequency of urination in the toilet, timing and frequency of defecation in the toilet, frequency of urination, frequency of defecation, timing, number and amount of urine leakage, presence or absence of urge to urinate, presence or absence of verbal or physical complaints regarding excretion, characteristics of stool, timing and frequency of fecal leakage, measurement results of urine volume (average urine volume, total urine volume per day, etc.), and residual urine measurement results. Information about the excretion status may include, for example, sensor information obtained from the sensor device 50, information obtained from the user terminal 200, and information obtained from other monitoring devices. By analyzing information about the subject's excretion status, it is possible to derive the risk of leakage of the subject's excrement.

[0058] The activity status information included in the status information refers to activity status during times other than bedtime (e.g., during the day), and includes data indicating activity status, processed information therefrom, evaluation results of other activity status, events indicating activity status, and measures to improve activity status. Specific examples of activity status information include the timing and frequency of fluid intake, the amount of fluid intake, the type of beverage consumed, the timing and frequency of meals, the amount of food eaten, the timing of bathing, daytime posture, number of steps, energy expenditure, daytime vital data (heart rate, blood pressure, blood oxygen level, etc.), timing, type and frequency of exercise, timing, type and frequency of massage, and the type and amount of other activities. Activity status information may also include, for example, information acquired from the user terminal 200, as well as data acquired from other monitoring devices (activity trackers, pedometers, motion sensors, blood pressure monitors, and other portable information terminals such as smartphones and smartwatches equipped with application programs capable of monitoring vital data and activity data). By analyzing information about the subjects' activity levels, it is possible to derive the risk of leakage of excrement based on the subjects' movements and physical condition.

[0059] The information about sleep status included in the situational information includes data indicating sleep status and processed information therefrom, other evaluation results regarding sleep status, events indicating sleep status, and measures to improve sleep status. Examples of information about sleep status include bedtime, wake-up time, sleep duration, timing and number of awakenings during sleep, REM sleep duration, vital data such as heart rate, blood pressure, and blood oxygen level during sleep, respiratory rate, and electroencephalogram (EEG). Information about sleep status may also include information acquired from other monitoring devices (such as motion sensors, blood pressure monitors, and mobile information terminals such as smartphones and smartwatches equipped with application programs capable of monitoring vital data and sleep data). By analyzing information about the subject's sleep status, it is possible to derive the risk of excretory leakage of the subject based on the subject's movements and physical condition during sleep.

[0060] In this embodiment, the subject information database 108a preferably includes, for each subject, an item record that records item information over time and a situation record that records situation information over time, from the viewpoint of supporting the independence of the person being assisted in more efficient excretion. This allows the absorbent items used and the corresponding situation information to be associated with time information. In this specification, "information recorded over time" means information that is stored in association with time information for a certain period of time.

[0061] Furthermore, in this embodiment, the subject information database 108a may store issues related to excretion care for each subject. Issues related to excretion care may be issues transmitted from the user terminal 200 as part of the profile information, or issues generated by the server 100. Alternatively, the subject information database 108a may store information on recommended means to prevent leakage of excrement, generated by the server 100, for each subject. Furthermore, it is preferable that the above-mentioned issues and recommended means information are stored in association with time information. This makes it possible to understand the timing of the setting of each issue and recommended means.

[0062] The reference information database 108b stores reference information that will be referenced in the processing described later. The reference information includes sample item information for each of a plurality of absorbent items associated with the degree of independence of the person being cared for, and sample situation information for at least one situation selected from the excretion status, activity status, and sleep status of the person being cared for, which is associated with each of the plurality of absorbent items.

[0063] The sample item information includes, for each absorbent item, identification information (product name, product ID, etc.) and information representing the degree of independence of the person receiving care who will be using the product. In this specification, "degree of independence of the person receiving care" means the degree of independence of the person receiving care in daily life, including excretion. Information representing the degree of independence of the person receiving care may include, for example, information that directly represents the degree of independence of the person receiving care, and other information related to the degree of independence of the person receiving care (e.g., diaper type, absorption capacity, etc.). Information that directly represents the degree of independence of the person receiving care may include, for example, words that represent independence ("can go out alone," "can walk alone," "can walk with assistance," "can stand and sit with assistance," "spends most of their time lying down," etc.), paraphrases of the words that represent independence expressed by numbers (1, 2, etc.) or symbols. Information related to the degree of independence of the person receiving care may include information on absorption capacity (absorption capacity, number of times urine is absorbed, etc.) and diaper type (pants type, pull-up type, cloth diaper, etc.). Furthermore, the amount absorbent material absorbs tends to decrease as the corresponding level of independence increases. Generally, the types of diapers are targeted at care recipients with increasing levels of independence, in the order of tape-type disposable diapers, pull-up type disposable diapers, and cloth diapers (cloth pull-ups). In addition, sample item information may include, for each absorbent item, the type of absorbent material (urine pad, disposable diaper, etc.), the time of day it is intended for, the available sizes, the gender it is intended for, etc.

[0064] From the perspective of supporting the independence of the person being cared for in more efficient excretion, the sample situation information preferably includes an event indicating at least one situation selected from the person being cared for's excretion status, activity status, and sleep status associated with each absorbent item, the response to that at least one situation, and at least one piece of information selected from the evaluation results for that at least one situation, and more preferably includes all of the information. Furthermore, the sample situation information may also include other information related to that at least one situation. Specific examples of sample situation information include information similar to the situation information described above.

[0065] In this embodiment, the reference information database 108b preferably includes, from the viewpoint of supporting the independence of the person being cared for in more efficient excretion, a sample item record that records sample item information over time for each of several sample subjects who are cared for by different persons than the subject, and a sample situation record that records sample situation information for each of the multiple sample subjects, which is associated with the sample item record. In this specification, a sample subject refers to a person being cared for by different persons than the subject, who is the subject of the data included in the reference information. In other words, the reference information preferably includes a sample item record corresponding to the item record and a sample situation record corresponding to the situation record for each of the multiple cared-for persons who are different from the subject.

[0066] Furthermore, in this embodiment, it is preferable that the reference information database 108b stores profile information for each sample subject. The profile information of a sample subject may include information similar to the information exemplified as the subject's profile information, but it does not have to include information that identifies the individual sample subject (e.g., name, contact information, affiliation, etc.).

[0067] The user information database 108c stores attribute information for each user registered with the excretion care support service. User attribute information is not particularly limited, but may include general information such as the user's name (nickname), user identification ID, user affiliation (facility name, facility ID, type of facility, facility address, etc.), user contact information, and identification information of the person the user is responsible for assisting.

[0068] [Example of system operation] Next, an example of the operation of the system in this embodiment will be described. The operation of the server 100 described below is performed by the cooperation of hardware such as the CPU 101 and the communication unit 109 and the software stored in the storage unit 108. Similarly, the operation of the user terminal 200 is performed by the cooperation of hardware such as the CPU 201 and the communication unit 209 and the software stored in the storage unit 208. The operation of the sensor device 50 is performed by the microcontroller 36.

[0069] In this example, the subject is a care recipient who uses absorbent items (urine pads and diapers), and the user using user terminal 200 is the caregiver of the subject. The user is assumed to have registered with the excretion care support service in advance.

[0070] In this example, the reference information database 108b includes a sample item record and a sample status record for each of the multiple sample subjects. The sample status record includes records of the same type as the subject's first and second status records described later.

[0071] First, the user logs in to the internet site or application program provided by the excretion care support service. Then, as illustrated in Figure 8, the CPU 201 of the user terminal 200 sends a request to submit the questionnaire form based on the user's input (S201). The CPU 101 of the server 100 receives (acquires) the request to submit the questionnaire form (S101) and sends the questionnaire form to the user terminal 200 (S102). The CPU 201 of the user terminal 200 receives the questionnaire form (S202) and displays the questionnaire form on the display unit 206 (S203).

[0072] Figure 9 shows an example of a questionnaire form displayed on the display unit 206. In this example, the questionnaire form 400 includes multiple item fields 401 and input fields 402. The item fields 401 include, for example, the date of completion, the user's identification information, the subject's identification information, age, gender, weight, level of care required, cognitive / independence level, presence and location of paralysis, presence and location of contractures, presence, location and symptoms of skin problems, medical history, medications being taken, physical characteristics, etc. Furthermore, the item fields 401 include items regarding the excretion status at the time of filling out the input form 400, such as presence or absence of urge to urinate, presence or absence of verbal / complaints about excretion, presence or absence of diaper use, type of diaper used as an outer layer during the day, type of diaper used as an outer layer at night, type of incontinence pad, comments regarding the use of incontinence pads, location of diaper changes during the day and night, and circumstances during excretion. The input fields 402 may be configured to allow the user to select an answer from a set of options for each item, or they may allow the user to freely enter an answer.

[0073] The CPU 201 of the user terminal 200 receives input to the questionnaire form 400 (S204) and sends the entered questionnaire information to the server 100 (S205). The server 100 receives (acquires) the questionnaire input information (S103) and stores the questionnaire input of the subject in the subject information database 108a (not shown). In this example of operation, the questionnaire input information includes profile information of the subject, including attribute information and / or physical information.

[0074] The CPU 101 of the server 100 sends the input forms for item records and status records to the user terminal 200 (S104). Hereinafter, the input forms for item records and status records will be referred to as the "record input form". The CPU 201 of the user terminal 200 receives the record input form (S206) and displays the record input form on the display unit 206 (S207).

[0075] Figure 10 shows an example of a record input form. The record input form 500 illustrated in the figure includes, for example, a subject ID input field 501, a sensor unit ID input field 502, a recording period input field 503, a fluid intake record input field 504, a toilet guidance record input field 505, a pad change record input field 506, an outer input field 507, a bowel movement record input field 508, and a bathing record input field 509. The fluid intake record input field 504 allows input of, for example, the time of fluid intake and the amount of fluid intake. The toilet guidance record input field 505 allows input of, for example, the time of guidance to the toilet, whether or not urination occurred in the toilet, and whether or not urine was measured in the toilet. Note that "urine measurement" in the toilet guidance record input field 505 refers to, for example, measuring the amount of urine collected in a urine collection device in the toilet. The toilet guidance record input field 505 may also record the amount of water absorbed by the diaper and the amount of urine in the toilet (not shown). The pad change record input field 506 allows you to input, for example, the time and type of urine pad to be changed, and the procedures taken at the time of change. Note that "urine measurement" in the pad change record input field 506 refers to measuring the amount of water absorbed by the urine pad. The outer input field 507 allows you to input the type of diaper used as the outer layer. The bowel movement record input field 508 allows you to input whether or not there was a bowel movement, the time of the bowel movement, and the consistency of the stool. The bathing record input field 509 allows you to input whether or not there was a bath and the time of the bath.

[0076] The user, for example, decides on any four days as the first target period and enters information into the record input form 500 during the first target period. The CPU 201 of the user terminal 200 receives the input into the record input form 500 (S208) and, based on input operations such as the send button (not shown), sends the input information from the record input form 500 to the server 100 (S209). The CPU 101 of the server 100 receives (acquires) the input information from the record input form 500 (S105) and stores the input information in the target person information database 108a of the storage unit 108 (not shown).

[0077] Meanwhile, during the first target period, the subjects use a urine collection pad 11 on which the sensor device 50 is placed. The sensor body 30 is removed from the used urine collection pad 11 each time the urine collection pad 11 is replaced and engaged with the terminal portion 24 of the new urine collection pad 11.

[0078] The microcontroller 36 of the sensor body 30 controls the data logger 32 to record data based on the output of the wetness detection sensor 20 and data based on the output of the acceleration sensor 34 in association with time (S301), and controls the communication unit 35 to transmit sensor information, including the data based on the output of the wetness detection sensor 20 and the data based on the output of the acceleration sensor 34, which is associated with time, in association with the identification information of the sensor body 30 (S302). The microcontroller 36 may transmit the data directly to the server 100 via the internet N, or it may transmit the data to the user terminal 200 by wired or wireless connection and then transmit the data to the server 100 via the user terminal 200.

[0079] The CPU 101 of the server 100 receives (acquires) sensor information (S106) and stores it in the subject information database 108a of the storage unit 108 (not shown). In this example of operation, the CPU 101 that receives the sensor information compares the identification information of the received sensor body 30 with the identification information of the sensor body 30 entered in the record input form 500, and stores the sensor information in the subject information database 108a corresponding to the subject ID entered in the record input form 500.

[0080] Furthermore, the CPU 101, upon receiving sensor information, can generate a record of the wetness and amount of wetness of the urine pad (absorbent article) associated with time, based on data derived from the output of the wetness detection sensor 20. Specifically, the CPU 101, referring to Japanese Patent Application Publication No. 2022-89214, detects the wetness and its spread (amount of wetness) of the urine pad 11 at each time based on impedance changes detected by sensor elements 20a placed at various positions on the urine pad 11. As a result, the CPU 101 can store the record of the wetness and amount of wetness of the urine pad 11 associated with time in the subject information database 108a as part of the first status record.

[0081] Similarly, the CPU 101, upon receiving sensor information, can generate a record of the tilt of the urine pad (absorbent item) associated with time, based on data derived from the output of the acceleration sensor 34. Specifically, the CPU 101 can detect the tilt of the sensor body 30 in the X, Y, and Z axes while it is attached to the urine pad 11, based on data derived from the output of the acceleration sensor 34. The tilt of the sensor body 30 corresponds to the posture of the person wearing the urine pad 11 (sitting, lying on their back, lying on their side, etc.). Therefore, the CPU 101 can generate a record of the person's posture associated with time, based on data derived from the output of the acceleration sensor 34, referring to Japanese Patent Application Publication No. 2022-89214. Furthermore, the CPU 101 can measure the amount of change in the tilt of the sensor body 30 per unit time from data derived from the output of the acceleration sensor 34, referring to the above-mentioned document, and detect the movement of the urine pad 11 based on this change in tilt. This allows the CPU 101 to generate a record of the movement (position shift) of the urine collection pad 11, which is associated with the time. These records generated by the CPU 101 can be stored in the subject information database 108a, for example, as part of the first situation record.

[0082] Here, the first subject information includes first item information about absorbent articles used by the subject during the first target period, and first situation information about at least one situation selected from the subject's excretion status, activity status, and sleep status during the first target period. In this embodiment, the first subject information includes a first item record that records the first item information over time, and a first situation record that records the first situation information over time. That is, in this example of operation, the input information of the record input form 500 for the first target period and the sensor information for the first target period are included in the first item record and the first situation record of the first subject information. Specifically, the first item record includes the type of urine pad and the time of its replacement based on the input information of the pad replacement record input field 506 of the record input form 500, and the types of diapers used during the day and at night based on the input information of the outer input field 507. The first status record includes a record based on the output of the wetness detection sensor 20 and the output of the acceleration sensor 34 included in the sensor information, the time and amount of water intake based on the input information in the water intake record input field 504 of the record input form 500, the time of toilet guidance, whether or not urination occurred in the toilet and whether or not urine was measured based on the input information in the toilet guidance record input field 505, a record of defecation based on the input information in the defecation record input field 508, and whether or not bathing occurred and the time of bathing based on the input information in the bathing record input field 509.

[0083] Therefore, in this example of operation, the step S105 for acquiring input information from the record input form (during the first target period) and the step S106 for acquiring sensor information function as the "first target information acquisition step". In addition, in S105 and S106, the CPU 101 functions as the "first target information acquisition unit".

[0084] Next, the CPU 101 of the server 100 extracts absorbent articles and / or circumstances related to the risk of leakage of the subject's excrement from the first subject information, and generates a first recommended means for preventing leakage of excrement based on the reference information related to the extracted absorbent articles and / or circumstances (S107). In this step, the CPU 101 functions as a "first recommended means generation unit".

[0085] Figure 11 is an example of a daily first status record 600 generated from the input information of the record input form 500 and sensor information during the first target period. In the first status record 600 of Figure 11, the "Drinking Water" item indicates the time of water intake, the "Bathing" item indicates the time of bathing, the "Defecation" item indicates the time of defecation, the "Toilet etc." item indicates the time of toilet guidance, the "Change / Urine Measurement" item indicates the time of urine pad change and urine measurement, the "Wetness" item indicates the time of wetting of the urine pad and the amount of wetting based on the output of the wetness detection sensor 20, and the "Tilt" item indicates the frequency of tilt (posture) and movement (position displacement) of the absorbent item based on the output of the acceleration sensor 34. In each item, the filled-in time period indicates that the event corresponding to that item occurred. In the "Wetness" item, the darkly filled-in time period indicates that the amount of wetting (amount of wetting spread) was relatively high, and the lightly filled-in time period indicates that the amount of wetting (amount of wetting spread) was relatively low. In the "Tilt" section, "Left" indicates that the subject and absorbent material are facing left, "Front" indicates that the subject and absorbent material are facing forward, and "Right" indicates that the subject and absorbent material are facing right. In the "Tilt" section, darkly colored time periods indicate a relatively high frequency of movement and positional displacement, while lightly colored time periods indicate a relatively low frequency of movement and minimal positional displacement. Furthermore, in the "Tilt" section, it is preferable that postures with the head raised (standing or sitting) and postures with the legs raised (lying down) are represented by different colors.

[0086] In step S107 of this example, the CPU 101 first extracts, for example, time periods with a high risk of excrement leakage (hereinafter referred to as "high-risk time periods") from the first subject information.

[0087] For example, the CPU 101 can extract timings where the frequency and / or amount of wetness of the urine pad detected based on the output of the wetness detection sensor 20 is relatively high, for instance, as high-risk time periods. Examples of comparison targets for the frequency and / or amount of wetness of the urine pad include data from different days at the same time during the first target period, or data on the average frequency and / or amount of wetness of the urine pad at the same time period stored in the reference information database 108b.

[0088] As another example, the CPU 101 can extract high-risk time periods not only when the urine pad is wet based on the output of the wetness detection sensor 20, but also when the urine pad is displaced and / or tilted based on the output of the acceleration sensor 34. When the urine pad is displaced, the fit between the urine pad and diaper and the body decreases, making urine leakage more likely. In addition, if the urine pad is tilted, especially in a sleeping position, urine is more likely to leak from the urine pad and diaper due to sleeping on one's side or turning over in bed. In these examples, the high-risk time period can be, for example, the time period that includes the timing when the urine pad is displaced and / or tilted, and is the time period from when the urine pad is replaced until when it is replaced with the next urine pad.

[0089] In the example shown in Figure 11, for instance, during the time period T1 from the urinary incontinence pad change around 18:00 on the first day of the first target period, through the urinary incontinence pad change around 1:00, to the urinary incontinence pad change around 5:45, four instances of wetting of the urinary incontinence pad, as well as frequent shifting and tilting to the right of the urinary incontinence pad, are detected. Therefore, the CPU 101 can identify this time period T1 as a high-risk time period T1 with a high risk of leakage.

[0090] In S107 of this example, the CPU 101 then extracts absorbent items and / or situations related to the risk of excrement leakage from the first subject information, among the absorbent items and / or situations corresponding to the high-risk time period that were used during the extracted high-risk time period.

[0091] As an example, the CPU 101 can extract records from the first situation record that are related to the risk of excrement leakage during the high-risk period. Specifically, the CPU 101 may, for example, extract records from the first situation record that indicate the situation during or near the high-risk period, determine the relationship between each extracted record and excrement leakage, and extract records with a high relationship. The determination of the relationship between each record and the risk of leakage may be made using a model that calculates an index of the relationship with excrement leakage from the items, content, and / or the time relationship with excrement leakage of each record, generated using sample situation records recorded in the reference information database 108b, or it may be made using a formula or table to derive an index of the relationship with excrement leakage from the items, content, and / or the time relationship with excrement leakage of each record. Examples of time periods considered "near the high-risk period" include the same day as the high-risk period, the time period from the change of the incontinence pad one or several times prior to the high-risk period until the high-risk period, the time period within a predetermined time (e.g., 3 hours, 6 hours, etc.) from the high-risk period, and time periods of a length corresponding to the urination interval of the subject or sample subject.

[0092] In the example shown in Figure 11, the CPU 101 extracts records indicating the situation during the high-risk time period T1 and the surrounding time periods, and determines the relationship of each record to the risk of excrement leakage. As a result, the CPU 101 can extract records that are highly correlated with the risk of excrement leakage, such as: Record R1 of intermittent displacement of the urine pad from around 9pm to 1am; Record R2 of lying on one's side and intermittent displacement of the urine pad from around 1am to 3:30am; Record R3 of intermittent displacement of the urine pad from around 3:30am to 5am; Record R4 of fluid intake around 7pm; Record R5 of toilet assistance; and Record R6 of diaper change.

[0093] In S107 of this example, the CPU 101 then generates a first recommended means for preventing excrement leakage, based on reference information related to absorbent articles and / or situations that have been extracted as being related to the risk of excrement leakage in the subject. For example, the CPU 101 may extract records related to preventing excrement leakage from sample article records and / or sample situation records that have been recorded for absorbent articles and / or situations corresponding to absorbent articles and / or situations related to the risk of excrement leakage in the subject, and generate a first recommended means based on those records.

[0094] In the above example, sample item records recorded for absorbent items and / or absorbent items corresponding to the risk of excrement leakage in the subject include, for example, a sample item record that includes a record of using the same absorbent item that was used during a time when the risk of excrement leakage in the subject was high, and a sample item record that includes a record of using an absorbent item that is associated with the same degree of self-awareness as the absorbent item related to the risk of excrement leakage in the subject. Furthermore, records related to preventing excrement leakage included in these sample item records include a record of changing to an absorbent item with a lower degree of self-awareness. In this case, the CPU 101 may generate a first recommended means, which includes using an absorbent item with a lower degree of self-awareness, based on such sample item records.

[0095] In the example described above, sample situation records that document situations corresponding to absorbent materials and / or circumstances related to the risk of excrement leakage in the subject include, for example, sample situation records that include time periods having patterns similar to the patterns of records related to the risk of excrement leakage during high-risk time periods. The similarity of these record patterns can be calculated by quantifying at least one element selected from items, content, time information, etc., for each record, and using, for example, machine learning techniques for calculating similarity or clustering techniques.

[0096] Furthermore, in the above example, among the sample situation records that record situations corresponding to absorbent items and / or situations related to the risk of excrement leakage in the subject, records related to the prevention of excrement leakage include, for example, records that show a decrease in the risk of excrement leakage in a corresponding time period (hereinafter referred to as the "corresponding time period") on a day later than the day containing a time period with a pattern similar to the record pattern related to the risk of excrement leakage in the subject (hereinafter referred to as the "similar time period"). Specific examples of records showing a decrease in the risk of excrement leakage include, for example, records showing a decrease in the frequency of wetting or leakage of the urine pad based on sensor information, and records showing a decrease in the frequency of tilting or displacement of the urine pad based on sensor information. In addition, the CPU 101 extracts events that have a different pattern from the above-mentioned similar time period, in addition to the sensor information, during the corresponding time period. Such events with different patterns include events where the time (time period) or content has been changed, added events, and the disappearance of corresponding events. Since events with such different patterns are highly likely to be associated with a reduced risk of excrement leakage, the CPU 101 can generate a first recommendation means that recommends the execution of events with such different patterns.

[0097] For example, comparing the time period T2 of the sample status record 700 shown in Figure 12, from the pad change around 6 PM on the second day through the pad change around 1 AM to the pad change around 5 AM, with the high-risk time period T1 of the first status record 600, the patterns of wetness records, water intake records, toilet guidance records, and diaper change records are similar. Therefore, the CPU 101 can extract time period T2 of the sample status record 700 as a "similar time period".

[0098] Next, comparing the similar time period T2 on day 2 of sample status record 700 with the corresponding time period T3 on day 3, it is found that the number of times the urine pad was wet was lower in time period T3 than in time period T2. Therefore, the CPU 101 extracts that, in addition to the sensor information, time period T3 on day 3 (corresponding time period) does not contain the event corresponding to the fluid intake record R7 around 19:00 in time period T2 on day 2, as an event with a different pattern than the similar time period T2 on day 2. As a result, the CPU 101 can generate a first recommendation suggesting that fluid intake around 19:00 be reduced.

[0099] Furthermore, if the CPU 101 extracts multiple events that have a different pattern from those in time period T3 during time period T4, it can generate a first recommendation means that recommends the execution of the event that is highly correlated with the risk of excrement leakage for each of the extracted events. The determination of the correlation between each event and the risk of excrement leakage may be performed, for example, by generating a model that predicts the degree of correlation between the event with the different pattern and the sensor information from multiple other sample status records, and then predicting the degree of correlation using the generated model.

[0100] Next, the CPU 101 transmits (outputs) the generated first recommended means to the user terminal 200 (S108). The CPU 201 of the user terminal 200 receives the first recommended means (S210) and displays the first recommended means on the display unit 206 (S211). The user who has been presented with the first recommended means continues to assist the person in question, for example, while executing the first recommended means.

[0101] The user accesses the excretion care support service after a predetermined period has elapsed since S211. This predetermined period may be a period recommended by the excretion care support service or a period set by the user. After S211, the CPU 201 of the user terminal 200 sends a request to send the item record and status record input form (record input form) (S212). The CPU 101 of the server 100 receives (acquires) the request to send the record input form (S109) and sends the record input form to the user terminal 200 (S110). The CPU 201 of the user terminal 200 receives the record input form (S213) and displays the record input form on the display unit 206 (S214).

[0102] The record input form may be similar to the record input form 500 described above, for example. The user selects, for example, any four days and determines this as the second target period for inputting into the record input form 500, and inputs information into the record input form 500 during the second target period. The CPU 201 of the user terminal 200 receives the input to the record input form 500 (S215) and, based on input operations such as the send button (not shown), sends the input information of the record input form for the second target period to the server 100 (S216). The CPU 101 of the server 100 receives (acquires) the input information of the record input form for the second target period (S111) and stores it in the target person information database 108a of the storage unit 108 (not shown).

[0103] Furthermore, during the second target period, the subjects use the urine collection pad 11 on which the sensor device 50 is placed. The sensor body 30 engages with the terminal portion 24 of the new urine collection pad 11 each time the urine collection pad 11 is replaced. The data logger 32 of the sensor body 30 records data based on the output of the wetness detection sensor 20 and data based on the output of the acceleration sensor 34, associating them with time (S303), and transmits the sensor information, including the data based on the output of the wetness detection sensor 20 and the data based on the output of the acceleration sensor 34, as associated with time, as associated with the identification information of the sensor body 30 (S304).

[0104] The CPU 101 of the server 100 receives (acquires) sensor information (S112) and stores it in the subject information database 108a of the storage unit 108 (not shown).

[0105] Here, the second subject information includes second item information about absorbent articles used by the subject during the second subject period, and second situation information about at least one situation selected from the subject's excretion status, activity status, and sleep status during the second subject period. In this embodiment, the second subject information includes a second item record that records the second item information over time, and a second situation record that records the second situation information over time. That is, in this example of operation, the input information of the record input form 500 for the second subject period and the sensor information for the second subject period are included in the second item record and the second situation record of the second subject information. Specifically, the second item record includes the type of urine pad and the time of its replacement based on the input information of the pad replacement record input field 506 of the record input form 500, and the types of diapers used during the day and at night based on the input information of the outer input field 507. The second status record includes records based on the output of the wetness detection sensor 20 and the output of the acceleration sensor 34 included in the sensor information, the time and amount of water intake based on the input information in the water intake record input field 504 of the record input form 500, the time of toilet guidance and whether or not urination occurred based on the input information in the toilet guidance record input field 505, a record of defecation based on the input information in the defecation record input field 508, and whether or not bathing occurred and the time of bathing based on the input information in the bathing record input field 509.

[0106] Therefore, in this example of operation, the step S111 for acquiring input information for the second item record and the second situation record, and the step S112 for acquiring sensor information function as the "step for acquiring second subject information". In addition, in S111 and S112, the CPU 101 functions as the "second subject information acquisition unit".

[0107] Next, the CPU 101 determines whether the risk of leakage of the subject's excrement predicted from the second subject information is lower than the risk of leakage of the subject's excrement predicted from the first subject information (S113). In this step, the CPU 101 functions as a "determination unit".

[0108] In step S113 of this example, for example, the CPU 101 can calculate the risk level of excrement leakage for the entire or a part of the second target period from the second subject information, and predict the risk of excrement leakage during the second target period based on the calculated level. Indicators of the risk level of excrement leakage include, for example, the frequency and / or amount of wetting detected from sensor information, the degree of displacement or tilting of absorbent articles detected during the time period corresponding to the wetting detected from sensor information, and the degree of mismatch between the absorbency of the urine pad and the frequency and / or amount of wetting. Furthermore, the period for calculating the risk level of excrement leakage may be the entire second target period, a time period corresponding to the high-risk time period mentioned above, or a predetermined period (for example, one day). From the viewpoint of more efficient information processing, it is preferable to use a time period corresponding to the high-risk time period mentioned above.

[0109] The CPU 101 can similarly calculate the risk level of excrement leakage from the first subject information and predict the risk of leakage during the first subject period based on the calculated level. The period for calculating the risk level of excrement leakage during the first subject period may be the period corresponding to the calculation period in the second subject period.

[0110] In step S113 of this example, the CPU 101 then determines whether the risk of excrement leakage predicted from the second subject information is lower than the risk of excrement leakage predicted from the first subject information. For example, the CPU 101 can make this determination by comparing the risk index of excrement leakage calculated from the second subject information with the risk index of excrement leakage calculated from the first subject information.

[0111] Figure 13 illustrates a second status record 800 generated from the input information of the record input form 500 and sensor information during the second target period. In the examples shown in Figures 11 and 13, the CPU 101 determines, for example, that the frequency of wetting in time period T4, which corresponds to the high-risk time period T1 in the second target period, is lower than the frequency of wetting in the high-risk time period T1 of the first target period. As a result, it can be determined that the risk of excrement leakage predicted from the second target person information is lower than the risk of excrement leakage predicted from the first target person information.

[0112] If the risk of leakage predicted from the second subject information is determined to be lower than the risk of leakage predicted from the first subject information (Yes in S113), the CPU 101 generates a task for excretion care for the subject, which includes either using absorbent items associated with a higher degree of independence than the absorbent items used by the subject during the second subject period, or not using absorbent items at all, based on reference information related to the risk of leakage of the subject's excrement predicted from the second subject information (S114). In this step, the CPU 101 functions as a "task generation unit".

[0113] In this step, if the subject is using both incontinence pads and diapers, "using absorbent items corresponding to a higher level of independence than those used by the subject during the second target period" includes changing at least one of the incontinence pads or diapers to one corresponding to a higher level of independence. If the subject is using both incontinence pads and diapers, "not using absorbent items" includes not using at least one of the incontinence pads or diapers. In this example of action, challenges in excretion care for the subject include, for example, challenges including changing to diapers with less absorbency, challenges including changing to incontinence pads with less absorbency, challenges including changing from disposable diapers to cloth diapers, and challenges including changing from tape-type diapers to pull-up diapers.

[0114] For example, the CPU 101 may extract records related to the risk of excrement leakage in the subject during the second target period from the sample status records, and generate tasks based on the sample item records corresponding to the extracted sample status records. Examples of sample status records related to the risk of leakage in the subject during the second target period include sample status records in which a level of excrement leakage risk equivalent to or similar to the level of excrement leakage risk calculated from the second subject information has been calculated, and sample status records having the same or similar pattern as the second status record. The CPU 101 determines whether the degree of independence associated with the absorbent item recorded in the sample item record corresponding to the extracted sample status record is higher than the degree of independence associated with the absorbent item recorded in the second item record, and if it is determined to be higher, it can generate tasks that include using the absorbent item recorded in the sample item record. Alternatively, if the extracted sample item record records that at least one of the urine pads or diapers was not used, the CPU 101 can generate tasks in the sample item record that include discontinuing the use of at least one of the urine pads or diapers.

[0115] Refer to Figure 13 for a specific example. For example, the CPU 101 extracts a sample situation record from the reference information database 108b that detects three instances of wetting similar to the pattern in the second situation record 800 during the time period T4 of the second situation record 800. For example, the CPU 101 extracts information about the absorbent material used by the sample subject during the time period T4 from the sample item record associated with the same sample subject as this sample situation record. For example, the CPU 101 can generate a task based on this absorbent material information.

[0116] Next, the CPU 101 transmits (outputs) the generated task to the user terminal 200 (S115). The CPU 201 of the user terminal 200 receives the task (S217) and displays the task on the display unit 206 (S218). This presents the generated task to the user.

[0117] On the other hand, if it is determined that the risk of leakage predicted from the second subject information is not lower than the risk of leakage predicted from the first subject information (No in S113), the CPU 101 of the server 100 may again send the record input form for the first subject period to the user terminal 200 (S104). This prompts the user to record again, and based on this record, the first recommended means for preventing leakage of excrement can be generated again.

[0118] As described above, the excretion care support system in this example can present a first recommended measure to prevent leakage of excrement based on the first subject information, thereby encouraging the execution of recommended excretion care to prevent leakage of excrement, which greatly affects the subject's quality of life and motivation. Furthermore, if the excretion care support system in this example determines that the risk of leakage of excrement has decreased after the execution of the first recommended measure, i.e., that excretion care is being performed successfully, it can present tasks based on the second subject information, including using absorbent items that allow for greater independence, or not using absorbent items at all. This can gradually promote the subject's independence in excretion and efficiently support excretion care. In addition, by suggesting to the subject the use of absorbent items that are thinner and feel more like underwear, or not using absorbent items at all, the subject can feel lighter and more comfortable, and their motivation for independence in excretion can be improved.

[0119] [Differentiation] In this embodiment, the processing of each step is not limited to the operation examples described above. Modifications of this embodiment will be described below.

[0120] For example, in the first recommended means generation step (S107), it was explained that the CPU 101 extracts from the first subject information the absorbent articles used during the extracted high-risk time period and / or the circumstances corresponding to the high-risk time period that are related to the risk of leakage. However, it is also possible to extract absorbent articles that are related to the risk of leakage.

[0121] In this example, the CPU 101 may determine whether an absorbent item used during a high-risk period is related to the risk of leakage, and if so, it may determine that the absorbent item is related to the risk of leakage. Absorbent items used during a high-risk period can be extracted, for example, from the first item record. Specifically, the CPU 101 may determine, for example, whether the absorption capacity of a urine pad used during a high-risk period is small compared to the number of times and / or the amount of wetting of the urine pad based on the output of the wetness detection sensor 20, and if it is small, it may determine that the urine pad is related to the risk of leakage. In this example, the CPU 101 can determine the amount of absorption of a urine pad by comparing the absorption capacity and / or the number of times urine is absorbed by each urine pad stored in the sample item information of the reference information database 108b with the number of times and / or the amount of wetting of the urine pad based on the output of the wetness detection sensor 20.

[0122] In the example shown in Figure 11, the CPU 101 determines that the absorbent item used during the high-risk period T1 on day 1 is the urine pad (No. 5) worn after 18:00 on day 1 of the first target period, based on the input information in the record input form 500 shown in Figure 10. The CPU 101 then determines, based on the output of the wetness detection sensor 20 and the pad replacement record, that wetness was detected twice during the usage time of the urine pad (No. 5). If the number of times urine was absorbed by urine pad No. 5 stored in the sample item information of the reference information database 108b is 1, the CPU 101 determines that the number of times wetness was detected based on the output of the wetness detection sensor 20 is greater than the number of times urine was absorbed by urine pad No. 5, and determines that there is a high risk of leakage for urine pad No. 5.

[0123] In S107, the method for extracting high-risk time periods is not limited to the examples described above. For example, the CPU 101 may determine a time period as a high-risk period when the amount of absorption (number of times) of the urine pad used is less than the number of times (amount of wetness), based on the timing of changing the urine pad detected based on the first situation record and the timing of wetting detected based on the output of the wetness detection sensor 20.

[0124] Alternatively, in S107, the CPU 101 does not need to extract high-risk time periods. For example, if the CPU 101 determines that the amount of absorption (number of times) of the urine pad used is less than the number of times (amount of wetting) based on the timing of changing the urine pad detected based on the first situation record and the timing of wetting detected based on the output of the wetness detection sensor 20, then the CPU 101 can extract the urine pad as an "absorbent item associated with the risk of excrement leakage." Alternatively, a predictive model that predicts the degree of association with the risk of excrement leakage from the patterns of situation records generated from a large number of sample situation records may be used to extract situations (records) in the first situation record that are associated with the risk of excrement leakage.

[0125] As another variation of S107, if the sample situation record, which records situations corresponding to absorbent items and / or situations extracted as being related to the risk of excretory leakage in the subject, includes a record of countermeasures for the excretory situation, CPU101 may generate a first recommended measure based on the record of countermeasures for improving the excretory situation related to the extracted absorbent items and / or situations. This allows the first recommended measure to present specific countermeasures for the excretory situation, thereby more effectively supporting the prevention of excretory leakage. Examples of countermeasures for the excretory situation include devising ways to apply absorbent items (urine pads and / or diapers) according to the posture of the person being cared for, massage to prevent swelling, daytime exercise, and wearing compression socks.

[0126] Furthermore, as a variation of the task generation step (S114), the CPU 101 may, for example, generate a task regarding excretion care for the subject based on sample item information related to absorbent items recorded in the second item record. The absorbent item extracted from the second item record may be the absorbent item used for the longest period during the second target period, or it may be the absorbent item used during the high-risk period extracted from the second situation record. In this example, the CPU 101 may extract from the sample item information contained in the reference information database 108b an absorbent item identical to the absorbent item extracted from the second item record, and / or an absorbent item associated with a common degree of independence, and generate a task that includes using an absorbent item associated with a higher degree of independence than the absorbent item extracted from the sample item information. Alternatively, if no absorbent item associated with a higher degree of independence than the extracted absorbent item is stored in the sample item information, the CPU 101 may generate a task that includes not using an absorbent item. Alternatively, the CPU 101 may generate a task that involves using an absorbent material to address the risk of leakage predicted from the second situation record.

[0127] <Second Embodiment> In a second embodiment of the present invention, as illustrated in Figure 14, the CPU 101 of the server 100 may, after generating a problem (S114), generate a second recommended means for solving the problem based on reference information related to the problem (S116). In this step, the CPU 101 functions as a "second recommended means generation unit". Note that in the system of this embodiment, the operation of the steps prior to the second recommended means generation step (S114) is the same as in the first embodiment, so a description is omitted.

[0128] As an example of operation in this embodiment, the CPU 101 in S116 may extract records related to preventing leakage of excrement from the sample status records associated with the sample item information used to generate the problem in S114, and generate a second recommendation means based on those records.

[0129] In this example, CPU 101 first extracts sample status records associated with the sample item information used to generate the task in S114. Examples of sample status records associated with the sample item information used to generate the task include sample status records for the same sample subject as the sample item information used to generate the task, sample status records used to generate the task, and sample status records for sample subjects using the same absorbent material as the absorbent material included in the task.

[0130] In this example, the CPU 101 then extracts from the extracted sample situation records records that are related to preventing excrement leakage and have a different pattern from the subject's second situation record. For example, the CPU 101 calculates the similarity between the patterns of each record included in the extracted sample situation records and the records included in the second situation record, and extracts records with low similarity from the sample situation records. Furthermore, for each record with low similarity, the CPU 101 calculates the degree of association with the risk of excrement leakage, and extracts records with a low risk of excrement leakage as records related to preventing excrement leakage.

[0131] For example, among the extracted sample situation records, records that differ in pattern from the second situation record include a high frequency of urination in the toilet, a high frequency of being guided to the toilet, and a different time of day for bathing. In this case, the CPU 101 calculates the degree of association between the frequency of urination in the toilet, the frequency of being guided to the toilet, and the time of day for bathing and the risk of leakage of excrement, as described in the first embodiment. As a result, the CPU 101 determines that the frequency of urination in the toilet and the frequency of being guided to the toilet have a high degree of association with the risk of leakage. Therefore, the CPU 101 can generate a second recommended means that includes increasing the frequency of urination in the toilet and increasing the frequency of being guided to the toilet.

[0132] Next, the CPU 101 transmits (outputs) the generated task and the second recommended means to the user terminal 200 (S117). In this step, the CPU 101 functions as the "second recommended means output unit". The CPU 201 of the user terminal 200 receives the task and the second recommended means (S219) and displays the task and the second recommended means on the display unit 206 (S220).

[0133] According to this embodiment, not only can the user be presented with the problem, but also with a second recommended means for solving the problem, thereby more effectively supporting the resolution of the problem. This makes it possible to more effectively support the gradual independence of the person in excretion.

[0134] <Other Embodiments> Although embodiments of the present invention have been described above, the present invention is not limited to the embodiments described above, and various modifications can be made without departing from the spirit of the present invention.

[0135] In the embodiments described above, examples were shown in which the first and second status information included data based on the output of the acceleration sensor 34. However, the first and second status information may also include data based on the output of a motion sensor other than the acceleration sensor 34 that detects the tilt and / or movement of the absorbent article. Examples of such motion sensors include gyro sensors and motion sensors that include both a gyro sensor and an acceleration sensor. By using such motion sensors, the tilt and displacement of the absorbent article can be detected in the same manner as in the embodiments described above.

[0136] For example, the first and second situational information may include information based on the output of a monitoring device that monitors the subject's activity and sleep status. Examples of monitoring devices include activity trackers, pedometers, motion sensors, blood pressure monitors, and other portable information terminals such as smartphones and smartwatches equipped with application programs capable of monitoring vital data, activity data, and sleep data. By using one or more types of information based on the output of such monitoring devices, it becomes possible to predict the timing of excretion during the day or at night based on detected changes in posture and vital data, and to predict the risk of excretory leakage and the time periods when the risk of leakage is high.

[0137] Furthermore, although the above-described embodiment explains an example in which a portion of the situation record is entered using a record input form displayed on the user terminal 200, the invention is not limited to this. For example, a portion of the situation record may be generated by performing image analysis on image data of the subject captured by the imaging unit 210 of the user terminal 200 or another imaging device.

[0138] Furthermore, the reference information database 108b is not limited to examples that include sample item records and sample status records for each sample subject. For example, the reference information database 108b may include sample item information and sample status information, where the sample status information may be information illustrating at least one situation selected from the excretion status, activity status, and sleep status of a person being cared for who has an independence level corresponding to each absorbent item. Such sample status information may be, for example, data within a range of possible outcomes such as events and evaluation results that represent each situation, obtained by statistically processing the sample status records of multiple sample subjects, or information on how to deal with excretion status. This also makes it possible to generate recommended measures and tasks using the reference information.

[0139] Furthermore, the present invention also applies to methods for supporting excretion care, programs for supporting excretion care, and devices for supporting excretion care, with preferred examples being the same as those described above for the excretion care support system. The present invention is also applicable when an information processing program realizing the functions of the embodiments is supplied to a system or device and executed by a built-in processor. Therefore, the technical scope of the present invention includes programs installed on a computer, media containing such programs, WWW (World Wide Web) servers for downloading such programs, and processors for executing such programs, all necessary for realizing the functions of the present invention on a computer. In particular, at a minimum, a non-transitory computer-readable medium containing a program that causes a computer to execute the processing steps included in the embodiments described above is included within the technical scope of the present invention.
