  Hereinafter, a description will be given of a sensor device (excretion detection device) as an embodiment, a notification system including an information processing system in which the sensor device is used, a notification method, a program, and a recording medium on which the program is recorded. Note that the embodiment described below is merely an example, and there is no intention to exclude various modifications and technical applications that are not explicitly described in the following embodiment. Each configuration of the present embodiment can be implemented with various modifications without departing from the spirit thereof. Further, they can be selected as necessary, or can be appropriately combined.

The sensor device of this embodiment is attached to an absorbent article. Absorbent articles are sanitary goods worn by wearers such as adults and infants who cannot sufficiently manage excretion. This absorbent article absorbs or retains menstrual blood such as urine and feces excreted from the wearer and menstrual blood and vaginal discharge. Examples of the absorbent article include tape-type and pants-type paper diapers (so-called “disposable diapers”), cloth diapers, urine pads, sanitary napkins, panty liners, and the like.
In this embodiment, the composite used by the combination of a pad and a paper diaper is also made into an absorbent article. In other words, as specified in ISO15621, in a use example in which a urine pad (auxiliary pad) as an interior body is held at the wearer or wearing position by a paper diaper as an exterior body, the urine pad and the composite of the paper diaper are also absorbent. Article.
For attaching the sensor device to the absorbent article, the sensor device is not only directly attached to the absorbent article, but also to the underwear or auxiliary tool (holder pants) to which the absorbent article is attached. Indirect mounting is also included.

In the following embodiment, a pants-type paper diaper is illustrated as an absorbent article. About this paper diaper, let the direction which connects the front body arrange | positioned facing a wearer's abdomen, and the back body arrange | positioned facing a back part be a longitudinal direction. Inseam placed between the front body (one side in the longitudinal direction) and the back body (the other side in the longitudinal direction) (center in the longitudinal direction) is placed on the wearer's crotch (placed opposite the crotch) The part is located. In a state where a paper diaper is worn by the wearer (hereinafter abbreviated as “wearing state”), the side facing the wearer's skin (inside in the worn state) is the skin side, and the opposite side (wearing) The outer side in the state is the non-skin side. Furthermore, a direction connecting the skin surface side and the non-skin surface side is a thickness direction, and a direction orthogonal to both the longitudinal direction and the thickness direction is a width direction. Each direction of the attached paper diaper is also used for the sensor device. In addition, viewing from the thickness direction is a plan view.
In the present embodiment, the notation “numerical value X to numerical value Y” means “not less than numeric value X and not more than numeric value Y” unless otherwise specified.

[I. First embodiment]
In the present embodiment, each configuration will be described in the order of a notification system 1 and a notification method using the notification system 1 with reference to the drawings.
In the configuration of the notification system 1, the basic configuration and details of the notification system 1 using the sensor device 10, the sensor device 10 attached to the paper diaper 2, which is the attachment destination of the sensor device 10 used in the notification system 1, and the paper diaper 2. The configuration is described in order.
In the configuration of the notification method, a method of notification using the notification system 1 will be described in time series.

[1. Paper diaper]
First, the basic configuration of the disposable diaper 2 will be described with reference to FIG.
In the paper diaper 2, sheet-like or mat-like members are laminated. Each member to be laminated has air permeability, that is, moisture permeability, in order to suppress stuffiness in the disposable diaper 2. That is, the paper diaper 2 has air permeability.
In the paper diaper 2, three regions of a front body 2A, a crotch 2B, and a back body 2C are arranged along the longitudinal direction, and an absorbent body 2a is built over these three regions.

  The absorber 2a is a mat-like member that absorbs and holds a liquid. For example, a core in which a superabsorbent resin (also referred to as a so-called SAP <Super Absorbent Polymer>) is mixed with pulverized or defibrated pulp (so-called "fluff pulp") is wrapped (wrapped) with a wrap sheet. The core wrap or a laminate in which a waterproof and moisture permeable sheet (back sheet) is laminated on the core wrap is used as the absorbent body 2a.

Moreover, the cover sheet 2b is laminated | stacked on the non-skin surface side of the paper diaper 2 so that the absorber 2a may be coat | covered from the non-skin surface side. The cover sheet 2b is provided to reinforce the paper diaper 2 and improve the touch (for example, touch). The cover sheet 2b is not limited to a single layer structure, and may have a multilayer structure including an inner cover sheet and an outer cover sheet.
The sensor device 10 described below is attached to the non-skin surface side of the cover sheet 2b.

[2. Sensor device]
As shown in FIGS. 1 and 2, the sensor device 10 includes an apparatus main body 11 that detects atmosphere information (hereinafter, abbreviated as “atmosphere information”) in the paper diaper 2, and the apparatus main body 11 is used as a cover sheet. The attachment part 12 attached to 2b is included.
Here, a fastening mechanism in which the cover sheet 2b and the attachment portion 12 are attached to each other is configured.

As the fastening mechanism, a surface fastener that is fixed by mechanical coupling between a hook material (male member) and a loop material (female member) can be used.
The surface fastener is constituted by a combination of a hook material having a large number of protrusions (for example, a hook shape or a mushroom shape) formed on the surface and a loop material having a loop-shaped fiber disposed on the surface. That is, either one of the cover sheet 2b and the attachment portion 12 is provided with a hook material, and the other is provided with a loop material. By using the planar fastener, the hook material and the loop material can be firmly attached while being peelable, and can be used repeatedly.

However, instead of or in addition to the surface fastener, an adhesive, an adhesive tape, or the like may be used for the fastening mechanism.
The apparatus main body 11 is sandwiched between the cover sheet 2 b and the attachment part 12, and the apparatus main body 11 is attached to the crotch 2 </ b> B of the paper diaper 2.

[2-1. Main unit]
The apparatus main body 11 is provided with a sensor 11B that detects atmospheric information and a housing 11A that houses a battery 11C (power supply device) that supplies power to the sensor 11B.
The housing 11A is waterproof in order to protect the built-in sensor unit 11B and the battery 11C from moisture, but is not breathable.

However, a detection port is formed in a part of the housing 11A. The detection part 11a (exposed part) of the sensor part 11B is disposed in the detection port. Therefore, in the apparatus main body 11 in the attached state, the detection unit 11a exposed to the skin surface side detects the atmosphere information. More specifically, a capacitance type detection unit 11a is used, and the detection unit 11a detects the capacitance. Then, the atmosphere information corresponding to the capacitance detected by the processing unit 11b is processed.
Here, the humidity and temperature of the paper diaper 2 located between the detection part 11a and a wearer are detected as atmosphere information. Therefore, in the following description, humidity and temperature detected as atmosphere information are collectively referred to as humidity / temperature.

  In addition, the housing 11A has basic performance required for sanitary equipment. For example, since the apparatus main body 11 is attached to the paper diaper 2 from which urine and feces are excreted, it is preferable that the housing 11A has water resistance, water repellency, and resistance to ammonia. Moreover, it is preferable to give the housing 11A chemical resistance and antibacterial properties against a disinfectant such as hypochlorous acid from the viewpoint of ensuring cleanliness when the apparatus main body 11 is used repeatedly. Furthermore, from the viewpoint of improving the visibility, the housing 11A may be provided with phosphorescence, fluorescence, or light emission.

Moreover, in order to reduce the foreign body feeling of the apparatus main body part 11 with respect to the wearer, the rigidity of the housing 11A may be lowered after the rigidity of the built-in equipment is secured, or the apparatus main body part 11 may be reduced. In consideration of water immersion, the housing 11A (that is, the apparatus main body 11) incorporating the device may have buoyancy.
1 and 2 exemplify the housing 11A having an elliptical shape in plan view, but various shapes and sizes of the built-in sensor unit 11B, various design and design requirements, etc. A housing 11A having a size can be employed. For example, the housing 11A having a smooth surface shape can be employed from the viewpoint of reducing the foreign body sensation of the apparatus main body 11 with respect to the wearer. Further, from the viewpoint of preventing accidental ingestion of the apparatus main body 11 by the wearer, a housing 11A having a dimension in at least one direction larger than a predetermined dimension may be employed.
The apparatus main body 11 described above is attached to the disposable diaper 2 by an attachment part 12 described next.

[2-2. Mounting part]
The attachment part 12 has a shape extending in a larger area than the apparatus main body part 11 after covering at least a part of the apparatus main body part 11 in plan view.
1 and 2 illustrate an attachment portion 12 that is X-shaped in plan view and covers most of the apparatus main body portion 11.

  However, the attachment portion 12 having various shapes and sizes can be adopted according to the shape and size of the device main body 11 to be attached, the design and design requirements, and the like. For example, in order to ensure attachment of the apparatus main body 11 to the paper diaper 2, the attachment part 12 having a size or shape that covers the entire apparatus main body 11 in a plan view can be employed. Moreover, in order to reduce the material of the attachment part 12, the strip | belt-shaped attachment part 12 is also employable.

The attachment portion 12 has at least a part of the ventilation region R _V having a higher air permeability than the paper diaper 2 in order to suppress a decrease in air permeability caused by attaching the apparatus main body portion 11 to the paper diaper 2.
For example, the air permeability of the ventilation region R _V is higher than that of the absorbent body 2a in the crotch part 2B of the disposable diaper 2. Breathable this vent region R _V can be evaluated by airflow resistance. The ventilation resistance is resistance when air flows. Therefore, the smaller the ventilation resistance, the higher the air permeability. Specifically, the ventilation resistance of the ventilation region R _V is preferably 1.00 [kPa · s / m] or less, more preferably 0.80 [kPa · s / m] or less, More preferably, it is 0.50 [kPa · s / m] or less. If attaching portion 12 which airflow resistance with 1.00 [kPa · s / m] or less vent area R _V, typical disposable diaper higher than 2 of breathable, wearer relates breathable enough airflow resistance is small Comfort is ensured. On the other hand, the ventilation resistance of the absorber 2a in the crotch 2B is 1.3 to 1.5 [kPa · s / m].

Here, the entire region of the attachment portion 12 is the ventilation region R _V. For this reason, the ventilation region R _V includes a region where the attachment portion 12 does not overlap the device main body portion 11 in plan view.
As shown in FIG. 3, in the attachment part 12, the ventilation layer 12a and the adhesion layer 12b are laminated | stacked. In the attachment portion 12 in a state where the apparatus main body portion 11 is attached to the paper diaper 2, the adhesion layer 12b is disposed on the skin surface side with respect to the ventilation layer 12a.

Here, the adhesion layer 12b is laminated | stacked with respect to all the ventilation layers 12a. In other words, the shapes of the ventilation layer 12a and the adhesion layer 12b in plan view are the same.
Since the entire area of the attachment portion 12 is the ventilation area R _V , the air permeability of the two layers in which the ventilation layer 12 a and the adhesion layer 12 b are laminated is higher than that of the disposable diaper 2. For example, in addition to the paper diaper 2, the air permeability of the air-permeable layer 12a is set higher than that of the adhesive layer 12b, and the air-permeability of the adhesive layer 12b is set higher than that of the paper diaper 2.

As the air-permeable layer 12a, various known materials such as a nonwoven fabric and a film can be used as long as air permeability is ensured. The air-permeable layer 12a in which various materials are laminated or compounded and partially given different properties may be used. Alternatively, a material having no air permeability or a low material subjected to processing such as perforation and imparting air permeability may be used as the air-permeable layer 12a. In addition, as the adhesion layer 12b, various known materials such as a resin material and an adhesive can be used as long as they are materials constituting one or the other of the fastening mechanisms.
In addition, the mounting portion 12 also has basic performance required for hygiene products including water repellency. For example, a known water repellent material is used for at least one of the ventilation layer 12a and the adhesion layer 12b in order to ensure the water repellency of the attachment portion 12.

Alternatively, from the viewpoint of improving the visibility, the attachment portion 12 may be provided with phosphorescence, fluorescence, or luminescence.
Furthermore, an auxiliary attachment portion that reliably fixes the apparatus main body portion 11 and the attachment portion 12 may be added between the device main body portion 11 and the attachment portion 12. As this auxiliary attachment portion, a member that adheres to the non-skin surface side of the apparatus main body portion 11 and adheres to the skin surface side of the attachment portion 12 can be used.

[3. Information system]
Next, the notification system 1 will be described with reference to FIGS. 4 and 5.
First, the basic configuration of the computer 100, which is a premise of the notification system 1, will be described with reference to FIG. Note that the computer 100 here includes not only stationary and mobile personal computers but also multifunctional portable terminals such as so-called tablets and smartphones.
The computer 100 includes a calculation unit 110 such as a CPU (Central Processing Unit) or MP (Multi Processor), a memory 120 (storage unit) such as a ROM (Read Only Memory) or a RAM (Random Access Memory), and an HDD (Hard). Disk drive), SSD (Solid State Drive), optical drive, flash memory, reader / writer and other external storage devices 121, keyboard and mouse input device 122, display and printer device output device 123, wireless or wired transmission / reception A communication device 124 is provided. Each of these devices 110, 120, 121, 122, 123, 124 is connected to be communicable with each other via a bus 125 such as a control bus or a data bus provided in the computer 100.

The computer 100 is a general-purpose computer that can execute the program 126. This program 126 is installed in the external storage device 121.
The program 126 may be recorded in a recording medium 127 that can be read by an optical drive, a flash memory, a reader / writer, or the like. Alternatively, the program 126 may be recorded in an online storage 128 (storage unit) on a network to which the computer 100 can be connected. In any case, it is sufficient that the program 126 can be executed by downloading the program 126 to the external storage device 121 of the computer 100 or reading the program 126 into the arithmetic unit 110 or the memory 120.

Next, a detailed configuration related to the control of the notification system 1 will be described with reference to FIG.
In the notification system 1, the sensor device 10 described above is provided on the input side of the computer 100, and the notification unit 130 is provided on the output side of the computer 100. The sensor device 10 and the notification unit 130 and the computer 100 are connected so as to be able to transmit information by wireless or wired such as Bluetooth (registered trademark) or wifi. Here, the humidity / temperature is transmitted from the sensor device 10 to the computer 100, and the computer 100 calculates information to be notified by the notification unit 130 based on the transmitted humidity / temperature.

  Note that the notification system 1 can be applied not only to a single wearer but also to a plurality of wearers. That is, the sensor device 10 may be attached to each of the disposable diapers 2 worn by a plurality of wearers, and humidity / temperature may be input from the sensor devices 10 to the computer 100. In this case, ID information for identifying each wearer is output from each sensor device 10 to the computer 100, and the humidity / temperature associated with each ID information is input to the computer 100.

[3-1. Computer]
In the computer 100, the humidity and temperature transmitted from the sensor device 10 are stored (accumulated) in the memory 120 described above. Alternatively, the humidity and temperature transmitted from the sensor device 10 may be accumulated in the online storage 128 such as a data server. In this case, it is assumed that the humidity / temperature stored in the online storage 128 can be accessed from the computer 100.
Subsequently, information regarding the wearer's excretion (hereinafter referred to as “excretion information”) is calculated by the calculation unit 110 based on the humidity and temperature stored in the memory 120 or the online storage 128. Then, the excretion information calculated by the calculation unit 110 is output to the notification unit 130.
Hereinafter, each component will be described in detail in the order of the memory 120, the calculation unit 110, and the notification unit 130.

[3-1-1. memory]
Humidity and temperature are transmitted from the sensor device 10 to the memory 120 at a predetermined cycle. That is, the sensor device 10 outputs humidity / temperature to the computer 100 at a predetermined cycle. The memory 120 stores and accumulates the humidity and temperature transmitted in each cycle.
Here, the predetermined period is set to various periods such as 1 second, 5 seconds, 30 seconds, 1 minute, and 5 minutes. Furthermore, the predetermined period is not limited to a constant period, and may be a variable period.

[3-1-2. Calculation unit]
The calculation unit 110 calculates excretion information based on changes in humidity and temperature stored in the memory 120.
In addition, the calculating part 110 may calculate excretion information based on one fluctuation | variation among humidity and temperature. In this case, the atmosphere information detected by the sensor device 10 may be only humidity or temperature. Thus, when the atmosphere information is a kind, the sensor device 10 can have a simple configuration. On the other hand, when the atmosphere information includes two types of humidity and temperature, the accuracy of the excretion information can be reliably ensured, and more specifically, the type and properties of the excrement can be estimated.

  The calculation unit 110 includes a determination unit 111 that determines a wearer's excretion point (timing of excretion), a timer 112 that measures an elapsed time t from the excretion point, and a type of excrement in order to calculate excretion information. Three functional elements of the classification unit 113 are provided. These functional elements indicate a part of the function of the program 126 to be executed, and are realized by software. However, some or all of the functions may be realized by hardware (electronic circuit), or may be realized by using software and hardware in combination.

<Judgment part>
The determination unit 111 determines the determination time of the wearer based on the amount of change in humidity / temperature. Specifically, when the following condition A1 or A2 set by paying attention to an increase in humidity / temperature fluctuations is satisfied, the wearer's excretion time is determined.
Condition A1: The degree of increase in humidity and temperature is greater than the degree of increase in excretion Condition A2: The humidity and temperature exceed a predetermined increase value The “degree” in the above condition A1 means the amount of fluctuation per unit time . Therefore, it can be said that the condition A1 is that the positive fluctuation amount per unit time of humidity and temperature is larger than the predetermined amount.

This condition A1 is a condition set by paying attention to the degree of increase in humidity and temperature because the humidity and temperature of the disposable diaper 2 rapidly increase during excretion. In this regard, the humidity and temperature rise gradually in the disposable diaper 2 immediately after replacement. However, the degree of increase in humidity and temperature of the disposable diaper 2 during excretion is greater than the degree of increase in humidity and temperature in the disposable diaper 2 immediately after replacement. Therefore, in order to determine the increase in the latter while excluding the increase in the former, the excretion increase is set in advance experimentally or empirically.
Therefore, the “excretion increase degree” of the condition A1 is larger than the increase degree of humidity / temperature in the disposable diaper 2 immediately after replacement as a determination threshold value at the time of excretion, and more than the increase degree of humidity / temperature in the disposable diaper 2 at the time of excretion. Is also set small.

The condition A2 is a condition set by paying attention to the increased values of the humidity and temperature because the humidity and temperature of the disposable diaper 2 are increased during excretion. In this regard, as described in the condition A1, the humidity and temperature values gradually increase in the disposable diaper 2 immediately after the replacement. Then, the humidity and temperature are kept almost constant. At the time of excretion, the humidity / temperature values are further increased from the fixed values. Therefore, in order to determine the latter increase while eliminating the former increase, a predetermined increase value is set in advance experimentally or empirically.
Therefore, the “predetermined increase value” of the condition A2 is a determination value at the time of excretion, which is greater than a certain value of humidity and temperature that is maintained immediately after the disposable diaper 2 is changed, and that has increased at the time of excretion. It is set smaller than the maximum value of temperature.

In addition, the following condition A3 may be included as a condition for determining the excretion time of the wearer.
Condition A3: The temperature of the humidity / temperature is increased and decreased. The condition A3 is set after paying attention to the vertical fluctuation of the temperature because the temperature of the disposable diaper 2 increases after excretion. It is a condition. With respect to this condition A3, in the disposable diaper 2, the temperature does not basically decrease between the time when the diaper 2 is exchanged and the time when it is excreted. On the other hand, in the disposable diaper 2 after excretion, as described above, the temperature rises immediately after excretion, and thereafter the temperature decreases due to heat dissipation of excrement.
Note that the condition A3 is that the temperature rises and falls by more than a predetermined temperature range in order to eliminate small fluctuations in temperature detected by the sensor device 10 other than during excretion and detection errors of the sensor device 10. It is preferable that

Furthermore, the determination unit 111 may determine the replacement time of the disposable diaper 2 (the time when the wearer wears the disposable diaper 2 <wearing point>). Specifically, when the following condition B1 or B2 set by paying attention to a decrease in fluctuations in humidity and temperature is satisfied, the determination unit 111 can determine that it is time to replace the disposable diaper 2. .
Condition B1: The degree of decrease in humidity / temperature is greater than the degree of decrease in replacement Condition B2: Humidity / temperature is below a predetermined decrease value

The condition B1 is a condition set by paying attention to the degree to which the humidity / temperature decreases because the humidity and temperature rapidly decrease in the disposable diaper 2 at the time of replacement, contrary to the condition A1 described above. It can also be said that the condition B1 is that the absolute value of the negative fluctuation amount per unit time of humidity and temperature is larger than a predetermined amount.
In addition, the above condition B2 is a condition set by paying attention to the reduced values of the humidity and temperature because the humidity and temperature are low in the disposable diaper 2 at the time of replacement, contrary to the above condition A2.

The exchange lowering degree and the predetermined lowering value of these conditions B1 and B2 are also set experimentally or empirically in advance as the determination threshold value or the determination value.
However, the determination of the replacement time by the determination unit 111 may be omitted, and the replacement time of the disposable diaper 2 may be manually input to the computer 100 by the wearer or the caregiver.
In addition, the determination unit 111 may be provided with functions such as determination using the above-described conditions B1 and B2 and determination of the presence or absence of excretion from the time of replacement of the disposable diaper 2 obtained by manual input. That is, the determination unit 111 may perform various determinations after setting the replacement time of the paper diaper 2 as a zero point (reference).

<Timer>
The timer 112 measures an elapsed time t from the excretion time determined by the determination unit 111. That is, the timer 112 starts when the condition A1 or A2 is satisfied. Note that the timer 112 is stopped (reset) when the condition B1 or B2 is satisfied or when the replacement time of the disposable diaper 2 is input.

<Classification part>
The classification unit 113 classifies the type of excrement from the wearer based on the degree of decrease in humidity / temperature from the point of excretion determined by the determination unit 111.
The classification unit 113 classifies fluid excrement (fluid excrement) such as urine and menstrual blood and solid excrement (solid excrement) such as feces and excrement. The excrement is classified as a fluid when the following condition C1 is satisfied, and is classified as a solid when the condition C1 is not satisfied.
Condition C1: The degree of decrease in humidity and temperature from the time of excretion is the degree of categorical decrease (first predetermined decrease)
Degree)

The above condition C1 is that fluid excrement has a smaller heat capacity than solid excrement, and fluid excrement diffuses and tends to decrease in temperature, whereas solid excrement diffuses. This is a condition set by paying attention to the fact that it is difficult to lower the temperature.
Therefore, the “classification reduction degree” of condition C1 is smaller than the humidity / temperature reduction degree when fluid excretion is excreted as a determination threshold, and the humidity when solid excretion is excreted.・ It is set larger than the degree of temperature decrease. The “classification reduction degree” is set in advance experimentally or empirically as a degree smaller than the “exchange reduction degree” related to the condition B1 described above.

Further, the classification unit 113 may subdivide the fluid excrement into urine feces (second fluid excrement) and watery feces (first fluid excrement) depending on the success or failure of the following condition C2. Specifically, fluid excrement is subdivided into urine feces when the following condition C2 is satisfied, and fluid excrement is subdivided with watery feces when the following condition C2 is not satisfied.
Condition C2: The degree of decrease in humidity and temperature from the time of excretion is the degree of finer reduction (second predetermined decrease)
The above condition C2 is that, among fluid excreta, urine stool is more likely to diffuse and heat than watery stool (the behavior of humidity and temperature varies depending on the nature). This is a condition set with attention. The “detailed predetermined degree” is set to be larger than the “classified predetermined degree”.

In addition, if the above condition A3 is not included in the determination of the excretion time, the type of excrement from the wearer is classified based on the degree of increase in humidity and temperature from the excretion time determined by the determination unit 111. You can also In this case, various kinds of excrement can be classified or subdivided by replacing various “decrease degrees” used in the above-described excrement classification and subdivision conditions C1 to C3 with “increased degrees”. .
Note that the “excretion increase degree”, “predetermined increase value”, “exchange decrease degree”, “predetermined decrease value”, and “category decrease degree” in the above conditions are set for each of humidity and temperature.

<Calculation of excretion information>
The calculation unit 110 calculates excretion information using the calculation results of the determination unit 111, the timer 112, and the classification unit 113 described above.
The excretion information includes the presence / absence of excretion, the point of excretion, the type of excrement, the wearer's discomfort, and the like. Presence / absence of excretion and excretion time are obtained from the determination result in the determination unit 111, and the type of excrement is obtained from the classification result in the classification unit 113. Furthermore, as shown in Table 1 below, the wearer's discomfort level is the presence / absence of the determination result of the excretion time in the determination unit 111, the elapsed time t measured by the timer 112, and the excrement classified by the classification unit 113. Calculated based on type.

Hereinafter, with respect to the discomfort of the wearer, four calculation methods will be exemplified with reference to Table 1 above.
Here, the degree of discomfort of the wearer is evaluated in three stages in which the degree of discomfort increases in the order of “◯”, “Δ”, and “×”. “◯” is comfortable, “Δ” is somewhat uncomfortable, and “×” indicates a discomfort level that is very unpleasant. Therefore, the unpleasant state is evaluated in two stages, “Δ” and “x”.

The first calculation method is set based on the knowledge that the wearer's comfort is maintained in the state where excrement is not excreted in the disposable diaper 2. Therefore, in the first calculation method, when the determination of the excretion time is not performed by the determination unit 111, the discomfort degree is calculated as “◯”.
On the other hand, the 2nd-4th calculation method is set based on the knowledge that a wearer's comfort is impaired in the state by which excretion was excreted in the paper diaper 2. These second to fourth calculation methods are performed when the determination unit 111 determines the time of excretion.

  Among the second to fourth calculation methods, the second and third calculation methods calculate discomfort due to fluid excrement, and the fourth calculation method calculates discomfort due to solid excrement. Calculate. Therefore, the second and third calculation methods are performed when the type of excrement classified by the classification unit 113 is a fluid, and the second type and the third calculation method are executed when the type of excrement classified by the classification unit 113 is solid. Four calculation methods are implemented.

In the second calculation method, until the predetermined time t _P elapses after the excrement of the fluid is excreted, the temperature decrease due to the heat dissipation of the excrement does not progress, and the comfort of the wearer is improved. It is set based on the knowledge that the decline has not progressed significantly. On the other hand, in the third calculation method, after the excrement of the fluid is excreted and the predetermined time t _P elapses, the temperature decrease due to the heat radiation of the excrement proceeds, and the wearer's comfort is also reduced. It is set based on the knowledge that it has progressed.

Therefore, focusing on the length of the elapsed time t, the elapsed time t is in the second calculation method is a discomfort degree is less than the predetermined time t _P is calculated as "△", the elapsed time t is in the third calculation method is given It is calculated as "×" the discomfort of long time t _P or more.
The “predetermined time t _P ” here is set experimentally or empirically in advance as the time required for the temperature of the disposable diaper 2 to fall below the temperature that impairs the wearer's comfort after excretion. For example, the time until the temperature of the disposable diaper 2 after excretion falls to a temperature maintained before excretion is set to “predetermined time t _P ”.

  The fourth calculation method is set based on the knowledge that when solid excretion is excreted, the wearer's comfort is impaired regardless of the elapsed time t from the excretion point. More specifically, when solid excreta is excreted, it is more difficult to lower the temperature than when excretory fluid-resistant excreta is excreted. However, since the solid excrement continues to intervene between the disposable diaper 2 and the wearer without being absorbed by the absorber 2a, the fourth calculation method is based on the knowledge that the wearer's comfort is reduced. Is set. Therefore, in the fourth calculation method, when the type of excrement classified by the classification unit 113 is solid, the discomfort degree is calculated as “x”.

In addition, the calculating part 110 may calculate excretion information based on the fluctuation amount of humidity and temperature from the point of excretion. For example, the discomfort degree may be set to “x” when the temperature detected by the sensor device 10 has dropped below a predetermined temperature range (predetermined amount) after the excretion point.
The computer 100 executes the arithmetic processing as described above by the program 126 described above.

[3-2-2. Notification Department]
The alerting | reporting part 130 is a device which alert | reports excretion information to a wearer or the caregiver who cares for this wearer.
Examples of the notification unit 130 include a display unit such as a display and a light that are visually displayed (notified), a sound generator such as a speaker and a buzzer that is visually notified, and a vibrator (vibrator) that is tactilely notified. It is done.
Examples of the caregiver notified by the notification unit 130 include caregivers, helpers, and relatives who care for or raise wearers such as adults and infants.

In addition, the notification mode in the notification unit 130 may be controlled by the computer 100 described above. For example, the display content, sound type, vibration pattern, and the like to be notified may be controlled by the computer 100 in accordance with the presence or absence of excretion, the point of excretion, the type of excrement, the degree of discomfort of the wearer, and the like.
When the notification unit 130 is a display, the computer 100 may control aspects such as a list display of various types of excretion information, a display order thereof, and a partial display of various types of excretion information. Furthermore, when the sensor device 10 is attached to each of the paper diapers 2 attached to a plurality of wearers, a list display of the wearer associated with each sensor device 10 and the various excretion information described above, In this list display, the computer 100 may control an aspect such as display in ascending order or descending order (sort display) of each excretion information according to the length of the elapsed time t or the degree of discomfort. Such display mode control processing is executed by the computer 100 by the program 126 described above.

[4. Notification method]
Next, the notification method will be described with reference to the flowchart of FIG. This notification method is a method of notification by the notification system 1 described above.
In this notification method, a detection step (step A10) for detecting the humidity / temperature with the sensor device 10, a calculation step (step A20) for calculating excretion information based on fluctuations in humidity / temperature detected in the detection step, Each step is performed in the order of the notification step (step A30) for notifying the wearer or caregiver of the excretion information calculated in the calculation step.

Next, the calculation process will be described in detail with reference to FIG.
Note that the initial values of the flags F ₁ , F ₂ , F ₂₁ and F ₂₂ and the elapsed time t used in FIG. 7 are set to “0”.
The flag F ₁ is an excretion flag indicating whether or not the excretion time is determined. The excretion flag F ₁ is set to “0” when the excretion time is not determined, and is set to “1” when the excretion time is determined.

The flags F ₂ , F ₂₁ , and F ₂₂ are discomfort level flags regarding the discomfort level for the wearer. These discomfort level flags F ₂ , F ₂₁ , and F ₂₂ are set to “0” when the discomfort level is “◯”, set to “1” when the discomfort level is “△”, and the discomfort level is It is set to “2” when “x”. More specifically, the flag F ₂₁ is a first discomfort degree flag related to fluid excretion. The flag F ₂₂ is a second discomfort degree flag regarding solid excrement. The logical sum of these flags F ₂₁ and F ₂₂ is set as the discomfort level flag F ₂ .

In the calculation process, a determination process (step A21) is first performed. In this determination step, it is determined whether or not the flag F ₁ is “1”. That is, it is determined whether or not the determination unit 111 determines the time of excretion.
If it is determined that there is a determination of the time of excretion in this determination step (F ₁ = 1), the process proceeds to the measurement step (step A22). On the other hand, if it is determined in the determination step that there is no determination of the excretion time (F ₁ = 0), the discomfort level flag F ₂ is set to “0” (step A29).

In the measurement process, measurement of the elapsed time t is started.
Thereafter, it is determined whether or not the condition C1 is satisfied (step A23). That is, a classification process in which the types of excrement are classified by the classification unit 113 is performed.
Different types of excrement in the classification step is classified into fluid, elapsed time t whether the short is determined than the predetermined time t _P (step A24). On the other hand, when the type of excrement is classified as solid in the classification process, the second discomfort level flag F ₂₂ is set to “2” regardless of the elapsed time t (step A27).

If the elapsed time t has not exceeded the predetermined time t _P, set the first unpleasantness flag F ₂₁ to "1" (step A25), the elapsed time t is equal to the predetermined time t _P above, first unpleasantness the flag F ₂₁ is set to "2" (step A26).
Then, the logical sum of the two flags F ₂₁ and F ₂₂ set after the classification process is set to the discomfort level flag F ₂ (step A28).
After the discomfort level flag F ₂ is set, for example, when the condition A3 is satisfied or the replacement time of the paper diaper 2 is input and the paper diaper 2 is replaced, the flags F ₁ , F ₂ , F ₂₁ and F ₂₂ and the elapsed time t is set (reset) to “0”.
And it transfers (returns) to the alerting | reporting process mentioned above.

[5. Time chart]
Next, an example of the notification system 1 and the notification method will be described with reference to the time chart of FIG. In the time chart described here, the paper diaper 2 mounted at time t ₁ is replaced with a new paper diaper 2. Therefore, until time t ₁ , the humidity h / temperature T and flag F related to the disposable diaper 2 before replacement are shown. On the other hand, after time t ₁ , the humidity h / temperature T and flag F regarding the disposable diaper 2 are shown. It is assumed that no excrement is excreted until time t ₁ .
Before the time t ₀ until the disposable diaper 2 is replaced, as shown in FIGS. 8A and 8B, the humidity h and the temperature T of the disposable diaper 2 are in an equilibrium state due to the sweating and body temperature of the wearer. It is held at a substantially constant value.

Then, at the time t _{0 to} t ₁ when the disposable diaper 2 is replaced, the humidity h is dissipated and the temperature T is dissipated, and the humidity h and the temperature T are rapidly decreased. At this time, the humidity h and the temperature T are decreased to a degree greater than the replacement decrease degree, and are below the predetermined decrease values h _PL and T _PL .
At time t ₁ ~t ₂ immediately after replacement of the disposable diaper 2, the perspiration and body temperature of the wearer, humidity h and temperature T gradually increases. In subsequent time points t _{2 to} t ₃ , the humidity h and the temperature T are held at a constant value or a substantially constant value as in the case before the time point t ₀ .

Then, at time t ₃ ~t ₄ when excrement in disposable diaper 2 is excreted, humidity h and the temperature T rises rapidly by moisture and heat excrement. At this time, the humidity h and the temperature T rise to a degree greater than the excretion rise degree, and exceed the predetermined rise values h _PH and T _PH . At this time, as shown in FIG. 8C, the excretion flag F ₁ is set from “0” to “1”. Further, as shown in FIGS. 8D and 8F, the discomfort level flags F ₂ and F ₂₁ are set from “0” to “1”.
After time t ₄ after excrement is excreted in the disposable diaper 2, the temperature T gradually decreases due to heat dissipation of the excrement. As shown by the solid line in FIG. 8 (b), when the waste fluid is excreted, the temperature T tends to decrease at time t ₄ later.

On the other hand, as shown by a two-dot chain line in FIG. 8B, when solid excreta is excreted, the temperature T after the time point t ₄ is unlikely to decrease. For example, at time t ₅ after the time point t _4, when it decreases the degree of the temperature T is smaller than the classification degree of decrease (unsatisfied condition C1) is determined, the type of excrement is classified as a solid. At this time, as shown in FIG. 8E, the second discomfort level flag F ₂₂ is set from “0” to “2”. Therefore, as shown by a two-dot chain line in FIG. 8F, the discomfort degree flag F ₂ is also set to “2”.
At time t ₆ after the time point t _5, the predetermined time t _P from excretion time has elapsed, the temperature T is below the temperature which is maintained prior to excretion. At this time, as indicated by solid lines in FIGS. 8D and 8F, the discomfort level flags F ₂ and F ₂₁ are set from “1” to “2”.

[6. Action and effect]
Since the present embodiment is configured as described above, the following operations and effects can be obtained.
[6-1. Information system]
First, the operation and effect of the notification system 1 will be described.
(1) According to the notification system 1 of the present embodiment, appropriate excretion information is calculated by the calculation unit 110 and notified by the notification unit 130 in accordance with changes in humidity and temperature detected by the sensor device 10. it can.

For example, a wearer who cannot recognize the presence or absence of excretion can be notified that there was excretion.
In addition, it is possible to notify the caregiver of excretion information such as the presence / absence of excretion, the point of excretion, and the degree of discomfort of the wearer. For example, if the notification unit 130 is provided apart from the wearer wearing the paper diaper 2 to which the sensor device 10 is attached, the excretion information can be notified to a caregiver who is not near the wearer.

  Furthermore, if the sensor device 10 is attached to each of the paper diapers 2 worn by a plurality of wearers, the notification system 1 can be used in a care facility or a hospital. In this case, the caregiver's care work can be made efficient while suppressing an increase in the discomfort level of each wearer. Specifically, the disposable diaper 2 of the wearer with excretion or the wearer with high discomfort can be replaced in preference to the wearer without excretion or the wearer with low discomfort.

(2) Since the time of excretion is determined by the determination unit 111 in the calculation unit 110, information on the time of excretion and information based on the time of excretion can be calculated as excretion information.
(3) Moreover, since the elapsed time t from the point of excretion determined by the determination unit 111 is measured by the timer 112 in the calculation unit 110 and the discomfort level of the wearer is calculated based on the elapsed time t, the point of excretion Therefore, the wearer's discomfort degree can be accurately calculated according to the elapsed time t.

(4) In addition, the degree of discomfort of the wearer can be calculated with high accuracy by calculating the excretion information based on the fluctuation amount of humidity and temperature from the point of excretion.
(5) In addition, since the type of excrement is classified by the classification unit 113 in the calculation unit 110, the discomfort level of the wearer can be appropriately calculated according to the type of excrement.

Hereinafter, classification or subdivision of excrement by the classification unit 113 will be described.
The classification unit 113 can classify the types of excrement into fluid excrement and fixed excrement based on the degree of decrease in humidity and temperature. Furthermore, the excrement of the fluid can be subdivided into urine and watery stool by classifying the size into small and small cases among those having a large degree of decrease in humidity and temperature.

Specifically, when the degree of decrease in humidity and temperature is greater than the degree of classification determination, the type can be appropriately classified from fluid excrement according to the nature of the excrement. Further, when the degree of decrease in humidity and temperature is smaller than the degree of classification determination, the type can be appropriately classified from solid excrement according to the properties of the excrement.
In addition, when the degree of decrease in humidity and temperature is greater than the degree of subdivision, the type can be appropriately subdivided from urine according to the properties of fluid excrement. In addition, when the degree of decrease in humidity and temperature is smaller than the degree of subdivision, the type can be appropriately subdivided from watery feces in accordance with the properties of fluid excrement.

The classification unit 113 can perform excretion classification and subdivision using simple parameters such as humidity and temperature without using parameters such as odor and pressure. Thus, by narrowing down the parameters used for the classification algorithm and the subdivision algorithm, the calculation load and processing load of the calculation unit 110 can be suppressed.
(6) In addition, according to the notification method, the program 126 of this embodiment, and the recording medium 127 on which the program 126 is recorded, the same operation and effect as the notification system 1 can be obtained.

[6-2. Sensor device]
Next, operations and effects relating to the sensor device 10 will be described.
(1) According to the sensor device 10 of the present embodiment, the ventilation region R _V of the attachment portion 12 for attaching the device main body 11 to the paper diaper 2 is higher than the air permeability of the paper diaper 2. Therefore, it can suppress that the air permeability of the paper diaper 2 with which the sensor apparatus 10 was attached can suppress, and a wearer's comfort can be ensured.

(2) The ventilation region R _V of the attachment portion 12 includes a region where the attachment portion 12 does not overlap with the device main body portion 11 in a plan view. Air permeability can be ensured.
(3) Since the ventilation layer 12a and the adhesion layer 12b are laminated in the attachment portion 12 where the entire area is the ventilation area R _V , the air permeability in the ventilation layer 12a is secured and the adhesion to the paper diaper 2 in the adhesion layer 12b Can be made compatible.
(4) Further, since the ventilation resistance of the ventilation region R _V is 1.00 [kPa · s / m] or less, the air permeability is reliably ensured.

(5) In addition, since the attachment part 12 has water repellency, for example, the submergence of the detection part 11a of the apparatus main body part 11 is suppressed, which contributes to ensuring the detection accuracy of humidity and temperature.
(6) Furthermore, since the capacitance type detection unit 11a is used, it is possible to detect humidity and temperature without contact with excrement and the wearer. Therefore, the sensor device 10 can be attached to the outside of the paper diaper 2.
Further, the attached sensor device 10 can be removed and used many times. Moreover, since atmosphere information can be detected without touching a wearer's skin, a wearer's skin trouble can be suppressed.

  In addition, since the sensor device 10 can be easily detached from the paper diaper 2 when the paper diaper 2 to which the sensor device 10 is attached is discarded, for example, compared with a conventional paper diaper with a sensor in which a sensor unit is built in an absorber. Thus, the disposal efficiency of the disposable diaper 2 can be improved. From the viewpoint of recycling the used paper diaper 2, it is very useful to be able to remove the sensor device 10. As a result, it contributes to fuel conversion (RFP conversion) of the disposable diaper 2. Alternatively, when the sensor device 10 removed from the paper diaper 2 is discarded without being used again, the metal portion of the sensor device 10 can be separated and recycled.

[II. Example]
Examples relating to the first embodiment will be described below.
In addition, materials, usage amounts, processing contents, processing procedures, and the like shown in the following examples can be changed as appropriate without departing from the gist of the present invention. Therefore, the scope of this case should not be construed as limited by the specific examples shown below.

[Example 1]
In Example 1, an acrylic adhesive (cosmetics) diluted with ethyl acetate to a spunbonded nonwoven fabric (trade name: Ecule 3301A manufactured by Toyobo Co., Ltd.) having a basis weight of 30 g / m ² and made of PET (Polyethylene terephthalate). Product name “HiPAS10” manufactured by Di Pharmaceutical Co., Ltd.) was applied to a thickness of 20 μm, a release paper was pasted, dried at 80 ° C. for 10 minutes, stored at 25 ° C. for 1 week (cured), and cured. Then, a hole forming process was performed to obtain an attachment portion A.
A sensor device is attached to the pad I (extra 800SP made by Oji Napier, the backsheet is a non-woven absorbent body) using this attachment portion A, and a diaper holding the absorbent body I with holder pants is attached to the wearer for sensory evaluation. Carried out. Moreover, each ventilation resistance of the attachment part A and the pad I was measured. Furthermore, the detectability of the sensor device was evaluated.

<Ventilation resistance>
The ventilation resistance (kPa · s / m) was measured with an AUTOMATIC AIR-PERMEABILITY TESTER KES-F8-AP1 (Breathability Tester) manufactured by Kato Tech.
<sensory evaluation>
In sensory evaluation, the diaper with which the sensor apparatus was attached by the attachment part A was worn, and the elasticity was evaluated. “Dampness” corresponds to the degree of discomfort due to stuffiness inside the diaper. Here, sensory evaluation was performed according to the following three criteria.
◎: Level equivalent to the case where no sensor device is attached ○: Slight feeling is slightly higher than when no sensor device is attached, but there is no problem in actual use ×: Extremely high feeling of stuffiness , Level that causes problems in actual use <Detectability>
In the detectability, the detectability of temperature and humidity by the sensor device was evaluated. Here, evaluation of detectability was carried out according to the following two-stage criteria.
○: Temperature / humidity detected without problems ×: Temperature / humidity detected incorrectly

[Example 2]
In Example 2, an attachment portion B was obtained in the same manner as in Example 1 except that an airlaid nonwoven fabric (trade name: Kinocloth manufactured by Oji Kinocross Co., Ltd.) was used instead of the spunbond nonwoven fabric used in Example 1. In Example 2, instead of the pad I, a pad II (Oji Napier Ultra 500 backsheet was a film absorber) was used. And sensory evaluation was implemented similarly to Example 1, and each ventilation resistance of the attaching part B and the pad II was measured.

[Evaluation results]
For Examples 1 and 2, the evaluation results shown in Table 2 below were obtained.

From Table 2 above, it can be seen that in both Examples 1 and 2, the attachment portions A and B have lower ventilation resistance than the absorbent bodies I and II, and the wearer's sensory evaluation is also good.
Furthermore, it can be seen that the detectability of the sensor device is also secured.

[III. Second embodiment]
Next, the sensor device of the second embodiment and the absorbent article and notification system to which the sensor device is attached will be described.
The sensor device of the second embodiment is different from the first embodiment in the location where it is attached. The notification system of the second embodiment is different from the first embodiment in that an information processing system in which a relay unit is interposed between the sensor device and the computer is used. Except for the points described here, the configuration is the same as that of the first embodiment. Explanation of each part is omitted about these composition.
Hereinafter, each component will be described in the order of the sensor device, the absorbent article, and the information processing system.

[1. Sensor device]
As shown in FIG. 10, the absorbent article 4 to which the sensor device 7 of this embodiment is attached is provided with a water-absorbing urine pad 6 (interior body) in addition to a paper diaper 5 (outer body). This paper diaper 5 can also be said to be a wearing tool for fixing the urine pad 6 to the wearer.
In the absorbent article 4, the sensor device 7 is disposed on the skin surface side of the paper diaper 5 and on the non-skin surface side of the urine pad 6. The absorbent article 4 in which the sensor device 7 is disposed between the paper diaper 5 and the urine pad 6 in this way is referred to as “absorbent article 47 with sensor”.

The sensor device 7 includes a detection unit 71 that detects humidity and temperature, and the detection unit 71 that is partially exposed is disposed inside the housing 72. The detection unit 71 described here detects only humidity and temperature.
The housing 72 is formed with a coupling portion 73 to which one end (a part) of the strap 8 is coupled (connected). Although a handle-like coupling portion 73 is illustrated in FIG. 10, various forms that can easily tie the strap 8 can be adopted for the coupling portion 73. For example, a strap hole can be used for the coupling portion 73.
In addition, the sensor apparatus 7 of this embodiment can detect the presence or absence of excretion only by humidity and temperature as described later, and can classify excrement only by humidity and temperature. By using only humidity and temperature in this way, the sensor device 7 can be reduced in size, and the program can be simplified. Therefore, the durability of the sensor device 7 is improved, and the availability (reliability) of the program can be increased. However, the detection target of the sensor device 7 is not limited to humidity and temperature, and may include other targets such as odor and presence / absence of a specific substance.

Furthermore, a detachable hook-and-loop fastener 79 (connecting portion) is attached to the outer surface of the paper diaper 5 on the non-skin surface side for attachment to the absorbent article 4. That is, the sensor device 7 is attached to the absorbent article 4 with the surface fastener 79 on the non-skin surface side. The sensor device 7 attached with the hook-and-loop fastener 79 is only fixed to the non-skin-side paper diaper 5 and is not fixed to the skin-side urine pad 6.
On the skin surface side of the sensor device 7 fixed to the paper diaper 5, a part of the detection unit 71 that is exposed is disposed directly facing the urine pad 6.

Note that the hook-and-loop fastener attached to the sensor device is not limited to a part on the outer surface of the housing, and may be provided on the entire outer surface. Furthermore, the housing of the sensor device may be configured with a hook-and-loop fastener. Further, the attachment / detachment destination of the hook-and-loop fastener is not limited to the paper diaper, but may be a urine pad.
Alternatively, in order to connect the housing of the sensor device 7 and the paper diaper 5, a separate tape (connecting portion) may be used instead of or in addition to the hook-and-loop fastener 79. In this case, from the viewpoint of ensuring the detection accuracy of the detection unit 71, it is preferable to stick the tape to the sensor device 7 or the paper diaper 5 with the detection unit 71 exposed. Therefore, if a tape provided with a hole (opening) is used, the tape is affixed while overlapping the position of the detection unit 71 and the hole, thereby ensuring the detection accuracy of the detection unit 71 with respect to the paper diaper 5. The sensor device 7 can be securely attached.

In addition, the sensor device 7 is provided with a power button 74 arranged facing the skin surface in the mounting posture, and indicators 75 (two on the left and right of the power button 74 in this case) indicating the operating state of the sensor device 7. .
By pressing the power button 74, the sensor device 7 is turned on, humidity and temperature are detected at a predetermined cycle, and information on the detected humidity and temperature is transmitted at a predetermined cycle toward the relay device 90 described later. Sent. The indicator 75 changes the display color and the blinking pattern according to the operating state of the sensor device 7.

[2. Absorbent article]
Next, a configuration for attaching the sensor device 7 to the absorbent article 4 will be described.
The paper diaper 5 is provided with a guide unit 51 that guides the sensor device 7 to a predetermined position. Here, the “predetermined position” is an appropriate position of the sensor device 7 with respect to the paper diaper 5 that is set based on the viewpoint of ensuring the detection accuracy of the sensor device 7 and the sense of discomfort to the wearer of the paper diaper 5. is there. For example, in the crotch part 5B of the paper diaper 5, a “predetermined position” is set slightly toward the front body 5A.

The guide unit 51 is configured as a picture displayed on the non-skin surface side of the paper diaper 5. For example, various patterns such as a contour line, an arrow, and a cross mark (so-called “dragonfly”) of the sensor device 7 can be used for the guide unit 51.
However, the guide unit 50 is not limited to a pattern, and a guide structure such as a concave portion or a broken line having a size corresponding to the sensor device 7 may be adopted for the guide unit 51.

Further, the paper diaper 5 is provided with a second coupling portion 52 to which the other end (other portion) of the strap 8 is coupled. Here, the second coupling portion 52 is provided on the front body 5 </ b> A of the paper diaper 5.
As with the coupling portion 73 of the sensor device 7, various forms that can easily couple the strap 8 can be adopted for the second coupling portion 52.

Moreover, the 2nd coupling | bond part 52 is arrange | positioned in the location which can be looked at by a mounting state. That is, the 2nd coupling | bond part 52 is provided in the outer surface of the paper diaper 5, and is provided in the location which is easy to visually recognize from the outside. Therefore, one end of the strap 8 is coupled to the coupling portion 73 inside the absorbent article 4, and the other end is coupled to the second coupling portion 52 outside the absorbent article 4. In other words, the strap 8 extending to the outside of the disposable diaper 1 is connected to the housing 72.
The dimensions of the strap 8 coupled to the coupling portions 73 and 52 are the shortest path connecting the coupling portion 73 and the second coupling portion 52 of the sensor device 7 along the shape of the disposable diaper 5 and the urine pad 6. The length is set according to the dimensions.

[3. Information processing system]
Next, an information processing system used by the notification system will be described.
As shown in FIG. 11, in the information processing system 30, a plurality of relay machines 90 (relay units) are connected to the cloud computer 100 ′ (computer), and a plurality of sensor devices 7 are connected to each of the relay machines 90. ing.
The notification system 3 is constructed using the information processing system 30 having such a tree-structured network topology. In addition to the information processing system 30, the notification system 3 includes a notification device 130 ′ (notification unit) connected to the cloud computer 100 ′.
In addition, in FIG. 11, each sensor apparatus 7 is distinguished and shown with code | symbol 7A-7G. Further, when distinguishing each relay device 90, description will be made using reference numerals 91 and 92.

Hereinafter, the nodes (sensor device 7, relay 90, cloud computer 100 ′) of the information processing system 30 will be described. Here, an example is given in which the information processing system 30 is applied to a facility where a plurality of care recipients such as a care facility and a hospital stay.
In the information processing system 30, the absorbent article 47 with a sensor is attached to each of a plurality of care recipients (wearers).

In addition, a repeater 90 is installed for each space (a different point) where a group of care recipients can stay. For example, a first repeater 91 is installed in a bedroom L ₁ (first point) of a quadruple room, and a second repeater 92 is installed in a dining room L ₂ (second point) adjacent to the bedroom L ₁ .
11 includes four sensors with the absorbent article 47A, 47B, 47C, care recipient for mounting the respective 47D are staying in the bedroom L _1, three sensors with the absorbent article 47E, 47F, the 47G care recipient to attach the respectively illustrate the situation staying in cafeteria L _2.

For example, if the first sensor-equipped absorbent article 47A is mounted to the first care recipient bedroom L _1, the first sensor unit 7A attached to the absorbent article. 4A, the humidity and temperature of the absorbent article 4A And the detection information (atmosphere information) is transmitted to the first repeater 91 wirelessly.
Similarly, and fifth sensor with the absorbent article 47E is mounted to a fifth care recipient canteen L _2, the fifth sensor device 7E attached to the absorbent article. 4E, humidity, the absorbent article 4E The temperature is detected, and this detection information is transmitted to the second repeater 92 wirelessly (for example, Bluetooth (registered trademark)).

The repeaters 91 and 92 have a function of displaying the detection information transmitted from the sensor device 7 and display the change over time of the detection information corresponding to each care recipient as it is.
The repeaters 91 and 92 transmit information transmitted from the plurality of sensor devices 7 to the cloud computer 100 ′ wirelessly (for example, 3G line) or wired. In this way, the detection information of the sensor device 7 is transmitted to the cloud computer 100 ′ via (relays) the relay machines 91 and 92.

Further, the identification information of the relay devices 91 and 92 (unique relay devices) passed through is associated with the detection information transmitted from the relay devices 91 and 92 to the cloud computer 100 ′. For example, the detection information of the third sensor device 7C is transmitted to the cloud computer 100 ′ together with the identification information of the first repeater 91.
The cloud computer 100 ′ includes a calculation unit 110 ′, a determination unit 111 ′, a timer 112 ′, a classification unit 113 ′, a memory 120 ′, and the like having at least the functions described in the first embodiment.

  This computing unit 110 ′ estimates the position of the care recipient who wears the absorbent article 4 to which the corresponding sensor device 7 is attached, based on the identification information associated with the transmitted detection information. Specifically, it is estimated that a care recipient is located at or around the point where the relay device 90 is installed via the detection information of the sensor device 7.

On the contrary, if the detection information of the predetermined sensor device 7 is not transmitted to the cloud computer 100 ′, a care recipient corresponding to the predetermined sensor device 7 is located at or around the place where the relays 91 and 92 are installed. Estimated not.
More specifically, the sensor device 7 of the information transmission source is stored in the memory 120 ′ of the cloud computer 100 ′, and when the detection information of the sensor device 7 stored in the memory 120 ′ cannot be obtained, the sensor device 7 is supported. The computing unit 110 ′ estimates that the care recipient who is in need does not exist within a range in which the detection information can be transmitted to the repeaters 91 and 92.

  In addition, the cloud computer 100 'is connected to a notification device 130' such as a stationary or mobile personal computer 130A '(notification unit) or a multi-function mobile terminal 130B' (notification unit) such as a so-called tablet or smartphone. The In addition to the estimated position information of the care recipient described above, excretion information calculated based on the detection information of the sensor device 7 is transmitted from the cloud computer 100 ′ to the notification device 130 ′. Then, the excretion information is notified to a caregiver or relative who has the notification device 130 '.

[4. Action and effect]
Since the present embodiment is configured as described above, the following operations and effects can be obtained.
[4-1. Sensor device]
First, the operation and effects relating to the sensor device 7 will be described.
(1) If the sensor device is attached to the outer surface (surface on the non-skin surface side) of the paper diaper, the sensor device is easily dropped from the paper diaper, but the uncomfortable feeling of the sensor device with respect to the wearer can be suppressed. On the other hand, when the sensor device is attached to the inner surface (the surface on the skin side) of the urine pad, the sensor device tends to give a strange feeling to the wearer, but the sensor device can be prevented from falling off.
On the other hand, since the sensor apparatus 7 of this embodiment is arrange | positioned on the skin surface side with respect to the paper diaper 5, it does not expose outside and the drop-off from the paper diaper 5 is suppressed. Moreover, since the sensor apparatus 7 is arrange | positioned at the non-skin-surface side of the urine pad 6, it does not contact a wearer directly and can suppress the discomfort with respect to a wearer. Thus, according to the sensor device 7 arranged between the paper diaper 5 and the urine pad 6, it is possible to achieve both secure attachment of the sensor device 7 to the absorbent article 4 and suppression of a sense of discomfort to the wearer.

  (2) If the strap 8 is tied to the coupling portion 73 formed on the housing 72 of the sensor device 7, the sensor device 7 can be easily detached from the absorbent article 4 by pulling the strap 8. Thus, the work load concerning the removal of the sensor device 7 can be reduced. Moreover, since the sensor apparatus 7 can be removed without direct contact, even if the sensor apparatus 7 is contaminated, the hygiene of the removal operator can be ensured.

(3) Furthermore, since the sensor device 7 is attached to and detached from the paper diaper 5 with the hook-and-loop fastener 79, the sensor device 7 can be easily attached and detached, and the load on the attachment and detachment work of the sensor device 7 can be suppressed. .
(4) Since the sensor device 7 is attached to the paper diaper 5 with the detection unit 71 exposed from the housing 72 to the skin surface side, the detection accuracy of the detection unit 71 can be ensured. Specifically, the detection unit 71 is disposed directly opposite to the urine pad 6 to accurately detect changes in humidity and temperature caused by excretion excreted in the urine pad 6. Can do.

(5) Since the guide unit 51 for guiding the sensor device 7 to a predetermined position is provided in the paper diaper 5, the sensor device 7 can be easily attached to the paper diaper 5 at an appropriate position.
(6) Specifically, the sensor device 7 can be disposed at an appropriate position simply by aligning the sensor device 7 with the picture displayed as the guide unit 51.
When a guide structure such as a concave portion or a broken line is adopted for the guide portion 51, the sensor device 7 can be easily placed in an appropriate position with respect to the paper diaper 5 simply by arranging the sensor device 7 according to the guide structure. Can be attached to.

(7) If the strap 8 tied to the coupling portion 73 of the sensor device 7 is also tied to the second coupling portion 52 of the paper diaper 5, the sensor device 7 can be reliably prevented from falling off.
(8) Since the second coupling portion 52 is arranged at a position where appearance is possible, when the strap 8 tied to the coupling portion 73 of the sensor device 7 is tied to the second coupling portion 52, The strap 8 can also be appearance. Therefore, the presence or absence of the sensor device 7 can be grasped from the appearance.

  (9) Further, the size of the strap 8 coupled to the coupling portions 73 and 52 is determined so that the coupling portion 73 and the second coupling portion 52 of the sensor device 7 are aligned with the shapes of the worn paper diaper 5 and the urine pad 6. Since the length is set according to the dimension of the shortest path to be connected, the attachment of the sensor device 7 to an inappropriate position can be restricted. Also from this point, the sensor device 7 can be attached to an appropriate position.

[4-2. Information processing system]
Next, operations and effects relating to the information processing system 30 will be described.
(1) Since the information processing system 30 of the present embodiment employs a tree-type network topology having a wireless communication repeater 90, the battery performance and information transmission distance required for the sensor device 7 are suppressed. Can do. Therefore, the sensor device 7 can be reduced in size and cost. Thereby, providing useful information for the wearer and the caregiver based on the information detected by the sensor device 7 while suppressing a sense of incongruity for the wearer wearing the absorbent article 4 to which the sensor device 7 is attached. Can do.

By the way, the tree-type network topology is used not only for the information processing system 30 of this embodiment but also for communication of portable terminals such as GPS (Global Positioning System) terminals and PHS (Personal Handy-phone System) terminals. For such a portable terminal, the sensor device 7 of the present embodiment is attached to a paper diaper 5 that is worn by the wearer.
Therefore, while the mobile terminal is a device that is consciously carried by the wearer, the sensor device 7 is a device that is arranged in a state in which it is difficult for the wearer to be conscious. More specifically, the disposable diaper 5 to which the sensor device 7 is attached is for adults or for nursing care that is worn by a wearer who is physically or mentally difficult to hold the portable terminal.

  If the wearer wearing the paper diaper 5 hangs and holds the portable terminal from the neck with a string, the wearer's action may be hindered, and the string on the neck may cause inflammation. is there. Alternatively, the wearer may leave or discard the mobile terminal. On the other hand, since the sensor device 7 is built in the disposable diaper 5, there is no problem with the above-described portable terminal.

(2) Further, in the calculation unit 110 ′ of the information processing system 30, the position of the wearer is estimated based on the identification information of the relay 90 through which the detection information of the sensor device 7 has passed. Therefore, the position of the wearer can be estimated without attaching a position detection device such as a GPS device or a beacon device separately.
(3) Specifically, it is possible to estimate the position of the wearer of the absorbent article 47 with the sensor at the grounded point of the relay device 90 through which the detection information of the sensor device 7 has passed or in the vicinity thereof. When the information processing system 30 is applied indoors such as a care facility or a hospital, it is possible to estimate the position of the wearer that cannot be measured by the GPS device.

  (4) On the contrary, if the detection information of the predetermined sensor device 7 is not transmitted to the cloud computer 100 ′ in the information processing system 30, the range in which the wearer to which the sensor device 7 is attached can communicate with the repeater 90 It can also be estimated that it is located outside. Thereby, a wearer's wrinkle or disappearance can also be grasped in an initial stage.

[IV. Modified example]
Finally, other modifications of the present embodiment will be described.
For example, a replaceable urine pad may be attached to the inside of the paper diaper 2 to which the sensor device 10 is attached. In such a paper diaper 2, in order to ensure the detection accuracy of the sensor device 10, the apparatus main body 11 is attached to the skin surface side of the paper diaper 2 disposed outside the urine pad by the attachment part 12. In this case, there is a possibility that the detection unit 11 a is disposed on the skin surface side of the apparatus main body unit 11 and the detection unit 11 a is covered with the attachment unit 12.
In the sensor device 10 used in this manner, the area covering the detection portion 11a from the skin surface side of the mounting portion 12 by including a vent region R _V, it is possible to ensure detection accuracy of the detection portion 11a .

Further, as shown in FIG. 9, an attachment portion 11 ′ in which an adhesion layer 12 b ′ is laminated on a part of the ventilation layer 12 a ′ may be used. FIG. 9 illustrates an example in which a plurality of adhesion layers 12b ′ extending along the longitudinal direction are provided side by side in the width direction, and each of the adhesion layers 12b ′ is stacked on the ventilation layer 12a ′. However, the adhesion layer 12b ′ may be provided in various patterns such as a lattice shape or a dot shape.
According to the attachment part 11 ′ in which the adhesion layer 12b ′ is laminated on a part of the ventilation layer 12a ′, the ventilation of the other part of the ventilation layer 12a ′ can be improved and the wearer's comfort is surely lowered. Can be suppressed. Further, the material of the adhesion layer 12b ′ can be reduced, which contributes to reduction in material cost and weight reduction.

Further, a vent 13 'may be provided in the attachment portion 11'. FIG. 9 illustrates a vent hole 13 ′ drilled in the other part of the vent layer 12 a ′ (region where the adhesion layer 12 b ′ is not laminated). However, a ventilation hole penetrating the two layers of the ventilation layer 12a 'and the adhesion layer 12b' may be formed.
According to the vent hole 13 ′, the air permeability of the attachment portion 11 ′ can be reliably improved, and the deterioration of the wearer's comfort can be further suppressed, which contributes to weight reduction.

In addition, the sensor devices 7 and 10 may have a plurality of sensor devices 7 and 10 attached to one paper diaper 2. In this case, it is preferable that each of the sensor devices 7 and 10 is attached to a plurality of locations overlapping with the absorber 2a in plan view.
Thus, the area | region where the excretion was excreted in the paper diaper 2 can also be detected by attaching the several sensor apparatus 7 and 10. FIG. Further, the calculation units 110 and 110 ′ may classify the types of excrement according to the excretion excretion region. For example, when excrement is excreted in the back body 2C, the excrement can be classified into a solid, and when excrement is excreted in the front body 2A, the excrement can be classified into a fluid. In addition, by estimating the area of the wet portion from the excretion region, it is possible to determine the amount of excreted excreted matter, the amount of excreted absorbed matter, the presence or absence of leakage, and the like. Thereby, it is possible to efficiently select the most suitable diaper and pad for the wearer.

  Note that the atmosphere information that is the detection target of the sensor devices 7 and 10 is not limited to humidity and temperature as described above, but may be various information detected by changes in electrical characteristics such as odor and color of excrement. Good. The sensor device 10 may detect only at least one of these detection targets as atmosphere information. In these cases, various information detected by the sensor devices 7 and 10 and excretion information calculated based on this information can be notified to the wearer and the caregiver.

Furthermore, the calculation units 110 and 110 ′ may calculate the excretion timing as the excretion information. Specifically, the calculation units 110 and 110 ′ accumulate information on the time of excretion for each of one wearer or a plurality of wearers, and for each wearer based on the accumulated information on the time of excretion. The excretion timing may be predicted. For example, information on the number of times of excretion is accumulated for each time zone divided every thirty minutes or every hour, and the time zone with a large number of times is calculated as the excretion timing (predicted excretion time).
In addition, the elapsed time from the point of excretion, the frequency of excretion, and the excretion timing predicted for each wearer may be displayed on the notification unit 130. In this way, by informing the caregiver of the predicted excretion time, the excretion frequency and the elapsed time that can be used as the prediction material, the timing and order of guidance to the toilet for each wearer and replacement of the disposable diaper 2 can be optimized. You can also.

On the other hand, the comfort level may be omitted from the excretion information, and the type of excrement classified by the classification units 113 and 113 ′ may be included in the excretion information.
Furthermore, as a method of classifying the types of excrement, various algorithms using changes in the atmosphere information can be adopted, and algorithms focusing only on the magnitude (value) of the atmosphere information can also be adopted. Hereinafter, the former categorization method is given as a first modification, and the latter categorization method is given as a second modification.

――First modification――
In the first modification, on the premise that the temperature detected by the sensor devices 7 and 10 rises over a predetermined range within a predetermined period, the humidity detected by the sensor devices 7 and 10 (hereinafter “ The type of excrement is classified according to the degree of increase in the detected humidity.
An example of the “predetermined period” here is a period set in advance as the length of time required for the wearer to excrete. Moreover, as an example of the “predetermined range”, a range set in advance as the lower limit of the amount by which the temperature rises at the time of excretion of the wearer can be mentioned regardless of the type of excrement. Furthermore, from the viewpoint of shortening the period from the start of excretion until the type of excrement is classified, the “predetermined period” is preferably as short as possible, and the “predetermined range” is as small as possible. Further, from the viewpoint of accurately classifying the types of excrement, the longer “predetermined period” is preferable, and the larger “predetermined range” is preferable.

For example, the type of excrement is classified according to each of the patterns 1A to 3A within a predetermined period. In the following “first range” and “second range”, the “second range” is larger than the “first range”.
・ Pattern 1A: The detected humidity rises within the first range ・ Pattern 2A: The detected humidity rises within the second range beyond the first range ・ Pattern 3A: The detected humidity rises beyond the second range

  In the case of the above-described pattern 1A, the type of excrement is classified as solid excrement (solid excrement). In the case of the above-described pattern 2A, the type of excrement is classified as watery feces (first fluid excrement). In the case of the pattern 3A described above, the type of excrement is classified as urine (second fluid excrement). In these patterns 1A to 3A, the type of excrement is classified by paying attention to the magnitude of the humidity increase width according to the amount of water contained in various excrement.

-Second modification-
In the second modified example, on the assumption that the temperature detected by the sensor devices 7 and 10 is equal to or higher than a predetermined value, the type of excrement is classified according to the level of humidity detected by the sensor devices 7 and 10.
An example of the “predetermined value” here is a value set in advance as the lower limit of the temperature detected when the wearer excretes. Furthermore, from the viewpoint of shortening the period from the start of excretion until the type of excrement is classified, the “predetermined value” is preferably as low as possible, and from the viewpoint of accurately classifying the presence or absence of excretion, the “predetermined value” is as hard as possible. .

For example, the type of excrement is classified according to each of the following patterns 1B to 3B.
-Pattern 1B: The detected humidity is below the first threshold-Pattern 2B: The detected humidity is above the first threshold and below the second threshold-Pattern 3B: Above the second threshold In the case of the above-described pattern 1B, The type of excrement is classified as solid excrement (solid excrement). In the case of the pattern 2B described above, the type of excrement is classified as watery stool (first fluid excrement). In the case of the pattern 3B described above, the type of excrement is classified as urine (second fluid excrement). In these patterns 1B to 3B, the type of excrement is classified by paying attention to the humidity level (humidity value itself) according to the amount of water contained in various excrement.

In addition, regarding the classification of excrement, if the temperature detected by the sensor device continues beyond the predetermined period regardless of the detected humidity, the type of excrement is classified as solid excrement. May be. Further, when the degree of increase in detected humidity is small and the degree of decrease in detected humidity is large thereafter, the type of excrement may be classified as urine and the amount of excreted urine may be determined to be small.
Note that the types of excrement classified by the classification units 113 and 113 ′ and the values and ranges used for the classification can be appropriately rewritten. For example, the types of excrement classified by the classification units 113 and 113 ′ can be manually corrected. Furthermore, based on the correction data for the type of excrement, the values and ranges used for classification may be optimized, or the type of excrement classified by such autonomous calculation may be corrected automatically. Good.

  Alternatively, in order to manage nursing care records, excretion records, childcare records, childcare records, etc., in the notification system 1, various data such as detected atmosphere information, excretion time, and discomfort are displayed on the display other than the notification units 130 and 130 ′. Or output to a printer or the like. In this case, for example, the work of creating an excretion record table can be automated, and the work load related to care, childcare, and childcare can be reduced.

The air permeability in at least a part of the ventilation region R _V of the attachment portions 12 and 12 ′ may be equivalent to the air permeability of the disposable diaper 2. That is, it is only necessary that the ventilation region R _V of the attachment portions 12 and 12 ′ has air permeability that is greater than that of the disposable diaper 2. Also in this case, it is possible to suppress a decrease in the air permeability of the paper diaper 2 due to the attachment of the sensor device 10, and it is possible to ensure the wearer's comfort.
