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 holds manure such as urine and feces excreted from the wearer, menstrual blood and urine (hereinafter collectively referred to as “excrement”). Examples of the absorbent article include tape-type and pants-type paper diapers (so-called “disposable diapers”) or 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. That is, as specified in ISO15621, in a use example in which a urine pad (auxiliary pad) as an interior body is held at a 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.

Further, in a state where the absorbent article is attached to the wearer (hereinafter abbreviated as “wearing state”), the side facing the wearer's skin (inside in the wearing state) is the skin side, and the opposite side of the skin side (Outside in the wearing state) is the non-skin surface 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 absorbent article to be attached 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, a paper diaper, which is a mounting destination of a sensor device used in an information processing system, and a sensor device attached to the paper diaper will be described with reference to the drawings. Next, each configuration will be described in the order of an information processing system, a notification system including the information processing system, and a notification method using the notification system. In the configuration of the notification method, a method of notification using the notification system will be described in time series.

[1. Paper diaper]
A basic configuration of the disposable diaper 2 will be described with reference to FIGS.
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 L, 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 be a multilayer structure including an inner cover sheet and an outer cover sheet. As shown in FIG. 1, the cover sheet 2b in the front body 2A and the cover sheet 2b in the back body 2C are attached to each other in the width direction W edge portion 2d (so-called “side seal”). In this way, the cover sheets 2d of the front body 2A and the back body 2C are continuously provided, and the pant-type paper diaper 2 shown in FIG. 2 is formed.

The paper diaper 2 shown in FIGS. 1 and 2 is a guide for attaching the sensor device 10 described below to a predetermined position on the non-skin surface side of the cover sheet 2b, that is, on the outer surface (most non-skin surface side) of the paper diaper 2. Part 20 is provided. By providing the guide unit 20 on the paper diaper 2, the positioning and attachment of the sensor device 10 is facilitated. Moreover, since the guide part 20 is provided in the surface by the side of the non-skin surface of the cover sheet 2b, the sensor apparatus 10 can be easily attached even if the paper diaper 2 is attached.
The “predetermined position” at which the guide unit 20 is provided is set based on the viewpoint of ensuring the detection accuracy of the sensor apparatus 10 or the viewpoint of suppressing a sense of discomfort for the wearer of the paper diaper 2, and the like. Appropriate position. Here, a “predetermined position” is set in the crotch part 2 </ b> B of the paper diaper 2. Specifically, the guide unit 20 is provided in the central region of the crotch 2B, that is, the region including the center of the paper diaper 2 (the center in the longitudinal direction L and the width direction W of the paper diaper 2).
When the sensor device 10 is attached to the front body 2A of the disposable diaper 2, the sensor device 10 is separated from the anus facing portion 21, so that it may be difficult to detect solid excrement such as feces. On the other hand, if the detection accuracy is improved, the information transmission unit (detection unit) in the sensor device 10 may be increased in size. That is, it is difficult to achieve both improvement in detection accuracy and downsizing of the apparatus.
Further, when the sensor device 10 is attached to the back body 2C, when the wearer is sleeping or sitting, a blood circulation disorder occurs due to pressure or friction of the wearer's skin by the sensor device 10, and pressure ulcer ( So-called bedsores may develop.
Therefore, a guide portion 20 for guiding the mounting position of the sensor device 10 is provided in the crotch portion 2B from the viewpoint of achieving both improvement in detection accuracy and downsizing of the device and preventing bed slip. When the sensor device 10 is attached to the guide unit 20, even when the wearer is sleeping or sitting, the pressure and friction of the wearer's skin by the sensor device 10 are suppressed. Can be prevented. The guide portion 20 is a region sandwiched between the thighs, and in this region, even when the wearer is sleeping or sitting, stress generated on the wearer's skin from the sensor device 10 is small. This is probably because of this. Moreover, since the guide part 20 is located in the approximate middle between the urethral opening facing part 22 and the anus facing part 21, the sensor device 10 can detect solid excretion and fluid excretion with a good balance.
Therefore, according to the paper diaper 2 in which the sensor device 10 is attached to the guide unit 20, the excrement can be detected with high accuracy. Further, the wearer's discomfort and the floor slip caused by the sensor device 10 can be suppressed.

Further, a second guide for attaching to the paper diaper 2 a sensor device 10 ′ (also referred to as “second excretion detection device”) different from the sensor device 10 (also referred to as “first excretion detection device”). A portion 20 ′ may be provided. The second guide portion 20 ′ is provided in an end region on one side of the longitudinal direction L (in the front body 2 </ b> A direction) in the crotch 2 </ b> B, specifically, a region including the urethral opening facing portion 22. In addition, the second guide portion 20 ′ is provided on the non-skin surface side of the cover sheet 2b, similarly to the guide portion 20 (also referred to as “first guide portion 20”).
By providing the second guide portion 20 ′ in the paper diaper 2, the positioning and attachment of the sensor device 10 ′ is facilitated. When the sensor devices 10, 10 ′ are attached to the paper diaper 2, the sensor device 10 near the anus facing portion 21 detects humidity and temperature related to solid excrement such as feces, and the sensor device 10 near the urethral opening facing portion 22. Detect humidity and temperature related to fluid excrement such as urine. In this way, by separating the properties of excrement detected by the sensor devices 10 and 10 ′ according to the attachment position, the configuration of each sensor device can be simplified, and the detection accuracy of each sensor device can be improved. In addition, the size of the sensor device itself can be reduced, and the discomfort for the wearer can be further reduced. In addition, in FIG. 5, the wearer 80 shows the cross-sectional schematic diagram of the state which mounted | wore with the paper diaper 2 to which sensor apparatus 10,10 'was attached. Thus, the paper diaper 2 to which the sensor device 10 is attached is referred to as “paper diaper 210 with sensor”.

Guide part 20,20 'is comprised as a pattern displayed on the non-skin surface side of the cover sheet 2b. For example, various patterns such as contour lines, arrows, and cross marks (so-called “dragonflies”) of the sensor devices 10 and 10 ′ can be used for the guide units 20 and 20 ′.
However, the guide units 20 and 20 ′ are not limited to the picture, and a guide structure such as a concave portion or a broken line having a size corresponding to the sensor device 10 or 10 ′ may be adopted in the guide units 20 and 20 ′.

  In addition, the guide units 20 and 20 ′ are configured so that the sensor devices 10 and 10 ′ are configured to perform communication with the reception unit 90A of the repeater 90 by wireless communication using medium waves or short waves. Alternatively, it is configured as a medium wave / short wave transmissive guide portion that transmits a short wave. With such a configuration, the repeater 90 can satisfactorily receive the detection information from the sensor devices 10 and 10 '.

[2. Sensor device]
As shown in FIGS. 2 and 3, 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 planar 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, the hook material is provided on one of the cover sheet 2b and the attachment portion 12, and the loop material is provided on the other. By using the surface 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 or an adhesive tape 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 positioned by the guide part 20 in the crotch 2 </ b> B of the paper diaper 2 and attached to 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 of the disposable diaper 2 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 disposable diaper 2 from which urine is excreted, it is preferable to provide the housing 11A with water resistance, water repellency, and ammonia resistance. 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 visibility, the housing 11A may be provided with phosphorescent property, fluorescence property, or light emission property.

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.
2 and 3 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.
Specifically, from the viewpoint of suppressing discomfort to the wearer, the width of the apparatus main body 11 is usually 1 to 50 mm, preferably 1 to 40 mm, more preferably 1 to 30 mm, and the longitudinal dimension is usually 1 to 100 mm. Preferably it is 1-70 mm, More preferably, it is 1-50 mm, and a thickness dimension is 1-30 mm normally, Preferably it is 1-20 mm, More preferably, it is 1-15 mm.
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.
2 and 3 exemplify the attachment part 12 that is X-shaped in plan view and covers most of the apparatus main body part 11.

  However, the attachment portion 12 having various shapes and sizes can be employed 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 a 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 higher air permeability than the paper diaper 2 in at least a part of the ventilation region R _V in order to suppress a decrease in air permeability due to attachment of 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. Therefore, 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. 4, 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. In FIG. 4, the thickness is exaggerated for easy understanding of the configuration of the attachment portion 12.

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 region of the attachment portion 12 is the ventilation region R _V , the two-layered breathability in which the breathable layer 12 a and the adhesion layer 12 b are laminated is higher than the breathability of the disposable diaper 2. For example, the air permeability of the ventilation layer 12 a is set higher than that of the adhesion layer 12 b, and the air permeability of the adhesion layer 12 b 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. Moreover, you may use as a ventilation layer 12a what gave the air permeability by giving a process, such as punching, to a material with no air permeability or low. 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.

Further, from the viewpoint of improving the visibility, the mounting 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.

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, it is possible to ensure the accuracy of the excretion information, and more specifically, it is possible to estimate the type and properties of the excrement.

  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 the 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, part or all of each function may be realized by hardware (electronic circuit), or may be realized by using software and hardware together.

<Judgment part>
The determination unit 111 determines the wearer's excretion time based on the amount of change in humidity and 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 increase in excretion is set in advance experimentally or empirically.
Accordingly, the “excretion increase degree” of the condition A1 is larger than the increase degree of humidity / temperature in the disposable diaper 2 immediately after the replacement as the 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. Thereafter, the humidity and temperature are maintained at almost constant values. At the time of excretion, the humidity / temperature values are further increased from the fixed values. Therefore, in order to determine the latter rise while eliminating the former rise, a predetermined rise 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 / temperature that is maintained immediately after the disposable diaper 2 is changed and is increased, 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.
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 humidity / temperature fluctuations is satisfied, the determination unit 111 can determine that it is the 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 degree of replacement decrease and the predetermined decrease value of these conditions B1 and B2 are also set in advance experimentally or empirically as determination threshold values or determination values.
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 “category 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 watery feces (first fluid excrement) and urine feces (second 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 urine stool diffuses more easily than watery stool in fluid excretion, and the temperature tends to decrease (the behavior of humidity and temperature varies depending on the properties). This is a condition set by paying attention to. Note that the “detailed reduction degree” is set to be larger than the above “category reduction 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 types 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”. .
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 the point of excretion are obtained from the determination result in the determination unit 111. The type of excrement is obtained from the classification result in the classification unit 113. As shown in Table 1 below, the wearer's discomfort is determined by the presence / absence of a determination result at the determination unit 111, the elapsed time t measured by the timer 112, and the type of excrement classified by the classification unit 113. Calculated based on

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 very uncomfortable state. 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 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 preset experimentally or empirically 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 excrement of fluid is excreted, so that a decrease in comfort due to a decrease in temperature can be suppressed. However, since the solid excrement is not absorbed by the absorbent body 2a and continues to be interposed between the disposable diaper 2 and the wearer, 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. Repeater]
The repeater 90 has a function of receiving detection information (atmosphere information) transmitted from the sensor device 10 via the wireless line 40 at the receiving unit 90A, and transmitting the received detection information to the computer 100 wirelessly or by wire. Have. As described above, the detection information of the sensor device 10 is transmitted to the computer 100 via the relay 90 (relay).
In the present embodiment, since the receiving unit 90A is integrated with the repeater 90, in the description of the arrangement state, in the case of the repeater 90 and the receive unit 90A of the repeater 90, The meaning is the same.
Further, the repeater 90 may have a function of displaying the detection information transmitted from the sensor device 10 and a function of displaying a change in the detection information with time.

A plurality of receiving units 90A of the repeater 90 are arranged in a room (space) where the wearer stays. Specifically, the receiving unit 90A of the repeater 90 detects atmospheric information from the sensor device 10 attached to the diaper 2 worn by the wearer at at least one position among a plurality of positions in the room. At least one is provided at each position corresponding to a plurality of positions in the room.
The “room where the wearer stays” here means the inside of a room in a facility where a plurality of wearers (care recipients) such as a care facility and a hospital stay. The interval between the repeaters 90 installed in the room is not particularly limited. The interval between the repeaters 90 (hereinafter, the term repeater 90 in this embodiment is synonymous with the receiving unit 90A of the repeater 90) is, for example, the number of care recipients staying indoors, the care recipients. The action range, the moving speed, the arrangement of obstacles (for example, furniture, etc.) that may hinder the reception of detection information, and the like are set as appropriate. The directions in the room where the wearer stays are defined as “gravity direction”, “first direction”, and “second direction”. A direction orthogonal to the direction of gravity is referred to as a “first direction”, and a direction orthogonal to the direction of gravity and the first direction is referred to as a “second direction”.

Depending on the positional relationship between the repeater 90 and the wearer's own body (particularly the thigh) and the arrangement of obstacles, the repeater 90 may not easily receive the detection information. For example, in a state where the wearer is walking in the room (the wearer's traveling direction is the first direction), the detection information transmitted from the sensor device 10 is obstructed by the wearer's own body, and the gravity direction It is difficult for the repeater 90 located above or in the second direction to receive. In this case, the reception accuracy of the detection information is maintained by receiving the detection information by the repeater 90 located in the first direction (particularly, the wearer's traveling direction, that is, the front) or the gravity direction. In the state where the wearer is lying on his / her back on the bed (the direction in which the head and the toes are connected is the first direction), the detection information is one of the first directions (the head side) and the second. The repeater 90 located in the direction is difficult to receive. In this case, the reception accuracy is maintained by receiving the detection information by the repeater 90 located in the other side (toe side) of the first direction and the gravity direction.
That is, at least one repeater 90 is provided at each position corresponding to a plurality of positions where the detection information from the sensor device 10 can be detected in the room where the wearer stays, so that the detection information can be received efficiently. Therefore, the reception accuracy of detection information is maintained.
As a result, the accuracy of detection information input to the computer 100 via the repeater 90 is improved.

Further, the repeater 90 detects the atmosphere information from the sensor device 10 at at least one of a plurality of positions with respect to a certain place in the space when the wearer is staying at a certain place in the space. Therefore, a plurality are provided. In other words, in accordance with the above example (a state where the wearer is lying on his / her back on the bed), when the wearer is staying on the bed, that is, when the wearer is sleeping on his / her back on the bed, At least one of a plurality of positions (positions in the first direction, the second direction, and the gravity direction) (the other in the first direction (toe side) and the position in the gravity direction) detects the atmosphere information. A plurality are arranged so as to be able to.
As described above, by providing a plurality of repeaters 90 capable of detecting the atmosphere information at the place where the wearer stays, the reception accuracy of the atmosphere information is improved.

Further, at least some of the repeaters 90 of the plurality of repeaters 90 are provided at positions below the sensor device 10. By installing at least a part of the repeaters 90 below the position of the sensor device 10, the detection information transmitted from the sensor device 10 is less likely to be blocked by the wearer's own body (particularly the thigh). That is, the repeater 90 can easily receive the detection information. Therefore, the accuracy of the detection information input to the computer 100 is further improved.
Note that “below the sensor device 10” means a position lower in the direction of gravity than the crotch 2B to which the sensor device 10 is attached. For example, when the wearer is standing or sitting, the repeater 90 is provided on the wall or floor at a position lower in the direction of gravity than the wearer's crotch 2B, and the wearer is sleeping ), A repeater 90 is provided on the floor. When the wearer's stay space is in a common room such as a facility, the wearer often sits in a chair (sitting position), so the wall or floor lower than the seat surface of the chair The repeater 90 is embedded in As described above, the repeater 90 is appropriately disposed according to the posture of the wearer, that is, the position of the sensor device 10.
The remaining repeaters 90 are installed at the same height as the sensor device 10 or above the sensor device 10. The ratio at which the repeater 90 is arranged above and below the sensor device 10 is appropriately set according to the behavior pattern of the wearer in the room, the arrangement of obstacles, and the like.
All the repeaters 90 may be installed below the sensor device 10.

  In addition, at least some of the repeaters 90 of the plurality of repeaters 90 are embedded in walls and / or floors that form a space where the wearer stays. The repeater 90 embedded in the wall or floor can satisfactorily receive detection information from the sensor device 10 located within a predetermined range without obstructing the wearer's movement. From such a viewpoint, it is preferable that all the repeaters 90 are embedded in the wall and / or floor of a facility or the like.

  The wireless line 40 between the sensor device 10 and the repeater 90 is a wireless line using a medium wave or a short wave. That is, the sensor device 10 transmits the detection information to the repeater 90 by wireless communication using a medium wave or a short wave. The medium wave is a radio wave having a frequency of 300 kHz or more and less than 3 MHz, and the short wave is a radio wave having a frequency of 3 MHz or more and less than 30 MHz. Medium waves or short waves have the property of not being easily blocked by the human body. With a wireless line using medium waves or short waves, preferably a wireless line using medium waves, the repeater 90 can receive the detection information transmitted from the sensor device 10 with high accuracy. Therefore, the accuracy of the detection information input to the computer 100 is further improved.

Hereinafter, an example in which the information processing system 30 is applied to a facility such as a care facility or a hospital will be described. In the information processing system 30 illustrated in FIG. 11, a plurality of repeaters 90 are connected to a cloud computer 100 ′ (computer) functioning as a server, and the sensor device 10 is connected to at least one of the repeaters 90. It has become. And as shown in FIG. 11, the alerting | reporting system 1 is constructed | assembled using the information processing system 30 which makes | forms the network topology of such a tree structure. In addition to the information processing system 30, the notification system 1 includes a notification device 130 ′ (notification unit) connected to the cloud computer 100 ′. Here, as the notification device 130 ′, a stationary or mobile personal computer 130A ′, a multifunctional mobile terminal 130B ′ such as a so-called tablet or smartphone, and the like can be cited.
In addition, in FIG. 11, each sensor apparatus 10 is distinguished and shown with code | symbol 10A-10G. Moreover, when distinguishing each repeater 90, it demonstrates using the code | symbol 91-94, and when distinguishing the receiving part 90A of each repeater 90, it demonstrates using code | symbol 91A-94A.

In the information processing system 30, the paper diaper 210 with a sensor is attached to each of a plurality of care recipients (wearers). In addition, a plurality of repeaters 90 are installed in each space (points different from each other) where a group of care recipients can stay. For example, as shown in FIG. 11, a first repeater 91 and a second repeater 92 are installed in a bedroom L ₁ (first point) of a quadruple room, and a cafeteria L ₂ (second point) adjacent to the bedroom L _1. 3), the third repeater 93 and the fourth repeater 94 are installed. In FIG. 11, a care recipient who wears each of the four paper diapers 210 </ b> A to 210 </ b> D with sensors is staying in the bedroom L <b> ₁ , and a caregiver who wears each of the three paper diapers 210 </ b> E to 210 </ b> G with a sensor is Illustrate the situation of staying at ₂ .

For example, if the first sensor with a disposable diaper 210A is mounted to the first care recipient bedroom L _1, the first sensor device 10A attached to the paper diaper 2A detects the humidity and temperature of the paper diaper 2A, the detection Information is transmitted to the first repeater 91 wirelessly using medium waves or short waves. Similarly, the third sensor with the disposable diaper 210C Third care recipient bedroom L ₁ and is mounted, the third sensor unit 10C attached to the paper diaper 2C detects the humidity and temperature of the paper diaper 2C, this The detection information is transmitted to the second repeater 92 by radio using a medium wave or a short wave.
In addition, a conditioned fifth sensor diapers 210E is mounted on the fifth care recipient canteen L _2, the fifth sensor unit 10E attached to the paper diaper 2E detects the humidity and temperature of the paper diaper 2E, the detection Information is transmitted to the third repeater 93 wirelessly using medium waves or short waves. Similarly, the sixth care recipient canteen L ₂ and with the sixth sensor diapers 210F is mounted, the sixth sensor device 10F attached to the paper diaper 2F detects the humidity and temperature of the paper diaper 2F, the The detection information is transmitted to the fourth repeater 94 wirelessly using a medium wave or a short wave.
Here, the first relay 91 is embedded in the floor of the bedroom L _1, the second repeater 92 is embedded in the ceiling of the bedroom L _1. The third relay 93 is embedded in the floor of the canteen L _2, the fourth repeater 94 is embedded in the ceiling of the dining room L _2.

The repeaters 91 to 94 have a function of displaying the detection information transmitted from the sensor device 10, and display the change over time of the detection information corresponding to each care recipient as it is.
The repeaters 91 to 94 transmit information transmitted from the plurality of sensor devices 10 to the cloud computer 100 ′ wirelessly or by wire. Thus, the detection information of the sensor device 10 is transmitted to the cloud computer 100 ′ via (relays) the relays 91 to 94.

Further, identification information of the relays 91 to 94 (unique relays) passed through is associated with each detection information transmitted from the relays 91 to 94 to the cloud computer 100 ′. For example, the detection information of the third sensor device 10C is transmitted to the cloud computer 100 ′ together with the identification information of the second repeater 92.
The cloud computer 100 ′ includes an operation unit 110 ′ having at least the above-described functions, a determination unit 111 ′, a timer 112 ′, a classification unit 113 ′, a memory 120 ′, and the like.

  The calculation unit 110 ′ estimates the position of the care recipient who wears the paper diaper 2 to which the corresponding sensor device 10 is attached based on the identification information associated with the transmitted detection information. Specifically, the calculation unit 110 ′ estimates that the care recipient is located at a location where the repeater 90 is installed through the detection information of the sensor device 10 or in the vicinity (predetermined range).

On the contrary, if the detection information of the predetermined sensor device 10 is not transmitted to the cloud computer 100 ′, a care recipient corresponding to the predetermined sensor device 10 is located at or around the point where the repeaters 91 to 94 are installed. Estimated not.
Specifically, when the sensor device 10 that is the information transmission source is stored in the memory 120 ′ of the cloud computer 100 ′ and the detection information of the sensor device 10 stored in the memory 120 ′ cannot be obtained, the sensor device 10 is supported. The computing unit 110 ′ estimates that the care recipient who is in need does not exist within the range in which the detection information can be transmitted to the repeaters 91 to 94.

[4. Information system]
The notification system 1 includes the information processing system 30 and a notification device 130 (notification unit) that notifies information (excretion information) calculated by the calculation unit 110.

[4-1. 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 or a light that is visually displayed (notified), a sound generator such as a speaker or buzzer that is visually notified, and a vibrator (vibrator) that is tactilely notified. It is done. Further, as illustrated above, a notification device such as a personal computer or a multi-function mobile terminal can be used as the notification unit 130.
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 10 is transmitted from the computer 100 to the notification unit 130.
Examples of the caregiver notified by the notification unit 130 include a caregiver, a helper, and a relative who care for or raise a wearer such as an adult or an infant.

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 according to 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 excretion information, a display order thereof, and a display of some of the various 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 ascending order or descending order display (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.

[5. Notification method]
Next, a notification method will be described with reference to the flowchart of FIG. This notification method includes a method (information processing method) for performing information processing by the information processing system 30 described above, and is a method for performing notification by the notification system 1 described above.
In this notification method, the sensor device 10 detects a humidity / temperature of the disposable diaper 2 (step A10), and a plurality of relays installed in the room where the wearer stays in the humidity / temperature detected in the detection process. Relay step (step A20) that at least one of 90 receives and transmits to the next calculation step, calculation step (step A30) for calculating excretion information based on the humidity / temperature fluctuation received from this relay step, this Each step is performed in the order of the notification step (step A40) for notifying the wearer or caregiver of the excretion information calculated in the calculation step.
In the information processing method, each process is performed in the order of the detection process (step A10), the relay process (step A20), and the calculation process (A30).

Next, the calculation process will be described in detail with reference to FIG.
The initial values of the flags F ₁ , F ₂ , F ₂₁ and F ₂₂ and the elapsed time t used in FIG. 9 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 A31) is first performed. In this determination step, it is determined whether or not the flag F ₁ is “1”. That is, the determination unit 111 determines the excretion time.
When the excretion time is determined in this determination process (F ₁ = 1), the process proceeds to the measurement process (step A32). On the other hand, if the excretion time is not determined in the determination step (F ₁ = 0), the discomfort level flag F ₂ is set to “0” (step A39).

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 A33). 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 A34). On the other hand, when the type of excrement is classified as a solid in the classification process, the second discomfort level flag F ₂₂ is set to “2” regardless of the elapsed time t (step A37).

If the elapsed time t has not exceeded the predetermined time t _P, set the first unpleasantness flag F ₂₁ to "1" (step A35), the elapsed time t is equal to the predetermined time t _P above, first unpleasantness the flag F ₂₁ is set to "2" (step A36).
Then, the logical sum of the two flags F ₂₁ and F ₂₂ set after the classification process is set in the discomfort level flag F ₂ (step A38).
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.

[6. 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 time t ₀ until the replacement of the disposable diaper 2, as shown in FIGS. 10 (a) and 10 (b), the humidity h and 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 level, and are lower than 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 the 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 time 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 at 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. 10C, the excretion flag F ₁ is set from “0” to “1”. Also, as shown in FIGS. 10D and 10F, 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. 10 (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. 10B, 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. 10E, the second discomfort level flag F ₂₂ is set from “0” to “2”. Therefore, as shown by a two-dot chain line in FIG. 10F, the discomfort level 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. 10D and 10F, the discomfort level flags F ₂ and F ₂₁ are set from “1” to “2”.

[7. Action and effect]
Since the present embodiment is configured as described above, the following operations and effects can be obtained.

The accuracy of information is improved. That is, according to this information processing system, the detection information from the sensor device 10 can be appropriately received.
(2) Since the detection information of the sensor device 10 is transmitted to the computer 100 via the repeater 90, battery performance and information transmission distance required for the sensor device 10 can be suppressed. Therefore, the sensor device 10 can be reduced in size and cost. Thereby, useful information for a wearer and its caregiver can be provided based on information detected by the sensor device 10 while suppressing a sense of discomfort for the wearer wearing the paper diaper 2 to which the sensor device 10 is attached. .

[7-2. Paper diaper]
(1) Since the paper diaper 2 includes the first guide portion 20 for attaching the sensor device 10 to a predetermined position, the sensor device 10 can be easily positioned and attached. According to the paper diaper 2 in which the sensor device 10 is attached to the crotch 2B, the pressure and friction of the wearer's skin by the sensor device 10 are suppressed, so that the occurrence of bed slip can be prevented. Moreover, since the guide part 20 is provided in the approximate middle of the urethral opening facing part 22 and the anus facing part 21, the sensor apparatus 10 can detect solid excretion and fluid excretion with good balance.
(2) Moreover, the disposable diaper 2 provided with 2nd guide part 20 'different from 1st guide part 20 can position and attach sensor apparatus 10 and sensor apparatus 10' easily.

The configuration of each sensor device can be changed in accordance with the properties of the excrement so as to detect the excrement. Therefore, the detection accuracy of each sensor device can be improved, and the size of each sensor device can be reduced.

[II. Second embodiment]
Next, the sensor device of the second embodiment and the absorbent article 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. 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 structure is demonstrated in order of a sensor apparatus and an absorbent article.

[1. Sensor device]
As shown in FIG. 12, the absorbent article 4 to which the sensor device 7 of the present embodiment is attached is provided with a water-absorbing urine pad 6 (interior body) in addition to a paper diaper 5 (outer body). That is, the absorbent article 4 is a composite of the urine pad 6 and the paper diaper 5. The 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”. Examples of the exterior body include a paper diaper, an underwear, and a cloth-made pant-type exterior body called holder pants made for holding a urine pad. The interior body is not particularly limited as long as it has water absorption.

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. 12, 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. As described above, according to the sensor device 7 that detects only humidity and temperature, the sensor device 7 itself can be downsized and the program can be simplified. As a result, the durability of the sensor device 7 and the availability (reliability) of the program can be improved. 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 sensor device 7 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 hook-and-loop fastener 79 provided 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.
Further, in order to connect the housing of the sensor device 7 and the paper diaper 5, a separate tape (connection 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 to the repeater 90 at a predetermined cycle. The 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. Here, a “predetermined position” is set in the crotch part 5 </ b> B of the paper diaper 5. Specifically, the guide part 51 is provided in the center region on the skin surface side of the crotch part 5B of the paper diaper 5, that is, on the skin surface side of the paper diaper 5 and including the center. By providing the guide part 51 in the paper diaper 5, the positioning and attachment of the sensor device 7 is facilitated.

  Further, as shown in FIG. 12, the paper diaper 5 has a sensor device 7 ′ (also referred to as “second excretion detection device”) that is different from the sensor device 7 (also referred to as “first excretion detection device”). A second guide part 51 ′ for attaching may be provided. The second guide portion 51 'is provided in an end region on one side of the crotch part 5B in the longitudinal direction L (front body 5A direction), specifically, a region including the urethral opening facing portion. By providing the second guide portion 51 ′ on the paper diaper 5, the positioning and attachment of the sensor device 7 ′ is facilitated. When the sensor devices 7 and 7 'are attached to the paper diaper 5, the sensor device 7 near the anus facing portion detects the humidity and temperature related to solid excrement such as feces, and the sensor device 7' near the urethra mouth facing portion is detected. Detect humidity and temperature related to fluid excrement such as urine. Thus, by separating the properties of excrement detected by the sensor devices 7 and 7 ′ according to the attachment position, the configuration of each sensor device can be simplified, and the detection accuracy of each sensor device can be improved. In addition, the size of the sensor device itself can be reduced, and the discomfort for the wearer can be further reduced.

  The paper diaper 5 may be provided with a third guide portion 54 for attaching the urine pad 6. The 3rd guide part 54 is provided in the both ends of the skin surface side in the longitudinal direction L and the width direction W of the paper diaper 5, for example. By providing the third guide portion 54 on the paper diaper 5, it becomes easy to position and attach the urine pad 6 to the paper diaper 5.

Guide part 51,51 ', 54 is comprised as a pattern displayed on the skin surface side of the paper diaper 5. As shown in FIG. For example, various patterns such as an outline, an arrow, and a cross mark (so-called “dragonfly”) of the sensor device 7 can be used for the guide portions 51, 51 ′, and 54.
However, the guide portions 51, 51 ′, 54 are not limited to pictures, and a guide structure such as a concave portion or a broken line corresponding to the sensor device 7, 7 ′ or the urine pad 6 is adopted for the guide portions 51, 51 ′, 54. May be.

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 parts 73 and 52 are the shortest path connecting the coupling part 73 and the second coupling part 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.

  As shown in FIG. 12, when the sensor device 7 ′ is attached to the paper diaper 5, the coupling portion of the sensor device 7 ′ and the second coupling portion 52 may be coupled using a strap 8 ′. . Moreover, you may provide the coupling part different from the 2nd coupling part 52 in the paper diaper 5. FIG.

  The said absorbent article 4 can be used for the information processing system and alerting | reporting system which were demonstrated by 1st embodiment. In other words, in this case, the sensor device 7 and the sensor device 7 ′ communicate with the receiving unit 90A of the repeater 90 using different frequencies, or the sensor device 7 and the sensor device 7 ′ identify the sensor devices. Communication is performed between the sensor devices 7 and 7 ′ and the receiving unit 90 </ b> A of the repeater 90. The processing after reception by the repeater 90 can be applied to the information processing system and the notification system described in the first embodiment.

[3. Action and effect]
Since the present embodiment is configured as described above, the following operations and effects can be obtained.
(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 attached to the guide part 51 provided in the skin surface side with respect to the paper diaper 5, it does not expose outside but 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. Moreover, since the guide part 51 is provided in the crotch part 5B, the pressure and friction of a wearer's skin by the sensor apparatus 7 attached to the guide part 51 are suppressed. As a result, the occurrence of bedsores can be prevented. Moreover, since the guide part 51 is provided in the approximate middle between the urethral opening facing part and the anus facing part, the sensor device 7 can detect solid excretion and fluid excretion with a good balance.

  (2) Moreover, according to the paper diaper 5 which attached sensor apparatus 7 'in addition to the sensor apparatus 7, the structure of each sensor apparatus can be changed according to the property of excrement. Therefore, the detection accuracy of each sensor device can be improved, and the size of each sensor device can be reduced.

  (3) 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.

(4) 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. .
(5) Since the sensor device 7 is attached to the paper diaper 5 in a state where the detection unit 71 is 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.

(6) Since the guide unit 51 that guides 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.
(7) 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.

(8) 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.
(9) Since the second coupling portion 52 is disposed 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.

  (10) 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 shape 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.

  (11) Further, by using the absorbent article 4 in the information processing system or the notification system described above, the information transmitted from the sensor devices 7 and 7 ′ can be easily received by the repeater 90, and the accuracy of the detection information is improved. To do. That is, according to this information processing system, it is possible to appropriately receive the detection information from the sensor devices 7 and 7 '.

[III. 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 devices 10 and 10 ′ are attached. In such a paper diaper 2, in order to ensure the detection accuracy of the sensor devices 10 and 10 ′, the apparatus main body 11 is attached to the skin surface side of the paper diaper 2 arranged on the outside (non-skin surface side) of the urine pad. 12 is attached. 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 devices 10 and 10 ′ used in this way, the detection accuracy in the detection unit 11 a is ensured by including in the ventilation region R _{V the} region of the attachment unit 12 that covers the detection unit 11 a from the skin surface side. be able to.

Moreover, as shown in FIG. 13, you may use attachment part 11 'by which adhesion layer 12b' was laminated | stacked on some ventilation layer 12a '. In FIG. 13, the thickness of the attachment portion is exaggerated for convenience of illustration.
FIG. 13 illustrates a case where 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 portion 11 ′ in which the adhesion layer 12b ′ is laminated on a part of the ventilation layer 12a ′, the breathability can be improved in the other portion of the ventilation layer 12a ′, and the comfort of the wearer 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 ventilation hole 13 ′ may be provided in the attachment portion 11 ′. FIG. 13 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 improved reliably, and the deterioration of the wearer's comfort can be further suppressed, which contributes to weight reduction.

  Further, in the absorbent article 4 shown in FIG. 12, the sensor described in the first embodiment is provided on the outer surface (most non-skin surface side) of the paper diaper 5 instead of one or both of the guide portions 51 and 51 ′. You may provide the guide parts 20 and 20 '(refer FIG.1, 2) for attaching apparatus 10,10'.

In addition, a sensor device different from the sensor devices 7, 7 ′, 10, 10 ′ may be attached to one paper diaper 2, 5. In this case, it is preferable that the sensor device is attached to a portion overlapping with the absorber 2a in plan view.
As described above, the sensor device is attached to a location different from the guide portions 20, 20 ′, 51, 51 ′, so that the region where excrement is excreted in the disposable diaper 2 can be detected in detail. Furthermore, the calculation units 110 and 110 ′ may classify the types of excrement according to the excretion area of the excrement. 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.

  The atmosphere information that is the detection target of the sensor devices 7, 7 ′, 10, 10 ′ is not limited to humidity and temperature as described above, but is variously detected by changes in electrical characteristics such as odor and color of excrement. It may be the information. The sensor device 7, 7 ', 10, 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, 7 ', 10, 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 the predicted material, the guidance to the toilet for each wearer, the timing of replacement of the disposable diaper 2 or the absorbent article 4, The order can also be optimized.

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 variation-
In the first modification, on the premise that the temperature detected by the sensor devices 7, 7 ′, 10, 10 ′ is satisfied to rise beyond a predetermined range within a predetermined period, the sensor devices 7, 7 ′, The types of excreta are classified according to the degree of increase in the humidity detected at 10, 10 ′ (hereinafter abbreviated as “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” 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 modification, on the premise that the temperature detected by the sensor devices 7, 7 ′, 10, 10 ′ is equal to or higher than a predetermined value, the humidity detected by the sensor devices 7, 7 ′, 10, 10 ′. The type of excreta is classified according to height.
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. From the viewpoint of accurately classifying the presence or absence of excretion, the “predetermined value” is as high 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.

  Further, in order to manage nursing care records, excretion records, childcare records, childcare records, etc., the notification system 1 displays various data such as detected atmosphere information, excretion points, and discomfort levels 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 more than that of the disposable diaper 2. Also in this case, it is possible to suppress a decrease in the air permeability of the disposable diaper 2 due to the attachment of the sensor devices 10 and 10 ', and it is possible to ensure the wearer's comfort.

Further, the receiving unit 90A and the repeater 90 may be separated (see FIG. 14). Further, a plurality of receiving units 90A may be provided for one repeater 90 (see FIG. 15).
