Description

  The present invention relates to a diaper that transmits a signal related to excretion of a diaper wearer, and an excretion information distribution system that includes an excretion detection server that generates excretion information based on a signal from the diaper and transmits the excretion information to an information distribution terminal.

  Even if an infant or an elderly person wearing a diaper is excreted in the field of childcare or nursing care, a caregiver such as a guardian or a caregiver cannot immediately know and cannot be separated from the diaper wearer. Therefore, the person who takes care needs to confirm the presence or absence of excretion periodically every 1 to 2 hours, for example, and is restricted in time and has high mental stress. At the same time, stress is generated on the side that is regularly checked. Moreover, since absorbent articles, such as a diaper, are designed on the assumption that there is a minimum of 2-3 urinations, there is a limit to reducing the thickness.

  Patent Document 1 has a sensor unit, an IC chip, and an antenna, and stores the sensor detection signal received from the diaper that transmits the sensor detection signal and the diaper via the repeater, and the stored detection signal. An excretion detection device is described that outputs a notification signal when the time change pattern corresponds to a previously registered pattern.

JP 2006-296666 A

  The diaper described in Patent Document 1 is a method of receiving a driving power radio wave and supplying power to an IC chip or a sensor unit as a power source, or a battery pad attached to an outer surface of a diaper with an adhesive tape or the like. The method is adopted. In the case of receiving driving power radio waves and supplying power to the IC chip or the sensor unit, it is necessary to install a transmitter that transmits the driving power radio waves around the diaper wearer. In addition, there is a problem that it cannot be used on the go. Further, in this case, the IC chip needs to have a function of receiving driving power radio waves and a function of converting driving power radio waves to DC power. On the other hand, when the battery pad is installed by being attached to the outer surface of the diaper with an adhesive tape or the like, it is necessary to stick the battery pad against the fastener on the outer surface of the diaper every time the diaper is mounted. Moreover, since a battery pad is mounted on the outer surface of the diaper, there is a possibility that the diaper wearer may feel uncomfortable and the wearability is reduced.

  The present invention is a diaper that detects excretion of a diaper wearer and transmits a signal, has a disposable power supply, and is highly excitable and can be used even on the go. It is an issue to provide an excretion detection server that promptly informs parents and caregivers that there has been, and to provide an excretion information distribution system that reduces stress on those who care for diaper wearers. To do.

In one aspect of the present invention, the diaper includes an electrode, and a battery that generates electricity using urine, and a transmission unit that transmits a signal to the communication unit using the electricity generated by the battery. , and a brine supply unit for supplying a saline solution to the battery when the diaper worn, the battery is Ru generates electricity using the saline at the time the diaper worn.

The diaper uses the urine excreted by the diaper wearer to generate electricity, and uses this to transmit a signal to the communication unit. Thereby, the information regarding a diaper wearer's excretion can be transmitted outside. In addition, since power can be generated in the diaper, the reception function of the diaper main body and the equipment such as a transmitter installed around the diaper wearer are not required, and it can be used even when away from home. Moreover, since it is not necessary to attach a power source such as a battery pad when the diaper is mounted, the mounting property is improved. In addition, when the power source uses only urine to generate electricity, if the diaper wearer excretes stool before excreting urine, no electricity is generated and the diaper wearer excretes stool. Cannot be sent to the outside. In this diaper, when the diaper is mounted, the saline solution supply unit supplies the saline solution to the power source unit, and the power source unit generates electricity using this, so that power can be supplied from when the diaper is mounted.

In another aspect of the present invention, the diaper includes an electrode, a battery that generates electricity using urine, and a transmission unit that transmits a signal to the communication unit using the electricity generated by the battery.

The diaper uses the urine excreted by the diaper wearer to generate electricity, and uses this to transmit a signal to the communication unit. Thereby, the information regarding a diaper wearer's excretion can be transmitted outside. In addition, since power can be generated in the diaper, the reception function of the diaper main body and the equipment such as a transmitter installed around the diaper wearer are not required, and it can be used even when away from home. Moreover, since it is not necessary to attach a power source such as a battery pad when the diaper is mounted, the mounting property is improved. Moreover, when a diaper wearer excretes urine, urine penetrates into the inner surface, and the first power supply unit generates electricity, which is used to transmit a signal to the communication unit. Thereafter, when the wearer further excretes urine, the urine penetrates to the outer side surface, and the second power source generates electricity, which is used to transmit a signal to the communication unit. Thereby, not only that there was excretion but also that the urine has penetrated to the outer surface of the diaper can be transmitted to the outside.

In one aspect of the diaper, the sensor further includes a sensor that creates sensor detection data, and the transmission unit transmits the sensor detection data to the communication unit by the signal. In this aspect, for example, the sensor detects a state in the diaper such as temperature and humidity, creates sensor detection data, and the transmission unit transmits the sensor detection data to the communication unit. Thereby, the information which shows the state in a diaper can be transmitted outside.

In one aspect of the diaper, the diaper further includes a power supply unit that stores electricity generated by the battery. In this aspect, electricity generated by using urine excreted by the diaper wearer can be efficiently used.

In one aspect of the diaper, the battery constitutes a voltaic battery that uses a component contained in urine as an electrolyte, and forms a double tank structure. In this aspect, even if the electric power generated in the single tank voltaic battery does not satisfy the necessary minimum power for transmitting a signal to the communication unit, the required electric power can be ensured by using the double tank structure. As a result, an inexpensive metal combination such as copper and aluminum can be used for the electrodes of the voltaic battery, and the cost can be reduced.

In one aspect of the diaper, a voltaic battery that uses a component contained in urine as an electrolyte is configured, and the electrode partially includes a different metal. The voltage generated in the voltaic battery differs depending on the combination of metals used for the electrodes. In this aspect, the required power for transmitting a signal to the communication unit can be ensured by using a combination of metals that generate a high voltage for a part of the electrodes. Moreover, even if the high voltage generated metal is an expensive metal, the cost can be reduced by using a part of the metal by spraying it in a minute amount. Furthermore, this eliminates the need for a multi-tank structure, so that the power supply unit can be made smaller.

Then, the excretion detection server transmits the excretion information to the information terminal device. This excretion information distribution system does not require the reception function of the diaper main body or the transmitter and other equipment installed around the diaper wearer, so it can be used on the go, and the battery pad or other power source is attached when the diaper is attached. There is no need to do. In addition, possession of information terminal devices by caregivers such as infant guards and elderly caregivers, it is possible to know the excretion information of diaper wearers even when they are not there. Reducing the restraint time of those who do. Furthermore, if it is assumed that the diaper will be replaced at the time of excretion, the thickness of the diaper can be made thinner than before, and skin problems caused by prolonged contact with urine, stool, etc. can be reduced.

  Hereinafter, embodiments for carrying out the present invention will be described with reference to the drawings.

  In FIG. 1, the conceptual diagram of the excretion information delivery system 100 is shown. In the present embodiment, the excretion information distribution system 100 includes a diaper 1, a communication unit 2, an excretion detection server 3, and an information distribution terminal 4. For reference, FIG. 1 also shows a closed diaper 1x. The diaper 1 and the communication unit 2, the communication unit 2 and the excretion detection server 3, and the excretion detection server 3 and the information distribution terminal 4 can communicate with each other wirelessly.

  The diaper 1 includes an active tag 11, a battery 12, and a temperature sensor 13. An active tag is an IC tag that operates with its own power supply, unlike a passive tag that does not incorporate a battery.

  The battery 12 is a voltaic battery including two electrodes each formed of metals having different ionization tendencies, and uses the urine excreted by the diaper wearer as an electrolytic solution to generate power and supply power to the active tag 11.

  The temperature sensor 13 detects the temperature in the diaper 1, creates temperature data (sensor detection data), and transmits it to the active tag 11.

  The active tag 11 temporarily stores the temperature data received from the temperature sensor 13 and transmits it to the communication unit 2 at a predetermined timing, for example, once every 10 seconds. At this time, ID data for identifying the diaper may be added to the temperature data and transmitted. The ID data may be assigned to each diaper and each diaper may be identified individually, or the same ID data may be assigned to all diapers in one case to identify the case. Note that an antenna for transmitting temperature data to the communication unit 2 is connected to the active tag 11 (not shown).

  The communication unit 2 is installed within a predetermined range from the diaper 1 so that a signal from the active tag 11 can be received. In this embodiment, the communication unit 2 is attached to the clothes of the diaper wearer. The communication unit 2 transmits the temperature data received from the active tag 11 to the excretion detection server 3. Moreover, in this embodiment, this transmission is performed by PHS (Personal Handy-Phon System) transmission. Since the transmission output of PHS is much smaller than that of a mobile phone, it can be used in medical institutions.

  The excretion detection server 3 analyzes the temperature data received from the communication unit 2 and determines whether or not the diaper 1 has excreted. If there is excretion, the type of excretion is determined based on the temperature data. Next, the excretion detection server 3 creates excretion information based on the determination result and transmits it to the information distribution terminal 4. Since the excretion detection server 3 is an external server and transmits temperature data from the communication unit 2 by PHS transmission, the excretion information distribution system 100 can be used even when the user is away from home.

  The information distribution terminal 4 is a PC terminal possessed by a guardian if the diaper wearer is an infant, a caregiver if the diaper wearer is a caregiver, or a doctor or nurse if it is a medical institution. And mobile devices. The information distribution terminal 4 outputs the excretion information received from the excretion detection server 3 by screen display or voice, and notifies the excretion information to a guardian, a caregiver, a doctor, a nurse, and the like.

  FIG. 2 is a block diagram showing the configuration of the active tag 11. As illustrated, the active tag 11 includes a power supply unit 111, a control unit 112, a clock circuit 113, an AD conversion unit 114, a ROM 115, a RAM 116, and an RF unit 117. The power supply unit 111 is connected to the battery 12, and the AD conversion unit 114 is connected to the temperature sensor 13. The RF unit 117 is connected to the transmitting antenna 14.

  The power supply unit 111 supplies electric power necessary for operating the active tag 11. In addition, when the capacitor 118 is provided in the power supply unit 111 as in the example of FIG. 2, electricity generated by the battery 12 can be stored in the capacitor 118 and electric power can be output only when necessary.

  The control unit 112 is configured by, for example, a microprocessor and controls each unit in the active tag 11. Specifically, the control unit 112 executes a control program stored in advance in the ROM 115, thereby converting the temperature data transmitted from the temperature sensor 13 from analog data to digital data by the AD conversion unit 114. Processing for temporarily storing the temperature data converted into digital data by the AD conversion unit 114 in the RAM 116, and processing for transmitting the temperature data temporarily stored in the RAM 116 to the communication unit 2 via the antenna 14 by the RF unit 117 And so on.

  The clock circuit 113 outputs a clock signal to the control unit 112. The control unit 112 executes each of the above processes based on this clock signal.

  The AD conversion unit 114 is connected to the temperature sensor 13 and receives temperature data from the temperature sensor 13 as an analog signal. Then, the received analog signal temperature data is converted into a digital signal.

  The ROM 115 stores various control programs executed by the control unit 112. The RAM 116 temporarily stores the temperature data generated by the temperature sensor 13.

  The RF unit 117 is connected to the antenna 14 and transmits temperature data temporarily stored in the RAM 116 to the excretion detection server 3 via the antenna 14. The excretion detection server 3 can determine whether the excretion of the diaper wearer is defecation or urination based on the temperature data time change, which will be described later.

  Next, the structure of the diaper 1 will be described in detail. FIG. 3 is an example of a sectional view and a plan view of the diaper 1. As described above, the present invention is characterized in that the active tag 11 of the diaper 1 operates using electricity generated by the battery 12 using urine. In the present embodiment, a data transmission unit having an active tag 11, a battery 12, a temperature sensor 13, and an antenna 14 is disposed at the center of the diaper 1.

  FIG. 3A is an example of the structure of the diaper 1 in which a set of data transmission units 200 is built. The data transmission unit 200 has a sheet shape and is arranged at the center of the absorbent body of the diaper 1. Thus, when the diaper wearer excretes urine, the urine is supplied to the battery 12, the active tag 11 is operated by the electricity generated by the battery 12, and the temperature data detected by the temperature sensor 13 is transmitted via the antenna 14. It can be transmitted to the communication unit 2.

  However, if the diaper wearer excretes stool before excreting urine, the battery 12 does not generate electricity and the active tag 11 does not start, so the diaper wearer transmits information that excretes feces. I can't. Therefore, in this embodiment, a saline solution supply unit 15 containing a small amount of saline solution designed to be broken when the diaper is worn is installed on the battery 12. When the diaper 1 is attached, the saline solution supply unit 15 supplies a small amount of saline solution to the battery 12, and the battery 12 generates power using this saline solution, and the active tag 11 is activated. Thereby, even when the diaper wearer defecates before urination, it can be transmitted to the excretion detection server 3.

  FIG. 3B shows an example of the structure of the diaper 1 in which two sets of data transmission units 200a and 200b are arranged. The data transmission units 200a and 200b are in the form of a sheet and are arranged one by one at the center of the inner surface that touches the skin of the diaper wearer and at the center of the opposite outer surface. The data transmission unit 200a includes an active tag 11a, a battery 12a, a temperature sensor 13a, and an antenna 14a. The data transmission unit 200b includes an active tag 11b, a battery 12b, a temperature sensor 13b, and an antenna 14b.

  When the diaper 1 is attached, the saline solution supply unit 15 supplies a small amount of saline solution to the battery 12a of the data transmission unit 200a on the inner surface, and the battery 12a generates power using the saline solution, and the active tag 11a is activated. To do. Next, when the diaper wearer excretes urine, first, urine is supplied to the battery 12a of the data transmission unit 200a on the inner surface, and electricity is generated. The active tag 11a uses this electricity to transmit temperature data detected by the temperature sensor 13a to the communication unit 2 via the antenna 14a.

  Thereafter, when the diaper wearer further excretes urine, the amount of urine absorbed by the absorbent body of the diaper 1 increases, so that the urine is also supplied to the battery 12b of the data transmission unit 200b on the outer surface. , Electricity is generated. The active tag 11b uses this electricity to transmit temperature data detected by the temperature sensor 13b to the communication unit 2 via the antenna 14b. Thus, for example, when excretion of stool needs to be exchanged once, but the absorber is designed so that excretion of urine can be absorbed multiple times, how many times the guardian or caregiver urinates Even if it is not known whether or not there is excretion, the temperature sensor 13a on the inner surface can detect the excretion of feces, and the temperature sensor 13b on the outer surface can notify that the urine has penetrated to the outer surface.

  Note that the diaper 1 may be designed so that the active tag 11 can be peeled off when the diaper 1 is discarded, for example, by slitting the base material of the data transmission unit 200 at the place where the active tag 11 is installed.

  Next, the battery 12 will be described in detail. The battery 12 is a voltaic battery. A voltaic battery is a battery that generates an electric current by moving electrons by immersing an electrode using a metal having a large ionization tendency and a metal having a small ionization tendency in an electrolytic solution. In the present embodiment, a combination of aluminum and copper is employed as an electrode, and urine excreted by a diaper wearer is used as an electrolyte. Human urine is about 95% water and contains about 1% to 5% NaCl. That is, a urine component NaCl aqueous solution is used as an electrolytic solution.

  FIG. 4A is a diagram showing a battery 12 which is a single tank structure voltaic battery. The electrode 121 is made of aluminum, and the electrode 122 is made of copper. The electrode 121 and the electrode 122 are connected to the active tag 11. When the electrolytic solution 30 is supplied to the electrodes 121 and 122, electrons move due to the oxidation-reduction reaction, thereby generating a voltage.

  FIG. 4B is a graph of the voltage generated when the voltaic battery having the single tank structure of FIG. 4A is actually installed on the diaper and urine is supplied to the electrode 121 and the electrode 122 as the electrolytic solution 30. . The components of urine used are water: 96.0%, urea: 1.7%, NaCl: 1.5%, and others: 0.8%. The reaction R1 indicates that a voltage of about 0.2 V is generated by touching the electrode 121 and the electrode 122 with sweat by touching the electrode with a hand. Reaction R2 shows that a voltage of about 0.5 V was generated by supplying urine (120 g) to electrode 121 and electrode 122. Reaction R3 shows a state in which the voltage becomes 0 V by applying a load of 300Ω between the electrodes 121 and 122. The reaction R4 shows a state in which the voltage becomes 0 V by applying a load of 1 KΩ between the electrodes 121 and 122. Reaction R5 indicates that a voltage of about 0.5 V was generated by supplying urine (100 g) to electrode 121 and electrode 122. Reaction R6 shows a state where the voltage is about 0.25 V by applying a load of 10 KΩ between the electrodes 121 and 122.

  To activate the active tag 11 of the present embodiment, a voltage of at least 1 V and a current of 1 mA or more are required. However, as shown by reaction R2, even if urine (120 g) is supplied to the aluminum electrode 121 and the copper electrode 122, the generated voltage is about 0.5V.

  FIG. 5A is a diagram showing a battery 12x which is a two-tank structure voltaic battery connected in series. An electrode pair 16a having electrodes 121a and 122b is provided inside the diaper 1, and an electrode pair 16b having electrodes 121b and 122b is provided outside the diaper 1. The electrodes 121a and 121b are made of aluminum, and the electrodes 122a and 122b are made of copper.

  A separator 20 is inserted between the inner electrode pair and the outer electrode pair. The separator 20 is made of a material that does not allow water to pass through, and here, polyvinylidene chloride having a thickness of 11 μm is used. The electrode 121a and the electrode 122b are electrically connected, and the electrode 121b and the electrode 122a are connected to the active tag 11. When the electrolytic solution 31 is supplied to the electrode pairs 16a and 16b, electrons move due to an oxidation-reduction reaction, thereby generating a voltage.

  FIG. 5B shows a case where the two-tank structure voltaic battery of FIG. 5A is actually installed in a diaper and a 2% NaCl solution is supplied as the electrolyte 31 to the electrode pairs 16a and 16b connected in series. It is a graph of the voltage to generate | occur | produce. Reaction R7 shows that a voltage of about 1.2 V was generated by supplying a 2% solution of NaCl (250 ml) to electrode pairs 16a and 16b. Reaction R8 shows a state where the voltage is about 0.4 V by applying a load of 10 KΩ between the electrodes 122a and 121b. The reaction R9 shows a state where the voltage is about 1.2 V by turning off the load 10 KΩ applied between the electrodes 122a and 121b.

  Thus, the voltage 1V required in order to start the active tag 11 is securable by comprising the voltaic battery of the two tank structure connected in series.

  FIG. 6 is an example of a single tank structure voltaic cell in which different metals are used as part of the electrodes. The voltage generated in the voltaic battery differs depending on the combination of metals constituting the electrodes. In the example of FIG. 6, zinc 123 is used for a part of the aluminum electrode 121, and silver 124 is used for a part of the copper electrode 122. As described above, by using metals having different ionization tendencies for a part of the electrodes, it is possible to generate a voltage of about 1 V even in a voltaic battery having a single tank structure. In addition, since silver and zinc are expensive metals, in order to suppress cost, it is good also as, for example, spraying and making it adhere in a trace amount.

  Next, the excretion detection server 3 will be described. When the excretion detection server 3 receives the temperature data from the communication unit 2, the excretion detection server 3 analyzes the temperature data and determines whether or not there is excretion. Moreover, when it determines with having excreted, the kind of excretion is determined based on the time change pattern of temperature data.

  Fig.7 (a) is a time change pattern of the temperature data when a diaper wearer defecates. An arrow 40 is the timing of defecation. Upon defecation, the temperature in the diaper rises rapidly and then levels off.

  FIG.7 (b) is a time change pattern of the temperature data when a diaper wearer urinates. An arrow 41 is the timing of urination. When urinating, the temperature in the diaper rises rapidly and then falls to the right.

  The excretion detection server 3 determines that there is excretion when there is a rapid temperature rise in the temporal change pattern of the temperature data. Further, the excretion detection server 3 stores a defecation time change pattern (FIG. 7A) and a urination time change pattern (FIG. 7B), and stores the temperature data received from the communication unit 2. The type of excretion is determined by comparing with the time change pattern and determining which one corresponds. The excretion detection server 3 creates excretion information that informs the type of excretion and transmits it to the information terminal 4. For example, if the excretion detection server 3 determines that it is urination, the excretion detection server 3 creates excretion information informing that the diaper wearer has urinated and transmits the excretion information to the information terminal 4.

  In addition, the time change pattern of defecation and the time change pattern of urination may differ, for example, when the diaper wearer is an infant and an elderly person, or when the person is a man and a woman. . Therefore, the excretion detection server 3 stores a time change pattern of defecation and a time change pattern of urination for each attribute of the diaper wearer as a condition for analyzing the sensor detection data, and a guardian or a caregiver can store the diaper wearer. The time change pattern of defecation and the time change pattern of urination to be compared may be set to match. Thereby, determination with higher accuracy can be performed.

  Next, the power generation process performed in the diaper 1 will be described. FIG. 8 is a flowchart of the power generation process.

  When the diaper 1 is attached (step S1), the saline solution supply unit 15 is broken and a small amount of saline solution is supplied to the battery 12 (step S2). The battery 12 generates electricity using the saline as an electrolyte (step S3). Next, when urine is excreted by the diaper wearer (step S4), the battery 12 generates electricity using the urine as an electrolytic solution (step S5), and the process ends. When the capacitor 118 is provided in the power supply unit 111, the generated electricity is stored. In the power generation process, step S4 and step S5 are repeatedly executed until the process ends after step S3 is executed.

  Then, the temperature detection process performed in the diaper 1 is demonstrated. FIG. 9 is a flowchart of the temperature detection process.

  When the temperature sensor 13 detects the temperature in the diaper 1 (step S11), the temperature sensor 13 creates temperature data (step S12). The AD conversion unit 114 converts the temperature data created by the temperature sensor 13 from analog data to digital data (step S13). The control unit 112 temporarily stores the temperature data converted into digital data in the RAM 116 (step S14), and ends the process. In the temperature detection process, steps S11 to S14 are repeatedly executed from the start to the end of the process.

  Next, excretion information distribution processing executed in the excretion information distribution system 100 will be described. FIG. 10 is a flowchart of excretion information distribution processing.

  The diaper 1 is designed to periodically transmit temperature data to the communication unit 2, transmits temperature data after a predetermined time has elapsed since the start of processing, and then transmits a predetermined time from the previous transmission. Send temperature data every time.

  In the diaper 1, the control unit 112 of the active tag 11 determines whether or not a predetermined time has elapsed (step S21). The predetermined time is, for example, 10 seconds. If the predetermined time has not elapsed (step S21; No), the process repeats step S21.

  When the predetermined time has elapsed (step S21; Yes), the RF unit 117 transmits the temperature data stored in the RAM 116 to the communication unit 2 (step S22), and ends the process.

  In addition, the said process performed in the diaper 1 repeatedly performs step S21 and step S22 until it complete | finishes after starting a process.

  The communication unit 2 determines whether or not temperature data has been received from the diaper 1 (step S31), and when temperature data has not been received (step S31; No), the process repeats step S31. When the temperature data is received (step S31; Yes), the communication unit 2 transmits the temperature data to the excretion detection server 3 (step S32) and ends the process.

  In addition, the process performed in the communication unit 2 repeatedly performs step S31 and step S32 from the start to the end of the process.

  The excretion detection server 3 determines whether or not temperature data has been received from the communication unit 2 (step S41). If temperature data has not been received (step S41; No), the process repeats step S41. When the temperature data is received (step S41; Yes), the excretion detection server 3 analyzes the temperature data (step S42) and determines whether there is excretion (step S43). When it determines with having not excreted (step S43; No), a process returns to step S41 and repeats step S41-step S43.

  When it determines with having excreted (step S43; Yes), the excretion detection server 3 determines the kind of excretion (step S44). Next, excretion information is created based on the determined excretion type (step S45). Subsequently, the excretion detection server 3 transmits the created excretion information to the information distribution terminal 4 (step S46), and ends the process.

  In addition, the said process performed in the excretion detection server 3 repeatedly performs step S41-step S46 until it complete | finishes after starting a process.

  The information distribution terminal 4 determines whether or not the excretion information is received from the excretion detection server 3 (step S51). If the excretion information is not received (step S51; No), the process repeats step S51. When excretion information is received (step S51; Yes), the information distribution terminal 4 outputs excretion information with a screen display or a voice (step S52), and ends the process.

  In addition, the said process performed in the information delivery terminal 4 repeatedly performs step S51 and step S52 until it complete | finishes after starting a process.

  Thus, in the excretion information delivery system 100 of this embodiment, since it can generate electric power in the diaper 1, facilities, such as a receiving function of a diaper main body and a transmitter installed around a diaper wearer, are unnecessary. In addition, since power is generated using urine, there is no need to attach a power source such as a battery pad when the diaper is mounted. In addition, possession of information terminal devices by caregivers such as infant guards and elderly caregivers, it is possible to know the excretion information of diaper wearers even when they are not there. Reducing the restraint time of those who do. Thereby, the stress of those who care for the diaper wearer can be reduced.

[Modification]
In the above embodiment, the data transmission unit 200 is disposed at the center of the diaper 1. However, the application of the present invention is not limited to this, and the diaper 1 is disposed anywhere as long as urine is supplied to the battery 12. May be.

  In the above embodiment, the diaper 1 includes the temperature sensor 13, but the application of the present invention is not limited thereto, and the diaper 1 does not include the temperature sensor, and only urination is performed depending on whether electricity is generated in the battery 12. May be detected and a signal may be transmitted to the communication unit 2.

  In said embodiment, although the sensor with which the diaper 1 is provided was the temperature sensor 13, application of this invention is not restricted to this, A sensor etc. which detect the component contained in a humidity sensor or excrement may be sufficient. These may be combined.
