The present disclosure relates to determination devices and detection devices.

2. Description of the Related Art Conventionally, there has been known a detection device that is attached to incontinence countermeasure clothing such as a diaper to detect excrement. For example, Patent Literature 1 and Patent Literature 2 describe devices that detect excretion or the like based on temperature changes detected by a temperature sensor attached to a diaper.

JP 2010-194277 A Japanese Patent Publication No. 2007-530154

If such a detection device is not attached to a diaper or the like in the correct orientation, it may not be possible to detect excrement normally. In other words, if the detection device is attached in the wrong direction, there is a risk that the detection accuracy will be degraded.

In this technical field, it is desired to improve the detection accuracy of excrement by a detection device.

A determination device according to one aspect of the present disclosure includes a substrate, a gas sensor that detects a target gas that is a gas to be detected that is generated from excrement, and a circulator that sucks gas and discharges the sucked gas toward the gas sensor. , a first temperature sensor, and a second temperature sensor. This determination device includes a first acquisition unit that acquires the first temperature detected by the first temperature sensor, a second acquisition unit that acquires the second temperature detected by the second temperature sensor, the first temperature and the second temperature. 2. A determination unit that determines the direction in which the detection device is attached to the incontinence countermeasure clothing worn by the living body based on the temperature, and an output unit that outputs the determination result of the determination unit. The substrate has a first side and a second side opposite the first side. A gas sensor and a first temperature sensor are provided on the first surface. A second temperature sensor is provided on the second surface.

In this determination device, the first temperature detected by the first temperature sensor provided on the first surface of the substrate and the second temperature detected by the second temperature sensor provided on the second surface of the substrate are Based on this, the orientation in which the detection device is attached to the incontinence countermeasure garment is determined. Generally, the temperature of the body surface is higher than the temperature of the outside air, and the temperature of the gas in the space formed between the incontinence countermeasure clothing and the living body is higher than the temperature of the gas outside the incontinence countermeasure clothing. Therefore, for example, when the first surface faces the incontinence countermeasure garment, the second temperature sensor is closer to the body surface than the first temperature sensor, so the second temperature is higher than the first temperature. obtain. When the circulatory system sucks gas from the space formed between the incontinence countermeasure clothing and the living body, compared with the case where the circulatory system sucks gas from the outside of the incontinence countermeasure clothing, the first Temperatures can be high. By considering these relationships, it is possible to stably determine the mounting orientation of the detection device from the first temperature and the second temperature. Therefore, the detection device can be mounted in the correct orientation without being affected by the caregiver's mounting work. As a result, it is possible to improve the detection accuracy of the excrement by the detection device.

The determination unit may determine whether the first surface faces the incontinence countermeasure garment or the living body by comparing the first temperature and the second temperature. When the first surface faces the incontinence protection garment, the second temperature sensor is closer to the body surface than the first temperature sensor. Therefore, the second temperature can be higher than the first temperature. On the other hand, when the first surface faces the living body, the first temperature sensor is closer to the body surface of the living body than the second temperature sensor. Therefore, the first temperature can be higher than the second temperature. In this way, it can be determined whether the first surface faces the incontinence garment or the living body simply by comparing the first temperature and the second temperature.

The determination unit compares the first temperature with a predetermined threshold to determine whether the circulatory system is sucking gas from the space formed between the incontinence countermeasure clothing and the living body. It may be determined whether gas is being sucked from. In general, the temperature of the gas in the space formed between the incontinence countermeasure clothing and the living body is higher than the temperature of the gas outside the incontinence countermeasure clothing. Therefore, when the circulatory system is sucking gas from the space formed between the incontinence countermeasure garment and the living body, the first temperature can be higher than the threshold. On the other hand, if the circulator is sucking gas from outside the incontinence garment, the first temperature may be lower than the threshold. Thus, it is determined whether the circulatory system is sucking gas from the space formed between the incontinence countermeasure clothing and the living body or the outside of the incontinence countermeasure clothing simply by comparing the first temperature and the threshold value. can be

The determination unit may determine the mounting orientation of the detection device using a temperature difference obtained by subtracting the first temperature from the second temperature. Since there are individual differences in body temperature, the first temperature and the second temperature may differ depending on the living body. On the other hand, by subtracting the first temperature from the second temperature, a relative magnitude relationship between the first temperature and the second temperature can be obtained. Therefore, by using the temperature difference, the influence of individual differences can be reduced. Therefore, it is possible to improve the accuracy of determining the mounting orientation of the detection device.

The determination unit determines a first rise characteristic from when the detection device is installed until the first temperature converges to a first steady temperature in a steady state, and a second steady state temperature at which the second temperature is in a steady state after the detection device is installed. The mounting orientation of the detection device may be determined based on the second rise characteristic until the temperature converges. Since there are individual differences in body temperature, the first temperature and the second temperature may differ depending on the living body. On the other hand, each of the first rising characteristic and the second rising characteristic has characteristics common to individuals. Therefore, by using the first rising characteristic and the second rising characteristic, the influence of individual differences can be reduced. Therefore, it is possible to improve the accuracy of determining the mounting orientation of the detection device.

A detection device according to another aspect of the present disclosure is a device that is attached to incontinence countermeasure clothing worn by a living body and that detects excrement using a target gas that is a detection target gas generated from excrement. This detection device includes a substrate having a first surface and a second surface opposite to the first surface, a gas sensor provided on the first surface for detecting a target gas, and a gas sensor provided on the first surface for sucking the gas. a circulator for discharging sucked gas toward a gas sensor; a first temperature sensor provided on the first surface; a second temperature sensor provided on the second surface; and a first temperature detected by the first temperature sensor. and a determination device that determines the mounting orientation of the detection device based on the second temperature detected by the second temperature sensor.

In this detection device, the first temperature detected by the first temperature sensor provided on the first surface of the substrate and the second temperature detected by the second temperature sensor provided on the second surface of the substrate are Based on this, the mounting orientation of the detection device is determined. Generally, the temperature of the body surface is higher than the temperature of the outside air, and the temperature of the gas in the space formed between the incontinence countermeasure clothing and the living body is higher than the temperature of the gas outside the incontinence countermeasure clothing. Therefore, for example, when the first surface faces the incontinence countermeasure garment, the second temperature sensor is closer to the body surface than the first temperature sensor, so the second temperature is higher than the first temperature. obtain. When the circulatory system sucks gas from the space formed between the incontinence countermeasure clothing and the living body, compared with the case where the circulatory system sucks gas from the outside of the incontinence countermeasure clothing, the first Temperatures can be high. By considering these relationships, it is possible to stably determine the mounting orientation of the detection device from the first temperature and the second temperature. Therefore, the detection device can be mounted in the correct orientation without being affected by the caregiver's mounting work. As a result, it is possible to improve the detection accuracy of the excrement by the detection device.

The detection device may further include an output device for outputting a result of determination by the determination device. In this case, a caregiver or the like can recognize the determination result. Therefore, when the detection device is not mounted in the correct orientation, a caregiver or the like can remount the detection device in the correct orientation. As a result, it is possible to improve the detection accuracy of the excrement by the detection device.

The gas sensor may be provided at a position closer to the circulator than the first temperature sensor. By providing the gas sensor near the circulator, it becomes easier for the gas discharged from the circulator to reach the gas sensor. Therefore, it is possible to improve the detection accuracy of the target gas contained in the gas discharged from the circulator.

FIG. 2 is a diagram schematically showing the configuration of the detection device shown in FIG. 1; FIG. 3 is a functional block diagram of the processing device shown in FIG. 2; FIG. 4 is a diagram showing an example of how the detection device shown in FIG. 1 is mounted. 5 is a cross-sectional view taken along line VV of FIG. 4. FIG. A detection device 10 shown in FIG. 1 is a device for detecting excrement of a living body 3 to be monitored. The detection device 10 detects excrement by the target gas. The target gas is a gas (smell) to be detected that is generated from excrement. The living body 3 is not limited to humans, and may be other animals. Excretions detected by the detection device 10 include urine, feces, and the like.

The detection device 10 is a portable device, and is configured to be detachable from the incontinence countermeasure clothing 2 worn by the living body 3 . The incontinence countermeasure garment 2 is, for example, a pants-type garment. In this embodiment, the incontinence countermeasure garment 2 is a diaper. The incontinence countermeasure clothing 2 is provided with a pocket 2b. The pocket 2b has a bag-like shape and is used to accommodate the detection device 10. As shown in FIG. The pocket 2b is made of an air-permeable forming material. Examples of forming materials include nonwoven fabrics. The pocket 2b is provided on the inner surface of the edge 2a of the incontinence countermeasure garment 2. As shown in FIG. The pocket 2b may be configured integrally with the incontinence countermeasure garment 2, or may be attached to the inner surface of the incontinence countermeasure garment 2 with a fixing member such as a double-sided tape or hook-and-loop fastener.

The detection device 10 includes a substrate 11, a circulator 12, a gas sensor 13, a temperature sensor 14 (first temperature sensor), a temperature sensor 15 (second temperature sensor), a processing device 16 (determination device), and an output A device 17 and a communication device 18 are provided.

The substrate 11 is a rectangular plate-shaped member. The substrate 11 has a surface 11a (first surface) and a surface 11b (second surface). The surface 11a faces the inner surface of the incontinence countermeasure garment 2 when the detection device 10 is attached to the incontinence countermeasure garment 2 in the correct orientation. The surface 11b is the surface opposite to the surface 11a, and faces the living body 3 when the detection device 10 is attached to the incontinence countermeasure garment 2 in the correct direction.

The circulator 12 is a device that sucks gas and discharges the sucked gas toward the gas sensor 13 . Circulator 12 operates like a syringe. A circulator 12 is provided on the surface 11a. With the detecting device 10 attached to the incontinence countermeasure garment 2 in the correct orientation, the circulator 12 sucks gas from the space V formed between the incontinence countermeasure garment 2 and the living body 3, and releases the sucked gas. It is discharged toward the gas sensor 13 . The circulator 12 includes a housing 21 , a check valve 22 and a check valve 23 .

The housing 21 has a flat, hollow box shape and defines an internal space SP. The housing 21 is composed of an elastic member that can be elastically deformed. The elastic member is, for example, a soft material that is highly safe for the living body 3 . Such materials include polyethylene terephthalate and polyethylene. The housing 21 is provided near the end portion 11c of the surface 11a.

The check valve 22 is provided at one end of the housing 21 in the direction D1. The check valve 22 is a valve for preventing gas from flowing from the internal space SP to the outside, and allows gas to pass from the outside toward the internal space SP. The check valve 23 is provided at the other end of the housing 21 in the direction D1. The check valve 23 is a valve for preventing gas from flowing into the internal space SP from the outside, and allows gas to pass from the internal space SP to the outside. The check valve 23 faces the gas sensor 13 in the direction D1. When the detection device 10 is attached to the incontinence countermeasure garment 2 in the correct direction, the check valves 22 and 23 allow gas to flow in one direction (direction D1) from the space V toward the gas sensor 13 .

The gas sensor 13 is a sensor for detecting the smell of excrement (target gas). The gas sensor 13 is provided on the surface 11a. The gas sensor 13 is arranged in parallel with the check valve 23 in the direction D<b>1 and receives the gas released from the check valve 23 . As the gas sensor 13, a semiconductor type gas sensor, an electrochemical type gas sensor, a crystal oscillator type gas sensor, or the like is used. A target gas for detecting urine as excrement is, for example, ammonia. Examples of target gases for detecting stool as excrement include hydrogen sulfide and methyl mercaptan. The gas sensor 13 outputs a measured value, which is an analog value corresponding to the concentration of the target gas, to the processing device 16 .

Temperature sensors 14 and 15 are sensors for measuring temperature. The temperature sensor 14 is provided on the surface 11a and arranged near the end portion 11d. That is, the circulator 12, the gas sensor 13, and the temperature sensor 14 are arranged in that order in the direction D1. The temperature sensor 15 is provided on the surface 11b and arranged near the end portion 11d. The temperature sensor 15 is provided, for example, at a position corresponding to the temperature sensor 14 with the substrate 11 interposed therebetween. The temperature sensors 14 and 15 output the measured temperatures to the processing device 16 as measured values.

The processing device 16 controls the detection device 10 as a whole. The processing device 16 is, for example, a controller including a processor such as a CPU (Central Processing Unit) and memories such as a RAM (Random Access Memory) and a ROM (Read Only Memory). The processing device 16 is mounted on the substrate 11 . The processing device 16 controls the operations of the gas sensor 13 and temperature sensors 14 and 15, and acquires measured values from the gas sensor 13 and temperature sensors 14 and 15 at predetermined sampling intervals. A sampling interval of measured values from the gas sensor 13 and the temperature sensors 14 and 15 is, for example, about one second.

The processing device 16 determines the mounting orientation of the detection device 10 based on the measured value (temperature T1) detected by the temperature sensor 14 and the measured value (temperature T2) detected by the temperature sensor 15 . A method of determining the mounting orientation will be described later. The processing device 16 operates the output device 17 based on the determination result of the wearing orientation. The processing device 16 converts the determination result into transmission data that can be transmitted by the communication device 18 and outputs the transmission data to the communication device 18 . The processing device 16 may include a device ID (Identifier) that can uniquely identify the detecting device 10 in the transmission data. Note that the processing device 16 may convert the measured values obtained from each sensor into transmission data and output the transmission data to the communication device 18 .

By reading and executing the program stored in the memory, each hardware operates under the control of the processor, and data is read and written in the memory. Thereby, each functional unit of the processing device 16 shown in FIG. 3 is realized. As shown in FIG. 3, the processing device 16 functionally includes an acquisition unit 61 (first acquisition unit), an acquisition unit 62 (second acquisition unit), a determination unit 63, an output unit 64, It has

The acquisition unit 61 is a functional unit that acquires the temperature T<b>1 (first temperature) detected by the temperature sensor 14 . The acquisition unit 62 is a functional unit that acquires the temperature T2 (second temperature) detected by the temperature sensor 15 . The determination unit 63 is a functional unit that determines the direction in which the detection device 10 is attached to the incontinence countermeasure clothing 2 based on the temperature T1 and the temperature T2. The orientation in which the detection device 10 is attached to the incontinence countermeasure clothing 2 is simply referred to as the "wearing orientation of the detection device 10". The output unit 64 is a functional unit that outputs the result of determination by the determination unit 63 .

The output device 17 is a device that outputs various information. The output device 17 is arranged, for example, in a manner capable of transmitting information to the outside of the incontinence countermeasure clothing 2 while the detection device 10 is attached to the incontinence countermeasure clothing 2 . Examples of the output device 17 include an LED (Light Emitting Diode), a display, a speaker, and a vibrator. The output device 17 outputs the determination result by the processing device 16 . For example, when the determination result indicates incorrect attachment, the output device 17 notifies the caregiver or the like of incorrect attachment of the detection device 10 by means of light, vibration, sound, display screen, or the like.

The communication device 18 is a device for transmitting and receiving data to and from an external information processing device (not shown). In this embodiment, the communication device 18 is a wireless communication module that wirelessly transmits and receives data. The communication device 18 transmits data received from the processing device 16 to an external information processing device, and outputs data received from the external information processing device to the processing device 16 .

The detection device 10 further includes a case (housing) 19 . The case 19 has a flat, hollow box shape and accommodates the substrate 11, circulator 12, gas sensor 13, temperature sensor 14, temperature sensor 15, processing device 16, output device 17, and communication device 18. . Like the housing 21, the case 19 is made of an elastic member that can be elastically deformed. The elastic member is, for example, a soft material that is highly safe for the living body 3 . Such materials include polyethylene terephthalate and polyethylene. The case 19 is provided with a vent hole 19a and a vent hole 19b. The vent hole 19 a is provided in the side wall of the case 19 that faces the check valve 22 of the circulator 12 . The vent hole 19b is provided in the side wall of the case 19 that faces the check valve 23 of the circulator 12 .

Next, the operation of the detection device 10 will be described with further reference to FIGS. 6(a) and 6(b). FIG. 6(a) is a cross-sectional view showing the state of the circulatory system shown in FIG. 1 when the living body inhales. FIG. 6(b) is a sectional view showing the state of the circulatory system shown in FIG. 1 when the living body exhales. As shown in FIGS. 4 and 5 , the detection device 10 is attached to the incontinence clothing 2 so as to be positioned between the incontinence clothing 2 and the living body 3 . In this example, the detection device 10 is attached to the inner surface of the incontinence countermeasure garment 2 on the abdomen side. That is, the detection device 10 is provided between the incontinence countermeasure garment 2 and the abdomen 3a of the living body 3. As shown in FIG. For example, the detection device 10 is accommodated in a pocket provided on the inner surface of the incontinence countermeasure clothing 2 .

Specifically, the end portion 11 d of the substrate 11 is arranged along the edge portion 2 a of the incontinence countermeasure garment 2 . Since the edge 2a has stretchability, the detection device 10 is pressed toward the abdomen 3a. At this time, the surface 11a faces the inner surface of the abdomen side of the incontinence countermeasure garment 2, the surface 11b faces the living body 3 (abdomen 3a), the end portion 11d is positioned on the upper body side of the living body 3, and the end portion 11c faces the living body 3. Located on the lower body side. A space V is formed between the incontinence countermeasure clothing 2 and the living body 3 .

Since the position of the abdomen 3a changes when the living body 3 breathes, the volume of the internal space SP of the housing 21 changes according to the breathing motion. Specifically, as shown in FIG. 6(a), when the living body 3 breathes, the abdomen 3a expands, so the circulatory organ 12 is sandwiched between the incontinence countermeasure garment 2 and the abdomen 3a (substrate 11). A force is applied to the housing 21 . Therefore, the housing 21 is crushed, and the volume of the internal space SP (internal space capacity) of the housing 21 is reduced. As a result, the gas inside the internal space SP is discharged to the outside of the housing 21 . At this time, the gas in the internal space SP is discharged toward the gas sensor 13 through the check valve 23 and is led out of the case 19 through the ventilation hole 19b.

On the other hand, as shown in FIG. 6(b), when the living body 3 exhales, the abdomen 3a contracts, so the force applied to the housing 21 by the incontinence countermeasure clothing 2 and the abdomen 3a (substrate 11) decreases. . Therefore, the shape of the housing 21 is restored by the restoring force of the housing 21, and the volume of the internal space SP increases. As a result, the gas is introduced from the space V into the case 19 through the vent hole 19 a and sucked into the internal space SP through the check valve 22 . In this way, the abdomen 3a is repeatedly inflated and deflated by breathing of the living body 3, and the volume of the internal space SP is changed. Gas discharge from the SP to the gas sensor 13 is repeated.

When the living body 3 excretes (incontinence), the space V is filled with the target gas released from the excrement. By repeating the above operation of the circulator 12 in response to respiration, the target gas (smell) in the space V is agitated and discharged toward the gas sensor 13 . As a result, the target gas is delivered to the vicinity of the gas sensor 13 and detected by the gas sensor 13 . Thus, when the detection device 10 is attached to the incontinence countermeasure garment 2 in the correct direction, the surface 11a faces the inner surface of the incontinence countermeasure garment 2, and the circulator 12 discharges the gas in the space V toward the gas sensor 13. be done.

Next, a method for determining the mounting orientation of the detection device will be described with reference to FIGS. 7 to 14. FIG. FIG. 7 is a diagram showing a state in which the detection device shown in FIG. 1 is mounted upside down. FIG. 8 is a diagram showing a state in which the detection device shown in FIG. 1 is mounted upside down. FIG. 9 is a diagram showing a state in which the detection device shown in FIG. 1 is mounted upside down and inside out. FIG. 10 is a flow chart showing a series of processes of a method for determining the mounting orientation of the detection device. FIG. 11 is a diagram showing temporal changes in measured values of the temperature sensor when the detection device shown in FIG. 1 is mounted in the correct orientation. FIG. 12 is a diagram showing temporal changes in measured values of the temperature sensor when the detection device shown in FIG. 1 is mounted upside down. FIG. 13 is a diagram showing temporal changes in measured values of the temperature sensor when the detection device shown in FIG. 1 is mounted upside down. FIG. 14 is a diagram showing temporal changes in measured values of the temperature sensor when the detection device shown in FIG. 1 is mounted upside down and inside out. The horizontal axis in FIGS. 11 to 14 indicates the time that has elapsed since the detection device 10 was attached to the incontinence countermeasure garment 2 . The vertical axes in FIGS. 11 to 14 indicate temperature.

The detection device 10 of this embodiment does not have a mechanism for attaching to the incontinence countermeasure clothing 2, such as a belt. Therefore, the detection device 10 may not be mounted in the correct orientation. For example, as shown in FIG. 7, the detection device 10 may be mounted upside down. When the detecting device 10 is mounted upside down, the surface 11a faces the inner surface of the incontinence countermeasure garment 2 and the surface 11b faces the living body 3, but the end portion 11c is positioned on the upper body side of the living body 3, and the end portion 11c faces the upper body side of the living body 3. The portion 11d is located on the lower body side of the living body 3. As shown in FIG. In this case, the circulator 12 sucks gas from the outside of the incontinence countermeasure garment 2 and discharges the gas toward the gas sensor 13 . As a result, the gas in the space V is less likely to be supplied to the gas sensor 13, which may reduce the detection accuracy of excreta.

As shown in FIG. 8, the detection device 10 may be worn upside down. When the detection device 10 is mounted upside down, the end portion 11c is located on the lower body side of the living body 3 and the end portion 11d is located on the upper body side of the living body 3, but the surface 11a faces the living body 3, The surface 11b faces the inner surface of the incontinence countermeasure garment 2. - 特許庁In this case, the circulator 12 sucks gas from the space V and discharges the gas toward the gas sensor 13 . However, there is a possibility that the measured value of the gas sensor 13 may vary depending on whether the gas sensor 13 faces the inner surface of the incontinence countermeasure garment 2 or faces the living body 3 . For this reason, there is a possibility that the detection accuracy of excrement may be lowered. In addition, the design of the case 19 may be asymmetrical between the front and back in consideration of the feeling of wearing the detection device 10 and the like. In such a case, if the detection device 10 is worn upside down, there is a possibility that a sufficient feeling of wearing may not be obtained.

As shown in FIG. 9, the detection device 10 may be mounted upside down and upside down. When the detection device 10 is mounted upside down and inside out, the surface 11a faces the living body 3, the surface 11b faces the inner surface of the incontinence countermeasure garment 2, and the end portion 11c is positioned on the upper body side of the living body 3. The portion 11d is located on the lower body side of the living body 3. As shown in FIG. In this case, the circulator 12 sucks gas from the outside of the incontinence countermeasure garment 2 and discharges the gas toward the gas sensor 13, as in the case where the detection device 10 is mounted upside down. As a result, the gas in the space V is less likely to be supplied to the gas sensor 13, which may reduce the detection accuracy of excrement.

Therefore, the processing device 16 determines the mounting orientation of the detection device by performing a series of processes shown in FIG. This series of processes is started, for example, at predetermined sampling intervals. First, the acquisition unit 61 acquires the temperature T1 from the temperature sensor 14 (step S1), and the acquisition unit 62 acquires the temperature T2 from the temperature sensor 15 (step S2). Step S1 and step S2 may be performed simultaneously, or one of them may be performed first.

Subsequently, the determination unit 63 determines the mounting orientation of the detection device 10 based on the temperature T1 and the temperature T2 (step S3), and outputs the determination result of the mounting orientation to the output unit 64 . When the sensing device 10 is mounted in the correct orientation, temperature T1 and temperature T2 change over time as shown in FIG. When the detection device 10 is mounted in the correct orientation, the temperature sensor 14 is farther from the body surface of the living body 3 than the temperature sensor 15 is. Therefore, temperature T1 is less affected by body temperature than temperature T2. On the other hand, the gas discharged from the space V toward the gas sensor 13 by the circulator 12 reaches the temperature sensor 14 . Since the gas temperature in the space V is higher than the gas temperature outside the incontinence countermeasure garment 2, the temperature T1 is expected to reach a certain temperature.

Therefore, the steady-state temperature T _T1 (first steady-state temperature) of temperature T1 and the steady-state temperature T _T2 (second steady-state temperature) of temperature T2 are both higher than the threshold temperature T _th (threshold), and the steady-state temperature T _T2 is Temperature TT higher than _T1 . The steady temperature _TT1 is the steady state temperature T1, and is the temperature at which the amount of change per unit time of the temperature T1 is lower than a predetermined value. The steady temperature _TT2 is the steady state temperature T2, and is the temperature at which the amount of change per unit time of the temperature T2 is lower than a predetermined value. That is, when the condition of T _T2 >T _T1 >T _th is satisfied, the determination unit 63 determines that the detection device 10 is mounted in the correct orientation.

When the detection device 10 is mounted upside down, the temperature T1 and the temperature T2 change over time as shown in FIG. The temperature T2 when the detection device 10 is mounted upside down is substantially the same as the temperature T2 when the detection device 10 is mounted in the correct direction. However, the gas discharged from the outside of the incontinence countermeasure garment 2 toward the gas sensor 13 by the circulator 12 reaches the temperature sensor 14 . Since the gas temperature outside the incontinence countermeasure clothing 2 is lower than the gas temperature in the space V, the temperature T1 when the detection device 10 is mounted upside down is lower than the temperature T1 when the detection device 10 is mounted in the correct direction. also lower. Therefore, the steady-state temperature _TT2 is higher than the threshold temperature _Tth , and the steady-state temperature _TT1 is lower than the threshold temperature _Tth . That is, when the condition of T _T2 >T _th >T _T1 is satisfied, the determination unit 63 determines that the detection device 10 is mounted upside down.

When the detection device 10 is mounted upside down, the temperature T1 and the temperature T2 change over time as shown in FIG. When the detection device 10 is mounted upside down, the temperature sensor 14 is closer to the body surface of the living body 3 than the temperature sensor 15, and the gas discharged from the space V toward the gas sensor 13 by the circulator 12 is detected by the temperature sensor. reach 14. The temperature T1 is more influenced by the body temperature of the living body 3 than by the temperature of the gas discharged by the circulator 12 . On the other hand, temperature T2 is less affected by body temperature than temperature T1. Therefore, the steady-state temperature _TT1 and the steady-state temperature _TT2 are both higher than the threshold temperature _Tth , and the steady-state temperature _TT1 is higher than the steady-state temperature _TT2 . That is, when the condition of T _T1 >T _T2 >T _th is satisfied, the determination unit 63 determines that the detection device 10 is mounted upside down.

When the detection device 10 is mounted upside down and upside down, the temperature T1 and the temperature T2 change over time as shown in FIG. When the detection device 10 is mounted upside down and inside out, the temperature sensor 14 is closer to the body surface of the living body 3 than the temperature sensor 15, but the circulator 12 directs the temperature from the outside of the incontinence countermeasure clothing 2 toward the gas sensor 13. The exhaled gas reaches the temperature sensor 14 . Therefore, although the temperature T1 is affected by the body temperature of the living body 3, it does not reach the threshold temperature _Tth . Temperature T2 is affected by the gas discharged by circulator 12 . Therefore, the steady-state temperature _TT1 and the steady-state temperature _TT2 are both lower than the threshold temperature _Tth , and the steady-state temperature _TT1 is higher than the steady-state temperature _TT2 . That is, when the condition of T _th >T _T1 >T _T2 is satisfied, the determination unit 63 determines that the detection device 10 is mounted upside down and upside down.

Subsequently, the output unit 64 outputs the determination result to the output device 17 and the communication device 18 (step S4). When the output device 17 receives the determination result from the processing device 16, the output device 17 outputs the determination result to a caregiver or the like. For example, when the determination result indicates erroneous attachment (upside down, upside down, or upside down and upside down), the output device 17 detects erroneous attachment of the detection device 10 by light, vibration, sound, display screen, etc. etc. Further, when the communication device 18 receives the determination result from the processing device 16, the communication device 18 transmits the determination result to an external information processing device and outputs it to a display or the like of the information processing device.

A series of processes of the method for determining the mounting orientation of the detection device 10 is thus completed.

In the processing apparatus 16 and the detection apparatus 10 described above, the temperature T1 detected by the temperature sensor 14 provided on the surface 11a of the substrate 11 and the temperature T2 detected by the temperature sensor 15 provided on the surface 11b of the substrate 11 , and the orientation in which the detection device 10 is attached to the incontinence countermeasure clothing 2 is determined. In general, the temperature of the body surface of the living body 3 is higher than the temperature of the outside air, and the temperature of the gas in the space V formed between the incontinence countermeasure clothing 2 and the living body 3 is higher than the temperature of the gas outside the incontinence countermeasure clothing 2. is also expensive. Therefore, for example, when the surface 11a faces the incontinence countermeasure garment 2, the temperature sensor 15 is closer to the body surface of the living body 3 than the temperature sensor 14, so the temperature T2 can be higher than the temperature T1. When the circulator 12 sucks gas from the space V, the temperatures T1 and T2 can be higher than when the circulator 12 sucks gas from the outside of the incontinence countermeasure garment 2 .

By considering these relationships, it is possible to stably determine the mounting orientation of the detection device 10 from the temperature T1 and the temperature T2. In other words, the mounting orientation of the detection device 10 is determined under stable conditions from a combination of the gas affected by the body surface temperature, the gas affected by the temperature inside the incontinence countermeasure garment 2, and the gas affected by the temperature of the outside air. be able to. Thus, it is possible to determine the mounting orientation of the detection device 10 with very little power consumption and a simple structure. Therefore, the detection device 10 can be mounted in the correct orientation without being affected by the caregiver's mounting work. As a result, the gas sensor 13 of the detection device 10 can be prevented from being blocked by the skin and clothing, and the gas sucked from the space V can reach the gas sensor. As a result, when the target gas is contained in the gas in the space V, the target gas can be easily detected, so that the detection accuracy of excrement by the detection device 10 can be improved.

Since the detection device 10 includes the output device 17, a caregiver or the like can recognize the determination result. Therefore, when the detection device 10 is not mounted in the correct orientation, a caregiver or the like can remount the detection device 10 in the correct orientation. As a result, it becomes possible to improve the detection accuracy of the excrement by the detecting device 10 .

The gas sensor 13 is provided at a position closer to the circulator 12 than the temperature sensor 14 is. By providing the gas sensor 13 near the circulator 12 , it becomes easier for the gas discharged from the circulator 12 to reach the gas sensor 13 . Therefore, it is possible to improve the detection accuracy of the target gas contained in the gas discharged from the circulator 12 .

Since the housing 21 is made of an elastic member that can be elastically deformed, when a force is applied to the housing 21 from the outside, the housing 21 is crushed and the volume of the internal space SP of the housing 21 is reduced. As a result, the gas inside the internal space SP is discharged toward the gas sensor 13 via the check valve 23 . Further, by removing the force applied to the housing 21, the shape of the housing 21 is restored to its original shape, and the volume of the internal space SP of the housing 21 increases. As a result, gas is sucked from the space V into the internal space SP via the check valve 22 . By repeating this operation, the suction of gas from the space V into the internal space SP and the discharge of gas from the internal space SP to the gas sensor 13 are repeated.

Specifically, the abdomen 3a is inflated by breathing of the living body 3, and the action of returning to the original state is repeated. The force applied to 21 repeats increase and decrease. As a result, suction and discharge by the circulator 12 can be performed using breathing motion. In the detecting device 10 , by using the action of respiration necessary for life activities of the living body 3 as an energy source, suction and discharge are performed by the circulator 12 without using an electrically driven suction pump and fan. Thus, the target gas generated from excrement is sent to the gas sensor 13 by suction and discharge by the circulator 12 which does not require electric power.

When excreted, the target gas is generated from the excrement, and the target gas diffuses due to the operation of the circulator 12 and reaches the gas sensor 13 . Therefore, even if the gas sensor 13 is provided at a position physically separated from excrement, the delay time from the time of excretion until the gas sensor 13 detects the target gas can be shortened. In addition, when the circulator 12 is not provided, the target gas generated from the excrement naturally diffuses, so that the target gas diffuses and reaches the gas sensor 13 in a state where the concentration of the target gas is not uniform. Therefore, in a transient state in which detection by the gas sensor 13 begins, the measured value of the gas sensor 13 may become unstable. However, by sending the gas in the space V to the gas sensor 13 while stirring it with the circulator 12, it is possible to shorten the time during which the measurement value of the gas sensor 13 becomes unstable, thereby improving the stability of detection. It becomes possible. As a result, power consumption can be reduced while improving detection accuracy.

Note that the determination device and the detection device according to the present disclosure are not limited to the above embodiments.

In the above embodiment, the incontinence countermeasure clothing 2 includes the pocket 2b for accommodating the detection device 10, but the pocket 2b may be omitted. In this case, the detection device 10 may be used by being directly sandwiched between the edges 2a of the incontinence protection garment 2. FIG.

In the above-described embodiment, the detection device 10 is attached to a portion of the inner surface of the incontinence countermeasure garment 2 facing the abdomen 3a, but the attachment position of the detection device 10 is not limited to this. The detection device 10 may be attached to a portion of the inner surface of the incontinence countermeasure garment 2 that faces the side of the living body 3 . The detection device 10 may be attached to a portion of the inner surface of the incontinence countermeasure garment 2 facing the back 3b. When the detection device 10 is attached to the abdomen side of the incontinence countermeasure clothing 2, the case 19 may be configured so as not to cool the abdomen 3a of the living body 3. For example, case 19 may be made of a material with low thermal conductivity.

The measured value of the gas sensor 13 may be corrected based on the temperatures measured by the temperature sensors 14 and 15 . This makes it possible to improve detection accuracy.

The circulator 12, the gas sensor 13, and the temperature sensor 14 may be arranged in the order of the circulator 12, the temperature sensor 14, and the gas sensor 13 in the direction D1.

The detection device 10 may further include sensors other than the gas sensor 13 and temperature sensors 14 and 15 . For example, the detection device 10 may further include a sensor for detecting activity status of the living body 3 . Sensors for detecting the activity status of the living body 3 include, for example, an acceleration sensor, an angular velocity sensor, a vibration sensor, a shock sensor, and a geomagnetic sensor. The detection device 10 may further include a sensor for detecting whether or not the detection device 10 is attached to the incontinence countermeasure garment 2 . Such sensors include, for example, contact sensors, optical sensors, push switches, and pressure sensors.

The housing 21 is not limited to the breathing action of the living body 3, and may be deformable according to the periodic activities of the living body 3 (for example, actions essential for life activities). Activities other than breathing motion include, for example, pulse and the like. The housing 21 is provided so as to deform according to the activity of the living body 3 performed periodically. As a result, it is possible to use the cyclical activity of the living body 3 to perform suction and discharge by the circulator 12 .

The circulatory system 12 does not have to be configured to utilize the activity of the living body 3 that is performed periodically. For example, an electrically driven suction pump and fan may be used as the circulator 12 .

The determination unit 63 may determine whether the surface 11a faces the incontinence countermeasure garment 2 or faces the living body 3 by comparing the steady temperature _TT1 and the steady temperature _TT2 . When the surface 11 a faces the incontinence countermeasure garment 2 , the temperature sensor 15 is closer to the body surface of the living body 3 than the temperature sensor 14 . Therefore, the steady-state temperature _TT2 can be higher than the steady-state temperature _TT1 . On the other hand, when the surface 11 a faces the living body 3 , the temperature sensor 14 is closer to the body surface of the living body 3 than the temperature sensor 15 . Therefore, the steady-state temperature _TT1 can be higher than the steady-state temperature _TT2 . Thus, it can be determined whether the surface 11a faces the incontinence countermeasure garment 2 or the living body 3 simply by comparing the steady temperature _TT1 and the steady temperature _TT2 . The determining unit 63 uses the temperature T1 and the temperature _T2 at a certain time instead of the steady temperature T _T1 and the steady temperature T T2 to determine whether the surface 11a faces the incontinence countermeasure clothing 2 or the living body 3. You can judge.

The determination unit 63 compares the steady temperature T _T1 with the threshold temperature T _th to determine whether the circulator 12 is sucking gas from the space V or from the outside of the incontinence countermeasure clothing 2 . You can judge. Generally, the gas temperature in the space V is higher than the gas temperature outside the incontinence garment 2 . Therefore, when the circulator 12 is sucking gas from the space V, the steady-state temperature _TT1 can be higher than the threshold temperature _Tth . On the other hand, when the circulator 12 is sucking gas from the outside of the incontinence countermeasure garment 2, the steady-state temperature _TT1 can be lower than the threshold temperature _Tth . Thus, it can be determined whether the circulator 12 is sucking gas from the space V or the outside of the incontinence countermeasure clothing 2 simply by comparing the steady temperature T _T1 and the threshold temperature T _th . By comparing the steady state temperature _TT2 to the threshold temperature _Tth instead of or in addition to the steady state temperature _TT1 , the circulator 12 is drawing gas from the space V or is incontinent _. It may be determined whether gas is being sucked from the outside of the countermeasure clothing 2 . The determination unit 63 uses the temperature T1 and the temperature T2 at a certain time instead of the steady temperature T _T1 and the steady temperature T _T2 to determine whether the circulator 12 is sucking gas from the space V or whether the incontinence countermeasure clothing 2 is in use. It may be determined whether gas is being sucked from the outside.

In the above embodiment, the determining unit 63 determines the mounting orientation of the detecting device 10 using the magnitude relationship between the steady temperature T _T1 , the steady temperature T _T2 , and the threshold temperature T _th . The orientation determination method is not limited to this. For example, instead of the steady temperature _TT1 and the steady temperature _TT2 , the temperature T1 and the temperature T2 at a certain time may be used to determine the mounting orientation of the detection device 10 . Although a common threshold temperature _Tth is set for temperature T1 and temperature T2, a threshold temperature may be set for each of temperature T1 and temperature T2.

The determination unit 63 may determine the mounting orientation of the detection device 10 using the temperature difference ΔT. The temperature difference ΔT is a value obtained by subtracting the steady temperature _TT1 from the steady temperature _TT2 . The temperature difference _ΔT is a positive value when the steady-state temperature _TT2 is greater than the steady-state temperature TT1, and the temperature difference ΔT is a negative value when the steady-state temperature _TT2 is less than the steady-state temperature _TT1 . be. A temperature difference ΔT _ref , which is the temperature difference ΔT when the detection device 10 is mounted in the correct orientation, is measured in advance and set in the processing device 16 .

As described above, the temperature T2 (steady temperature T _T2 ) when the detection device 10 is mounted upside down is substantially the same as the temperature T2 (steady temperature T _T2 ) when the detection device 10 is mounted in the correct direction. However, the temperature T1 (steady temperature T _T1 ) when the detection device 10 is mounted upside down is lower than the temperature T1 (steady temperature T _T1 ) when the detection device 10 is mounted in the correct direction. Therefore, when the temperature difference ΔT is greater than the temperature difference ΔT _ref , the determination unit 63 may determine that the detection device 10 is mounted upside down. As described above, when the detection device 10 is mounted upside down and inside out, the steady temperature _TT1 is higher than the steady temperature _TT2 , but the steady temperature _TT1 and the steady temperature _TT2 are close to each other. is. Therefore, when the absolute value of the temperature difference ΔT is smaller than the temperature difference ΔT _ref , the determination unit 63 may determine that the detection device 10 is mounted upside down and upside down. When the detection device 10 is mounted upside down, the steady-state temperature _TT1 is higher than the steady-state temperature _TT2 , but the absolute value of the temperature difference ΔT is approximately the same as when the detection device 10 is mounted in the correct direction. be. Therefore, when the temperature difference ΔT is a negative value and the absolute value of the temperature difference ΔT is approximately the same as the temperature difference _ΔTref , the determination unit 63 determines that the detection device 10 is mounted upside down. good too.

Also in this modified example, the same effects as those of the detection device 10 and the processing device 16 according to the above-described embodiment are achieved. Since there are individual differences in body temperature (body surface temperature), the temperature T1 and the temperature T2 may differ depending on the living body 3 . On the other hand, by subtracting the steady temperature _TT1 from the steady temperature _TT2 , a relative magnitude relationship between the steady temperature _TT1 and the steady temperature _TT2 can be obtained. Therefore, by using the temperature difference ΔT, the influence of individual differences can be reduced. Therefore, it is possible to improve the accuracy of determining the mounting orientation of the detection device 10 . The temperature difference ΔT may be obtained by subtracting the temperature T1 from the temperature _T2 using the temperature T1 and the temperature T2 at a certain time instead of the steady temperature TT1 _and the steady temperature TT2.

The determination unit 63 may determine the mounting orientation of the detection device 10 based on the rising characteristic (first rising characteristic) of the temperature T1 and the rising characteristic (second rising characteristic) of the temperature T2. The rising characteristic of the temperature T1 is the characteristic from when the detecting device 10 is worn on the incontinence countermeasure garment 2 until the temperature T1 converges to the steady temperature _TT1 . The rising characteristic of the temperature T2 is the characteristic from when the detecting device 10 is attached to the incontinence countermeasure garment 2 until the temperature T2 converges to the steady temperature _TT2 . Note that the rise of the temperature T1 refers to the time from when the temperature T1 begins to change significantly to when the temperature T1 begins to converge to the steady temperature _TT1 . Here, the rise of the temperature T1 refers to the temperature interval from 10% to 90% of the change range of the temperature T1. Similarly, the rise of the temperature T2 refers to the time from when the temperature T2 begins to change significantly to when the temperature T2 begins to converge to the steady temperature _TT2 . Here, the rise of the temperature T2 refers to the temperature interval from 10% to 90% of the change range of the temperature T2. Rise time means the time required for rise.

When the mounting direction of the detection device 10 is correct, both the temperature T1 and the temperature T2 rise sharply, and the temperature T2 starts rising earlier than the temperature T1. Therefore, the determining unit 63 determines that both the rise time of the temperature T1 and the rise time of the temperature T2 are shorter than the predetermined set time, and that the rise start time _t2 of the temperature T2 is equal to the rise start time _t1 of the temperature T1. , it may be determined that the detection device 10 is mounted in the correct orientation. The set time is a boundary value between the steep rise time and the gentle rise time, and is preset in the processing device 16 . When the detection device 10 is mounted upside down, the temperature T2 rises sharply, but the temperature T1 rises gently. Therefore, when the rise time of the temperature T1 is longer than the set time and the rise time of the temperature T2 is shorter than the set time, the determination unit 63 determines that the detection device 10 is mounted upside down. may

When the detecting device 10 is mounted upside down, both the temperature T1 and the temperature T2 rise sharply, but the temperature T1 begins to rise earlier than the temperature T2. For this reason, the determining unit 63 determines that the temperature T1 rise time and the temperature T2 rise time are both shorter than the set time and the rise start time _t1 is shorter than the rise start time _t2 . It may be determined that 10 is worn upside down. When the detection device 10 is mounted upside down and inside out, both the temperature T1 and the temperature T2 rise gently. Therefore, when both the rise time of the temperature T1 and the rise time of the temperature T2 are longer than the set time, the determination unit 63 determines that the detection device 10 is mounted upside down and upside down. good.

Also in this modified example, the same effects as those of the detection device 10 and the processing device 16 according to the above-described embodiment are achieved. As described above, there are individual differences in body temperature (body surface temperature), so the temperature T1 and the temperature T2 may differ depending on the living body 3 . On the other hand, the rise characteristics of the temperature T1 and the rise characteristics of the temperature T2 have characteristics common to each individual. Therefore, by using the rise characteristics of the temperature T1 and the rise characteristics of the temperature T2, the influence of individual differences can be reduced. Therefore, it is possible to improve the accuracy of determining the mounting orientation of the detection device 10 .

The processing device 16 (determination unit 63) determines the determination conditions defined by the steady-state temperature T _T1 , the steady-state temperature T _T2 , and the threshold temperature T _th , the determination conditions defined by the temperature difference ΔT, and the temperature T1 and the temperature T2. The mounting orientation of the detection device 10 may be determined by combining some of the determination conditions defined by the rise characteristics.

As shown in FIG. 15 , instead of the processing device 16 , the processing device 32 of the information processing device 30 may determine the mounting orientation of the detection device 10 . The information processing device 30 is a computer such as a PC (Personal Computer) and includes a communication device 31 , a processing device 32 and an output device 33 . The communication device 31 is a device for transmitting and receiving data to and from the detection device 10 . In this modification, the communication device 31 is a wireless communication module that wirelessly transmits and receives data. The communication device 31 transmits data received from the processing device 32 to the detection device 10 (communication device 18 ), and outputs data received from the detection device 10 (communication device 18 ) to the processing device 32 . The processing device 32 is, for example, a controller including a processor such as a CPU and memories such as RAM and ROM. The processing device 32 determines the orientation of the detection device 10 in the same manner as the processing device 16 of the above embodiment. The processing device 32 operates the output device 33 based on the determination result of the wearing orientation. The output device 33 outputs the determination result by the processing device 32 . For example, when the determination result indicates incorrect attachment, the output device 33 notifies the caregiver or the like of the incorrect attachment of the detection device 10 by means of light, vibration, sound, display screen, or the like. Examples of output devices 33 include LEDs, displays, speakers, and vibrators. In this configuration, the processing device 16 converts the measured values obtained from each sensor into transmission data and outputs the transmission data to the communication device 18 .
