Description

[Technical field]

[0001] The present invention relates to undergarments for defecation and urination and a method for treating defecation and urination. [Background technology]

[0002] Most patients and elderly people in nursing hospitals are physically disabled, and therefore, for example, in many cases, a family member or caregiver takes care of defecation and urination while the patient is lying in bed. Specifically, when the patient defecates or urinates, the family member or caregiver removes the disposable diaper from the patient and puts a new diaper on the patient. This diaper changing process is carried out several times a day. During the day, when it is difficult for the family member to care for the patient, the caregiver changes the patient's diaper, but due to a shortage of caregivers, it may not be possible to change the patient's diaper in a timely manner. This may result in poor hygiene for the patient. Also, since there are separate diapers for defecation and urination, a considerable number of diapers are consumed each day. There is a risk of environmental pollution due to the large number of diapers being discarded. Summary of the Invention [Problem to be solved by the invention]

[0003] An object of the present invention is to provide an undergarment (diaper) for defecation and urination which is hygienic and capable of treating defecation and urination multiple times. [Means for solving the problem]

[0004] The undergarment for defecation and urination according to the present invention comprises an undergarment member having an internal space, a space separating member connected to the undergarment member in the internal space and separating the internal space into a first space and a second space, and an expansion part arranged in the second space, wherein the user's buttocks or the buttocks and thighs are accommodated in the first space, and when the expansion part expands in the second space, the user's buttocks or the buttocks and thighs are raised to form a defecation and urination space in the first space that can receive defecation and urination.

[0005] Another undergarment for defecation and urination according to the present invention includes an undergarment member having an internal space, an expansion portion arranged inside the undergarment member, and an optical sensor located inside the undergarment member, and when the expansion portion expands, the user's buttocks or the buttocks and thighs rise to form a space capable of receiving defecation and urination, and the optical sensor detects light reflected by the received defecation and urination or contaminated water, or light that has passed through the received defecation and urination or contaminated water, and it is determined whether the user has discharged defecation or urination based on the detection result.

[0006] Yet another undergarment for defecation and urination according to the present invention comprises a first sub-undergarment in which a user's body is accommodated, a second sub-undergarment connected to the first sub-undergarment and having an inner space, and an expansion section contained within the second sub-undergarment, wherein the expansion section expands within the second sub-undergarment to raise the user's buttocks or the buttocks and thighs, thereby forming a defecation and urination space within the first sub-undergarment that can accommodate defecation and urination. Effect of the Invention

[0007] The undergarment (diaper) for defecation and urination according to the present invention can process defecation and urination multiple times and can be reused after washing, thereby reducing environmental pollution. In addition, the undergarment for defecation and urination lifts the buttocks to form a space for receiving defecation and urination, thereby minimizing contact of the defecation and urination received in the space with the skin of the user.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0009] As used herein, singular expressions include plural expressions unless the context clearly indicates otherwise. In this specification, terms such as "comprise" or "include" should not be interpreted as including all of the components or steps described in the specification, and should be interpreted as including some components or steps not included, or including additional components or steps. In addition, terms such as "... unit" and "module" described in the specification mean a unit that processes at least one function or operation, which can be implemented in hardware or software, or a combination of hardware and software. The present invention relates to diapers for the elderly or patients (users), particularly diapers for nursing hospitals, which can process bowel movements and urination multiple times, thereby solving the trouble of frequent changing and easily carrying out bowel movements and urination.

[0010] According to one embodiment, the diaper of the present invention creates a space for receiving the defecation and urination of a user when detecting the defecation and urination of the user, immediately processes the defecation and urination received in the space, and cleans the defecation attached to the user's buttocks. Such a diaper can be reused after washing. In particular, the space is formed to minimize the contact of the received defecation and urination with the user's skin, and is therefore hygienic. In nursing hospitals, many patients and elderly people are physically handicapped, so they defecate and urinate while lying on their beds, and their families and caregivers change disposable diapers that cause environmental pollution multiple times a day. In addition, since there are separate diapers for defecation and urination, they must be changed separately. In addition, due to a shortage of caregivers, the diapers of patients are not changed smoothly, and therefore the hygienic condition of the patients may be poor. In order to solve such problems, the present invention provides a diaper that is hygienic and can process defecation and urination multiple times.

[0011] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Various embodiments of the present invention will now be described in detail with reference to the accompanying drawings, in which for the sake of convenience, it is assumed that a user of the diaper is a patient.

[0012] FIG. 1 is a view illustrating a patient lying on a bed, and FIG. 2 is a view illustrating a diaper according to an embodiment of the present invention. FIGS. 3 and 4 are views illustrating a process of creating a space for receiving defecation and urination using a diaper according to an embodiment of the present invention, and FIG. 5 is a view illustrating a cleaning structure according to an embodiment of the present invention. The diaper according to this embodiment is an undergarment worn by a patient lying on a bed as shown in FIG. 1, for example, and can treat defecation and urination multiple times. Here, the diaper can be used without restrictions such as age and gender, and can be named as an undergarment for defecation and urination from the viewpoint of treating defecation and urination as an undergarment. In other words, the diaper is not limited to a diaper for the elderly, a patient, or a baby, but includes all undergarments that can treat defecation and urination.

[0013] Referring to FIG. 2, the diaper of this embodiment includes a front surface 200a, a rear surface 200b, and a connecting surface 200c (bottom) that connects the front surface 200a and the rear surface 200b. The diaper may be worn like pants, or may be attached like a baby diaper. Although not shown in FIG. 2, for example, a hook-and-loop fastener or zipper (lock) that can be opened and closed may be formed on the left or right side of the front surface 200a. Of course, the lock may be formed on the rear surface 200b, but since the rear surface 200a includes various components as described below, it is efficient to provide the lock on the front surface 200a. The rear surface 200b includes a buttocks portion 210, a first thigh portion 212, and a second thigh portion 214, and the buttocks portion 200b may have buttocks support portions 220a and 220b (support members) that support the left and right buttocks. The buttocks support parts 220a and 220b perform the function of supporting the left and right buttocks and lifting the buttocks during defecation and urination, and may be, for example, pads.

[0014] According to an embodiment, the hip supports 220a and 220b may each have the structure shown in FIG. 3. Specifically, the hip support 220 may be formed on the inner surface 200b-1 between the inner surface 200b-1 and the outer surface 200b-2 (inner space) of the rear surface 200b. Here, the inner surface 200b-1 may be a portion that contacts the patient's hips, and the outer surface 200b-2 may be a portion that contacts the bed. In addition, the air injection tube 300 may be connected to the inner surface 200b-1 or the outer surface 200b-2 through the connection part 310. In this structure, when an air injection unit (not shown) injects air into the space 210a between the inner surface 200b-1 and the outer surface 200b-2 through the air injection tube 300 as shown in FIG. 3A, the hip support 220 is lifted as shown in FIG. 3B. As a result, the left and right buttocks are lifted by the buttocks support parts 220a and 220b, and as a result, a container-shaped space A (recessed space) can be formed by the buttocks 210 and the connecting surface 200c as shown in Fig. 4. As will be described later, when the thighs are lifted by the thigh support part 222, a space A capable of receiving defecation and urination can be formed by the buttocks 210, the connecting surface 200c, and the thigh parts 212 and 214 corresponding to the thigh support part 222 as shown in Fig. 4.

[0015] Space A is a space that can receive defecation and urination, and since the buttocks are raised by the buttocks support parts 220a and 220b, the defecation and urination received in space A hardly come into contact with the patient's skin. In other words, the contact of the patient's skin with defecation can be minimized, and as a result, it can be hygienic. In the above description, air is injected into the space 210a between the inner surface 200b-1 and the outer surface 200b-2 to form the container-shaped space A, but the method of forming space A can be modified in various ways as long as the left and right buttocks can be raised to form space A. For example, the buttocks support parts 220a and 220b can be raised by mechanical drive.

[0016] According to an embodiment, the first thigh portion 212 may be formed with a first thigh support portion 222a, and the second thigh portion 214 may be formed with a second thigh support portion 222b. The thigh support portion 222 may be formed on the inner surface between the inner surface and the outer surface (inner space) of the thigh portion 212 or 214 as shown in FIG. 4, and may be lifted by air injected through the air injection tube 400. As a result, the left and right thighs may also be lifted by the thigh support portion 222. In this case, not only is the container-shaped space A better formed as shown in FIG. 4, but the thigh portions 212 and 214 on the rear surface 200b are in close contact with the patient's thighs, so that contaminated water due to defecation, urination, and washing is not leaked to the outside. As a result, it is possible to prevent the bed and the patient from becoming soiled.

[0017] According to an embodiment, a waist support part 224 may be additionally formed in the rear surface 200b near the waist. The waist support part 224 may also be formed on the inner surface of the rear surface 200b, and may be raised by air injected through an air injection tube (not shown). As a result, the waist support part 224 may be closely attached to the patient's waist, thereby preventing defecation, urination, and contaminated water from leaking out. Looking further at the rear surface 200b, a discharge pipe 230, at least one cleaning pipe 234, and a drying pipe 240 may be formed on the rear surface 200b. One end of the discharge pipe 230 may be connected to the collecting part 250, and the other end may be connected to the rear surface 200b through a connecting part 232, and may suck defecation, urination, and contaminated water. Here, the discharge pipe 230 may be detachable from the rear surface 200b through the connecting part 232.

[0018] According to one embodiment, the discharge pipe 230 may be formed corresponding to the space A that receives defecation and urination. Therefore, defecation, urination and contaminated water present in the space A may be collected in the collection unit 250 through the discharge pipe 230. According to one embodiment, a urination sensor is provided inside the discharge pipe 230, and when the urination sensor detects urination, the received urine may be automatically collected in the collection unit 250. For example, when the urination sensor detects urination, the collection unit 250 may automatically suck in and collect the urine.

[0019] According to an embodiment, a load sensor is provided under the collecting unit 250, and when the collecting unit 250 is filled with defecation, urine, or contaminated water above a preset value, the collecting unit 250 can be automatically emptied or can notify an administrator. Meanwhile, since the patient changes his / her diaper while lying on the bed, a hole is formed in a part of the bed, and the discharge pipe 230 can be connected to the collecting unit 250 through the hole in the bed. Of course, the discharge pipe 230 can be extended to the outside on the upper surface of the bed without a separate hole in the bed. The collecting unit 250 is not limited as long as it can suck in and collect the defecation, urine, and contaminated water received in the space A, and can include a suction means (not shown). One end of the cleaning pipe 234 is connected to the cleaning water unit 238, and the other end of the cleaning pipe 234 can be connected to the rear surface 200b through the corresponding connecting parts 236 and 242, and can be detachable.

[0020] According to one embodiment, the flushing tube 234 may be formed on the rear surface 200b at an outer portion of the space A. This is to prevent the flushing tube 234 from being clogged by feces and urination. However, the flushing tube 234 may be formed toward the anus since it must be used to flush feces. For example, the flushing tube 234 may be arranged toward the anus on the left or right side of the anus and may be formed to swing due to the water pressure.

[0021] According to an embodiment, the cleaning pipe 234 may have a structure for discharging cleaning water in a straight line as shown in FIG. 5A, or may have a plurality of nozzles formed therein so that the cleaning water is spread out and sprayed out as shown in FIG. 5B. Here, the cleaning pipe 234 may be formed flat on the rear surface 200b, or may be formed to protrude from the rear surface 200b as shown in FIG. 5. However, even if the cleaning pipe 234 protrudes, it may be formed flat on the rear surface 200b in normal times and may protrude from the rear surface 200b during defecation or urination. The cleaning water unit 238 may be a tank for storing cleaning water, and may include a pump function so that the cleaning water can be sprayed through the cleaning pipe 234. As another example, the cleaning water unit 238 may be directly connected to a water pipe for supply, and the cleaning pipe 234 may be detachable from the cleaning water unit 238.

[0022] According to one embodiment, the volume of wash water contained in the wash water unit 238 is automatically detected, and when it falls below a preset volume, wash water is automatically supplied to the wash water unit 238 to fill it. For example, a load sensor placed under the wash water unit 238 measures the load of the wash water unit 238, and a control unit (not shown) detects the current wash water volume of the wash water unit 238 based on the measurement result, and as a result, when the wash water volume is below the preset volume, wash water can be supplied to the wash water unit 238. As a result, a sufficient amount of wash water can be constantly discharged from the wash water unit 238, even if an administrator does not manage the wash water unit 238 separately.

[0023] The drying tube 240 has one end connected to a drying unit (not shown) and the other end connected to the rear surface 200b via a connecting unit 242, and is detachable. The drying unit can discharge dry air through the drying tube 234 to dry the buttocks washed with the wash water. Meanwhile, the drying operation can output weak air to the skin of the user not only when the user (e.g., the patient) has defecation or urination, but also during normal times when the user has not defecation or urination. Generally, since a patient spends time lying down continuously, skin diseases such as bedsores may occur. Therefore, in order to prevent such skin diseases, weak air can be continuously output to the skin of the patient. Here, the strength of the air output during normal times may be weaker than the strength of the air used for drying after urination.

[0024] According to another embodiment, a box including a defecation and urination discharge device (e.g., a vacuum pump) may be provided, and a fan may be installed in the box. In this case, the defecation and urination discharge device is connected to a discharge pipe and can suck in defecation and urination during defecation and urination and collect them in a collection unit. The fan may rotate continuously even when not in use, and when the fan rotates, air inside the defecation and urination underwear is sucked in through the discharge pipe and discharged to the outside through the fan of the box. In this case, outside air naturally enters the defecation and urination underwear, preventing skin diseases.

[0025] The fan can also rotate when the defecation and urination are sucked in through the exhaust pipe, and the fan speed during defecation and urination is faster than the fan speed during no defecation and urination. The defecation and urination sucked in through the exhaust pipe is collected in a collecting section by the rotation of the fan during defecation and urination, and the sucked air can be discharged to the outside through the fan. That is, during normal times when defecation and urination are not being handled, the fan rotates slowly to discharge the air inside the underwear for defecation and urination to the outside, thereby preventing skin diseases, and during defecation and urination, the fan rotates quickly to quickly process defecation and urination. Meanwhile, such a fan can be prevented from rotating at night.

[0026] According to yet another embodiment, a temperature sensor is installed in the box or outside the box, and the temperature sensor can measure the temperature of the air discharged through the exhaust pipe. As a result of the temperature measurement, the rotation speed of the fan can be increased as the temperature increases. That is, the temperature inside the undergarment for defecation and urination can be measured, and the rotation speed of the fan can be increased when the temperature is high and decreased when the temperature is low. Meanwhile, the rotation speed of the fan during defecation and urination treatment can be faster than the rotation speed of the fan when the temperature is normally high.

[0027] According to another embodiment, a hole may be provided beside the fan of the box, and an opening / closing part may be provided to open and close the hole. The opening / closing part may be closed except when defecation or urination is being treated. For example, when defecation or urination is being treated, the opening / closing part may be opened so that the air sucked in through the exhaust pipe can be more efficiently discharged to the outside. For example, if the hole is covered with a cloth, the cloth is naturally rolled up by the air, and the hole is opened.

[0028] Meanwhile, in normal times, when the fan exhausts air from the undergarment for defecation and urination to the outside through the exhaust pipe, the opening and closing part can close the hole. If the hole is open, the air introduced through the hole by the fan is exhausted to the outside, so the hole can be closed to prevent this. Meanwhile, when such a fan is used, it is possible to avoid outputting separate dry air to the user's buttocks, etc. In other words, the undergarment for defecation and urination using the fan does not need to be provided with a separate drying tube, etc. This is because the fan performs both the drying operation and the role of circulating air to prevent skin diseases.

[0029] According to yet another embodiment, a collecting section connected to a discharge pipe of the undergarment for defecation and urination is connected to the pump (e.g., a vacuum cleaner motor) or a box in which the pump is located through a pipe. As a result, defecation and urination or contaminated water collected through the discharge pipe is collected in the collecting section, and air existing in the collecting section is sucked in through the pipe by the pump and discharged to the outside through the pump or the fan. Of course, the pump performs a suction operation to collect defecation and urination or contaminated water through the exhaust pipe.

[0030] In summary, the diaper of the present invention forms a space A capable of receiving defecation and urination using the buttocks support parts 220a and 220b and the thigh support parts 222a and 222b, cleans the anus using cleaning water during defecation and urination, and the defecation, urination and cleaned waste (contaminated water) are collected through the collection part 250, and the buttocks and anus wetted by the cleaning water can be dried with dry air. Therefore, even if the patient defecates and urinates several times a day, there is no need to change the diaper, and even if the diaper is used continuously for a day or several days, it can be washed and reused. As a result, there is no need to change the patient's diaper frequently, which reduces the effort of family members and caregivers and reduces environmental pollution.

[0031] Meanwhile, when the amount of defecation, urination or contaminated water collected in the collecting section increases above a preset value or the amount of washing water in the washing section falls below a preset value, a notification is automatically provided to the manager. For example, a red light may be turned on in the equipment panel managed by the manager. For this purpose, a light emitting means for the collecting section and a light emitting means for washing water are separately provided in the equipment panel. Although not described above, the diaper of the present invention may further include an elastic part 216 that can be tightened around the waist, a sensor (not shown) that detects defecation and urination through moisture and gas generated during defecation and urination, an optical sensor that recognizes defecation and urination by light, and a sensor that detects defecation and urination by contact or weight when the defecation and urination are discharged.

[0032] The elastic portion 216 can loosen the tightness of the patient when the inside of the diaper expands due to air injection. Meanwhile, the elastic portion can also be formed in the thigh portion 214 of the diaper. The sensor can be formed in the inner space of the diaper, or on the inner surface of the diaper. That is, there is no positional restriction as long as the sensor detects defecation and urination. However, it is efficient to form the sensor under the buttocks. This is to enable immediate detection when defecation or gas comes out of the anus.

[0033] In addition, the upper end portion of the diaper may have a number of embossed protrusions or wrinkles, so that the contact between the inner surface of the diaper and the patient's skin is minimized and air can circulate naturally. Furthermore, a plug may be attached to the connection part 236 connected to the cleaning pipe 234. This is to close the hole of the connection part 236 when the cleaning pipe 234 is separated from the diaper. A massage function is added to the upper end portion of the diaper (corresponding to the waist). The patient's buttocks and thighs are lifted by injecting air and then lowered again, and the waist can be massaged. A heating function is added to the upper end portion of the diaper (corresponding to the waist).

[0034] The process of treating defecation and urination using the diaper of the present invention will be described in detail below. It is assumed that a patient is lying on a bed. First, the discharge pipe 230, the cleaning pipe 234, and the drying pipe 240 can be connected to the diaper after the patient wears the diaper. Of course, the discharge pipe 230, the cleaning pipe 234, and the drying pipe 240 can also be connected to the diaper before the patient wears the diaper. Then, the sensor detects the discharge of defecation and urination through the moisture, gas, weight, or opacity that blocks light by blocking the sensor when defecation and urination are accumulated. Then, when the discharge of defecation and urination is detected, the buttocks support parts 220a and 220b and the thigh support parts 222a and 222b are lifted by injecting air, and as a result, the buttocks and thighs of the patient are lifted, and a container-shaped space A can be formed by the buttocks 210 and the connecting surface 200c. At this time, since the defecation and urination are received in the space A, contact of the patient's skin with the defecation and urination is minimized.

[0035] Meanwhile, when the buttocks support parts 220a and 220b and the thigh support parts 222a and 222b are lifted, the waist support part 224 may also be lifted. Then, when it is determined that the discharge of defecation and urination is completed, the washing water is discharged to the anus through the washing pipe 234. Then, when the discharge of the washing water is completed, dry air is injected through the drying pipe 240 to dry the wet anus. Then, the contaminated water caused by the defecation and urination and the washing water is collected in the collecting part 250 through the discharge pipe 230. This collecting process may be performed before drying or may be performed together with drying. Then, when the collection is completed, the buttocks support parts 220a and 220b, the thigh support parts 222a and 222b, and the waist support part 224 may be returned to their normal positions. That is, the lifted buttocks support parts 220a and 220b, the thigh support parts 222a and 222b, and the waist support part 224 may be lowered. The fecal, urinary and waste water collected in the collection section 250 can then be discarded.

[0036] Fig. 6 is a schematic diagram of a portion of a diaper according to another embodiment of the present invention. As shown in Fig. 6(A), a hip support portion 600 and an inflatable portion 602 (e.g., a balloon) are laminated between the inner surface 200b-1 and the outer surface 200b-2 of the rear surface of the diaper. That is, unlike the previous embodiment in which only the hip support portion exists between the inner surface 200b-1 and the outer surface 200b-2, in this embodiment, the hip support portion 600 and the inflatable portion 602 exist between the inner surface 200b-1 and the outer surface 200b-2. According to another embodiment, the hip support portion 600 and the inflatable portion 602 may be entirely arranged on the inner side of the rear surface, or entirely arranged on the outer side of the rear surface, or one of the hip support portion 600 and the inflatable portion 602 may be arranged on the inner side of the rear surface and the other may be arranged on the outer side of the rear surface.

[0037] In this state, when air is injected into the inflatable portion 602 through the air injection tube 604, the inflatable portion 602 inflates and raises the buttocks support portion 600 as shown in FIG. 6B. As a result, the patient's buttocks can be raised. According to another embodiment, the inflatable portion 602 can be located above the buttocks support portion 600. In this case, the patient's buttocks can also be raised when the inflatable portion 602 inflates. Although not shown in FIG. 6, from the perspective of the thighs, the thigh support portion and the inflatable portion are layered between the inner surface 200b-1 and the outer surface 200b-2 of the rear surface of the diaper. Therefore, the thigh support portion can be raised by injecting air into the inflatable portion.

[0038] According to other embodiments, the thigh support part and the inflatable part may be arranged entirely on the inside of the rear surface, or entirely on the outside of the rear surface, or one of the thigh support part and the inflatable part may be arranged on the inside of the rear surface and the other on the outside of the rear surface. That is, as the buttocks support part 600 and the thigh support part rise, a space capable of receiving defecation and urination is formed. The description of such a space has been given above and will be omitted.

[0039] According to another embodiment, the diaper (underwear) may include a first sub-diaper 610 (first sub-underwear) and a second sub-diaper 612 (second sub-underwear) as shown in FIG. 6C. That is, a second sub-diaper 612 having an internal space is connected to the outer surface of the first sub-diaper 610 having the structure as shown in FIG. 2. For example, the second sub-diaper 612 may be made of cloth and an end of the second sub-diaper 612 may be connected to the outer surface of the first sub-diaper 610, thereby forming a space inside the second sub-diaper 612, and the second sub-diaper 612 may be formed only in the buttocks portion. Here, the cloth may be attached to the first sub-diaper 610 in the form of a hook-and-loop fastener. That is, the second sub-diaper 612 may be attached to the first sub-diaper 610 in a fixed or detachable manner.

[0040] In this structure, the patient's buttocks are positioned within the first sub-diaper 610, and the buttocks support section 600 and the inflatable section 602 are positioned within the second sub-diaper 612. However, the stacking order of the buttocks support section 600 and the inflatable section 602 is irrelevant. For example, the inflatable section 602 can be positioned below the buttocks support section 600, or can be positioned above the buttocks support section 600. In this case, when the inflatable section 602 inflates, the buttocks are lifted to form a space capable of receiving defecation and urination. Of course, the thigh support section and the corresponding inflatable section can also be positioned within the second sub-diaper 612.

[0041] According to another embodiment, as shown in FIG. 6D, a third sub-diaper 620 (third sub-underwear) is formed inside the first sub-diaper 610, and the hip support section 600 and the inflation section 602 can be located in the third sub-diaper 620. Of course, the thigh support section and the corresponding inflation section can also be located in the third sub-diaper 620. According to yet another embodiment, the hip support section 600 and the thigh support section can be located in the first sub-diaper 610, and the corresponding inflation section can be located in the second sub-diaper 612 or the third sub-diaper 620. However, it is efficient from the viewpoint of structure that the hip support section 600 and the inflation section 602 are located together in the second sub-diaper 612.

[0042] On the other hand, the expansion part alone can form a space capable of receiving defecation and urination without the buttocks support part and the thigh support part, but if only the expansion part is present, the patient's urine may flow out when air is not injected into the expansion part. On the other hand, if the buttocks support part and the thigh support part are present together with the expansion part, a basic space is formed by the buttocks support part and the thigh support part even when air is not injected into the expansion part. As a result, the patient's urine is not discharged to the outside even when air is not injected into the expansion part. Therefore, it is efficient to have the buttocks support part, the thigh support part and the expansion part together. In addition, since these support parts have a basic height, it is possible to separate the skin from the bottom surface of the diaper, and it is also possible to suppress skin diseases such as bedsores.

[0043] According to another embodiment, a space separating member is attached to the inside of the diaper, so that the diaper includes two spaces. The upper space of the spaces may receive the user's buttocks, and the lower space may include the support part and the inflatable part. In this case, the space separating member is detachable from the diaper.

[0044] Fig. 7 is a schematic view of a portion of a diaper according to another embodiment of the present invention, and Fig. 8 is a view showing a support member according to an embodiment of the present invention. Fig. 9 is a view showing the operation of a buttocks support part according to an embodiment of the present invention, and Fig. 10 is a view showing the operation of a thigh support part according to an embodiment of the present invention. Fig. 11 is a view showing a tube structure according to an embodiment of the present invention. However, for ease of explanation, Fig. 7 shows only the rear surface of the diaper.

[0045] 7, the support member 702 may be located on the buttocks 700a or the buttocks 700a and thighs of the inner surface of the rear surface 700 of the diaper, and the expansion parts 720, 722, and 724 may be arranged between the inner surface 700a and the support member 702. However, the expansion parts 722 and 724 may be located on the support member 702 or may be located on the lower outer surface of the rear surface (700) of the diaper. The support member 702 may include a buttocks support part 710, a first thigh support part 712, a second thigh support part 714, a first connecting part 800 connecting the buttocks support part 710 and the first thigh support part 712, and a second connecting part 802 connecting the buttocks support part 710 and the second thigh support part 714, as shown in FIG. 7 and FIG. 8. That is, the hip support portion 710 and the thigh support portions 712 and 714 are integrally mounted. Of course, the hip support portion 710 and the thigh support portions 712 and 714 can also exist as separate members without the connecting portions 800 and 802, respectively.

[0046] According to one embodiment, the hip support section 710 and the thigh support sections 712 and 714 have a height greater than that of the connecting sections 800 and 802, and a cleaning pipe or the like is arranged across the connecting sections 800 and 802. When the operation of the hip support section 710 is considered with reference to (A) and (B) of FIG. 9, when air is injected into the expansion section 720 located between the hip support section 710 and the inner surface 700a-1 of the hip section 700a, the expansion section 720 expands, and as a result, the hip support section 710 rises and the hips are lifted. When the operation of the thigh support section 1010 is considered with reference to (A) and (B) of FIG. 10, the thigh support section 1010 is arranged on the inner surface 700b-1 of the thigh section of the rear surface 700 of the diaper, and the expansion section 1012 is arranged below the outer surface 700b-2 of the thigh section. In this arrangement, when air is injected into the inflatable portion 1012 via the air injection tube 1014, the thigh support portion 1010 is lifted, resulting in the thighs rising.

[0047] Of course, the expansion part and the thigh support part 1010 may be sequentially positioned on the inner surface 700b-1. However, the structure of FIG. 10 is more advantageous in moving urine, etc., toward the exhaust pipe because the thigh part itself is also raised. Overall, as the buttocks support part 710 and the thigh support part 1010 are raised, a space for receiving defecation and urination may be naturally formed. Although the exhaust pipe, cleaning pipe, and drying pipe are not mentioned in the above-mentioned embodiment, they are the same or similar to the contents of FIG. 1 to FIG. 6, so they are not described separately. However, the exhaust pipe, cleaning pipe, and drying pipe may be directly connected to the diaper as in the above-mentioned embodiment, but may also be connected to a pipe structure 1100 formed on the inner surface of the diaper as shown in FIG. 11.

[0048] For example, the tube structure 1100 may be made of hard plastic and may include at least one hole 1102 to which a drain pipe, a cleaning pipe or a drying pipe may be fixedly connected. That is, the drain pipe, the cleaning pipe or the drying pipe may be connected to the tube structure 1100 without being directly connected to the diaper. Of course, the tube structure 1100 may have a structure that connects an external tube that enters the diaper with an internal tube located inside. That is, as long as the tube structure 1100 can connect a drain pipe, a cleaning pipe or a drying pipe, the connection structure and method may be modified in various ways. According to another embodiment, the support member and at least one expansion portion located at the upper or lower part of the support member may be located in the second sub-diaper 612 or the third sub-diaper 620 of the diaper including the first sub-diaper 610 and the second sub-diaper 612 or the third sub-diaper 620 as shown in Fig. 6C and 6D. Of course, the support member or the expansion portion can be located in the first sub-diaper 610 and the expansion portion or the support member can be located in the second sub-diaper 612 .

[0049] Fig. 12 is a diagram illustrating a schematic view of a diaper according to another embodiment of the present invention, Fig. 13 is a diagram illustrating the structure of an expansion part and the discharge structure for defecation and urination according to one embodiment of the present invention, Fig. 14 is a diagram illustrating the concept of the discharge structure for defecation and urination according to another embodiment of the present invention, and Fig. 15 is a diagram illustrating the structure of an expansion part according to another embodiment of the present invention, however, the same reference numerals are used for the same components as those in Figs. 2 to 11 and the description thereof will be omitted.

[0050] Referring to FIG. 12, the underwear (diaper) may additionally include a second exhaust pipe 1200 and an air jet unit 1202 in addition to the first exhaust pipe 230 shown in FIG. 2. The first exhaust pipe 230 may be connected to the center of the rear surface of the diaper, and the second exhaust pipe 1200 may be connected to the outside in the direction of the expansion unit that lifts the buttocks support unit or the thigh support unit. Specifically, as shown in FIG. 13, the expansion unit that lifts the buttocks support unit or the thigh support unit may include a first expansion unit 1300, a second expansion unit 1302, and a connecting unit 1304. Before air is injected, the expansion units 1300 and 1302 are in an uninflated state as shown in FIG. 13(A), and when air is injected, they may be inflated as shown in FIG. 13(B).

[0051] According to one embodiment, the connecting part 1304 has a width smaller than that of the expanding part 1300 or 1302 and may be connected to the upper ends of the expanding parts 1300 and 1302. As a result, when the expanding parts 1300 and 1302 are expanded, a discharge passage is formed at the lower end of the connecting part 1304. Therefore, as shown in FIG. 14, the defecation, urination or contaminated water in the space where the defecation and urination are collected may be discharged through the first discharge pipe 230, and may be discharged to the outside through the discharge passage at the lower end of the connecting part 1304 and the second discharge pipe 1200. According to another embodiment, when the expanding part is located on the support part, a lower part of a part of the support part may be formed in a concave shape to form a discharge passage. Although a structure for injecting air is not shown in the above description, air may be injected into one of the expanding parts 1300 and 1302, and the injected air may be transferred to the other expanding part through the connecting part 1304. As a result, when air is injected into one of the expansion parts 1300 or 1302, both of the expansion parts 1300 and 1302 can be expanded. Of course, air can also be injected into each of the expansion parts 1300 and 1302. In the structure of FIG. 2, it was difficult to discharge a large amount of feces or contaminated water when it was generated. Therefore, in order to smoothly discharge such feces and contaminated water, a separate discharge passage is formed at the lower end of the connecting part 1304 of the expansion parts 1300 and 1302.

[0052] In addition, in the above description, it has been described that the exhaust passage is formed only through the expansion portion that raises either the buttocks support portion or the thigh support portion, but the exhaust passage can also be formed in the buttocks support portion and all of the thigh support portions.

[0053] According to another embodiment, in order to lift the buttocks support portion and the thigh support portion, the inflatable portion may have a "U" shape as shown in Fig. 15. In this case, too, a connecting portion 1404 connects the first inflatable portion 1400 and the second inflatable portion 1402, and may be connected to the upper ends of the inflatable portions 1400 and 1402. As a result, a discharge passage may be formed through the lower end of the connecting portion 1404. Here, the first inflatable portion 1400 may lift the buttocks and a part of the thighs, and the second inflatable portion 1402 may lift the remaining part of the thighs.

[0054] According to another embodiment, the device may further include a wind jetting unit 1202 for jetting wind to allow feces, urine, or contaminated water to be discharged smoothly into the discharge passage at the lower end of the connecting part. That is, the wind jetting unit 1202 can jet wind toward the discharge passage at the lower end of the connecting part so that feces and contaminated water flow into the discharge passage. In the case of elderly patients, they discharge feces and urine several tens of times a day, so in the structure of FIG. 2, a large amount of cleaning water must be jetted, which generates a large amount of contaminated water, and therefore multiple pumps must be operated multiple times. Generally, in a hospital, multiple patients are hospitalized in one room, so the operation of such pumps can generate a lot of noise, which may cause inconvenience to other patients. Therefore, if low-noise wind is used to assist in the discharge of feces or contaminated water, the number or time of pump operations for jetting cleaning water or jetting feces and urine can be reduced, thereby reducing noise.

[0055] Meanwhile, without providing a separate air jet unit 1202, the direction of the drying pipe 240 may be changed so that the air blows in the direction of the discharge passage after drying the buttocks through the drying pipe 240. According to still another embodiment, a protective material such as vinyl may be arranged in the discharge passage at the lower end of the connecting part. This is to minimize contamination, dirt and odor caused by the movement of feces, urination or contaminated water.

[0056] 16 and 17 are drawings illustrating a diaper according to another embodiment of the present invention. Referring to FIG. 16, the expansion parts 1600 and 1602 have a structure in which the expansion parts 1600 and 1602 are separated from each other without a connecting part between them. In this case, when the expansion parts 1600 and 1602 are expanded, a discharge passage is formed naturally. The discharge passage is connected to a discharge pipe, and feces, urine, or contaminated water is discharged to the outside through the discharge passage and the discharge pipe. Referring to FIG. 17, the expansion parts 1700 and 1702 have a "U" shape, and the expansion parts 1700 and 1702 may have a structure in which the expansion parts 1700 and 1702 are separated from each other without a connecting part between them. As a result, when the expansion parts 1700 and 1702 are expanded, a discharge passage is formed naturally between the expansion parts 1700 and 1702.

[0057] FIG. 18 is a diagram illustrating the structure of a sensor according to an embodiment of the present invention. The sensor 1800 is a sensor that can detect defecation and urination, and can be located on the inner surface of the rear surface of the diaper. However, there is no positional restriction on the sensor 1800 as long as it can detect defecation and urination. On the other hand, if the diaper includes a first sub-diaper and a second sub-diaper, the sensor is arranged in the first sub-diaper. According to an embodiment, the sensor 1800 can include a base 1810, a lid 1812, a first electrode 1814, and a second electrode 1816 as shown in FIG. 18. Although not shown, there can be wiring connecting the electrodes 1814 and 1816 to a power source (not shown).

[0058] The first electrode 1814 is formed on the base 1810 and covered by the lid 1812. That is, the lid 1812 is formed on the first electrode 1814 and covers the first electrode 1814. The second electrode 1816 can be formed on the base 1810 and located outside the lid 1812. That is, the first electrode 1814 is covered by the lid 1812, and the second electrode 1816 is not covered by the lid 1812. The sensor 1800 having such a structure is located, for example, on the inner surface of the rear surface, and can detect a change in resistance to determine whether the patient has defecate or urinate. If it is determined that defecation or urination has been discharged, a cleaning operation is performed.

[0059] The cover 1812 is formed in a convex shape on the first electrode 1814, and a hole is formed thereon. Without the cover 1812, the male private parts or the female genital area may come into contact with the electrodes 1814 and 1816, and in that case, the electrodes 1814 and 1816 may be electrically connected due to moisture in the private parts or genital area, resulting in a malfunction. That is, the sensor 1800 may malfunction as if defecation or urination has been discharged even when defecation or urination has not been discharged. In order to solve this problem, the cover 812 is formed on the first electrode 1814 to prevent the private parts or genital area from directly contacting the first electrode 1814. However, since urine, etc. must flow over the first electrode 1814 when defecation or urination is discharged, a hole through which the urine, etc. can pass may be formed in the cover 1812. As a result, when defecation or urination occurs, urine flows through the hole to the first electrode 1814, electrically connecting the electrodes 1814 and 1816, causing a change in the resistance of the sensor 1800. The sensor 1800 detects defecation or urination through this change in resistance. Meanwhile, when such a lid 1812 is formed, the crotch is retracted by the length of the high protrusion, so the position where feces accumulates during excretion is also retracted. As a result, the excreted feces can be stably accumulated in the bottom plate, which will be described later.

[0060] According to another embodiment, the hole may not be formed in the lid 812, and for example, the lid 812 may be made of a material such as leather. Even if no hole is formed, the electrodes 1814 and 1816 can be electrically connected by urine or the like flowing along the lid 812. Of course, the sensor 1800 is not limited to the structure of FIG. 18 as long as it can detect defecation and urination.

[0061] FIG. 19 is a diagram illustrating the structure and arrangement of a bottom plate according to one embodiment of the present invention, and FIG. 20 is a diagram illustrating the structure and arrangement of a bottom plate according to another embodiment of the present invention. The bottom plate 1900 (discharge assistance portion or auxiliary plate) is arranged on the inner surface of the rear surface of the diaper, the inner surface of the first sub-diaper 610, the second sub-diaper 612, or the third sub-diaper 620, for example, near the crotch area. Of course, the bottom plate 1900 can also be arranged outside the diaper. Such a bottom plate 1900 can have flat upper and lower surfaces. As a result, when the bottom plate 1900 is arranged on the inner surface of the rear surface of the diaper, for example, the feces can be stably collected, and the feces and urine received in the space can slide smoothly toward the discharge outlet. That is, the bottom plate 1900 can assist the feces and urine to be discharged smoothly toward the discharge outlet. In addition, the bottom plate 1900 can stably maintain the space for receiving defecation and urination, which is formed by the buttocks support portion, the first expansion portion, the thigh support portion, and the expansion portion. Generally, a patient lies on a bed, and a blanket can be placed between the patient and the bed. In this case, the blanket can cause the diaper portion, especially the portion where the space is formed, to protrude in a convex shape, which can result in a smaller space for receiving defecation and urination.

[0062] On the other hand, when the bottom plate 1900 is present, the diaper portion corresponding to the space can be kept flat at all times regardless of the bedding, and as a result, a sufficient space for receiving defecation and urination can be secured. However, in order to achieve this function, the bottom plate 1900 needs to be stably fixed, and for this purpose, the bottom plate 1900 has a structure in which wings 1912 and 1914 are formed on both sides of the body 1910, and the wings 1912 and 1914 are pushed by the support member or the inflatable portion. Of course, a part of the body 1910 is pushed by the support member or the inflatable portion. In this case, the bottom plate 1900 is pushed by the patient's weight, and the bottom plate 1900 can be stably fixed and can be kept horizontal with the bottom. At this time, the body 1910 is located in the space between the side members 1932 and 1934 of the "U"-shaped support member, and the wings 1912 and 1914 are pushed by the side members 1932 and 1934.

[0063] Meanwhile, the bottom plate 1900 may be inserted between the support member and the inflatable portion. According to another embodiment, as shown in FIG. 20, a hole or a transparent portion 2000 may be formed in a part of the bottom plate 1900, particularly in the part where the feces falls, and the transparent portion (2000) is preferable to the hole in terms of receiving the feces. This is for detecting the feces. Specifically, the light emitting portion and the light receiving portion are arranged symmetrically based on the bottom plate 1900 inside the diaper, and the light output from the light emitting portion passes through the transparent portion 2000 of the bottom plate 1900 and enters the light receiving portion, and the light receiving portion can output the detection result to the outside. When feces is not excreted or when urination occurs, the transparent portion 2000 maintains a transparent state, but when feces is excreted, the transparent portion 2000 becomes opaque. Whether or not feces is excreted can be detected by such a difference. Of course, the opaque transparent portion 2000 changes back to transparent when washed.

[0064] Meanwhile, the remaining part of the bottom plate 1900 except for the transparent portion 2000 may be opaque. In such a structure of the bottom plate 1900, the support member and the inflation portion may be arranged on the inner surface of the first sub-diaper 610, and the bottom plate 1900 may be located below the inflation portion on the inner surface, or the support member may be located on the inner surface of the first sub-diaper 610, and the inflation portion may be located in the second sub-diaper 612, and the bottom plate 1900 may be located below the support member on the inner surface. Alternatively, when the support member and the inflation portion are located in the second sub-diaper 612, the bottom plate 1900 may be located on the inner surface of the first sub-diaper 610, or may be located below the support member and the inflation portion in the second sub-diaper 612.

[0065] Meanwhile, the light emitting unit and the light receiving unit are arranged symmetrically based on the bottom plate 1900, and a part of the first sub diaper 610 is formed transparent to allow light to pass through, but they may be located together on one side of the bottom plate 1900. In this case, a reflective part may be formed on the bottom plate 1900 instead of the transparent part 2000. Also, a solar panel capable of generating electricity when the light receiving unit detects light may be additionally formed inside the diaper.

[0066] Furthermore, by forming a plurality of transparent parts at a distance on the bottom plate 1900 and the diaper, it is possible to measure whether the area where the stool falls is narrow or wide, and as a result, the amount of stool can be measured to some extent. Of course, the amount of light passing through the transparent part 2000 changes depending on the wateriness of the stool, so the quality of the stool can also be measured through this amount of light. In this case, one light emitting part can be used, but multiple light emitting parts can also be used.

[0067] Meanwhile, the transparent portion of the diaper may be made of a transparent material, or a hole may be formed in the diaper and a transparent member (e.g., a transparent plastic plate) may be attached thereon. According to another embodiment, the transparent portion may be formed in a part of the diaper without a bottom plate, and the light-emitting unit and the light-receiving unit may be arranged based on the transparent portion to detect defecation. Of course, a reflector may be formed in a part of the diaper, and defecation may be detected using light reflection. In this case, the light-emitting unit and the light-receiving unit are arranged in the same direction based on the reflector. In this case, an illuminance sensor or a solar light sensor may be used as the light-receiving unit.

[0068] Meanwhile, in the above description, the base plate is an integral structure, but it may be implemented as a plurality of separate sub-base plates. The sub-base plates may be arranged side by side. When such separate sub-base plates are used, the sub-base plates can naturally support the user's buttocks not only when the user is lying on the bed but also when the user is sitting on the bed.

[0069] FIG. 21 is a drawing illustrating a schematic view of a portion of an undergarment for defecation and urination according to one embodiment of the present invention, FIG. 22 is a drawing illustrating the upper surface of a bottom plate according to another embodiment of the present invention, FIG. 23 is a drawing illustrating the underside of the bottom plate of FIG. 22, FIG. 24 is a drawing illustrating a structure in which a support part according to one embodiment of the present invention is placed on a bottom plate, FIG. 25 is a drawing illustrating a schematic view of a portion of a first sub-diaper or a portion where the first sub-diaper and a second sub-diaper contact each other according to one embodiment of the present invention, FIGS. 26 to 27 are drawings illustrating a schematic view of an arrangement of a support part, a bottom plate and an installation structure according to one embodiment of the present invention, FIG. 28 is a drawing conceptually illustrating an undergarment for defecation and urination according to yet another embodiment of the present invention, and FIG. 29 is a drawing conceptually illustrating an undergarment for defecation and urination according to yet another embodiment of the present invention.

[0070] The undergarment for defecation and urination of the present invention can have two structures. As a first structure, the undergarment for defecation and urination has a structure in which a space separating member 2102 is formed inside an undergarment member 2100 as shown in FIG. 21. In this case, the undergarment for defecation and urination has a first space 2150 on the upper side and a second space 2152 on the lower side by the space separating member 2102. The first space 2150 accommodates the user's buttocks, etc., and the second space 2152 includes the support part 2104, the expansion part 2120, and the bottom plate 2106. In this case, the expansion part 2120 can be located below or above the support part 2104, and the bottom plate 2106 is made of plastic.

[0071] Also, the space separating member 2102 may be detachably attached to the underwear member 2100. When the space separating member 2102 is detachably mounted in this manner, after the treatment of defecation and urination, only the space separating member 2102 can be separated and washed, and then reattached for use. That is, the defecation and urination underwear can be kept clean by only washing the space separating member 2102. As a second structure, the defecation and urination underwear may include a first sub underwear 2800 into which the buttocks and thighs are inserted, and a second sub underwear 2802 connected to a lower part of the first sub underwear 2800, as shown in FIG. 28. In this case, the second sub underwear 2802 may include a support part 2104, an expansion part 2120, and a bottom plate 2106. In this case, the expansion part 2120 may be located at the lower part or upper part of the support part 2104. Here, the interior space of the first sub-undergarment 2800 can correspond to the first space 2150 of the first structure, and the interior space of the second sub-undergarment 2802 can correspond to the second space 2152 of the first structure.

[0072] The structure and operation of the underwear for defecation and urination will be described in detail below based on the first structure. The operation of the second structure is similar to that of the first structure, except that in the second structure, the lower surface of the first sub-underwear 2800 or the portion where the first sub-underwear 2800 and the second sub-underwear 2802 contact each other is made of a transparent material. In the second space 2152, the support portion 2104 and the expansion portion 2120 are sequentially arranged on the bottom plate 2106. According to one embodiment, the bottom plate 2106 may include a first sub-bottom plate 2200 and a second sub-bottom plate 2202 separated from each other as shown in FIG. 22. When the sub-bottom plates 2200 and 2202 are separated in this manner, the user can maintain comfort not only when lying down but also when sitting. Of course, although the above content refers to two sub-bottom plates 2200 and 2202, the underwear may be composed of three or more sub-bottom plates. Such a bottom plate 2106 may also be coupled to the lower surface of the underwear member 2100 or the lower inner surface of the second underwear sub-layer 2802 .

[0073] According to one embodiment, a "U" shaped vertical portion 2210 may be formed on the first sub-bottom plate 2200, and a "￢" shaped vertical portion 2212 may be formed on the second sub-bottom plate 2202. In this case, the opposing portions of the vertical portions 2210 and 2212 are arranged side by side. As a result, a space 2230 is formed by the vertical portions 2210 and 2212 as shown in Fig. 21. However, a hole 2240 is formed in a part of the space 2230 formed by the vertical portions 2210 and 2212. The hole 2240 corresponds to a passage for discharging defecation and urination.

[0074] In such a structure of the bottom plate 2106, a "U"-shaped support portion 2104 may be placed on the bottom plate 2106 as shown in Fig. 24. For example, the support portion 2104 may be arranged on the bottom plate 2106 along the vertical portions 2210 and 2212 of the bottom plate 2106 and outside the vertical portions 2210 and 2212. That is, the support portion 2104 may surround the vertical portions 2210 and 2212. Specifically, the portion of the support portion 2104 corresponding to the buttocks may be arranged on the second sub-bottom plate 2202, and the portion corresponding to the thighs may be arranged across the second sub-bottom plate 2202 and the first sub-bottom plate 2200.

[0075] With such a support portion 2104 arranged on the bottom plate 2106, the expansion portion 2120 can be arranged on the support portion 2104. A structure in which the support portion 2104 and the expansion portion 2120 are arranged on the bottom plate 2106 is arranged in the second space 2152, and the user's hips and thighs are arranged above the first space 2150, so that when the expansion portion 2120 is inflated, the hips or thighs in the first space 2150 can be raised. In this case, the bottom plate 2106 and the support portion 2104 maintain their original state even when the expansion portion 2120 is inflated.

[0076] According to one embodiment, there may be a buttocks expansion portion and a thigh expansion portion, the buttocks expansion portion may be located at the upper or lower part of the support portion 2104 in the second space 2152, and the thigh expansion portion may be located at a portion corresponding to the thighs on the outside of the defecation and urination undergarment. In this case, the thigh support portion may be located on the inside of the defecation and urination undergarment. Of course, the thigh expansion portion may also be located in the second space 2152 of the defecation and urination undergarment, but it is more efficient to locate the thighs on the outside of the defecation and urination undergarment because it can sufficiently lift the thighs. If the thigh expansion portion is located inside the defecation and urination undergarment, the thighs cannot be sufficiently lifted even if the thigh expansion portion is inflated, but if the thigh expansion portion is located outside the defecation and urination undergarment, the thighs can be sufficiently lifted. As a result, the received defecation and urination can be discharged better.

[0077] According to another embodiment, the expansion portion 2120 is present on the first support portion 2104, and a second support portion (sub-support portion) may be additionally present on the expansion portion 2120 in the second space 2152. The second support portion may play a role of supporting the user's buttocks comfortably. To this end, the strength of the second support portion may be weaker than the strength of the first support portion 2104, and may have an embossed structure. That is, the first support portion 2104 may be a hard support portion, and the second support portion may be a soft support portion. According to yet another embodiment, the second support portion may be present in the expansion portion 2120 present on the first support portion 2104. The second support portion may play a role of supporting the user's buttocks softly when the expansion portion 2120 is not expanded. In this case, the strength of the second support portion may be weaker than the first support portion 2104. According to yet another embodiment, there may be supporting portions at the upper and lower parts of the expansion portion 2120, and there may also be a supporting portion inside the expansion portion 2120. According to yet another embodiment, a second supporting portion and the expansion portion may be sequentially positioned on the first supporting portion. In this case, the strength of the second supporting portion may be weaker than the strength of the first supporting portion. That is, additional supporting portions may be present at the upper and lower parts or inside the expansion portion 2120, and the strengths or materials of the supporting portions may be different from each other.

[0078] Meanwhile, the underwear for defecation and urination of this embodiment can detect defecation and urination using an optical sensor. For this structure, at least one optical receiver 2204 is formed in a space 2230 formed in a vertical part 2210 of a first sub bottom plate 2200 as shown in Fig. 22, and the space separating member 2102 can include a transparent part 2102a and a connecting part 2102b as shown in Figs. 21 and 25. In the second structure, a part where the first sub undergarment 2800 and the second sub undergarment 2802 contact each other or a part of the first sub undergarment 2800 corresponding to the space 2230 can be made of a transparent material that allows light to pass through. The transparent part 2102a of the space separating member 2102 or the transparent part of the first sub undergarment 2800 can be located corresponding to the space 2230 formed in the vertical parts 2210 and 2212 of the bottom plate 200.

[0079] According to an embodiment, as shown in Fig. 22 and Fig. 27, the optical transmitter 2206 may be formed on the vertical portion 2210 of the first sub-bottom plate 2200. As a result, the light output from the optical transmitter 2206 may pass through the transparent portion 2102a and enter the first space 2150, and then may be incident on the optical receiver 2204 in the second space 2152 via the transparent portion 2102a. If there is feces on the transparent portion 2102a, the amount of light incident on the optical receiver 2204 is reduced. In other words, it is possible to know whether the user has excreted feces, the wateriness of the feces, and the like through the optical sensor.

[0080] Also, as shown in FIG. 24, the optical receivers 2204 may be arranged side by side on the first sub-bottom plate 2200 with a space between them. By arranging the optical receivers 2204 in this manner, the amount of defecation can be roughly grasped. In FIG. 24, when the three optical receivers 2204 do not receive light or receive only a small amount of light, it indicates that the amount of defecation is large, and when only one optical receiver 2204 receives only a small amount of light, it indicates that the amount of defecation is small. According to another embodiment, as shown in FIG. 21, the installation structure 2108 having an "inverted T" shape may be arranged on the first sub-bottom plate 2200 in the first space 2150. In this case, an optical transmitter (red dotted line portion) may be formed on the installation structure 2108. As a result, the light output from the optical transmitter may be incident on the optical receiver 2204 through the transparent portion 2102a.

[0081] According to yet another embodiment, the optical transmitter may be located outside the defecation and urination underwear, and the optical receiver may be located inside the defecation and urination underwear. In this case, the defecation and urination underwear may be formed with a transparent part that allows the light output from the optical transmitter to enter the inside. That is, the light output from the optical transmitter is input to the defecation and urination underwear and is received by the optical receiver after passing through or reflecting defecation and urination. In this way, the presence or absence of defecation and urination is detected. According to yet another embodiment, both the optical transmitter and the optical receiver may be located outside the defecation and urination underwear. In this case, the defecation and urination underwear may include a first transparent part through which the light output from the optical transmitter can enter and a second transparent part through which the light passed through or reflected by defecation and urination can pass.

[0082] Looking at the installation structure 2108 in detail, the installation structure 2108 may include a bottom 2108a and a support 2108b. Here, the bottom 2108a may be arranged on the first sub-bottom plate 2200, and the support 2108b may be arranged to cross the bottom 2108a, preferably vertically. According to an embodiment, a rear space 2140 in which a bottom washing pipe and a body washing pipe can be accommodated is formed on the rear surface of the support 2108b. Holes 2130 and 2132 may be formed on the lower and upper sides of the front surface, respectively, at least one first nozzle 2110 is formed on the bottom 2108a, and a second nozzle 2112 may be exposed to the outside through the bottom 2108a.

[0083] At this time, the first nozzle 2110 and the second nozzle 2112 are respectively connected to the bottom washing pipe inserted into the rear space 2140 of the support part 2108b. As a result, when water is sprayed through the first nozzle 2110, the defecation and urination move in the front direction, and when water is sprayed through the second nozzle 2112, the defecation and urination move in the side direction. According to an embodiment, a hole is formed in a part (red dotted line in FIG. 25) of the transparent part 2102a of the space separating member 2102, and a hole 2400 is formed through the support part 2104 corresponding to the hole. The hole and the hole 2400 correspond to the hole 2240 formed in a part of the space 2230 formed by the vertical parts 2210 and 2212. As a result, the defecation and urination moved by the nozzles 2110 and 2112 can be discharged to the outside through the hole of the transparent part 2102a, the hole 2400 of the support part 2104, and the discharge pipe. Here, the exhaust pipe is connected to the underwear member 2100 at a portion corresponding to the hole 2400 of the support part 2104 .

[0084] A first body nozzle connected to a body cleaning pipe accommodated in a rear space 2140 of the support part 2108b is formed in a hole 2130 formed in the lower side of the support part 2108b, and a second body nozzle connected to the body cleaning pipe is formed in a hole 2132 formed in the upper side. The first body nozzle can perform a role of cleaning the user's buttocks, and the second body nozzle can perform a role of cleaning the genitals. According to an embodiment, the entire support part 2108b or the upper part can be made of a flexible material. This is to stably maintain the support part 2108b regardless of the user's posture. According to an embodiment, an optical transmission part can be provided on the front surface of the support part 2108b, and the optical transmission part can be formed between the holes 2130 and 2132, for example, as shown by the red dotted line in FIG. 21. The light output from the optical transmitter may be incident on the optical receiver (2204) located on the first sub-bottom plate 2200 through the transparent portion 2102a of the space separating member 2102 or the transparent portion of the lower surface of the first sub-bottom plate 2800. In this case, the optical receiver 2206 formed on the vertical portion 2210 of the first sub-bottom plate 2200 may not be present.

[0085] According to an embodiment, for example, the transparent portion 2102a of the space separating member 2102 includes a metal body 2502 as shown in FIG. 25, and a magnet is formed on the bottom surface of the bottom plate 2106, for example, the first sub-bottom plate 2200, as shown in FIG. 23. As a result, the transparent portion 2102a of the space separating member 2102 is stably attached to the space 2230 of the bottom plate 2106. Of course, other methods can be used besides the method using a magnet, as long as the transparent portion 2102a is stably attached to the bottom plate 2106. For example, at least a part of the transparent portion 2102a can be fitted into a groove formed in the bottom plate 2106, or the transparent portion 2102a can be bonded to the bottom plate 2106.

[0086] Meanwhile, in the above description, it has been described that the space separating member 2102 has a transparent portion 2102a, or a portion of the lower surface of the first sub undergarment 2800 is transparent, but the space separating member 2102 and the lower surface of the first sub undergarment 2800 may not have a transparent portion. In this case, the discharge of defecation and urination may not be detected using an optical sensor, but may be detected by another method such as a load sensor. Of course, a hole may be formed in the space separating member 2102 and an optical sensor may be used.

[0087] In the above description, the space separating member 2102 is used, but as shown in FIG. 29, the inside of the underwear member 2900 may be one space without the space separating member, and the bottom plate 2902, the support part 2904, the inflatable part 2906, and the user's buttocks may be accommodated in the space. For example, a connecting member (e.g., cloth 2908) connected to both ends of the inside of the underwear member 2900 may be connected to the vertical part of the bottom plate 2902, and no transparent part may be present in the inner space of the bottom plate 2902. That is, although the connecting member 2908 connected to the inside of the underwear member 2900 exists, the connecting member 2908 may not completely separate the inner space of the underwear member 2900 into two spaces. In this case, defecation and urination are received in the space formed by the vertical part of the bottom plate 2902. Of course, the optical sensor and the installation structure may be formed similarly to the above description.

[0088] For example, the base plate 2902 may include a first sub-base plate and a second sub-base plate separated from each other, the first sub-base plate and the second sub-base plate may be arranged continuously, a vertical portion may be formed on one surface of the first sub-base plate and the second sub-base plate, the specific space may be formed by the vertical portion, and a support portion 2904 may surround the vertical portion. Also, at least one optical receiving portion may be formed on the first sub-base plate, an optical transmitting portion may be formed on one of the vertical portions of the sub-base plate, and light output from the optical transmitting portion may be incident on the optical receiving portion, and the discharge of defecation and urination may be detected through the transmission and reception of the light.

[0089] Further, the installation structure arranged on the bottom plate 2902 includes a bottom and a support arranged crossing the bottom, a bottom washing pipe is accommodated in a rear space of the support, a first nozzle connected to the bottom washing pipe is formed in the bottom, and a second nozzle connected to the bottom washing pipe can be exposed to the outside through the bottom. In this case, the washing water output from the first nozzle moves the defecation and urination in a front direction on the bottom plate 2902, and the washing water output from the second nozzle moves the defecation and urination to the side on the bottom plate 2902, and the moved defecation and urination can be discharged to the outside through a hole in the support part 2904 and a discharge pipe.

[0090] Meanwhile, the components of the above-described embodiments can be easily understood from a process perspective. That is, each component can be understood as a process. Furthermore, the processes of the above-described embodiments can be easily understood from the perspective of the components of the device.
