Description

  The present invention is a person who has difficulty in going to the toilet due to a physical disorder, etc., a so-called bedridden person who is difficult to operate such as raising a body in a hospital, a nursing facility or home, and cannot excrete excretion by himself The present invention relates to an excrement disposal apparatus suitable for use by a person or the like. More specifically, the present invention relates to an excrement disposal apparatus that can automatically and reliably excrete excrement even when the user excretes excretion while lying down.

  Conventionally, many related techniques of this kind have been proposed. A typical one is a diaper used to cover the lower back. In addition, recently, a type has been proposed in which a diaper cup is directly covered and surrounded by a diaper cup and a diaper cover is attached thereon. As an example of such a diaper cup, the diaper cup has a structure that can be elastically deformed so as to be in close contact with the body shape of the body, and the diaper cover that covers the diaper cup has a structure that can be easily replaced and has no risk of leakage. Known (see, for example, Patent Documents 1 and 2).

In particular, the diaper cup is attached in direct contact with the lumbar region, and is required to have a structure that does not leak excrement due to the nature of the purpose of use. For this reason, conventionally, the function of the diaper cup itself has been improved as well as the shape of the diaper cup itself. Ideally, the shape of the diaper cup itself is made to fit the individual body. However, even when it is not in the body, it is ideal that at least its functions can be handled under various usage conditions on the user side. For this reason, it has been conventionally known that a diaper cup body includes a cleaning device for cleaning excrement and a detection device for detecting the presence or absence of excrement (for example, patents). Reference 3). The excrement excreted in the diaper cup body is collected in an external filth tank or the like through the discharge port.
Japanese Patent No. 3077085 JP 2001-112804 A Japanese Patent No. 3766366

  As described above, various devices have been conventionally proposed. However, in terms of completely excreta disposal, there are still many problems and room for improvement. For example, in a device that improves the close contact with the lower back and prevents the diaper cup and diaper cover from leaking washing water and excrement, if the user changes his / her posture, etc. There is a possibility that leakage cannot be completely prevented. Further, diaper cups that are directly related to excrement may cause problems in terms of hygiene, environment, etc. unless the excrement is excreted and then washed immediately to maintain a clean state. In many of the current excrement disposal devices, a diaper cup body is attached with a cleaning device and a means for detecting the presence or absence of excrement. However, the current excrement disposal apparatus has not been sufficiently satisfied by the users, caregivers, nurses, caregivers, nurses, and the like.

  For example, even a bedridden person or the like is not always in the same posture, and the posture may be changed, for example, by changing the orientation of the body at about 45 degrees. Therefore, when using a diaper cup, the excrement in the diaper cup body must be surely and smoothly discharged regardless of the orientation of the person using the diaper cup. Don't be. That is, the excrement must be surely and smoothly discharged regardless of the state of the user changing the direction of the body.

  From this point of view, it is difficult to say that the current excrement disposal apparatus is always compatible with it. That is, current excrement disposal apparatuses often have a single jet of cleaning water (cleaning liquid), which may make it difficult to discharge excrement from the entire interior of the diaper cup body. Moreover, although there exist some which have a some jet nozzle, the jet direction of washing water is one direction, and the same problem arose. In addition, there are some that eject air from around the diaper cup, but the direction of this air blow is also directed to one point near the washing water outlet, and there is a risk that excrement cannot be discharged from the entire interior of the diaper cup body There is. In particular, if the user excretes excrement at a position where the posture is changed (for example, a position inclined 45 degrees), there is a problem that it may be difficult to discharge the excretion after excretion. .

  Furthermore, the detection means has a problem that the detection range is limited and the position where excrement can be detected is biased. In addition, there is a problem in that the presence or absence of the excrement may not be detected if the excrement is excreted when the user changes the posture such as changing the body orientation.

  That is, it is difficult to say that the excrement in the diaper cup body can be reliably detected or washed. Such a thing means that the excrement in the diaper cup body cannot be completely discharged and may be retained. This causes unpleasantness and unsanitary for the user, such as the generation of odor. In addition, caregivers, nurses, caregivers, and the like have problems such as an increased processing burden.

  Diaper cups are attached and removed by caregivers, nurses, caregivers and the like. For this reason, it is required that there be no leakage after the installation to the user or the like until the next replacement. Moreover, it is necessary to remove excrement completely from a diaper cup etc. Furthermore, the processing burden on caregivers, nurses, caregivers, etc. associated with the exchange of diaper cups, etc. must be reduced. In particular, caregivers, nurses, and caregivers can reduce the burden on caregivers, nurses, and caregivers if they can reduce the work of attaching and detaching at night. That is, a caregiver, a caregiver, etc. can go to bed at night like a normal person.

  The excrement disposal apparatus of the present invention solves such a conventional problem, and can be easily handled even at a medical site in a hospital, a nursing site at a nursing facility, a home nursing site at home, etc. Achieve the following objectives.

  The purpose of the present invention is to forcefully clean the bottom side of the diaper cup body, the inside of the side wall surface, and to be able to reliably detect the presence or absence of excrement inside the diaper cup body, the user, caregiver, An object of the present invention is to provide an excrement disposal apparatus that can reduce the burden on nurses and caregivers.

In the figure, the diaper cup body 1 itself, which is the main member of the present embodiment, has a known configuration. The basic configuration is described in detail in the aforementioned patent document and the like, and detailed description is omitted. However, in order to facilitate understanding of the present embodiment, an outline of the diaper cup body 1 will be described. The diaper cup main body 1 has a shape that directly surrounds and surrounds the vicinity of the excretory part including the genital part and anus of the body, and is generally formed of a resin body. The base portion of the diaper cup body 1 is made of a hard resin such as a polycarbonate resin.
The diaper cup body 1 has a recess 1a so that excretion excreted when the user is lying on his / her back is accumulated below the body. Moreover, although not shown in figure, the diaper cup main body 1 may be attached with attachment members, such as a belt, or may be attached so that it may be wrapped with a diaper cover body.

  A member such as a hose is attached to the end of one side (hereinafter referred to as the foot side) which is the foot side of the body of the diaper cup body 1. Although not shown in detail, the front cover 2 is attached to the front portion of the diaper cup body 1 as described above. The front cover 2 covers the vicinity of the shadow by deformation of the contact portion of the front cover 2 or the like. The front cover 2 is combined with the diaper cup main body 1 so that excrement does not leak from the inside of the diaper cup main body 1 and the front cover 2 and is in close contact with the body.

  Further, the diaper cup body 1 includes a genital washing nozzle 5 for ejecting a washing liquid for washing the pubic area or the vicinity of the pubic area, an anal washing nozzle 6 for ejecting a washing liquid for washing the anus or the vicinity of the anus, and a diaper cup. A cleaning nozzle body 7 for ejecting a cleaning liquid for cleaning the bottom surface of the main body 1 and the inner side of the side wall surface is provided (see FIG. 3). Moreover, the diaper cup main body 1 is provided with the detection means 8 for detecting the presence or absence of excrement, and the warm air outlet for blowing out warm air. This warm air dries the excretion part after washing the excretion part (pubic part, anus), the vicinity of the excretion part, the bottom surface of the diaper cup main body 1, the inner side of the side wall surface, and the like. Moreover, the excrement suction port 1b for excretion discharge | emission is provided in the edge part by the side of the leg part of the diaper cup main body 1. FIG. Further, the excrement suction port 1b is provided with a excretion suction hose 10 so as to be coupled to the excretion suction port 1b and project outside. In the vicinity of the excrement suction hose 10, a cleaning liquid supply hose (not shown), a detection means cable (not shown), and a blower hose (not shown) are provided. The excrement suction hose 10, the cleaning liquid supply hose, the detection means cable, and the blower hose are coupled to an external device (not shown). The diaper cup body 1 is configured as described above. When attaching the diaper cup main body 1 to the body, the diaper cup main body 1 is surrounded while being applied to the buttock side of the body, the genital cup side 1 is surrounded by the front cover 2, and the position is fixed.

  The peripheral part of the hollow 1a has a structure in which a step is provided, and the excrement excreted from the genital part and the anus can be prevented from leaking out of the diaper cup body 1. Moreover, the excrement suction hose 10 mentioned above is connected to the excretion suction port 1b located in the leg part side of this hollow 1a part. Even when the user is lying on his / her back, the excrement is received in the recess 1a, immediately guided to the excretion suction port 1b, and sucked and discharged through the excretion suction hose 10. The excrement suction hose 10 or the like is configured such that the depression 1a is positioned below the body when the user is in a normal lying position and lying down.

  The excrement is sucked and discharged through the excretion suction hose 10 together with the cleaning liquid that has been cleaned by a vacuum pump or the like, and collected in a separate waste tank (not shown). In the present embodiment, water or a mixed liquid of water and air is used as the cleaning liquid. The cleaning liquid may be a liquid having a deodorizing function, a deodorizing function, a sterilizing function, or the like, or a liquid in which a predetermined amount of a mixture is mixed. However, these liquids are limited to liquids that do not cause any trouble or adverse effect on the user. A cleaning liquid supply hose for supplying the cleaning liquid is provided at the foot side portion. The supplied cleaning liquid is guided to the diaper cup body 1 and then branched and supplied to the pubic cleaning nozzle 5, the anal cleaning nozzle 6, and the cleaning nozzle body 7.

  This cleaning liquid is fed from a separate cleaning liquid tank (not shown) installed outside. The cleaning liquid is, for example, a warm liquid mixture of warm water and air. The cleaning liquid guided to the genital region washing nozzle 5 mainly cleans the genital region of the body excretion region and the genital region. The cleaning liquid guided to the anus cleaning nozzle 6 mainly cleans the anus and the anus periphery of the excretory part. The anal cleaning nozzle 6 and the genital cleaning nozzle 5 are each provided at a position close to the site to be cleaned. Moreover, a ventilation hose is for sending warm air etc., and sends warm air in the diaper cup main body 1 from a warm air jet nozzle. This warm air dries the excretion part and the vicinity of the excretion part.

  The cleaning nozzle body 7 is provided on the other side which is the head side of the body of the diaper cup body 1 (hereinafter referred to as the head side). As shown in the rear view of FIG. 8, the cleaning nozzle body 7 has a semicircular shape along the seating surface, and is provided with a plurality of partition portions 7 a whose angles are changed on the rear surface side. The partition portion 7a has a guiding function of dispersing the supplied cleaning liquid over the bottom surface of the diaper cup body 1, the inner side of the side wall surface (hereinafter referred to as the inner wall surface of the diaper cup body 1), and the like. Further, the diaper cup body 1 is formed with a guide groove 1c serving as a cleaning liquid channel shown in FIG.

  The upper end 1d on the head side of the guide groove 1c is in a closed state. The guide groove 1c is provided with a first discharge port 1e and a second discharge port 1f for discharging the cleaning liquid to the front side (inner wall surface side) up to the upper end 1d. Accordingly, the cleaning liquid guided to the guide groove 1c is forcibly ejected to the front side via the first discharge port 1e and the second discharge port 1f. The first discharge port 1e is formed in the vicinity of the upper end 1d and at a position slightly away from the supply port side (foot side). The second discharge port 1f is formed at a position away from the first discharge port 1e by a predetermined amount toward the supply port. The guide groove 1c shown in the figure is shown in an open state, but actually, the entire guide groove is covered with a cover 1g and sealed.

  Therefore, the guide groove 1c is a flow path for the cleaning liquid in a sealed state, and is a pair of guide grooves 1c branched in the left and right directions. The cleaning liquid is guided to the diaper cup body 1 from an external cleaning liquid tank, and then, as indicated by an arrow, a pair of guides branched in two directions from the supply port provided in the foot side portion of the diaper cup body 1 It flows in the groove 1c and is guided to the cleaning nozzle body 7 provided on the head side (see FIG. 5). The flow path for the cleaning liquid may be configured to attach the pipe to the diaper cup body 1 as a flow path body in addition to the structure in which the guide groove 1 c is provided as a part of the diaper cup body 1. The guide groove may be configured such that the back surface is constituted by one flow path and branches into a pair of first discharge port 1e and second discharge port 1f at the top. Since the guide groove and the pipe are attached to the back side of the diaper cup main body 1, there is no concern about the appearance, and no interference or trouble occurs when the diaper cup is attached to the body.

  As shown in FIG. 2, a cleaning nozzle body 7 is attached to the diaper cup body 1 on the front side (inner wall surface side) in the vicinity of the first discharge port 1e and the second discharge port 1f. The cleaning liquid guided along the guide groove 1 c is discharged from the first discharge port 1 e and the second discharge port 1 f and is guided to the cleaning nozzle body 7. In the present embodiment, the first discharge port 1e and the second discharge port 1f are respectively provided on the left and right sides to form a pair. The cleaning liquid guided to the head side of the guide groove 1c is discharged from the first discharge port 1e and the second discharge port 1f to the back surface space portion 7b on the head side of the cleaning nozzle body 7. The cleaning liquid discharged from the first discharge port 1e mainly flows in the direction from the head side to the foot side (arrow P direction), and cleans the central portion of the inner wall surface of the diaper cup body 1 (FIG. 2). , 8).

  Further, the cleaning liquid discharged from the second discharge port 1 f flows in the direction of arrow Q by the partition portion 7 a of the cleaning nozzle body 7. More specifically, as shown in FIG. 8, the cleaning liquid guided to the guide groove 1c is discharged from the first discharge port 1e and the second discharge port 1f on the diaper cup body 1 side. The discharged cleaning liquid is guided from the first discharge port 1e and the second discharge port 1f to the back surface space portion 7b on the cleaning nozzle body 7 side. The cleaning liquid in the back surface space portion 7b comes into contact with the side wall of the cleaning nozzle body 7 and forcibly changes its direction at the partition portion 7a. Further, the cleaning liquid is guided along the inclined surface of the partition portion 7 a and is ejected from the cleaning nozzle body 7 into the diaper cup body 1. It is preferable that the space | interval dimension h of the jet nozzle front-end | tip part of the nozzle body 7 for washing | cleaning and the diaper cup main body 1 is about 0.5-1 mm, for example (refer FIG. 9). Thus, by narrowing the dimensions, the jetting pressure of the cleaning liquid jetted from the jetting port can be increased. The cleaning liquid ejected from the ejection port flows out along the inner wall surface of the diaper cup body 1.

  The ejection direction of the cleaning liquid whose direction is changed by the partition portion 7a is the arrow Q direction shown in FIGS. The partition portion 7 a is also provided at the end of the cleaning nozzle body 7. By having the partition part 7a at this end, the cleaning liquid is jetted onto the inner wall surface (bottom surface) of the bottom of the diaper cup body 1 and the inner wall surface (side wall surface) of the side portion. That is, the cleaning liquid can be ejected over substantially the entire width of the inner wall surface. It is preferable that the amount of the cleaning liquid flowing in the direction of arrow P is larger than the amount of the cleaning liquid flowing in the direction of arrow Q. In other words, the flow of the cleaning liquid flowing in the direction of arrow P is the main flow (for example, a flow of 40% of the total flow rate), and the flow of two cleaning liquids flowing in the direction of arrow Q is a tributary (for example, a flow of 30% of the total flow rate). ). The tributary flowing in the direction of arrow Q acts to push the excrement on the inner side of the side wall surface and the bottom surface to the main flow side. The excrement pushed away to the main stream side is pushed away along the main stream and sucked and discharged from the excrement suction port 1b through the excrement suction hose 10.

  A first detection member 14 to be described later is provided on the outer side of the side wall surface of the diaper cup body 1. Since the cleaning liquid also flows in the direction of the arrow Q on the inner wall surface of the diaper cup body 1 corresponding to the mounting position of the first detection member 14, the cleaning can be performed. That is, since excrement is cleaned even if it tries to adhere to the inner wall surface corresponding to this attachment position, the performance of excrement detection of the first detection member 14 is not deteriorated.

  The partition portion 7a forms a plurality of walls having an angle from the head side to the foot portion side. As shown in the figure, the cleaning liquid discharged from the lower hole is forcibly dispersed and flows along the partition portion 7a over almost the entire width of the inner wall surface of the diaper cup body 1. Therefore, even if the user wearing the diaper cup body 1 changes the posture by changing the direction of the body, it can be forcibly cleaned. Moreover, the excretion excreted from the excretion part can be forcibly washed at any position on the inner wall surface of the diaper cup body 1. Thereby, generation | occurrence | production of the situation which remains on the inner wall face of the diaper cup main body 1 without excretion being discharged | emitted can be prevented. In addition, the partition portion 7a allows the cleaning liquid to flow also to a terminal portion of a detection terminal portion of the second detection means 15 described later. In other words, the cleaning liquid cleans the terminal portion of the second detection means 15 and the vicinity of the terminal portion.

  Next, the detection relationship will be described. The detection means 8 is mainly composed of a first detection member 14 for stool for detecting the presence / absence of stool excretion, and a second detection member 15 for urine mainly for detecting the presence / absence of urine excretion. Yes. The 1st detection member 14 is provided ranging over the direction which crosses the moving direction of the excretion excreted from an excretion part (refer to Drawings 2 and 3). That is, the first detection member 14 is a transmissive optical sensor provided on the outer side of both side wall surfaces of the diaper cup body 1, and a sensor using infrared light is suitable. In this embodiment, the first detection member 14 will be described as a transmissive infrared sensor. The first detection member 14 includes one detection body 14a including a first light emitter and a first light receiver, and the other detection body 14b including a second light receiver and a second light emitter. Is due to.

  For example, the first light emitter and the second light receiver, and the first light receiver and the second light emitter face each other and make a pair. One detection body 14a and the other detection body 14b are provided opposite to each other on the outer side of the side wall surface of the diaper cup body 1. Thus, by providing the 1st detection member 14 in the exterior side of the side wall surface of the diaper cup main body 1, it prevents that 1st detection member 14 itself gets dirty. The infrared light used in the first detection member 14 can pass through the side wall surface of the diaper cup body 1.

  When the excrement passes, the first detection member 14 detects the passage of the excretion based on whether or not the projected infrared light is received and confirms the excretion without contact. Infrared light is always projected from the light emitter to the light receiver, and when the excrement passes, the infrared light path is temporarily blocked. The presence or absence of stool, which is excretion, is confirmed by detecting the blocking state with a photoreceptor. A plurality of light emitters and light receivers are provided, and a plurality of light fluxes are provided so as to have a predetermined width in a direction crossing the excrement moving direction. In addition, one detection body 14a and the other detection body 14b are attached to be inclined at a predetermined angle (see FIG. 3). Thereby, even if the diaper cup main body 1 has a concave complicated shape, and the diaper cup main body 1 is inclined, it is possible to detect the presence or absence of excrement. Furthermore, by setting it as such a structure, it sticks to the inner wall surface (a bottom face, the inner side of a side wall surface) of the diaper cup main body 1 like the soft stool often seen by the user who uses such an excrement disposal apparatus. Even such stool can be detected reliably.

  Therefore, even if the amount of excrement is small, if excrement moves and passes through this detection region, the passage of excrement can be captured and detected without fail. The first detection member 14 is disposed at a position on the head side outside the side wall surface of the diaper cup body 1.

  For example, when the user is lying on his / her back, excrement hardly stains the inner wall surface corresponding to the first detection member 14. However, when the user is in a state of sleeping while changing the body direction (for example, a state inclined at 45 degrees), the inside of the diaper cup body 1 to which the first detection member 14 is attached is temporarily. The wall surface may be contaminated by excreted excreta. However, in such a case, as described above, the cleaning liquid ejected through the partition portion 7a on the end side of the cleaning nozzle body 7 forcibly cleans the inner wall surface corresponding to the mounting position of the first detection member 14. Can do.

  The detection terminal portion of the second detection member 15 is intended for urine excrement. Piss accumulates between the pair of detection terminal portions. The resistance value between the detection terminal portions changes in a state where there is no water between the detection terminal portions, a state where cleaning liquid, water is accumulated, and a state where water containing salt is accumulated. The urine corresponds to water containing salt. When a predetermined amount (for example, 15 ml) of water containing salt is accumulated, it is detected that urine is excreted. That is, urine is, for example, water containing salt, and since the resistance value of salt water is smaller than that of mere water (for example, tap water), it is detected that the resistance value is reached. ing. In other words, even if water is accumulated, the resistance value is higher than that in the case where water containing salt is accumulated, so that discrimination is possible. That is, it is avoided that the cleaning liquid is ejected in a state where water other than urine (for example, the cleaning liquid) is accumulated. In addition, when a certain amount of salt-containing water has accumulated, it is possible to detect when a small amount of urine is excreted (for example, when a small amount of urine is leaked). I try not to. As shown in FIG. 2, the pair of detection terminal portions of the second detection member 15 are provided at three positions on the bottom surface of the diaper cup body 1.

  That is, a pair of detection terminal portions 15a and 15b are provided on the bottom surface on the head side on the left and right, respectively. Further, a pair of detection terminal portions 15c are provided in the center on the bottom surface on the foot side. The pair of detection terminal portions 15a to 15c are all located below the body when the user is lying on his / her back. Therefore, in the posture of lying on the back, whenever the urine s is excreted, it always flows downward and accumulates in the depression 1a, so that it can be reliably detected by the pair of detection terminal portions 15c (see FIG. 7).

  For example, in a state where the user is sleeping with his body turned, the urine s and the like can be detected by either the pair of detection terminal portions 15a or the pair of detection terminal portions 15b (see FIG. 6). It has become. The urine is water containing salt. In order to reliably detect the presence or absence of urine, a detection member that detects the presence or absence of water containing salt is suitable. The second detection member 15 is configured such that the terminal portions at the tips of the pair of detection terminal portions 15 a to 15 c are exposed on the front side (inner wall surface side) of the diaper cup body 1. As shown in the figure, the connecting portion with the diaper cup main body 1 is sealed on the back side of the diaper cup main body 1 (the bottom surface, the outside of the side wall surface) so as to prevent filth, waste liquid, and the like including excrement from leaking. . Each of the pair of detection terminal portions 15a to 15c is provided with a wiring 15d. The wiring on the back side is connected to connecting means on the foot side portion of the diaper cup body 1 and is connected to an external control device (not shown) via a cable. Then, the presence or absence of urine excretion is determined in the control device. Moreover, this diaper cup main body 1 is good to be the structure by which the back surface side wiring space is covered with the cover 1h with the above-mentioned guide groove 1c (refer FIG. 4).

  Excrement in the diaper cup body 1 having such a configuration is detected by the first detection means 14 for stool and the second detection means 15 for urine. When it is detected that there is excrement in the diaper cup body 1, the cleaning liquid is fed from the cleaning liquid hose, and is distributed and fed to the genital cleaning nozzle 5, anal cleaning nozzle 6, and cleaning nozzle body 7. The pubic area, the genital area, the anus, the anus area, the inner wall surface of the diaper cup body 1 and the like are washed. Further, the vacuum pump is operated, and the waste water containing the waste is forcibly sucked and discharged from the diaper cup body 1 through the waste suction hose 10 and collected in a waste tank (not shown).

For example, when fecal excretion is detected by the first detection means 14, the cleaning liquid, which is a mixture of water and air, flows from the anal cleaning nozzle 6 and the cleaning nozzle body 7 to the anus, the anus, and the diaper cup body 1. Clean the inner wall surface. Even if fecal excretion is detected, the cleaning liquid may be ejected from the genital washing nozzle 5 to wash the genital area and the genital area.
When urine excretion is detected by the second detection means 15, the cleaning liquid, which is water, cleans the genital area, the genital area, the inner wall surface of the diaper cup body 1, etc. from the genital area cleaning nozzle 5 and the rinsing nozzle body 7. To do. Such switching of the cleaning liquid can be performed by controlling a direction switching valve provided in the water and air supply circuit with a control device (not shown).

  Further, cleaning at the time of excretion of stool and cleaning at the time of excretion of urine may be performed with a cleaning liquid that is a mixture of water and air. In that case, it is preferable to change the amount of the cleaning liquid during stool excretion and urine excretion. For example, the amount of cleaning liquid ejected once may be a predetermined amount, and the cleaning liquid may be ejected in a plurality of times, and the number of times may be controlled. For example, it is good to make it eject 7 times at the time of excretion of stool and to eject 3 times at the time of excretion of urine.

  When stool excretion is detected, air is mixed with water, and a cleaning liquid that is a pressure liquid whose pressure is increased may be ejected. When the cleaning liquid with increased pressure liquid is ejected, the inner wall surface of the diaper cup body 1 can be easily and reliably cleaned. Moreover, even if it is a loose stool often seen by the user who uses such an excrement disposal apparatus and sticks to the inner wall surface of the diaper cup main body 1, it is discharged | emitted from the diaper cup main body 1 so that it may be forcedly washed away. it can. The washing liquid that has washed the anus, the genital area, the inner wall surface of the diaper cup main body 1 and the like becomes filth containing excrement, and is sucked and discharged from the diaper cup main body 1 through the excrement suction hose 10.

  The diaper cup main body 1 maintains a state of being in close contact with the body even if the user changes the direction of the body or the like during sleeping. Every time a user excretes excrement, the presence or absence of excrement is automatically detected, and filth containing excrement is always sucked and discharged from the diaper cup body 1. Although not shown, the diaper cup body 1 configured in this manner is preferably covered with a diaper cover body made of a soft synthetic resin, a diaper cover body that is a disposable paper diaper, or the like. Even if filth containing excrement leaks from the diaper cup body 1, the diaper cover body can prevent the filth containing excrement from leaking outside the diaper cover body.

  The amount of excrement and the number of suctions vary depending on the user. However, in any case, during the sleeping time, filth containing excrement is prevented from leaking outside, and excrement can be discharged reliably. Further, as described above, in any state, filth including excrement is prevented from leaking to the outside, and excrement can be discharged reliably. For this reason, caregivers, caregivers, nurses, etc. do not always have to accompany the user during this time period. That is, a caregiver and a caregiver can secure sleep time like a general person, and a nurse can perform other duties.

  The filth including the excreta discharged and discharged is collected and stored in a separate filth tank (not shown). This filth tank is provided along with other devices along with the diaper cup comprising the diaper cup body described above, and is placed in the vicinity of the user's bed. In addition to this waste tank, a device for feeding cleaning liquid to the cleaning liquid supply hose, a device for blowing air to the blower hose, a device for sucking waste containing excrement, a device for purifying air, and a detection means It is preferable that a control device or the like that electrically performs a control process in response to the detection signal is combined into a single device.

  As mentioned above, although embodiment of this invention was described, this invention is not limited to this embodiment. Needless to say, changes can be made without departing from the scope and spirit of the present invention.

  The present invention relates to a person who has a physical illness, injury, disability, etc., who has difficulty in going to the toilet, a person who has difficulty in moving or waking himself up, a person who cannot excrete excretion by himself, etc. The user can perform excrement disposal automatically and hygienically in a lying posture.
