Description

Specification

Waste disposal equipment

Technical field

[0001] The present invention relates to a person who has difficulty in going to the bathroom because of physical disability etc., a so-called bedridden person who has difficulty moving up in the hospital or nursing home, etc., and excrete excrete by himself. The present invention relates to an excrement disposal apparatus suitable for force use by persons who can not excrete. More particularly, the present invention relates to an excrement disposal apparatus capable of reliably and automatically excrementing excrement even when the user excretes excrement in a bed-like state.

Background art

[0002] Conventionally, many related technologies of this type have been proposed. Typical ones are used to cover the hips. Furthermore, in recent years, a type has also been proposed in which the hip cup is directly covered and surrounded with a cup, and a cover is attached on top of it. As an example of such a cup, the cup is adapted to be elastically deformable so as to be in close contact with the body shape of the body, and the cover covering the cup is known to have a structure that is easy to replace and has no risk of water leakage. (See, for example, Patent Documents 1 and 2).

[0003] In particular, the cup is attached to and directly attached to the lower back, and due to the nature of the purpose of use, adhesion is required and a structure having no leakage of excrement is required. For this reason, in the past, improvements have been made not only to the shape of the mug cup itself, but also to the functions of the mug cup itself. The shape and power of the mug cup itself It is ideal if it is made to fit the individual body. However, even if not in the body, at least its function should ideally be able to cope with various usage conditions on the side of use. From these facts, it has been conventionally known that a cleaning device for cleaning excrement and a detection device power S for detecting the presence or absence of excrement are provided in the body cup (for example, Patent Document 3). The excrement excreted in the main body of the mug cup is collected in the external waste tank etc via the discharge port.

Disclosure of the invention

Problem that invention tries to solve

[0004] As described above, conventionally, various devices have been proposed. However, there are still many problems and there is room for improvement in terms of complete waste treatment. For example, in a device that improves adhesion to the lower back and prevents leakage of wash water and excrement from the surroundings of the cup and the cover, if the user changes the posture, the posture is completely changed. There is a possibility that the leak can not be prevented. In addition, the cups directly related to excrement could cause problems in terms of hygiene, environment, etc. unless they are cleaned immediately after excreting excrement and always maintain a clean condition. Many of the present waste disposal systems are equipped with a washing device and a means for detecting the presence or absence of excrement on the main cup. However, the present excrement disposal devices were not sufficient for the people, carers, nurses, assistants, nurses, etc., who are using them.

[0005] For example, even a bedridden person or the like may not always be in the same posture, for example, may change the posture such as changing the direction of the body by about 45 degrees. Therefore, when using a cup, it is necessary to ensure that the excrement in the cup cup is discharged smoothly, regardless of the posture of the person who is using it within a predetermined range. . That is, regardless of the user's physical orientation or whatever, the excrement must be discharged smoothly and reliably.

From this point of view, the present excrement disposal apparatus has a point that can not be said to correspond! That is, in the present excrement disposal apparatus, it may be difficult to discharge the excrement from the entire inside of the main body of the cup that the spout of the washing water (washing liquid) is too large. In addition, in some cases having a plurality of jets, the direction of the force of washing water was one direction, and the same problem occurred. Furthermore, there is also a force that ejects air from the periphery of the cup, and the direction of the air jet is also directed to a point near the flush water jet, and there is a risk that excrement can not be discharged from the entire inside of the cup cup. . In particular, the user excretes at a position where the posture is changed (for example, a position inclined 45 degrees) There was a problem that it would be difficult to excrete excrement after excretion if excreted.

Furthermore, the detection means also has a problem that the detection range is limited and the position where the excrement can be detected is biased. In addition, there is a problem that the presence of excrement can not be detected if excrement is excreted while the person who uses it changes posture such as changing the direction of the body! ! /.

[0008] That is, there is an aspect that can not be said as a configuration that can reliably detect or clean the excrement inside the cup cup body. Such a thing means that there is a possibility that the waste in the main body of the cup can not be completely drained, and can be retained. This causes discomfort to the user, such as the generation of odor, and is unsanitary. In addition, caregivers, nurses, assistants, etc. have problems such as increased processing burden.

[0009] A cup, etc. is attached by a carer, a nurse, a carer, etc. and removed. Therefore, it is required that there be no leak completely between the installation to the user etc. and the next time the installation and replacement are carried out. In addition, excrement should be completely removed from the cup and so on. Furthermore, the processing burden of carers, nurses, assistants, etc., associated with the exchange of cups etc., should be lightened. In particular, the burden on carers, nurses and carers can be greatly reduced if the work of carers, nurses and carers can be reduced at night. That is, carers and assistants can go to bed at night as well as ordinary people.

The excrement disposal apparatus of the present invention solves such conventional problems, and it is possible to use the medical care site in a hospital, the care site in a care facility, the home care site at home, etc. Achieve the following objectives as easily handled.

[0011] The object of the present invention is to make it possible to forcibly clean the bottom and side walls of the cup cup forcibly and to detect the presence or absence of excrement inside the cup cup, and the user, An object of the present invention is to provide an excrement disposal device capable of reducing the burden on caregivers, nurses, and assistants.

[0030] In the drawings, the main cup 1 itself, which is the main member of the present embodiment, has a known configuration. The basic configuration is described in detail in the above-mentioned patent documents and the like, and the detailed description is omitted. However, in order to facilitate understanding of the present embodiment, an outline of the main cup 1 will be described. The mug cup body 1 is in close contact with and surrounded by the vicinity of the excretory part including the pubic part and the anus of the body, and is generally made of a resin body.

. The base portion of the cup cup body 1 is made of, for example, a hard resin such as polycarbonate resin.

The mug cup main body 1 forms a recess la so that excrement excreted when the user is lying on the back is accumulated under the body. Also, although not shown, the main cup 1 may be mounted using a mounting member such as a belt, or may be mounted so as to be wrapped in a main cover.

[0031] A member such as a hose is attached to the end of one side (hereinafter referred to as the foot side and the foot side) of the foot side of the body of the cup cup body 1. Further, as described above, the front cover 2 can be attached to the front of the main cup 1 as described above. The front cover 2 covers the vicinity of the shade by deformation or the like of the contact portion of the front cover 2. The front cover 2 is combined with the main cup body 1 so that excrement can be closely enclosed to the body so as not to leak from the inside of the main body 1 and the front cover 2 to the outside.

Furthermore, a nozzle for pelvic part cleaning 5 for spouting a cleaning liquid for cleaning the genital region or the vicinity of the genital region, and an anus lavage nozzle for spouting a cleaning liquid for cleaning the anus or the anus region 6, Clean the bottom of the cup cup 1 and the inside of the side wall surface There is a cleaning nozzle body 7 for spouting the cleaning solution (see Figure 3). In addition, the mug cup body 1 is provided with detection means 8 for detecting the presence or absence of excrement, and a hot air outlet for blowing hot air. This warm air dries the excretory part after cleaning of the excretory part (the negative part, the anus), the vicinity of the excretory part, the bottom of the moch cup main body 1, the inner side of the side wall surface, and the like. In addition, at the foot side end of the main cup 1, an excrement suction port lb for excrement is provided. Further, the waste suction port lb is provided with a waste suction hose 10 so as to be coupled to the waste suction port lb and to be protruded outside. In the vicinity of the waste material suction hose 10, a cleaning solution supply hose (not shown), a detection means cap (not shown), and a blowing hose (not shown) are provided. The waste suction hose 10, the washing liquid supply hose, the cable for the detection means, and the blower hose are connected to an external device (not shown). The cup cup body 1 is configured as described above. To attach the cup cup body 1 to the body, place the cup cup body 1 against the buttocks side of the body, surround it with the front cover 2, and fix it when the position is fixed.

The peripheral portion of the recess la is provided with a step, and has a structure capable of preventing leakage to the outside of the excrement excrement cup body 1 excreted from the genital region and the anus. Further, the excrement suction hose 10 described above is connected to the excrement suction port lb located on the foot side of the hollow portion la. Even when the user lies in a reclining position, the excrement is received by the recess la, immediately led to the excrement suction port lb, and aspirated and discharged through the excrement suction hose 10. Ru. In these excrement suction hoses 10 and the like, the depression la is positioned below the body when the user is in the normal posture of lying up and lying down.

The excrement is sucked and discharged by the vacuum pump or the like through the excrement suction hose 10 together with the cleaning liquid that has been cleaned, and is collected in a separate waste tank (not shown). In the present embodiment, water or a mixed solution of water and air is used as the cleaning liquid. In addition, 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 those that do not pose a risk of causing injury or adverse effects to the user. Cleaning solution for supplying cleaning solution A supply hose is provided at the foot portion. The supplied cleaning liquid is led to the main cup 1 and branched to be divided and supplied to the nozzle for head cleaning 5, the nozzle for anal cleaning 6, and the nozzle body for cleaning 7.

The cleaning solution is supplied from an externally installed cleaning solution tank (not shown). The cleaning solution is, for example, a mixture of warm water and air. The cleaning liquid guided to the genital region washing nozzle 5 mainly cleans the genital region and the periphery of the genital region of the excretory part of the body. The cleaning liquid guided to the anal cleansing nozzle 6 mainly cleanses the anus and the area around the anus of the excretory part. The anal lavage nozzle 6 and the genital lavage nozzle 5 are each provided at a position close to the site to be cleaned. Further, the blowing hose is for feeding warm air or the like, and sends the warm air into the hot air blowout cup cup body 1. The warm air dries the excretory part and the area around the excretory part.

The nozzle body 7 for cleaning is provided on the other side (hereinafter referred to as the head side) which is the head side of the body of the hood cup 1. As shown in the reverse view of FIG. 8, this cleaning nozzle body 7 has a semicircular shape along the seat surface, and is provided with a plurality of partition portions 7a whose angle is changed on the reverse side. . The partition 7a has a guiding function of dispersing the supplied cleaning liquid over the bottom surface of the cup body 1, the inner side of the side wall (hereinafter referred to as the inner wall surface of the cup body 1), and the like. Further, on the back surface side of the main cup body 1, a guide groove lc which is a flow path for the cleaning liquid shown in FIG. 5 is formed.

An upper end portion Id of the head side of the guide groove lc is in a closed state. The guide groove lc is provided with a first discharge port le and a second discharge port If for discharging the cleaning liquid to the front side (inner wall surface side) up to the upper end portion Id. Therefore, the cleaning liquid guided to the guide groove lc is configured to be forcibly ejected to the front side through the first discharge port le and the second discharge port If. The first discharge port le is formed in the vicinity of the upper end Id and at a position slightly separated from the supply port side (foot side). The second discharge port If is formed at a position separated by a predetermined amount from the first discharge port le toward the supply port. The guide groove lc in the figure is shown in an open state, but in fact, the entire guide groove is covered and sealed with a cover lg.

Therefore, the guide groove lc is a flow path for the cleaning liquid in a sealed state, and is a pair of guide grooves lc branched in the left and right directions. Cleaning solution is removed from the external solution tank After being guided to the cup body 1, as shown by the arrows, it flows in the pair of guide grooves lc branched in two directions from the supply port provided at the foot side portion of the cup cup body 1 to the head side. It is led to the provided cleaning nozzle body 7 (see Fig. 5). The flow channel for the cleaning liquid may be configured to attach a pipe as a flow channel body to the cup cup body 1, in addition to the configuration in which the guide groove lc is provided as a part of the cup cup body 1. The guide groove may be configured such that the back surface is formed by one flow path, and the upper portion is branched into a pair of first discharge ports le and a second discharge port If. Since the guide groove and the pipe are attached to the back side of the main cup 1, there is no interference or hindrance when mounting the main cup on the body which is not a concern for the appearance.

As shown in FIG. 2, the nozzle body 7 for cleaning is attached to the front side (inner wall surface side) of the first cup le and the second jet If if the cup cup body 1 is provided. The cleaning liquid guided along the guide groove lc is discharged from the first discharge port le and the second discharge port If, and is guided to the cleaning nozzle body 7. In the present embodiment, the first discharge port le and the second discharge port If are provided in pairs, one for each of the left and right sides. The cleaning liquid guided to the head side of the guide groove lc is discharged from the first discharge port le and the second discharge port If to the back surface space 7b on the head side of the nozzle body 7 for cleaning. The cleaning liquid discharged from the first discharge port le mainly flows from the head side toward the foot side (arrow P direction), and cleans the central portion and the like of the inner wall surface of the cup 1 (FIG. 2) , 8).

Further, the cleaning liquid discharged from the second discharge port If flows in the arrow Q direction by the partition 7 a of the cleaning nozzle body 7. More specifically, as shown in FIG. 8, the cleaning liquid guided to the guide groove lc is discharged from the first discharge port le and the second discharge port If on the side of the main cup 1. The discharged cleaning liquid is guided from the first discharge port le and the second discharge port If to the back surface space 7b on the cleaning nozzle body 7 side. The cleaning liquid in the back space 7b abuts on the side wall of the cleaning nozzle body 7 and is forcibly changed in direction by the partition 7a. Furthermore, the cleaning liquid is guided along the inclined surface of the partition 7 a and spouts out of the cleaning cup body 1 from the cleaning nozzle body 7. It is preferable that the distance dimension h of the tip of the jet nozzle between the cleaning nozzle body 7 and the main cup body 1 be, for example, about 0.5 to 1 mm (see FIG. 9). As described above, by reducing the size, it is possible to increase the ejection pressure of the cleaning liquid ejected from the ejection port. In addition, it spouted from the spout The cleaning solution is made to flow out along the inner wall surface of the cup 1.

The ejection direction of the cleaning liquid whose direction is changed by the partition 7a is the direction of the arrow Q shown in FIGS. The partition 7 a is also provided at the end of the cleaning nozzle body 7. By having the partition portion 7a at this end, the cleaning solution is jetted to the inner wall surface (bottom surface) and the inner wall surface (side wall surface) of the bottom portion of the cup cup body 1. In other words, it is possible to spout the cleaning solution S over substantially the entire width of the inner wall surface. The amount of cleaning solution flowing in the direction of arrow P is preferably larger than the amount of cleaning solution flowing in the direction of arrow Q. In other words, the cleaning fluid flow in the arrow P direction is the main flow (for example, 40% of the total flow), and the two cleaning fluid flows in the arrow Q direction are the tributaries (for example, 30% of the total flow, respectively) Like). The tributaries that flow in the direction of arrow Q have the function of pushing out the excrement on the inner side of the side wall surface and the bottom to the main stream side. The waste discharged to the main flow side is washed away from the main flow and sucked and discharged from the waste suction port lb through the waste suction hose 10.

A first detection member 14 described later is provided on the outer side of the side wall surface of the cup cup body 1. The cleaning liquid also flows in the direction of the arrow Q on the inner wall surface of the cup cup 1 corresponding to the mounting position of the first detection member 14 so that cleaning is possible. That is, since the excrement is cleaned as it adheres to the inner wall surface corresponding to the attachment position, the performance of the excrement detection of the first detection member 14 is not deteriorated.

[0043] The partition 7a comprises a plurality of walls each having an angle along the foot side from the head side. As shown in the figure, the cleaning liquid discharged from the lower hole is forcibly dispersed and flows along the entire width of the inner wall surface of the cushion body 1 along the partition 7a. Therefore, even when the user wearing the diaper cup body 1 changes the posture by, for example, changing the direction of the body, the user can forcibly wash it. In addition, the excrement excreted from the excrement part can be forcibly cleaned at any position on the inner wall surface of the cup cup 1. As a result, it is possible to prevent the occurrence of a situation where the excrement can not be discharged and remains on the inner wall surface of the cup 1. Further, the cleaning liquid also flows to the terminal portion of the detection terminal portion of the second detection means 15 described later by the partition portion 7a. 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 detecting means 8 mainly includes a first detecting member 14 for detecting the presence or absence of stool, and a second detecting member 15 for detecting the presence or absence of urine mainly. ing. The first detection member 14 is provided across the moving direction of the excrement excreted from the excrement part (see FIGS. 2 and 3). That is, the first detection member 14 is a transmission type optical sensor provided on the outer side of the side wall surface of both the main cup 1 and a sensor using infrared light is preferable. In this embodiment, the first detection member 14 will be described as a transmission type 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 receptor and a second light emitter. It depends on the configuration.

For example, the first light emitter and the second light receiver, and the first light receiver and the second light emitter are arranged to face each other in pairs. One detection body 14 a and the other detection body 14 b are provided opposite to each other on the outer side of the side wall surface of the cup cup body 1. Thus, by providing the first detection member 14 on the outer side of the side wall surface of the cup body 1, the first detection member 14 itself is prevented from becoming dirty. Further, infrared light used in the first detection member 14 can be transmitted through the side wall surface of the main cup body 1.

The first detection member 14 detects the passage of excrement through the presence or absence of the light reception of the projected infrared light when the passage of the excrement passes, and confirms without contact that the excrement is excreted. Infrared light is always projected from the light emitter to the light receiver, and when the excrement passes through, it temporarily blocks the infrared light path. By detecting the blocking state with a light receiver, the presence or absence of stool which is excrement is confirmed. 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 transverse to the moving direction of the excrement. Also, one detector 14a and the other detector 14b are attached with a force S at a predetermined angle (see FIG. 3). This enables detection of the presence or absence of excrement even when the main cup 1 has a complicated concave shape and the main body 1 is inclined. Furthermore, by adopting such a configuration, the inner wall surface (bottom side, inner side of the side wall surface) of the cup cup 1 may be clinged on like the soft stool often found by users using such waste disposal devices. It can be detected reliably even in

Therefore, even if the amount of excrement is small, excrement moves and passes through this detection area. If it does, it will always be able to capture and detect the passage of waste. The first detection member 14 is disposed at a position on the head side on the outer side of the side wall surface of the main body 1! /.

For example, when the user is lying on his back, excrement hardly contaminate the inner wall surface corresponding to the first detection member 14. However, when the user is in a sleeping state (for example, in a 45-degree inclined state) when the user turns his / her body, temporarily, the inner wall surface of the main cup 1 attached to the first detection member 14. Force S: There is a risk of getting dirty by excreted excrement. In such a case, as described above, the cleaning liquid force spouted through the partition 7a on the end side of the cleaning nozzle 7 forcibly cleans the inner wall surface corresponding to the mounting position of the first detection member 14 as described above. be able to.

The detection terminal portion of the second detection member 15 is intended for excrement of urine. Pimples collect between the pair of detection terminals. The resistance between the detection terminals changes in a state where there is no water between the detection terminals, in a state in which the cleaning liquid and water are accumulated, and in a state where water containing salt is accumulated. Urine corresponds to water containing salt, and when water containing salt is accumulated in a predetermined amount (for example, 15 ml), it is detected that urine is excreted. That is, urine is, for example, water containing salt, and since water containing salt has a smaller resistance than pure water (for example, tap water), it is detected that this resistance has been reached. I have to. In other words, even if water is stored, the resistance value is higher than when water containing salt is stored, so discrimination is possible. That is, it is avoided that the cleaning solution is spouted in a state where water other than urine (for example, the cleaning solution) is accumulated. In addition, when water containing a certain amount of salt is accumulated, detection is possible, and excretion of a small amount of urine (for example, a state where a small amount of urine such as a lip is leaked) is detected as the presence of urine being detected. I try not to. The pair of detection terminal portions of the second detection member 15 are, as shown in FIG. 2, distributed at three positions on the bottom surface of the cup cup body 1.

That is, on the bottom surface on the head side, a pair of detection terminal portions 15a and 15b are provided on the left and right, respectively. In addition, a pair of detection terminal portions 15c is provided at the center on the bottom surface of the foot portion. Each of the pair of detection terminal portions 15a to 15c is located below the body when the user is in the posture of lying on his back. Therefore, in the case of lying posture, when urine is excreted, it always flows downward and accumulates in the depression la, so a pair of detection terminal parts 15 It will be able to detect with c with certainty (see Figure 7).

For example, in the posture in which the user turns his / her body and sleeps, the configuration in which the urine s etc. can be detected by either the pair of detection terminal portions 15a or the pair of detection terminal portions 15b (FIG. 6) See). The urine is water containing salt, and in order to reliably detect the presence or absence of urine, a detection member for detecting the presence or absence of water containing salt is preferable. The second detection member 15 has a configuration in which the terminal portions at the ends of the pair of detection terminal portions 15a to 15c are exposed on the front side (inner wall surface side) of the diaper cup body 1. As shown in the figure, the joint with the main body 1 is sealed on the back side of the main body 1 (bottom side, outer side of the side wall surface) so that dirt including excrement and cleaning fluid do not leak. ing. A wire 15d is formed on each of the pair of detection terminal portions 15a to 15c. The wiring on the back side is connected to the connection means on the foot side portion of the cup body 1 and is connected to an external control device (not shown) via a cable. And, in the control device, it is determined whether or not urine is excreted. In addition, this camouflage cup body 1 is configured such that the wiring space on the back surface side is covered with the above-mentioned guide groove lc, and the entire back surface is covered with a force bar lh! / (See FIG. 4).

The presence or absence of the excrement in the body cup 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 an excrement in the main cup body 1, the cleaning fluid is sent from the cleaning fluid hose, dispersed and sent to the nozzle 5 for cleaning the genital area, the nozzle 6 for anal irrigation, and the nozzle body 7 for irrigation. Spray from the position, and wash the genitals, peri genital region, anus, perianus region, inner wall surface of main body 1 of om cup. Also, the vacuum pump is activated, and the waste water including excrement is forcibly sucked and discharged from the cup cup body 1 through the excrement suction hose 10, and collected in the waste tank (not shown).

For example, when stool excretion is detected by the first detection means 14, the cleaning liquid, which is a mixture of water and air, flows from the anus washing nozzle 6 and the washing nozzle body 7 to the anus, around the anus, and the pressure. Clean the inner wall etc. of the main body 1 It should be noted that, even when stool excretion is detected, the cleaning liquid may be jetted from the nozzle 5 for cleaning the negative part to clean the negative part and the periphery of the negative part. Is detected, the cleaning fluid, which is water, From the cleaning nozzle 5 and the cleaning nozzle body 7, the negative part, the area around the negative part, the inner wall surface of the cup cup body 1 and the like are cleaned. Such switching of the cleaning liquid can be performed by controlling the direction switching valve provided in the water and air supply circuit by means of a controller, not shown.

Furthermore, the cleansing for fecal excretion and the cleansing for fecal excretion may be performed with a cleansing solution which is a mixture of water and air. In that case, it is preferable to change the amount of cleaning fluid at the time of fecal excretion and fecal excretion. For example, it is preferable to control the number of times by setting the amount of the cleaning solution spouted at one time to be a predetermined amount and spouting the cleaning solution a plurality of times. For example, it is good to make it ejaculate seven times at the time of fecal excretion and three times at the time of urinal excretion.

When stool excretion is detected, it is preferable to mix air with water and spout the cleaning liquid as a pressure liquid with an increased pressure. By spouting the cleaning liquid with the pressure liquid raised, the inner wall surface of the cup 1 can be cleaned easily and reliably. In addition, even if it is a stool which is often found by users who use such waste disposal equipment and stools that cling to the inner wall surface of the cup cup 1, it is discharged from the cup cup body 1 so as to force it out. it can. The cleaning solution that has washed the anus, the pubic area, and the inner wall surface of the ucup cup body 1 becomes waste including excrement and is sucked and discharged from the ucup cup body 1 via the excrement suction hose 10

Even when the user turns his / her body during sleep, the body cup 1 is kept in close contact with the body even if the user performs an operation such as changing the direction of the body. Every time the user excretes excrement, the presence or absence of excrement is automatically detected, and the excrement including excrement is always sucked out of the main cup 1. Although not shown, it is preferable that the main body 1 configured in this way be covered with a cover made of soft synthetic resin, a cover made of disposable paper, or the like. Even if the waste containing the excrement leaks from the main body 1 of the mug, it is possible to prevent the leak of the waste including the excrement from the outside of the mug cover by the integration of the cover.

The amount of excrement, the number of times of suction, etc. differ depending on the user. However, in any case, at the time of bedtime, it is possible to prevent the waste including the excrement from leaking to the outside, and it is possible to reliably discharge the excrement. Also, as described above, regardless of the state, it is possible to prevent the waste including the excrement from leaking to the outside, and the excrement can be reliably discharged. this Therefore, it is not necessary for carers, assistants, nurses, etc. to always attend to users etc. at this time. In other words, carers and assistants can secure sleeping time the same way as ordinary people, and nurses can perform other tasks.

[0058] The filth including the sucked and discharged waste is collected and stored in a separate dirt tank (not shown). This waste tank, along with other devices, is provided in association with the above-described cup made of the above-described cup cup and the like, and is placed near the bed of the user. In addition to the filth tank, a device for feeding cleaning fluid to the cleaning fluid supply hose, a device for blowing air to the blowing hose, a device for sucking in the dirt including excrement, a device for purifying air, a detection means It is preferable that a control device or the like that receives control signals and perform control processes electrically is put together as a set into one device.

Although the embodiment of the present invention has been described above, the present invention is not limited to this embodiment. It goes without saying that changes can be made without departing from the object and the purpose of the present invention.
