Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention generally relates to an excrement absorber and a device for assisting urination, and particularly for the treatment of human waste including so-called bedridden elderly people, severely ill patients and patients who cannot move due to trauma such as bone fracture. A preferred excrement absorber and device.

[0002]

2. Description of the Related Art In recent years, the aging of the population in Japan is progressing at a rapid rate, and the population of elderly people, so-called bedridden elderly, is also rapidly increasing. In such a situation, when the elderly in the family become bedridden old people, it is common for someone in the family to take care of them. However, in general, care of bedridden elderly people is very heavy labor, unlike the care of infants.

[0003] Above all, disposing of human waste requires the caregiver to perform the most painful and unclean physical work. If the caregiver himself who is forced to do such heavy work is an elderly person or a person who is in a position to support the household budget, the burden on the caregiver becomes extremely unbearable and, for that reason, Has caused serious social problems.

Therefore, various proposals have been made to reduce the burden on caregivers to some extent, and some of these proposals have already been put to practical use. In the above proposal,
Various types of paper diapers and diaper covers have been put into practical use for a relatively long time. The above-described paper diapers include, for example, a bag formed by stacking and sewing a thin sheet having a waterproof function and a thin sheet having a water-permeable function, and a thick sheet having a water-absorbing power contained in this bag. It is equipped with it.

On the other hand, the diaper cover is also provided with a bag in which a thin sheet having a waterproof function and a thin sheet having a water-permeable function are laminated and stuck together, and a thick sheet having a water-absorbing capacity accommodated in the bag. There is. The waterproof thin sheet used for the paper diaper and diaper cover is made of a material made of a high molecular compound, and the thin sheet having a water permeable function is made of a nonwoven fabric. Further, the water-absorbing thick sheet is formed of various highly water-absorbent resins (which are already known) having a water-absorbing power of, for example, about 500 times its own weight. The paper diaper and the diaper cover having the above-mentioned configuration are used in a manner substantially similar to the case of applying to a baby.

Among the above proposals, a recently developed one is a urine collecting device for male and female urinary incontinence. 17 and 18 each show an example of the above-mentioned urine collecting device, in which the urinary device shown in FIG. 17 is a device for female urinary incontinence, and the urinary device shown in FIG. 18 is male urine. It is a device for incontinence. Each of the above urinary devices,
The structure is almost the same as a whole.

That is, the above-mentioned female urinary device includes a receiver 201 which is directed to the genital area of a female urinary incontinence person, a device body 203 which houses a urine tank (not shown) which stores excreted urine, and a receiver 201. Urine tank (not shown)
And a hose 205 for connecting urine flowing from the receiver 201 to a urine tank (not shown).
The urine collecting device having the above-mentioned configuration is used for urination of a female urinary incontinence person by the following procedure.

First, an empty urine tank (not shown) is housed in a urine tank housing chamber (not shown) in the apparatus body 203, and a lid (not shown) of the urine tank is set.
Next, a lid 207 hinged to the apparatus body frame
Is closed to close the urine tank accommodating chamber and communicates with the opening (not shown) of the lid.
The nozzle base 211 fixedly attached to one end of the hose 205 is attached to 09. When a power switch (not shown) of the apparatus main body 203 is turned on in this state, the apparatus main body 2
A power lamp provided on a display unit 03 (not shown) is turned on, and a urine suction mechanism (not shown) in the apparatus main body 203 is in a standby state. Here, the opening of the receiver body 201 is directed to the female vulva.

At this time, when the grip 213 is operated in the direction of the arrow in FIG. 12 and is held at the position after the operation, the opening is brought into close contact with the vulva of the female urinary incontinence person.
Since the opening is formed so as to conform to the shape of the vulva of the female urinary incontinence person, the degree of close contact between the opening and the vulva of the female urinary incontinence is increased by operating the grip 213. The pain caused by the part's vulva is alleviated. When a female urinary incontinence person urinates in this state,
A sensor 215 attached to the connection with the hose 205 detects the inflow of urine and outputs a predetermined urine detection signal.

When the urine detection signal is input, the urine suction mechanism starts the urine suction operation, and the excreted urine is discharged from the hose 20.
It is led to the urine tank through 5. When the urine tank is full, an alarm buzzer (not shown) informs that the urine tank is full, and an alarm lamp provided on the display section (not shown) blinks. When the sensor 215 becomes dirty, the alarm buzzer is driven and the sensor lamp provided on the display (not shown) blinks.

On the other hand, the male urinary device shown in FIG.
The receiver body 221 is different in structure from the female receiver 201 in that it has a substantially cylindrical shape for inserting a penis and the grip 223 has a handle shape. The parts are substantially similar to the women's device described above.

[0012]

By the way, the above-mentioned paper diapers are formed in a sheet shape, and moreover, this paper diaper has a waist including a crotch of a bedridden old man as well as being addressed to the crotch of an infant. It covers almost the entire area of the vulva and does not block the vulva or anus from other parts. Therefore, when the amount of excreted urine increases, the urine is transmitted from the crotch of the bedridden old man to the buttocks of the bedridden old man across one side of the disposable diaper.

In particular, when the above-mentioned paper diapers and diaper cover are continuously worn from bedtime until the next morning (about 6 to 8 hours), urine excreted by a bedridden old man during that period is entirely on one side of the paper diaper. There is a problem that it eventually overflows from the diaper cover and stains the bedding, or the bedridden old man turns from his buttocks to his back and stains the part of his clothes from his buttocks to his back. Also, the feces excreted from the bedridden old man had the same problem as in the urine due to the structure and the addressing of the paper diaper as described above.

Therefore, in order to prevent the occurrence of such a problem, the caregiver must replace the diaper several times during the night, which may make it difficult to sleep deeply. . And in the worst case, I couldn't sleep well and couldn't sleep all night.

Further, some bedridden old people cannot even hit the bed over, and when the above-mentioned urine reaches the tailbone of such bedridden old people, the tailbone, which is the most severe place such as bed sore and irritated skin, is caused. There may be a problem that the skin around the skin becomes inflamed and the skin is seriously damaged. Since the bedridden old man is generally thin, the meat around the buttocks is also dropped, and the coccyx part is projected, so that the above problem is serious. In particular, in the case of a bedridden old man, urination is more likely to reach the back from the vulva than in a man bedridden old man because of the anatomy (that is, the structure of the large and small labia surrounding the vulva where the urethral opening is open). As a result, the damage to the skin becomes even more severe.

Further, the above-mentioned paper diaper has a problem that the excreted feces are also circulated from the genital area or the buttocks to the back, as described above. It is a great burden on the caregiver. In female bedridden old people, when stool enters the vaginal opening through the perineum, it causes orimono, and in male bedridden old people, if stool adheres to the scrotum, it takes a lot of trouble to remove it. It was As described above, the conventional paper diaper and diaper cover have various problems.

On the other hand, although each of the above-mentioned urine collecting devices can be used in the supine position, the above-mentioned grip operation is involved and the receiver main body 201 (or 221) is suitable for men and women, respectively. The structure of the receiver 201 (or 221) is designed to receive bowel movements because it is made of a hard plastic material and does not feel good against the skin and cannot be worn for a long time. There are various problems, such as the absence of urine by the urine suction mechanism, because the surrounding air is sucked together with the urine when the urine is sucked, and the genital area of the bedridden elderly person is cooled by the surrounding cold air when the room temperature is low. Therefore, it is not suitable for bedridden elderly people whose motor function is significantly reduced.

Therefore, the present invention has been made in consideration of the above circumstances, and a first object of the present invention is to enable a bedridden elderly person to continue for a long time (at least the average sleep time of an adult) regardless of male or female. Even if it is worn, urine does not leak, the bedridden elderly person does not have bedsores and skin irritation, and even if there is defecation with urination, defecation does not enter the genital area or the back from the vicinity of the anus. The purpose of the present invention is to provide an excrement absorber that allows a caregiver to sleep well.

A second object of the present invention is to use the bedridden old man's hands without any trouble, and even if the person is directed to the pubic area for a long time, it does not cause any pain and can be turned over while wearing. An object of the present invention is to provide an excrement absorption device that does not allow defecation to enter the genital area or the back from the vicinity of the anus and does not cool the genital area and the vicinity thereof of a bedridden elderly person when sucking urine.

[0020]

In order to achieve the first object, the excrement absorber according to the first aspect of the present invention comprises:
At least the outer peripheral surface is covered with a soft flexible material having a waterproof function, the inner peripheral surface is covered with a water-permeable sheet, and a boat-shaped outer member having a built-in water-absorbing thick sheet, and an opening of the outer member. A partition member provided for partitioning the urine receiving part and the defecation receiving part, the surface of which is covered with a soft flexible material having a waterproof function, and the urine receiving part of the outer member, which is housed in the urine receiving part of the outer member. The excrement receiving member having a surface exposed over substantially the entire length of the opening on the part side, at least the surface portion of which is covered with a water-permeable sheet, and a water-absorbing thick sheet built-in, and defecation of the mantle member. The cushioning member is provided at the end portion on the receiving portion side, and has a through hole formed in a portion corresponding to the coccyx when worn on the crotch.

In order to achieve the above second object, a second aspect of the present invention is an excrement absorber which can be shared with the excrement absorber according to any one of claims 1 to 4. And a liquid receiving mechanism that is formed of a soft and flexible material so that it can be incorporated in the excrement absorber, and a liquid that detects that liquid has accumulated in the liquid receiving mechanism and outputs a predetermined electric signal. A detection means, a liquid storage mechanism communicating with the liquid receiving mechanism, a suction means for guiding the liquid stored in the liquid receiving mechanism to the liquid storage mechanism by a suction action, and a warm air,
When a predetermined electric signal is output from the warm air supply means and the liquid detection means, which are blown out to the outside through the liquid receiving mechanism in a state in which the temperature and the blown air amount are variable, the warm air supply means blows out The control unit controls the warm air supply unit and the suction unit so that the temperature and the amount of the warm air to be blown are values corresponding to the suction force of the suction unit.

[0022]

In the first aspect of the present invention, since the partition member is in close contact with the perineum of the bedridden old man when the excrement absorber is directed to the crotch, urine excreted from the bedridden old man is It flows into the urine receiving part side and is prevented from flowing from the urine receiving part side to the defecation receiving part side and the outside. Then, the urine that has flowed into the urine receiving part side is absorbed by the water absorbent thick sheet that constitutes the excrement receiving member on the urine receiving part side. On the other hand, the feces excreted from the bedridden elderly person are received by the defecation receiving portion side, and the invasion from the defecation receiving portion side to the urine receiving portion side and the outside is prevented.

Even if urine leaks from the excrement receiving member of the urine receiving part, it is absorbed by the water absorbent thick sheet through the water permeable sheet of the outer member facing the urine receiving part. Further, even if urine leaks from the water-absorbent thick sheet, it is possible to prevent urine from leaking to the outside because the outer peripheral surface of the mantle member is covered with a soft flexible material having a waterproof function.

Since the shape of the mantle member is set so as to fit snugly in the crotch of a human, unless the excrement absorber is separated from the crotch, urine in the urine receiving part leaks or stool on the side of the defecation receiving part. There are no problems such as turning around from the waist to the back or entering the genital area as described above. or,
Even if the bedridden old person remains supine for a long time, the area around the coccyx comes into contact with the bedding through the cushioning member,
It is possible to prevent skin roughness or the like from occurring on the skin covering the coccyx and its surroundings.

In the second aspect of the present invention, when urine is stored in the liquid receiving mechanism incorporated in the excrement absorber, the liquid detecting means outputs a predetermined electric signal to the control means. When this electric signal is input, the control unit controls the warm air supply unit and the suction unit so that the temperature and the amount of the warm air blown from the warm air supply unit have values corresponding to the suction force of the suction unit. Control.

As a result, the suction means starts the suction operation, and the warm air supply means starts the warm air supply operation. The urine stored in the liquid receiving mechanism is guided to the liquid storing mechanism communicating with the liquid receiving mechanism together with the surrounding air. The hot air blown out from the hot air supply means is controlled so that its temperature and the amount of air blown become a value commensurate with the amount of intake of ambient air due to the suction operation by the suction means, There is no risk of the crotch of the bedridden old man being cooled.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a perspective view showing an excrement absorber according to an embodiment of the present invention. The excrement absorber shown in FIG. 1 was created especially for women who are bedridden for the elderly, and is composed of a soft and flexible material as a whole, and the excrement absorber main body (hereinafter referred to as “main body”). 1)
And a cushion member 5. The main body 1 described above includes a housing portion 7, a partition wall 3 that partitions the housing portion 7,
One of the storage portions 7 of the storage portion 7 partitioned by the partition wall 3 (that is, a urine receiving portion for receiving urine from a female urethral opening) 7
The urine absorption part 9 accommodated in c.

The accommodating portion 7 is formed into a boat shape as a whole, that is, in a shape that fits the female vulva and the area from the perineum to the anus, which is the vicinity thereof, as shown in FIG. It has a flat and substantially elliptical opening and a bottom corresponding to the opening. The accommodating portion 7 is formed of a paper diaper 11 having a bag 13 including, for example, a waterproof thin sheet 17 and a water-permeable thin sheet 19, and a water absorbent thick sheet 15 housed in the bag 13. (See Figure 2). To further explain, the accommodating portion 7 has the paper diaper 11 shown in FIG. 2 in which the waterproof thin sheet 17 is positioned on the outer side of the side and the back of the bottom, and the water-permeable thin sheet 19 is positioned on the inner side of the side and the front side of the bottom. It is formed into a boat shape as described above.

Waterproof thin sheet 1 constituting the bag 13
7 is made of a known polymer material, and the water-permeable thin sheet 19 is made of a nonwoven fabric. Furthermore, the water-absorbent thick sheet 1
As described above, 5 is formed of various highly water-absorbent resins (which are already known) having a water absorption capacity of about 500 times its own weight, and urine that has penetrated through the water-permeable thin sheet 19 absorbs water. The thick sheet 15 is absorbed.

The partition wall 3 is provided for partitioning the accommodating portion 7 into the above-mentioned urine receiving portion 7c and the feces receiving portion 7d for receiving defecation from the anus, and is located at an intermediate position in the longitudinal direction of the accommodating portion 7. As shown in FIG. 1, the toilet seat 7 is attached and fixed so as to have a shape corresponding to the female perineum and its vicinity.
It is curved to the d side. The installation position of the partition wall 3 in the accommodating portion 7 is such that when the excrement absorber is placed in the crotch with the upper part of FIG. 1 being in contact with the vulva,
The position is set so as to cover the perineum located between the labia minora and anus. The partition wall 3 prevents the urine of the urine receiving portion 7c from leaking to the feces receiving portion 7d side or the feces of the feces receiving portion 7d entering the urine receiving portion 7c side when the excrement absorber is attached to the crotch. Function to block. This prevents stool from entering the ostium of the vagina that opens to the vulva and causing vaginitis and orimono.

The partition wall 3 is also formed of the paper diaper 11 having the structure shown in FIG. 2 similarly to the accommodating portion 7, and the paper diaper 11 is provided on the surface exposed to the opening side. It is formed by processing so that the waterproof thin sheet 17 is positioned.

In this embodiment, the paper diaper 11 is used as the material forming the partition wall 3, but the paper diaper 11 is used.
In addition, select a material that does not cause skin irritation or pain even if it is worn for a long time, such as a soft and flexible rubber material that can be freely deformed by human body temperature. May be.

The cushion member 5 is provided to prevent the tailbone from contacting clothes or bedding when the bedridden elderly woman wearing the above-mentioned excrement absorber is supine, and the feces receiving portion 7d is provided. Is fixedly attached to the longitudinal end of the. As shown in FIG. 1, the cushion member 5 is formed in a substantially disc shape, and an elliptical through hole 5a is provided in a substantially central portion thereof. This through hole 5a is for exposing the tail bones of a bedridden elderly woman when he or she is supine. The reason why the through hole 5a is formed into an elliptical shape is that the bedridden elderly woman of any physique can use this embodiment. This is because the excrement absorber can be applied.

The cushion member 5 need not be formed in a circular shape, as long as its size and shape are set so as to cover at least the region near the coccyx. Also, the shape of the through hole 5a may be set to a shape corresponding to the shape of the tailbone, that is, a substantially circular shape.

When the bedridden elderly woman is supine when the above-mentioned excrement absorber is attached, the tailbone thereof fits into the through hole 5a,
Therefore, the tailbone portion is restricted from coming into contact with clothes or bedding. Therefore, it is possible to prevent the skin covering the coccyx of the bedridden elderly woman from suffering from bedsores and rough skin. The cushion member 5 may be made of any material, such as sponge, as long as it can fulfill the above function. When the excrement absorber is shared with an excrement absorber described below, a hole (not shown) having an appropriate shape is formed at the bottom of the container 7.

FIG. 3 is a perspective view showing an excrement absorber according to another embodiment of the present invention. The excrement absorber shown in FIG. 3 is also designed especially for women who are bedridden for the elderly, and the accommodation section 7 and the urine absorption section 9 are formed by folding the paper diaper 11 shown in FIG. It is configured as a single unit. That is, the paper diaper 1
Reference numeral 1 denotes a cross-sectional shape viewed from the line BB ′ in FIG. 3, that is, a urine receiving portion 7c formed by the accommodating portion 7 and the urine absorbing portion 9.
5 is folded so that the cross-sectional shape thereof has a substantially W shape as shown in FIG. On the other hand, the disposable diaper 11 is A- of FIG.
The cross-sectional shape seen from the line A ′, that is, the cross-sectional shape of the feces receiving portion 7d is substantially W in the thin state where the urine absorbing portion 9 provided on the urine receiving portion 7c side is removed as shown in FIG. It is folded so as to have a letter shape.

The disposable diaper 11 is folded as described above with the waterproof thin sheet 17 positioned on the outer peripheral side and the water permeable thin sheet 19 positioned on the inner peripheral side, and required processing (for example, The removal of the urine absorbing portion 9 on the side of the feces receiving portion 7d) is performed. In the excrement absorber according to the present embodiment, the paper diaper 11 is folded such that the waterproof thin sheet 17 is positioned on the outside and the water permeable thin sheet 19 is positioned on the inside, whereby the container 7 and the urine absorbent body are absorbed. Since the part 9 and the part 9 are integrally formed with the above-described cross-sectional shape, one of the parts 7b of the accommodating part 7 that faces each other and defines the accommodating space is overlapped with the folded part. The wall thickness is thicker than the wall thickness of the other portion 7a.

The structures of the partition wall and the cushion member shown in FIG. 3 are the same as those shown in FIG. 1, so the same reference numerals as those in FIG. 1 are given and the description thereof is omitted.

FIG. 4 is a perspective view showing an excrement absorber according to still another embodiment of the present invention.

The excrement absorber shown in FIG. 4 is also designed especially for women who are bedridden and elderly, and the human waste absorbing / carrying part 10 having the same structure as the urine receiving part 9 from the urine receiving part 7c to the feces receiving part 7d. Is provided, which is different from the excrement absorber shown in FIG. Therefore, the paper diaper 11 shown in FIG.
The cross-sectional shape viewed from the line BB ′ and the cross-sectional shape viewed from the line AA ′ in FIG. 4 both have substantially the same wall thickness as shown in FIG. Is folded like.

Also in the case of this embodiment, the paper diaper 11 has the waterproof thin sheet 17 on the outer peripheral side and the water-permeable thin sheet 19.
Are positioned on the inner peripheral side and are folded as described above to form the excrement absorber. The cross-sectional shape of only the urine absorbing / supporting part 10 as viewed from the line AA ′ of FIG.
It is formed to have a letter shape.

FIG. 7 is a developed perspective view showing a diaper cover used when the above-mentioned excrement absorber is attached to the crotch. This diaper cover is composed of a thin mesh sheet 23 made of an elastic and flexible material, and is attached to both sides in the longitudinal direction of the diaper cover in order to prevent the diaper cover from being separated from the crotch when mounted, for example, a double-sided tape. Such an adhesive member 33 is attached. Unlike the conventional diaper cover, the diaper cover employs the thin mesh sheet 23, so that the diaper cover has good ventilation at the time of wearing and can prevent the crotch of a bedridden old man from getting damp. The size of the mesh of the mesh sheet 23 is not particularly limited, but is set to such a size that the receiver 35, the tubes 59, 61, etc. of the excrement absorber described later can partially pass therethrough. It is also possible to do so. The diaper cover used with the above-mentioned excrement absorber is not limited to the one shown in FIG. 7. Other than the above, for example, a so-called pants type diaper cover can also be used.

The above-mentioned excrement absorber is the paper diaper 11 shown in FIG. 2 or a so-called pants-type diaper,
It is used together with the diaper cover or the so-called pants type diaper cover. If the excrement absorber and the conventional paper diaper are put on the crotch, and the diaper cover is mounted on the crotch and fastened with the adhesive member 33, even if the temporary bedridden elderly person turns over, excretion is excreted. There is almost no risk of the object absorber coming off the crotch or the diaper cover coming off the crotch. This is because the excrement absorber has high adhesion to the crotch, and the diaper cover is restricted from being disengaged from the crotch by the lateral muscles in the thigh of a bedridden elderly woman. Here, how to address the excrement absorber, the disposable diapers, and the diaper cover will be described. First, place the excrement absorber on the crotch, and then place the diapers on it. The diapers may be the paper diapers 11 shown in FIG. 2 or so-called pants-type diapers. When the paper diaper 11 is used, the two paper diapers 11 are written in a cross shape on the crotch of the bedridden elderly woman. In this way, the excrement absorber and the diapers are addressed, and then the diaper cover or pants-type diaper cover shown in FIG. 7 is attached.

When the excrement absorber, the diaper and the diaper cover are attached in the above-mentioned manner, urine during normal bedtime is almost completely absorbed by the excrement absorber, and the excrement absorber absorbs the diaper cover. Of course, it does not leak to diapers. Therefore, the caregiver only needs to replace the excrement absorber that is wet with urine after getting up and does not need to perform a troublesome diaper change. Even when the bedridden elderly woman has a relatively hard defecation during bedtime, the stool remains in the stool receiving portion 7d, so that it is not necessary to change the diaper again. When a bedridden elderly person has diarrhea, the diarrhea stool will protrude from the stool receiving portion 7d into the diaper, so that it is necessary to replace the diaper. Invasion of the genital area is blocked. Further, the invasion of the diarrhea stool into the coccyx is blocked by the end of the stool receiving portion 7d on the side where the cushion member 5 is attached.

Here, the process of forming the excrement absorber shown in FIG. 4 from the above-mentioned paper diaper 11 will be described with reference to FIG.
Will be explained. First, the paper diaper 11 having the configuration shown in FIG. 2 is folded along its lengthwise direction at a distance of approximately 1/3 in the transverse direction (A) to (B).

Next, both longitudinal ends of the paper diaper 11 are bent in the direction of the arrow (B) in the figure to form the accommodating section 7 and the human waste absorbing / carrying section 10 (C in the figure). The above-mentioned portion 7b side of the housing portion 7 is attached and fixed with an adhesive tape or the like (FIG. 3D). As a result, the excrement absorber shown in FIG. 4 is formed.

According to the excrement absorber according to each of the above-described embodiments of the present invention, since the entire shape of the main body 1 is formed so as to fit the female crotch, it has a flat shape like a conventional paper diaper. Unlike other things, it fits closely to the female vulva and its vicinity, and is difficult to separate from the crotch. Therefore, if the excrement absorber is placed on the crotch, diapers are put on it, and the diaper cover (shown in FIG. 7) described above is further put on the diaper, the urine for clothes and bedding, etc. Not only leakage prevention, but also the problem of soiling diapers can be prevented. Therefore, it is possible to significantly reduce the work such as a diaper changing work that is a great burden on the caregiver.

As is clear from the contents described above, the body 1 of the excrement absorber shown in FIG. 4 is a paper diaper 11 having an extremely simple structure as shown in FIG. (Shown in FIG. 3), and the end of the paper diaper 11 that is overlapped with one of the opposing portions of the housing portion 7 formed thereby is locked to the above-mentioned portion with an adhesive tape or the like. It was done. Further, the body 1 of the excrement absorber shown in FIG. 3 can be formed by further removing the urine absorbing portion 9 on the side of the feces receiving portion 7d from the body 1. Therefore, the main body 1 can be produced by a simple process in a short time, and the excrement absorber can be supplied at a low price.

The partition wall 3 is formed in a shape suitable for the perineal part of the woman and the vicinity thereof, and is made of a material such as the paper diaper 11 and the soft and flexible rubber material described above. Therefore, when the upper part of the excrement absorber shown in FIGS. 1, 3 and 4 is placed in the crotch so as to contact the vulva, it is located between the labia minora and the anus. It will be in close contact with the perineum. Therefore, the partition wall 3 completely separates the space between the urine receiving part 7b and the feces receiving part 7c, and the urine of the urine receiving part 7b leaks to the feces receiving part 7c side when the excrement absorber is attached. The stool of the feces receiving portion 7c is prevented from entering the urine receiving portion 7b side. Therefore, it is possible to prevent the stool from entering the ostium of the vagina that is open to the vulva of a woman and causing vaginitis and orimono.

Further, as described above, since the partition wall 3 is made of a material such as the paper diaper 11 or a soft and flexible rubber material, it can be freely deformed according to the shape of the perineum, so that it is long. Even if it is worn for a long time, it is possible to avoid skin roughening and skin damage, and the user hardly feels pain.

Since the cushion member 5 is provided with the through hole 5a at a substantially central portion thereof, when the bedridden elderly woman wearing the excrement absorber is supine, the tailbone thereof is located within the through hole 5a. Since this prevents the coccyx part from coming into contact with clothing or bedding, the skin covering the coccyx can be prevented from causing bed sores and rough skin.

Further, unlike the conventional diaper cover, the diaper cover employs the mesh sheet 23, so that the diaper cover has good ventilation at the time of wearing and can prevent the crotch of a bedridden old man from getting damp.

It should be noted that the above description is only related to the content of each embodiment according to the present invention, and does not mean that the present invention is limited only to the above content. For example, the above-mentioned excrement absorber is designed especially to fit the crotch of a woman, but it can also be worn by a bedridden elderly man, and even when a bedridden elderly man wears it, it is roughly the same as when a bedridden elderly woman wears it. The same effect can be obtained.

That is, although the male vulva and the female vulva are completely different in structure, the distance between the vulva and the anus in men and women is approximately the same, and the excrement absorber is formed. Since each part is formed of a soft and flexible material, for example, not only the excrement absorber shown in FIGS. 3 and 4, but also the excrement absorber shown in FIG.
The urine absorption part 9 facing the opening of the storage part 7 and the human waste absorption /
It becomes possible to use the excrement absorbent body for men only by pushing the supporting portion 10 in the direction of the back surface of each figure. That is, since the penis and scrotum can be accommodated at least on the urine receiving portion 7c side by pushing the human waste absorbing / carrying portion 10 as described above, it is possible to attach the penis and the scrotum to a male crotch with high adhesion. Is.

FIG. 9 is a block diagram showing the overall structure of the excrement absorption device according to one embodiment of the present invention. The excrement absorption device shown in FIG. 9 is designed especially for a bedridden elderly woman, and is a receiver 35 (FIG. 10) formed so as to be attachable together with the excrement absorber and the diaper cover described above.
(See) is configured. The excrement absorption device starts with the above-described receiver 35 as shown in FIG.
