Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an excrement disposal member that can be disposed of in water in a flush toilet and treated.

[0002]

2. Description of the Related Art When a stoma is formed as an artificial anus or an artificial bladder due to intestinal or bladder disease, or when a fistula is formed due to various organ diseases, feces and urine which cannot be controlled by these stomas or fistulas themselves. And waste such as body fluids are discharged. For this reason, it is necessary to mount the excrement holding device on the stoma or fistula, and to receive the waste discharged at any time. In addition, excrement disposal members are used in various fields such as incontinence products, urine collection bags, excrement disposal devices at medical sites, pus trays, sanitary products, wound products, vomiting treatment products, animal feces treatment products, and the like. I have. In recent years, various regulations have been imposed on the treatment of substances that pollute the environment, and restrictions have been imposed on disposal sites. In particular, when discarding the stool, urine, blood, and vomit of humans and animals, separate the excrement disposal member such as a bag that contains these dirt from the waste, and wash the excrement disposal member to make it nonflammable. Must be disposed of. This washing and sorting is a very cumbersome task, especially painful for patients with physical disabilities, and sometimes impossible.

[0003] In order to solve this problem, there has been developed a member capable of directly discarding excrement disposal members containing wastes, for example, in a flush toilet, and various configurations have been proposed. As one of them, a bag is formed from a material in which a swellable, water-insoluble film is placed on the inside and a water-repellent, water-soluble film is placed on the outside, and during use, the dirt is held by the water-insoluble film, A colostomy pouch utilizing the property of dissolving a water-soluble film upon contact with water when discarded in water has been proposed (Japanese Patent Laid-Open No. 63-181758), and a basic substance is contained in a bag for excrement. A package for human excrement has been proposed in which the excrement is inserted into the excrement and the pH of the excrement is increased to 12 or more, thereby increasing the decomposition rate of the bag when the bag is dumped in water. JP
No. 60-122527). The former is a combination of a water-insoluble film and a water-soluble film, giving durability to excrement containing water during use and solubility when dumped in water. However, when it is dumped in water, it takes a certain time for the film to dissolve, and when it is dumped in a flush toilet, it does not flow out in a short time, and there is a high possibility of overflowing the flush toilet sometimes, and it also leaked Even if the form remains as it is and there is a high possibility that it will block the septic tanks and sewage facilities, and the method of increasing the decomposition rate of the film by adding the agent represented by the latter is complicated, and the handling of the agent is complicated, and the disease is weak. There is a problem that the operation is difficult for a person and there is a possibility that the toilet is damaged.

[0004] In order to enable the excrement disposal member to be discarded into a flush toilet, it must be durable against water-containing excrement and the like during use. Loses its form due to dispersion, dissolution, swelling, etc. in a short time,
Contradictory requirements must be met not to hinder the drains, septic tanks and associated equipment of flush toilets, but the prior art has not been able to satisfy both.

[0005]

SUMMARY OF THE INVENTION An object of the present invention is to provide a flush toilet which, when discarded in water, rapidly breaks the bag due to the flow of water and does not hinder the drain pipe, septic tank and other related facilities of the flush toilet. An object of the present invention is to provide an excrement disposal member that can be treated.

[0006]

In order to solve the above-mentioned problems, the present invention comprises a bag-shaped main body capable of storing excrement, and an inner surface of the main body which comes into contact with the excrement is made of a water-resistant material. The inner surface is provided with a portion where the mechanical strength of the inner surface is locally reduced. The portion where the mechanical strength is locally reduced can be obtained by forming one or more stripe-shaped grooves on the inner surface of the main body. In the present invention, the mechanical strength refers to a deformation resistance until the main body is broken when a load is applied to the main body.

When the present invention is applied to an excrement holding device to be mounted in an opening formed in a human body, the main body is formed in a bag and attached to the opening formed in the human body in the bag. And the inner surface of the bag body is formed of a water-resistant material, and the inner surface is provided with a portion where the mechanical strength of the inner surface is locally reduced. One or more stripe-shaped grooves running in the lateral, vertical, or diagonal direction of the bag can be provided on the inner surface of the bag as a portion of the inner surface having reduced mechanical strength.

[0008] The main body may be formed of a single film or a plurality of laminated films. In the case of forming with a plurality of films, it is advantageous for the bag breakability if the inner film which is in contact with the excrement is formed of a water-resistant material and the outer film is formed of a water-soluble material. When the main body is formed of a plurality of films, the stripe-shaped grooves are formed so as not to penetrate the innermost layer in the innermost layer film, or to expose the outer film which penetrates the innermost layer and is adjacent to the innermost layer. May be formed.

The stripe-shaped grooves can be run in parallel at uniform intervals or in parallel at uneven intervals.

When the material forming the main body is deodorant and the outermost part has water resistance, the main body can be used alone. If the material forming the main body does not have deodorant properties, if the main body is used alone, the odor from the excrement and the like stored in the main body may leak to the outside. It is preferred to use The treatment can be performed in a short time after excretion, and it is not always necessary to attach an outer bag when odor is not a problem. In addition, when the outermost part of the main body has a water-soluble property, there is a concern that the main body may be dissolved from the outermost part when sweating or bathing and getting wet while wearing on the human body. Therefore, it is preferable to use a water-resistant outer bag if necessary. That is, the attachment of the outer bag can be considered depending on the presence / absence of the deodorant property of the main body, the presence / absence of the outermost water resistance of the main body, and the use conditions. Since the outer bag is not contaminated with excrement or the like, it goes without saying that only the main body is processed and the outer bag can be reused.

The main body is formed not in a bag shape but in a sheet shape,
The inner surface of the sheet-shaped body that comes into contact with excrement may be formed of a water-resistant material, and the inner surface may be provided with a portion having a reduced mechanical strength of the inner surface. By wrapping excrement and the like inside the sheet-shaped body and discarding it in a flush toilet as it is, the sheet-shaped body is broken and decomposed and flows out.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a block diagram showing an embodiment of the present invention;

FIG. 1 shows an embodiment in which the present invention is applied to an excrement holding device to be mounted on an opening formed in a human body.
Is a front view, b is a rear view, c is a longitudinal side view taken along the line CC of d, d is an inside view of a film on the non-skin side constituting the main body, and e is an enlarged view taken along the line EE of d. It is sectional drawing. Reference numeral 1 denotes a main body formed as a vertically long bag body, which is formed by bonding a skin-side film 2 and a non-skin-side film 3 of the same shape at the peripheral portion. The skin-side film 2 has an opening 4 in the vicinity of the upper part, which is opposed to an opening formed in the human body. The opening 4 is provided with a face plate 5 and can be fixed around the opening of the human body by the adhesive layer 6. it can. The skin-side film 2 and the non-skin-side film 3 are formed of a water-resistant film, and a plurality of stripe-shaped grooves 7 extending in the horizontal direction as shown in FIG. (Four in the example shown). The stripe-shaped groove 7 is formed on the inner surface of the non-skin side film 3 so as not to penetrate the non-skin side film 3, as shown in FIG. The mechanical strength at that location is weaker than that at other locations.

Although the stripe-shaped grooves shown in FIG. 1 are formed so as to be arranged in parallel in the lateral direction of the bag body, the grooves are not limited to such a shape. FIG. 2 shows various other forms of the striped groove in the form of an inner view. In FIG. 2A, one groove 22 provided in the lateral direction at a position slightly below the inner surface of the bag 21, b is a groove 23 arranged in the longitudinal direction parallel to the inner surface of the elongated bag 21, and c is The recesses 24 and d, which are formed a little larger at a position slightly below the inner surface of the bag 21, are arranged in parallel in the horizontal direction as in the embodiment of FIG. 1, but the ends reach the periphery of the bag 21. This is an example of a groove 25 that is not provided. For example, a form in which one groove is provided in the center in FIG. 2B, and a form in which a plurality of such recesses are provided in FIG. 2C are also possible. When a plurality of grooves are arranged in parallel, the intervals between the grooves may be uniform or non-uniform, and the grooves may be arranged randomly without being parallel.

It is desirable that the body be made of a material whose inner surface in contact with the excrement is at least water-resistant, has durability enough to hold the excrement discharged during use, and easily breaks into a bag when discarded in a flush toilet. . The film constituting the main body can be formed in a single layer or a plurality of layers. In the case of a single layer, a biodegradable plastic such as an aliphatic polyester can be used. As the plurality of layers, for example, in the case of three layers, it is advantageous to form the inner layer with a water-resistant plastic film, the intermediate layer with a deodorant film, and the outer layer with a water-soluble film. In this case, a biodegradable plastic used in the case of a single layer can be used as the water-resistant plastic film, a polyvinylidene chloride film can be used as the deodorant film, and a polyvinyl alcohol film can be used as the water-soluble film of the outer layer. In the case of two layers, the inner layer can be formed with a water-resistant plastic film, and the outer layer can be formed with a deodorant film. Each film can use the same material as in the case of three layers. In the case of a plurality of layers, a stripe-shaped groove is provided in the inner layer, and the groove can be formed so as not to penetrate the inner layer or to penetrate the inner layer to reach an adjacent layer.

When the main body is formed in a bag body and an opening is provided in the bag body so as to face the opening formed in the human body, the portion for weakening the mechanical strength is provided on the side having the opening and the side having no opening. It can be provided on either side of the surface.

Next, an embodiment of the present invention will be described with reference to an endurance test as to whether or not there is enough strength to hold excrement during use, and a dumping test as to whether or not the main body is easily broken when dumped into a flush toilet. Will be described.

First, the case where the main body is formed in a single layer will be described.

Sample used: biodegradable plastic (trade name "Bionole", manufactured by Showa Kogyo Co., Ltd., product number # 10)
03, a polybutylene succinate) having a thickness of 30 μm, a length of 170 mm and a width of 110 mm, two rectangular films are stacked and the peripheral portions are welded to form a bag as shown in the rear view of FIG. 3 a and the vertical side view of FIG. 31 and a fixing face plate 34 is attached to an opening 33 formed in one of the films 32. As shown in the inner view of FIG. 3C and the partially enlarged sectional view of FIG. , Thickness p1 is 30μ
A groove 36 having a width q of 2.5 mm is provided for the film m.
The number and direction of the grooves, the depth of the grooves, that is, the film thickness p2 of the portion where the grooves were provided were variously changed to prepare the film. That is, as shown in the test result table 1 shown later, the one provided with the grooves in the horizontal direction is 48 m from the lower side in the vertical direction of the bag body 31.
m, a single groove having the center of the groove at the position of m, and an interval between the centers of the grooves of 24 at equal intervals in the longitudinal direction of the bag body 31.
mm having six grooves, two types of which are provided in the vertical direction, those having one groove in the center of the bag body 31 in the horizontal direction, and those having one groove in the lateral direction of the bag body 31 Even though there are four grooves with a uniform spacing between the centers of the grooves of 22 mm,
The type was prepared, and the thickness p2 of the film provided with the groove was changed in the range of 7 to 25 μm. In each of these bags, 200 g of artificial stool formed by putting 8% by weight of potato starch into boiled tap water and forming a muddy state was prepared to prepare samples.

Endurance test: As shown in the sectional view of FIG. 3e, each of the above-mentioned samples 31 containing the artificial stool 37 is inserted into a polyethylene outer bag 38 which is a water-resistant material for safety during the test. Affixed to the abdomen 39 of the human body by the face plate 34, performed daily operation without particularly keeping quiet or intense exercise, and affixed for 8 hours to check for leaks and tears. Passed.

Drainage treatment test: Each of the above-mentioned samples (without outer bag) was discarded into a flush toilet 310 (C770 seated tank tightly closed type manufactured by TOTO Kiki Co., Ltd.) as shown in FIG. The sample discharged from the discharge pipe 311 was checked for the presence or absence of bag breakage.

Table 1 shows the results of performing the test on each sample four times each.

[0023]

As can be seen from the table, when the thickness p2 of the stripe-shaped groove portion is 12 μm or less, the durability did not reach the practical stage, and therefore, the disposal test was not performed. When the thickness of the groove was 18 μm or more, sufficient durability was obtained in the durability test. However, when the groove was too thick, the bag did not break when it was discarded. Therefore, when the above-mentioned film material is used, the range of the film thickness of the groove portion of 12 to 17 μm satisfies both the durability and the dumping test. From these results, no particular influence was observed on the direction and the number of the stripe-shaped grooves, and the same result was obtained regardless of the vertical direction, the horizontal direction, and the number of the grooves. The thickness of the film at the portion where the stripe-shaped grooves are provided slightly differs depending on the material used, and each has an optimum numerical range.

Next, a test was conducted to determine how the durability and the breakability at the time of discarding were changed depending on the position of the stripe-shaped groove in the case where the main body had a single layer. Using the test sample described above, as shown in FIG. 3g, the center is located at positions 1 to 6 which are sequentially shifted downward by 25 mm with respect to the position of the film 35 facing the uppermost position of the opening 33.
Only one 5 mm-wide groove is formed in the lateral direction, and six bag bodies having a film thickness (p2) of 15 μm in the portion where the groove is provided are prepared, and the same durability test and dumping treatment as described above are performed. The test was performed four times each. Table 2 shows the results.

[0026]

[Table 2] Groove position Endurance test Dump test -------------------------------------- ---------- 1 Pass Fail 2 Pass Fail 3 Pass Pass 4 Pass Pass 5 Pass Pass 6 Pass Pass

From these results, it is found that the positions 1 and 2 near the opening 33 are
In some cases, the opening provided in the opening 3
It can be seen that if a groove is formed at a position lower than 3, the bag will always break when discarded. This is considered to be due to the fact that excrement usually accumulates below, and when it is discarded in the flush toilet and entrained in the water flow, the excrement is prone to the force of the water flow because the excreted portion is raised. Providing a groove below is advantageous in terms of bag breakage when discarded.

Next, the results when the main body is formed in a plurality of layers, that is, two layers, will be described.

Samples used: As shown in FIG. 4, a biodegradable plastic (trade name "Bionore",
A film material 41 having a thickness p1 of 25 μm and a vinylidene chloride film (manufactured by Asahi Kasei Kogyo Co., Ltd., product number F216) having a thickness p2 of 10 μm. 3a, two rectangular films each having a length of 170 mm and a width of 110 mm are stacked and the periphery is welded to form a bag similar to that shown in FIG. 3A. 5m
m are provided in the form of stripes 43 at regular intervals in the longitudinal direction of the bag body, and six grooves each having a distance between the centers of the grooves of 24 mm are provided. The thickness p3 of the grooved portion is set to 19 to 26 μm.
Was created in the range of. In each of these bags, the same artificial stool 20 as used in the previous test was used.
A sample was made by inserting 0 g.

Table 3 shows the results of the same durability test and discarding test as described above, using the above-mentioned samples.

[0031]

[Table 3] Groove thickness p3 Endurance test Dumping test ----------------------------------- --------- 19μm Fail-19μm Pass Pass 19μm Pass Pass 19μm Fail-21μm Pass Pass 21μm Pass Pass 21μm Pass Pass 21μm Pass Pass 23μm Pass Pass 23μm Pass Pass 23μm Pass Pass 23μm Pass Pass 25μm Pass Pass 25μm Pass Pass 25μm Pass Pass 26μm Pass Fail 26μm Pass Pass 26μm Pass Fail 26μm Pass Fail

As can be seen from this table, when the film thickness of the stripe-shaped groove portion is 19 μm or less, the durability is unstable, and the reliability in practical use is lacking. On the other hand, the film thickness of the groove portion is 26 μm. As described above, although sufficient durability was obtained in the durability test, no bag breakage occurred when discarded. Therefore, when the above-mentioned film material is used, the range of the film thickness of the groove portion in the range of 21 to 25 μm satisfies both the durability and the disposal test.

Next, the results when the main body is formed in three layers will be described.

Samples used: As shown in FIG. 5, a biodegradable plastic (trade name "Bionore",
A film material 51 having a thickness p1 of 18 μm and a vinylidene chloride (manufactured by Asahi Kasei Kogyo Co., Ltd., product number F216) having a thickness p2 of 10 μm. 52, a laminate of film materials 53 of 25 μm in thickness p3 of polyvinyl alcohol (manufactured by Aicello Chemical Co., Ltd., product number KL-25) as an outer layer, and two square films each having a length of 170 mm and a width of 110 mm are stacked. 3a, a groove 44 having a width q of 2.5 mm is provided on the surface of the film material 51 of the inner layer in the same manner as in FIG. 3c, and the number, direction, A film was prepared in which the depth of the groove, that is, the thickness p4 of the film where the groove was provided, was changed in the range of 38 to 48 μm. The number and direction of the grooves were determined in the same manner as in the single-layer test sample described above, as shown in Table 4 of the test results shown below. Samples were prepared by inserting 200 g of artificial stool similar to that used in the previous test into each of these bags.

Table 4 shows the results of the same durability test and discarding test as those of the above-mentioned single-layer sample.

[0036]

[Table 4] Groove thickness p4 direction Number Endurance test Dump test --------------------------------- --------------------------- 38μm length 1 failure-38μm length 4 failure-38μm width 1 failure-38μm width 6 failure -39 μm length 1 pass pass 39 μm length 4 pass pass 39 μm width 1 reject-39 μm width 6 reject-41 μm length 1 pass pass 41 μm length 4 pass pass 41 μm width 1 pass pass 41 μm width pass pass 43 μm pass pass 43 μm 4 Passed Pass 43 μm Horizontal 1 Passed Passed 43 μm Horizontal 6 Passed Passed 45 μm Vertical 1 Passed Passed 45 μm Vertical 4 Passed Passed 45 μm Horizontal 1 Passed Passed 45 μm Horizontal 6 Passed Passed 46 μm Vertical 1 Passed Passed 46 μm Vertical Passed 6 Pass Pass 48μm Vertical 1 Pass Fail 48 μm Vertical 4 Pass Fail 48 μm Horizontal 1 Pass Pass 48 μm Horizontal 6 Pass Pass

As can be seen from the results, when the above-mentioned film material is used, when the thickness of the groove portion is 39 μm or less, that is, when the thickness of the inner layer is 4 μm or less, the durability is not reliable. When the thickness of the portion is 48 μm or more, that is, when the thickness of the inner layer is 13 μm or more, the bag may not break when discarded. In the case of this three-layer sample, since the outermost layer is water-soluble, the outermost layer is dissolved by being discarded in water, so the thickness of the groove portion that breaks the bag is thicker than in the case of the single layer or the two layers. The practical range of the thickness of the groove portion is 41 to 46 μm, and the range of the thickness is slightly wider than in the case of two layers. In the case of a three-layer structure also a single layer,
As in the case of the two layers, the thickness of the portion provided with the groove is selected to an appropriate value according to the material used.

The above-described embodiment is an example of the excrement holding device to be attached to the opening formed in the human body. Depending on the use conditions, the opening corresponding to the opening formed in the human body may be provided in the bag of the main body. No need to provide. FIG. 6 shows an example. The main body 61 is formed in a bag shape by laminating films, but does not have a side opening facing the opening formed in the human body, and has an opening 62 for introducing excrement and the like at an upper portion. And a stripe-shaped groove 63 is formed on the inner surface. After the excrement or the like is put into the main body through the opening 62, the main body can be tied and sealed with the opening 62 as shown in FIG. The opening 62 may be provided with a sealing fastener that can be opened and closed. This type of excrement disposal member can be used for etiquette bags for treating vomit, etc., for treating feces of pets, and the like.

In all of the above embodiments, the main body is formed in a bag, but it may be formed in a sheet. FIG. 7 shows an example. The main body 71 is formed of a single sheet having an appropriate size, and a stripe-shaped groove 72 is formed on almost the entire inner surface of the sheet. This body 71 is shown in FIG.
As shown in (2), excrement and the like can be wrapped in, for example, a wrapping paper style and discarded in a flush toilet. Since the position of the excrement or the like to be wrapped is not fixed as in the case of the bag, it is preferable to form the groove 72 on the whole.

In the above embodiment, the main body has been described. However, if the main body has no deodorizing property, the odor leaks to the outside when excretions are excreted. Is inappropriate. If the outermost part of the main body is made of a water-soluble material, it may be dissolved when worn on the body and sweating or taking a bath. Therefore, it is preferable to cover the main body with an outer bag having deodorant properties, water resistance, or both. 8A and 8B show an embodiment using an outer bag for wrapping the main body, wherein a is a front view, b is a longitudinal sectional view taken along the line BB of a, and the same reference numerals are given to the same parts as in FIG. 1c.

In this embodiment, on the surface of the face plate 5 on the non-skin side (the side having the main body 1), the main body 1
An outer bag 81 is fixed with its opening 82 by, for example, welding. In use, the face plate 5 is fixed around the opening of the human body with the adhesive layer 6 of the face plate 5, and when excrement accumulates in the main body 1 and the main body 1 is to be treated, the face plate 5 is removed from the opening of the human body and the outer bag is opened. If the body 81 is peeled off from the face plate 5 at the opening 82 and the main body 1 is discarded in the flush toilet, the main body is disassembled and discharged. Since the outer bag 81 is not contaminated with excrement or the like, it can be treated as ordinary waste as it is. The material of the outer bag is determined according to the required conditions. That is, when the main body has no deodorant function, a deodorant material is used. When the outermost part of the main body has a water-soluble property, a water-resistant material. In the case of properties, a deodorant and water-resistant material is used. Even if the outermost part of the main body is water-soluble, if there is no danger of getting wet on the outside due to sweating or bathing, or if it is possible to treat in a short time after excretion and it is not necessary to consider water resistance, put it on the outer bag. It is not necessary to have water resistance. In addition, even when the main body is deodorized and the outermost part is water-resistant, an outer bag may be further used to prepare for an accident.

Table 5 shows the possibility of various combinations of the properties of the innermost layer, the intermediate layer, and the outermost layer of the main body when the main body is composed of a single layer, two layers, and three layers. It shows the necessity of the bag and the minimum necessary properties of the outer bag.

[0043]

[Table 5]

In this table, "water-soluble" means soluble in cold water and instantaneous solubility. If any part of the main body has a deodorizing function and the outermost layer is water-resistant, basically the main body can be used alone and there is no need to use an outer bag. If any part of the main body has no deodorant function and the outermost layer is water-soluble, use an outer bag that wraps the main body when deodorization and water resistance are required depending on use conditions. In this case, the outer bag needs to be waterproof or deodorant or both depending on the use conditions. Even if the main body has a deodorizing function, a water-resistant outer bag may have to be used if the outermost layer is water-soluble. The above examples do not necessarily require the material required for the outer bag, but include examples added to further assure water resistance or deodorization. In addition, even when the outer bag is unnecessary, the outer bag can be provided to further enhance the reliability in use. The above table is only a part of combinations of materials that can be used for each layer, and various combinations other than this combination are possible.

The following materials can be used for the layers constituting the single layer, the second layer and the three layers shown in Table 5, for example.
Waterproof and deodorant materials include polyvinylidene chloride,
Ethylene-vinyl alcohol copolymer, nylon, acrylonitrile and the like. Water-resistant and non-odor-proof materials include polyethylene, polypropylene, polystyrene, polybutadiene, ethylene-vinyl acetate copolymer, polyvinyl chloride, polyethylene terephthalate, polyamide, cellulose acetate, cellulose acetate butyrate, phenolic resin, melamine resin, polyurethane, There are plastics such as silicone and all biodegradable resins. As the water-soluble material, synthetic polymers such as polyvinyl alcohol, polyvinylpyrrolidone, and polyethylene oxide, and various natural polymers such as carboxymethylcellulose can be used.

[0046]

According to the excrement disposal member of the present invention, when the excrement is dumped in a flush toilet with the excrement stored therein, when the excrement is discharged together with the water, the bag is immediately broken by the running water, and the septic tank and the sewage equipment are discharged. Can be disassembled so as not to cause trouble, and there is no fear that overflow occurs in the flush toilet.
