TECHNICAL FIELD OF THE INVENTION
The present invention is mounted on an opening formed in a human body, temporarily stores excrement, excreted liquid, and the like (hereinafter collectively referred to as excrement) discharged from the opening, and removes odor of excrement. The present invention relates to an excrement storage device provided with a deodorizing filter for use.
[0002]
[Prior art]
Incontinence of stool, urine, people who have undergone surgery for intestinal and urinary organ disorders and led the intestinal tract or ureter to the surface of the body and built a stoma on the body surface, or other diseases on the body surface Persons who have built the stoma or fistula have built a waste storage device that can temporarily store the waste, in order to process the waste such as stool, urine, and body fluid discharged from the openings where the stoma and fistula have been built. Attach it to the opening. This excrement storage device generally comprises a face plate and a bag, and the face plate is adhesively fixed around the opening on the body surface, and has a function of guiding the excrement to the bag so as not to leak and holding the bag. I have. The excrement may contain odorous gas, and the gas accumulates in the bag as the excrement is discharged.Therefore, if the gas is not removed properly, the bag may eventually burst or the face plate may come off. If the bag ruptures, a large amount of excrement will leak out. In order to avoid such a situation, a deodorizing filter is provided in a part of the bag body, and gas discharged into the bag body is radiated outside the bag body through the deodorizing filter. At this time, if the deodorizing filter is directly exposed to the excrement, the excrement adheres to the surface of the filter, causing the filter to be clogged and the air permeability to drop. May leak out. In order to solve this problem, a filter material having air permeability and waterproofness is provided as an intermediate wall in order to isolate the deodorizing filter from the inside of the bag, so that gas can be satisfactorily permeated and contact between the filter and excrement is cut off. (Japanese Patent No. 2765586).
[0003]
However, the filter material used for the intermediate wall is generally hydrophobic and does not cause water to permeate or adhere thereto.However, since it is lipophilic, oil components in stool penetrate into the filter material and become clogged. As a result, the air permeability is remarkably reduced, gas cannot escape, and the contents of the bag leak out of the bag. This phenomenon is particularly evident in water-like and muddy stools with ileostomy and soft stool properties. Because ileostomy is constructed by extending the ileum to the surface of the body, the absorption of bile acids normally performed at the terminal part of the ileum is insufficient, and the excretion contains a large amount of fat-soluble bile acids Will be. In addition, ileostomy easily causes lipid absorption failure in the ileum, and stool often contains a large amount of lipids. From this, the oil component in the stool permeates and passes through the lipophilic material of the intermediate wall, causing the bag contents to leak. In addition, even in the case of colostomy, diarrhea occurs depending on the diet and physical condition ingested, and the condition becomes similar to that of ileostomy.
[0004]
As described above, according to the conventional technology, it is impossible to completely prevent the oily component contained in the stool from penetrating or adhering to the intermediate wall, prevent the contents of the bag from leaking, and achieve good air permeability. There is no excrement holding device capable of maintaining the above.
[0005]
[Problems to be solved by the invention]
An object of the present invention is to provide an excrement holding device with a deodorizing filter that maintains air permeability, easily releases gas in the bag, and does not leak excrement in the bag.
[0006]
[Means for Solving the Problems]
In order to solve the above-described problems, according to the present invention, a bag that is attached to an opening formed in a human body and receives excrement discharged from the opening, a gas discharge through hole provided in the bag, A deodorizing filter arranged to communicate with the gas discharge through hole to deodorize odors from the excrement, and a gas-permeable and hydrophobic intermediate wall arranged to isolate the deodorizing filter from the inner space of the bag body, Made of lipophilic material placed on the opposite side of the deodorizing filter near the intermediate wall Including fiber material And a shield having a gas passage from the interior space of the bag to the intermediate wall.

[0007]
In the present invention, the deodorizing filter is attached to the inside surface of the bag so as to face the gas discharge through-hole, and the intermediate wall and the shield can be sequentially arranged on the side opposite to the gas discharge through-hole of the deodorization filter. .
[0008]
Further, in the present invention, a deodorizing filter is attached so as to face the gas discharge through-hole on the outer surface of the bag, and the intermediate wall and the shield are sequentially arranged so as to face the gas discharge through-hole on the inner surface of the bag.

[0009]
Further, in the present invention, a shield may be attached to the outer surface of the bag so as to face the gas discharge through-hole, and an intermediate wall and a deodorizing filter may be sequentially arranged on the side of the shield opposite to the gas discharge through-hole. it can.
[0010]
Advantageously, a gap is provided between the opposing surfaces of the intermediate wall and the shield so that moisture generated between the two can be discharged downward from the gap. As means for providing this gap, heat treatment is performed on the shield to bend it in a convex shape, or the shield is fixed on a support that is made of synthetic resin and is partially bent in a convex shape. There is a method in which the projection is formed so as to be curved at least partially in a convex shape, and the convex side is opposed to the intermediate wall.
[0011]
The shield may partially cover the opposing surface of the intermediate wall, and a portion of the intermediate wall exposed from the shield may serve as a gas passage from the internal space of the bag body to the intermediate wall. Further, by providing the shield with air permeability, the shield itself may be used as a gas passage from the internal space of the bag body to the intermediate wall. In this case, the shield covers the entire opposite side of the intermediate wall. You can also. As a method for imparting air permeability to the shield, there is a method in which the shield is formed of a material having air permeability, or a method in which a slit or a hole-shaped air passage is formed.
[0012]
A deodorizing filter is attached to the inside surface of the bag so as to face the gas discharge through-hole, and covers the entire surface of the deodorization filter opposite to the gas discharge through-hole and removes excrement so as to be separated from the surface of the deodorization filter. It is also possible to arrange a non-permeable film and fix the intermediate wall and the gas-permeable shield to the film so as to face the air holes provided in the film. In addition, a deodorizing filter is installed on the outer surface of the bag, not on the inner surface of the bag, so as to face the gas discharge through-hole, and a film that is impermeable to excrement is placed so as to cover the gas discharge through-hole. The intermediate wall and the air-permeable shield may be fixed to the film so as to face the air holes provided in the film. In these cases, the intermediate wall and the shield are fixed to the deodorizing filter side of the film, or the intermediate wall and the shield are fixed sequentially to the opposite side of the film deodorizing filter, or sequentially to the deodorizing filter side of the film. There is a method of fixing the shield and the intermediate wall.
[0013]

The shield can be made a part of the gas passage by providing the shield with air permeability by adjusting the manner of construction, that is, for example, adjusting the air permeability and the fiber aperture ratio when forming a nonwoven fabric.
[0019]
Next, a method of using the brace shown in FIG. 1 will be described. The release paper 5 of the face plate 1 is removed, and the opening formed in the human body and the opening 6 of the face plate 1 are aligned with each other to be adhesively fixed to the surface of the human body with the adhesive layer 4. The opening 16 at the lower end of the bag 2 is closed by an appropriate means. The excrement is discharged from the opening of the human body into the bag 2 through the opening 6 of the face plate 1. The gas and odor generated from the excrement pass through the intermediate wall 13 exposed below the shield 14 and reach the deodorizing filter 12 as shown by the solid line arrow, where the odor is absorbed, and the gas passes through the through-hole of the outer film 8. It is released to the outside world through 10. When the gas is filled in the bag 2, the bag 2 can be forcibly discharged by pressing the bag 2 by hand or the like. The excrement is blocked by the shield 14 and the intermediate wall 13 and does not enter the area where the deodorizing filter 12 is present. In particular, the oily components contained in the excrement are absorbed or adsorbed by the shield 14 and the intermediate wall 13 Only a small amount of the oily component adheres to the surface of the intermediate wall 13, the period until the intermediate wall 13 is clogged is extended, and the air permeability of the intermediate wall 13 is more effective for a longer time than in the past. Will be retained. When the shield 14 has air permeability in addition to the lipophilicity, the gas passes not only through the intermediate wall 13 but also through the shield 14 as shown by a broken arrow and reaches the deodorizing filter 12. The moisture generated between the shield 14 and the intermediate wall 13 or the moisture that has entered between them is discharged downward through the gap 15 existing between them, and acts so as to further maintain the air permeability of both.
[0020]
FIG. 2 is an enlarged sectional view of a main part of another embodiment of the present invention, in which a deodorizing filter is attached to an outer surface of a bag. The same parts as those in the embodiment of FIG. 1 are denoted by the same reference numerals. The deodorizing filter 12 is mounted on the outer surface of the outer film 8 and communicates with the internal space 11 of the bag body through the gas discharge through-holes 10. The filter 8 is mounted on the inner surface of the film 8 by means of heat welding or the like. As a result, the deodorizing filter 12 is isolated from the inner space 11 of the bag 2 by an intermediate wall 13. Further, a shield 14 made of a lipophilic material is disposed in the vicinity of the intermediate wall 13 on the side opposite to the gas discharge through-hole 10, and the shield 14 covers the upper portion of the intermediate wall 13 but is a small portion of the lower portion of the intermediate wall 13. Is mounted so as not to be covered, and a gap 15 exists between the opposing surfaces of the intermediate wall 13 and the shield 14. According to this orthosis, gas and odor generated from excrement pass through the gas discharge through hole 10 of the outer film 8 of the bag 2 from the region of the intermediate wall 13 exposed in the internal space 11 of the bag 2. Then, it reaches the deodorizing filter 12, where the odor is absorbed and the gas is released to the outside. The excrement is blocked by the shield 14 and the intermediate wall 13 and does not reach the deodorizing filter 12. In particular, the oily component in the excrement is absorbed or adsorbed by the shield 14, and only a small amount of the oily component adheres to the surface of the intermediate wall 13, and the period until the intermediate wall 13 is clogged is reduced. It extends, and the air permeability of the intermediate wall 13 is kept good for a long time. In this type of brace, the deodorizing filter 12 can be easily replaced from the outside.
[0021]
In the embodiment of FIGS. 1 and 2, the shield 14 covers the upper part of the intermediate wall 13 and the lower part of the intermediate wall 13 is exposed from the shield 14, but the shield is not necessarily the upper part of the intermediate wall. It is not necessary to cover the side wall or the lower part of the intermediate wall.
[0022]
FIG. 3 is an enlarged sectional view of a main part of still another embodiment of the present invention, in which a deodorizing filter, an intermediate wall, and a shield are all mounted on the outer surface of a bag. The same parts as those in the embodiment of FIG. 1 are denoted by the same reference numerals. The shielding body 14 made of a lipophilic material is attached to the outer surface of the outer film 8 of the bag body 2 by heat welding or the like so as to face the gas discharging through hole 10. It communicates with the space 11. The intermediate wall 13 is disposed outside the shield 14, and a part of the intermediate wall 13 is exposed to the gas discharge through hole 10 without being covered by the shield 14, thereby forming a gas passage. A deodorizing filter 12 is disposed further outside the intermediate wall 13 so as to cover the entire outer surface of the intermediate wall. The deodorizing filter 12 is isolated from the internal space 11 of the bag body by a shield 14 and the intermediate wall 13. According to this orthosis, gas and odor generated from the excrement pass through the gas discharge through hole 10 of the bag body 2 and reach the deodorizing filter 12 from the region of the intermediate wall 13 exposed to the gas discharge through hole 10. There, the odor is absorbed and the gas is released to the outside world. The excrement is blocked by the shield 14 and the intermediate wall 13 and does not reach the deodorizing filter 12. In particular, the oily component in the excrement is absorbed or adsorbed by the shield 14, and only a small amount of the oily component adheres to the surface of the intermediate wall 13, and the period until the intermediate wall 13 is clogged is reduced. It extends, and the air permeability of the intermediate wall 13 is kept good for a long time. This type of equipment also allows the deodorizing filter to be easily replaced from outside.
[0023]
In the above embodiment, the shield does not entirely cover the opposite side of the intermediate wall. However, the shield may cover the entire opposite side of the intermediate wall. FIG. 4A is an enlarged sectional view of a main part of such an embodiment, and FIG. 4B is an exploded perspective view thereof. 1 are given the same reference numerals. The shield 14 is formed slightly larger than the intermediate wall 13, and is mounted on the inner surface of the outer film 8 so as to cover the entire intermediate wall 13. In this case, since the shield 14 does not have the exposed portion of the intermediate wall 13 below it as in the above-described embodiments, it is necessary to configure the shield 14 to have air permeability in addition to lipophilicity. The gas passage is formed through the shield 14, the intermediate wall 13, and the deodorizing filter 12, as indicated by the solid arrow. Although FIG. 4 shows an example in which the deodorizing filter, the intermediate wall, and the shield are all inside the bag, it is needless to say that the same can be applied to the arrangement of three members as shown in FIGS.
[0024]
FIG. 5 is an enlarged sectional view of a main part of a further different embodiment of the present invention, and b is an exploded perspective view thereof. 1 are given the same reference numerals. The deodorizing filter 12 is attached to the inner surface of the bag body 2 so as to face the gas discharging through hole 10, covers the entire surface of the deodorizing filter 12 on the side opposite to the gas discharging through hole 10, and The film 17 is welded and fixed inside the bag body 2 so as to be separated therefrom. That is, the deodorizing filter 12 is configured to be separated from the internal space of the bag body 2 by the film 17. The film 17 has a ventilation hole 18 formed by a through hole. An intermediate wall 13 is fixed to the deodorizing filter 12 side so as to face the ventilation hole 18, and a shield 14 is provided on the opposite side to the deodorizing filter 12. Similarly, it is fixed so as to face the ventilation hole 18. According to this configuration, the intermediate wall 13 and the shield 14 are integrally fixed to the film 17 and are independent of the deodorizing filter 12, so that a gas discharge channel indicated by an arrow for the deodorizing filter 12 is secured, Gas can be satisfactorily discharged, and an intermediate wall and a shield can be provided at any position regardless of the position of the deodorizing filter. The ventilation holes 18 formed in the film 17 need to be smaller than the sizes of the intermediate wall 13 and the shield 14. The shield needs to be breathable in this case. The material of the film is not particularly limited, but it is necessary that the film is impermeable to excrement. Using the same material as the material of the bag is advantageous when the film is attached to the bag by welding or the like.
[0025]
FIG. 5C shows an example in which a part of a is deformed, and an intermediate wall 13 and a shield 14 are sequentially attached to the opposite side of the film 17 from the deodorizing filter 12, and FIG. However, in the example in which the shield 14 and the intermediate wall 13 are sequentially attached to the film 17 on the side of the deodorizing filter 12, the same effect can be obtained.
[0026]
Further, in each embodiment shown in FIG. 5, a plurality of intermediate walls and shields may be dispersedly arranged on the film 17 so as to further enhance the gas discharge.
[0027]
In the embodiment shown in FIG. 5, the deodorizing filter 12 is arranged on the inner surface of the bag, but the deodorizing filter 12 is arranged on the outer surface of the bag 2 so as to face the gas discharge through-hole 10. Attachment, a film 17 impermeable to excrement is disposed inside the bag 2 so as to cover the gas discharge through hole 10, and the intermediate wall 13 and the intermediate wall 13 are opposed to the air holes 18 provided in the film 17. The air-permeable shield 14 may be fixed to the film 17.
[0028]
Although the present invention has been described with reference to the so-called one-piece type embodiment in which the face plate and the bag are directly connected, the present invention can be similarly applied to a so-called two-piece type in which the face plate and the bag can be separated. .
[0029]
Next, the results of a comparison test of the excrement holding device with a deodorizing filter according to the present invention and the conventional excrement holding device with a deodorizing filter are shown for the gas leakage and the presence or absence of leakage of the bag contents. The excrement holding device with a deodorizing filter of the present invention was prepared according to the embodiment shown in FIG. 1, and a polyethylene film was laminated on both sides of a disc-shaped activated carbon sheet having a diameter of 25 mm and a thickness of 3 mm as a deodorizing filter. Using the same hole as the gas exhaust through-hole provided at the deodorizing filter mounting point of the bag body, molding an acrylic copolymer on a polyamide resin film in a circular shape with a diameter of 40 mm and a thickness of 200 μm as an intermediate wall A filter having an air permeability of 0.07 sec / 100 ml and a circular shape having a diameter of 40 mm and a thickness of 4 mm and made of porous polypropylene fibers of 0.07 sec / 100 ml was used as a shielding member. , An intermediate wall, and a shield on the inner surface of a bag made of a three-layer laminate of polyethylene / polyvinylidene chloride / polyethylene. The gas discharge through-hole was fitted so that the through-hole provided in one of the polyethylene films of the deodorizing filter coincided with the through-hole. The shield covered 2/3 of the intermediate wall. Further, as Comparative Example 1, a device excluding the shield from the above-described excrement holding device of the present invention was produced, and as Comparative Example 2, a device obtained by further removing the intermediate wall from Comparative Example 1 was produced.
[0030]
Each of the test pieces described above was filled with air to form a sealed state, and a gas release test was performed by manually applying pressure to the bag body. In addition, the intermediate wall of each of the above-mentioned test specimens, and the excrement contact side exposed surface of the shield face upward, and 5 ml of oleic acid (manufactured by Junsei Chemical Co., Ltd.) is dropped on the upper surface thereof as an oil component so as to spread evenly. Put 10 x 10 cm absorbent cotton on the surface, absorb oleic acid to the extent that it can be naturally absorbed by the weight of the absorbent cotton, remove excess oleic acid, and in this state, fill each specimen with air and seal in the same manner as described above. A gas leak test was performed on a simulated state in which an oily component was attached to the shield and the intermediate wall by applying pressure to the bag body by hand.
[0031]
In addition, each of the test pieces described above was filled with water in a sealed state by filling the bag with the water, and pressure was manually applied to the bag to confirm whether or not water leaked from the filter portion.
[0032]
Table 1 shows the results of the gas release test and the water leak test described above. The outgassing test was evaluated according to the following steps. A means that gas is released only by pressing lightly, B means that gas is released if a slight force is applied, C means that gas will not be released without applying a considerable force, and D means that gas is almost released even when a force is applied. Absent.
[0033]
[Table 1]

[0034]
As can be seen from this table, the excrement holding device with a deodorizing filter of the present invention obtained a result that even after applying the oily component, the gas could be satisfactorily removed by applying only a little force, and there was no leakage of the contents. On the other hand, those with an intermediate wall do not leak the contents, but the oil component adheres, but the gas release is remarkably reduced, and those with only the deodorizing filter have good gas release even after the oil component adheres, but the contents are good. Leakage occurred, and all of them had serious problems in use.
[0035]
【The invention's effect】
(1) According to the present invention, even if the excrement contains an oily component, it is effectively absorbed or adsorbed by the shield, and the oily component adheres to the intermediate wall placed in front of the deodorizing filter to reduce the air permeability. The gas present in the bag can be easily discharged to the outside without damaging or excrement leaking through the intermediate wall. You can live your daily life without feeling uncomfortable or uncomfortable due to storage.
(2) By adding a film that entirely covers the deodorizing filter and separates it from the deodorizing filter, and using an intermediate wall and a shield on this film, gas is discharged from the internal space of the bag to the deodorizing filter. The flow path is securely held, and the gas generated in the bag body can be satisfactorily discharged.
