BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an ostomy closure device used to close an ostomy and prevent leakage of liquid or solid intestinal contents from the anus.

0002

2. Description of the Related Art Since the opening and closing of an artificial anus, which is an artificial opening in the intestine, cannot be controlled voluntarily, bags are often used to dispose of the contents of the intestines. However, if you go out with the bag on, only that part will bulge out, making it unsightly, and it is virtually impossible to exercise or take a bath with the bag on. In order to allow patients with a colostomy to freely go out, exercise, and take a bath, various colostomy closing means have been proposed for the purpose of closing the opening of the colostomy.

For example, ① a ring-shaped magnet is surgically placed near the exit of the intestine, and a magnetic plug fixed to the ring-shaped magnet is used to close the colostomy (West German Patent No. 2363563);
(e.g., No. 1, etc.), ■ Consisting of a plug body with a protrusion at the center of the concave surface of a dish made of impermeable elastic material, a belly band body, and a flexible absorbent fabric interposed between the plug body and the band body, The tightening force of the body part by the band body increases the closing force of the stopper against the opening, and even if leakage occurs, it will be absorbed by the absorbent material (Utility Model Publication No. 57-449)
77), ■It is a plug with a hollow part that is inserted into the colostomy, and the hollow part is filled with air (Utility Model Publication No. 55-49779), ■It is equipped with two balloons, and the balloon (U.S. Patent Publication No. 56-59001), (U.S. Pat. No. 4,241,735), (U.S. Pat. No. 4,241,735), (U.S. Pat. No. 4,241,735), A device equipped with a balloon that expands forward (Japanese Patent Laid-Open No. 58-1090)
No. 50), ■ Consisting of a substantially cylindrical, conical or bell-shaped flexible body made of hydrophilic polyurethane foam having open cells, which body is compressed by a moisture-sensitive and/or heat-sensitive substance. (Japanese Unexamined Patent Publication No. 170455/1983), etc.

The one shown in FIG. 4 is an example of the above-mentioned item (2), in which a colostomy obturator (C') consisting of an insertion part (101), an exhaust part (102), and a deodorant (103) is inserted into the colostomy. It is attached to a flange (f) fixed to the skin (S') around the opening, and the insertion part (101) connects to the intestinal tract (A) that connects to the colostomy.
') is inserted within.

[Problem to be solved by the invention] However, the above
Those using magnets are problematic because they require strong magnetic action for fixation, which often causes discomfort, and can sometimes cause tissue necrosis. Absorbent materials are not only disadvantageous in terms of cost, but if the band's tightening force is strong, the abdominal wall will be compressed and uncomfortable, and if the band's tightening force is weak, intestinal contents may leak. This is likely to occur, and even if you absorb it with absorbent fabric, you will not be able to avoid the discomfort. Furthermore, the plug shown in ■ hardly irritates the inner wall of the colostomy due to pressure, and does not damage the mucous membrane of the colostomy or cause an unpleasant foreign body sensation, but it may vary depending on the size of the colostomy. This is inconvenient because different sizes must be prepared, and there is also a problem in that it lacks sufficient closing force and may fall out of the opening. Also ■2
For those with two balloons, the spacing between the balloons needs to be determined according to the thickness of the patient's skin, so several types of balloons need to be prepared, and the part to be worn bulges out, making it unsightly. It has its drawbacks. The outer surface of the plug covered with a balloon is intended to be closed by inserting various types of balloons into the ostomy, but none of the balloons have a support mechanism, so they cannot be used inside the intestinal tract. There is a risk that it may enter the body and cause intestinal obstruction. Also, no measures have been taken to prevent gas emissions. In the plug device (2) with a balloon that expands forward, a support device is surgically implanted into the abdominal cavity, and the intestinal tract is pinched between the balloon inserted into the colostomy and the support device. Implanting a (supporting device) in the abdominal cavity is problematic because it causes pain and a feeling of a foreign body, and in some cases can cause many new problems such as inflammation such as peritonitis. Furthermore, no efforts have been made regarding gas. The closing means made by compression molding polyurethane foam (■) is used by attaching it to the skin barrier, but because it is in the shape of a plug, it feels like a foreign body during use, and the opening is large. It is necessary to prepare several types according to the situation.

The present invention was made in view of the above circumstances, and is highly safe, has almost no leakage, is so-called adjustable and can be applied to various shapes of artificial anus, and does not cause a foreign body sensation during use. The purpose is to provide a new type of colostomy closure device with less

[0007]

[Means for Solving the Problems] In order to solve the above-mentioned problems, the present invention provides a sheet-like flange having an opening in the center and an adhesive layer on the back surface, and a sheet-like flange having an opening in the center and an adhesive layer on the back surface. It consists of a cap mounting part, a cap attached to the cap mounting part, and a tube for insertion into the body with both ends closed and whose upper end is fixed to the cap, and the tube has a tube near its tip. and a side hole for degassing on the cap side of the flange, a balloon between these side holes, and a balloon inflation tube connected to the balloon. There is.

[0008]

[Operation] Since the colostomy closure device of the present invention is constructed as described above, the plug body (internally inserted tube) is fixed in a pinched manner between the cap part outside the body and the balloon inside the body, with the abdominal wall in between. be done. In addition, the ostomy is closed by the cap portion and the balloon portion inflated with air or water. Furthermore, the cap is configured to have gas permeability and deodorizing properties, for example, the top surface of the cap is formed to allow gas to pass through, and a gas permeable partition is provided on the bottom surface of the cap to form a cavity. If this cavity is densely packed with a deodorizing material, such as a carbon filter, the gas generated in the intestinal tract will enter the inner cavity of the tube through the side hole on the distal end of the tube, and the side hole on the cap side. The odor enters the space on the underside of the cap, is deodorized by the deodorizing material of the cap, and is expelled, so it is expelled from the body without causing discomfort due to bad odor.

FIG. 1 is a partially cutaway front view of a colostomy obturator according to an embodiment of the present invention, taken in a cross section passing through the longitudinal axis and the central axis of the balloon inflation tube, and FIG. 2 is an exploded view of the colostomy obturator of FIG. 1. FIG. 3 is a cross-sectional view of a main part of the artificial anus, and FIG. 3 is a diagram showing the state in which the artificial anus closure device of FIG.

As shown in FIGS. 1 and 2, the colostomy closure device C of the present invention includes a sheet-like flange 1 and a cap mounting portion 2.
, a cap 3, and a tube 4 for insertion into the body. The intracorporeal insertion tube 4 is provided with a balloon 5, side holes 6, 7, and a balloon inflation tube 8, and as shown in FIG. 3, the balloon is inflated with liquid or gas introduced from the balloon inflation tube 8. 5 and cap 3
The artificial anus is partially closed. In the colostomy closure device C configured as shown in FIG. 3, the gas generated in the intestinal tract is discharged from the body without causing any discomfort due to the deodorizing material 9 placed inside the cap 3. There is. Each part will be explained in detail below.

The flange 1 is a part for fixing the colostomy closure device C to the periphery of the opening of the colostomy, has an opening 10 in its center, and has an adhesive layer (not shown) on the back surface. . The flange 1 is generally formed of a thin sheet in the shape of a brim, and a cap mounting portion 2 is provided on the surface of the flange 1 protruding outwardly from the opening 10 and concentrically with the opening 10. The central opening 10 has a slightly larger diameter than the opening of a normal colostomy, and when in use, the opening end of the colostomy protrudes from this part as shown in Figure 3, and the colostomy is inserted into the body. The fitting tube 4 is inserted and fixed. The material for forming the flange 1 is generally polyethylene or ethylene.
So-called hard rubber is made by blending a large amount of filler or synthetic resin with soft synthetic resins such as vinyl acetate copolymer and soft polyvinyl chloride, or synthetic rubbers such as butadiene rubber, styrene-butadiene rubber, and butyl rubber, and then vulcanizing the mixture. used. Although the thickness of the flange 1 is not particularly limited, it is generally 0.7 to 1.3 mm. Note that the flange 1 and the cap mounting portion 2 may be formed integrally.

The cap attachment part 2 is a part to which a cap 3 is attached for closing the opening of the colostomy closure device C, and is provided so as to protrude from the surface of the flange 1 and surround the opening 10. 11 is an annular projection for attaching the cap 3, and an annular groove 1 provided in the cap 3, which will be described later.
It is formed to fit with 2. Cap attachment part 2
The material for forming the flange 1 is not particularly limited as long as it is a synthetic resin, but the same material as the flange 1 may be used, and in this case, it can be formed integrally with the flange 1.

The cap 3 is attached to the cap attachment part 2 to prevent leakage of intestinal contents, and is generally made of soft synthetic resin such as polyethylene, soft polyvinyl chloride,
It is formed of polyester, etc., or a rubber-like elastic body such as natural rubber, butadiene rubber, silicone rubber, isoprene rubber, etc. An annular groove 12 is formed in the cap 3, and an annular protrusion 1 of the cap mounting portion 2 is formed in this portion.
It is designed to fit with 1. The cap 3 may be formed to be liquid-impermeable and gas-permeable for venting gas, and in this case, it is necessary to take measures to remove the bad odor caused by the gas generated in the intestinal tract. As a specific example of gas release, as shown in FIG. 3, the top surface of the cap 3 is formed to allow gas to pass therethrough, and a gas-permeable partition wall 13 is provided inside the cap 3 to form a cavity. There is a configuration in which this cavity is filled with a deodorizing material 9. The structure may be such that a carbon filter is densely packed in the cavity as a deodorizing material. The gas permeability of the top surface of the cap 3 is determined by a hole (not shown) of an appropriate size that does not allow the deodorizing material to pass through the top surface.
This can be achieved by providing a filter (not shown) or forming at least a portion of the top surface with a filter (not shown). The partition wall 13 is usually formed of a material that does not allow liquid to pass through, such as a hydrophobic membrane filter, but in the case of a structure in which carbon filters made of hydrophobic fibers are densely packed, it is made of a material large enough to allow liquid to pass through. It may also be a partition wall with a hole or the like. In addition to the carbon filters mentioned above, deodorizing materials such as activated carbon, silica gel, activated clay, ascorbic acid-iron salts, or deodorizing fibers containing iron and phthalocyanine compounds can be used as deodorizing materials, and as hydrophobic membrane filters, polyethylene and Those made of synthetic resins such as polypropylene and polytetrafluoroethylene can be used.

The internal insertion tube 4 is a part that is inserted into the colostomy during use, and its proximal end (upper end part) is fixed to the cap 3. Side holes 6 and 7 for gas venting, respectively
A balloon 5 is formed between the side holes 6 and 7 and is inflated by injection of a fluid such as air or water. The proximal end of the intracorporeal tube 4 is generally closed, and the balloon inflation tube 8 passes through this proximal end and is connected to the balloon 5. The tube 4 to be inserted into the body is generally made of soft synthetic resin such as polyvinyl chloride, polyethylene, or polyurethane, butadiene rubber, isoprene rubber, urethane rubber, silicone rubber, etc. in order to relieve pressure on the intestinal tract, but is not limited thereto. It is made of rubber-like elastic material.

The balloon 5 is inflated with air or the like injected from the balloon inflation tube 8, expands the intestinal wall, fixes the tube 4 to the intestinal wall, and closes the intestinal canal in a fluid-tight manner. It is provided between side holes 6 and 7. The attachment position of the balloon 5 to the tube 4 is preferably a position close to the side hole 6 on the distal end side, since the position where the balloon 5 is fixed in the intestinal tract is determined and the tube 4 can be shortened. The balloon 5 is made of a rubber-like elastic material, such as natural rubber, isoprene rubber, silicone rubber, or urethane rubber, and is usually formed into a spherical, tire-like, funnel-like, or other shape.

The balloon inflation tube 8 is a part that connects a means for injecting fluid such as air or hot water into the balloon 5 to inflate it, and is normally attached airtightly through the wall of the cap 3, with one end is formed in a fluid inlet (14), and the other end is connected to the balloon 5 in communication. The balloon inflation tube 8 generally extends from the proximal end of the body-insertable tube 4 through its lumen, either directly or via a lumen 15 formed in the inner wall of the tube 4 that communicates with the lumen of the balloon 5. will be communicated with. The fluid inlet 14 may be directly connected to the lumen 15. The exposed position of the balloon inflation tube 8 from the cap 3 is not necessarily limited to the vicinity of the center of the cap 3, and may be on the side wall of the cap 3, but the fluid inlet 14 should not protrude to the outside of the cap 3. Preferably. The fluid inlet 14 is generally made of a soft synthetic resin such as polyethylene or soft polyvinyl chloride, and is provided with a valve 16 inside. This valve 16
It is preferable that the amount of fluid can be adjusted freely.
For example, there is a valve that allows fluid to be taken in and taken out, as shown in Japanese Unexamined Patent Publication No. 2-134165.

Next, a method of using the colostomy closure device of the present invention will be explained with reference to FIG. First, the flange 1 integrated with the cap attachment part 2 is attached so that its opening 10 surrounds the patient's colostomy S, and then the internal insertion tube 4 fixed to the cap 3 is inserted into the colostomy S. . Then, the cap 3 is attached to the cap attachment part 2 to close the artificial anus S, and then, for example, air is injected from the fluid inlet 14 of the balloon inflation tube 8 to inflate the balloon 5. If necessary, the degree of inflation of the balloon 5 is adjusted by letting air in and out of the balloon 5, thereby firmly fixing the colostomy obturator C in a state where the patient's pain and discomfort are alleviated as much as possible.

[0018]

[Effects of the Invention] As can be seen from the above explanation, in the colostomy closure device of the present invention, the tube to be inserted into the body is fixed in a pincer manner between the cap outside the body and the balloon inside the body, with the abdominal wall in between. , the colostomy obturator will not fall out. Furthermore, since the cap and balloon close the colostomy, the contents will not leak. Furthermore, the cap is gas permeable, and the gas permeable part of the cap is filled with deodorizer, so gas generated in the intestines is constantly expelled from the body without causing discomfort due to odor. You will not experience any discomfort due to abdominal distension due to gas.
