DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a colostomy device for closing a colostomy to prevent leakage of liquid or solid intestinal contents from the anus.

[0002]

2. Description of the Related Art Bags are often used to discard the contents of the intestine because the opening and closing of the colostomy, which is the artificial opening of the intestine, cannot be controlled by intention. However, when going out with the bag worn, only that portion is raised and the appearance is poor, and exercise or bathing with the bag attached is substantially impossible.
Therefore, in order to allow a patient having a colostomy to freely go out, exercise and bathe, various colostomy means have been proposed for the purpose of closing the colostrum opening.

For example, an annular magnet is provided by surgery near an intestinal outlet, and an artificial anus is closed with a magnet plug fixed to the annular magnet (West German Patent No. 2363563).
No.), a plug made of an impervious elastic body with a projection at the center of the concave surface, a belly band band, and a flexible absorbent ground interposed between the plug and the band The closure force of the opening of the plug body is increased by the tightening force of the body by the body, and even in case of leakage, it is absorbed at the absorption site (Jikken Sho 57-449).
No. 77), a plug with a hollow portion inserted into the colostomy, one filled with air inside the hollow portion (Japanese Utility Model Publication No. 55-49779). The balloon is inflated with two balloons. To close the fistula on both sides of the skin (Japanese Utility Model Publication No. 56-59001), to provide a tubular plug with a balloon covering almost the entirety thereof (U.S. Pat. No. 4,241,735), Provided with an expanding balloon (JP-A-58-1090)
No. 50), consisting of a substantially cylindrical, conical or bell-shaped flexible body of open-celled hydrophilic polyurethane foam, the body being compressed by a moisture- and / or heat-sensitive substance. And those maintained in a state (JP-A-61-170455).

FIG. 4 shows the above example, in which an ostomy closure (C ') comprising an insertion portion (101), an exhaust portion (102), and a deodorant (103) is used to open the ostomy. It is attached to a flange (f) fixed to the peripheral skin (S '), and the insertion part (101) is inserted into the intestinal tract (A') connected to the colostomy.

[0005]

However, the method using the above-mentioned magnet requires a strong action of the magnet for fixing, which often causes discomfort and sometimes causes necrosis of tissue. The plug body, the band body, and the absorbent body are not only disadvantageous in terms of cost, but also when the tightening force of the band body is strong, the abdominal wall is pressed and uncomfortable, and the band body is tightened. If the power is weak, the contents in the intestine are likely to leak, and even if absorbed in the absorption site, discomfort cannot be avoided. Further, the plug body hardly irritates the inner wall of the colostomy due to compression, and does not damage the mucous membrane of the colostomy or feel an unpleasant foreign body sensation. This is inconvenient because such a size must be prepared, and it has a problem that it has a poor closing force and may fall off from the opening. Another 2
For those with two balloons, it is necessary to determine the distance between balloons according to the thickness of the patient's skin, so it is necessary to prepare several types, and the appearance is bad because the wearing part swells Has disadvantages. When the outer surface of the plug is covered with a balloon, various types of balloons are inserted into the colostomy to close it, but since none of the balloons have a support mechanism, they are inserted into the intestinal tract. There is a risk of entangled bowel obstruction. In addition, no measures have been taken against gas emission. The plug device provided with a balloon that expands forward has a support device operatively buried in the abdominal cavity, and the intestinal tract is sandwiched between the support device and the balloon inserted into the colostomy. Embedding the support in the abdominal cavity involves pain and a foreign body sensation, and in some cases, causes many new problems such as inflammation such as peritonitis. Also,
No effort has been made on gas. The closing means formed by compression-molding the polyurethane foam is used by attaching it to a skin barrier. However, the closing means has a foreign body feeling during use because of the plug shape, and the size of the opening is also large. It is necessary to prepare several types according to the requirements.

The present invention has been made in view of the above circumstances, and is a so-called adjustable that is highly safe, has almost no leakage, and can be applied to artificial anus of various shapes, and has a foreign body sensation during use. It is an object of the present invention to provide a new type of colostomy device with a reduced number of cases.
