Description

The present invention relates to a colostomy device used to close a colostomy to prevent gas, liquid or solid intestinal contents from leaking from the anus.

<Related Art> Since a colostomy, which is an artificial opening of the intestine, cannot be opened and closed at will, a bag is often used to discard the contents of the intestine. However, when going out while wearing the bag, only that portion is raised and the appearance is poor, and exercise or bathing with the bag attached is practically impossible. Therefore, it is necessary to close the opening of the colostomy in order to allow the patient who formed the colostomy to go out, exercise and bath freely, and also to close the opening of the colostomy when changing the bag or washing the bag. Various proposals have been made.

For example, an annular magnet is provided by surgery near the exit of the intestine, and the artificial anus is closed with a magnet plug fixed thereto (eg, German Patent No. 2363563), a dish made of an impermeable elastic body A plug provided with a projection in the center of the concave surface of
It consists of a belly band band and a flexible absorbent ground interposed between the plug and the band, and the closure holding force against the opening of the plug is increased by the tightening force of the torso by the band, and it leaks by any chance Even in the case, the plug is made to be absorbed by the absorbing ground (Jikken 57-44977), and the plug inserted into the colostomy is hollow, and the air is filled inside the hollow ( No. 55-49779),
Two balloons are used to inflate the balloon to close the fistula on both sides of the skin (see FIG. 56-59).
No. 001), comprising a substantially cylindrical, conical or bell-shaped flexible body of hydrophilic polyurethane foam with open cells, the body being compressed by a moisture- and / or heat-sensitive substance. And those maintained in a state (JP-A-61-170455).

FIG. 6 shows the above-mentioned example, in which the insertion portion (10
The ostomy closure device (C ') comprising 1), the exhaust portion (102), and the deodorant (103) is applied to the skin (S') around the opening of the ostomy.
The insertion part (101) is inserted into the intestinal tract (A ') connected to the colostomy.

<Problems to be Solved by the Invention> However, those using the above-mentioned magnet often require discomfort due to the action of a somewhat strong magnet when fixed, and often cause discomfort and sometimes cause necrosis of tissue. This is a problem, and the one consisting of the plug, the band, and the absorber is not only disadvantageous in terms of cost, but also when the tightening force of the band is strong, the abdominal wall is pressed and uncomfortable, and the band is fastened. If the applied force is weak, the contents in the intestine are likely to leak, and even if absorbed at 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 it is necessary to prepare one of these sizes, and it has a problem in that it has insufficient closing force and may fall off from the opening. Since it is necessary to determine the thickness according to the thickness of the patient's skin, it is necessary to prepare several types, and there is a disadvantage that the appearance of the swelling portion is poor. 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. Therefore, it was necessary to prepare several kinds according to the size, and it was necessary to adjust the size of the hole when using the skin barrier.

The present invention has been made in view of the above circumstances, is a so-called free size that is highly safe, has almost no leak, can be applied to any size opening of a colostomy, and has a foreign-body sensation during use. An object of the present invention is to provide a new type of ostomy closure device that does not require any treatment.

<Means for Solving the Problems> In order to solve the above-mentioned problems, the present invention is a device used for closing a colostomy to prevent gas, liquid or solid intestinal contents from leaking from the anus. (I) A sheet-like skin fixing portion having an opening at a central portion and an adhesive layer provided on one surface, and a plurality of chambers connected to each other, and a communication hole formed at a partition portion of each chamber. A fluid formed by forming a fan-shaped synthetic resin bag body connected and fixed at the base end of the bag body to the opening edge of the skin fixing portion on the side of the adhesive layer, and standing up substantially in a truncated cone shape. (II) the closing means comprising: an insertion portion which can be opened in an umbrella shape by injection of a cap; a cap mounting portion projecting from the periphery of the opening opposite to the insertion portion with respect to the fixing portion; An ostomy closure consisting of a cap attached to the cap mounting part of the tool body is adopted.

<Effect> The colostomy device of the present invention has a fan-shaped synthetic resin bag body in which a plurality of chambers are continuously provided and a communication hole is formed in a partition part of each chamber at a base end of the bag body. Since it has an insertion portion that can be expanded and opened like an umbrella by injecting a fluid, the insertion portion is connected to and fixed to the opening periphery of the skin fixing portion and is erected in a substantially cylindrical shape.
