DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for forcibly discharging stool which is inserted from the anus and which is not excreted in the intestine, by forcibly breaking, dividing, stirring and scraping (hereinafter simply referred to as "crushing"). . This device is particularly useful for bedridden elderly people and patients and those who do not have self-defecation.

[0002]

2. Description of the Related Art Heretofore, doctors and nurses have inserted a finger from the anus to scrape out a stool that stays in the intestine and cannot defecate, such as in a postal stool. This was troublesome. As a device for solving this problem, the present inventor has made it possible to expand and contract a petal-shaped protection body for protecting the intestinal wall at the tip of a cylindrical body inserted from the anus, and to freely rotate a crushing rotating body for crushing stool therein. We developed a defecation device installed in Japan. Thus, the stool in the intestine can be crushed, and the stool can be forcibly discharged by suction with a suction device connected to the cylinder. In this defecation device, the stool may rotate with the rotation of the crushing rotating body, and the stool may not be crushed effectively.

[0003]

The problem to be solved by the present invention is to solve these problems in the prior art, and to make it possible to easily and surely crush stool in the intestine by using an instrument without damaging the intestinal wall. An object of the present invention is to provide a defecation device.
