[0004]

In the conventional suction-type excrement disposal apparatus, urine or stool excreted into a cup through a pipe from a urine-collecting stool cup applied to a crotch of a human body is sucked by vacuum suction. Since the urine and feces are collected by sucking into the waste tank, bedridden elderly people and seriously ill patients using the cup are strongly suction-pressed to the crotch where the cup was applied during vacuum suction. As a result, the buttocks and the like are tightened around the periphery of the cup, so that user discomfort is inevitable and the burden on the cup is large. The present invention has been made in view of the above points, and eliminates a strong pressure on a cup between crotch due to vacuum when excreted urine or stool is sucked by vacuum suction from a cup applied to the crotch. The present invention provides a vacuum suction type excrement disposal device capable of relieving the pressure at the periphery of the cup, gentle to the skin, eliminating discomfort of the user, and reducing the burden on the cup even if the suction force is strong. Aim.
