Abstract
Abstract An artificial anus device consists of a device body and an excreta receptacle bag, and is fastened to the abdomen of a user with a belt. The device body is provided in its central portion with a through hole into which the excreta receptacle bag and an artificial anus are to be inserted, and on the portion thereof which is around the through hole with an abdomen pressure contacting portion of a predetermined thickness formed integrally therewith. The abdomen pressure contacting portion is provided in the outer circumferential surface of its base part with a recessed locking portion with which the excreta receptacle bag can be detachably engaged. The device body is provided in the portions thereof which are on the left and right sides of and symmetric with respect to the through hole and which are formed integrally with the abdomen pressure contacting portion with locking holes in which both end portions of the belt are locked. The excreta receptacle bag has a cylindrical bag body formed out of flexible rubber or synthetic resin and having at its open end a ring type locking portion to be engaged detachably with the recessed locking portion, and a closed end portion on the opposite side of the open end thereof, the film which constitutes the excreta receptacle bag covering the abdomen pressure contacting portion of and the inner surface of the through hole in the device body, the open end of this bag being engaged detachably with the recessed locking portion.
