## Abstract

An indwelling evacuator for feces, a stranding cage is disposed in a cylindrical main body, and a soft shaft is connected to the rear end of the stranding cage. Petaloid movable blades are hingedly connected to the front end of the cylindrical main body, and are in the shape of a bud when the petaloid movable blades are closed. A blocking ring is disposed on the outer wall of the cylindrical main body. A sliding ring member is disposed in the cylindrical main body to push the movable blades open to form an open space in the shape of a flower. The rear portion of the cylindrical main body is downward connected to a feces discharge hose. In use, the bud portion in the front end is inserted into the anus, and the blocking ring limits the insertion depth.
