Indwelling Evacuator for Feces

An indwelling evacuator for feces, comprising:

• a cylindrical main body;
• a stranding cage;
• wherein the stranding cage is disposed in the cylindrical main body, wherein a rear end of the stranding cage penetrates through a rear wall of the cylindrical main body,
• a soft shaft joint is disposed at the rear end of a stranding cage, the soft shaft joint is connected to an end of a soft shaft, and the other end of the soft shaft is connected to a driving mechanism away from an anus;
• a sliding ring member is disposed in the cylindrical main body;
• a blocking ring is disposed on a front portion of an outer wall of the cylindrical main body;
• a plurality of petaloid movable blades are disposed at a front end of the cylindrical main body, and the plurality of petaloid movable blades are hingedly connected to the front end of the cylindrical main body;
• the petaloid movable blades are in the shape of a bud when the petaloid movable blades are closed;
• the sliding ring member contacts with a rear end of the petaloid movable blades when the sliding ring member is in a forward position;
• contact surfaces between the sliding ring member and the petaloid movable blades are complementary slopes or curve surfaces, and the petaloid movable blades are openable to form a shape of open flower;
• an inner surface of opened petaloid movable blades forms an open space in the shape of an open flower, a front portion of the stranding cage is located in the open space;
• the surface, being toward a rectum wall, of the shape of the open flower forms a hemisphere curve surface having an outer diameter greater than an outer diameter of the cylindrical main body;
• the hemisphere curve surface and the blocking ring form a middle space around the cylindrical main body, clapping an anus sphincter from inside and outside of the anus;
• a rear portion of the cylindrical main body is connected to a feces discharge hose;
• the petaloid movable blades are of mesh structure;
• the sliding ring member is disposed in the cylindrical main body, and a pulling stick is disposed on an outer wall of the sliding ring member, and the pulling stick penetrates through the cylindrical main body and is fixed by a fastener;
• the liquid pipe is disposed between the cylindrical main body and the sliding member, a rear end of the liquid pipe penetrates through the cylindrical main body, a front end of the liquid pipe has an opening in a cavity of the open petaloid movable blades, and the rear end of the liquid pipe is connected to a liquid inlet.
