ARTIFICIAL SPHINCTER, ARTIFICIAL RECTUM, AND ARTIFICIAL DEFECATION APPARATUS HAVING THE SAME

摘要

There is provided an artificial sphincter, artificial rectum and an artificial defecation apparatus having the same, which can normally regulate defecation instead of a damaged artificial rectum or sphincter. The artificial sphincter includes a cylinder-shaped support that is positioned in an area where excrements in the human body are discharged, and is formed at the inside penetration hole, and a volume-conversion switch that is positioned in the penetration hole, and opens and closes the penetration hole by expansion and contraction. Here, it is preferable that the volume-conversion switch expands or contracts as the fluid flows into or out of the volume-conversion switch.
