Anus praeter device for closing artificial intestinal orifice - using system of magnets and having valved borehole for gases

摘要

The anus praeter device closes an artificial bowel outlet orifice using a permanent magnet in the bowel outlet with implanted axially magnetised additional magnetic parts. There is a correspondingly magnetised annular system in a sealing cap with a centrally positioned magnet core in a sleeve. The magnet core and the sleeve encompassing it have an axial bore hole permitting gases to escape and/or rinsing of the system even when the seal is in position. A ball valve or mechanically sliding valve isused to close the bore hole in the core and sleeve, or another magnet can be used.
