Abstract
Abstract A colon catheter for removing and collecting waste colon material through the anal canal. One end of a hollow tube is inserted into the anal canal and held therein by an expandable member and limiting elements outside of the anal opening against the perineum. An enclosed bag attached to the end of the tube to collect waste colon material may be made of plastic, may be clear and may be covered by an opaque bag having a viewing window and flaps to enclose the hollow tube after use. A side opening may be provided for introducing an enema solution. The entire colon catheter with the enclosed waste colon material is disposable as a unit.
