Apparatus for draining a conduit

摘要

Apparatus for draining a conduit such as the colon of an animal while preventing the spread of contamination from the conduit. The apparatus comprises two tubes. The first tube, which is open at both ends, is designed to be slipped onto the tied and cut portion of, for example, a colon and secured to it with the tied and cut end of the colon protruding from the tube. The second tube has an open end that is designed to be secured to the first tube around the protruding portion of the colon. In the second tube, there is a drain and means for cutting open the tied and cut portion of the colon. Before the colon is opened, a seal must be provided between the colon and the tubes to prevent the spread of contamination from the opened colon. To this end, an annular chamber is provided in the region where the two tubes are connected. When suction is applied to this chamber, the sidewalls of the colon are drawn into the chamber so that they may be tightly secured between the end of the first tube and the opposing end of the second tube.
