Method of fixing flexible hose over end piece of endoscope - has flexible hose in tube with vacuum to increase hose diameter so allowing insertion of endoscope end

摘要

The flexible hose (2) is inserted into a tube (21), with at least one open end, and whose inner diameter is greater than the outer diameter of the hose. The tube has a vacuum hole to suck the air out of the tube inner room. Through this vacuuming, the diameter of the hose is increased so the tube end (4) of the endoscope can be inserted into the hose. The vacuum is stopped so the hose returns to its original diameter and fits closely around the tube end of the endoscope thus keeping it in place. ADVANTAGE - The method simplifies the operation.
