Abstract
Abstract @ A device for cleaning an endoscope includes a communication member (86) which is inserted into an air and water supply cylinder of the endoscope after removing a changeover piston from the cylinder. The communication member (86) is movable between first and second positions and has a through-hole (99). Through the through-hole (99), the upper side portion (6a) of a water supply passage is communicated with the lower side portion (5b) of an air supply passage when the communication member (86) is in the first position, and the upper side portion (5a) of the air supply passage is communicated with the lower side portion (5b) of the air supply passage when the communication member (86) is in the second position.
