Abstract
In a method of cleaning an endoscope, the open ends of an air/liquid supply valve cylinder and a suction valve cylinder, both provided within a control section of the endoscope, are closed by stops. The ends of an air supply channel, a liquid supply channel and a suction channel, which open to a connector mounted on the distal end of a light guide cable, are connected to a connecting tube so that liquid may flow between these ends. The other end of the suction channel opening to the distal end of an insertion section is connected to a liquid tank filled with liquid through a liquid supply tube. The tank is connected to an air pump through an air supply tube. When the pump is operated, the liquid is supplied from the other end of the suction channel and discharged from a nozzle through the three channels, valve cylinders and the connecting tube, thereby cleaning the interiors of these channels and valve cylinders with the liquid.
