Abstract
In a method of cleaning an endoscope, the open end of a suction valve cylinder, arranged within a control section of the endoscope, is closed by a stop. A cap is mounted on the distal end of an insertion section so that liquid may flow between a nozzle and a suction opening which are arranged at the distal end of the insertion section. The nozzle communicates with an air supply channel and a liquid supply channel, and the suction opening communicates with a suction channel. A stop is mounted on the open end of an air/liquid supply valve cylinder arranged in the control section, and a syringe is connected to the stop. The piston of the syringe is pushed, thus supplying liquid in the cylinder of the syringe into the cylinder and discharging the liquid from the other ends of the three channels through the channels and the valve cylinders, thereby cleaning the interiors of these channels and valve cylinders with the liquid.
