Abstract
In a method of cleaning an endoscope, a stop having a communication path is mounted on the open ends of an air/liquid supply valve cylinder and a suction valve cylinder of the endoscope so that liquid may flow between the valve cylinders through the communication path. One end of a suction channel, which opens to the distal end of an insertion section of the endoscope, is connected to a liquid tank through a liquid supply tube. An air supply pump is connected to the tank. The pump is operated in this state and supplies the liquid held in the tank to the one end of the suction channel. The liquid supplied to the one end of the suction channel is discharged from a nozzle at the distal end of the insertion section and the other ends of the suction channel, an air supply channel and a liquid supply channel, which open to a connector mounted on a light guide of the endoscope, through the three channels and the valve cylinders, thereby cleaning the interior of these channels and valve cylinders.
