Abstract
In a method of cleaning an endoscope, a stop is mounted on the open end of an air/liquid supply valve cylinder thereby closing the open end. A liquid tank is connected through a liquid supply tube to a first air supply port which opens to a connector of the endoscope and communicates with one end of an air supply channel. A connecting cap is attached to the connector so that a second air supply port communicating the air supply channel and a liquid supply port communicating with a liquid supply channel communicate with each other. An air supply pump is connected to the liquid tank. The pump is operated under this condition and supplies the liquid in the liquid tank to the first air supply port. The liquid supplied to the first air supply port is discharged from a nozzle communicating with the other ends of the air and liquid supply channels through these channels and the air/liquid supply valve cylinder, thereby cleaning the interior of these channels and the cylinder.
