Abstract
An endoscope comprising one or plural fluid inlets at the grip end of the endoscope or at the feeding pipe which contains an air-feeding pipe and a light-transmitting optical fiber. For washing and sterilization of endoscope which does not have a water-proof structure, compressed air or liquid is infused through the fluid inlet, raising the inner pressure of the endoscope to prevent the permeation of the cleanser and disinfectant into the innerside of the endoscope. For washing and sterilization of an endoscope which has a water-proof structure, the compressed air or the liquid is infused through the fluid inlet to detect a pin hole on the surface of a flexible sheath.
