Channeled endoscope cover fitted type endoscope
 A cover-fit endoscope can be used while being covered with a cover so that it is watertight. An appliance channel is extended through the cover and an appliance insertion inlet of the channel is open. This opening of the appliance insertion inlet is provided with an integral appliance plug. It is therefore possible to prevent the contaminated appliance plug from being fitted to the sterilized cover by mistake, and also to prevent leakage of the body fluids. Thus, the cover-fit endoscope is kept from contamination. The cover and the appliance plug are both discarded after use. The need for washing and disinfecting the cover-fit endoscope is eliminated, and use of the sterilized appliance plug is always ensured to reduce a fear of infection.
