の送気送水操作装置。[Scope of Claim for Utility Model Registration] An air and water supply pipe is installed inside the endoscope, and an air outlet is formed at the tip of the insertion section of the endoscope and an air supply provided outside the endoscope. A switching valve device is interposed in the middle of the air and water supply pipe, and the switching valve device is connected to the water supply means through the air and water supply pipe, and has an operating valve body inserted into the cylinder so as to be freely retractable. An air supply state in which air is jetted out from the jet port, a water supply state in which water is jetted out from the jet port, and a standby state in which air is leaked directly from the switching valve device to the atmosphere are controlled by the operation of the switching valve device. In the air/water supply operating device for an endoscope that can be switched, the operation valve body is located at a position opposite to an air supply port formed in the cylinder so as to send air from the cylinder to the jet port. is divided in the axial direction, and a sealing means is provided on the outer circumference of the operating valve body on both sides of the air supply port and on the dividing surface, and in a standby state, the dividing surface is connected to the sealing means. When the valve body is closed by the cylinder and placed in the air supply state, the divided portion of the operating valve body is opened, and air is sent from the inside of the cylinder to the air supply port through the gap. Air and water supply operating device for endoscopes.
