Body cavity pressure adjusting device for endoscope

摘要

A body cavity pressure adjusting device for an endoscope (1) having a first channel (11) for receiving a medical tool therein comprises a suction tube (14), suction means (15) connected to and communicating with said suction tube (14), pressure detecting means (16) for detecting pressure inside said body cavity, pressure setting means (22) for setting a predetermined value for the body cavity pressure and suction control means (25) for controlling the operation of said suction means upon an output signal from said pressure detecting means (16) and an output signal from said pressure setting means (22), an air supply device (6) connectable to an air supply channel (8) in the endoscope (1), one end of the suction tube (14) being connected to the first channel (11), the other end of the suction tube (14) being connected to the suction means (15) and to the pressure detecting means (16) for measuring the air pressure in the body cavity through the suction tube (14) and the first channel, and indication means (23) for indicating the pressure detected by said pressure detecting means (16), wherein said indication means (23) continues to indicate the pressure value detected by said pressure detecting means (16) immediately before said suction means (15) starts sucking operation thereof.
