Title: Endoscope
Inventor: WATANABE ISAO
IPC: G02B23/24
Filed: 1992-10-29
Abstract: PURPOSE:To avoid the fogging phenomenon of an observation window due to bedewing by disposing a feedwater pipe near a heating element which generates predetermined waste heat. CONSTITUTION:This endoscope includes an air and water feed pump 1 which can feed air and water and is e.g. a low pressure pump whose temperature is raised to 70 deg.C under maximum load and to around 40 deg.C in normal use. The endoscope is connected to a container 2 via a connection pipe 11 and a feedwater pipe 3 and an air feed pipe 4 are connected to the respective portions of the container 2. The feedwater pipe 3 is wound near the air and water feed pipe 1 serving as a heating element which generates predetermined waste heat. Therefore, water flowing inside the feedwater pipe 3 absorbs the generated heat of the air and water feed pump 1 through the wall of the feedwater tube 3 and is heated to the vicinity of the internal body temperature. Then the water is ejected toward an observation window from a waterfeed nozzle provided at the end of the scope to wash the observation window. Since the water ejected is almost at the internal body temperature, the observation window is heated to almost the same temperature, so the observation window is not bedewed with vapor in the selom.
