Method of cleaning scope end of endoscope and endoscope with scope end cleaning mechanism |
摘要 |
A method of cleaning scope end of endoscope capable of performing a painless cleaning operation as well as securing a stable direct observation condition, without relying on an operator's skill. The method includes the steps of: injecting water towards the scope end for washing out the scope end; exhaling air towards the scope end to blow away remaining drops on the scope end of the water injected at the injecting step; and inhaling as much an amount of air as exhaled at the exhaling step, slowly enough not to cause dew condensation due to an abrupt pressure decrease. An endoscope equipped with scope end cleaning mechanism performing this method is also disclosed.
