Abstract
PURPOSE:To inspect easily existence of a leakage of water of a camera without a complication of a structure by pressurizing the inside of a camera set for a waterproof endoscope with a use of a cassette that jets high-pressurized gas through a valve interlocking by closing a rear cover. CONSTITUTION:A cassette 5 enclosed with high-pressurized gas is accommodated in a cassette accommodating room 2 of a camera 1 for a waterproof endoscope and when a rear cover 3 is closed, the camera 1 is blocked from water. On the other hand, in interlocking with closing of this cover 3, a valve 15 is opened, thereby allowing high-pressurized gas that is jetted from the valve 15 to fill the inside of the camera 1. Accordingly, when the camera 1 is dipped in a medical fluid in this state, due to occurrence of an air bubble of high-pressurized gas, an inspection for a leakage of water from a waterproof endoscope camera can be easily and certainly done without any invasion of a medical fluid into the camera 1 under high-pressure and without a complication of a structure.
