摘要： PROBLEM TO BE SOLVED: To provide an internal pressure regulating device for an endoscope which obviates the occurrence, or the like, of trouble, such as a failure, by biting of an outer cover rubber tube of a curved part between nodal rings on its inner side by constituting the device in such a manner that air of the quantity sufficient for approximating the internal pressure of the endoscope to atmospheric pressure is surely fed into the endoscope when removing a valve open adapter from a check valve. SOLUTION: This internal pressure regulating device is provided with a pressure sensitive stopper 50 which regulates the movement of the valve open adapter 30 forward of the state that the check valve 10 is forcibly opened in removing the valve open adapter 30 when the pressure on the outside of the endoscope is higher by a specified pressure than the internal pressure and which retreats the adapter from the regulation position when the pressure on the outside of the endoscope is not higher by the specified pressure or above than the internal pressure.

摘要： PROBLEM TO BE SOLVED: To prevent high temperature steam from entering an endoscope when a damage from outside through inside is made on the outer shell of the endoscope, so that troubles of optical components inside the endoscope can be prevented beforehand. SOLUTION: This autoclave has endoscope air sucking means 2 and 12, a pressure detecting means 4 and a safety control means 3. The endoscope air sucking means 2, 12 are to suck and exhaust air from an endoscope 50 interlocking with sterilizing tank air sucking means 2 and 11 which suck and exhaust air from a sterilizing tank 1. The pressure detecting means 4 is to detect the pressure inside the endoscope 50. And the safety control means 3 is to stop the motion of a steam filling means 13 when the pressure detected by the pressure detecting means 4 rises after the steam filling means 13 is started.

摘要： PROBLEM TO BE SOLVED: To make the illuminating light efficiently incident on a light guide with a small loss by using an electric lamp having a lens with the lens formed on the tip as a light source to supply the illuminating light to the light guide to transmit the illuminating light, and arranging a lens surface of the electric lamp in close contact on an incident end surface of the light guide. SOLUTION: In an illuminating light guide fiber bundle (hereinafter referred to as an LG bundle) 9 to transmit the illuminating light to illuminate an object in an operation part 2 of an endoscope, an incident end part is arranged in an operation mechanism part 5. The operation mechanism part 5 also has a power source unit 30 enclosing a light source lamp 32 to radiate the illuminating light supplied to the LG bundle 9 and a battery 100 being an illuminating power source. In this case, an incident end part of the LG bundle 9 is fastened/fixed in the outward direction by a screw to a bottom part central axis position of a unit connecting base 27, and a convex lens part 32b of the light source lamp 32 being a miniature lamp having a lens is arranged in close contact so as to be opposed to its incident end surface. Therefore, incident efficiency of the illuminating light can be enhanced.
