Abstract: In an endoscope apparatus, a suction button unit (switching valve unit) includes a valve cylinder, a piston rod, a cap device and seal packing. Holes are formed in a piston chamber of the valve cylinder, including a discharge port hole, a suction port hole and an exhaust port hole. The piston chamber includes a piston slide surface and a sliding sealing surface. A passage in the piston rod connects the exhaust port hole with the suction port hole in case the piston rod is in a halfway position, and connects the suction port hole with the discharge port hole in case the piston rod is in a position of full depression. The seal packing, in the halfway position, closes the discharge port hole, and in the position of full depression, causes the discharge port hole to open. Thus, operability and washability of the suction button unit can be high.

Abstract: A side-viewing endoscope includes an elongated tube for entry in a body cavity for imaging. A wire line is contained in the elongated tube, for moving in an axial direction back and forth. A guide device is coupled with a distal end of the wire line, caused to shift between first and second positions by the wire line, for orientation in a direction crosswise to the axial direction upon being set in the second position. An input lever is disposed at a proximal end of the wire line, for moving the wire line in the axial direction. A cam mechanism is connected between the input lever and the wire line, for shifting the guide device at a first shift between the first position and an intermediate position, and shifting the guide device at a second shift smaller than the first shift between the intermediate and second positions.

Abstract: Provided are a state determination method for an endoscope pipe line, a state determination device for an endoscope pipe line, and an endoscope washing and disinfection device with which it is possible to determine whether an endoscope pipe line is in an open or blocked state with high accuracy. A state determination method for an endoscope pipe line includes a supply step of supplying a pressurized fluid into an endoscope pipe line, a change rate acquisition step of acquiring a change rate of a physical quantity of the fluid within a determination period after the supply of the fluid is stopped, and a determination step of determining whether the endoscope pipe line is in an open or blocked state based on the change rate acquired in the change rate acquisition step.
