Field of the Invention The present invention relates to an endoscope conduit control device, and more particularly to a suction pipe for supplying air / water to a distal end portion through an air / water supply pipe, or for sucking the contents of an object to be observed from the distal end portion.

Description of the Related Art In an endoscope, air or water (physiological saline, etc.) is jetted from an air / water supply nozzle at a distal end toward an observation window or the like, and observation is performed through a forceps port at the distal end. It is possible to suck contents and the like in the body. For this purpose, an air supply pipe, a water supply pipe, a suction pipe, and the like are provided in the endoscope, and a mechanical (mechanical) operation valve or an electric valve for controlling the flow of these pipes is provided to the endoscope operation unit. An operation switch is provided.

い難いという不都合もある。That is, conventionally, the flow of an endoscope channel is controlled by using a mechanical operation valve, or by using an electromagnetic valve unit and an operation switch. When the above-mentioned mechanical operation valve is used, the suction pipe is opened and closed by raising and lowering a piston in which one communication path is formed in suction, and an air supply path and a water supply path including, for example, an open air path in air supply / water supply. The air supply is performed by closing the open-to-atmosphere path of the piston in which the two communication passages are formed, and the water supply is performed by pushing down the piston. In the case of this mechanically operated valve, there is an advantage that the flow rate can be finely adjusted (analog adjustment) by adjusting the amount of pushing of the piston with a finger, but there is also an inconvenience that it is difficult to clean the valve portion having the movable piston. is there.

が向上するという利点がある。On the other hand, the electromagnetic valve unit is provided separately from the endoscope, and an electric operation switch for opening and closing the electromagnetic valve in the electromagnetic valve unit is arranged in an operation section. The suction operation is performed by opening and closing the corresponding electromagnetic valve by turning on and off, and in the air supply / water supply, the air supply operation is performed by, for example, opening and closing the corresponding electromagnetic valve by pressing the first stage of the air supply / water supply switch. The water supply operation is performed by the second-stage pressing operation. When this electromagnetic valve unit is used, there is an advantage that the valve portion is easily cleaned and the cleaning performance is improved because a movable piston is not used unlike the mechanical operation valve.
