ABSTRACT:
A coupler structure for tube units of endoscopes functions to prevent a liquid, etc. remaining in aspiration tubes from adhering or penetrating to or into other tubes, and avoid increasing surplus cleaning and sterilizing works. Aspiration tubes have protruding lengths longer than those of air feeding tubes and water feeding tubes in couplers of an endoscope which is configured to couple a tube unit with a control section by way of a faucet joint and control rings. All these tubes are arranged so as to protrude from wall surfaces. When a positioning key and a key groove which also serve for restricting rotation are to be disposed, this key is configured longer than the aspiration tubes. This coupler structure allows the air feeding tube and the water feeding tube to have been already pulled out when the aspiration tube is pulled out, thereby preventing soiled water, etc. flowing out of the aspiration tubes from adhering to or penetrating into the air feeding tubes and water feeding tubes. The protruding structure also serves for preventing soiled water, etc. from flowing into the tubes.
