Abstract
The utility model discloses a water injection device used for colonoscope operation and relates to a water injection appliance used for the colonoscope operation. The water injection device used for the colonoscope operation solves the problem that during an existing colonoscope operation process, an injector with a volume of 50 ml is adopted to inject water into an enteric cavity, and due to the small volume and small pressure of the injector, continuous performance of the operation is poor, and colonoscope inserting requirements of doctors can not be met. An inner tube is arranged in a water storage bottle, wherein the lower end of a lower tube is located at the bottom of the water storage bottle, the upper end of an upper tube is located outside an bottle opening of the water storage bottle, a water inlet valve is arranged at a position of a taper tube in the inner tube, and a spring is arranged in the upper tube. A press bar water through hole is formed inside a press bar, and a press handle water through hole communicated with the press bar water through hole is formed inside a press handle. A rubber ring is arranged in the upper end of the upper tube, wherein the lower end of the press bar is arranged in the rubber ring. A water storage bottle cover is in threaded connection with the bottle opening of the water storage bottle 1. An inner tube cover is in threaded connection with the upper end of the upper tube. An input end of a connection tube is connected with the press handle water through hole. A tee joint is installed on the connection tube. The water injection device is used for the colonoscope operation.
