Lumen flusher

Abstract

The invention discloses a lumen flusher. The lumen flusher comprises a bottle splicing needle and a liquid outlet unit, wherein the bottle splicing needle comprises a needle head for splicing a flushing liquid bottle, a needle base which is connected at the tail end of the needle head and an output tube which is arranged at the tail end of the needle base; the needle head and the needle base are cavity structures; the cavities are connected with the output tube in a penetration mode; a liquid outlet joint is arranged at the tail end of the output tube; the liquid outlet unit is connected with the liquid outlet joint in a matched mode through a liquid inlet joint arranged at an end opening of the liquid outlet unit; the liquid flows into the liquid outlet unit through the bottle splicing needle; the liquid outlet unit is further provided with a liquid outlet for the liquid to flow out. According to the scheme adopted by the invention, the flusher is stable in flow; the liquid outlet flow can be controlled by virtue of frequency of pressing a pushing rod; the liquid outlet flow is great when the pushing rod is quickly pressed, and the liquid outlet flow is small when the pushing rod is slowly pushed. The flusher disclosed by the invention is stable in liquid flow; and the liquid outlet flow can be controlled by virtue of frequency of pressing the pushing rod; the liquid outlet flow is great when the pushing rod is quickly pressed, and the liquid outlet flow is small when the pushing rod is slowly pushed.

Description

technical field [0001] The invention relates to a medical device. More specifically, the present invention relates to a lumen irrigator. Background technique [0002] Clinically, the lens of the endoscope is easily polluted by bodily fluids during the visit in the patient’s body, resulting in unclear vision. Medical staff often need to clean it. The old method used to be to use a syringe of 50ml or more to extract normal saline for cleaning. It is inconvenient, and the liquid output of the syringe is not convenient to control the flow rate, and if continuous cleaning with a large flow rate is required, the liquid needs to be extracted repeatedly, which increases the workload of medical staff. However, the inner cavity flusher can be used continuously, and when a large flow rate is required, only the insertion needle needs to be pulled out to replace a larger-capacity liquid storage device for continuous flushing. Contents of the invention [0003] It is an object of the ...
