Problems solved by technology

[0005] In the structure of the above-mentioned prior art endoscope fluid switching valve, the liquid outlet of the fluid switching valve is separated from the gas outlet, and an additional three-way pipe and a one-way valve are required, the structure is complicated, and the hardware cost is increased.
And because the one-way valve may be blocked by impurities, it often needs to be cleaned, and since the one-way valve is arranged inside the operating part of the endoscope, it is very inconvenient to disassemble the operating part for cleaning

Abstract

Embodiments of the present invention provide an endoscopic fluid control valve. By having just one fluid outlet, the structure of the endoscopic fluid control valve is made simpler with interior space saving. There is no need for a one-way check valve at an operational portion of the endoscope to prevent fluid backflow, and this makes it easy to clean. An embodiment includes valve housing, valve stem, valve core, elastic component, button, first seal, second seal, third seal, fourth seal, gas inlet, fluid inlet and fluid outlet.

Description

technical field [0001] The invention relates to the fields of medicine and biotechnology, in particular to an endoscope fluid switching valve and an endoscope. Background technique [0002] Endoscopic systems are widely used in medical diagnosis. The endoscope system can observe organs and the like in the body cavity by inserting a long and thin insertion portion into the body cavity, and can perform various treatments by using a treatment tool inserted into the insertion channel as needed. The endoscope is also equipped with an air and liquid delivery device for cleaning and treating the treated part in the body cavity, or expanding the body cavity to expand the observation field of view, and can send water, medicinal liquid, air, etc. into the body cavity as needed. [0003] In the prior art, the air supply and liquid supply of the endoscope are controlled by a fluid switching valve provided on the operating part of the endoscope. The gas inlet for air supply and the liq...
