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

An embodiment of the invention discloses an endoscopic fluid control valve. The endoscopic fluid control valve is simple in structure and internal-space-saving by arranging only one fluid outlet, capable of preventing fluid backflow without arranging a one-way valve in an operation portion of an endoscope and easy to clean. The endoscopic fluid control valve comprises a valve cover, a valve stem, a valve element, an elastic member, buttons, a first seal ring, a second seal ring, a third seal ring, a fourth seal ring, a gas inlet, a liquid inlet and a 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...
