Abstract

The invention discloses a suction valve. The suction valve comprises a valve body, an elastic piece, a plunger and a sealing piece; the elastic piece is arranged on the upper portion of the valve body, and the top of the plunger is installed on the elastic piece; a first communication port and a second communication port are formed in the valve body and used for being communicated with the interior of the valve body, the sealing piece is installed on a communication area between the first communication port and the second communication port, and a through hole is formed in the sealing piece; the plunger comprises a rod body and a sealing block; the sealing block is arranged at the tail part of the rod body; the rod body is partially contained in the through hole, and the sealing block penetrates through the through hole and can abut against the wall face of the sealing piece; and the second communication port is formed in the side wall of the valve body. The second communication port is formed in the side wall of the valve body, and the problems that when the plunger is pressed, the distance between the sealing block at the end of the plunger and a hydrops suction port is shortened, the circulation sectional area of the position is reduced, and hydrops circulation resistance is increased are solved.

Description

Technical field [0001] The present invention relates to the technical field of medical devices, in particular to a suction valve and an endoscope. Background technique [0002] When using the endoscope, the medical staff observe the diseased part through the endoscope, and at the same time can suck the fluid in the patient through the suction valve, eliminate the interference of the fluid during the inspection and treatment process, and ensure the observation field. [0003] In the prior art, the suction valve of the endoscope is composed of a suction valve housing, a suction valve inner housing, a seal, a plunger and other parts. There are many parts and the assembly is complicated. In particular, the suction valve body includes an outer housing and an inner housing. Both the inner shell and the outer shell are provided with holes. When the two are assembled, the holes between the two need to be accurately positioned and aligned to ensure smooth extraction of the patient’s fluid; ...
