Problems solved by technology

[0002] During the use of the existing air source terminal, especially the suction terminal, the stainless steel one-way valve spring in the terminal will be damaged due to direct contact with the one-way valve spring by the patient's pus, phlegm, blood and hospital special cleaning chemicals. Breakage, resulting in a small amount of air output at the air source terminal, or even failure to output air, which not only affects the use, but also leads to the possibility of doctor-patient disputes, and increases the maintenance cost

Abstract

The invention relates to a vacuum aspiration air source terminal, which comprises a valve base. A positioning inserting sleeve is fixed on the valve base, a color ring is fixed on the positioning inserting sleeve, and a button press ring is fixed outside the color ring; a valve spool is further disposed in the valve base, a valve spool sleeve is further arranged on the valve spool, and the valve spool contacts with a plug. The vacuum aspiration air source terminal is characterized in that an air inlet hole is arranged on a side wall of the valve base and is connected with a pipe; and a valve seat spring chamber is further arranged in a cavity of the valve base, a valve spool spring chamber is disposed at one end of the valve spool, and a valve spool spring is disposed between the valve base and the valve spool, and is placed in the valve seat spring chamber and the valve spool spring chamber. The vacuum aspiration air source terminal is simple in structure and convenient in use, by the aid of the design of a sealing type structure, the one-way valve spring is completely isolated from pollutants and is not easy to be corroded, so that the service life of the air source terminal is prolonged, and normal use of the vacuum aspiration air source terminal for medical staff can be ensured.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a negative pressure suction air source terminal. Background technique [0002] During the use of the existing air source terminal, especially the suction terminal, the stainless steel one-way valve spring in the terminal will be damaged due to direct contact with the one-way valve spring by the patient's pus, phlegm, blood and hospital special cleaning chemicals. Breakage, resulting in a small amount of air output at the air source terminal, or even failure to output air, which not only affects the use, but also leads to the possibility of doctor-patient disputes, and increases the maintenance cost. [0003] Therefore, the emergence of a negative pressure suction air source terminal with a sealed structure design is very necessary. Contents of the invention [0004] In order to solve the above technical problems, the present invention provides a negative pressure sucti...
