Suction valve cover and suction assembly containing the same

Abstract

The invention discloses an inhalation valve cover which comprises a valve cover body. The valve cover body is provided with space for containing an inhalation valve and a connecting hole used for being connected with an oxygen sensor, and the connecting hole is a through hole communicated with the inside and the outside of the valve cover body. By arranging the connecting hole on the inhalation valve cover body and communicating the oxygen sensor with the inside of the inhalation valve through the connecting hole, the oxygen sensor is enabled to be capable of timely detecting oxygen concentration inside the inhalation valve cover, so that stability in oxygen concentration detection in the process of surgery is guaranteed, and safety accidents are avoided. The invention further discloses an inhalation component. The inhalation component is mainly characterized in that the connecting hole is arranged on the inhalation valve cover, the inhalation cover is connected on a mounting seat in a pressed manner through a locking nut, and a sealing ring is arranged at a position where the inhalation valve cover is connected with the connecting seat, so that oxygen concentration detection can be enabled to be more accurate, sealing performance is high, and great convenience in demounting is realized.

Description

technical field [0001] The invention relates to the technical field of anesthesia machines, in particular to an inhalation valve cover and an inhalation assembly containing the same. Background technique [0002] An anesthesia machine is a medical machine used for general anesthesia, oxygen supply, and assisted or controlled breathing. It requires that the concentration of oxygen provided and inhaled anesthetic should be accurate, stable and easy to control. Anesthesia machines can be divided into three types according to the number of functions and the complexity of the structure: ① Almighty type: complex structure, complete functions, with electronic or computer-controlled respiratory management system, monitoring instrument, alarm system, and some automatic recording systems; ② Universal type : The structure and function are simpler than the previous item, but still have basic and important structures and components, such as safety systems such as nitrous oxide automatic ...

AI Technical Summary

Problems solved by technology

The structure of the suction valve cover can make the internal valve movement visible through the glass baffle 104, and the hollow valve cover body 100 provides the necessary space for the movement of the valve valve, and the valve cover body 100 is set at the same time The connection thread 102 makes the installation and disassembly of the suction valve cover more convenient, but this suction valve cover has the following defects: 1. The structure of the suction valve cover makes the oxygen concentration sensor only be installed in the suction valve. Outside the air port, this cannot guarantee the stability of the oxygen concentration detection during the operation, which makes the anesthesia machine a potential safety hazard; The sealing of the connection method is not strong, and the threaded connection is prone to problems such as slippage after long-term use, resulting in loose connection, air leakage, and environmental pollution; 3. The structure of the suction valve cover is complicated, and the corresponding The production process is also very complicated, resulting in high production costs and a high product scrap rate; 4. By adopting a split design for the glass baffle and the valve cover body, the gap between the valve cover body and the glass baffle is also easy. Make the suction valve cover leak, waste energy and pollute the environment
