Anesthetic gas recovery device for anesthesia machine

Abstract

The present invention relates to the technical field of anesthesia equipment, in particular to an anesthetic gas recovery device for an anesthesia machine, comprising a fixed plate, the periphery of the fixed plate is spirally connected with a first fixed horizontal rib, and the central position of the top of the fixed plate is fixedly connected with a A vertically arranged pipeline, the periphery of the bottom end of the pipeline is sequentially sleeved with a shock-absorbing rubber plate and a shock-absorbing sponge, and the shock-absorbing rubber plate is provided with a through hole, and a shock-absorbing spring is placed inside the through hole , the bottom end of the first fixed horizontal bar is fixedly connected with an air pipe, and the central position of the bottom end of the first fixed horizontal bar is fixedly connected with a vertically arranged nozzle, and the bottom end of the air pipe is fixedly connected with a second fixed horizontal bar. In the present invention , by setting the rubber ring on the periphery of the fume hood, the device can be made to fit people's faces more closely and comfortably, which increases the comfort of the product, has huge economic benefits and broad market prospects, and is worthy of promotion and use.

Description

technical field [0001] The invention relates to the technical field of anesthesia equipment, in particular to an anesthesia gas recovery device for an anesthesia machine. Background technique [0002] The anesthesia machine sends the anesthetic into the alveoli of the patient through a mechanical circuit, forming a partial pressure of the anesthetic gas, which diffuses into the blood, and directly inhibits the central nervous system, thereby producing the effect of general anesthesia. The anesthesia machine is a semi-open anesthesia device. It is mainly composed of anesthesia evaporation tank, flow meter, folding bellows ventilator, breathing circuit, corrugated pipeline and other components. Therefore, the demand for anesthesia gas recovery device for anesthesia machine is increasing day by day. [0003] At present, most spray anesthesia machines are very prone to leakage during use. On the one hand, it causes great damage to the environment, and on the other hand, it diff...

AI Technical Summary

Problems solved by technology

[0003] At present, most spray anesthesia machines are very prone to leakage during use. On the one hand, it causes great damage to the environment, and on the other hand, it diffuses too much anesthetic gas into the environment, causing great waste. At the same time Most spray anesthesia machines do not recover gas thoroughly, and at the same time, the anesthetic gas is corrosive gas, and it is easy to corrode the pipeline of the spray anesthesia machine for a long time, resulting in the frequent replacement of the pipeline of the spray anesthesia machine, which increases the reduce the use cost, therefore, a kind of anesthesia gas recovery device for anesthesia machine is proposed to solve the above problems
