Circulating closed anesthesia machine for anesthesiology department

Abstract

The invention relates to the technical field of anesthesia equipment, and discloses a circulating closed anesthesia machine for the anesthesiology department, which comprises an outer cylinder, a heating seat is fixedly mounted at the bottom of the outer cylinder, an air inlet is formed in the top of the left side of the outer cylinder, an air guide channel is formed in the top of the outer cylinder, and an air outlet is formed in the right side of the top of the outer cylinder. The air inlet is communicated with the air outlet through an air guide channel, an evaporation chamber is movably installed in the outer cylinder and located above the evaporation chamber, the back of the evaporation chamber is fixedly communicated with a liquid adding pipe, and the top of the evaporation chamber is movably sleeved with an inner cylinder. Through the arrangement of the electromagnetic device I and the downward pressing plug, the pressure of the downward pressing plug on anesthesia steam is adjusted by utilizing the attraction force of the electromagnetic device I on the magnet in the downward pressing plug, so that the concentration of the anesthesia steam is adjusted, the anesthesia steam is mixed with carrier gas after reaching a certain concentration, and the concentration of the anesthesia steam in the carrier gas is guaranteed; therefore, accurate control over the anesthesia process can be enhanced.

Description

technical field [0001] The invention relates to the technical field of anesthesia equipment, in particular to a closed loop anesthesia machine used in anesthesiology department. Background technique [0002] The closed cycle anesthesia machine uses low-flow anesthesia mixed gas to supply the patient with one-way flow through the escape valve (door), and the exhaled gas enters the CO through the expiratory valve. 2 The absorber is reused, and its structure is mainly composed of oxygen supply and nitrous oxide device, gas flow meter, evaporator, CO 2 Absorber, one-way valve, breathing tube, outgassing valve, air storage bag, etc. Among them, the basic principle of the volatilization tank is to use the changes in the temperature and heat source of the surrounding environment to convert the anesthetic drug into vaporized gas, through a certain A certain amount of carrier gas, a part of which carries away the saturated anesthetic gas, becomes a certain concentration of anestheti...

AI Technical Summary

Problems solved by technology

[0003] First of all, after the carrier gas enters the vaporizer, it is divided into two parts, one part of the carrier gas is mixed with the anesthetic vapor and taken out, but the distribution of the two parts of the carrier gas is not precisely controlled. Part of the carrier gas proportion of the anesthetic gas is too large, and the air flow is too strong, and the amount of anesthetic vapor carried at the same time is too large, causing risks in the subsequent use process. , the temperature decreases, the output of anesthetic vapor decreases, resulting in insufficient concentration, resulting in a decrease in the subsequent anesthetic effect
