Anesthetic evaporator self-adaptive to evaporation temperature change

Abstract

The invention relates to the field of internal medicine anesthesia equipment, in particular to an anesthetic evaporator self-adaptive to evaporation temperature change. The anesthetic evaporator comprises multiple evaporation chambers, a gas collection chamber and a control mechanism, and the evaporation chambers are used for containing a liquid anesthetic and evaporating the same to form anesthetic vapor, the gas collection chamber is used for collecting the anesthetic vapor discharged by the evaporation chambers; one end of each evaporation chamber is connected with a carrier gas pipe for carrier gas to enter while the other end of the same is provided with a gas discharging pipe for discharging the carrier gas carrying the anesthetic vapor from the evaporation chamber, and all gas discharging pipes are connected with the gas collection chamber through the control mechanism, can disconnect communication of the evaporation chambers cooled through evaporation with the gas collection chamber through the control mechanism and can be connected with the gas collection chamber after the evaporation chambers rise in temperature when absorbing environment heat. By the anesthetic evaporator, the technical problem that anesthetic vapor output by existing evaporators is unstable in concentration caused by the fact that the concentration of the anesthetic vapor is reduced as evaporation speed is continuously lowered after the liquid anesthetic is evaporated and cooled can be overcome.

Description

technical field [0001] The invention relates to the field of internal medicine anesthesia equipment, in particular to an anesthetic agent evaporator adaptive to changes in evaporating temperature. Background technique [0002] Inhalation anesthesia is the anesthesia effect formed by the volatilized vapor of the anesthetic agent entering the human body from the respiratory tract. The drugs include ether, isoflurane, and nitrous oxide. The anesthetic enters the blood through the alveolar arteries, passes through the blood-brain barrier with blood circulation, and finally reaches the brain. After entering the central nervous system, it can block the function of neurotransmission and cause anesthesia. After anesthesia, inhaled anesthetics are rarely metabolized by the liver or excreted by the kidneys, and are mainly excreted through the respiratory tract in their original form. Therefore, inhaled anesthetics have the advantages of being easier to discharge, quick recovery from...

Problems solved by technology

[0005] The purpose of the present invention is to provide an anesthetic evaporator that adapts to changes in the evaporation temperature, so as to overcome the problem that the evaporation speed continues to decrease after the liquid anesthetic is evaporated and cooled, so that the concentration of the anesthetic vapor output by the evaporator decreases, resulting in an unstable concentration of the anesthetic vapor output by the evaporator. technical problem
