An Anesthetic Evaporator Adaptive to Variations in Evaporation Temperature

Abstract

The invention relates to the field of internal medicine anesthesia equipment, in particular to an anesthetic agent evaporator adaptive to changes in evaporating temperature. It includes a plurality of evaporation chambers for accommodating liquid anesthetics and evaporating liquid anesthetics to form anesthetic vapors, a gas collection chamber for collecting anesthesia vapors discharged from multiple evaporation chambers, and a control mechanism; one end of the evaporation chambers is connected with a supply of carrier gas The carrier gas pipe that enters, and the other end of the evaporation chamber are equipped with an exhaust pipe for the carrier gas to carry anesthetic vapor and be discharged from the evaporation chamber. All exhaust pipes are connected to the gas collection chamber through the control mechanism, and can be evaporated The cooled evaporating chamber is disconnected from the plenum chamber, and communicated with the plenum chamber again after the evaporating chamber absorbs ambient heat and heats up. The invention can overcome the technical problem that after the liquid anesthetic is evaporated and cooled, the evaporation rate continues to decrease, 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.

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...
