Volatile anesthetics showed a liquid at room temperature. Evaporator can effectively evaporation of volatile liquid anesthetic gases, and to accurately adjust the output of the concentration of anesthetic vapors. Anesthetics need the heat of evaporation, the evaporator temperature is around the rate of evaporation of volatile anesthetics, the main factors. Modern anesthesia machines are widely used type of temperature compensation a flow evaporator, that is, the fresh gas flow in the temperature or change, through the automatic compensation mechanism to maintain a constant evaporation rate of volatile anesthetics, inhaled anesthetics to ensure the evaporator to leave output concentrations. Since the boiling point of different volatile anesthetics and saturation vapor pressure and other physical characteristics, so that, exclusive of the evaporator with drugs, such as the evaporator enflurane, isoflurane, evaporator, another can not be universal. Modern anesthesia machines multi-evaporator loop placed in the anesthesia breathing, the oxygen in air with a separate connection, evaporation of volatile anesthetics out of steam mixed with the main flow for the patient after inhalation. evaporator & vaporizer Mainly by the heating chamber and evaporation chamber composed of two parts. Evaporation to the liquid heating chamber to provide the heat needed to promote the vaporization of the liquid boiling; evaporation chamber so that complete separation of gas-liquid two-phase. Steam heated room with a large number of liquid foam, to a larger space, evaporator, these liquids pool by themselves or demister to the role of such separation and steam. Usually demister in the top of evaporation chamber.
