特徴とする、気化性液体麻酔剤気化器。[Scope of Claim for Utility Model Registration] In an anesthesia machine, a carrier oxygen gas mass flow controller is installed branching from the supply oxygen piping, and a carrier oxygen gas mass flow controller is installed using a microcomputer based on the input values of the total flow rate and vaporizable liquid anesthetic agent concentration%. Oxygen flow rate = total flow rate x vaporizable liquid anesthetic concentration % is calculated, and a command signal is sent to the mass flow controller to control the carrier oxygen gas flow rate. Place a temperature sensor at the inlet and outlet of the vaporizer, and a heater between the inlet temperature sensor and the vaporizer, or within the vaporizer, so that the temperature of the carrier oxygen gas at the inlet and outlet of the vaporizer becomes equal. A vaporizable liquid anesthetic vaporizer characterized by:
