Temperature compensator for anesthetic vaporizer, anesthetic vaporizer, and anesthesia machine

摘要

The present invention provides a temperature compensator for an anesthetic vaporizer, an anesthetic vaporizer and an anesthesia machine. The temperature compensator comprises a compensator base for mounting various components of the temperature compensator thereon, a compensator cover for constituting a bypass control valve with the compensator base, and a bimetallic plate for bending in response to temperature changes and thereby changing the opening and closing degree of the bypass control valve. With the present invention, the flow-pressure characteristics can be accurately controlled by adjusting the pressure drop of the temperature compensator under two different flow conditions. Because of the controllable flow-pressure characteristics of the temperature compensator, the output concentrations obtained under different flow conditions can all meet the requirements.
