Abstract
An anesthetic dispensing device (), to which a carrier gas stream is fed for enriching with anesthetic, has the gas stream split into two partial gas streams, one of which flows through a bypass channel () unchanged and the other of which is fed to an evaporation chamber (), where the partial gas stream is saturated with anesthetic. In a mixing point (), both partial gas streams are mixed to form an anesthetic gas stream, which leaves the anesthetic dispensing device through the anesthetic gas outlet (). A control unit () is provided that is configured to generate a control signal for an electric motor drive () for adjusting the valve opening of the valve element () on the basis of a concentration of the anesthetic in the anesthetic gas needed at the anesthetic gas outlet () and at least one temperature-specific correction factor.
