Abstract

An anesthetic evaporator according to the bypass principle, in which a carrier gas system is partially led through an evaporation chamber, is enriched with an anesthetic vapor to saturation there, and is again fed into the bypass flow. The function of the elements that influence the metering are not impaired by the penetration of anesthetic in an unintentional position other than the position intended for operation, and that the anesthetic located in the mixed gas outlet is not influenced by anesthetic located outside the evaporation chamber. Either the evaporation chamber line leading to the evaporation chamber or the return line leading from the evaporation chamber to the flow regulating valve opens into an intermediate container, from which a channel communicates with the interior of the evaporation chamber. Anesthetic once penetrated into the intermediate container cannot accumulate even when the anesthetic evaporator is repeatedly placed into an unintended position, but an amount which does not impair the function of the anesthetic evaporator will remain in it [the intermediate container], or it evaporates during the operation, or it can again be emptied into the evaporation chamber in a simple manner.
