    • 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.
    • 根据旁路原理的麻醉蒸发器,其中载气系统部分地通过蒸发室,其富含麻醉蒸气以在那里饱和,并再次进入旁路流。 影响计量的元件的功能不会因麻醉剂渗透到除了用于操作的位置之外的非故意位置而受到影响,并且位于混合气体出口中的麻醉剂不受位于蒸发室外部的麻醉剂的影响。 通向蒸发室或从蒸发室通向流量调节阀的蒸发室管线通向中间容器,通道与蒸发室的内部连通。 即使当麻醉蒸发器重复放置在非预期位置时,一旦渗透到中间容器中的麻醉剂也不能积聚,但是不损害麻醉蒸发器功能的量将保留在其中[中间容器],或者在 或者可以以简单的方式再次排入蒸发室。
