Metering device for anesthetics

摘要

A device for metering anesthetic is provided such that a new anesthetic is immediately available for the metering when the anesthetic is changed. The metering device has an assembly unit that can be removed from the medical apparatus as a module with a reservoir ( 4 ) for a liquid anesthetic, an intermediate container ( 9 ) arranged downstream of the reservoir ( 4 ), a metering gas source ( 11 ) connected to the intermediate container ( 9 ) and a metering element ( 14 ) for anesthetic on the discharge side of the intermediate container ( 9 ). An evaporator chamber ( 15 ) may be provided for evaporating the metered anesthetic. A connecting device lets through at least anesthetic vapor as an interface between the assembly unit ( 1 ) and the medical apparatus ( 2 ).
