ANAESTHETIC EVAPORATOR FOR DOSING DIFFERENT ANAESTHETICS

摘要

In an anaesthetic evaporator with a dosing unit 2 and with a plurality of evaporator chambers 3 which can be selectively attached to the dosing unit for different anaesthetics 8, the dosing unit (2) is provided with a heating and cooling means 4 engaging into the evaporator chamber 3 operable under control of a regulator 5 to set a constant vapour pressure of 700 millibar for each anaesthetic. Cooling means 11 specific to the respective chamber and its anaesthetic signals the regulator which also receives a sensed temperature of the anaesthetic and actuates the heating and cooling means to achieve the set vapour pressure. In another embodiment, the respective anaesthetic is provided in a supply container which is attachable to an evaporator chamber firmly connected to the dosing unit and mounting a Peltier heating and cooling device.
