Abstract
The invention relates to a device and method for recovering anaesthetic during the use of inhaled anaesthetics. An anaesthetic reflector (,) is used which absorbs anaesthetic medium from the gas exhaled by the patient and desorbs anaesthetic medium to the gas inhaled by the patient. According to the invention a moisture-heat exchanger (,) is arranged in the system which, in an equivalent manner, recovers water vapor from the gas exhaled to the gas inhaled. The moisture-heat exchanger (,) is preferably located between the anaesthetic reflector (,) and the patient (,). The device and the method according to the invention enable the gas inhaled to be moistened to prevent dehydration, as well as increasing the efficiency of the reflector (,).
