Abstract: A device for recovering anaesthetic. During the administration of inhaled anaesthetic, the device is connected to a patient. It includes an anaesthetic evaporator for supplying anaesthetic to the patient and an absorption filter for absorption and desorption of the medium. The device includes a body placed between the absorption filter and the patient with the gases breathed by the patient passing across the body and the anaesthetic evaporating on the surface thereof. The absorption filter is in the form of a flat element placed in the flow path of a gas breathed by the patient and contains fibers of active carbon. The absorption filter is movably arranged in a housing between a position in which substantially all the gases breathed pass through the filter and the position in which a small portion of the gases breathed passes therethrough.

Abstract: The invention relates to a device and method for recovering anaesthetic during the use of inhaled anaesthetics. An anaesthetic reflector (5) 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 (12) 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 (12) is preferably located between the anaesthetic reflector (5) and the patient (1). 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 (5).
