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.
