A DEVICE FOR RECOVERING ANAESTHETIC

摘要

A device for recovering anaesthetic during the use of inhaled anaesthetics is connected to a patient and comprises an anaesthetic evaporator for supplying anaesthetic to the patient and an absorption filter for absorption and desorption of the medium. The device comprises a body (4) applied between the absorption filter (6; 16) and the patient (P), the gases breathed by the patient passing accross said body and the anaesthetic evaporating on the surface thereof. The absorption filter is in the form of a flat element (6) applied in the flow path of the gas breathed by the patient and contains or consists of fibres of active carbon. Furthermore, the absorption filter is movably applied in a housing (5; 15) between a position in which substantially all the gases breathed pass through the filter and a position in which a small portion of the gases breathed passes through this.
