Claim:
Device for recovering anaesthetics in anaesthetic treatment of a patient, which device comprises; a housing having a first opening and a second opening for formation of a flow path to and from the patient in the housing for a breathing medium, an absorption body arranged in the housing and having a capacity of absorbing and desorbing anaesthetics, a valve means comprising a rotatable unit that is adjustable between an active position, in which a flow path to and from the patient passes through the absorption body, and a passive position, in which a flow path to and from the patient passes through the housing without passing through the absorption body, wherein the absorption body retains unchanged location in the housing in both valve positions, wherein one of said openings is arranged at the rotatable unit, said opening being in a first rotational position on a side of the absorption body and in a second rotational position on an opposite side of the absorption body, wherein the housing is in the form of a box having a height that is smaller than a smallest extension thereof transverse to the height, wherein the absorption body is plate-shaped and is in the active position thereof substantially perpendicular to the height, and wherein the housing is configured such that, in both the active and passive positions, air flows from each opening in a flow direction that is substantially parallel to a plane defined by a plate-shaped surface of the absorption body.
