A device in artificial respiration- and/or anaesthetic systems comprising: a first conduit (2) extending from an inhalation member (1) connectible to the patient, said first conduit being arranged for the supply of gas from a gas source; a second conduit (4) for removal of exhalated gas; a flexible container (3) arranged in said first container (1) at some distance from the inhalation member (1); and a stop valve (6) arranged in said second conduit (4) at some distance from the inhalation member (1), said valve (6) being arranged to close by means of a membrane (27) or the like by the action of pressurized gas from the system. The stop valve (6) comprises a second manually adjustable control valve (16), which in a first end position is arranged to provide a flow communication (24, 25, 26) between the pressure face of the membrane (27) and the pressurized gas, and in a second position is arranged to shut off the supply of gas and open a communication passage (28, 29) between the pressure face of the membrane and the atmosphere. |
