Abstract

533,297. Artificial respiration apparatus. DAVIS, Sir, R. H. Aug. 8, 1939, No. 22920. [Class 81 (ii)]] Artificial respiration apparatus comprises an oxygen supply 2, a mouthpiece 4 to be used by a rescuer, a mask 1 to be applied over the patient's mouth and nose, conduit means connecting the mouthpiece to the oxygen supply on the one hand and to the mask on the other, and non-return valve 16, 20 which automatically cut off communication between the mask and mouthpiece during inhalation of oxygen through the latter by the rescuer, and cut off communication between mouthpiece and oxygen supply when the rescuer is exhaling and forcing an atmosphere rich in oxygen with the addition of some carbon dioxide into the lungs of the patient. The oxygen supply comprises a cylinder of compressed oxygen connected to the rest of the apparatus through a pressure reducing valve 12. A small reservoir in the form of an india-rubber bag 15 is provided to accommodate oxygen delivered from the cylinder during the intervals between successive inhalation phases of the rescuer. The mouthpiece 4 is preferably provided with a filter 5.
