Abstract

880,824. Respiratory appliances. OXYGENAIRE (LONDON) Ltd. Aug. 16, 1960 [Dec. 10, 1959], No. 42059/59. Class 81 (2). Oxygen administering apparatus comprises a flexible face mask 11 having a number of apertures 17 for the escape of exhaled air and an inlet fitting 12 having a nozzle 20 through which oxygen issues at relatively high velocity, so as to entrain air through lateral apertures 22 as it enters the mask. The proportion of oxygen remains approximately constant irrespective of the total rate of flow. A second inlet tube 19, having a relatively large outlet, may also supply oxygen but as this does not produce an injector effect it serves merely to control the proportion of oxygen supplied to the patient. A conical extension 13 on the fitting 12, within the mask, serves to spread it for convenient use and an elastic loop 16 holds the mask in position. The two supplies of gas are preferably taken from a single supply canister through separate control valves, each having its own flow-meter.
