ABSTRACT:
An improved oxygen mask, particularly useful for treating patients requiring inhalation therapy, wherein the extent of oxygen dilution with room air may be selectively controlled to provide different predetermined oxygen concentrations. The diluter is interposed in the line between the inlet hose of the mask and the oxygen supply tube and essentially comprises two closely-fitting parts: a tapered tubular body which houses an integral ejector nozzle, and a tapered tubular sleeve which is fitted upon the body for rotational movement into any of a plurality of selected positions but is securely locked against axial movement upon that body. The parts have apertures which are moved into or out of alignment as the sleeve is rotated into different angular positions of adjustment. An aerosol adapter may be removably mounted upon a projecting end portion of the body for directing vapors towards the inlet apertures of the diluter.
