ABSTRACT:
A system for supplying supplemental oxygen to a patient includes a nosepiece and an oxygen tube holder. The nosepiece has a conical section with a truncated tip and a flexible annular skirt and is formed with a primary axial oxygen passageway and a pair of lateral secondary oxygen passages which lead from the primary passageway to outlets on the conical surface. Optionally, an additional pair of passageways lead through the nosepiece from a position outwardly of the skirt into the axial passageway. In alternative forms, the nosepiece has a tear-away skirt portion to permit the diameter to be changed to accommodate the individual, and has external air passageways formed as recesses on the conical surface. The tube holder is arcuate and is adapted to be mounted on an EKG electrode-type patch on a cheek prominence and supports an oxygen delivery tube to the nosepiece. The electrode post is received within a curved slot formed in the holder base. Grippers on the base hold the oxygen tube in a relation conforming to the curvature of the base.
