Abstract:
A lightweight oxygen delivery system for a patient comprising:(a) a curved resilient headband to extend between ends from side to side over a patient's head and to be comfortably seatably engaged thereon; (b) an elongated rigid sleeve, a first end of which is pivotably mounted to an outward-facing surface of the headband near one end thereof, to rotate with respect to the headband and thereby permit use of the system on either side of the patient's head; (c) an elongated tubular boom secured within a second end of the sleeve to extend from that end of the sleeve when in operation to terminate at a free end located at a space in front of, and proximal to, a nose and mouth of the patient; (d) an oxygen diffuser at said free end of the boom, through which diffuser oxygen may be delivered from the boom to the space in the vicinity of the patient's nose and mouth; the diffuser comprising a body having sides circumscribing a base, the sides forming walls defining an interior surface of generally concave configuration, wherein the interior surface is of somewhat triangular, cup shape to follow a shape of a nose/mouth nexus of the patient when in position on the patient, when in operation to direct flow of oxygen generally towards the patient's mouth and nose through the diffuser from an outlet positioned in the base and communicating with the tubular boom; the sleeve, constructed so as to hold securely an oxygen delivery tube from an oxygen source in fluid communication with the corresponding end of the tubular boom so as to deliver oxygen from the oxygen source to the tubular boom for discharge through the diffuser.
