Oxygen diffuser support
First Claim
1. A lightweight oxygen delivery device for a patient comprising:
- (a) an elongated tube, the tube being bendable to a particular shape and capable of maintaining that shape, the tube to carry oxygen and having a first end and a second end, the first end to be releasably connectable to an oxygen delivery source;
(b) a rigid elbow having a pair of ends and an oxygen delivery passageway extending between those ends, one of those ends being secured to the second end of the tube;
(c) an oxygen diffuser connected to the other end of the elbow, the diffuser comprising a body having a wall, the interior surface of which wall is of generally concave configuration, circumscribing a centrally positioned oxygen outlet communicating with said other end of the elbow so as to receive oxygen from the elbow and direct the flow of oxygen delivered from the elbow generally towards the patient=s nose and mouth;
(d) a baffle seated within the diffuser over the oxygen outlet, the baffle shaped and positioned so as to change oxygen flow from the diffuser from jet flow to turbulent flow;
(e) a support for the diffuser, the support comprising a securing means for the elongated tube, the securing means being located at the vertex of front portions of rigid arms forming a v-shaped front of the support, a resilient front strap extending between rear portions of the arms and a resilient back strap extending between ends of the rear portions of the arm, in operation, the back strap arranged so as to extend behind a user'"'"'s head and be releasably adjustable to an operative length to seat the support securely on a user'"'"'s head with a portion of the front of the user'"'"'s face bearing against the front strap, so that, when so seated, the diffuser is held in a position spaced from proximal to the patient'"'"'s nose and mouth.

Abstract
A support for an oxygen diffuser for delivering a plume of oxygen-enriched air to a space in front of a patient'"'"'s nose and mouth. The support comprises a means for holding a tube associated with the oxygen diffuser. This means is located at the vertex of front portions of rigid arms forming a v-shaped front of the support. A resilient front strap extends between rear portions of the arms. A resilient back strap extends between ends of the rear portions of the arms. In operation, the back strap is arranged so as to extend behind a user'"'"'s head and is releasably adjustable to an operative length to seat the support securely on a user'"'"'s head with a portion of the front of the user'"'"'s face bearing against the front strap, so that, when so seated, the diffuser is held in a position spaced from but proximal to the patient'"'"'s nose and mouth.
