Method and device for supplying oxygen to a patient

A system for delivering oxygen to a target, comprising:

• a pump configured to deliver oxygen to the target;
• first and second elongate hollow members operatively coupled to the pump, the elongate hollow members configured to be positioned about the target such that a distal end of the elongate hollow members are in opposing directions and are disposed at least 150 mm in a clear path from the target, and wherein a substantially straight portion of tubing of each elongate hollow member having a low coefficient of friction is longitudinally directed toward the target, said substantially straight portion being at least 300 mm in length;
• a first attachment device coupled to the first elongate hollow member and configured to position the first elongate hollow member, wherein the first attachment device is not in contact with the target;
• a second attachment device coupled to the second elongate hollow member and configured to position the second elongate hollow member, wherein the second attachment device is not in contact with the target;
• and
• a flow of oxygen delivered by the pump, emanating as a first stream of oxygen from the distal end of the first elongate hollow member and a second stream of oxygen from the distal end of the second elongate hollow member in a substantially collimated laminar state and extending from the elongate hollow members until the first and second streams of oxygen contact the target at which point the first and second streams of oxygen transform into a turbulent state.

A method of delivering oxygen, comprising:

• positioning a first elongate hollow member with a substantially straight portion of tubing longitudinally directed toward a target, wherein the substantially straight portion is at least 300 mm in length, and wherein a distal end of the elongate hollow member is positioned at least 150 mm in a clear path from the target;
• transmitting a stream of oxygen through the first elongate hollow member at between approximately 2 and 10 liters per minute;
• positioning the first elongate hollow member and a second elongate hollow member normal to the target, wherein the flow rate of oxygen through each of the two elongate hollow members is substantially equal and the direction of flow from the first and second elongate hollow members intersect with one another;
• wherein the stream of oxygen exits the distal end of the elongate hollow member in a substantially collimated laminar state.
