Claims
- 1. 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, one end of which is pivotably mounted to an exterior side of the headband near one end thereof, to rotate 360° with respect to the headband about an axis passing through the headband and a portion of the sleeve where it is mounted; (c) an elongated tubular boom secured within the sleeve to extend from the other end of the sleeve so that the free end of the boom is located when in operation at a space in front of, and proximal to, the patient's nose and mouth; (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 end of the boom within the sleeve, and the sleeve, constructed so as when in operation, to hold securely an oxygen delivery tube from an oxygen source in fluid communication with that end of the boom so as to deliver oxygen from the source to the boom for discharge through the diffuser.
- 2. A system according to claim 1, wherein the tubular boom is secured within the sleeve for telescopic, longitudinal adjustment of the boom with respect to the sleeve to facilitate positioning of the oxygen diffuser with respect to the patient's nose and mouth.
- 3. A system according to claim 1, wherein interior walls of the sleeve are formed so as to frictionally engage a portion of the oxygen delivery tube when in operation.
- 4. A system according to claim 1, wherein the ends of the headband are widened so as to spread the engaging force of the headband on a patient's head.
- 5. A system according to claim 4, wherein interior surfaces of the widened ends of the headband are provided with inwardly extending ribs to assist in frictionally engaging a patient's head when the headband is in position.
- 6. A headband according to claim 4, wherein the headband is constructed so as to be of a size and shape to enable it to be fit both over or behind a patient's head when its ends are in position on the sides of a patient's head.
- 7. A headband according to claim 4, wherein intermediate portions of the headband are provided with apertures through which a patient's hair may extend, to further facilitate holding the headband in position on a patient's head and prevent it from becoming dislodged from that position.
- 8. A system according to claim 3, wherein stop means are provided within the sleeve to limit the telescopic longitudinal adjustment of the boom with respect to the sleeve between two longitudinal extremities.
- 9. A system according to claim 1, wherein the boom is constructed so as to be bendable to a particular shape to facilitate its positioning with respect to a patient's nose and mouth.
- 10. A system according to claim 9, wherein a wire is embedded in the tubular boom to permit bending of the boom to a particular shape and maintaining of that shape.
- 11. A system according to claim 1, wherein the diffuser comprises a body having sides circumscribing a base, the walls defining an interior surface of generally concave configuration, to direct the 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 boom.
- 12. A system according to claim 11, wherein the interior surface is of somewhat triangular, cup shape to follow the shape of the nose/mouth nexus of a patient when in position on a patient.
- 13. A system according to claim 2, wherein a wire is embedded in the tubular boom to permit bending of the boom to a particular shape and maintaining of that shape.
- 14. A system according to claim 2, wherein the diffuser comprises a body having an interior surface of generally concave configuration, to direct the flow of oxygen generally towards the patient's mouth and nose through the diffuser port.
- 15. A system according to claim 4, wherein the interior surface is of somewhat triangular, cup shape to follow the shape of the nose/mouth nexus of a patient when in position on a patient.
- 16. A system according to claim 11, wherein the diffuser further comprises a baffle seated over the outlet so as to assist in mixing of oxygen with ambient air and avoid a direct flow of oxygen towards the patient's face.
- 17. 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, one end of which is pivotably mounted to an exterior side of the headband near one end thereof, to rotate 360° with respect to the headband about an axis passing through the headband and a portion of the sleeve where it is mounted; (c) an elongated tubular boom secured within the sleeve to extend from the other end of the sleeve so that the free end of the boom is located when in operation at a space in front of, and proximal to, the patient's nose and mouth; (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 end of the boom within the sleeve, and the sleeve, constructed so as when in operation, to hold securely an oxygen delivery tube from an oxygen source in fluid communication with that end of the boom so as to deliver oxygen from the source to the boom for discharge through the diffuser, the tubular boom being secured within the sleeve for telescopic, longitudinal adjustment of the boom with respect to the sleeve to facilitate positioning of the oxygen diffuser with respect to the patient's nose and mouth.
- 18. A system according to claim 17, wherein the boom is constructed so as to be bendable to a particular shape to facilitate its positioning with respect to a patient's nose and mouth.
- 19. A system according to claim 18, wherein the diffuser comprises a body having sides circumscribing a base, the walls defining an interior surface of generally concave configuration, to direct the 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 boom.
