Abstract

A nasal assembly for delivering breathable gas to a patient includes a frame having an integrally formed first connector portion. A nozzle assembly includes a gusset or base portion and a pair of nozzles. At least one inlet conduit is structured to deliver breathable gas into the frame and nozzle assembly for breathing by the patient. A pair of second connector portions are removably and rotatably connected to respective first connector portions of the frame and are in communication with respective inlet conduits, e.g., directly or via angle connectors. A headgear assembly is removably connected to the pair of second connector portions and/or the angle connectors so as to maintain the frame and the nozzle assembly in a desired adjusted position on the patient'"'"'s face.

Claims

1. A nasal assembly for delivering breathable gas to a patient, comprising:

a frame having a main body and a side frame member provided on each lateral side of the main body;

a nozzle assembly including a pair of nozzles, the nozzle assembly being coupled with the main body of the frame with the pair of nozzles structured to sealingly engage with nasal passages of a patient'"'"'s nose in use;

an inlet conduit structured to deliver breathable gas into the frame and nozzle assembly for breathing by the patient;

a headgear assembly to maintain the frame and the nozzle assembly in a desired adjusted position on the patient'"'"'s face; and

a plug including a vent portion structured to allow passage of exhaled gas, the vent portion including a sintered material,

wherein the plug is provided to one said lateral side of the frame and the inlet conduit is provided to the other said lateral side of the frame.

2. The nasal assembly according to claim 1, wherein the frame and nozzle assembly are rotatable with respect to the headgear so as to adjust a position of the nozzles with respect to the patient'"'"'s nose in use.

3. The nasal assembly according to claim 2, wherein the headgear assembly allows symmetrical adjustment.

4. The nasal assembly according to claim 1, wherein the sintered material is hydrophobic.

5. The nasal assembly according to claim 1, wherein the vent portion is separate and distinct from the inlet conduit and the delivery of breathable gas into the frame and nozzle assembly.

6. The nasal assembly according to claim 1, wherein positions of the plug and the inlet conduit are structured to be selectively interchanged.

7. The nasal assembly according to claim 1, wherein the inlet conduit includes an elbow that is angled from the frame and nozzle assembly.

8. The nasal assembly according to claim 1, wherein the nozzle assembly includes a plurality of visual indicators which can be selectively matched with a reference indicator provided adjacent the visual indicators.

9. The nasal assembly according to claim 8, wherein the reference indicator is provided on a yoke of the headgear assembly.

10. The nasal assembly according to claim 1, wherein the headgear assembly includes yokes structured to provide stability to sides of the headgear assembly.

11. The nasal assembly according to claim 10, wherein yoke includes a yoke ring provided to the side frame member of the frame.

12. The nasal assembly according to claim 1, further comprising a seal ring provided to each side frame member, the seal ring structured to provide a seal and/or locking interface with the respective plug and inlet conduit.

13. The nasal assembly according to claim 12, wherein the vent portion is sized to fit within the seal ring.

14. The nasal assembly according to claim 1, wherein the vent portion is sized to fit within the side frame member.

15. The nasal assembly according to claim 1, further comprising a baffle provided to an inside portion of the frame, the baffle structured to at least partially separate a vent exit from an air inlet.

16. The nasal assembly according to claim 15, wherein the baffle includes a base plate connected to the inside portion of the frame and at least one arm projecting away from the base plate.

17. The nasal assembly according to claim 1, wherein the plug and the inlet conduit are structured to be removably connected to the respective side frame member.
