Abstract

mask apparatus for a respiratory treatment can permit delivery of breathable gas to a user. In one example, the mask may employ a frame and cushion to form a seal for both mouth and nose. The frame may be adapted for coupling with a respiratory treatment apparatus so as to permit communication of a pressurized gas from the respiratory treatment apparatus. The cushion, which may be foam, may have a substantially under the nose configuration or over the nose configuration. The mask may have a common plenum chamber for both nose and mouth. The cushion may further define a centrally open lip superior region. The cushion may be adapted to couple with the frame directly or to the frame in conjunction with a cushion support clip. Various features of the cushion may further promote sealing and comfort for the under the nose design.

Claims (35)

CLAIMS :
1. A mask apparatus for a respiratory treatment comprising: a frame adapted to couple with a respiratory treatment apparatus so as to permit communication of a pressurized gas to a respiratory system of a patient from the respiratory treatment apparatus; and a cushion adapted to couple with the frame, the cushion configured as a substantially under nose seal portion and a mouth seal portion, the under nose seal portion comprising a sub-nasal ridge formed as a semi- peripheral sealing boundary about both nares of the patient.
2. The mask apparatus of claim 1 wherein the cushion comprises a triangular ring having a common nasal and mouth aperture.
3. The mask apparatus of either claim 1 or claim 2 wherein the cushion is foam.
4. The mask apparatus of any one of claims 1 to 3 wherein the cushion and the frame form a common plenum chamber for sealing about the nares and mouth.
5. The mask apparatus of any one of claims 1 to 4 wherein the cushion comprises a protrusion configured to ply adjacent to a nasal ala of the patient.
6. The mask apparatus of any one of claims 1 to 5 wherein the cushion comprises left and right nasal ala protrusions.
7. The mask apparatus of any one of claims 1 to 6 further comprising a cushion support clip, the cushion support clip configured to couple with the cushion and couple with the frame.
8. The mask apparatus of claim 7 wherein the cushion support clip comprises first and second opposing sides, and wherein the cushion support clip is configured to couple with the cushion on the first opposing side and to couple with the frame on the second opposing side.
9. The mask apparatus of either claim 7 or claim 8 wherein the cushion support clip comprises a nasal plateau region and a mouth periphery region.
10. The mask apparatus of claim 9 wherein the nasal plateau region is approximately perpendicular to the mouth periphery region.
11. The mask apparatus of claim 9 wherein the cushion support clip comprises a bend region between the nasal plateau region and the mouth periphery region, the bend region forming an approximately nasolabial angle between the nasal plateau region and the mouth periphery region.
12. The mask apparatus of claim 11 wherein the bend region comprises a set of inwardly directing nasal protrusions.
13. The mask apparatus of claim 12 wherein the nasal protrusions are flexible.
14. The mask apparatus of any one of claims 7 to 13 wherein the cushion support clip comprises first and second cushion support portions, the first and second cushion support portions being configured to provide different flexibility characteristics.
15. The mask apparatus of claim 14 wherein the first cushion support portion comprises a nasal support region and the second cushion support portion comprises a lateral mouth support region, the first cushion support portion having a higher rigidity characteristic with respect to the second cushion support portion.
16. The mask apparatus of any one of claims 1 to 15 wherein the sub-nasal ridge includes a scalloped edge.
17. The mask apparatus of any one of claims 1 to 16 wherein the cushion comprises a generally flat sealing surface.
18. The mask apparatus of any one of claims 1 to 16 wherein the cushion comprises a generally curved sealing surface.
19. The mask apparatus of any one of claims 1 to 18 further comprising a respiratory treatment apparatus configured to generate a controlled supply of a breathable gas at a pressure above atmospheric pressure, the respiratory treatment apparatus including a gas delivery conduit coupled with the frame to direct the breathable gas to the frame.
20. The mask apparatus of any one of claims 7 to 19, when dependent on claim 7,wherein the cushion support clip is flexible.
21. The mask apparatus of any one of claims 7 to 20, when dependent on claim 7, wherein the cushion support clip is inwardly concave.
22. The mask apparatus of any one of claims 7 to 21, when dependent on claim 7, wherein the cushion support clip is made of a material other than foam.
23. The mask apparatus of any one of claims 1 to 22 wherein the cushion is foam externally attached to flexible clip.
24. The mask apparatus of any one of claims 1 to 23 wherein a foam surface of the cushion is configured for direct contact with skin of a patient.
25. The mask apparatus of any one of claims 3 to 24, when dependent on claim 3, wherein the foam of the cushion is a semi-open cell foam with limited permeability.
26. A respiratory mask for delivering a respiratory gas treatment, the respiratory mask including a frame and cushion, the cushion adapted to couple with the frame, the cushion configured as a substantially under nose seal portion and a mouth seal portion, the cushion further defining a centrally open lip superior region.
27. The respiratory mask of claim 26 wherein the cushion comprises a nasal plateau region and a mouth periphery region, the cushion configured with an approximately nasolabial angle between the nasal plateau region and the mouth periphery region.
28. The respiratory mask of either claim 26 or claim 27 wherein the cushion comprises a triangular ring having a common nasal and mouth aperture.
29. The respiratory mask of any one of claim 26 to claim 28 wherein the cushion is foam.
30. The respiratory mask of any one of claim 26 to claim 29 wherein the cushion and the frame form a common plenum chamber for sealing about nares and mouth, the centrally open lip superior region being within the common plenum chamber.
31. The respiratory mask of any one of claim 26 to claim 30 wherein the cushion comprises a protrusion configured to ply adjacent to a nasal ala of a patient.
32. The respiratory mask of any one of claim 26 to claim 31 wherein the cushion comprises left and right nasal ala protrusions.
33. The respiratory mask of any one of claim 26 to claim 32 further comprising a clip to removably couple the cushion to the frame.
34. The respiratory mask of claim 33 wherein the clip comprises flexible nasal protrusions.
35. The respiratory mask of either claim 33 or claim 34 wherein the clip comprises a first and a second cushion support portions, the first and second cushion support portions being configured to provide different flexibility characteristics.
