an intermediate maxilla support configured to be received within the recess of the mask, wherein the intermediate maxilla support comprises a plurality of air channels through the intermediate maxilla support; and
wherein the intermediate maxilla support is formed of a structural grid work in the form of a cross grid or latticework.
2. The positive airway supply system of claim 1 , wherein the intermediate maxilla support is removable.
3. The positive airway supply system of claim 1 , wherein the intermediate maxilla support comprises:
a support surface configured to interact with the portion of the maxilla between the nose and lips of the user; and
a malleable conforming material on the support surface.
4. The positive airway supply system of claim 3 , wherein the malleable conforming material is silicone.
5. The positive airway supply system of claim 1 , wherein the intermediate maxilla support is formed of a shape retaining polymer.
6. The positive airway supply system of claim 1 , wherein the intermediate maxilla support is coupled to an interior surface of the shell.
7. The positive airway supply system of claim 6 , wherein the shell comprises a structural grid work.
8. The positive airway supply system of claim 6 , wherein the intermediate maxilla support comprises a plurality of tabs configured to mate to a plurality of receivers on an interior surface of the shell.
9. The positive airway supply system of claim 1 , wherein the mask comprises a frame.
10. The positive airway supply system of claim 9 , wherein the intermediate maxilla support is attached directly to the frame.
11. The positive airway supply system of claim 1 , wherein the mask comprises a sealing membrane about the outer rim of the shell.
12. A positive airway supply system comprising:
a mask comprising:
a shell forming a recess, wherein the recess is configured to receive air from the positive air pressure source and the shell comprises
an outer rim;
a support frame about which the shell is formed; and
an intermediate maxilla support configured to be received within the recess of the shell and attached to the support frame,
wherein the intermediate maxilla support comprises a support surface configured to interact with the portion of the maxilla between the nose and lips of a user and a malleable conforming material on the support surface;
wherein the intermediate maxilla support is formed of a structural grid work in the form of a cross grid or latticework; and
a headgear or strap assembly attached to an outer surface of the shell.
13. The positive airway supply system of claim 12 , wherein the intermediate maxilla support is removable.
14. The positive airway supply system of claim 12 , wherein the intermediate maxilla support comprises a plurality of air channels through the intermediate maxilla support.
15. The positive airway supply system of claim 12 , wherein the intermediate maxilla support is formed of a shape retaining polymer.
16. The positive airway supply system of claim 12 , wherein the intermediate maxilla support is coupled to an interior surface of the shell.
17. The positive airway supply system of claim 12 , wherein the malleable conforming material is silicone.
18. The positive airway supply system of claim 12 , comprising a sealing membrane provided about the outer rim of the shell.
19. A positive airway supply system comprising:
a mask comprising:
a shell forming a recess, wherein the recess is configured to receive air from a positive air pressure source and the shell comprises
an outer rim;
a frame supporting the shell;
an intermediate maxilla support configured to be received within the recess of the shell, the intermediate maxilla support comprising:
a support surface;
a malleable conforming material on the support surface;
a plurality of air channels through the intermediate maxilla support;
a plurality of attachment components;
a plurality of complementary attachment components on an interior surface of the shell, wherein the plurality of attachment components are configured to mate to the plurality of complementary attachment components;
a sealing membrane about the outer rim of the shell;
a headgear or strap assembly; and
wherein the intermediate maxilla support is formed of a structural grid work in the form of a cross grid or latticework.
