Abstract

The present disclosure relates to a facial mask system having an internal intermediate maxilla support structure for providing increased support and decreased occurrence of points having increased pressure concentration on a user'"'"'s face, where the maxilla support system provides a comfortable, uniform sealing force around the breathing passages of a user.

Claims

1. A positive airway supply system comprising:

a positive air pressure adapter being configured to connect to a positive air pressure source;

a mask comprising;

a shell forming a recess, wherein the recess is configured to receive air from the adapter; and

an outer rim adapted to seal around the mouth and nose of a user; and

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.
