Abstract

A ventilation mask having a cushioned facial interface and an adjustable support structure. The ventilation mask can have a gas delivery port with a gas delivery tube rotatably coupled thereto. The cushioned facial interface may have one or more interior membranes and an extended lower portion. The support structure may have an adjustable slide allowing a wearer to adjust the mask to increase comfort while maintaining a gas-tight seal between the mask and the face of the wearer.

Claims

1. A ventilation mask, comprising:

an outer body including at least one gas entry port to be connected to a source of breathable gas;

a cushion connected to the outer body about a perimeter, the cushion forming a gas-tight seal with the outer body, and further having;

at least one interior membrane;

a chin portion that extends below the outer body;

and a chin flap coupled to a distal end of the chin portion and extending toward the at least one gas entry port such that the chin flap is positioned adjacent the chin portion and oriented substantially parallel thereto, wherein the chin flap facilitates providing chin support and has a single surface that facilitates providing a seal against a face and under the chin of a wearer; and

an upper portion adjustably secured to the outer body and having a forehead cushion.

2. The ventilation mask of claim 1, wherein the upper portion is formed as one piece and that can be adjusted vertically.

3. The ventilation mask of claim 1, further comprising a deformable link connecting the upper portion to the outer body.

4. The ventilation mask of claim 3, further comprising a slot in the deformable link configured to facilitate deformation of the link.

5. The ventilation mask of claim 3, further comprising at least one hole in the deformable link to facilitate securing the deformable link to the upper portion.

6. The ventilation mask of claim 1, wherein the upper portion can be adjusted fore and aft.

7. The ventilation mask of claim 6, wherein the upper portion has a 180 degree range of fore and aft motion.

8. The ventilation mask of claim 1, wherein the upper portion can be adjusted laterally.

9. The ventilation mask of claim 8, wherein the upper portion has a 90 degree range of lateral motion.

10. The ventilation mask of claim 1, wherein the upper portion can be adjusted vertically.

11. The ventilation mask of claim 10, wherein the upper portion has a range of motion of at least 0.100″

.

12. The ventilation mask of claim 10, wherein the upper portion is adjusted through the use of a lever.

13. The ventilation mask of claim 1, wherein the angle of the upper portion can be adjusted.

14. The ventilation mask of claim 13, wherein the upper portion has a 180 degree range of motion.

15. The ventilation mask of claim 1, wherein the chin portion of the cushion extends below the perimeter.

16. The ventilation mask of claim 1, wherein the at least one membrane comprises two membranes that provide a seal between the cushion and a wearer of the mask.

17. The ventilation mask of claim 1, wherein the cushion has at least two membranes on a first side of the cushion and at least two membranes on a second side of the cushion.

18. The ventilation mask of claim 1, wherein the cushion has one membrane at the top of the cushion and one membrane at the bottom of the cushion.

19. The ventilation mask of claim 1, wherein a gas delivery tube is rotatably engaged in the at least one gas entry port.

20. A ventilation mask, comprising:

an outer body;

a gas delivery tube;

a gas delivery port;

a cushioned facial interface connected to the outer body about a perimeter, comprising;

at least one interior membrane,

a chin portion that extends below the outer body; and

a chin flap coupled to a distal end of the chin portion and extending toward the gas delivery port such that the chin flap is positioned adjacent the chin portion and oriented substantially parallel thereto, wherein the chin flap facilitates providing chin support and has a single surface that facilitates providing a seal against a face and under the chin of a wearer;

a support structure; and

an adjustable upper portion having a forehead cushion;

the gas delivery tube rotatably connected to the outer body at the gas delivery port and creating a seal therebetween, the cushioned facial interface removably connected to the outer body and creating a seal therebetween, and the adjustable upper portion connected to the support structure.

21. The ventilation mask of claim 20, wherein the adjustable upper portion may be deformed to adjust the fit of the support structure.

22. The ventilation mask of claim 20, wherein the adjustable upper portion is adjustable fore, aft, vertically, horizontally and rotationally.

23. The ventilation mask of claim 20, wherein the cushioned facial interface has an extended lower portion.

24. The ventilation mask of claim 20, wherein the cushioned facial interface has a first membrane on a top portion of the cushioned facial interface, a first membrane on the bottom portion of the cushioned facial interface, and a first membrane and a second membrane on a first side of the cushioned facial interface and a first membrane and a second membrane on a second side of the cushioned facial interface.

25. The ventilation interface of claim 20, further comprising at least one post for the attachment of headgear.

26. The ventilation interface of claim 20, wherein the cushioned facial interface is formed out of silicone.

27. The ventilation interface of claim 20, wherein the outer body has at least one exhaust port.

28. A cushion for a ventilation mask, comprising:

a first side having a first and second membrane;

a second side having a first and second membrane;

a top portion having only a first membrane; and

a chin portion and a chin flap coupled to a distal end of the chin portion;

the first side, second side, top portion and chin portion forming a gas tight seal between the cushion and a ventilation mask wherein the chin flap extends outwards from the cushion such that the chin flap is positioned adjacent the chin portion and oriented substantially parallel to the chin portion to facilitate providing support for the ventilation mask and wherein the chin flap has a single surface to facilitate providing a seal against a face and under a chin of a wearer.

29. The cushion of claim 28, wherein the cushion forms a gas tight seal between the cushion and the face of the wearer.
