Abstract

A respiratory mask includes a frame and a flexible structure provided to the frame and adapted to engage a patient'"'"'s face. The flexible structure includes a chamber filled with a first gel and a second gel that is relatively harder than the first gel. A ratio of height of the first gel to the second gel in a lip region is in the range of about 0.25 to about 0.6.

Claims

19. A respiratory mask, comprising:

a frame; and

a flexible structure provided to the frame and adapted to engage a patient'"'"'s face, the flexible structure including a chamber filled with a first gel and a second gel that is relatively harder than the first gel, wherein a ratio of height of the first gel to the second gel in a lip region is in the range of about 0.25 to about 0.6.

20. A respiratory mask according to claim 19, wherein the first gel ranges in height in the lip region from about 4 mm to about 7 mm.

21. A respiratory mask according to claim 19, wherein the second gel ranges in height in the lip region from about 12 mm to about 15 mm.

22. A respiratory mask according to claim 19, wherein a ratio of height of the first gel to the second gel in a cheek region is in the range of about 0.5 to about 1.7.

23. A respiratory mask according to claim 22, wherein the first gel ranges in height in the cheek region from about 10 mm to about 15 mm.
