Cushion for a patient interface
First Claim
Patent Images
1. A cushion for a patient interface comprising:
- an outer membrane providing a sealing structure adapted to form a seal with a patient'"'"'s face when the cushion is worn; and
an underlying membrane spaced away from the outer membrane, the underlying membrane providing a support structure for the outer membrane,wherein the outer membrane and the underlying membrane each have an inner edge which defines an aperture to receive the patient'"'"'s nose when the cushion is worn, the inner edge of the outer membrane and the inner edge of the underlying membrane are configured to conform to the patient'"'"'s face when the cushion is worn, and the underlying membrane is segmented along its inner edge to provide a set of independently flexible finger portion.

Abstract
A cushion for a patient interface includes an outer membrane providing a sealing structure adapted to form a seal with the patient'"'"'s face in use and an underlying membrane generally spaced away from the outer membrane. The underlying membrane provides a support structure for the outer membrane. The outer membrane and the underlying membrane each have an inner edge which defines an aperture to receive the patient'"'"'s nose in use. The underlying membrane is segmented along its inner edge.

13. A cushion adapted to be mounted on a frame of a patient interface for use with treatment of sleep disordered breathing, the cushion comprising:
-
an outer membrane; and an underlying membrane, the outer membrane being thinner than the underlying membrane and being spaced away from the underlying membrane and when the cushion is worn being adapted to contact a facial region of a patient, the underlying membrane having an inner edge defining an aperture and being divided along the inner edge to form a series of independently flexible finger portions, wherein the inner edge of the underlying membrane is configured to conform to the patient'"'"'s face when the cushion is worn. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21)

22. A cushion for a patient interface comprising:
-
a membrane; and an underlying membrane including an underlying support structure provided along a side of the cushion to support the membrane, the underlying support structure being segmented and configured to conform to a patient'"'"'s face when the cushion is worn, wherein the segmented underlying support structure provides a series of independently flexible portions along its perimeter that are structured to allow the cushion to conform to different patient facial profiles. - View Dependent Claims (23, 24)
