Abstract
A sealing cushion for a respiratory mask assembly has a patient interface portion having a resiliently deformable membrane for engagement with a patient's face, and an aperture formed therein for receiving a nasal and/or mouth region of the patient's face. An inner surface of the deformable membrane comprises a plurality of projections arranged in separate groups of projections positioned in a plurality of localized regions of the deformable membrane. The projections in each of the separate groups of projections are arranged such that each projection in the group of projections engages with an adjacent projection in the group of projections when the deformable membrane is deformed during engagement of the deformable membrane with the patient's face, in use, thereby providing the deformable membrane with an increased resistance to further deformation.
