摘要：
A cushion for a patient interface that delivers breathable gas to a patient, the cushion comprising: a base wall (28)； and a face contacting portion (14) including a nasal bridge region (16), a pair of side of nose regions (17), a pair of upper cheek regions (18), a pair of a lower cheek regions (19), and a chin region (20). The face contacting portion is adapted to form a continuous seal on the patient&rsquo；s face in use. The portion of the cushion between the face contacting portion and the base wall of the cushion is structured and / or arranged to provide a spring configuration in the nasal bridge region, a spring configuration in the pair of side of nose regions, and a spring configuration in the chin region. In use, the spring configuration(s) permit displacement of the respective face contacting portions from an initial position in response to a frame force applied to the cushion, and resiliently move the respective face contacting portions towards the initial position when the frame force is released. The spring configuration in the nasal bridge region is more flexible than the spring configuration in the pair of side of nose regions. The spring configuration in the chin region is more flexible than the spring configuration in the pair of side of nose regions.
