摘要：
A cushion for a patient interface that delivers breathable gas to a patient. The cushion includes a nasal bridge region, a pair of cheek regions and a chin region. The cushion defines a breathing cavity. The cushion has a membrane with a nasal bridge region, a pair of cheek regions and a chin region to form a continuous seal on the patient&rsquos face. The membrane defines an aperture adapted to receive the patient&rsquos nose and mouth. The cushion has a support structure to support the membrane. The support structure includes an underlying cushion to provide support to the membrane. The underlying cushion includes a left cheek region and a right cheek region. The underlying cushion and the membrane form double-walled construction in the pair of cheek regions of the cushion. A part of the chin region of the cushion does not include an underlying cushion.
