摘要：
A patient interface includes a frame, a cushion, and a reinforcing member. The cushion has a non-face-contacting portion connected to the frame and a face-contacting portion adapted to engage the patient's face in use. The face-contacting portion includes a side wall and a flexible membrane extending from the side wall. The reinforcing member is provided to at least a portion of an interior and/or exterior surface of the side wall of the cushion. The reinforcing member provides reinforcement to the side wall of the cushion to at least limit lateral expansion of the cushion in use. The reinforcing member may have a stiffness that is selectively varied along its length.
