摘要: A patient interface device includes a frame member and a cushion having a main body, a sealing portion, and first and second posts extending from the main body. The frame member defines a first orifice and a second orifice. The first post of the cushion is rotatably received within the first orifice and the second post is rotatably received within the second orifice in a manner that permits the cushion to rotate relative to the frame member.
