    摘要: A respiratory mask having a flexible, mask seal portion for engagement with the face of a user, a gel forehead cushion and a rotatable elbow coupling having integral exhaust ports. The mask seal portion has a thin section which permits the mask to more easily adapt to the contour of the face of the user. The gel forehead cushion provides increased compliancy and resiliency to better adapt to multiple user physical profiles. The elbow coupling includes tapered through holes in a polycarbonate arc piece to provide a quiet passage of gas through the holes.
