摘要：
A mask system for use between a patient and a structure to deliver a breathable gas to the patient includes a mask assembly including a frame, a cushion provided to the frame, and optionally an elbow provided to the frame. Headgear is removably attached to the mask assembly to maintain the mask assembly in a desired position on a patients face. The headgear includes a top strap, crown straps which cooperate to form a round shape adapted to accommodate a crown of the patients head, and bottom straps.
