Abstract
A flexible positive airway pressure (PAP) mask body, frame, and cushion are described. The mask body includes prongs that insert through and act upon apertures of the mask frame to connect the mask frame to the mask body. An airtight seal may be created between the mask body and the mask frame by a ball and socket connector, of the mask frame, having an elongated portion that extends through and has an outer perimeter commensurate with an aperture located in the mask body. The mask body may be configured with elongated portions that extend from the mask body chamber and to ends of eye sockets of the user. Headgear may couple to end portions of the mask frame corresponding to the elongated portions of the mask body. When pulling pressure by the headgear, additional contact is created between elongated portions of the mask cushion and the user's face.
