A shroud for a mask system includes a retaining portion structured to retain a frame, a pair of upper headgear connectors each including an elongated arm and a slot at the free end of the arm adapted to receive a headgear strap, and a pair of lower headgear connectors each adapted to attach to a headgear strap. The retaining portion, the upper headgear connectors, and the lower headgear connectors are integrally formed as a one piece structure.

A shroud () for a mask system includes a retaining portion structured to retain a frame (), a pair of upper headgear connectors () each including an elongated arm () and a slot () at the free end of the arm adapted to receive a headgear strap, and a pair of lower headgear connectors () each adapted to attach to a headgear strap. The retaining portion, the upper headgear connectors, and the lower headgear connectors are integrally formed as a one piece structure.

A mask system has a shroud module with headgear connectors adapted to removably attach to respective headgear straps of headgear; and a cushion module, including a frame defining a breathing chamber; and a cushion to form a seal with the patient's face in a nasal bridge region, a cheek region and a lower lip/chin region of the patient's face. The cushion is constructed of a first, relatively soft, elastomeric material and the frame is constructed of a second material that is more rigid than the cushion, and a nasal bridge portion of the cushion includes one or more folds to provide in use a higher level of adaptability or flexibility to the nasal bridge region of the cushion module relative to another region of the cushion module. The shroud module and the cushion module are configured to be removably coupleable to one another.

Mask system with shroud

A full-face mask system for delivery of a supply of gas at positive pressure to a patient for medical treatment includes a shroud, a cushion module adapted to form a seal with the patient's nose and mouth, an elbow, and headgear. The cushion module includes a frame and a cushion. The frame includes an opening that releasably receives a distal end of the elbow with a snap-fit, wherein an inner edge of the opening and the distal end of the elbow together form a retention structure to retain the elbow to the frame.

A cushion module provided to a frame module for delivery of a supply of gas at positive pressure to be delivered to a patient's airways, the cushion module comprising a main body and a cushion, the main body defining a breathing chamber and having an exterior surface adapted to directly engage with a surface of the frame module, wherein the main body and the cushion together comprise a co-molded, integrated component, the main body comprising a molded polycarbonate material adapted to directly contact the frame module and the cushion comprises a molded silicone material adapted to interface with patient's face, and wherein the molded polycarbonate material of the main body is a more rigid material than the molded silicone material of the cushion.
