Abstract: A full-face cushion for a patient interface that delivers breathable gas to a patient includes a frame connector adapted to engage the cushion with a mask frame. A clip is provided to maintain the cushion to the frame. The clip includes clip portions that connect to the frame with a snap-fit.

Abstract: A full-face mask assembly includes a frame, a cushion provided to the frame, the cushion adapted to form a seal around the patent's nose and mouth and a skeleton frame to maintain the cushion to the frame, the skeleton frame including at least one of an upper support member adapted to support a forehead support, lower headgear clip receptacles adapted to be engaged with clips provided to straps of a headgear assembly, and an annular elbow connection seal adapted to engage an inlet conduit.

Abstract: A patient interface for delivery of a supply of pressurised air or breathable gas to an entrance of a patient's airways including: a cushion member that includes a face contacting portion, a retaining structure and a resiliently flexible lip; and a frame member, wherein the retaining structure and the frame member are repeatedly engageable with and disengageable from one another, wherein a gas chamber is formed at least in part by engagement of the cushion member and the frame member, and wherein the resiliently flexible lip is configured to provide a sealing force between the cushion member and the frame member.

Abstract: 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.

Abstract: 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.

Abstract: A full-face cushion for a patient interface that delivers breathable gas to a patient includes a frame connector adapted to attach the cushion to a mask frame and an interface provided to the frame connector. The interface is constructed of foam and defines a cushion cavity. The interface includes a foam contact surface adapted to interface or contact with surfaces of the patient's face in use.

Abstract: A forehead support for a patient interface used in the treatment of sleep disordered breathing, includes a support post provided to a frame and a pair of arms extending from the support post. At least one of the pair of arms is adapted to rotate relative to the support post about an axis that extends transverse to the support post.

Abstract: A mask assembly includes a forehead support having a base provided to a frame and at least one, and preferably two upwardly extending support arms. The arms define a fixed or an adjustable included angle that is preferably less than 180° and, in the range of about 100°-150°. The arms can be attached either directly to headgear straps, or the arms can be connected to headgear straps via clips.

Abstract: 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.

Abstract: 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. The elbow has an exterior surface rotatable relative to a bearing surface formed on an inner circumferential surface of the opening, the elbow having an annular protrusion that abuts the frame of the cushion module when the distal end of the elbow is fully inserted into the opening. The retention structure maintains engagement between the shroud and the frame.

Abstract: A mask includes a shroud; a cushion module that engages the shroud, the cushion module including a frame and a full-face cushion adapted to engage the patient's face generally along nasal bridge, cheek, and chin regions of the patient's face, the frame at least partly defining a breathing chamber; an elbow connected to the frame in a releasable and rotatable manner, the elbow being adapted to be connected to an air delivery tube to deliver breathable gas to the patient; and headgear removably attachable to the shroud, wherein: the frame includes an opening, the elbow including a distal end releasably inserted into the opening of the frame with a snap-fit, thereby connecting the elbow to the frame, whereby the connection between the elbow and the frame also maintains the shroud in engagement with the frame.

Abstract: A full face mask system for treatment of respiratory disorder with Continuous Positive Airway Pressure equipment suitable to generate a supply of gas at positive pressure to be delivered to a patient's airways, the mask system comprising a frame module; a cushion module provided to the frame module and adapted to form a seal with the patient's face; an elbow module provided to the frame module and adapted to be connected to an air delivery tube to deliver breathable gas to the patient; and headgear removably attachable to the frame module.
