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 mechanism for releasing a mask from a patient's face includes a frame part including a male connection and a frame engagement portion for engaging a cooperating portion on a frame of the mask. A headgear part includes a female connection that is adapted to receive the male connection when the frame part is inserted into the headgear part, and a headgear engagement portion for engaging a cooperating portion on headgear of the mask. A cord has one end secured to the male connection, such that when the cord is pulled by the patient the male connection disengages from the female connection and consequently the frame part separates from the headgear part releasing the mask from the patient's face. A method of releasing a mask from a patient's face includes pulling a cord away from a frame of the mask to release a latch of the mask frame from a latch receiving portion of a headgear of the mask to release the latch from the latch receiving portion.
