Abstract: A patient interface can have a frame supporting a sealing member. Various features of the sealing member can improve comfort and sealing performance in the context of forming seals with the nares of a user, as well as contact with other facial surfaces. The sealing member can include convex portions, concave portions and thickness variations for providing various sealing, comfort, and deformability effects.

Abstract: A respiratory mask system comprising a mask interface comprising a frame for a headgear assembly. The frame comprises a body comprising a first surface and a substantially opposing second surface. The body further comprises a gas inlet and optionally an outlet vent. The gas inlet may be substantially elliptical in shape. The frame may comprise a recessed region for receiving a yoke of a headgear assembly to attach the headgear to the mask interface. The respiratory mask system may also comprise a yoke for attaching to the frame.

Abstract: FIGS. 1-16D & 66A-92D disclose a large variety of methods of forming the headgear for use in combination with a breathing apparatus comprising a unitary plastic core within textile casings. In some configurations, the plastic core material penetrates or bursts-through the textile casing of the straps. Some configurations include over moulding, alignment posts, T-joints and joint housings with injection aperture. FIGS. 17-65 & 93A-94C disclose a large variety of different headgear arrangements including top strap, front strap, rear strap and pairs of straps extending from the mask above and below the ear to meet behind the ear. FIGS. 95-121B disclose a large variety of connectors connecting the headgear assembly to the mask assembly where the headgear, mask and connector form a closed loop the connector is disengaged with the mask assembly.

Abstract: A respiratory mask includes a frame and a cushion module including a housing and a cushion that seals on a user's face in use. The housing includes a first connector, for example, a female connector, and the frame includes a second connector, for example, a male connector. The first and second connectors are coupled together in use. The housing includes one or more fasteners that secure the male connector to the female connector. Each fastener includes a base portion coupled to the housing and a moveable portion pivotally connected to the base portion. To assemble the mask, the male connector is inserted into the female connector such that the male connector engages the fasteners. Advancement of the male connector into the female connector causes the fasteners to change orientation from a neutral position to a toggled position and compress. The compressed fasteners apply a retention force to the male connector.

Abstract: A respiratory mask system includes a mask interface and a headgear assembly. The headgear assembly is adjustable and comprised of an elastic portion, a non-elastic portion and a restriction mechanism configured to provide a force resisting movement of the non-elastic portion when the elastic portion is extended. There is a support beam coupled to the non-elastic portion and extending along a portion of the headgear that is curved along its longitudinal extent. In this way particular seal modules can be comfortably fitted to a user and any blow off force is mitigated. A particular example of the respiratory mask system includes provision for removable attachment between the seal and a mask frame, the mask frame and a yoke of the headgear; and between a conduit and the mask frame.

Abstract: A headgear, for use in combination with a breathing apparatus, has a plastic or elastomer core and a fabric or textile casing. The headgear, or portions thereof, may also include a length adjustment arrangement that permits adjustment of a length of a section of the headgear. The length adjustment arrangement can comprise overlapping strap portions of the headgear. In some configurations, the overlapping strap portions can be covered by a sleeve. The sleeve can be secured to the headgear by overmolded end caps. A nasal respiratory interface can include a frame having a front surface, a rear surface, and an aperture extending from the front surface to the rear surface. The frame can have an oval form with a truncated height portion. The interface can also include a seal for a nasal pillow. The seal can be attached to the frame.
