  • Publication number: 20250235656
    Abstract: An interface for positive pressure therapy includes a mask assembly, a headgear assembly and a connection port assembly. The headgear assembly includes a component formed from two layers of 3D fabric folded. The mask assembly comprises a seal member that has an upper portion movably connected to an integrated lower portion, wherein the upper portion rolls during hinging movement of the upper portion relative to the lower portion. The headgear assembly allows connection to the mask assembly in a direction substantially normal to a direction of strap tension. The connection port assembly includes a swivel elbow with a valve member that controls flow through a port that opens toward the user. The valve member is provided with a tapered bead that helps prevent the valve member from sticking in a given position. Also, a connector for connecting a respiratory tube to an elbow connector.

  • Patent number: 12337114
    Abstract: A mask frame, comprises a central conduit connection aperture and lateral arms having a 3-D curvature. The lateral arms extend: outwardly from a center of the frame, rearwardly, towards the patients ears, and upwardly, along a vector passing from below the nose to a point between the temple the top of the ear. The lateral arms “twist” along their length, such that a bottom margin of an end of each lateral arm is positioned further away from a notional vertical plane passing through the centre of the conduit connection aperture than a top margin. Also provided is an anti-rotation feature which limits or prevents rotation between straps of a headgear, and the mask frame. Further provided is a buckle for a closed loop headgear the buckle being formed with a plurality of openings and posts configured to form an angled headgear strap path through the buckle through which part of a headgear strap loop can pass.

  • Publication number: 20240390630
    Abstract: A headgear for a respiratory mask has first and second straps configured to be connected to each other by first and second buckles. The straps are configured to overlap in a region that contacts the rear of a user's head. The overlapping regions of the first and second straps can be positioned in a bifurcated configuration to improve stability on a user's head. The first and second buckles can feature a glider end through which one of the first and second straps can slide and a strap attachment end to which the other strap is permanently connected. In some embodiments, the first and second buckles have two components that are pivotally connected to allow adjustment of the headgear size whilst in a bifurcated configuration.

  • Publication number: 20240358958
    Abstract: A headgear system and/or an interface assembly incorporating a headgear system that, in some configurations, is configured to transform from elasticated or “stretchy” behavior to “inelastic” behavior at least in response to normal or expected forces encountered during the intended therapy. In some configurations, upon fitment to the head of a user, the system automatically adjusts toward or to an appropriate size. A headgear portion or assembly for use in combination with a breathing apparatus in some configurations is at least substantially inelastic and is three dimensional in shape. The headgear portion or assembly can comprise a plastic core and a textile casing. The headgear, or part thereof, may also have integrally moulded labels, connectors, adjustment mechanisms and/or grips.

  • Patent number: 12102764
    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.
