  • 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.

  • Publication number: 20250235652
    Abstract: A respiratory mask includes a frame and a cushion module. The frame can include a front wall having a vent and/or a gas inlet opening and a collar extending away from the front wall. The collar surrounds the vent and/or the gas inlet opening. The cushion module comprises a cushion and a housing, which is made of a material more rigid than the cushion. The housing defines a connection opening. A friction coupling selectively couples the cushion module to the frame and comprises an elastomeric friction member coupled to a portion of the housing that defines the connection opening. In some arrangements, an outer surface of the friction member is exposed when the cushion module is coupled to the frame. In some arrangements, the housing extends through the peripheral surface.

  • Publication number: 20250195810
    Abstract: A mask assembly is provided comprising a cushion with a proximal face contacting portion, a distal inlet aperture, and a side wall between the proximal face contacting portion and the distal inlet aperture, a frame; and an inlet connector configured to connect to a source of pressurised gas. The frame comprises upper and lower headgear connectors both of which are below the cushion uppermost portion. The frame comprises a central connection portion removably connected to the cushion and the inlet connector. The central connection portion is relatively inflexible, whilst the remainder of the frame may be relatively flexible.

  • Publication number: 20240408342
    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.

  • Publication number: 20240293635
    Abstract: A respiratory interface assembly includes a patient interface and a headgear arrangement. A seal or cushion of the interface assembly can include thickened portions positioned and arranged to improve sealing and/or user comfort. The headgear arrangement can be connectable to the nasal mask by a connection arrangement configured to provide stability to the nasal mask such that a forehead support is not required. The connection arrangement can inhibit or prevent improper connections. The headgear arrangement can have one or more resilient straps having a composite construction of an outer fabric and a plastic core. The outer fabric can be knitted. A rear portion of the headgear arrangement can include a knitted panel or a spacer fabric panel.
