  • 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: 20250144351
    Abstract: A headgear assembly for a full-face under-nose respiratory mask can include a flexible headgear connector element. A free end of each of upper straps of the headgear is coupled to the headgear connector element, which is configured to extend laterally across and be removably fastened to a frame of the respiratory mask below a tip of a user's nose. A respiratory mask assembly can include a bias vent in communication with a cushion module and configured to allow air to be exhausted from the cushion module through the bias vent. The bias vent can be provided with a diffuser including a diffuser material configured to extend over the bias vent. The diffuser material provides a tortuous air path from the bias vent through the diffuser. The bias vent and/or the diffuser can be provided on various components of the assembly.
