  • Publication number: 20240399093
    Abstract: A patient interface to deliver a flow of air at a positive pressure with respect to ambient air pressure to an entrance to the patient's airways to ameliorate sleep disordered breathing includes a frame assembly and a cushion assembly configured to removably and repeatably connect to the frame assembly. The frame assembly and the cushion assembly form at least part of a plenum chamber pressurizable to a therapeutic pressure. The cushion assembly comprises a one-piece construction including a seal-forming structure configured to form a seal with a region of a patient's face surrounding the entrance to the patient's airways and a frame connection structure configured to removably and repeatably connect the cushion assembly to the frame assembly. The seal-forming structure comprises a first elastomeric material and the frame connection structure comprises a second elastomeric material, the first elastomeric material comprising a lower durometer or hardness than the second elastomeric material.

  • Publication number: 20160037272
    Abstract: A microphone module latching configuration for fixing a microphone module in a hearing instrument housing is formed at least partly of elastic material and has a planar extended basic shape, upper side, underside and a fixing device on the upper side to be brought into mutual, form-locking engagement with the microphone module, suppressing movement thereof relative to the latching configuration along its planar extent. A positioning device on the underside is brought into mutual, form-locking engagement with a microphone holder of the housing, suppressing movement of the latching configuration along its planar extent relative to the microphone holder, increasing structural freedom of the connection between latching configuration, microphone module and hearing instrument housing. The connection by fixing and positioning devices on the upper or underside eliminates a lateral holder or connection surrounding the microphone module, making the configuration slimmer.
