  • Publication number: 20220211931
    Abstract: The invention relates to an ophthalmic pressure control system, comprising: a pressure regulator having an input port and an output port, and an infusion line having a proximal end and a distal end, the proximal end being connected to the output port of the pressure regulator, and the distal end being detachably connected to an ophthalmic irrigation module. Further, the system includes a control unit driving the pressure regulator for controlling an infusion fluid pressure at a distal end of the ophthalmic irrigation module. The control unit is arranged for performing a fluid calibration process including a step of determining a fluid impedance of the ophthalmic irrigation module. The infusion line is associated with a kit of parts including a first and a second ophthalmic irrigation device, or the ophthalmic irrigation module is an ophthalmic irrigation device for surgical use.

  • Patent number: 10034106
    Abstract: A hearing aid comprises a housing with a sound channel in a longitudinal direction and terminating in a sound opening, a transducer for transducing sound at the sound opening, and an insert member having an insert part for insertion into the sound channel and a support part arranged against the housing. The insert member forms a sound path from a first sound opening to a second sound opening. The first sound opening is arranged in the insert part and the second sound opening is arranged in the support part outside the sound channel. The insert part comprises a retention member for retaining wax. The retention member includes an opening and is arranged so that a part hereof extends transverse to the longitudinal direction. The support part forms a protruding engagement member which facilitates catching of the insert member without engaging the sound path during removal of the insert member.

  • Patent number: 10021472
    Abstract: A dome for a personal audio device. The dome forms a first flexible circumferential member and comprising a guiding structure extending in a longitudinal direction and forming an interface for guiding sound from or to the personal audio device. The guiding structure comprises a least one sound opening configured for passage of sound from or to the personal audio device in a direction transverse to the longitudinal direction of the guiding structure. The first flexible member is configured to at least partly close the sound opening during insertion of the dome into an ear canal of a user.
