  • Patent number: 9592359
    Abstract: A respiratory mask assembly includes a respiratory mask including a mask shell and a mask cushion, a forehead support adjustably coupled to the mask, and an angular adjustment member. The forehead support includes a joining member provided to the mask shell and a cushion frame pivotally mounted to the joining member. The cushion frame is adapted to be selectively locked against pivotal movement in at least three predetermined angular positions relative to the joining member by a tongue and slot arrangement. The angular adjustment member allows relative angular adjustment between the cushion frame and the joining member. The angular adjustment member includes a pair of flexible arms that are adapted to be flexed towards one another to disengage the tongue from a respective one of the slots, and releasing the flexible arms allows the flexible arms to resiliently flex away from one another to engage the tongue and the respective slot.

  • Patent number: 8985117
    Abstract: A nasal assembly for delivering breathable gas to a patient includes a frame having an integrally formed first connector portion. A nozzle assembly includes a gusset or base portion and a pair of nozzles. At least one inlet conduit is structured to deliver breathable gas into the frame and nozzle assembly for breathing by the patient. A pair of second connector portions are removably and rotatably connected to respective first connector portions of the frame and are in communication with respective inlet conduits, e.g., directly or via angle connectors. A headgear assembly is removably connected to the pair of second connector portions and/or the angle connectors so as to maintain the frame and the nozzle assembly in a desired adjusted position on the patient's face.

  • Patent number: 8894231
    Abstract: A position sensitive illumination system for a patient includes an illumination source and at least one sensor structured and configured to selectively activate the illumination source in dependence of movement of the patient. Illumination source and/or sensor may be provided to one or more portions of a patient interface, e.g., a mask assembly, to thereby allow automatic activation of the illumination source when the patient moves to a predetermined position. Illumination source provides a directed lighted path for the patient as the patient moves about, e.g., during nocturnal visits to the bathroom, thereby avoiding the awakening of a bed partner.
