  • Exhaust assembly
    Patent number: 8573208
    Abstract: An exhaust assembly (1) adapted for use in a respiratory gas delivery system comprises an exhaust vent, an exhaust gas flow passage, a primary gas flow passage, and a moveable member. The exhaust gas flow passage communicated a flow of exhaust gas from a first end of the exhaust assembly to the exhaust vent. The exhaust vent communicates the exhaust gas from the exhaust gas flow passage to ambient atmosphere. The primary gas flow passage communicates a flow of supply gas from a second end of the exhaust assembly to the first end of the exhaust assembly. The moveable member defines at least a portion of the exhaust gas flow passage and the primary gas flow passage, is operable to isolate the flow of exhaust gas from the flow of supply gas, and is responsive to a pressure differential between the flow of supply gas and the flow of exhaust gas.

  • Magnetic coupling assembly and method of using same
    Patent number: 8573200
    Abstract: A magnetic coupling assembly for use in coupling portions of a gas deliver system. The magnetic coupling assembly includes a first member and a second member to be coupled together. The attractive forces between the first plurality of magnetic elements on the first member and a second plurality of magnetic elements on the second member join these member. The poles of magnetic elements in the first and second plurality of magnetic elements is opposite that of an adjacent magnetic element. The first and second members are easily detached from one another simply by rotating the first member relative to the second member such that the magnetic poles of the magnetic elements in each plurality of magnetic elements become unaligned, causing an weakening of the attractive forces.

  • PATIENT INTERFACE WITH FOREHEAD SUPPORT SYSTEM
    Publication number: 20130284178
    Abstract: A patient interface having a forehead support adjustably. The forehead support assembly includes a support arm that is adjustably mounted to the mask shell, thereby allowing the adjustment of the distance between the forehead support bracket and the mask shell in order to adjust for patients of different sizes. A forehead support bracket is pivotally connected to the support arm. The pivoting forehead support bracket is self-aligning to allow the forehead pad to remain parallel to the patient's forehead at all times, thus enhancing comfort and stability. The forehead support bracket is removable from the support arm, allowing the headgear (with support bracket attached) to be donned separately from the mask and support arm. The forehead support bracket in one embodiment has a forehead pad formed from the headgear itself.
