Patent number: 8439035Abstract: A flow regulation vent includes a fixed portion adapted to engage a gas supply conduit and a spring force biased movable portion connected by a hinge to the fixed portion and flowingly connected to the pressurized gas supply. The fixed portion includes a gas flow orifice. The movable portion is pivotally movable between 1) a relaxed position, whereby at a specified minimum operating pressure, the movable portion is pivoted by the spring force away from the fixed portion to a position to establish a first gas washout flow area between the movable portion and the gas flow orifice; and 2) a fully pressurized position, whereby at a specified maximum operating pressure, the pressurized gas offsets the spring force to pivot the movable portion to a position adjacent the fixed portion to establish a minimum gas washout flow area between the movable portion and the gas flow orifice.Type: GrantFiled: December 21, 2001Date of Patent: May 14, 2013Assignee: ResMed LimitedInventors: Muditha Pradeep Dantanarayana, Saad Nasr

Patent number: 8371302Abstract: A respiratory mask assembly for delivering breathable gas to a patient includes a frame having a front surface and a rear surface, opposite the front surface, and adapted in use to face the patient. The frame defines an inner wall and an outer wall extending from the rear surface, the inner and outer walls being spaced to define a channel therebetween. A cushion is removably attachable to the frame such that the cushion and frame are repeatably engagable with and disengagable from one another. The cushion includes a side wall to be inserted into the channel of the frame, the side wall having a first interlocking surface that engages a second interlocking surface provided in the channel when the cushion and frame are engaged with one another. The first and second interlocking surfaces interlock with one another to removably attach the cushion to the frame.Type: GrantFiled: May 26, 2010Date of Patent: February 12, 2013Assignee: Resmed LimitedInventors: Anthony Michael Ging, Saad Nasr, Philip Rodney Kwok, Rachael Elizabeth Moore, Andrew Martin Price
