Patent number: 7753050Abstract: A respiratory mask assembly for delivering breathable gas to a patient includes a frame and at least one locking clip. The frame has a main body and a side frame member provided on each lateral side of the main body, at least one of the side frame members including a locking clip receiver assembly. The at least one locking clip has a main body providing a front portion adapted to be removably coupled with the at least one locking clip receiver assembly and a rear portion adapted to be removably coupled to a headgear assembly. The rear portion includes a cross bar that forms an opening through which a strap of the headgear assembly can pass and be removably coupled with the cross bar, and the front portion includes at least one resiliently flexible spring arm that is flexible within the plane of the main body.Type: GrantFiled: September 5, 2003Date of Patent: July 13, 2010Assignee: ResMed LimitedInventors: Perry D. Lithgow, Memduh Guney, Amal S. Amarasinghe, Timothy Tsun-Fai Fu, Gary C. Robinson, Aaron Samuel Davidson, Milind Chandrakant Raje

Publication number: 20100132717Abstract: A breathing arrangement includes a patient interface, at least one inlet conduit, and a headgear assembly. The patient interface includes a mouth covering assembly including a cushion structured to sealingly engage around exterior of a patient's mouth in use, a nozzle assembly including a pair of nozzles structured to sealingly engage within nasal passages of a patient's nose in use, and an element connecting the mouth covering assembly and the nozzle assembly. The at least one inlet conduit is structured to deliver breathable gas into at least one of the mouth covering assembly and the nozzle assembly for breathing by the patient. The headgear assembly is removably connected to at least one of the mouth covering assembly and the nozzle assembly so as to maintain the mouth covering assembly and the nozzle assembly in a desired position on the patient's face.Type: ApplicationFiled: February 5, 2010Publication date: June 3, 2010Applicant: ResMed LimitedInventors: Aaron Samuel DAVIDSON, Michael Kassipillai Gunaratnam, Susan Robyn Lynch, Milind Chandrakant Raje, Gary Christopher Robinson, Steven John Lubke, Gregory Scott Smart, Philip Rodney Kwok, Rupert Christian Scheiner

Publication number: 20090194111Abstract: An elbow for a mask system includes a proximal end adapted to be provided to the mask system, a distal end adapted to be provided to an air delivery conduit, and a baffle provided within the proximal end. The baffle has a generally planar configuration that defines an intake port that directs incoming air from the air delivery conduit into a mask cavity and an exhaust port separated from the intake port that directs exhaust air from the mask cavity to atmosphere. The baffle includes an end portion that is adapted to extend into the mask cavity defined by the mask system.Type: ApplicationFiled: May 19, 2006Publication date: August 6, 2009Applicant: ResMed LimitedInventors: Timothy Tsun-Fai Fu, Daniel Robert Judson, Aaron Samuel Davidson, Daniel Joseph Kaars Sijpesteijn, Amal Shirley Amarasinghe, Jim Saada, Milind Chandrakant Raje, Sarah Dane

Patent number: 7406965Abstract: A respiratory mask assembly includes a frame and a forehead support secured to the frame. The forehead support includes a joining member secured to an upper portion of the frame and a cushion frame movably mounted to the joining member. One of the joining member and cushion frame includes a pair of shafts and the other of the joining member and cushion frame includes a pair of openings. The pair of shafts are respectively received in the pair of openings to couple the cushion frame to the joining member and enable the cushion frame to move relative to the joining member. Each of the shafts has a non-circular cross section defining a major longitudinal axis that is angled forwardly of a vertical axis of one of the joining member and cushion frame so as to angle toward a front portion of one the joining member and cushion frame.Type: GrantFiled: May 5, 2004Date of Patent: August 5, 2008Assignee: ResMed LimitedInventors: Philip R. Kwok, Milind Chandrakant Raje, Aaron Samuel Davidson

Patent number: 7318439Abstract: A respiratory mask assembly for use in the delivery of non-invasive positive airway pressure to a user. The assembly includes a rigid shell having a channel portion defined by an inner wall, an outer wall and a channel floor, a face-contacting cushion acting to space the shell away from the user's face and a sealing tab extending from the cushion to engage a portion of the shell to provide a continuous airtight seal between the cushion and the shell. A retaining ring within the mask assembly is configured to secure the cushion to the shell. The retaining ring has a first portion including at least one clip configured to pass through at least one slot portion such that an underside surface of the at least one clip engages a section of the shell when the retaining ring is positioned within the channel.Type: GrantFiled: October 12, 2004Date of Patent: January 15, 2008Assignee: ResMed LimitedInventors: Milind Chandrakant Raje, Timothy Tsun-Fai Fu, Amal Shirley Amarasinghe, Joanne Elizabeth Drew, Robert Henry Frater, Memduh Guney, Clive Solari

Patent number: 7260440Abstract: A system and method for measuring contact pressures between two surfaces, and especially, between the body and a device resting on the body, e.g., the skin and a breathable gas mask. A deformable, resilient probe having a flow passage therein is initially placed between the two surfaces such that the flow passage is blocked. Fluid pressure within the probe is then increased until the pressure in the probe overcomes the contact pressure between the two surfaces, such that fluid begins to flow through the flow passage in the probe. The pressure at which the fluid begins to flow through the flow passage in the probe is recorded as the contact pressure between the two surfaces. Contact pressure maps created using this apparatus and method may be used to create anthropometric models of the face and other body parts.Type: GrantFiled: July 29, 2005Date of Patent: August 21, 2007Assignee: ResMed LimitedInventors: Andrew Selim, Patrick John McAuliffe, Milind Chandrakant Raje, Robert Henry Frater
