Patent number: 9132252Abstract: Systems, devices and methods of use adapted for treatment of respiratory disease or sleep disordered breathing include a patient interface (10) adapted to be secured to and sealed against a portion of a patient's face, in use. A flow generator is adapted to be connected to the patient interface and to be secured by a portion of the patient's body. The flow generator includes a blower (50) adapted to provide pressurized breathable gas to a patient through the patient interface. The blower is adapted to be at least partially vibrationally isolated from the patient's body by at least one dampening system (49) or device. The dampening device or system is adapted to reduce the amount of transmitted vibration received by the patient. A PAP system includes a patient interface including sealing arrangement (30) adapted to form a seal with the patient's nose and/or mouth and headgear (40) to support the sealing arrangement in position on the patient's head.Type: GrantFiled: August 27, 2010Date of Patent: September 15, 2015Assignee: ResMed LimitedInventors: Adam Barlow, Philippe Auguste Chalvignac, David Creusot, Aaron Samuel Davidson, Clementine Desvouyes, Gregory Phillip Dockar, Dmitri Anatolievich Doudkine, Justin John Formica, Timonty TsunFai Fu, Craig Edward Harris, Robert Edward Henry, Liam Holley, Ronald James Huby, Benjamin John Hunter, Barton John Kenyon, Philip Rodney Kwok, Dion Charles Chewe Martin, Frederick Arlet May, Michael Bruce Moir, Marco Mura, Jose Ignacia Romagnoli, Gerard Michael Rummery, David Brent Sears, Matthew David Spruell, James William Charles Vandyke, Roman Vinokur

Patent number: 8973576Abstract: A blower includes a housing including an inlet and an outlet, a stationary component provided to the housing, an impeller positioned between the inlet of the housing and the stationary component, and a motor adapted to drive the impeller. The housing and the stationary component cooperate to define a volute that directs air towards the outlet. The housing includes a separating wall constructed and arranged to divide the volute into a high speed airpath region and a low speed airpath region.Type: GrantFiled: November 19, 2010Date of Patent: March 10, 2015Assignee: ResMed Motor Technologies IncInventors: Barton John Kenyon, David Brent Sears, Aleksandr S. Nagorny, Michael Bruce Moir

Publication number: 20150023782Abstract: A flow generator includes a housing, a blower structured to generate a flow of pressurized breathable air, and a suspension device to support the blower within the housing and provide a pressure seal between low and high pressure sides of the blower. The suspension device includes a bellows-like portion provided along the perimeter of the blower to absorb shock applied at least radially to the blower and one or more cones provided along upper and/or lower sides of the blower to absorb shock applied at least axially to the blower.Type: ApplicationFiled: December 20, 2012Publication date: January 22, 2015Inventors: Allan Freas Velzy, Samuel Aziz Mebasser, Roman Vinokur, Kevin Gene McCulloh, Michael David Bednar, Karl Yutaka Iwahashi, David Brent Sears, Peter Jeffrey Thomas, Yeu-chuan Hsia, Hiroshi Suzuki, Benjamin An Shing Chao

Publication number: 20140283831Abstract: A control system (706) provides automated control of gas washout of a patient interface, such as a mask or nasal prongs. A gas washout vent assembly (60) of the system may include a variable exhaust area such as one defined by overlapping apertures of the assembly or a conduit having a variable gas passage channel. The vent assembly may be formed by nested structures, such as conic or cylindrical members, each having an opening of the overlapping apertures. The vent assembly may be attached substantially near or included with the patient interface. An actuator of the assembly, such as a solenoid or voice coil, manipulates an aperture of the vent assembly. The actuator may be configured for control by a controller to change the exhaust area of the vent assembly based on various methodologies including, for example, sleep detection, disordered breathing event detection, rebreathing volume calculation and/or leak detection.Type: ApplicationFiled: September 13, 2012Publication date: September 25, 2014Applicant: RESMED LIMITEDInventors: Roger Mervyn Lloyd Foote, Ronald James Huby, Muditha Pradeep Dantanarayana, Damien Julian Mazzone, Dion Charles Chewe Martin, Jeffrey Peter Armitstead, Justin John Formica, Zhuo Ran Tang, Lance Steven Cohen, James William Charles Vandyke, David Brent Sears, Aleksandr S. Nagorny, Joe Sampietro, Steven Paul Farrugia

Publication number: 20140069432Abstract: A blower includes a housing including an inlet and an outlet, a bearing-housing structure provided to the housing and adapted to rotatably support a rotor, a motor provided to the bearing-housing structure and adapted to drive the rotor, and an impeller provided to the rotor. The bearing-housing structure includes a bearing shaft having a bearing surface that rotatably supports the rotor. The bearing shaft provides only a single bearing of the non-ball bearing type for the rotor.Type: ApplicationFiled: April 18, 2012Publication date: March 13, 2014Applicant: RESMED MOTOR TECHNOLOGY INC.Inventors: Samuel Aziz Mebasser, Peter Jeffrey Thomas, Roman Vinokur, Kevin Gene McCulloh, William S. Lane, Yeu-chuan Hsia, Michael David Bednar, John Paul Freese, Karl Yutaka Iwahashi, David Brent Sears, Barton John Kenyon, Richard G. Krum, Par Egron Dannas, Hiroshi Suzuki, Malcolm Edward Leader

Publication number: 20140069428Abstract: A control system provides automated control of gas washout of a patient interface, such as a mask or nasal prongs. A gas washout vent assembly of the system may include a variable exhaust area, such as one defined by gears, radial exhaust revolvers and/or flow diverters for a conduit having a variable gas passage channel. The vent assembly may be attached substantially near or included with the patient interface. An actuator of the assembly, such as a solenoid, motor or voice coil, manipulates the vent assembly. The actuator may be configured for control by a processor to change the exhaust area of the vent assembly based on various methodologies including, for example, sleep detection, disordered breathing event detection and/or leak detection.Type: ApplicationFiled: August 15, 2013Publication date: March 13, 2014Applicant: RESMED LIMITEDInventors: David Brent Sears, Steven Paul Farrugia, Aleksandr S. Nagorny, Richard G. Krum, Joseph M. Sampietro
