Publication number: 20230405368Abstract: A personal entertainment respiratory apparatus provides air to a user to provide a fully immersive entertainment experience. The personal entertainment system may comprise a flow generator for providing the flow of air. A personal spatial respiratory interface may be coupled to the flow generator. The personal spatial respiratory interface may comprise an outlet for the flow generator. The personal spatial respiratory interface may further be configured to direct the flow of air within an ambient breathing proximity of a user. The personal entertainment respiratory apparatus may further comprise a controller and a sensory particle dispenser. The controller and sensory particle dispenser may be configured to selectively activate release of a sensory particle from the dispenser into the directed flow of air in response to an entertainment triggering signal.Type: ApplicationFiled: May 11, 2023Publication date: December 21, 2023Applicant: ResMed Pty LtdInventors: Tzu-Chin YU, Emma Anne Connell, David Creusot, Donald Darkin, Barton John Kenyon, Paul Jan Klasek, Andrew Sims, Quangang Yang, Phillip Rodney Kwok

Patent number: 11730909Abstract: A conduit for delivering a supply of gas under a positive pressure includes a conduit wall having a first conduit end and a second conduit end. The first conduit end is adapted to be attached to the supply of gas. The conduit wall is deformable between (a) an open condition in which the conduit wall defines a conduit passage along which the supply of gas can travel between the first conduit end to the second conduit end, and (b) a collapsed condition in which the conduit wall substantially collapses the conduit passage.Type: GrantFiled: June 12, 2020Date of Patent: August 22, 2023Assignee: ResMed Pty LtdInventors: Philip Rodney Kwok, Donald Darkin

Publication number: 20230073790Abstract: A mask cushion or a mask assembly therewith provides a comfortable and effective seal for provision of a gas therapy by a respiratory treatment apparatus. The mask cushion may be integrated with or coupled to a mask frame. The mask cushion typically includes an inner cushion component. The mask cushion also includes a patient facial-contact side portion with a chamber and a barrier to form the chamber that may be flexible. The chamber may serve as an outer layer with respect to the inner cushion component. The chamber may be partially or completely filled with a gas, fluid or gel. The inner cushion may be formed with a soft flexible material such as an elastomer or foam, etc. The barrier may be a membrane and may also be soft flexible material.Type: ApplicationFiled: July 20, 2022Publication date: March 9, 2023Applicant: ResMed Pty LtdInventors: Daniel Robert Judson, Justin John Formica, Renee Frances Flower, Donald DARKIN, Phillip Rodney KWOK, Grant Moiler, David Anthony Pidcock, Gregory Robert PEAKE, Aaron Samuel DAVIDSON, Damien Julian Mazzone

Patent number: 11583652Abstract: 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.Type: GrantFiled: December 15, 2021Date of Patent: February 21, 2023Assignee: ResMed Pty LtdInventors: Michael Kassipillai Gunaratnam, Philip Rodney Kwok, Robin Garth Hitchcock, Lee James Veliss, Memduh Guney, Richard Sokolov, Perry David Lithgow, Donald Darkin, Susan Robyn Lynch

Patent number: 11529489Abstract: A respiratory mask assembly for delivering breathable gas to a patient includes a frame and a cushion. The cushion has a non-face contacting portion structured to be connected to the frame, a face-contacting portion structured to engage the patient's face, and a central portion that interconnects the non-face contacting portion and the face contacting portion. The frame may be structured to allow a forehead support to assume multiple positions, to compensate for replacement cushions that may have a different profile, shape or size. The cushion is structured to compensate for variations in strap tension, treatment pressure and/or movement of the patient. Headgear may be provided with a strap assembly in which one or more straps is provided with selectively adjustable elasticity or extensibility that may be automatically changed in dependence of treatment pressure and/or treatment type.Type: GrantFiled: July 9, 2021Date of Patent: December 20, 2022Assignee: ResMed Pty LtdInventors: Robert Henry Frater, Joanne Elizabeth Drew, Philip Rodney Kwok, Patrick John McAuliffe, Aaron Samuel Davidson, Robin Garth Hitchcock, Michael Kassipillai Gunaratnam, Donald Darkin, Gary Christopher Robinson
