Publication number: 20230356008Abstract: A headgear for use with a patient interface for delivering a flow of breathable gas to a patient includes at least a strap adapted to position the patient interface in sealing engagement with the patient’s airways. The strap is constructed from an elastomer and a first side of the strap includes a first region on a portion of its surface that is textured to reduce friction with objects contacting the strap. A textured surface coating for a portion of an elastomer strap included in a headgear system is adapted to contact the skin of a patient, when in use, and the coating has a Ra value greater than zero. A vent for use with a patient interface for delivering a flow of breathable gas to a patient includes a plurality of rises and runs in a stepped arrangement; and a plurality of holes in the stepped arrangement for the venting of gas.Type: ApplicationFiled: July 18, 2023Publication date: November 9, 2023Inventors: Gerard Michael RUMMERY, Robert Edward HENRY, Phoebe Katherine HILL, Andrew HURST, Philip Michael NURSE

Patent number: 11752367Abstract: A patient interface assembly is configured to deliver pressurized respiratory gas to a patient's airways. The patient interface assembly includes a cushion configured to sealingly engage the patient's face, a plenum base supporting the cushion, and a positioning and stabilizing structure configured to support the cushion and the plenum base on the patient's face. The positioning and stabilizing structure includes a stiffened portion. The patient interface assembly further includes a removable sleeve. The stiffened portion of the positioning and stabilizing structure is inserted into the removable sleeve. The removable sleeve is configured to be secured to the stiffened portion of the positioning and stabilizing structure by inserting a projection into a side cutout, and the stiffened portion of the positioning and stabilizing structure is prevented from sliding out of the removable sleeve when the projection is received within the side cutout.Type: GrantFiled: October 31, 2019Date of Patent: September 12, 2023Assignee: ResMed Pty LtdInventors: Gerard Michael Rummery, Robert Edward Henry, Phoebe Katherine Hill, Andrew Hurst, Philip Michael Nurse
