Patent number: 11957835Abstract: An exchanger conduit permits temperature and/or humidity conditioning of a gas for a patient respiratory interface. In an example embodiment, a conduit has a first channel and a second channel where the first channel is configured to conduct an inspiratory gas and the second channel configured to conduct an expiratory gas. An exchanger is positioned along the first channel and the second channel to separate the first channel and the second channel. The exchanger is configured to transfer a component (e.g., temperature or humidity) of the gas of the second channel to the gas of the first channel. In some embodiments, an optional flow resistor may be implemented to permit venting at pressures above atmospheric pressure so as to allow pressure stenting of a patient respiratory system without a substantial direct flow from a flow generator of respiratory treatment apparatus to the patient during patient expiration.Type: GrantFiled: February 7, 2020Date of Patent: April 16, 2024Assignee: ResMed Pty LtdInventors: Liam Holley, Paul Jan Klasek, Robert Henry Frater, Quangang Yang, Pallavi Gosain

Publication number: 20230111767Abstract: A method of manufacturing a patient interface for sealed delivery of a flow of air at a continuously positive pressure with respect to ambient air pressure to an entrance to the patient's airways includes collecting anthropometric data of a patient's face. Anticipated considerations are identified from the collected anthropometric data during use of the patient interface. The collected anthropometric data is processed to provide a transformed data set based on the anticipated considerations, the transformed data set corresponding to at least one customised patient interface component. At least one patient interface component is modelled based on the transformed data set.Type: ApplicationFiled: December 8, 2022Publication date: April 13, 2023Applicant: ResMed Pty LtdInventors: Tzu-Chin YU, Aaron Samuel DAVIDSON, Robert Henry FRATER, Benjamin Peter JOHNSTON, Paul Jan KLASEK, Robert Anthony PATERSON, Quangang YANG, Gerard Michael RUMMERY, Priyanshu GUPTA, Liam HOLLEY, Gordon Joseph MALOUF

Publication number: 20220203058Abstract: Apparatus and methods provide control for generation of a flow of air to a patient's airways for different respiratory therapies. The pressure and a flow rate may be simultaneously controlled so as to provide a pressure therapy and a flow therapy. The system may include one or more flow generators, in which the control of the pressure and flow rate may include altering the output of one or more of the flow generators and/or an optional adjustable vent. The pressure and flow rate may each be held at a constant. One or both of the pressure and flow rate may also vary in accordance with a desired therapy. The air may be provided via a patient interface that includes a vent to atmosphere, which may be the adjustable vent. The vent may be actuated by a controller to implement the simultaneous control of pressure and flow rate of the air.Type: ApplicationFiled: March 18, 2022Publication date: June 30, 2022Applicant: ResMed Pty LtdInventors: Liam HOLLEY, Gordon Joseph MALOUF, Dion Charles Chewe MARTIN, Peter WLODARCZYK, Quangang YANG
