Publication number: 20230098579Abstract: Apparatus and methods automate selection of patient interface(s). Image data captured by an image sensor may contain facial feature(s) of a user. The facial features may be captured in association with a predetermined reference feature of known dimension(s) such as with a user interface display that is generated with a sequence of icons that are activated for directing and tracking movement within the interface for desired image capture. The user's facial feature(s) and the reference feature may be detected in the captured image data. The image may be processed to measure an aspect of the detected facial feature(s) based on the reference feature. A patient interface size may be detected from standard patient interface sizes based on a comparison between the measured aspect of the facial feature(s) and a data record relating sizing information of the standard patient interface sizes and the measured aspect of the facial feature(s).Type: ApplicationFiled: September 21, 2022Publication date: March 30, 2023Applicant: ResMed Pty LtdInventors: Michael Christopher HOGG, Rowan Ben FURLONG, Nicholas James MEALEY, Kristina Mira ZLOMISLIC, Paul Andrew DICKENS

Publication number: 20230077034Abstract: An oxygen concentrator 100 apparatus and a method thereof implement operations control to efficiently release oxygen enriched gas to reduce potential waste. The control methodology may include generating a profile such as a minimum inhalation flow profile of the user. The profile may be based on a size parameter of the user. The method may determine one or more control parameters characterizing a bolus of oxygen enriched gas based on the generated flow profile. The control methodology may then generate a bolus release control signal, such as for a supply valve, according to the determined one or more control parameters. The oxygen concentrator may then, with the control signal, release and deliver a bolus of oxygen enriched gas for a user such as for reducing waste.Type: ApplicationFiled: August 11, 2022Publication date: March 9, 2023Applicants: ResMed Pty Ltd, RESMED PARIS SASInventors: Paul Andrew DICKENS, Dion Charles Chewe MARTIN, Olivier TESSIER, Peter WLODARCZYK

Publication number: 20220160979Abstract: Apparatus, such as a respiratory therapy device 4000, may generate a signal representing an estimate of a patient breathing pattern when using a flow therapy device with an un-sealed patient interface. The device may include a blower and may generate a flow of air at a controlled flow rate. The apparatus may include a controller. The generation may involve computing an estimate of the breathing pattern as a function of a device flow rate signal; a device pressure signal; a device conductance; a patient conductance; and a coupling parameter that characterizes a degree of coupling between the interface and the patients nares. An estimate of an exit pressure representative of a pressure of a flow of air generated by the therapy device just outside an orifice of the unsealed interface may also be computed. An estimate of a flushing flow rate from the estimated exit pressure may also be computed.Type: ApplicationFiled: April 9, 2020Publication date: May 26, 2022Applicant: ResMed Pty LtdInventors: Paul Andrew DICKENS, Dion Charles Chewe MARTIN

Publication number: 20210346634Abstract: Apparatus and methods provide operations for a respiratory disorder therapy by generating a flow or pressure therapy with supplementary oxygen. The method may be implemented by one or more processors that may set one or more therapy parameters associated with generating a flow of air to a patient interface via an air circuit. The one or more processors may set one or more supplementary oxygen parameters associated with introducing supplementary oxygen into the flow of air at the air circuit. The method may involve computing an oxygen performance metric associated with characteristic(s) of a patient and the air flow with the supplementary oxygen. The computing may include applying function(s) comprising the therapy parameter(s) and supplementary oxygen parameter(s). Output, such as a display indicator or automated therapy control change(s), may be generated using the computed oxygen performance metric. Changes to therapy parameter(s) may be made to optimise the metric.Type: ApplicationFiled: August 23, 2019Publication date: November 11, 2021Applicant: ResMed Pty LtdInventors: Dion Charles Chewe MARTIN, Paul Andrew DICKENS
