Publication number: 20190232013Abstract: 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: July 2, 2015Publication date: August 1, 2019Applicant: ResMed LimitedInventors: 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
