Abstract
A patient interface includes a frame including a single sheet of textile material and a seal-forming structure provided to the frame. A first edge of the sheet of textile material is joined to a second edge of the sheet of textile material such that the frame adopts a predetermined three-dimensional shape that is maintained throughout the patient's respiratory cycle.
Claims28
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 including at least entrance of a patient's nares, wherein the patient interface is configured to maintain a therapy pressure in a range of about 4 cmH2O to about 30 cmH2O above ambient air pressure in use, throughout the patient's respiratory cycle, while the patient is sleeping, to ameliorate sleep disordered breathing,
- said patient interface comprising:
- a frame including a single sheet of textile material,
- wherein a first edge of the sheet of textile material is joined to a second edge of the sheet of textile material such that the frame adopts a predetermined three-dimensional shape that is maintained throughout the patient's respiratory cycle;
- and
- a seal-forming structure provided to the frame.
A method of manufacturing a patient interface suitable 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 including at least entrance of a patient's nares, wherein the patient interface is configured to maintain a therapy pressure in a range of about 4 cmH2O to about 30 cmH2O above ambient air pressure in use, throughout the patient's respiratory cycle, while the patient is sleeping, to ameliorate sleep disordered breathing,
- the method comprising:
- forming a textile sheet into a predetermined flat shape;
- connecting first and second edges of the textile sheet together to thereby form a frame from the sheet, wherein the frame defines, at least in part, a plenum chamber;
- and
- connecting a seal-forming structure to the frame.
