Abstract: One form of the present technology includes a sealing structure to seal against a user's face around the user's airways. The sealing structure includes a flap or membrane that extends inward towards the user's airways and includes a structure that prevents an inner boundary of the flap or membrane from being blown outwards (e.g., folded backwards upon itself) due to internal pressurization.

Abstract: Aspects of the present technology comprise a positioning and stabilising structure to hold a seal-forming structure in a therapeutically effective position on a head of a patient. The positioning and stabilising structure may comprise at least one gas delivery tube to deliver the flow of air to the entrance of a patient's airways via the seal-forming structure. The at least one gas delivery tube may be constructed and arranged to contact, in use, at least a region of the patient's head superior to an otobasion superior of the patient's head. The positioning and stabilising structure may comprise an adjustment mechanism for adjustment of a length of the at least one gas delivery tube to enable the positioning and stabilising structure to fit different size heads.

Abstract: A mask apparatus for a respiratory treatment can permit delivery of breathable gas to a user. In one example, the mask may employ a frame and cushion to form a seal for both mouth and nose. The frame may be adapted for coupling with a respiratory treatment apparatus so as to permit communication of a pressurized gas from the respiratory treatment apparatus. The cushion, which may be foam, may have a substantially under the nose configuration or over the nose configuration. The mask may have a common plenum chamber for both nose and mouth. The cushion may further define a centrally open lip superior region. The cushion may be adapted to couple with the frame directly or to the frame in conjunction with a cushion support clip. Various features of the cushion may further promote sealing and comfort for the under the nose design.

Abstract: A cushion assembly for a patient interface including an elastomeric seal-forming structure that is shaped to be bisected by a sagittal plane having a line that is tangent to the elastomeric seal-forming structure at a superior tangent point and at an inferior tangent point. A saddle-shaped superior region of the elastomeric seal-forming structure straddles the sagittal plane and includes the superior tangent point. The elastomeric seal-forming structure transitions in a cylinder-shaped superior region from the saddle-shaped region to a dome-shaped superior region offset from the sagittal plane. In addition, an elastomeric wall thickness of the elastomeric seal-forming structure is greater in the cylinder-shaped superior region than in the saddle-shaped superior region and the dome-shaped superior region.

In addition, for every point in the rigid support region, the inner surface has a negative curvature when the outer surface has a positive curvature and the inner surface has a positive curvature when the outer surface has a negative curvature.

Abstract: 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.

Abstract: A patient interface for delivering breathable gas to a patient includes a nasal prong assembly including a pair of nasal prongs structured to sealingly communicate with nasal passages of a patient's nose in use and headgear to maintain the nasal prong assembly in a desired position on the patient's face. The headgear includes side straps and rigidizers provided to respective side straps. Each rigidizer includes a first end portion that provides a connector structured to engage a respective end of the nasal prong assembly and an inwardly curved protrusion in the form of a cheek support that curves inwardly of the connector. The cheek support is adapted to follow the contour of the patient's cheek and guide a respective end portion of the side strap into engagement with the patient's cheek to provide a stable cheek support.
