The ring also includes a plurality of vents configured to permit flow of gases from the interior to the exterior of the patient interface system. The swivel elbow and connector assembly includes an elbow swivelably secured in the ring. A patient interface system for delivering a flow of breathable gas to a user includes a patient interface structure configured to sealing engage the face of the user. The patient interface structure includes an aperture. A swivel elbow and connector assembly is sealingly secured in the aperture.

Abstract: A mask system for delivery of respiratory therapy to a patient includes a nares portion and a mouth portion and an inlet conduit connected to at least one of the nares portion and the mouth portion to deliver the pressurized, breathable gas. The mask system is adapted to selectively utilize the nares portion and/or the mouth portion in a first mode utilizing both the nares portion and the mouth portion, and in a second mode utilizing the nares portion and not utilizing the mouth portion.

Abstract: A patient interface includes a cushion configured to sealingly engage the patient's face, a support structure configured to support the cushion, the support structure being more rigid than the cushion, a plenum chamber formed at least in part by the cushion, and a connector configured to convey the pressurized respiratory gas to the plenum chamber. The connector includes a first portion formed from a first material and adapted to removably connect to the support structure. A plurality of vent holes are formed on the first portion. The connector also includes a continuous flexible portion that is formed from a second material, is more flexible than the first portion, and is configured to flex to permit engagement and disengagement of the first portion. The continuous flexible portion comprises a pair of opposing release buttons that are configured to be inwardly flexed to allow release of the connector from the support structure.

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.

Abstract: A nasal patient interface for delivery of a supply of pressurised air or breathable gas to an entrance of a patient's airways includes a cushion member that includes a retaining structure and a seal-forming structure permanently connected to the retaining structure, a frame member attachable to the retaining structure, and a positioning and stabilising structure releasably attachable to the frame member.

Abstract: A patient interface assembly includes an elastomeric piece configured to receive a flow of pressurized respiratory gas and sealingly engage the patient's face. The elastomeric piece forms a plenum and includes a mouth sealing portion, a nasal sealing portion, and an anterior surface with an air inlet opening configured to be coupled to a connector and/or an air delivery tube. The patient interface assembly also includes a stiffening structure that is attached to the anterior surface of the elastomeric piece. The stiffening structure comprises a central aperture that is sized so that the air inlet opening and a portion of the anterior surface surrounding the air inlet opening remain exposed through the central aperture. The stiffening structure is configured so that the entirety of the stiffening structure is inferior to the patient's nose in use.
