Abstract: A patient interface has a single loop headstrap and a mask for covering at least the nostrils of the user. The single loop headstrap extends from the mask at either end. A short length of supple conduit is coupled to the mask by a swivel or ball joint to allow rotation of the conduit relative to the mask through different angles and orientations.

Abstract: A patient interface can have a frame supporting a sealing member. Various features of the sealing member can improve comfort and sealing performance in the context of forming seals with the nares of a user, as well as contact with other facial surfaces. The sealing member can include convex portions, concave portions and thickness variations for providing various sealing, comfort, and deformability effects.

Abstract: In one embodiment, a nasal cannula is shaped to fit within a user's nares, where the nasal cannula includes at least one prong allowing high flow delivery of humidified gases and creates positive airway pressure in the patient's airway. The prongs have angled ends such that, in use, gases flowing through the prongs are directed to the user's nasal passages. The nasal cannula body is partially swivelling and preferably has a ball joint connector. In another embodiment the nasal cannula may have at least one flared end prong that preferably seals within a patient's nare.

Abstract: An interface for positive pressure therapy includes a mask assembly, a headgear assembly and a connection port assembly. The mask assembly comprises a seal member that has an upper portion movably connected to an integrated lower portion, wherein the upper portion rolls during hinging movement of the upper portion relative to the lower portion. The headgear assembly allows connection to the mask assembly in a direction substantially normal to a direction of strap tension. The connection port assembly includes a swivel elbow with a valve member that controls flow through a port that opens toward the user.

Abstract: A nasal pillow section for use as part of an apparatus for providing a stream of gases to a user, the pillow section in use located in front of the upper lip and below the nostrils of a user, the pillow section comprising a pillow gasket having a gases aperture which receives a stream of gases in use, and nasal pillows fluidically connected to the pillow gasket which are adapted to substantially seal against the nostrils of a user in use, so that substantially the whole of the stream of gases entering the gasket through the aperture passes into the nasal pillows from the pillow gasket and is delivered to the user, the lower inner surface of the pillow gasket shaped so that in use contact between the upper lip of a user and the pillow gasket is minimised.

The connection port assembly includes a swivel elbow with a valve member that controls flow through a port that opens toward the user. The valve member is provided with a tapered bead that helps prevent the valve member from sticking in a given position. Also, a connector for connecting a respiratory tube to an elbow connector.
