A respiratory mask system comprising a mask interface comprising a frame for a headgear assembly. The frame comprises a body comprising a first surface and a substantially opposing second surface. The body further comprises a gas inlet and optionally an outlet vent. The gas inlet may be substantially elliptical in shape. The frame may comprise a recessed region for receiving a yoke of a headgear assembly to attach the headgear to the mask interface. The respiratory mask system may also comprise a yoke for attaching to the frame.

Respiratory mask system

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.

Patient interface and aspects thereof

A diffuser element for use over a vent opening of a breathing assistance apparatus. In some configurations, the diffuser element is formed by knitting or weaving one or more threads together into an interlocking pattern. In some configurations, the diffuser pad has a first surface and an opposing second surface and at least the first surface includes a surface texture. Arrangements for coupling the diffuser element to a structure that defines or carries the vent are also disclosed.

Diffuser arrangements for a vent of a respiratory interface

Frame of a nasal mask

Interfaces for positive pressure therapy having various vent designs are disclosed herein. The interfaces include a bias flow vent with design geometries that help reduce and/or minimize draft and noise levels of the fluids exiting the vents. Some of the vent designs include particular vent hole geometries, plenum spaces, diffusers and fibrous media.

Patient interface with venting

A respiratory mask system is provided. The respiratory mask system has a patient interface that is secured to a user's head by a headgear. The patient interface comprises a seal, a frame and a gas delivery conduit. The frame is configured to secure the seal and gas delivery conduit together. The frame comprises a recessed channel and/or headgear retaining features configured to connect the headgear to the patient interface. The frame can include an inlet collar that connects to a gas delivery conduit. The inlet collar can include bias flow holes. The headgear comprises a top strap, a pair of side arms, a yoke and a rear strap. The yoke is configured to connect to the recessed channel of the frame. The top strap, side arms and yoke form an integrally formed closed loop. The top strap can include two portions adjustably connected to each other.

Frame and headgear for respiratory mask system

Headgear and yoke assembly

A headgear, for use in combination with a breathing apparatus, has a plastic or elastomer core and a fabric or textile casing. The headgear, or portions thereof, may also include a length adjustment arrangement that permits adjustment of a length of a section of the headgear. The length adjustment arrangement can comprise overlapping strap portions of the headgear. In some configurations, the overlapping strap portions can be covered by a sleeve. The sleeve can be secured to the headgear by overmolded end caps. A nasal respiratory interface can include a frame having a front surface, a rear surface, and an aperture extending from the front surface to the rear surface. The frame can have an oval form with a truncated height portion. The interface can also include a seal for a nasal pillow. The seal can be attached to the frame.

Nasal respiratory interface and adjustable headgear

A patient interface includes a mask body, an elbow, a connector and a conduit. Any one or more of the mask body, the elbow, the connector and the conduit includes a bias flow vent. The bias flow vent is configured to deform with the application of pressure but not fully collapse such that an orifice size defined by the bias flow vent can vary with the application of pressure.

Pressure controlled exhaust vent

Seal

An interface assembly comprises a nasal mask that includes a seal having a rolling portion. The rolling portion of the seal rolls over a portion of a clip that secures the seal to a frame. The frame has a ball and socket connection to a connector. The connector comprises an elbow having integrally formed exhaust holes and a swivel.
