A nasal seal, mask or an interface assembly have a seal body defining a breathing chamber. A nasal port is provided in the seal body. The nasal port has a central portion straddled by a pair of lateral portions. The nasal port further has an upper edge and a lower edge. The upper edge defines an inwardly projecting portion within the central portion. The lower edge defines an inwardly protection portion within the central portion. Thus, the nasal port can be generally bean-shaped or bowtie-shaped. The mask can include a frame having a central portion that supports the seal and a pair of arm portions that extend rearwardly of the seal and are configured to connect to headgear. The central portion can be more rigid than the arm portions. The mask can be configured to reduce noise transmitted through a bias flow vent.

Nasal seal, mask and respiratory interface assembly

Frame for a nasal mask

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.

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 headgear system and/or an interface assembly incorporating a headgear system that, in some configurations, is configured to transform from elasticated or 'stretchy' behavior to “inelastic” behavior at least in response to normal or expected forces encountered during the intended therapy. In some configurations, upon fitment to the head of a user, the system automatically adjusts toward or to an appropriate size. A headgear portion or assembly for use in combination with a breathing apparatus in some configurations is at least substantially inelastic and is three dimensional in shape. The headgear portion or assembly can comprise a plastic core and a textile casing. The headgear, or part thereof, may also have integrally moulded labels, connectors, adjustment mechanisms and/or grips.

Headgear for a nasal mask

FIGS.-D &A-D disclose a large variety of methods of forming the headgear for use in combination with a breathing apparatus comprising a unitary plastic core within textile casings. In some configurations, the plastic core material penetrates or bursts-through the textile casing of the straps. Some configurations include over moulding, alignment posts, T-joints and joint housings with injection aperture. FIGS.-&A-C disclose a large variety of different headgear arrangements including top strap, front strap, rear strap and pairs of straps extending from the mask above and below the ear to meet behind the ear. FIGS.-B disclose a large variety of connectors connecting the headgear assembly to the mask assembly where the headgear, mask and connector form a closed loop the connector is disengaged with the mask assembly.
