Face mask cushion

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

An interface for positive pressure therapy includes a mask assembly and a headgear assembly. The mask assembly comprises a mask seal that is adapted to underlie the nose. The mask seal extends up the lateral sides of the nose. The mask seal has a primary seal below the nose and a secondary seal alongside the nose.

Valsalva mask

Headgear for a respiratory interface has multiple separate sections of material joined to form the headgear and different levels of resilient extensibility or stretchability in at least four different parts or straps of the headgear. The multiple separate sections of material can include a rear part, a pair of upper side straps, a pair of lower side straps, and a top strap.

Headgear

An interface for positive pressure therapy includes a mask assembly, a headgear assembly and a connection port assembly. The headgear assembly includes a component formed from two layers of 3D fabric folded. The mask assembly includes 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. 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.

Headgear for use with a patient interface

Headgear for a patient interface

A cushion for a respiratory mask is provided. The cushion includes a face contacting portion, a non-face contacting portion and an intermediate region. The face contacting portion is formed from an open cell foam material and includes an opening to provide, in use, a source of breathing gas to a user's airways. The non-face contacting portion is formed from an elastomeric material. The intermediate region is formed between the face contacting portion and the non-face contacting portion. Open cells of the open cell foam material in the intermediate region are filled with the elastomeric material.

Overmolded textile cushion

Cushion assembly for breathing mask assembly

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 assemblies and interface assemblies with headgear

A respiratory mask system includes a mask interface and a headgear assembly. The headgear assembly is adjustable and comprised of an elastic portion, a non-elastic portion and a restriction mechanism configured to provide a force resisting movement of the non-elastic portion when the elastic portion is extended. There is a support beam coupled to the non-elastic portion and extending along a portion of the headgear that is curved along its longitudinal extent. In this way particular seal modules can be comfortably fitted to a user and any blow off force is mitigated. A particular example of the respiratory mask system includes provision for removable attachment between the seal and a mask frame, the mask frame and a yoke of the headgear; and between a conduit and the mask frame.

A headgear assembly can include a pair of opposing, semi-rigid side arms. Each side arm can be pivotally coupled to an interface at a single location. Each side arm can extend from the single location across the user's cheeks and above the user's ears in use. The headgear assembly can include a top strap coupled to the pair of opposing, semi-rigid side arms, the top strap configured to extend around the top of a user's head. The headgear assembly can include a rear strap coupled to the pair of opposing, semi-rigid side arms, the rear strap configured to extend around the rear of a user's head. The headgear assembly can include a chin strap coupled to the pair of opposing, semi-rigid side arms, the chin strap configured to extend around the user's chin.

Headgear assembly with semi-rigid side arms

A respiratory mask system includes a headgear that, in use, secures the respiratory mask system to a patient's head. The headgear includes a pair of forehead straps that are coupled together by a forehead coupler to form a closed loop. The forehead coupler is removably connected to a frame of the respiratory mask such that the forehead straps remain in a closed loop. The pair of forehead straps can also be coupled together by positioning a male strap portion within an aperture of a female strap portion. The male strap portion has a free end that is configured to be received into the aperture. The male strap portion includes a plurality of notches that engage the aperture of the female strap portion and provide incremental adjustment. The free ends of the male and female strap portions have fasteners configured to engage the surface of the other strap portion.
