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

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.

Frame and headgear for respiratory mask system

Headgear component for a nasal mask

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 for a nasal mask

A headgear assembly for retaining a respiratory mask on a user's face includes arrangements or components that allow for variation in a size of the headgear assembly. In some configurations, the headgear assembly includes one or more hubs, each of which are configured to connect a top and rear strap together. The size of the headgear assembly can be determined by the size or configuration of the hub. In other configurations, the headgear assembly comprises one or more spacer elements within one or more straps of the headgear. The size of the headgear assembly can be determined by the size of the spacer element or a relative position between the strap and the spacer element.

Headgear assembly

The apparatus, method, and system disclosed relates to a headgear assembly for a respiratory system for the delivery of respiratory therapy to a patient. The headgear comprises a yoke at least partially formed from an elastomeric material. The yoke is configured to be stretched under tension to attach the yoke to the headgear assembly.

Yoke for headgear

A nasal mask having a seal housing and a flexible nasal seal connected or connectable to the seal housing to define a mask cavity. The nasal seal extends between a face-contacting side and an outer side. The nasal seal has a contacting surface having an edge that defines a nose-receiving opening into the mask cavity and which is configured to seal about the user's nose. The nasal seal also has an under-nose support fixedly connected into the seal and which is configured to extend within the mask cavity and having a contact surface that is oriented to contact at least a portion of the under-nose surface of the user.
