A respiratory interface assembly includes a patient interface and a headgear arrangement. A seal or cushion of the interface assembly can include thickened portions positioned and arranged to improve sealing and/or user comfort. The headgear arrangement can be connectable to the nasal mask by a connection arrangement configured to provide stability to the nasal mask such that a forehead support is not required. The connection arrangement can inhibit or prevent improper connections. The headgear arrangement can have one or more resilient straps having a composite construction of an outer fabric and a plastic core. The outer fabric can be knitted. A rear portion of the headgear arrangement can include a knitted panel or a spacer fabric panel.

Respiratory interface assembly

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, 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

A respiratory mask for providing positive pressure therapy having ball jointed elbow, one or more detachable forehead pieces and headgear comprising a spacer fabric region is disclosed herein. The elbow is configured to be removable when oriented to a predetermined position. The forehead pieces are provided in one or more sizes. The spacer fabric region comprises two or more layers wherein the raw edges are turned to the inside of the layers. The seal comprises features that improves seal performance and accommodates a wider variety of facial geometries.

Cushion assembly for breathing mask assembly

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.

Nasal mask

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.

Interface comprising a rolling nasal bridge portion

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.

Nasal seal and respiratory interface

A respiratory mask for providing positive pressure therapy and a bias-flow venting system configured to reduce discernable draft generated by exhausted air are disclosed herein. The respiratory mask has a ball jointed elbow, one or more detachable forehead pieces and a headgear with a spacer fabric region. The elbow is configured to be removable when oriented to a predetermined position. The forehead pieces are provided in one or more sizes. The spacer fabric region having two or more layers wherein the raw edges are turned to the inside of the layers. The seal having improved seal performance and accommodating a wider variety of facial geometries. The bias-flow system having a tube and exhaust holes radially aligned on a bead of the tube. The bias-flow system also having an annular component exhaust holes and a shroud having a plenum chamber around the exhaust holes.
