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 mask assembly can include a mask seal. In some configurations, the mask assembly can be configured to be fully positioned lower than a bridge of a nose of a face of a user and to provide an exposed bridge of the nose of the user. The mask seal can comprise a nasal region comprising at least one nasal opening, a first paddle on a first side of the nasal region and a second paddle on a second side of the nasal region. The first paddle is configured to contact one side of the nose of the user and the second paddle is configured to contact the other side of the nose of the user.

Patient interfaces

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

Frame for a mask assembly

In some embodiments there is provided a headgear assembly for a full-face under-nose respiratory mask comprising a strap assembly including a rear panel, a crown strap, a pair of opposing upper side straps, and a pair of opposing lower side straps. The assembly further comprises a flexible headgear connector element, wherein a free end of each of the upper straps is coupled to the headgear connector element, and wherein the headgear connector element is configured to extend laterally across and be removably fastened to a frame of the respiratory mask below a tip of a user's nose. There is also provided a respiratory mask assembly comprising a mask frame and a cushion module, the mask frame comprising a breathing gas inlet configured to receive a supply of breathable gas and to deliver the breathable gas to the cushion module, the cushion module being configured to form a seal with a user's face. The mask assembly can further comprise a bias vent in communication with the cushion module, and configured to allow air to be exhausted from the cushion module through the bias vent. the bias vent can be provided with a diffuser comprising diffuser material configured to extend over the bias vent, the diffuser material providing a tortuous air path from the bias vent through the diffuser. Embodiments are disclosed in which the bias vent and/or diffuser are provided on various components of the assembly.

Interface assemblies for respiratory therapy

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

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.
