Abstract:
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.

Claim (Index 1):
A rolling-bridge mask assembly to provide improved performance and comfort to a patient receiving respiratory therapy, the mask assembly comprising:\n a mask clip having a distal end, a proximal end, and a passage disposed at the distal end, at least a portion of the mask clip being formed of polycarbonate; a silicone mask seal having a mask seal distal end, a distal rim disposed at the distal end, a radiused portion, a reduced stiffness portion, a stiffer portion, a face contacting flange, and a hinge axis, the mask seal distal end being attached to the proximal end of the mask clip, the radiused portion extending outwardly from and transverse to the distal rim, and curving proximally towards a patient in use to the reduced stiffness portion, the reduced stiffness portion extending proximally from the radiused portion, the stiffer portion extending proximally from the reduced stiffness portion and having a greater stiffness than the reduced stiffness portion, the stiffer portion comprising a band extending across an apex of the silicone mask seal, the face contacting flange extending proximally from the stiffer portion and having an outer surface that is configured to lie flat over a bridge of a nose, outside of a mouth and below a lower lip of a patient in use; wherein the distal rim is disposed at a first radius from the hinge axis and the stiffer portion is disposed at a second radius from the hinge axis that is larger than the first radius, and wherein and the radiused portion and the reduced stiffness portion are configured to roll such that an outer surface of the radiused portion is rolled into juxtaposition with an outer surface of the distal rim when the face contacting flange is pivoted about the hinge axis and towards the distal end of the silicone mask seal so as to reduce a likelihood of the silicone mask seal encroaching into an interior of the mask assembly and to improve fitting to a variety of facial geometries while limiting pressure exerted against a sensitive bridge of a nose of the patient.
