Abstract: An air delivery conduit includes first and second conduit portions that cooperate to form the conduit, each conduit portion including an inner layer of a film laminate that forms an interior surface of the conduit and an outer layer of a textile that forms an exterior surface of the conduit.

Abstract: A patient interface to deliver a flow of air at a positive pressure with respect to ambient air pressure to an entrance to the patient's airways to ameliorate sleep disordered breathing includes a frame assembly and a cushion assembly configured to removably and repeatably connect to the frame assembly. The frame assembly and the cushion assembly form at least part of a plenum chamber pressurizable to a therapeutic pressure. The cushion assembly comprises a one-piece construction including a seal-forming structure configured to form a seal with a region of a patients face surrounding the entrance to the patients airways and a frame connection structure configured to removably and repeatably connect the cushion assembly to the frame assembly. The seal-forming structure comprises a first elastomeric material and the frame connection structure comprises a second elastomeric material, the first elastomeric material comprising a lower durometer or hardness than the second elastomeric material.

Abstract: A neck strap, a crown strap assembly and a headgear for a breathing mask. The neck strap for a headgear includes a one-piece main body adapted to engage a patient's neck, first and second lower connection portions adapted to connect to first and second lower mask connection straps, and first and second upper connection portions adapted to connect to respective first and second lateral crown straps.

Abstract: A patient interface includes a frame including a textile material and a seal-forming structure provided to the frame. The seal-forming structure includes a foam material and/or a foam and textile material configured and arranged to form a seal with the patient's nose and/or mouth.

Abstract: A patient interface system to treat sleep disordered breathing of a patient with pressurized gas, comprising: a patient interface; at least one strap; at least one retractor fixedly attached to the patient interface, said at least one retractor connected to the at least one strap and configured to retract the at least one strap without patient actuation; and at least one pad to cushion a rearward portion of the patient's head, said at least one pad having an opening, wherein said at least one strap passes through said opening to allow the at least one pad to move freely relative to said at least one strap.

Abstract: A headgear or headgear segments are manufactured to shape thereby producing little or no waste material. Such headgear or headgear segments (components) may comprise a unitary, substantially seamless structure. Techniques such as knitting, braiding, crocheting, and 3D printing may be used to produce the headgear. As a result, the manufacturing process may have reduced steps, the amount of material waste may be reduced, and there are virtually no seams in the headgear between adjoining sections, thereby resulting in headgear with enhanced comfort.

Abstract: A patient interface for sealed delivery of a flow of air at a continuously positive pressure with respect to ambient air pressure to an entrance to the patient's airways including at least entrance of a patient's nares to ameliorate sleep disordered breathing may include a seal-forming structure comprising a foam undercushion and a textile membrane for contact with the patient's face; a positioning and stabilising structure to maintain the seal-forming structure in sealing contact with an area surrounding an entrance to the patient's airways while maintaining a therapeutic pressure at the entrance to the patient's airways; and a plenum chamber pressurised at a pressure above ambient pressure in use.

Abstract: A mask system including a headgear and cushion module and a seal and frame module provided to the headgear and cushion module. The seal and frame module includes a sealing portion adapted to form a seal with the patient's face and a frame portion adapted to form a breathing chamber. The headgear and cushion module includes a cushion region adapted to support and shape the sealing portion and a headgear region adapted to support and stabilize the mask system on the patient's face.

Abstract: A nasal patient interface for delivery of a supply of pressurised air or breathable gas to an entrance of a patient's airways includes a cushion member that includes a retaining structure and a seal-forming structure permanently connected to the retaining structure, a frame member attachable to the retaining structure, and a positioning and stabilising structure releasably attachable to the frame member.

Abstract: A headgear assembly includes a strap of a first flexible material with an elongate edge, and a second flexible material folded around and running along the elongate edge. The second flexible material may be an elastic material. The second flexible material may also cover an intersection or joint in the first flexible material such that the first flexible material may be made from two flexible materials layered together or joined end to end.
