Disclosed is a headgear for an interface, comprising a rear loop, a lower side strap extending from the interface to the rear loop, and a pivotable connection. The pivotable connection is located between the lower side strap and the rear loop, or on the lower side strap. The pivotable connection is configured to allow for lateral movement of the lower side strap.

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.

It is discloses a patient interface comprising a seal forming portion, a pad, and a cushion. The seal forming portion may comprise a base surface and a plurality of fibers fixed to and extending away from said base surface for contacting a patient's skin. The cushion may comprise at least along a portion of the circumference a first structure having an elongate section joined with at least one end section oriented substantially perpendicular or at an angle to the elongate section. A first end A of the elongate section may be connected or connectable to a frame member. The end section may be provided at an opposing second end B of the elongate section. The pad may comprise a resilient foam material layer with the seal forming portion. The pad may be adapted to be connected to the cushion.

A patient interface kit to deliver a flow of air at a positive pressure with respect to ambient air pressure to an entrance to a patients airways including at least the entrance of a patients nares while the patient is sleeping. The patient interface comprising: a nasal cushion having a nasal cushion opening; a mouth cushion having a mouth cushion opening, the mouth cushion including a flexible joint, positioned above the mouth opening, to selectively connect the nasal cushion to the mouth cushion; and a positioning and stabilizing structure to provide a force to hold the nasal and/or mouth seal-forming structures in a therapeutically effective position on a patient's head, the positioning an stabilizing structure including a nasal headgear including upper straps or conduits and a mouth headgear including lower straps, the mouth headgear being selectively connected to the nasal headgear.

A patient interface including a seal-forming structure with a textile membrane that has at least one hole such that the flow of air at a therapeutic pressure is delivered to at least an entrance to the patients nares and/or an entrance to the patients mouth. The seal-forming structure is constructed and arranged to maintain the therapeutic pressure in a cavity of a plenum chamber throughout the patients respiratory cycle, in use. The textile membrane includes a first portion that is held in a relaxed state and a second portion that is held in a taut state. The taut state of the second portion is configured to allow the seal-forming structure to include a three-dimensional shape that has multiple curvatures.

The present technology relates to a patient interface for delivery of a flow of pressurised air to an entrance of a patient's airways, the patient interface comprising a mask with a seal-forming structure and one or more positioning and stabilising structures configured to provide a force to hold the mask in a therapeutically effective position on a patient's head in use. The mask and one or more of the positioning and stabilising structures includes a connection port to receive an end of the air circuit. The pressurised air is delivered from the air circuit to the seal-forming structure. In use, the patient connects the air circuit to the connection port of choice, depending on whether they prefer the patient interface to be arranged such that the end of the air circuit is superior to the patient's otobasion superior or inferior to the patient's otobasion superior.

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.

An air conduit for a respiratory therapy device comprises a first end, a second end, and a tube portion, wherein the tube portion comprises a tube wall and an auxiliary structure, such as a rib. The air conduit may deliver a flow of air from a respiratory therapy device or a humidifier to a patient interface. The air conduit may comprise a plurality of auxiliary structures, some of which may consist of a polymeric material, and some of which may comprise a polymeric material and an electrical conductor. An auxiliary structure may be a helical rib extending across a length of the tube portion.

A nasal assembly for delivering breathable gas to a patient includes a frame having an integrally formed first connector portion. A nozzle assembly includes a gusset or base portion and a pair of nozzles. At least one inlet conduit is structured to deliver breathable gas into the frame and nozzle assembly for breathing by the patient. A pair of second connector portions are removably and rotatably connected to respective first connector portions of the frame and are in communication with respective inlet conduits, e.g., directly or via angle connectors. A headgear assembly is removably connected to the pair of second connector portions and/or the angle connectors so as to maintain the frame and the nozzle assembly in a desired adjusted position on the patient's face.

A method of selecting or generating a design for a component of a patient interface device, the method including receiving a scan of at least a portion of a patient's face, receiving preference information about the patient, and generating a custom design or selecting a preexisting design for the component of the patient interface device based on the scan of at least a portion of the patient's face and the preference information, wherein a size or shape of the generated custom design for the component or selected preexisting design for the component is based on the preference information.
