Abstract:
A mask system includes a cushion for a mask that seals at its upper extent in a region of the nose that is generally above the tip of the nose or pronasale, and extends across a portion of the cartilaginous framework, alar or flares of the patient's nose, e.g., not extending over or across the nasal bone of the patient's nose.
Abstract:
A nasal patient interface for delivery of a supply of pressurised air or breathable gas to an entrance of a patient's airways comprising: 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 respiratory mask assembly for delivering breathable gas to a patient includes a frame and at least one locking clip. The frame has a main body and a side frame member provided on each lateral side of the main body, at least one of the side frame members including a locking clip receiver assembly. The at least one locking clip has a main body providing a front portion adapted to be removably coupled with the at least one locking clip receiver assembly and a rear portion adapted to be removably coupled to a headgear assembly. The rear portion includes a cross bar that forms an opening through which a strap of the headgear assembly can pass and be removably coupled with the cross bar, and the front portion includes at least one resiliently flexible spring arm that is flexible within the plane of the main body.
Abstract:
A respiratory mask assembly for delivering breathable gas to a patient includes a frame and a headgear assembly removably attachable to the frame. The headgear assembly includes a pair of side portions and a rear portion that interconnects the pair of side portions. The pair of side portions includes at least one strap. The rear portion has at least one strap constructed of at least two layers of material. One of the layers of material has a more rigid construction than the other of the layers of material to resist compression of the at least one strap of the rear portion in a first direction which resists movement of the at least one strap of the pair of side straps in the first direction.

Abstract:
A vent assembly includes at least one vent having a first end configured to face atmosphere and a second end opposite the first end, and a central portion provided between the first and second ends including a substantially cylindrical cross-sectional shape, wherein the second end includes a counter bore.
Abstract:
A forehead pad for use in a respiratory mask with a forehead support, which includes a base portion to contact a user's forehead, a support post connected to the base portion, and a head adapted to connect the support post to a forehead support. A pair of forehead pads may be joined with a connector.
Abstract:
A respiratory mask assembly including a frame and a cushion provided to the frame. The cushion including a non-face contacting portion removably attached to the frame and a face-contacting portion adapted to engage a patient's face. The face-contacting portion includes a side wall, a rim extending from the side wall and curving inwardly into a cavity of the cushion, and a membrane substantially surrounding the rim and including an inside surface spaced from an outside surface of the rim. The cushion includes a gusset portion extending radially outwardly from the side wall of the face-contacting portion and a reinforcing ring between the gusset portion and the face-contacting portion. The reinforcing ring is constructed and arranged to act as a stiffening hoop to reduce the tendency of the cushion to expand when under pressure.
Abstract:
An adjustable mask system (100) includes a cushion with a seal (130) having the ability to change size and/or shape. The seal is preferably a one-piece, continuous member without interruptions. To effect adjustment of the size and/or shape of the seal, an actuator may be provided, which may take the form of a dial (190).
Abstract:
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.
