Abstract: A full-face cushion comprises a frame and a membrane. The membrane has an aperture into which the wearer's nose is received. The membrane is spaced away from the frame. Respective notches receive the bridge of the wearer's nose. The wearer's nose and lips are received through the aperture into the chamber within the mask body. The seal forming portion thus contacts both the surface of the wearer's nose and a portion of the wearer's face in the region between the bottom lip and the chin, and around the sides and over the bridge of the nose.

The header pan is configured to form at least a portion of a fire-resistant barrier. Methods of forming fire-resistant header assemblies comprise forming a first header pan member to define a first lateral portion of a header pan. A second header pan member is formed to define a second, opposing lateral portion of the header pan. The header pan is configured to extend laterally across a header space between a wall of an adjoining structure and an opposing wall of the adjoining structure and to at least substantially longitudinally occlude the header space when the first and second header pan members jointly form the header pan.

Abstract: A mouth cushion for a mask system includes a side wall, an undercushion extending away from the side wall, and a membrane provided to substantially surround the undercushion and adapted to form a continuous seal around an exterior of a patient's mouth in use. The side wall includes spaced-apart prong support structures that provide annular recesses adapted to support respective nasal prongs, and at least a portion of the undercushion includes a question-mark or sickle-shape configuration when in cross-section.

Abstract: Movable partitions and partition systems include a sheet of interconnected panels configured to fold in an accordion fashion. At least two of the interconnected panels have first and second lateral ends extending between a top edge and a bottom edge of the panels. The lateral ends may comprise generally cylindrical structures having openings comprising gaps between lateral edges of the respective panel and a first major surface of the respective panel. The first lateral end of one panel may be engaged with the second lateral end of another panel of the at least two panels. The lateral edges may be enlarged. The at least two panels can extend to a fully extended state in which they are coplanar. Methods of forming movable partitions and partition systems include forming and interconnecting such panels. Methods of repairing movable partitions and partition systems include disengaging such panels by applying lateral forces therebetween.

Abstract: Movable partition systems includes a movable partition engaged with and movable along a longitudinal track and a lead drive box coupled to the movable partition and engaged with the track. The lead drive box is configured to move along the track and move the movable partition along the track. The lead drive box includes a trolley for disposition within the track, a motor coupled to the lead drive box, and a rotatable drive member coupled to the lead drive box and the motor. The rotatable drive member engages an elongated drive member extending along the track to motivate the lead drive box and the movable partition attached thereto along the track when engaged with the motor and the motor is rotating. An electronics module disposed within the lead drive box is configured for controlling operation of the motor responsive to signals originating from sources carried by the lead drive box.

Abstract: Movable partitions comprise a plurality of interconnected panels, at least one sheet of insulation adjacent the plurality of interconnected panels, and at least one hinge member connecting adjacent panels of the plurality of interconnected panels. The at least one hinge member comprises at least one pointed member that extends therefrom. The pointed member is at least partially inserted into the at least one sheet of insulation, and the at least one sheet of insulation is supported by a surface of the at least one pointed member that has a width that is greater than a thickness of the at least one pointed member.

Abstract: A respiratory mask assembly for delivering breathable gas to a patient includes a mask frame having a first cooperating interlocking structure; a mask cushion provided to the frame; a cushion clip to retain the mask cushion on the mask frame, the cushion clip having a second cooperating interlocking structure and being selectively attachable to and detachable from the mask frame, the first and second cooperating interlocking structures interlocking to secure the cushion clip on the mask frame; and an elbow joint provided to the frame and having a swivel tube adapted to connect to a gas delivery conduit.

Abstract: A mask system for use between a patient and a device to deliver a breathable gas to the patient includes a mouth cushion, a pair of nasal prongs, an elbow, and a headgear assembly. The mouth cushion is structured to sealingly engage around an exterior of a patient's mouth in use, and the pair of nasal prongs are structured to sealingly communicate with nasal passages of a patient's nose in use. The elbow delivers breathable gas to the patient. The headgear assembly maintains the mouth cushion and the nasal prongs in a desired position on the patient's face. The headgear assembly provides a substantially round crown strap that cups the parietal bone and occipital bone of the patient's head in use.

Abstract: A mask system includes a frame, cushion, cushion clip, swivel elbow, headgear and/or headgear clips that are configured for use in a clinical or hospital environment.

Abstract: A flow regulation vent for venting washout gas to atmosphere and for regulating flow from a pressurized gas supply includes a fixed portion adapted to engage a gas supply conduit; a spring force biased movable portion in communication with the pressurized gas supply; and a hinge pivotally connecting the movable portion to the fixed portion. The fixed portion has a gas flow orifice and the movable portion is pivotally movable between 1) a relaxed position, below a specified operating pressure to establish a first gas washout flow area, and 2) a fully pressurized position. At or above the specified operating pressure, the pressurized gas pivots the movable portion adjacent the fixed portion to cover at least a portion of the gas flow orifice and establish a second gas washout flow area. The second gas washout flow area is less than the first gas washout flow area.
