    摘要： Conduits for use in a respiratory therapy apparatus for delivering breathable gas to a patient are disclosed. In one example the conduit comprises a tubular wall and a helical formation provided to an outer surface of the tubular wall, wherein the conduit has a stretch limit of at least 100%. In another example a first portion of the conduit has a first stretch limit and a second portion of the conduit has a second stretch limit which is greater than the first stretch limit. The first portion is formed integrally with the second portion, and the helical formation is provided to the first and second portions. In another example the stretch limit of the conduit varies substantially continuously between a first end of the conduit and an opposite second end of the conduit. In other examples the diameter of the conduit varies along the length of the conduit.

    摘要： A patient interface assembly includes a flexible cushion with a nares sealing portion configured to sealingly engage the patient's nares and a mouth sealing portion configured to seal around the patient's mouth. A cushion clip is attached to the flexible cushion, forms at least part of a plenum chamber with the flexible cushion, and is more rigid than the flexible cushion. A frame is attached to the cushion clip, is more rigid than the flexible cushion. A superior portion of the frame extends beyond the mouth sealing portion in the superior direction to overlap at least a part of the pair of lateral nares engagement portions of the nares sealing portion. At least a part of the nares sealing portion of the flexible cushion is decoupled from both the cushion clip and the superior portion of the frame that overlaps the nares sealing portion so that the lateral nares engagement portions are movable independently of the frame and the cushion clip.

    摘要： A patient interface structure for delivery of respiratory therapy to a patient includes a cushion assembly having a mouth seal configured to seal around the patient's mouth and a nasal seal configured to seal against at least an underside of the patient's nose. A cushion clip is attached to the cushion assembly and adds rigidity to the cushion assembly, while a frame with a plurality of headgear attachment points is configured to snap onto the cushion clip. In addition, an air inlet passage along a posterior surface of the frame includes a first end that is configured to attach to an air delivery tube and a second end that is configured to sealingly attach to an opening in the chamber that is at least partially formed by the cushion assembly and the cushion clip. The patient interface structure also includes headgear attachable to the headgear attachment points on the frame.
