Abstract
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.
