    摘要: A patient interface structure for delivery of respiratory therapy to a patient includes a cushion assembly that has an elastomeric piece with a mouth seal portion configured to seal around the patient's mouth and a nasal seal portion configured to seal against at least an underside of the patient's nose. The cushion assembly also has a cushion clip attached to the elastomeric piece and forms at least part of a plenum chamber with the elastomeric piece. The cushion clip is more rigid than the elastomeric piece. A front plate that is more rigid than the elastomeric piece and has a plurality of headgear attachment points is attachable to the cushion clip by way of a snap fit connection. A gas passage extends along a surface of the front plate and includes an inlet opening configured to connect to an air delivery tube or a connector for an air delivery tube.

    摘要: A patient interface structure for delivery of respiratory therapy to a patient includes a front plate configured to conform to the shape of the patient's face; a mouth cushion defining a breathing chamber and provided to the front plate and configured to seal around the patient's mouth; and a nasal cushion configured to seal the patient's nasal airways. The nasal cushion is supported by the mouth cushion, does not contact a bridge of the patient's nose in use, and extends at least partially into the breathing chamber. A patient interface system includes a patient interface structure and a patient interface structure positioning system configured to position, stabilize and secure the patient interface structure in sealing engagement with the patient's face.
