A patient interface structure includes a cushion configured to sealingly engage the patient’s face and a front that is more rigid than the cushion. The cushion includes a forward opening, a rearward opening that is opposite the forward opening and a continuous sealing surface. The continuous sealing surface has a mouth sealing portion configured to seal around the patient’s mouth and a nasal sealing portion configured to seal around both of the patient’s nasal airways. The front plate includes an air inlet configured to both receive the pressurized respiratory gas and secure headgear to the patient interface structure. In addition, the nasal sealing portion includes at least one aperture that is separate from the rearward opening. Also, the front plate, the mouth sealing portion and the nasal sealing portion together form a common chamber.

A mandibular positioning device for use with headgear for Continuous Positive Airway Pressure (“CPAP”) therapy face masks. The device can be integrated with existing headgear to maintain the position of a user's mandible during sleep while using CPAP therapy in order to prevent displacement of the user's face mask as a result of a posterior shift of the mandible. The device can include a pair of saddles for attaching the device to headgear, as well as a support strap which attaches to each saddle and which has a medial portion disposed underneath the user's chin when worn.

A shroud for a mask system includes a retaining portion structured to retain a frame, a pair of upper headgear connectors each including an elongated arm and a slot at the free end of the arm adapted to receive a headgear strap, and a pair of lower headgear connectors each adapted to attach to a headgear strap. The retaining portion, the upper headgear connectors, and the lower headgear connectors are integrally formed as a one piece structure.

A seal-forming structure for a patient interface may include a patient-contacting surface configured to engage the patient's facial skin to form a seal; a posterior opening formed in the patient-contacting surface, the posterior opening configured to provide the flow of air at said therapeutic pressure to the patient's nares; and a support structure extending from the patient contacting surface to an interior surface of the seal-forming structure, the support structure and the interior surface forming a continuous loop, wherein the patient interface is configured to allow the patient to breath from ambient through their mouth in the absence of a flow of pressurised air through the plenum chamber inlet port, or the patient interface is configured to leave the patient's mouth uncovered.

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.
