Claims16
A mask system for delivery of respiratory therapy to a patient, the mask system comprising:
- a nares sealing portion configured to form a seal with an underside of the patient's nose and comprising a nasal opening configured to be aligned with one of the patient's nares in use;
- a mouth sealing portion configured to form a seal around the patient's mouth and comprising a mouth opening configured to be aligned with the patient's mouth in use, at least a portion of the nares sealing portion being located superior to the mouth sealing portion;
- and
- an anterior surface with an air inlet opening configured to be coupled to a connector and/or an air delivery conduit, a plenum being bound by the anterior surface, the mouth sealing portion, and the nares sealing portion, the plenum being configured to receive a pressurized gas through the air inlet opening and discharge the pressurized gas through the mouth opening and the nasal opening;
- and
- a stiffening structure that is attached to the anterior surface, the stiffening structure comprising a main body and a plurality of connectors extending laterally outward from the main body,
- wherein the main body of the stiffening structure comprises a central aperture that is sized so that the air inlet opening and a portion of the anterior surface surrounding the air inlet opening remain exposed through the central aperture,
- wherein the main body of the stiffening structure is positioned inferior to an anterior part of the nares sealing portion configured to receive the patient's nose tip, and
- wherein the mouth sealing portion includes a silicone cushion.
