Patient interface systems
First Claim
1. A mask system for respiratory therapy that involves delivering pressurized air to airways of a patient, the mask system comprising:
- a patient interface adapted to contemporaneously deliver the pressurized air to a mouth of the patient and a nose of the patient while the patient interface is positioned entirely below a nasal bridge of the patient, the patient interface forming a breathing chamber and including;
a mouth cushion adapted to seal around the mouth of the patient and deliver the pressurized air from the breathing chamber formed by the patient interface to the mouth of the patient, when the mask system is worn by the patient;
a nasal cushion adapted to seal around the nares of the patient and deliver the pressurized air from the breathing chamber formed by the patient interface to the nose of the patient through a nose aperture in the nasal cushion, when the mask system is worn by the patient, the nasal cushion having a dual wall construction comprising (i) a sealing wall arranged to contact a face of the patient, and (ii) a supporting wall, wherein an entire perimeter of the nose aperture is defined by an inner edge of the sealing wall; and
a frame that connects to a non-face-contacting portion of the mouth cushion.

Abstract
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.

29. A mask system for respiratory therapy that involves delivering pressurized air to airways of a patient, the mask system comprising:
a patient interface adapted to contemporaneously deliver the pressurized air to a mouth of the patient and a nose of the patient while the patient interface is positioned entirely below a nasal bridge of the patient, the patient interface forming a breathing chamber and including; a mouth cushion adapted to seal around the mouth of the patient and deliver the pressurized air from the breathing chamber formed by the patient interface to the mouth of the patient, when the mask system is worn by the patient; a nasal cushion adapted to seal around the nares of the patient and deliver the pressurized air from the breathing chamber formed by the patient interface to the nose of the patient, when the mask system is worn by the patient, the nasal cushion having a dual wall construction comprising (i) a sealing wall arranged to contact a face of the patient, and (ii) a supporting wall, wherein the nasal cushion is adapted to deliver the pressurized air to the nose through a nose aperture, the nose aperture being defined by an inner edge of the sealing wall, wherein the supporting wall extends into the breathing chamber to an inner edge of the supporting wall, the inner edge of the supporting wall being separated from the inner edge of the sealing wall, wherein the sealing wall extends inward toward the inner edge of the sealing wall from an outer periphery of the nasal cushion a greater distance than the supporting wall extends inward toward the inner edge of the supporting wall from the outer periphery of the nasal cushion, wherein the supporting wall is absent at a bottom portion of the nasal cushion at which the nasal cushion is adapted to seal with a portion of a face of the patient that is between the upper lip of the patient and the nose of the patient when the mask system is worn by the patient; and a frame that connects to a non-face-contacting portion of the mouth cushion.

-
a patient interface adapted to contemporaneously deliver the pressurized air to a mouth of the patient and a nose of the patient while the patient interface is positioned entirely below a nasal bridge of the patient, the patient interface forming a breathing chamber and including; a mouth cushion adapted to seal around the mouth of the patient and deliver the pressurized air from the breathing chamber formed by the patient interface to the mouth of the patient, when the mask system is worn by the patient; a nasal cushion adapted to seal around the nares of the patient and deliver the pressurized air from the breathing chamber formed by the patient interface to the nose of the patient through a nose aperture in the nasal cushion, when the mask system is worn by the patient, the nasal cushion having a dual wall construction comprising (i) a sealing wall arranged to contact a face of the patient, and (ii) a supporting wall, wherein an entire perimeter of the nose aperture is defined by an inner edge of the sealing wall, wherein the supporting wall is thicker than the sealing wall, wherein the supporting wall extends into the breathing chamber to an inner edge of the supporting wall, the inner edge of the supporting wall being separated from the inner edge of the sealing wall, wherein the sealing wall extends inward toward the inner edge of the sealing wall from an outer periphery of the nasal cushion a greater distance than the supporting wall extends inward toward the inner edge of the supporting wall from the outer periphery of the nasal cushion; a sidewall to which both the sealing wall and the supporting wall connect and from which both the sealing wall and the supporting wall extend into the breathing chamber; and a frame that connects to a non-face-contacting portion of the mouth cushion; and an air delivery conduit arranged to deliver the pressurized air from a flow generator to the breathing chamber, wherein the breathing chamber is adapted to provide the pressurized air to both the mouth of the patient and the nose of the patient.
