Patient interface systems

A mask system to treat sleep disordered breathing by providing pressurized air to a patient using components dimensioned to be unobtrusive, the mask system comprising:

• a patient interface adapted to receive pressurized air from an air delivery conduit and contemporaneously provide the pressurized air to a nose of the patient and a mouth of the patient, the patient interface including:
• a cushion to contact a face of the patient when the mask system is worn by the patient, the cushion including:
• a mouth cushion portion shaped to seal (i) below the mouth of the patient between a lower lip of the patient and a chin of the patient, and (ii) above the mouth of the patient between an upper lip of the patient and nares of the patient, when the mask system is worn by the patient, the mouth cushion portion defining a mouth aperture shaped to receive the mouth of the patient, and
• a nose cushion portion shaped to seal around the nares of the patient when the mask system is worn by the patient, the nose cushion portion defining a nose aperture shaped to provide the pressurized air to both nares of the patient, a height of the nose aperture measured between the upper lip of the patient and a tip of the nose of the patient being about 5-15 mm, wherein:
• (i) the cushion is shaped to not contact a bridge of the nose of the patient, when the mask system is worn by the patient,
• (ii) the mouth cushion portion and the nose cushion portion are integrally formed from silicone,
• (iii) a total height of the cushion measured between the chin of the patient and the nose of the patient, when the mask system is worn by the patient, is about 60-75 mm,
• (iv) a total width of the cushion measured between ears of the patient, when the mask system is worn by the patient, is about 90-105 mm, and
• (v) a height of the mouth aperture measured between the chin of the patient and the nose of the patient, when the mask system is worn by the patient, is about 25-35 mm measured at a center of the mouth aperture;
• and
• a frame that connects to the cushion at a non-face-contacting portion of the cushion, the frame having greater rigidity than the cushion.

• a nose cushion portion shaped to seal around the nares of the patient without contacting a bridge of the nose of the patient when the mask system is worn by the patient, the nose cushion portion defining a nose aperture shaped to provide the pressurized air to both nares of the patient, a height of the nose aperture measured between the upper lip of the patient and a tip of the nose of the patient being about 5-15 mm, wherein:
• (i) the nose cushion portion includes a sealing wall that is adapted to engage nasal flares of the patient, when the mask system is worn by the patient,
• (ii) an entire perimeter of the nose aperture is defined by an inner edge of the sealing wall of the nose cushion portion, and
• (iii) the cushion includes a cradle wall that separates the nose aperture from the mouth aperture, the cradle wall being shaped to contact a face of the patient between the upper lip of the patient and the nares of the patient;
• and
• a frame that connects to the cushion at a non-face-contacting portion of the cushion, the frame having greater rigidity than the cushion, wherein the cradle wall hangs below a top of the frame and is structured so that the tip of the nose of the patient rests below the top of the frame, when the mask system is worn by the patient and the patient interface is viewed from in front of the patient.
