Mask System

A modular mask system for delivery of respiratory therapy to a patient, the modular mask system comprising:

• a nares mask portion to seal with a nose of the patient, the nares mask portion defining three apertures including:
• (i) a conduit aperture at which an air delivery conduit is attachable to deliver pressurized air to a nasal breathing chamber formed by the nares mask portion, (ii) a nasal aperture to provide pressurized air from the nasal breathing chamber to the nose of the patient, and (iii) a first connection aperture to provide pressurized air from the nasal breathing chamber to a mouth breathing chamber;
• a mouth mask portion to seal with a mouth of the patient, the mouth mask portion forming the mouth breathing chamber and defining a mouth aperture to provide pressurized air from the mouth breathing chamber to the mouth of the patient, the mouth mask portion removably attachable to the nares mask portion and defining a second connection aperture that fluidly communicates with the first connection aperture of the nares mask portion when the mouth mask portion is releasably attached to the nares mask portion to provide pressurized air from the nasal breathing chamber to the mouth breathing chamber, wherein the modular mask system is adapted to provide respiratory therapy to the patient in both (i) a nares only mode in which the nares mask portion provides said respiratory therapy while detached from the mouth mask portion, and (ii) a nares and mouth mode in which the nares mask portion is releasably attached to the mouth mask portion to provide said respiratory therapy at both the nares and the mouth of the patient;
• and
• headgear structured to maintain the nares mask portion in position on a face of the patient when the nares mask portion is worn by the patient, the headgear including a first upper side headgear portion attachable to the nares mask portion at a first side of the nares mask portion, a second upper side headgear portion attachable to the nares mask portion at a second side of the nares mask portion opposite from the first side of the nares mask portion, an upper headgear portion to extend over a top of the head of the patient, and a rear headgear portion to extend around a back of the head of the portion.

• a mouth mask portion to seal with a mouth of the patient, the mouth mask portion forming the mouth breathing chamber and defining a mouth aperture to provide pressurized air from the mouth breathing chamber to the mouth of the patient, the mouth mask portion removably attachable to the nares mask portion and defining a second connection aperture that fluidly communicates with the first connection aperture of the nares mask portion when the mouth mask portion is releasably attached to the nares mask portion to provide pressurized air from the nasal breathing chamber to the mouth breathing chamber, wherein the modular mask system is adapted to provide respiratory therapy to the patient in both (i) a nares only mode in which the nares mask portion provides said respiratory therapy while detached from the mouth mask portion, and (ii) a nares and mouth mode in which the nares mask portion is releasably attached to the mouth mask portion to provide said respiratory therapy at both the nares and the mouth of the patient, wherein all pressurized air supply connections to supply pressurized air to the nares mask portion and the mouth mask portion are located within the nares mask portion, such that the mouth mask portion is configured to receive pressurized air entirely through the second connection aperture that fluidly communicates with the first connection aperture of the nares mask portion when the mouth mask portion is releasably attached to the nares mask portion, the mouth mask portion including a second flexible membrane to contact the face of the patient entirely around the mouth of the patient and form the seal with the mouth of the patient when the modular mask system is worn by the patient in the nares and mouth mode, the second flexible membrane being separated from the first flexible membrane, wherein the modular mask system is shaped to seal with the face of the patient entirely below a nasal bridge of the patient;
• and
• headgear structured to maintain the nares mask portion in position on a face of the patient when the nares mask portion is worn by the patient, the headgear including a first upper side headgear portion attachable to the nares mask portion at a first side of the nares mask portion such that the first headgear side portion extends between a first eye of the patient and a first ear of the patient on a first side of a head of the patient when the nares mask portion is worn by the patient, a second upper side headgear portion attachable to the nares mask portion at a second side of the nares mask portion opposite from the first side of the nares mask portion such that the second headgear side portion extends between a second eye of the patient and a second ear of the patient on a second side of the head of the patient that is opposite from the first side of the head of the patient when the nares mask portion is worn by the patient, an upper headgear portion to extend over a top of the head of the patient, and a rear headgear portion to extend around a back of the head of the portion.
