摘要：
FIELD: medicine.SUBSTANCE: group of inventions refers to medicine. A respiratory device supporting the patients airway when the patient breathes with the respiratory device comprises a body. The body is configured to enclose at least one outer opening of the patients airway. The body forms a number of fluid passages between at least one outer opening of the patients airway and the ambient atmosphere. A number of the fluid passages provide the first sub-collection of the fluid passages consisting of at least one, but not all of a number of the fluid passages. The device also comprises a collection of at least one inhalation valve arranged in the first sub-collection of the fluid passages. At least one inhalation valve enables a gas flow passing relatively freely from the ambient atmosphere into at least one outer opening of the patients airway inside the first sub-collection of the fluid passages. At least one inhalation valve maintains a significant resistance or closes the gas flow from at least one outer opening of the patients airway into the ambient atmosphere inside the first sub-collection of the fluid passages. Overall resistance to the gas flow inside a number of the fluid passages formed by the body for the gas mixture flowing from the ambient atmosphere into at least one outer opening of the patients airways is small enough so that the patient can breathes in through the body freely. Overall resistance to the gas flow inside a number of the fluid passages formed by the body for the gas mixture flowing from at least one outer opening of the patients airways into the ambient atmosphere is high enough so that a patients exhalation generates pressure in the airway to support the airway during exhalation. The device additionally comprises a collection of at least one expiration valve arranged in the second sub-collection of the fluid passages formed by the body. At least one exhalation valve is configured to pass the gas flow from at least one outer opening of
