FIELD: medicine.
SUBSTANCE: declared group of inventions refers to nasal cannula (26, 26'') for a pillow element adapted for use with a nasal mask of a patient for delivering a respiratory gas flow and a nasal mask of a patient for delivering a respiratory gas flow comprising pillow element (12) comprising nasal cannula (26, 26''). Nasal cannula comprises housing (134, 134'', 136, 136'') and bottom cover (138, 138', 138''). Housing and bottom cover form a cavity. Cavity is filled with a filling substance. Filling substance is a viscoelastic material or an elastic material. Housing is configured to deform and conform to the shape of the nostril portion when the nostril is pressed against the housing. Housing includes outer housing (134, 134''), located on an external portion of nasal cannula (26, 26''); and inner housing (136, 136'') located on the internal portion of nasal cannula (26, 26''). Valve (132, 132', 132'') extends from the body and is configured to insert nostril (50) of the patient into the interior. In outer housing (134, 134'') is formed recess (142, 142'') in form of notch or dent in outer housing, wherein recess (142, 142'') increases perimeter of space formed by outer housing (134, 134''), inner housing (136, 136'') and bottom cover (138, 138''). When the patient's nostril (50) is pressed onto the outer housing, the outer housing corresponds to the patient's nostril shape and forms a seal with the patient's nostrils. Inner housing and/or outer housing of nasal cannula are made of material that can be stretched in tension. Inner housing and outer housing of nasal cannula have different thickness. Thickness of outer housing is maximum at section of outer housing connected with bottom cover, and is minimum at section of outer housing connected with valve. Nasal mask comprises nasal cannula (26, 26'').
EFFECT: tight closure of patient's nostril and around it and provision of optimal comfort for patient.
