FIELD: medical engineering.
SUBSTANCE: device has tracheal cannula and dilating tampon rigidly connected into a T-shaped structure. The dilating tampon is 50-60 mm long and has longitudinally arranged angular ribs on the external surface. The tracheal cannula is 20 mm long and has smooth external surface. The tracheal cannula maximum diameter and tracheal cannula maximum diameter are related by proportion of 2:3, the internal diameters coinciding.
EFFECT: enhanced effectiveness in dilating trachea lumen and that of the subfolder larynx part.
