FIELD: medical engineering. SUBSTANCE: device is made as thin-walled tube manufactured of flexible biologically neutral material. One end of tube is narrowed, dead and rounded, with at least three holes in its conically narrowed part. Other end of tube is provided with retainer for tube attachment to nostril wall. Retainer is made as a section of larger diameter. This section is coupled to basic part of tube by means of conical section with auxiliary holes over perimeter. External edge of tube is framed with bead. Tube length makes up value equal to at least distance from nostril inlet to middle part of patient's throat. EFFECT: higher efficiency, convenience in operation, improved construction. 2 dwg
