Abstract
The present invention provides a tracheal tube comprising: a hollow tube inserted into the trachea; a first volume expansion portion for encompassing one side of the hollow tube; a second volume expansion portion positioned below the first volume expansion portion; a first conduit for expanding the first volume expansion portion and the second volume expansion portion; and a second conduit for supplying media for sealing to a trachea sealing portion positioned between the first volume expansion portion and the second volume expansion portion. The tracheal tube of the present invention can reduce the pressure of two cuffs which are the volume expansion portions, and can effectively improve sealing by supplying media to the trachea sealing portion positioned between the two cuffs. The tracheal tube of the present invention can reduce pulmonary aspiration and can thus considerably prevent ventilator-associated pneumonia (VAP).
