  • Patent number: 5143062
    Abstract: The present invention relates to an endotracheal tube used for mechanical ventilation of a hospital patient, the endotracheal tube is useful in evacuating contaminated secretions that pool within the trachea above an inflatable cuff associated with the endotracheal tube. The endotrocheal tube of the present invention comprises a double lumen through which air may be circulated, thus creating an indirect gentle suction through a suction eye communicating with the distal ends of the lumens, and located at a position proximal to the inflation cuff. This gentle indirect suction reduces the risk of damage to the tracheal mucosa, which often occurs when applying direct suction.
