Abstract

A multi-purpose tracheal tube for use with high frequency ventilation. The tube is an endotracheal tube including up to three lumens, in addition to the primary lumen, which serve various functions to provide versatility in the treatment of patients. In cuffed tubes one of the lumens is used for inflating the cuff once the tube has been placed in the desired position in the trachea of the patient. Another lumen, referred to as the "insufflation lumen", is used to deliver oxygen or other gases by constant insufflation, intermittent jet ventilation or high frequency ventilation. The third lumen, when incorporated, is employed for monitoring and irrigation. The distal opening of the irrigation or monitoring lumen is located just inside the distal tip of the tube while the insufflation lumen opening is located rearwardly toward the proximal end of the tube relative to the irrigation or monitoring lumen opening.
