ABSTRACT:
A tracheal tube has a cuff surrounding its exterior for being filled with liquid or air to expand the cuff against a patient's trachea to provide a sealed air passage through the tube into the patient's lungs. The cuff, in its expanded configuration, has a bulbed anterior portion which seals against the trachea, and a narrow, elongated posterior portion extending distally away from the bulb. The cuff configuration allows the cuff to stay in a fixed position in the trachea during use, which reduces trauma and irritation to the patient.
