Endotracheal Tube Exchanger

Invention Summary

The endotracheal tube exchanger, used in conjunction with a fiber optic bronchoscope, allows the physician to directly visualize the internal airway as the old tube is cut and removed, allowing the new endotracheal tube to slide into place quickly and accurately. The disposable device includes a slicing tool and oral stabilizer that securely fastens the fiber optic scope and protects the patient’s mouth during tube exchange.

Market Need

The number of critically ill patients requiring mechanical ventilation continues to increase with the aging of the U.S. population. Endotracheal tubes, lifesaving devices to facilitate mechanical ventilation, may need to be exchanged in patients in cases of tube malfunction or prolonged time on the ventilator. Current devices to facilitate exchanging endotracheal tubes are limited in visual scope and stability of use, and safer, more effective devices are needed to perform this procedure.


  • Direct visualization maintained throughout tube placement
  • Enables easy, stable and quick tube exchange
  • User friendly
  • Disposable
  • Inexpensive to produce
