ABSTRACT:
A self-contained, presterilized trocar assembly, with an outer cannula and cutting stylet, is just long enough to penetrate the skin of the throat and the cricothyroid membrane and reach the posterior third of the lumen of an average adult trachea. Its short length and self-limiting penetration preclude damage to surrounding tissues. The cannula retains its intratracheal position by a flaring of its distal end after insertion and during a final stage in the deployment. This device enables an unassisted person operating in extreme emergency conditions to establish, quickly and safely, an emergency percutaneous transtracheal airway for a choking person. The tissue damage resulting from the application of the device is minimal, and the incision can be closed with surgical tape.
