ABSTRACT:
A system for replacing a tracheal tube uses an obturator that is inserted into the existing tube until it protrudes out from the distal end. The old tube is then slid out using the obturator as a guide. A new tube is inserted along the obturator until it has been properly inserted. The obturator is then removed. The obtuator has a flexible atraumatic tip at one end and a gripping section at the outer end. It is made from a flexible radiopaque material and has positioning marks to facilitate use with both endotracheal and tracheostomy tubes.
