This Flex-Guide Endotracheal Tube Introducer is an economical, critical, nonsurgical adjunct for difficult airway intubation. Its tubing is flexible and can be straightened or bent as required, and it will remain in the desired shape while it is used. Plus, it features an easy to use 60 centimeter length; 1 centimeter bold band to use as highly visible placement depth guide; and a Coude bend (angled end) 2 centimeters from its distal end which vibrates over the tracheal rings as the introducer is moved down the trachea thus confirming to the intubator its correct placement.
