A hybrid stylet and bougie in one simple to use device
The Universal Stylet Bougie, or USB™, represents a significant advance in the design and development of tracheal introducers (bougies) and stylets.
Traditionally, the design requirements of stylets and bougies have always been considered incompatible. A stylet requires sufficient rigidity to allow the tracheal tube to be manipulated to and maintained at a variety of angles, whereas a bougie needs to be flexible enough to allow positive tracheal ring feedback whilst incorporating specific memory characteristics to allow correct placement.
The unique design of the USB™ incorporates two metal inserts with different and distinct properties either side of a more flexible section. The USB™ can easily be manipulated to a variety of angles when used as a stylet, yet has the flexibility when used as a bougie to provide a significantly enhanced level of tracheal ring feedback.
In addition, the hexagonal shape provides less contact with the inner surface of the tracheal tube, providing particularly easy insertion and removal.
