Parker Flex-Tip® tube

FEATURES

This endotracheal tube has a flexible, curved and tapered tip which is meant to facilitate atraumatic intubation. The distal tip, which is the distinguishing feature of this endotracheal tube, is designed to slide past protruding features of the airway, such as the vocal cords and nasal turbinates, without getting hung up on them, causing trauma.

Other design features of this ET tube are a downward facing bevelled opening at the tip and a Murphy eye on each side.


The device is available in a large number of variations, cuffed vs. uncuffed, oral vs. nasal preformed versions, and in a range of sizes suitable for adult and pediatric patients. A reinforced version is also offered.


USES

The device is designed to reduce the risk of traumatic intubation, which is more likely to occur in (mainly) two situations:

1. Nasal intubation, particularly with a narrow passage, e.g. due to relatively large turbinates

2. Oral intubation with a Seldinger technique, i.e. over an introducer device such as a gum-elastic bougie, a fiberoptic bronchoscope, an Aintree intubation catheter, etc., where a gap or sudden 'step-up' exists between the introducer device and the ET tube's outer diameter. This increase in diameter can lead to the ET tube getting 'caught', most likely at the level of the laryngeal inlet or vocal chords. Attempts to advance the ET tube over the introducer device can then be either unsuccessful or cause trauma.
