The solution was the OBTURATING INTRODUCER FOR A NASAL ENDOTRACHEAL TUBE.

It then became apparent that if you could secure the airway by the oral route, which all anaesthetists are accustomed to, then the nasal airway could be secured in a safe, controlled manner. Using the introducer and a further length of flexible reinforced airway tubing, the method of retrograde nasal intubation allowed the oral airway to be changed to a nasal airway.

Consequently, the NASAL LARYNGEAL MASK and the INTERCHAGEABLE ORAL/NASAL ENDOTRACHEAL TUBE were developed.
