Abstract
Abstract A dual function connector for releasable attachment to an endopharyngeal tube, airway intubator or the like. The connector comprises a cylindrical tube having a large diameter proximal portion sized to fit within an airway intubator and a distal portion with a smaller diameter than the proximal portion. Flange means are provided on the proximal portion and extend substantially normal to the longitudinal axis of the connector; and an elongated slot in the connector extends from the distal end throughout the length of the distal portion and into the proximal portion.
