A Venturi connector for tracheal tubes [PDF]
Anaesthesia, 1985 Summary An attachment for tracheal tubes is described. It functions as a holder for a choice of needles used to conduct a Venturi jet powered from a high‐pressure gas system of the kind used for bronchoscopic ventilation. It is suggested as a potentially useful device for some unusual clinical situations, two of which are illustrated.
