ABSTRACT:
An endotracheal tube assembly which includes a curved section of flexible tubing suitable for insertion into the trachea and having a junction fitting at its outer end extending outside of the mouth of the patient, the junction fitting providing a male connection having an interference fit with the tubing so that the tubing is stretched and enlarged in the region of overlap. The assembly is distinguished by bite block in the form of a ferrule of relatively soft resilient plastic having an inner diameter greater than the diameter of the tubing while providing a snug frictional fit with the tubing concentrated at its outer end in the region of overlap. The bite block has substantially parallel top and bottom surfaces for safe gripping by the teeth of the patient, interconnected by side walls of sufficient thickness as to prevent collapse of the tube upon clenching of the teeth. The bite block is sufficiently long so as to permit adjustment of the degree of insertion of the tube in accordance with radiological observation while keeping the bite block within biting range.
