<p>A tracheal assembly comprises an endotracheal tube 10 and a tracheal shield 20. The tracheal shield 20 has a stiff rod 21 extending along the endotracheal tube 10, and a stop 22 at its machine end, which limits the extent of insertion of the shield. At its patient end, the shield 20 has a plate 23 or similar shield member that expands when inserted beyond the end of the tube 10, to protect the posterior wall of the trachea during a tracheostomy procedure. The shield member 23 can be rolled up or otherwise contracted for insertion and removal along the tube 10. <IMAGE></p> |
