An endotracheal tube has a PVA open cell foam pack (5) attached to the Endotracheal Tube above the level of the tracheal cuff (3), located 8cm from the distal tip (1). When challenged by any type of fluid at body temperature instantly expands and has a high volume absorption capacity, fully sealing the lower pharynx and delivering a gentle seal that is automatically removed on extubation of the endotracheal tube. |
