Abstract
A cuff assembly for a tracheostomy tube includes an outer bladder and an inner cuff. The inner cuff is positioned adjacent to the tracheostomy tube, and the outer bladder is positioned adjacent to the inner cuff. The outer bladder is made with a less elastic material and operates at a higher relative pressure. The inner cuff is made with a more elastic or hyper-elastic material and operates at a lower relative pressure. A secondary airflow opening is formed on a lateral wall of the tracheostomy tube between the cuff assembly and a main distal opening of the tracheostomy tube.
