ABSTRACT:
An improved tracheal tube cuff for protection of the lungs against aspiration injury and for improved continuous oxygen administration is presented. The low pressure inflatable cuff of this invention attaches to the endotracheal end of a tube and can be placed within the trachea either transorally or through a tracheostomy. The cuff is approximately a pair of inverted paraboloids precisely located on the tube so that upon inflation or expansion under low pressure, the tube will open against the tracheal wall forming a proximal seal against aspirated substances and will open distally beyond the end of the tube to create a seal to gaseous substances under varying pressures such as, but not exclusively, oxygen.
