ABSTRACT:
A tracheostomy tube, shaped to conform to the trachea, and including an inner and an outer cannula. The extremities of the cannulae inserted in the trachea are in frictional contact to prevent significant gas flow through the annular space between the cannulae. The opposite extremity of the outer cannula is shaped for connection to a respirator with the corresponding end of the inner cannula attached to an adaptive member through a nutating connection. The adaptive member is shaped at its inner end for connection to the outer cannula and at its outer end to a respirator. The outer cannula may include an inflatable cuff for sealing the cannulae within the trachea and a flexible neck flange for limiting the motion of the tracheostomy tube.
