First Claim
Patent Images
1. A tracheal tube with a suction lumen comprising:
- a cannula having a length defined by a proximal end and a distal end, the cannula having a respiratory lumen internal to the cannula extending along the length and at least one suction lumen internal to the cannula extending along the length and disposed adjacent to an exterior wall of the cannula;
an inflatable cuff having a shape to block a trachea beneath a glottis of a patient;
a suction source connected to the proximal end; and
an adapter for inserting partially into the exterior wall of the cannula at a position along the length so as to be in communication with the suction lumen proximal to the inflatable cuff, the adapter comprising a plug and a duct with an inlet and an outlet, the outlet interconnecting the duct with the suction source through the suction lumen, the inlet extending the reach of the suction lumen through the duct, the plug adapted to seal the suction lumen between the adapter and the distal end.

Abstract
An adapter for use on a suction lumen of a catheter is disclosed. The adapter is capable of extending the suction capabilities of the catheter to a point distal to a suction port in the catheter. The adapter is at least partially inserted into the catheter. The adapter contains a plug and a duct. The duct has an inlet and an outlet. The duct effectively extends the reach of a suction source and the plug is adapted to seal the catheter between the adapter and the distal end.
