Endotrachael tube with suction catheter and system
First Claim
1. A tracheal secretion evacuation tube for removing pooled secretions from a patient'"'"'s trachea area, said evacuation tube comprising:
- a hollow tube having a wall defining a central passage along its longitudinal axis, said tube having a distal end and a proximal end wherein the distal end is inserted into the trachea area;
an inflatable cuff concentrically disposed on said tube proximal said distal end, said cuff having a top end, a bottom end and a cuff volume;
a tapered pocket positioned on said tube to receive descending secretions;
said pocket comprising a cone-like shape defined by at least one wall between said cuff and said tube;
said pocket tapering down into said cuff and only residing over a portion of the tube for facilitating the collection of descending secretions in the pocket at a plurality of angles;
inflation means for facilitating the selective inflation and deflation of said cuff; and
means for guiding a suction catheter along said tube and at least proximal said pocket.

Abstract
An endotracheal tube and suction catheter system having an inflatable cuff with a collection pocket formed in the cuff for collecting pooled secretions and a railing system for controllably guiding a suction catheter along the tube and into the pocket for aspirating pooled secretions. The cuff has an elongated parallelogram-like shape to counter the rocking phenomenon caused by a patient coughing or turning to keep the cuff in contact with the trachea wall so secretions do not leak past the cuff balloon. The railing system allows the suction catheter to be replaced without having to remove the endotracheal tube from the patient.
