Tracheal Catheter With Suction Lumen Port in Close Proximity to the Cuff
First Claim
1. A tracheal catheter comprising:
- a cannula having a respiratory lumen and a suction lumen and an inflatable cuff, the suction lumen terminating in a suction lumen port for proximal to the inflatable cuff to allow suctioning of the subglottic space external to the cannula while simultaneously enabling ventilation through the respiratory lumen;
said inflatable cuff having a proximal part attached to the cannula, overlaying a portion of the suction lumen port.

Abstract
Endotracheal and tracheostomy tubes have an inflatable cuff for sealing the trachea so that a patient may be ventilated through a respiratory lumen of the tube. As a result of sealing the trachea outside of the tube, liquids accumulate above the cuff. If these liquids are allowed to move into the lungs, they may cause ventilator acquired pneumonia (VAP). The liquids may be removed by suction applied to a suction lumen terminating in a port above the cuff, but suctioning can cause damage to the trachea if the tube is sucked up against the tracheal wall. A tracheal catheter having a unique method of attaching the balloon cuff is provided. The cuff is to attached so that an upper part (collar) of the cuff is used to cover the distal end of a suction lumen port. This allows the port to be located closer to the cuff and so provides more thorough liquid removal and reduces the possibility that the tube may suck itself onto the tracheal wall.

8. A method of attaching a cuff to a cannula having a suction lumen port comprising:
-
providing a cannula having a distal end, a proximal end, an inflatable cuff proximate to the distal end for sealing the trachea from the lungs at the subglottic region, and a respiratory lumen; providing a suction lumen terminating in a suction lumen port located proximal to the cuff for suctioning a subglottic space external to the cannula while simultaneously enabling ventilation through the respiratory lumen; attaching a proximal collar of said cuff to said cannula in a manner that overlays a distal portion of said suction lumen port.
