First Claim
Patent Images
1. A tracheal tube comprising:
- a flexible cannula having a length, a distal end, and a proximal end, the cannula comprising a plurality of walls extending substantially along the length dividing the cannula into a plurality of separate lumens including a respiratory lumen, a suction lumen, a rinse lumen, and an inflation lumen;
an inflatable cuff surrounding the cannula proximal to the distal end, the inflatable cuff adapted to seal the trachea of a patient, the inflation lumen in fluid communication with the inflatable cuff; and
a port extending through a side wall of the cannula proximal to the inflatable cuff, the port in fluid communication with the suction lumen, the rinse lumen terminating within the suction lumen proximal to the port.

Abstract
A multilumen tracheal tube and a method of suctioning fluids through the same are disclosed. The tube includes a rinse lumen and a suction lumen, the rinse lumen enables rinsing of fluids within the suction lumen while simultaneously suctioning the fluids and ventilating the patient.

8. A method of suctioning fluids from the subglottic space within an intubated patient comprising:
-
inserting a multilumen catheter into a patient'"'"'s trachea, inflating a cuff so as to sealingly engage the walls of the trachea to minimize the flow of fluids from the subglottic space into the patients lungs;
continuously ventilating the patient through at least one lumen of the multilumen catheter comprising a dedicated respiratory lumen;
suctioning fluids from the subglottic space through at least one other lumen comprising a dedicated suction lumen having a port extending through a side wall of the catheter proximate to the cuff;
rinsing the suction lumen by introducing a rinse liquid into the suction lumen proximate to the port through at least another lumen while suctioning fluids from the subglottic space, the rinse liquid being introduced via a dedicated rinse lumen. - View Dependent Claims (9, 10, 11, 12, 13, 14)

15. A tracheal tube comprising:
-
an inflatable cuff having a shape to block a trachea beneath a glottis of the patient;
a cannula disposed through the inflatable cuff, the cannula comprising a respiratory lumen, a suction lumen, and a rinse lumen, the suction lumen comprising a port for suctioning a subglottic space external to the cannula while simultaneously enabling ventilation through the respiratory lumen, the rinse lumen terminating within the suction lumen proximate to the port. - View Dependent Claims (16)
