Abstract

A multilumen tracheal tube or catheter is disclosed. The tube has a plurality of suction lumens, each having a suction port. A rotatable suction port collar is provided. The suction port collar has an inlet and an outlet. The collar overlaps each suction port and is capable of selectively occluding a number of the suction ports while enabling unimpeded passage between a remainder of the ports and the outlet.

Claims

1. A tracheal tube comprising:

a tube having a first wall and a second wall concentric to the first wall, the first wall surrounding and defining a ventilation lumen adjacent a first surface, the first wall being attached at a second surface to a first surface of the second wall at a plurality of partitions, a plurality of suction lumens being defined by the second surface of the first wall, the first surface of the second wall, and surfaces of adjacent partitions, each suction lumen having a suction port formed through a portion of the second wall;

a suction port collar having an inlet and an outlet, the collar surrounding the tube and overlapping the suction ports, the collar being selectively positionable so as to enable fluid communication between the inlet and at least one suction port while occluding any remaining suction port, the outlet adapted to connect to a suction source.

2. The tracheal tube of claim 1 wherein the collar is rotatable about the tube.

3. The tracheal tube of claim 1 comprising any of an inflation lumen and an irrigation lumen.

4. The tracheal tube of claim 1 where the suction lumens are disposed radially about the second surface of the first wall.

5. The tracheal tube of claim 1 comprising a guide coupled to the tube and disposed over each suction port, the guide having openings aligned with each suction port, the suction port collar rotationally attached to the guide.

6. The tracheal tube of claim 1 wherein the collar comprises a cylindrical ring having an inner diameter, an outer diameter, and a tubular conduit affixed substantially normal to a plane tangential to the outer diameter, the inlet being at that end of the conduit coincident with the inner diameter, and the outlet being at the opposite end of the conduit.

7. The tracheal tube of claim 1 wherein the inlet is capable of aligning with only a single suction port at any one point in time.

8. The tracheal tube of claim 1 wherein each suction port provides access to multiple suction lumens.

9. The tracheal tube of claim 1 wherein the collar provides a fluid tight seal between the collar and the tube enabling fluid passage only through the suction port selected.

10. The tracheal tube of claim 1 comprising an inflatable cuff sealed to and surrounding the tube at a distal end adapted to seal the trachea of a patient, each suction lumen comprising an inlet port proximal to the inflatable cuff and terminating at the suction ports distal from the inflatable cuff.

20. The tracheal tube of claim 10 wherein the collar selectively and simultaneously occludes all suction ports.

11. A tracheal tube comprising:

a plurality of suction lumens, each suction lumen comprising a suction port; and

a suction port collar comprising an outlet, the collar overlapping each suction port, a portion of the collar selectively occluding a number of the ports while enabling unimpeded passage between a remainder of the ports and the outlet.

12. The tracheal tube of claim 11 comprising a ventilation lumen, the suction lumens being radially disposed about an outer diameter of the ventilation lumen.

13. The tracheal tube of claim 11 wherein each suction lumen comprises an inlet and an outlet, the outlet corresponding to at least one of the suction ports.

14. The tracheal tube of claim 11 wherein the tube comprises a cannula having coaxially oriented lumens, an inner lumen comprising a ventilation lumen, an outer lumen being further divided by partitions into coaxially oriented lumens spaced about the inner lumen.

15. The tracheal tube of claim ii wherein the tube comprises a cannula with the suction lumens disposed therein, each suction lumen being separated from another by a partition.

16. The tracheal tube of claim 15 wherein at least one suction port is intersected by one of the partitions such that the suction port accesses more than one suction lumen.

17. The tracheal tube of claim 15 wherein an interior surface of the collar is rotationally affixed to an exterior surface of the cannula in a fluid tight manner, the collar having a conduit disposed thereon, the conduit having an inlet disposed upon the interior surface of the collar, an outlet, and forming a fluid path between the inlet and the outlet.

18. The tracheal tube of claim 15 comprising a guide affixed to an exterior surface of the cannula, the guide having openings therein corresponding to the suction ports, wherein an interior surface of the collar is rotationally affixed to an exterior surface of the guide, and rotation of the collar about the guide results in the selective occlusion of some of the ports.

19. The tracheal tube of claim 15 comprising an inflatable cuff sealed to and surrounding the cannula at a distal end adapted to seal the trachea of a patient, each suction lumen comprising an inlet port proximal to the inflatable cuff and terminating at the suction ports distal from the inflatable cuff.
