Abstract
A multilumen tracheal tube or catheter is disclosed. The tube has a plurality of ingress and egress lumens, each having a suction or discharge port as appropriate. At least one rotatable collar is provided. The collar overlaps each port and is capable of selecting various combinations of suction and discharge ports without increasing the likelihood of cross contaminating any others.
Claims18
A tracheal tube comprising:
- a cannula having a distal end and a proximal end;
- an inflatable cuff;
- at least one ingression lumen within the cannula having a suction port, the suction port located above the inflatable cuff;
- at least one egression lumen within the cannula in non-communication with the at least one ingression lumen, the at least one egression lumen having a discharge port, the discharge port located above the inflatable cuff on an outside surface of the cannula;
- an inlet for introducing an externally applied therapeutic agent into the at least one ingression lumen;
- and
- an outlet for egress of fluids on the outside surface of the cannula from the at least one egression lumen.

A tracheal tube comprising:
- a cannula having a distal end and a proximal end;
- an inflatable cuff;
- a plurality of ingression lumens within the cannula, each having a suction port located above the inflatable cuff and an inlet located below the inflatable cuff;
- a plurality of egression lumens within the cannula, each having a discharge port located above the inflatable cuff and an outlet located below the inflatable cuff, each ingression lumen is maintained in fluid non-communication with each egression lumen so as to minimize cross-contamination of any ingression lumen with any egression lumen;
- a user manipulable selector for selectively enabling and disabling fluid flow through at least one of an ingression lumen, at least one of an egression lumen, or both.
