US 2009/0260632 A1 · Endotracheal Tube

Abstract

A medical device comprises a tube to be inserted into a patient. The tube has a proximal end and a distal end and provides a first fluid into the patient's body from a fluid source via a lumen. The device includes a suction port on the tube which is configured to remove a second fluid from within the patient's body via a suction lumen. The device includes an inflatable cuff that is coupled to the outer surface of the tube. The cuff is positioned adjacent to the suction port and maintains the suction port a distance away from patient tissue. In an embodiment, the cuff is cylindrical and has an inner surface which extends from the proximal side toward the distal side, wherein the inner surface is tapered such that a diameter of the inner surface with respect to the tube decreases from the proximal side toward the distal side.

A medical device comprising:

a tube configured to be inserted into a patient, the tube having a proximal end and a distal end, the tube configured to provide a first fluid into the patient's body from a fluid source via a lumen;
a suction port configured in an outer surface of the tube, the suction port configured to remove a second fluid from within the patient's body via a suction lumen within the tube;
and
a cylindrical cuff coupled to the outer surface of the tube and positioned adjacent to the suction port, the cuff configured to be selectively inflated to a set diameter with a third fluid via a cuff lumen, the cuff having a proximal side and a distal side, wherein the cuff includes a funnel shape of narrowing diameter from the proximal side to the distal side to direct the second fluid toward the suction port.
