Abstract

A catheter for use in simultaneous tracheal oxygenating and aspirating a patient. The catheter includes an elongated flexible tube arrangement adapted to have at least one end portion extended into the tracheal passage of a patient. The tube arrangement has two separate lumens therethrough. One lumen has at least one opening in the one end portion and is adapted to be connected at the other end of the tube arrangement to a source of suction to permit aspiration of material from the patient through the one lumen. The other lumen has at least one opening at the other end and is adapted to be connected at the other end to a source of oxygen to permit simultaneous oxygenating of the patient through the other lumen while the patient is aspirated through the one lumen.

Claims

1. A catheter for use in simultaneously oxygenating and aspirating a patient comprising;

an elongated flexible tube arrangement adapted to have at least one end portion extended into the tracheal/bronchial passage of a patient, the tube arrangement having two separate lumens therethrough, one lumen having an opening through one end portion and a plurality of holes through the side of said one end portion and adapted to be connected at the other end of the tube to a source of suction to permit aspiration of material from the patient through the one lumen, and the other lumen being closed at the one end and having a plurality of holes through the side of its end portion and adapted to be connected at the other end to a source of oxygen to permit the oxygenating of the patient through the other lumen while the patient is aspirated through the one lumen enabling the separated lumens to operate independent of one another, said side holes in the one lumen being separated from said side holes in the other lumen to facilitate independent simultaneous oxygenating and suctioning of the patient, and the tube arrangement having a smooth outer surface along a continuous arc at least along the one end portion adapted to extend into the tracheal/bronchial passage of the patient thus alleviating patient trauma.

2. The invention in accordance with claim 1 wherein the tube arrangement is one integrally formed tube with separate side by side lumens extending through the tube.

3. The invention in accordance with claim 2 wherein the other lumen terminates adjacent the other end in an aperture in the side wall of the tube arrangement, a connector tube having a passageway therethrough extended through the side opening in fixed position and in fluid communication with the other lumen, the other end of the connector tube having an opening therein for attachment to a conventional connector for a source of oxygen or air.

4. The invention in accordance with claim 2 wherein the other end of the tube arrangement having an opening in the end edge thereof in communication with the one lumen, the opening in the edge being dimensioned to receive one end of a conventional connector for a source of suction for aspiration purposes.

5. The invention in accordance with claim 1 wherein the tube arrangement is formed of two separate tubes interconnected for at least a substantial portion of their lengths and formed with the one lumen extending through one of the tubes and the other lumen extending to the other of the tubes in side by side relationship.

6. The invention in accordance with claim 1 wherein an integral one piece connector is attached to the other end of both lumens, the connector having a first passageway therethrough for communication with the one lumen on one end and with a source of suction on the other end and a second separate passageway therethrough for connection with the other lumen in one end and with a source of oxygen on the other end, the connector having means thereon for separate connection to a source of suction and a source of oxygen to provide communication between the source of suction and the source of oxygen and the lumens through the separate passageways.
