ABSTRACT:
One end of a tee adaptor connects to the proximal end of an endotracheal tube. The other end of the adaptor connects to one end of an elongate transparent flexible bag. The other end of the bag is attached to a catheter tube at a point remote from the adaptor and remote from the distal end of the catheter tube so the catheter tube is sheathed by the bag. A reed valve is between the distal end of the catheter tube and the adaptor connection to the endotracheal tube. The distal end of the catheter tube can be pushed through the reed valve and through the endotracheal tube into the lung for suctioning. The catheter tube has a lumen in its wall through which irrigation fluid is delivered to the distal end as suctioning occurs.
