- listen (port)
A device used to draw blood and give treatments, including intravenous fluids, drugs, or blood transfusions. The port is placed under the skin, usually in the chest. It is attached to a catheter (a thin, flexible tube) that is guided (threaded) into a large vein above the right side of the heart called the superior vena cava. A port may stay in place for many weeks or months. A needle is inserted through the skin into the port to draw blood or give fluids. Also called port-a-cath.
