An implanted port is a device to put medicine, blood, nutrients, or fluids directly into your blood. The port may be used to draw blood for tests only if another vein, such as in the hand or arm, can't be used. People can have a port for weeks, months, or longer.
A port is usually put under the skin of your chest below your collarbone. A thin, flexible tube goes from the port into a large vein. This tube also goes under your skin. It's called a catheter.
A port can be made of plastic, stainless steel, or titanium. It's usually about the size of a quarter, but thicker. It has a silicone bubble in the center. This is called a septum.
Before your doctor puts in the port, you will get medicine to make you sleep or feel relaxed. Then the doctor threads the catheter up a vein in your neck or chest to a larger vein. Next, the doctor puts in the port just under your skin. It looks like a small bump.
Fluid goes into the port through a needle. You will feel a slight pain when the needle goes into the port. Some ports have a small reservoir that can be filled with medicine or fluid. The reservoir slowly puts medicine into your bloodstream. A special needle may stay in the port for a short time. This is called a Huber needle.
Procedures can be stressful. This information will help you understand what you can expect. And it will help you safely prepare for your procedure.
