An insulin pump is a device about the size of a cell phone that's worn on the outside of your body. A tube connects the reservoir of insulin to a catheter that's inserted under the skin of your abdomen. A tubeless insulin pump also is available. Insulin pumps are programmed to dispense specific amounts of insulin automatically and when you eat.
