Insulin Pump

An insulin pump is an insulin-delivering device that's used by some people with diabetes. A small battery-operated device that can be worn on a belt or put in a pocket, it's connected to a narrow plastic tube that's inserted just under the skin and taped in place. People who use the pump program it to deliver insulin continuously throughout the day and to release extra doses of insulin to handle rises in blood sugar (after eating, for example).
