Insulin pumps:

The insulin pump is a device that holds a reservoir of insulin. The pump is programmed to deliver insulin into the body through thin plastic tubing known as the infusion set
The pump is worn outside the body, in a pouch or on your belt. The infusion set has a fine needle or flexible cannula that is inserted just below the skin (usually on the abdomen) where it stays in place for two to three days
Only short or rapid acting insulin can be used in the pump. Whenever food is eaten, the pump is programmed to deliver a surge of insulin into the body similar to the way the pancreas does in people without diabetes. Between meals, a small and steady rate of insulin is released
