An insulin pump delivers a small amount of insulin around the clock via a thin flexible tube.
The tube is connected to a cannula, which is inserted just under the skin. The cannula can usually stay in place for 2-3 days so should not need changing at school unless it becomes dislodged or blocked.
When the child eats, or if their blood glucose level is high, they will need to take extra insulin and will do this by pressing a combination of buttons on the pump.
Younger children, those new to a pump or those with learning difficulties may need help with using their pump.
While insulin pumps are fairly robust and many now are showerproof if not waterproof, they are expensive pieces of equipment and need to be looked after. Pumps may need to be removed for contact sports and swimming – visit the section on physical activity for more information.
