2. About insulin pumps

In this section, you will learn:

  • what an insulin pump is
  • what the parts look like
  • what the differences are between pumps with and without tubing
  • where to carry an insulin pump on your body
  • what you need to do on insulin pump therapy
  • what insulin pumps don’t do

An insulin pump is a small battery-powered device. It’s a way to get insulin instead of giving yourself many injections a day (also called multiple daily injection therapy or MDI). An insulin pump:

  • uses only rapid-acting insulin
  • is attached to your body 24 hours a day 7 days a week, with few exceptions
  • stores insulin in a container, such as a reservoir, cartridge, or pod
  • gives insulin through a small flexible tube (cannula) that goes under your skin
  • gives basal insulin — background insulin to keep your blood glucose levels stable — 24 hours a day at a rate that you program
  • gives bolus insulin — insulin you take at meals or to correct blood glucose — when you push buttons​​​
