Insulin Pumps

What They Do: Insulin pumps are devices that deliver insulin without the need for manual injections. They can administer both basal insulin and bolus (mealtime) insulin once users program the needed insulin dosing. Some new Medtronic systems can automatically suspend insulin dosing when glucose levels are low. Many pumps also come with built in bolus-calculators, which can reduce the hassle of manual insulin dose calculations. All pumps require the user to wear something directly on their body; and most require tubing, though the Insulet Omnipod pump does not.

What Supplies Do I Need?

In addition to the insulin itself, typical insulin pumps require three main components (all of which are connected to the body):

  • Pump

  • Inserted sub-cutaneous (beneath the skin) cannula – delivers insulin

  • Tubing – delivers insulin from the pump to the cannula

The Insulet OmniPod consists of a patch worn on the skin that administers insulin, plus a “Personal Diabetes Manager” device that the user uses to manage insulin dosing.

Choosing a Pump:

With multiple pumps available, it raises the question: "What pump to choose?" There is NO perfect pump, since all devices have benefits and drawbacks depending on your preferences. The table below summarizes our team's experiences with each of the pumps available in the US; the links will take you to the diaTribe test drive.
