Insulin Pump Therapy


Insulin pump therapy can give you the better control you want for your lifestyle.

What Is Insulin Pump Therapy?

An insulin pump is a small device about the size of a small cell phone that is worn externally and can be discreetly clipped to your belt, slipped into a pocket, or hidden under your clothes. It delivers precise doses of rapid-acting insulin to closely match your body’s needs:

  • Basal Rate: Small amounts of insulin delivered continuously (24/7) for normal functions of the body (not including food). The programmed rate is determined by your healthcare professional.
  • Bolus Dose: Additional insulin you can deliver “on demand” to match the food you are going to eat or to correct a high blood sugar. Insulin pumps have bolus calculators that help you calculate your bolus amount based on settings that are determined by your healthcare professional.


How does the insulin get into your body?

  1. Insulin pump
  2. Flexible tubing delivers insulin from the pump reservoir to the infusion set
  3. A tiny tube called a cannula is inserted under your skin to deliver insulin
  4. Insulin in the blood

Components of Insulin Pump Therapy

  1. Insulin Pump

A small durable medical device that has:

  • Buttons to program your insulin
  • LCD screen to show what you are programming
  • Battery compartment to hold 1 alkaline battery
  • Reservoir compartment that holds insulin
  1. Reservoir

A plastic cartridge that holds the insulin that is locked into the insulin pump. It comes with a transfer guard (blue piece at the top that is removed before inserting the reservoir into the pump) that assists with pulling the insulin from a vial into the reservoir. A reservoir can hold up to 300 units of insulin and is changed every two to three days.

  1. Infusion Set

An infusion set includes a thin tube that goes from the reservoir to the infusion site on your body. The cannula is inserted with a small needle that is removed after it is in place. It goes into sites (areas) on your body similar to where you give insulin injections. The infusion set is changed every two to three days.

  1. Infusion Set Insertion Device

An infusion set is placed into the insertion device and with a push of a button the infusion set is inserted quickly and easily.

Benefits of Insulin Pump Therapy

Insulin pump therapy provides more flexibility for your lifestyle while giving you greater control of your diabetes1.

Since the insulin pump uses only more predictable rapid-acting insulin, you will not need to follow a strict schedule for eating, activity, and insulin injections. You can eat when you are hungry, delay a meal if you want, even broaden your food choices. If you do activities that lower your blood sugar such as riding your bike, playing with your kids, or gardening, you can reduce your basal rate so that your blood sugar does not drop too low. If you are sick or have an infection and tend to have an increase in your blood sugar, you can increase your basal rate so that your blood sugar does not go up too high. You can also change your meal bolus based on the foods you choose to eat.


  • Better flexibility
  • Fewer Injections
  • Tighter control
  • Fewere long term complications

Better predictability
