An insulin pump is a small device that mimics some of the ways a healthy pancreas works. It delivers continuous and customized doses of rapid-acting insulin 24 hours a day to match your body's needs. The pump provides insulin to your body in two ways:
1. Insulin Pump
An insulin pump is a small, durable electronic device used to program your insulin and display how you are tracking. The device also includes a reservoir compartment.
2. Infusion Set
An infusion set includes a thin cannula that goes from the reservoir to the infusion site on your body. The cannula is inserted into the site, similar to where you would give insulin injections. The infusion set should be changed every two to three days.
A reservoir is a plastic cartridge that holds the insulin and is locked into the insulin pump. A reservoir can hold up to 300 units of insulin and should be changed every two to three days.
You can further improve control by using some additional components:
Insulin pump technology offers numerous clinical benefits over multiple daily injection therapy.
Children and adolescents using MiniMed insulin pumps were four times4 more likely to reach their target A1C. A Medtronic pump and sensor system can also reduce low glucose episodes by up to 84% and lower the risk of long-term complications.5,6
Many people with insulin-dependent diabetes may benefit from an insulin pump but aren't aware of the benefits. In general, you may be able to get better control with an insulin pump if you experience any of the following:
Pump technology is not recommended for people:
