Insulin pumps
An insulin pump is a small electronic device that delivers insulin into your body. It is an alternative to insulin injections.
Getting an insulin pump
In New Zealand, PHARMAC funds insulin pumps for most people with type 1 diabetes, neonatal diabetes, post pancreatectomy or cystic fibrosis-related diabetes. Talk to your diabetes specialist team to find out more about the funding criteria.
Using an insulin pump
The insulin pump is attached to a narrow plastic tube that is inserted under your skin and taped in place. It is often kept in your pocket or on your belt.
The insulin pump only delivers fast-acting insulin, so you need to wear it day and night.
The insulin pump is typically set up in blocks of time to deliver small amounts of insulin. When you need an insulin dose for food or a high glucose level, you enter information into the pump. Your diabetes specialist team provides education and helps you set up your insulin pump.
Getting help with your insulin pump
If you have any questions about your health or your treatment, contact your diabetes team.
If you are unwell, follow your sick day plan.
If you have a technical difficulty with your insulin pump, call the company who provided it. You may need to use injections for your insulin while the pump problem is worked out.
Advantages and disadvantages of insulin pumps
Advantages |
Disadvantages |
|---|---|
Most people have fewer highs and lows. Blood sugar levels are more often in your target range. |
You need to have your pump attached to you all the time. You can only take it off for small breaks, like when you are swimming or showering. |
You do not have to inject as often. |
The tubing can sometimes get blocked, so you might need to change it at short notice. |
You can adjust your insulin more easily before, during and after exercise. |
You need to take time to learn about your pump, especially when you first get it. |
You have more flexibility in what, when and how much you eat. |
There is always a small risk of infection where the sensor goes under your skin. |
You can be more accurate when you are bringing down high sugar levels. |
You still need to inject insulin sometimes. |
Hybrid closed loop feature
Some insulin pumps have a feature called “hybrid closed loop”. This means that when you buy a continuous glucose monitor (CGM), data is transmitted to the pump to automatically adjust the insulin dose. With this system, you still need to enter information when you eat or have a high glucose level.
Continuous glucose monitoring is funded for some people with diabetes, but not for those with type 2 diabetes. See Continuous glucose monitors for details of funding and types of monitors.
