Through the following simple questions and related answers, you can get an understanding of what an insulin pump is and how insulin pump therapy works, helping you keep your glucose levels under control whilst maintaining your lifestyle.
An insulin pump is a small electronic device, about the size of a mobile phone. It can be easily carried on a belt, inside a pocket, or even attached to a bra thus becoming virtually invisible to others and allowing a very discreet therapy.
The pump can help you more closely mimic the way a healthy pancreas functions. The pump, through a Continuous Subcutaneous Insulin Infusion (CSII), replaces the need for frequent injections by delivering precise doses of rapid-acting insulin 24 hours a day to closely match your body's needs.
Insulin pump therapy offers multiple clinical benefits over multiple daily injection therapy such as1,2:
It can help to better manage the need for insulin dose adjustment, particularly for meals and overnight and can thus help to achieve better glucose control.
With its ability to adjust insulin delivery, the MiniMed® 640G insulin pump can also provide the following advantages:
The insulin pump consists of:
All MiniMed® infusion sets and reservoirs are meant to work as a system with the pump by providing an innovative interface designed for a more secure fit than a standard connection. The core part of this system is the MiniMed® Connection which is patented* and on every infusion set.
A small durable electronic device that has:
A plastic cartridge that holds the insulin is locked into the insulin pump. It comes with a transfer guard the blue piece at the top that is removed before inserting the reservoir into the pump. This 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 when you change the infusion set. The MiniMed® reservoirs have been designed to make filling a convenient process.
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 would give insulin injections. The infusion set is changed every two to three days. MiniMed® infusion sets are available with a wide range of features (cannula type, length and inclination) so that you can choose the right infusion set for your comfort and protection.
