What Is an Infusion Set?
The infusion set consists of several parts including an insertion device, needle, cannula (tiny plastic tube) and connector. Each pump brand generally offers an insertion device specific for that infusion set. The insertion device, which is spring-loaded, makes it quicker, easier and more comfortable to place the needle directly into the body fat compared to "free sticking." The needle is then removed and the cannula or soft plastic tube remains in place, connected to the tubing and diabetic pump.
Common Types of Infusion Sets
There are a variety of styles to meet individual needs with different tubing length and needle size. The most common types of infusion sets are broken down into two main groups. The first type is an "angled set" which can be inserted at 10-45-degree angle, but is most commonly placed at 30 degrees. The angled set is recommended for the thinner, leaner, more active individual. The second type is the "straight set" which is inserted in a 90-degree angle or straight into the skin which allows for a shorter needle to be used. You and your health care professional can decide which will work better for you.
Benefits of Pump Infusion Sets
There are many benefits to using a pump infusion set. It alleviates the need for multiple daily injections since the infusion set can safely remain in place for 2-3 days or as directed by your physician. You can disconnect an infusion set when needed, keeping the connector in place for short periods of time for activities such as bathing, swimming or intimate time. Insulin adjustments can easily be made based on meals, exercise, travel and time changes without additional injections. Infusion sets can help you achieve more intensive and tighter control to allow for better blood sugar management.
