An infusion set is a device that works in conjunction with an insulin pump to administer insulin under the skin. It performs a similar function to an intravenous line, except that the insulin is delivered under the skin. In addition to insulin delivery, the set also helps the patient monitor his or her blood glucose levels.

Some infusion sets use one-touch spring-loaded insertion devices, while others require a manual insertion. Which one you use depends on your personal preference and level of skin sensitivity. Some people may find the manual method more comfortable or faster. However, if you are prone to skin irritation, you may want to choose an infusion set with a built-in adhesive.

Despite the fact that glucose meters and infusion sets share similar functions, their failure rates are very different. While glucose meters are designed to detect blood glucose levels, infusion sets are more directly related to health outcomes. Therefore, if your insulin infusion set fails to deliver insulin, you may need to change it.

Most diabetes patients who use insulin pumps choose flexible cannulas. These are more comfortable to wear, and they don't irritate the skin like fixed cannulas do. Moreover, they are also more convenient for active adults. Flexible cannulas also don't tug the skin the way fixed cannulas do. Most manufacturers also provide a wide range of lengths of tubing to fit your pump and infusion set. You should choose the appropriate length for your needs.
