Infusion sets are designed to be inserted at a 90° or 20-45° angle to the surface of the skin.
90° insertion angle sets (MiniMed™ Mio™ Advance, MiniMed™ Mio™, MiniMed™ Quick-Set™ and MiniMed™ Sure-T™) benefits people using an insulin pump
- with poor dexterity
- who prefer arm or hard-to-reach infusion sites
- who have needle phobia
- such as children, who are learning to insert their own sets
Angled insertion infusion sets (MiniMed™ Mio™ 30 and MiniMed™ Silhouette™) benefits people using an insulin pump
- with lean or muscular body types
- who experience lipohypertrophy
- who are at a higher risk of dislodging their sets, including active children and athletes (the angle of insertion and the length of the cannula (longer than 90°) may help reduce the risk of dislodgement)
- who are pregnant (from the end of the second trimester onwards, when abdominal tissue is stretched taut)
- who experience site infections. The clear window in the adhesive tape of an angled set allows patients to see any redness around the cannula, thus potentially reducing the risk of a site infection.
Most patients benefit from shorter cannulas (6 mm for 90° sets, 13 or 17 mm for 20-45° angled infusion sets).
To ensure that the insulin is successfully delivered into the subcutaneous tissues, a longer cannula may be necessary for people using an insulin pump
- with a high BMI
- who require large boluses (≥25 units) for meals
- who need high basal rates (≥2.5 units per hour)
Steel needle instead of plastic soft cannula
Steel needle infusion sets (MiniMed™ Sure-T™) are recommended for people using an insulin pump who
- have reactions to plastic cannulae
- are fit and active
- have a history of bent cannulae
- are pregnant (up to the second trimester)
Steel needles are relatively small. Since insertion is similar to taking an injection, steel needle sets can be appropriate for patients who prefer smaller needles. Steel needle infusion sets are typically very easy for patients to learn to use and insert.
