An insulin pump is attached to you with an infusion set. Depending on the design, an infusion set may have a steel or soft cannula. In case you use a soft infusion set, the cannula is inserted with an introducer needle that is removed immediately after insertion. Depending on the design of the infusion set, the cannula may be placed at a 90° angle or a 20-45° angle to the surface of the skin. An infusion set is generally changed every 2 (steel) to 3 (Teflon) days.

You may insert the infusion set in the abdominal area. Most insulin pump users rotate sites on their abdomen, as this area tends to have the best absorption. Consult with your health care provider to see if other sites are appropriate for you. Modern infusion sets are comfortable and easy to use, and there is a style for virtually every insulin pump user.
