An infusion set is used with an insulin pump as part of intensive insulin therapy. The purpose of an infusion set is to deliver insulin under the skin. It is a complete tubing system to connect an insulin pump to the pump user: it includes a subcutaneous cannula, adhesive mount, quick-disconnect, and a pump cartridge connector.
