28 What is an Infusion Set? Infusion sets consist of tubing that attaches to the insulin reservoir The infusion set carries insulin to the cannula that is inserted in the subcutaneous tissue The cannula is supported with a plastic hub to the adhesive dressing Site Tubing connector Adhesive tape/pad Cannula

29 Types of Infusion Sets Steel vs Teflon cannula Insertion angle 90º or 30º- 45º Variations in tubing length (45, 60, 80, 110cms) Variations in cannula length 90º range from 5.5mm to 10mm (for varying subcutaneous tissue thickness) 30º- 45º available as 13mm or 17mm Packaged as: complete sets combination sets so tubing changed every other time cannula changed infusion sites only Connection to Reservoir-Luer Lock or Paradigm

40 Why choose an insulin pump? Quality of life More flexibility of lifestyle; eat, sleep, work, play when you want Better control of diabetes Less low blood sugar reactions Decreased chance of diabetes complications Better management of picky eaters, shift workers, athletes, and the list goes on Walsh J, Roberts R. Pumping Insulin, 5 th Edition, 2012.

41 Here is What Pumpers Say Allison Type 1 ʻ06, Pumper ʻ09 I've been on the pump for four and a half months now and love it. I would never go back to shots.

42 Amish Parikh, MD, MEd, FRCPC Type 1 '89, Pumper '02 Insulin pump therapy is very safe. Patients on pump therapy have a better quality of life (as compared to multiple daily injections) and have better overall glycemic control (as measured by HbA1c). These are both achieved with less hypoglycemia. Pump therapy can be fine tuned for the unique needs of each and every patient.
