Insulin pump therapy makes use of an external device to deliver insulin continuously from a refillable storage reservoir by means of a cannula placed under the skin. A pump is intended to simulate pancreatic function in that it can be programmed to deliver an adjustable basal rate of insulin throughout the day, with higher infusion rates triggered by the push of a button at meal times or to correct a high blood glucose fluctuation.1,2 Insulin pumps have been mainly used in patients with type 1 diabetes. There are a number of recent technological innovations that support a more sophisticated approach to insulin dosing using insulin pumps.3 In this article we provide an overview of the use of such therapy.
