Diabetes Meter

I spoke with this man in the shop and I've seen him a device that resembles a pager, I ask what it was and he said to a meter for their diabetes, I was wondering if anyone would not know what this conversation? It's probably a pump, and give him his insulin doses. It looks like a pager, an insulin pump (CSII - continuous subcutaneous insulin infusion). Some of these pumps can be connected to a CGMS (system for continuous glucose monitoring), but the sensor in the body only takes a few days before it needs replacing again. And they are very expensive. In the UK they cost about £ 50 each. It is about $ 80 (U.S.) at current exchange rates. It is an insulin glocometer device that connects to the body, the FreeStyle Navigator. This unit will control blood glucose levels every minute automatically.
