University of Virginia (UVa) researchers working with Virginia-based TypeZero Technologies developed software that automatically monitors blood glucose levels of patients with Type 1 diabetes.

The team suggests the artificial pancreas system could relieve diabetics from the stress of constantly monitoring blood glucose levels and insulin intake.

The system features a continuous glucose monitoring (CGM) sensor, an insulin pump, and a control algorithm; the sensor is implanted under the patient's skin and continuously collects data on blood glucose levels. This data is sent to an external processor housing the control algorithm, which performs calculations to provide dosing instructions for the insulin pump.

UVa's Marc Breton said, "What we do is we make the [CGM and insulin pump] talk to each other. We put a brain in the middle, something that can analyze how much insulin has been administered, how much should be now, and do that every five minutes."
