An implantable insulin pump for diabetics is a step nearer thanks to a
mathematical model that draws inferences from changing blood glucose levels. The
algorithm can be encoded in a computer program that fits inside a 30-kilobyte
memory chip, say its developers at the University of Delaware in Newark. Today鈥檚
external pumps deliver a continuous trickle of insulin, but Frank Doyle and
Robert Parker鈥檚 program predicts the patient鈥檚 need for insulin every five
minutes. 鈥淚f the glucose is going up quickly, the algorithm infers that a meal
has been ingested and the pump can respond quickly,鈥� says Doyle. 鈥淥ther models
do not respond until glucose levels are very high.鈥�
