Patent ID: 8075527

Claim:
A diabetes management system for treating a patient, comprising: a blood glucose monitor for collecting blood glucose levels in the patient; an insulin pump having a plunger being disposed adjacent a displacement cavity, the displacement cavity having a diaphragm with a wetted surface and a non-wetted surface, the plunger being in contact with the non-wetted surface of the diaphragm; a shape memory alloy wire attached to the plunger to impart reciprocating movement to the plunger; a timing circuit for activating the shape memory alloy wire including an electrical energy storage device for providing electrical energy to the shape memory alloy wire; a reservoir containing a fluid and being in fluid communication with the displacement cavity so that as the shape memory wire imparts movement to the plunger, the diaphragm reacts to the movement of the plunger to expand and thereby pull a predetermined volume of fluid from the reservoir into the cavity; and a remote unit for wirelessly communicating with the blood glucose monitor and the insulin pump.
