Claim 0:
1. A method of monitoring and affecting a blood glucose concentration of a patient, the method comprising:
determining, using a controller, a meal consumption model indicative of a plurality of different blood glucose concentrations of the patient at a plurality of times responsive to ingestion of a meal, wherein the meal comprises a plurality of glycemic components adapted to release glucose in the patient in different amounts at different times;
determining, using the controller, an insulin model indicative of effects on the blood glucose concentration of the patient responsive to insulin infused in the patient;
obtaining one or more observations of the blood glucose concentration of the patient;
computing values for physiological parameters using the controller by relating the meal consumption model and the insulin model with the one or more observations of the blood glucose concentration of the patient, wherein the physiological parameters are specific to the patient and are to model the blood glucose concentration of the patient and comprise a first meal response gain parameter, a second meal response gain parameter, and a plurality of delay parameters; and
infusing insulin to the patient, using an insulin pump responsive to commands generated by the controller based, at least in part, on the physiological parameters, wherein the physiological parameters are used by the controller to generate the commands to control insulin infusion by the insulin pump.
