Patent ID: 7731659

Claim:
A method for predicting a user's future glycemic state using a continuous glucose sensor, the method comprising: measuring a user's glucose concentration with the continuous glucose sensor at intervals over a predetermined time duration, thereby generating a plurality of glucose concentrations as a function of time; deriving a first glucose prediction equation that is a fit to the plurality of glucose concentrations as a function of time, the fit being based on a first mathematical model; deriving a second glucose prediction equation that is a fit to the plurality of glucose concentrations as a function of time, the fit being based on a second mathematical model; calculating a first predicted glucose concentration g 1 (t f ) at a predetermined future time (t f ) using the first glucose prediction equation; calculating a second predicted glucose concentration g 2 (t f ) at the predetermined future time (t f ) using the second glucose prediction equation; calculating an average predicted glucose concentration and a merit index M based on the first and second predicted glucose calculations; wherein the merit index M is calculated using the following algorithms: M=g 2( t f )− g 1( t f )/ g 2( t f ), if g 2( t f )≧ g 1( t f ) M=g 1( t f )− g 2( t f )/ g 1( t f ), if g 2( t f )< g 1( t f ); inputting the plurality of glucose concentrations as a function of time, the average predicted glucose concentration and the merit index into a trained model that outputs a set of glucose concentration probabilities, and predicting the user's future glycemic state based on the set of glucose concentration probabilities, wherein the first mathematical model and the second mathematical model are non-identical to one another.
