Patent ID: 7188034

Claim:
A method for continuous monitoring of an analyte concentration in the living body of a human or animal, the method comprising: determining an analyte values y(t n ) correlating with the concentration of the analyte for consecutive points in time t n ; calculating a prediction value y(t n0 +Δt) over a prediction period Δt based on the analyte value y(t n ) using the following equation: y ( t n0 +Δt )= F ( t n0 , t n0−Δn , . . . , t (n0−(m−2)Δn) , t (n0−(m−1)Δn) ); and generating a warning signal if the prediction value y(t n0 +Δt) deviates from a predetermined value by more than a threshold value, wherein function F(t k , t k−Δn , t k−2Δn , . . . , t k−(m−2)Δn , t k−(m−1)Δn ) depends on the analyte values y(t k ), y(t k−Δn ), y(t k−2Δn ), . . . , y(t k−(m−2)Δn ), y(t k−(m−1)Δn ) and the function F is used to approximate the progression of the analyte values y(t n ) at time t n0 in vicinity U of an analyte value y(t n0 ) with a pre-determined accuracy σ, such that σ 2 ≥ ⁢ ∑ t k ∈ U ⁢ [ y ⁡ ( t k ) - F ( t k - Δ ⁢ ⁢ t , t k - Δ ⁢ ⁢ n - Δ ⁢ ⁢ t , t k - 2 ⁢ Δ ⁢ ⁢ n - ⁢ Δ ⁢ ⁢ t , … ⁢ ⁢ t ( k - ( m - 2 ) ⁢ Δ ⁢ ⁢ n ) - Δ ⁢ ⁢ t , t ( k - ( m - 1 ) ⁢ Δ ⁢ ⁢ n ) - Δ ⁢ ⁢ t ) ] 2 whereby n 0 , m, and Δn are integers.
