Adaptive Hypoglycaemia Alert System and Method
First Claim
1. A system for estimating the onset or presence of a hypoglycaemic condition in a living being, the system comprising a memory, a processor, and:
- at least one first sensor element for obtaining ECG signals representative of the living being'"'"'s ECG;
at least one secondary input element for receiving at least one secondary input parameter;
an output generator for generating an alert signal;
the processor being programmed to;
process the ECG signals, the at least one secondary input parameter and at least one reference value stored in the a memory to estimate the onset or presence of the hypoglycaemic condition;
cause the output generator to generate the alert signal in case the hypoglycaemic condition is occurring or approaching;
receive a feedback input indicative of a possible misestimate of the onset or presence of the hypoglycaemic condition, adjust said reference value in response to the feedback input, and store the adjusted reference value in the memory.

Abstract
The onset or presence of a hypoglycaemic condition in a living being is estimated by obtaining ECG signals, which are processed together with secondary input, such as skin impedance, information about a condition of the living being, or blood glucose level, to estimate whether the living being is experiencing or approaching a hypoglycaemic condition. An output alert may be generated. Feedback indicative of a possible misestimate of the onset or presence of the hypoglycaemic condition is received to allow a system incorporating the invention to adapt and personalize to a specific living being. The feedback may influence one or more sensitivity or specificity settings. Settings of the system may be influenced by the location or rate of movement of the living being.

17. A method of generating an alert signal in case of detection of the onset or presence of a hypoglycaemic condition in a living being, comprising:
-
obtaining ECG signals representative of the living being'"'"'s ECG; receiving at least one secondary input parameter; processing the ECG signals, the at least one secondary input parameter and at least one reference value to estimate the onset or presence of the hypoglycaemic condition; generating an alert signal if the onset or presence of the hypoglycaemic condition is estimated; receiving a feedback input indicative of a possible inaccuracy of the estimation of the detecting of the onset or presence of the hypoglycaemic condition; adjusting the at least one reference value in response to the feedback input; and storing the adjusted reference value. - View Dependent Claims (18, 19)
