Glucose level control method and system
First Claim
1. A method of self-monitoring a patient'"'"'s blood glucose condition to determine a long-term effect of the patient'"'"'s behavior on his blood glucose level, the method comprising:
- collecting measured data during a predetermined time period while taking a sequence of measurements of the blood glucose level during a day and repeating the sequence of measurements from several days to several weeks, said sequence of measurements including non-invasive-measurements utilizing application of pressure to the patient'"'"'s blood perfused fleshy medium, said application of pressure including application of over-systolic pressure thereby causing a state of temporarily blood flow cessation in the medium, the measured data being in the form of time variations of light responses of the medium to incident light for at least two different wavelenghts of the incident light, respectively;
analyzing the measured data to determine a relation between changes in the two time variations indicative of the glucose concentration in the patient'"'"'s blood, and determine a distribution of average glucose values within said predetermined time period, andpresenting results of the determined distribution of the average glucose values in a visual or auto format to the patient or an authorized person.

Abstract
A method and device are provided for self-monitoring a patient'"'"'s blood glucose condition to determine a long-term effect of the patient'"'"'s behavior on his blood glucose level. A sequence of measurements of the blood glucose level is applied during a day, the sequential measurements are repeated during a predetermined time period from several days to several weeks, and measured data are collected. The measured data is analyzed to determine a distribution of the average glucose values within said predetermined time period, thereby providing a feedback for the patient or an authorized person.
