Patent ID: 8568309

Claim:
A method of controlling a subject's diabetes comprising: determining blood glucose level in a blood sample from the subject using a blood glucose test strip which is contacted with the blood sample and wherein current which is passed through the test strip at a constant voltage maintained across two electrodes is continuously measured, where one of the electrodes is connected to ground and the other electrode, which is the working electrode, is maintained at 220 mv, and wherein a digital representation of the current is sampled and stored at regular intervals over a fixed period of time, following the contact with the blood sample, during which time the current flow first rises then falls as the resistance of the test strip drops then rises and such current flow changes are sensed and the voltage on the working electrode is maintained at 220 mv during said fixed period, and the slope of the digital representation is used in determining the blood glucose level; determining the subject's exertion level based on detection of motion patterns from a 3-axis accelerometer, associated with the subject which, based on the acceleration patterns from the three axes, can distinguish walking from jogging from riding in a car; continuously transmitting the blood glucose level and exertion level to a monitor for analysis over a cellular GPRS link, wherein the combined effect on the subject of the exertion level and the blood glucose level are analyzed to determine whether the monitor recommends one or more of: increase or decrease the exertion level, eat carbohydrates, and administer insulin; and receiving the recommendations from the monitor by the subject over the cellular GPRS link.
