Patent ID: 7904310

Claim:
A system for performing diabetes self-care using at least two devices in communication with one another, comprising: (a) a blood glucose monitoring device, including: (i) a receptacle for receiving an amount of blood sufficient for the blood glucose monitoring device to run a blood glucose test sequence; (ii) processing circuitry for controlling the blood glucose test sequence and computing a blood glucose level, (iii) a power source for powering the blood glucose monitoring device, and (b) a portable microprocessor-based device directly coupled with the blood glucose monitoring device for receiving blood glucose test results directly from said blood glucose monitoring device, including: (i) an interactive interface, including (A) a display screen, and (B) a plurality of switches including a pair of spaced-apart push button switches, (ii) a microprocessor that runs according to program instructions stored in a memory for performing analysis of the blood glucose test results, signal processing of insulin dosage data, and detecting a need for a change in insulin dosage, and (iii) said memory for (A) recording the blood glucose test results and the insulin dosage data therein, (B) containing programming for establishing a data protocol that allows digital data signal processing, (C) performing analysis of blood glucose, and (D) storing time and date tagged glucose test results and calibration information.
