Patent ID: 7853455

Claim:
A blood glucose monitoring system, comprising: a. a blood glucose monitor for monitoring a blood glucose level and for producing digitally encoded blood glucose level signals representative of said blood glucose level; b. a programmable microprocessor-based portable unit that is separate from the blood glucose monitor, said programmable microprocessor-based portable unit including 1) a video display for displaying information, said video display configured to display graphic and multi-line alphanumeric information, 2) a plurality of switches operable for interactively controlling said programmable microprocessor-based portable unit and for manipulating the information displayed on said video display, and 3) a circuit coupled to said plurality of switches for generating video signals in response to the operation of the plurality of switches; c. a digital data storage medium, the medium A. readable by said programmable microprocessor-based portable unit; and B. tangibly embodying therein a program of instructions executable by said programmable microprocessor-based portable unit, said program of instructions including instructions for signal processing in response to signals generated based upon said digitally encoded blood glucose level signals and further for signal processing of insulin dosage data and detecting a need for a change in insulin dosage; d. a signal interface connected in signal communication with said programmable microprocessor-based portable unit and said blood glucose monitor for coupling said digitally encoded blood glucose level signals supplied by said blood glucose monitor to said programmable microprocessor-based portable unit; and e. signal processing means connected in signal communication with said signal interface for performing signal processing functions in accordance with said program of instructions.
