Patent ID: 7908152

Claim:
A blood glucose monitoring system, comprising: a blood glucose monitoring device for producing digitally encoded blood glucose level signals representative of a blood glucose level of a user; and a programmable microprocessor-based portable unit, separate from said blood glucose monitoring device, comprising: (a) a user interface including (i) a display for displaying information, (ii) a plurality of switches operable for interactively controlling said programmable microprocessor-based portable unit and for manipulating said information displayed on said display and (iii) a circuit coupled to said plurality of switches for generating signals in response to operation of said switches, (b) one or more digital data storage media tangibly embodying therein program instructions, a program identification code associated with said program instructions and calibration information, wherein said program instructions are executed to signal process (i) signals based upon said digitally encoded blood glucose level signals and (ii) insulin dosage data, (c) a signal interface configured to communicate with said blood glucose monitoring device for directly coupling said digitally encoded blood glucose level signals supplied by said blood glucose monitoring device to said programmable microprocessor-based portable unit, and (d) a signal processor for performing signal processing functions by executing said program instructions.
