Patent ID: 8287454

Claim:
A glucose monitoring system comprising: an in vivo sensor for monitoring a glucose level of a user; a sensor control unit coupled to the sensor to output one or more signals associated with the monitored glucose level of the user; and a receiver/display unit in communication with the sensor control unit and comprising: a receiver to receive the outputted one or more signals from the sensor control unit; an input device to receive an input from the user, wherein the input comprises a drug delivery information, a food intake, and an exercise level; a processor to evaluate the one or more signals from the sensor control unit and the input from the user to produce a result comprising the glucose level in interstitial fluid of the user, the glucose level in blood of the user, a rate of change of the glucose level, an acceleration in the rate of change of the glucose level, a dose of a medication and an insulin sensitivity factor; and a display in communication with the processor, wherein the processor temporarily disables a one or more therapy related functions executable by the user if one or more of the glucose level, the rate of change of the glucose level and the acceleration in the rate of change of the glucose level meets or exceeds a threshold level.
