Glucose-measurement systems and methods presenting icons
First Claim
1. A glucose measurement system comprising:
- a) a biosensor having at least one electrode responsive to an electrochemical reaction between a fluid sample and an enzyme disposed on the at least one electrode, so that the electrochemical reaction of the biosensor provides a signal representative of a glucose level of the fluid sample;
b) a storage device holding data including definitions of a plurality of state bands of blood glucose, and a plurality of rate bands of rate of change of blood glucose;
c) a processor connected to the biosensor and the storage device and configured to receive successive signals from the biosensor and automatically determine and store corresponding glucose data values, so that the processor determines a rate of change of blood glucose and a corresponding one of the plurality of rate bands using the stored glucose data values and determines one of the plurality of state bands corresponding to a most recent one of the stored glucose data values; and
d) a display coupled to the processor;
e) the processor being further configured to display a state icon on the display in a color corresponding to the determined one of the plurality of state bands and to display a rate icon on the display in a color and shape corresponding to the determined one of the plurality of rate bands, in which the color of the state icon and the color of the rate icon extends over the entirety of each respective icon, so that the processor does not display any other indication of the determined rate of change or of any of the stored glucose data values and wherein neither the state icon nor the rate icon comprise numbers or graphs.

Abstract
A glucose measurement system includes a display and a biosensor that provides a signal representative of a glucose level of a fluid sample. A processor determines glucose data values and a rate of change of blood glucose using the signal. The processor can determine a state band and a rate band using the values and rate, and display a state icon colored per the state band and a rate icon colored and shaped per the rate band. The processor does not display any other indication of the determined rate of change or of any of the stored glucose data values. The processor can also display a unified icon shaped per the rate of change, with a prevailing color determined using the values. The processor does not display any other indication of the determined rate of change or of any of the stored glucose data values. Corresponding methods are also described.

23. A method of displaying information about status of blood glucose in a patient, the method comprising automatically performing the following steps using a processor:
-
successively receiving a plurality of signals from a biosensor having at least one electrode responsive to an electrochemical reaction between a blood sample and an enzyme disposed on the at least one electrode to provide a signal representative of a glucose level of the blood sample; determining a rate of change of glucose level using the received signals representative of respective glucose levels; determining an indication whether the determined rate of change of glucose level is in a normal range; determining an acuteness and one or more color(s) using the most recent one of the received signals, the determined rate of change, and the determined indication; and presenting an icon on a display corresponding to the determined acuteness and color(s), the perimeter of the icon having an at least partially curved segment and, if the determined rate of change is not in the normal range, an opposed acute segment, so that the icon does not include numerical or graphical data of the rate of change or any of the stored glucose data values.
