Abstract:
1. A device for determining blood glucose characteristics, comprising: a sensor input configured for receiving a signal from a sensor, the signal being based on a sensed blood glucose value of a user; a memory configured for storing a plurality of measurements of the sensed blood glucose value of the user from the received signal from the sensor; a display configured for presenting a graphical representation of the plurality of measurements of the sensed blood glucose value; and a controller configured for controlling the presentation of the graphical representation on the display, wherein the graphical representation comprises a trend indicator adapted to indicate an approximate value trend in the sensed blood glucose value over a recent series of the plurality of measurements, wherein the trend indicator comprises a plurality of graphical segments, each of the graphical segments being of different graphical style and assigned to a different range of sensed blood glucose values, each segment being configured for indicating a transition from a first range of sensed blood glucose values to a second range of sensed blood glucose values, and wherein the trend indicator further comprises a slope for indicating a rate of change of the transition from the first range of sensed blood glucose values to the second range of sensed blood glucose values, and wherein the controller is further configured to perform a time analysis for determining a measurement time for an early measurement providing a first sensed blood glucose value assigned to the first range of sensed blood glucose values and a later measurement providing a second sensed blood glucose value assigned to the second range of sensed blood glucose values, and wherein the controller is further configured to prevent the graphical representation of the trend indicator on the display if from the time analysis one of the following conditions is concluded: a time interval between the early and the later measurement is shorter than a minimum time interval, and the time interval between the early and the later measurement is longer than a maximum time interval.
