Graphical display for physiological patient data
First Claim
1. An electronic device having rendered thereon an intuitive graphical display of physiological patient data, comprising:
- a calibrated bar graph that indicates a measurement range for a monitored physiological characteristic; and
a measurement value pointer that moves along the calibrated bar graph to indicate a current value of the monitored physiological characteristic and a direction of change of the monitored physiological characteristic, the measurement value pointer comprising a marker extending from the calibrated bar graph and rendered such that its position is calibrated according to the scale of the calibrated bar graph, and the measurement value pointer further comprising a rate of change pointer integrated with the marker to indicate the direction of change of the monitored physiological characteristic, the rate of change pointer having a base located at the marker, the rate of change pointer terminating at an apex extending from the base, and the rate of change pointer having a displayed length that corresponds to the magnitude of the rate of change of the monitored physiological characteristic, and wherein the displayed length of the rate of change pointer is variable such that the apex is positioned relative to the scale of the calibrated bar graph to indicate a predicted value of the monitored physiological characteristic.

Abstract
An intuitive graphical display as described herein can be rendered by a host device that obtains physiological patient data (such as blood glucose values) in real time or substantially real time. The graphical display includes a calibrated bar graph having a desired measurement range for the monitored parameter. The graphical display also includes a dynamic measurement value indicator that moves along the bar graph in a manner that tracks the current value of the monitored physiological characteristic. The graphical display may also incorporate easy-to-interpret display elements that allow the user to quickly determine whether the current value of the monitored physiological characteristic is within or outside a normal range, whether the monitored physiological characteristic is rising or falling, and the approximate rate of change of the monitored physiological characteristic.

9. A method for displaying, on an electronic display of a device, an intuitive graphical display of physiological patient data, the method comprising:
-
obtaining, at the device, data corresponding to a monitored physiological characteristic; displaying, on the electronic display, a bar graph having a calibrated scale that indicates a measurement range for the monitored physiological characteristic; and displaying, on the electronic display, a measurement value pointer that indicates a current value of the monitored physiological characteristic on the bar graph, and that indicates a direction of change of the monitored physiological characteristic; wherein the measurement value pointer comprises a marker extending from the bar graph and rendered such that the position of the marker is calibrated according to the calibrated scale of the bar graph, and comprises a rate of change pointer integrated with the marker to indicate the direction of change of the monitored physiological characteristic, the rate of change pointer having a base located at the marker and terminating at an apex extending from the base; wherein the rate of change pointer has a displayed length that corresponds to the magnitude of the rate of change of the monitored physiological characteristic, the displayed length being variable such that the apex is positioned relative to the scale of the bar graph to indicate a predicted value of the monitored physiological characteristic; and wherein the rate of change pointer has a displayed angle, relative to a major longitudinal axis of the bar graph, that also corresponds to the magnitude of the rate of change of the monitored physiological characteristic. - View Dependent Claims (10, 11)
