Abstract

The invention comprises a method for visualising a chronological sequence of measurements, in particular obtained from a continuous glucose monitoring (CGM) process, comprising the step of presenting measured data in polar coordinate graphing system. A device 100 is disclosed that comprises a measuring unit 101, in particular a continuous glucose measuring unit, a communication link 103 for transmitting the measured data, in particular a wireless transmission device with a sending 104 and a receiving part 105, and a display 110, optionally with a computing unit 107 that is designed and programmed to visualise data obtained from the measuring unit according to the previously described method, in particular a mobile phone display, MP3 player display, handheld computer display, laptop computer display, personal computer display or other display device being addressable by the communication link. The method and the device enable both the patient and the physician or HCP to improve their recognition of important and/or periodic events during a chronological sequence of (CGM) measurements.

Claims

1. A method for visualising a chronological sequence of measurements, in particular obtained from a continuous glucose monitoring process, comprising the step of presenting measured data in a polar coordinate graphing system.

2. The method as recited in claim 1, characterised in that time is plotted along the circular axis.

3. The method as recited in claim 2, characterised in that numerical values of the presented measured data, in particular the monitored glucose concentration, is plotted along the radial axis.

4. The method as recited in claim 3, characterised in that critical boundaries, in particular thresholds to hyper- or hypoglycemia, are highlighted graphically.

5. The method as recited in claim 4, characterised in that numerical values of different numerical ranges, in particular values above as opposed to values below a target value, are represented by different colours or grey shades.

6. The method as recited in claim 5, characterised in that first values are plotted in a first polar coordinate graphing system, second values are plotted in a second coordinate system, the second coordinate system being different from the first coordinate system, and these coordinate systems can be displayed simultaneously, in particular that the second coordinate system is laid over the first one.

7. The method as recited in claim 6, characterised in that values above a reference value are plotted in the first coordinate system and values below a reference value are plotted in the second coordinate system.

8. The method as recited in claim 7, characterised in that the difference to a reference value or the modulus of the difference to a reference value respectively are displayed.

9. The method as recited in claim 8, characterised in that a radian of 2π

represents a measurement pattern of 12 hours or 24 hours respectively.

10. The method as recited in claim 9, characterised in that a radian of 2π

represents a fixed period of elapsed time, in particular of the last 12 hours or 24 hours respectively, where V1 data of this fixed period of elapsed time is displayed.

11. The method as recited in claim 10, characterised in that the measured data is interpolated to build a smooth curve.

12. The method as recited in claim 11, characterised in that the area between the origin of the coordinate system and a curve is displayed coloured or grey shaded.

13. The method as recited in claim 12, characterised in that the colour or grey shade shows a transparency so multiple covering of an area in subsequent revolutions leads to gradual darkening of it.

14. A device comprising a measuring unit, in particular a continuous glucose measuring unit, a communication link for transmitting the measured data, in particular a wireless transmission device with a sending and a receiving part, and a display, optionally with a computing unit that is designed and programmed to visualise data obtained from the measuring unit according to claim 13, in particular a mobile phone display, MP3 player display, handheld computer display, laptop computer display, personal computer display or other display device being addressable by the communication link.
