Abstract

A noninvasive blood glucose level measurement system for determining the glucose level of blood, including a processor configured for determining a blood glucose level from a measurement of arterial pressure. Also included is a method of determining a blood glucose level from a measurement of arterial pressure.

Claims

1. A noninvasive blood glucose level measurement system for determining the glucose level of blood, comprising a processor configured for determining a blood glucose level from a measurement of arterial pressure.

2. The system of claim 1, wherein said measurement of arterial pressure includes a measurement of systolic arterial pressure and a measurement of diastolic arterial pressure.

3. The system of claim 2, wherein:

(a) said measurement of systolic arterial pressure is an average of a plurality of systolic arterial pressure readings; and

(b) said measurement of diastolic arterial pressure is an average of a plurality of diastolic arterial pressure readings.

4. The system of claim 2, wherein said blood glucose level is determined such that, said blood glucose level equals Ae^BK,wherein,

(a) A is a constant in the range between 1.77and 2.02;

(b) B is a constant in the range between 0.20and 0.3

(c) e is the natural logarithm; and

(d) K is said measurement of systolic arterial pressure divided by said measurement of diastolic arterial pressure.

5. The system of claim 1, further comprising a display device configured for displaying said blood glucose level.

6. The system of claim 5, wherein said display device is further configured for displaying said measurement of arterial pressure.

7. The system of claim 1, further comprising a blood pressure measurement device configured for providing data for said measurement of arterial pressure.

8. The system of claim 1, wherein a deviation of said blood glucose level from a conventional biochemical glucose measurement of the blood is less than 5%.

9. The system of claim 1, further comprising a remote device and an interface arrangement, said interface arrangement being configured for outputting said blood glucose level to said remote device.

10. The system of claim 9, wherein said remote device is configured to determine at least one of a change of medication and a change of medication dose from said blood glucose level.

11. The system of claim 9, wherein said remote device is configured to determine at least one of a change of medication and a change of medication dose from said blood glucose level and said measurement of arterial pressure.

12. A noninvasive blood glucose level measurement method for determining the glucose level of blood, the method comprising the steps of:

(a) receiving a measurement of arterial pressure; and

(b) determining a blood glucose level from said measurement of arterial pressure.

13. The method of claim 12, wherein said step of receiving is performed by receiving a measurement of systolic arterial pressure and a measurement of diastolic arterial pressure.

14. The method of claim 13, further comprising the steps of:

(a) calculating said measurement of systolic arterial pressure as an average of a plurality of systolic arterial pressure readings; and

(b) calculating said measurement of diastolic arterial pressure as an average of a plurality of diastolic arterial pressure readings.

15. The method of claim 13, wherein said step of determining is performed such that, said blood glucose level equals Ae^BK,wherein:

(a) A is a constant in the range between 1.77and 2.02;

(b) B is a constant in the range between 0.20and 0.32;

(c) e is the natural logarithm; and

(d) K is said measurement of systolic arterial pressure divided by said measurement of diastolic arterial pressure.

16. The method of claim 12, further comprising the step of displaying said blood glucose level.

17. The method of claim 16, further comprising the step of displaying said measurement of arterial pressure.

18. The method of claim 12, further comprising the step of taking a blood pressure reading for providing data for said measurement of arterial pressure.

19. The method of claim 12, wherein a deviation of said blood glucose level from a conventional biochemical glucose measurement of the blood is less than 5%.

20. The method of claim 12, further comprising the step of outputting said blood glucose level to a remote device.

21. The method of claim 20, further comprising the step of determining at least one of a change of medication and a change of medication dose from said blood glucose level.

22. The method of claim 20, further comprising the step of determining at least one of a change of medication and a change of medication dose from said blood glucose level and said measurement of arterial pressure.

23. A computer software product, comprising a computer readable medium in which computer program instructions are stored, which instructions when read by a computer, cause the computer to determine the glucose level of blood by performing the steps of:

(a) receiving a measurement of arterial pressure; and

(b) determining a blood glucose level from said measurement of arterial pressure.

24. The computer software product of claim 23 wherein said step of receiving is performed by receiving a measurement of systolic arterial pressure and a measurement of diastolic arterial pressure.

25. The computer software product of claim 24, further comprising the steps of:

(a) calculating said measurement of systolic arterial pressure as an average of a plurality of systolic arterial pressure readings; and

(b) calculating said measurement of diastolic arterial pressure as an average of a plurality of diastolic arterial pressure readings.

26. The computer software product of claim 24, wherein said step of determining is performed such that, said blood glucose level equals Ae^BKwherein:

(a) A is a constant in the range between 1.77and 2.02;

(b) B is a constant in the range between 0.20and 0.32;

(c) e is the natural logarithm; and
