Abstract

Described herein are systems and methods to utilize factual information based on stored blood glucose data to allow greater insight into the management of diabetes of a user.

Claims

1. A method of notifying a user of a high trend in blood glucose values obtained with a diabetes management unit having a microprocessor coupled to a display, memory and user interface, the method comprising:

performing with the microprocessor, a plurality of blood glucose measurements of the user;

storing in the memory, the plurality of blood glucose measurements of the user;

determining, using the microprocessor, whether a most recent blood glucose measurement measured at a given time during a day is above a pre-determined high threshold;

if the determining indicates that the most recent blood glucose measurement is above the pre-determined high threshold, then evaluating with the microprocessor whether the most recent blood glucose measurement is tagged as either being a measurement before a meal or a measurement made during a fasting period;

if the evaluating indicates that the most recent blood glucose measurement is tagged as being either a measurement before a meal or a measurement made during a fasting period, then determining using the microprocessor whether there are two or more blood glucose measurements stored in memory over the previous N number of days that are above the pre-determined high threshold;

if the determining indicates there are two or more blood glucose measurements stored in memory over the previous N number of days that are above the pre-determined high threshold, then determining using the microprocessor whether the two or more blood glucose measurements determined to exceed the pre-determined high threshold were tagged as being either being a measurement before a meal, a measurement made during a fasting period or both before a meal and during a fasting period;

if the determining indicates the two or more blood glucose measurements determined to exceed the predetermined high threshold were tagged as being either being a measurement before a meal, a measurement made during a fasting period, or both during a meal and during a fasting period, then determining using the microprocessor whether the most recent blood glucose measurement and the two or more blood glucose measurements were performed within a time frame of approximately X hours that brackets the given time during each day but over prior days, wherein a difference in time between the most recent blood glucose measurement and an earliest blood glucose measurement taken over prior days is less than X hours; and

upon achievement of the evaluating that the most recent blood glucose measurement and the two or more blood glucose measurements were performed within the time frame of approximately X hours that brackets the given time during each day but over prior days, then annunciating a high trend warning.

2. The method of claim 1, in which the prior N number of days comprises any number from about 2 to about 90.

3. The method of claim 1, in which the prior N number of days comprises any number from about 2 to about 5.

4. The method of claim 1, in which the prior N number of days is 4.

5. The method of claim 1, in which the X hours comprises any number between about 1 and about 7 hours.

6. The method of claim 1, in which the X hours comprises any number from about 1 to about 3 hours.

7. The method of claim 1, in which the predetermined high threshold comprises about 150 mg of glucose per deciliter of blood.

8. The method of claim 1, in which the annunciating comprises annunciating different message formats with generally the same meaning.

9. A diabetes management system comprising:

a glucose test strip; and

a diabetes management unit comprising;

a housing including a test strip port configured to receive the glucose test strip;

a user interface;

a microprocessor coupled to the test strip port to provide data regarding an amount of glucose measured in a user'"'"'s physiological fluid deposited on the test strip, the microprocessor further coupled to a memory, and user interface buttons;

the microprocessor being programmed to;

a) perform a plurality of blood glucose measurements of the user;

b) store the plurality of blood glucose measurements of the user in the memory;

c) determine whether a most recent blood glucose measurement measured at a given time during a day is above a predetermined high threshold;

d) if a determination indicates that the most recent blood glucose measurement is above the predetermined high threshold, then determine whether the most recent blood glucose measurement is tagged as either being a measurement before a meal or a measurement made during a fasting period;

e) if a determination indicates that the most recent blood glucose measurement is tagged as being a measurement before a meal or a measurement made during a fasting period, or both before a meal and during a fasting period, then determine whether there are two or more blood glucose measurements stored in memory over the previous N number of days that are above the predetermined high threshold;

f) if a determination indicates there are two or more blood glucose measurements stored in memory over the previous N number of days that are above the predetermined high threshold, then determine whether the two or more blood glucose measurements determined to exceed the predetermined high threshold were tagged as being either being a measurement before a meal, a measurement made during a fasting period or both before a meal and during a fasting period;

g) if a determination indicates the two or more blood glucose measurements determined to exceed the predetermined high threshold were tagged as being either being a measurement before a meal, a measurement made during a fasting period, or both before a meal and during a fasting period, then determine whether the most recent blood glucose measurement and the two or more blood glucose measurements were performed within a time frame of approximately X hours that brackets the given time during each day but over prior days, wherein a difference in time between the most recent blood glucose reading and an earliest blood glucose reading is less than X hours; and

h) upon a determination that the most recent blood glucose measurement and the two or more blood glucose measurements were performed within the time frame of approximately X hours that brackets is higher than the high threshold, then annunciate a high trend warning.

10. The system of claim 9, in which the prior N number of days comprises any number from about 2 to about 90.

11. The system of claim 9, in which the prior N number of days comprises any number from about 2 to about 5.

12. The system of claim 9, in which the prior N number of days is 4.

13. The method of claim 9, in which the X hours comprises any number between about 1 and about 7 hours.

14. The method of claim 9, in which the X hours comprises any number from about 1 to about 3 hours.

15. The method of claim 9, in which the predetermined high threshold comprises about 150 mg of glucose per deciliter of blood.

16. The system of claim 9, in which the microprocessor is programmed to annunciate different message formats with generally the same meaning.
