Abstract

A method is disclosed for managing a three day profile blood glucose (bG) measurements that are provided by a user using a handheld diabetes management device. The method may involve configuring a database carried by the device to store a plurality of bG test values input by a user for each day of a three day test period. The bG test values are required to be provided by the user in accordance with a predetermined plurality of differing acceptance time windows during each day of the three day test period. If two or more windows are open concurrently when a given bG test value is obtained, the system allows the user to select the appropriate time window that the given bG test value should be associated with. A processing subsystem of the device determines if at least a predetermined minimum plurality of the stored bG test values has been provided by the user during the predetermined plurality of differing acceptance time windows for each day of the three day test period and, if so, the processing subsystem accepts the bG test values provided by the user when compiling results for a three day bG profile.

Claims

configuring a database of the device to store a plurality of bG test values input by a user for each day of a three day test period, wherein bG test values are required to be provided by the user in accordance with a predetermined plurality of differing acceptance time windows during each day of the three day test period;

receiving, by a processing subsystem of the device, a given bG test value at a given time;

recognizing, by the processing subsystem, that at least two of the predetermined plurality of differing acceptance time windows overlap relative to a user set meal time;

prompting, by the processing subsystem, user to select an acceptance time window from the at least two acceptance time windows proximate to the given time when the at least two acceptance time windows are open concurrently;

receiving, by the processing subsystem, a selected acceptance time window from the at least two acceptance time windows, associating the given bG test value with the selected acceptance time window and storing the given bG test value in the selected acceptance time window;

determining, by the processing subsystem, whether a predetermined minimum plurality of the stored bG test values has been provided by the user during the predetermined plurality of differing acceptance time windows for a given day of the three day test period and accepting the bG test values provided by the user as three day bG profile results when the predetermined minimum plurality of the stored bG test values has been provided by the user for the given day; and

discarding the bG test values when the predetermined minimum plurality of bG test values is not provided for the given day of the three day test period.

2. The method of claim 1, further comprising using a display of the device to display the results of the three day bG profile.

3. The method of claim 1, wherein the three day test period during which the bG test values are provided to the processing subsystem requires at least the predetermined minimum plurality of the bG test values to have been provided by the user during the predetermined plurality of differing acceptance time windows during both of first and second successive days that form the three day test period.

4. The method of claim 1, wherein the processing subsystem is configured to restart the three day test period when the predetermined minimum plurality of bG test values is not provided during any one day of the three day test period.

5. The method of claim 1, wherein the processing subsystem removes a collection of the bG test values, from a file of the database, that were obtained during the first and second days of the three day test period, when the predetermined minimum plurality of bG test values is provided during a first day of the three day test period but not during the second day of the three day test period.

6. The method of claim 1, wherein the predetermined plurality of differing time acceptance windows comprises seven different acceptance time windows each having a predetermined duration.

7. The method of claim 6, wherein the seven different acceptance time windows comprise:

a pre-breakfast meal acceptance time window with a user selected breakfast time input to the processing subsystem by the user;

a post-breakfast meal acceptance time window;

a pre-lunch meal acceptance time window;

with a user selected lunch time input to the processing subsystem by the user;

a post-lunch meal acceptance time window;

a pre-dinner meal acceptance time window with a user selected dinner time input to the processing subsystem by the user;

a post-dinner meal time acceptance window; and

a bedtime meal acceptance time window with a user selected bedtime input to the processing subsystem.

8. The method of claim 1, wherein the processing subsystem is used to cause the device to generate one of a tactile land audible reminder, at each one of the predetermined plurality of differing acceptance time windows, to alert the user to conduct a bG test in accordance with a specific one of the acceptance time windows.

9. The method of claim 1, wherein the processing subsystem only considers postprandial labeled bG test values that meet a user preset snack threshold level indicating that a particular bG test value was obtained subsequent to a meal and not subsequent to a snack.

10. The method of claim 1, wherein the display is implemented as a touchscreen display, and wherein the selection choices comprise choices that are presented on the touchscreen for selection by the user.

11. A non-transitory, computer readable medium adapted to run on a processing subsystem of a handheld diabetes management device for managing three day profile blood glucose (bG) measurements input by a user to the device, the computer readable medium comprising:

a database that stores a plurality of bG test values input to the device by a user for each day of a three day test period, wherein bG test values are required to be provided by the user in accordance with a predetermined plurality of differing acceptance time windows during each day of the three day test period; and

the computer readable medium adapted to determine whether a predetermined minimum plurality of the stored bG test values has been accepted during the predetermined plurality of differing acceptance time windows for each day of the three day test period and using the accepted bG test values as test results for a three day bG profile when the predetermined minimum plurality of the stored bG test values has been accepted during the predetermined plurality of differing acceptance time windows for each day of the three day test period; and

the computer readable medium adapted to determine whether the first two days of the three day test period each have the minimum plurality of the stored bG test values obtained therefore and that the third day does not, and clear the previously accepted bG test values obtained during the third day from the database when the first two days of the three day period each have the minimum plurality of the stored bG test values obtained therefore and that the third day does not; and

enabling the test to continue on a successive fourth day following the third day in an attempt to successfully complete the three day test period when the first two days of the three day test period each have the minimum plurality of the stored bG test values obtained therefore and the third day does not, and using the accepted bG test values obtained during the first, second and fourth days to form the three day bG profile results.

12. The non-transitory, computer readable medium of claim 11, wherein the test results are sent to a display of the device for the display to the user.

13. The non-transitory, computer readable medium of claim 11, wherein the non-transitory, computer readable medium is adapted to determine whether the bG test values input to the device by the user have been provided during the predetermined plurality of differing acceptance time windows during both of first and second successive days that form the three day test period.

14. The non-transitory, computer readable medium of claim 11, wherein the predetermined plurality of differing acceptance time windows are implemented in accordance with seven different acceptance time windows over a twenty four hour period, with each one of said seven different acceptance time windows having a predetermined time duration.

15. The non-transitory, computer readable medium of claim 11, wherein the non-transitory, computer readable medium uses the processing subsystem to analyze a marker for each of the bG test values that is provided by the user, and further allows only specific ones of those bG test values to be used for the three day profile that:

have been marked by the user as corresponding to a meal; and

that have been input by the user during ones of the predetermined plurality of differing acceptance time windows.

16. A system for managing three day profile blood glucose (bG) measurements provided by a user, the system comprising:

a handheld diabetes management device, the device including;

a database for storing bG values input to the device by a user for each day of a three day test period;

a processing subsystem in communication with the database, the processing subsystem configured;

to generate a plurality of acceptance time windows for a twenty four hour period;

to analyze the bG test values stored in the database during each twenty four hour period for each day of a three day test period;

to determine whether each of other stored bG test values corresponds to a meal;

to accept only ones of the bG test values input by the user that correspond to a meal, and that have been input during specific ones of the plurality of acceptance time windows over the three day time span;

to allow the user to continue performing the test on a fourth day when the first and second days of the test result in a sufficient number of bG test values being accepted but the third day has an insufficient number of accepted bG test values, in an effort to successfully complete the test;

to clear the previously accepted bG test values obtained during the third day from the database when the first and second days of the test result in a sufficient number of bG test values being accepted but the third day has an insufficient number of accepted bG test values;
