Abstract

A device and method of providing information to a healthcare provider regarding the dosing of insulin is provided where the data is analyzed to produce a qualified set of points. The applied analysis is performed via parameters that are independent of patient input.

Claims

1. A method of processing medical information in a medical advising device including the steps of:

receiving medical information relating to a dosing regimen by the medical advising device;

filtering the data, in the medical advising device, using pre-determined parameters to provide a pair of pre-event and post-event data points, the filtering providing that the data points are identified independently of patient-input associated with the data points other than the numerical and unit value of the data points and independently of time of day associated with the data points; and

displaying the pair of points by the medical advising device.

2. The method of claim 1, wherein the event is carbohydrate intake.

3. The method of claim 1, wherein the pre-event data point includes a timestamp.

4. The method of claim 1, wherein the pre-event data point includes a blood glucose reading associated therewith.

5. The method of claim 1, wherein the pair of points is determined independently of any external event label associated with either of the pair of points.

6. The method of claim 1, wherein one of the pre-determined parameters is that the pre-event data point is required to be within 30 minutes of a carbohydrate ingestion.

7. The method of claim 1, wherein one of the pre-determined parameters is that the post-event data point is required to be within an hour and twenty minutes of a carbohydrate ingestion.

8. The method of claim 1, wherein the dosing regimen is an insulin dosing regimen.

9. The method of claim 1, wherein each event is required to be associated with one and only one pre-event data point and one and only one post-event data point.

10. The method of claim 1, wherein the filtering step includes considering the relative timing of the data points.

11. The method of claim 1, wherein each of the pre-event and post-event data points are blood glucose values and the filtering provides that the data points are identified without considering any patient created association that links the data point with a particular carbohydrate event.

12. A method of assessing efficacy of a regimen in a medical advising device including the steps of:

receiving medical information relating to an insulin dosing regimen by the medical advising device;

filtering the data in the medical advising device using pre-determined parameters that consider the numerical and unit values of the data but are otherwise patient-input independent to provide qualified pairs of pre-carbohydrate ingestion and post-carbohydrate ingestion data points, the pairs of points being determined independently of any external event label associated with either of the pair of points; and

displaying the pairs of points by the medical advising device.

13. The method of claim 12, wherein each event is required to be associated with one and only one pre-event data point and one and only one post-event data point.

14. The method of claim 12, wherein the filtering step includes the step of identifying pre-event and post-event data points from a set of data points and the qualified pairs of data points are identified independently of patient-input that characterizes the input.

15. A non-transitory computer readable medium containing instructions that when executed by a computer performs steps to process medical information, the steps comprising:

receiving data including time-stamped blood glucose readings;

filtering the data using pre-determined parameters that are patient-input independent to provide pairs of pre-event and post-event blood-glucose data points, the pairs of blood glucose data points being determined independently of any patient generated event label associated with any data points within the medical information and independently of the time-of-day of the data points; and

displaying the pairs of points.

16. The non-transitory computer readable medium of claim 15, wherein each event is required to be associated with one and only one pre-event data point and one and only one post-event data point.

17. The non-transitory computer readable medium of claim 15, wherein the filtering step includes the step of identifying pre-event and post-event data points from a set of data points and the data points are identified independently of patient-input other than the values and units of the data points and independently of time of day associated with the data points.

18. A non-transitory computer readable medium containing instructions that when executed by a computer performs steps to process medical information, the steps comprising:

receiving medical information relating to a dosing regimen;

filtering the medical information into pairs of pre-event and post-event data points, the filtering providing that the data points are identified independently of the time of day associated with the data points;

wherein the filtering utilizes pre-determined parameters that are patient-input independent other than the numerical and unit values of the data points; and

displaying the pairs of points.

19. The non-transitory computer readable medium of claim 18, wherein the filtering includes considering a time associated with the pre-event data point relative to a time associated with an event data point and considering a time associated with the post-event data point relative to the time associated with the event, such considerations being directed to the relative time between the data points and being independent of the time of day indicated by the data points.
