Abstract

The Portable Personal Diabetic Management System (PPDMS) is a portable data processing unit that calculates the carbohydrate and nutritional content of meals, calculates the insulin dosage for the meal based on the carbohydrate information, logs the nutritional data that it collects, logs the insulin dosage a user actually takes, logs blood sugar test results, and performs analysis of the collected data.

Claims

1. A method for monitoring and maintaining a diet on a portable device, comprising:

receiving a request to measure a weight of a food;

automatically determining, in response to the request, the weight of the food;

automatically retrieving nutritional values of the food based on nutritional information; and

displaying the nutritional values of the food.

2. The method of claim 1 further comprising:

storing the nutritional values of the food.

3. The method of claim 1 further comprising:

automatically determining a first insulin/carbohydrate ratio.

4. The method of claim 3, wherein the automatically determining a first insulin/carbohydrate ratio comprises:

determining a statistical average of a quantity of blood sugar samples from at least one time period;

summing carbohydrate data from the at least one time period;

summing insulin dosage values from the at least one time period; and

quantifying the insulin/carbohydrate ratio by dividing the insulin dosage values by the carbohydrate data.

5. The method of claim 4 further comprising:

adjusting the insulin/carbohydrate ratio to account for a deviation from the statistical average of the quantity of blood sugar samples from a target blood sugar value.

6. The method of claim 3 further comprising:

automatically determining a first insulin dosage based on the first insulin/carbohydrate ratio and the nutritional values of the food.

7. The method of claim 6 further comprising:

displaying the first insulin dosage.

8. The method of claim 6 further comprising:

storing the first insulin dosage.

9. The method of claim 8 further comprising:

storing a time stamp with the first insulin dosage.

10. The method of claim 3, wherein the automatically determining a first insulin/carbohydrate ratio is based on a carbohydrate sensitivity for a time period.

11. The method of claim 10 further comprising:

storing a start time of the time period.

12. The method of claim 10 further comprising:

storing an end time of the time period.

13. The method of claim 1, wherein the nutritional values of the food include at least one selected from the group consisting of (i) calories;

(ii) fat;

(iii) saturated fat;

(iv) cholesterol;

(v) sodium;

(vi) total carbohydrates;

(vii) dietary fiber;

(viii) sugars; and

(iv) protein.

14. The method of claim 1 further comprising:

receiving a first blood sugar value.

15. The method of claim 14 further comprising:

storing the first blood sugar value.

16. The method of claim 15 further comprising:

storing a first time period with the blood sugar value.

17. The method of claim 14 further comprising:

receiving a second time period.

18. The method of claim 17 further comprising:

receiving a second blood sugar value in association with the second time period.

19. The method of claim 18 further comprising:

storing the second blood sugar value and the second time period.

20. The method of claim 19 further comprising:

determining a second insulin/carbohydrate ratio for the second time period.

21. The method of claim 3 further comprising:

receiving a time period to determine a second insulin/carbohydrate ratio; and

automatically determining a second insulin dosage based on the second insulin/carbohydrate ratio.

22. The method of claim 21 further comprising:

storing the second insulin/carbohydrate ratio, the time period and the second insulin dosage.

23. A method for diabetic management provided on a portable device, comprising:

receiving a request to measure a weight of a food;

automatically determining, in response to the request, the weight of the food;

automatically retrieving nutritional values of the food based on nutritional information and the weight of the food; and

determining an insulin dosage based on the nutritional values of the food.

24. The method of claim 23, wherein determining the insulin dosage comprises determining an insulin/carbohydrate ratio.

25. A system for monitoring and maintaining a diet, the system comprising:

a communication interface module for receiving request to measure a weight of a food;

a weight measurement module for automatically determining, in response to the request, the weight of the food;

a data management module for automatically retrieving nutritional information; and

an insulin determination module for determining a nutritional value of the food based on the nutritional information and the weight of the food.

26. The system of claim 25 further comprising a display module for displaying the nutritional value of the food.

27. The system of claim 25, wherein the database manager stores the nutritional value of the food.

28. The system of claim 25, wherein the insulin determination module automatically determines an insulin/carbohydrate ratio.

29. The system of claim 28, wherein the insulin determination module determines a first insulin/carbohydrate ratio by determining a statistical average of a quantity of blood sugar samples from at least one time period, summing carbohydrate data from the at least one time period, summing insulin dosage values from the at least one time period;

and quantifying the insulin/carbohydrate ratio by dividing the insulin dosage values by the carbohydrate data.

30. The system of claim 29 wherein the insulin determination module automatically determines a first insulin dosage based on the insulin/carbohydrate ratio and the nutritional values of the food.

31. The system of claim 30 wherein the communication interface module receives a blood sugar value.

32. The system of claim 31 wherein the data management module stores the blood sugar value.

33. The system of claim 32 wherein the data management module stores a first time stamp with the blood sugar value.

34. A computer-readable medium encoded with instructions for directing a processor to:

receive a request to measure a weight of a food;

automatically determine, in response to the request, the weight of the food;

automatically retrieve nutritional values of the food based on nutritional information; and

display the nutritional values of the food.

35. A computer-readable medium encoded with instructions for directing a processor to:

receive a request to measure a weight of a food;

automatically determine, in response to the request, the weight of the food;

automatically retrieve nutritional values of the food based on nutritional information and the weight of the food; and

determine an insulin dosage based on the nutritional values.

36. The computer-readable medium encoded with instructions of claim 35 further directs a processor to:

determine an insulin/carbohydrate ratio.
