Abstract

A method of administering insulin includes receiving blood glucose measurements of a patient at a data processing device from a glucometer. The blood glucose measurements are separated by a time interval. The method also includes receiving patient information at the data processing device and selecting a subcutaneous insulin treatment from a collection of subcutaneous insulin treatments. The selection is based on the blood glucose measurements and the patient information. The selection includes one or more of a subcutaneous standard program, a subcutaneous program without meal boluses, a meal-by-meat subcutaneous program without carbohydrate counting, a meal-by-meal subcutaneous program with carbohydrate counting, and a subcutaneous program for non-diabetic patients. The method also includes executing, using the data processing device, the selected subcutaneous insulin treatment.

First claim

What is claimed is:

1. A method comprising:
receiving blood glucose measurements of a patient at a data processing device from a glucometer, the blood glucose measurements separated by a time interval;
receiving patient information at the data processing device;
selecting, using the data processing device, a subcutaneous insulin treatment from a collection of subcutaneous insulin treatments based on the blood glucose measurements and the patient information, the selected subcutaneous insulin treatment includes one or more of a subcutaneous standard program, a subcutaneous program without meal boluses, a meal-by-meal subcutaneous program without carbohydrate counting, a meal-by-meal subcutaneous program with carbohydrate counting, and a subcutaneous program for non-diabetic patients, the subcutaneous standard program comprising:
determining a blood glucose type of the received blood glucose measurement using the data processing device; and
determining a correction insulin dose based on the blood glucose type using the data processing device by calculating:
CB x =(BG x −BG Target )/CF;

wherein CB x is the correction dose based on blood glucose type X, BG x is the blood glucose measurement, BG Target is a target blood glucose value of a patient, and CF is a correction factor; and

executing, using the data processing device, the selected subcutaneous insulin treatment.

2. The method of claim 1 , further comprising:
determining a pre-meal correction bolus using the data processing device by calculating:
CB=(BG−BG Target )/CF;

wherein CB is the pre-meal correction bolus, BG is the blood glucose measurement, and BG Target is a target blood glucose of the patient.

3. The method of claim 1 , further comprising:
receiving, at the data processing device, a governing blood glucose value; and
determining, using the data processing device, an adjustment factor based on the received governing blood glucose value.

4. The method of claim 3 , wherein determining the adjustment factor comprises:
determining when the governing blood glucose value is within a threshold range of values; and
setting the adjustment factor to a preconfigured adjustment factor associated with the threshold range of values.

5. The method of claim 3 , wherein determining the adjustment factor comprises:
determining the governing blood glucose value is within one of multiple pre-configured ranges of values; and
setting the adjustment factor to a pre-configured adjustment factor associated with the pre-configured range of values that includes the governing blood glucose value.

6. The method of claim 1 , further comprising determining, using the data processing device, a Carbohydrate-to-Insulin Ratio based on the adjustment factor by calculating:
CIR=(CIR Previous )/AF;
wherein CIR is the Carbohydrate-to-Insulin Ratio, CIR Previous is a previously determined Carbohydrate-to-Insulin Ratio, and AF is the adjustment factor.

7. The method of claim 1 , wherein the blood glucose type is associated with a blood glucose time associated with a time of measuring the blood glucose measurement, the blood glucose type selected from the group consisting of: a pre-breakfast blood glucose measurement, a pre-lunch blood glucose measurement, a pre-dinner blood glucose measurement, a bedtime blood glucose measurement, a midsleep blood glucose measurement and a miscellaneous blood glucose measurement.

8. The method of claim 1 , further comprising:
determining, using the data processing device, if a breakfast blood glucose measurement has been received at the data processing device from the glucometer; and
when the breakfast blood glucose measurement has been received:
selecting, using the data processing device, a governing blood glucose as a lesser one of a previous midsleep blood glucose measurement or the breakfast blood glucose measurement;
determining, using the data processing device, an adjustment factor for adjusting a current day's recommended basal dose based on the selected governing blood glucose measurement;
retrieving, by the data processing device, a previous day's bed time recommended basal dose; and
determining, by the data processing device, the current day's recommended basal dose by multiplying the adjustment factor times the previous day's bed time recommended basal dose, the current day's recommended basal dose corresponding to an insulin dose of long-acting insulin to be administered to the patient at a configurable frequency of one, two, or three times per day.

9. The method of claim 8 , further comprising, when the breakfast blood glucose measurement has not been received:
blocking, using the data processing device, a basal dose recommendation; and
transmitting a warning from the data processing device to a display in communication with the data processing device, the warning indicating the blocked basal dose recommendation.

10. The method of claim 1 , further comprising:
receiving, at the data processing device, a breakfast blood glucose measurement from the glucometer;
selecting, using the data processing device, a governing blood glucose as one of a previous midsleep blood glucose measurement and the received breakfast blood glucose measurement;
determining, using the data processing device, an adjustment factor for adjusting a current day's recommended basal dose based on the selected governing blood glucose measurement;
retrieving, by the data processing device, a previous day's bed time recommended basal dose; and
determining, by the data processing device, the current day's recommended basal dose by multiplying the adjustment factor times the previous day's bed time recommended basal dose, the current day's recommended basal dose corresponding to an insulin dose of long-acting insulin to be administered to the patient at a configurable frequency of one, two, or three times per day;
wherein the governing blood glucose is selected as the previous midsleep blood glucose measurement when the previous midsleep blood glucose measurement is less than the breakfast blood glucose measurement; and
wherein the governing blood glucose is selected as the breakfast blood glucose measurement when the breakfast blood glucose measurement is less than the previous midsleep blood glucose measurement unless the previous midsleep blood glucose measurement was accompanied by a correction insulin dose exceeding three units of insulin, and an elapsed time between the correction insulin dose and the breakfast blood glucose measurement is less than three hours.

11. The method of claim 1 , further comprising, when the determined blood glucose type is one of a breakfast blood glucose measurement, a lunch blood glucose measurement, or a dinner blood glucose measurement:
after a subsequent blood glucose measurement associated with a subsequent blood glucose type is received, determining, using the data processing device, an adjustment factor for adjusting a next day's recommended meal bolus at a time of day associated with the determined blood glucose type based upon the subsequent blood glucose measurement; and
determining, by the data processing device, the next day's recommended meal bolus at the time of day associated with the determined blood glucose type by multiplying the current day's recommended meal bolus associated with the determined blood glucose type times the adjustment factor.

12. The method of claim 1 , wherein the subcutaneous program for non-diabetic patients comprises:
for each blood glucose measurement received by the data processing device from the glucometer that is less than or equal to a threshold value:
determining, using the data processing devic
