Abstract

The invention calculates the precise amount of insulin needed by someone (the user) who is diabetic and/or insulin/insulin-pump user, in order to keep the user'"'"'s blood sugar concentration in the previously set target, and provides a practical method to make the necessary changes (weekly, monthly, every other month, etc) in the personal carbohydrate ratio profile, and more specifically the invention, calculates the user'"'"'s carbohydrate ratio at any given time and allows the user to determine the amount of insulin (Bolus) to be injected.

Claims

1. A method of determining a diabetic person required amount of insulin to be injected into person in order to maintain proper blood sugar levels, comprising the steps of:

determining the person'"'"'s blood sugar level;

determining the amount of carbohydrates and sugar ingested by the person;

determining the amount of insulin the person forecasts for a single day; and

calculating the appropriate amount of insulin, based upon the blood sugar level, the amount of carbohydrates and the forecast of amount of insulin, needed to be injected into the person at that time in order to maintain the appropriate level of blood sugar in that person.

2. The method as claimed in claim 1 wherein the step of determining the person'"'"'s blood sugar level comprises determining the prandial blood sugar level using a glucose concentration measuring system.

3. The method as claimed in claim 1 wherein the step of determining the amount of carbohydrates and sugar ingested by a person further comprises dividing the amount of carbohydrates and sugar ingested by a carbohydrate ratio and interpolating a resultant of the division to determine a carbohydrate ratio as a function of time.

4. The method as claimed in claim 1 wherein the step of calculating the appropriate amount of insulin further comprises the steps of calculating the insulin by the following formula:

Insulin=(C/CR)+(BSR−

BST)/IS

Wherein C=total amount of carbohydrates, CR=carbohydrate ratio, BST=target blood sugar, BSR=blood sugar reading, and IS=insulin sensitivity.

5. An apparatus for determining a diabetic person required amount of insulin to be injected into the person in order to maintain proper blood sugar levels, comprising:

a measuring means for determining the person'"'"'s blood sugar level;

a calculating means for determining the appropriate amount of insulin, based upon a) the measured blood sugar level, b) an amount of carbohydrates and sugar ingested by the person, and c) an amount of insulin the person forecasts for a single day, needed to be injected into the person at that time in order to maintain the appropriate level of blood sugar in that person.

6. The apparatus as claimed in claim 5 wherein the measuring means for determining the person'"'"'s blood sugar level is a glucose concentration measuring system.

7. The apparatus as claimed in claim 5 wherein the calculating means further calculates the insulin by the following formula:

Insulin=(C/CR)+(BSR−

BST)/IS

Wherein C=total amount of carbohydrates, CR=carbohydrate ratio, BST=target blood sugar, BSR=blood sugar reading, and IS=insulin sensitivity.
