1. A method of determining a diabetic person'"'"'s required amount of insulin (Bolus) 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 variable daily total amount of insulin the person forecasts for a single day; and
calculating the appropriate amount of insulin, based upon the measured blood sugar level, the amount of carbohydrates and sugar ingested by the person and the carbohydrate ratio, being the relation between carbohydrates intake and insulin needed to digest those carbohydrates, and an amount of insulin the person forecasts for a single day, a variable daily total amount of insulin forecasted by the person, by utilizing the following formula;

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.

8. A method of determining a person'"'"'s required amount of insulin (Bolus) to be injected into person in order to achieve person'"'"'s blood sugar level target after ingested food has been digested (or after a chosen period of time) comprising the steps of:
-
determining the person'"'"'s blood sugar level before a meal (BSR);
determining the amount of carbohydrates and sugar ingested by the person during that meal (C);
