Abstract
Methods of regulating blood glucose levels using an insulin pump are disclosed. A method includes receiving a current blood glucose level, and determining whether the current blood glucose level is above a threshold value. The method also includes calculating a correction bolus value based upon the current blood glucose.
Claims21
A method of regulating blood glucose levels using an insulin pump, the method comprising:
- receiving a current blood glucose level at an insulin pump;
- determining whether the current blood glucose level is above a threshold value with the insulin pump;
- and
- upon determining that the current blood glucose level is above the threshold, automatically calculating a revised correction bolus value with the pump from a preexisting correction bolus value, both the revised correction bolus value and the preexisting correction bolus value being calculated based upon the current blood glucose level.
1 more element
An insulin pump comprising:
- a pump mechanism;
- a memory configured to store one or more blood glucose levels;
- a programmable circuit arranged to control the pump mechanism and operatively connected to the memory, the programmable circuit programmed to:
- receive a current blood glucose level;
- determine whether the current blood glucose level is above a threshold value;
- and
- upon determining that the current blood glucose level is above the threshold value, automatically calculate a revised correction bolus value from a preexisting correction bolus value, both the revised correction bolus value and the preexisting correcting bolus value being calculated based upon the current blood glucose level.
4 more elements
An insulin pump comprising:
- a pump mechanism;
- a memory configured to store one or more rules, each rule including a threshold value and a percentage;
- a programmable circuit arranged to control the pump mechanism and operatively connected to the memory, the programmable circuit programmed to:
- prompt a user to input the threshold value and the percentage for at least one rule;
- receive a current blood glucose level;
- determine whether the current blood glucose level is above the threshold value;
- upon determining that the current blood glucose level is above the threshold value, automatically alter a preexisting correction bolus calculation factor representing an amount the user's blood glucose level drops for each unit of delivered insulin according to the at least one rule to define an altered correction bolus calculation factor;
- calculate a correction bolus value based upon the altered correction bolus calculation factor;
- and
- deliver the correction bolus to the user.
