Method and system for management of diabetes with a glucose monitor and infusion pump to provide feedback on bolus dosing
First Claim
Patent Images
1. A method for operating a diabetes management system having an infusion pump, at least one glucose monitor and a microcontroller, the method comprising the following steps performed with the microcontroller:
- determining a glucose measurement in which a fluid sample with glucose is transformed into enzymatic byproducts by application of electrical signals to the sample;
calculating a bolus recommendation based on the glucose measurement made by the determining step;
evaluating whether the bolus recommendation was followed by a user of the system;
in the event the bolus recommendation was not followed by the user then;
storing the actual bolus delivered by the infusion pump;
measuring the glucose value in subsequent fluid samples and if the glucose values over time is greater than a predetermined high trend threshold then annunciating a high glucose trend, along with the recommended bolus and the actual bolus delivered by the pump otherwise if the glucose values over time is less than a predetermined low trend threshold then annunciating a low glucose trend along with both the recommended bolus and the actual bolus delivered by the pump.

Abstract
Described and illustrated is a system for management of diabetes that includes an infusion pump, glucose sensor and controller with a method programmed into the controller. The infusion pump is configured to deliver insulin to a subject. The system provides the user with the ability to understand the effects of bolus insulin dosing upon their glucose levels. Specifically, the system provides a message that must include: (a) the trend of the user'"'"'s glucose; (b) the recommended bolus; and (c) the actual bolus.
