Abstract

The invention relates to a device and method for treating diabetic patients on insulin therapy. More specifically, the invention includes apparatus for infusing insulin into a patient in an amount determined by the patient'"'"'s carbohydrate intake, blood glucose level, and the amount of insulin calculated to be present in the patient at the time the therapy is to be administered. In one embodiment, an insulin infusion device having an on-board processor obtains a patient'"'"'s blood glucose value from a remote sensor and receives input from a user indicating their recent meal intake. The device may include an on-board food database for determining the carbohydrate content of the patient'"'"'s recent meals and compare that with recent insulin deliveries into the patient to determine the insulin present in the patient prior to determining an appropriate insulin dosage.

Claims

1. A method, comprising:

providing an insulin infusion device;

providing a blood glucose testing device that is in communication with the insulin infusion device;

determining a blood glucose value of a patient;

determining a quantity of insulin to deliver to the patient based on the blood glucose value of the patient;

delivering the quantity of insulin into the patient;

measuring a period of time following the delivery of the quantity of insulin;

comparing the period of time to an insulin-absorption curve;

determining an amount of insulin absorbed by the patient; and

determining an insulin on board amount, wherein the insulin on board amount equals the quantity of insulin delivered to the patient less the amount of insulin absorbed by the patient.

2. The method of claim 1, comprising selecting a quantity and type of food from a food database stored in the insulin infusion device.

3. The method of claim 2, comprising determining a carbohydrate content of the quantity and type of food.

4. The method of claim 3, wherein the quantity of insulin to deliver to the patient is determined based upon the blood glucose value of the patient and the carbohydrate content of the quantity and type of food.
