Abstract
An apparatus comprises receiving a user prompt in a blood glucose (BG) management device to start a determination of an effective correction factor, receiving sampled blood glucose data of a patient obtained during a specified time duration, including a time duration after delivery of an initial insulin correction bolus, determining the effective correction factor using the BG management device according to a determined decrease in the blood glucose level of the patient and an amount of insulin in the initial insulin correction bolus, and cancelling the determination of the effective correction factor if a blood glucose level of the patient is outside of a specified range of blood glucose levels.

2. An ambulatory insulin pump system, comprising:
-
a pump configured to deliver insulin to a user; a user interface including a display; a memory; and a controller in electrical communication with the pump, the memory and the user interface, the controller configured to determine an effective correction factor for the user by conducting a correction factor test, the correction factor test comprising; receiving sampled glucose level data of the user obtained during a specified time duration; causing the pump to deliver an initial insulin correction bolus to the user during the specified time duration; determining from the sampled glucose level data a decrease in the glucose level of the user during the specified time duration; calculating an effective correction factor for the user based on the decrease in the glucose level and an amount of the initial insulin correction bolus; and saving the effective correction factor in memory. - View Dependent Claims (3, 4, 5, 6, 7, 8, 9, 10)

11. An ambulatory insulin pump system for delivering insulin to a user, the insulin pump system having a controller, the controller being programmed with an algorithm configured to:
-
receive input data related to a first user glucose level; initiate infusion of a known predetermined quantity of insulin to the user; record a time of the infusion of the known quantity of insulin; wait a length of time after the infusion of the known quantity of insulin; receive input data related to a second user glucose level; calculate a change in glucose level between the first user glucose level and the second user glucose level; calculate a correction factor for the user by diving the change in glucose level by the known predetermined quantity of insulin; save the correction factor in memory; receive input of a current glucose level and target glucose level; calculate an insulin dose to bring the current glucose level to the target glucose level using the calculated correction factor; and deliver the calculated dose to the user. - View Dependent Claims (12, 13, 14, 15)

16. An ambulatory insulin pump system, comprising:
-
a pump configured to deliver insulin to a user; a user interface including a display; a memory; and a controller in electrical communication with the pump, the memory and the user interface, the controller including a timer, a correction factor module and an insulin calculation module and configured to; receive sampled glucose level data of the user obtained during a specified time duration; cause the pump to deliver an initial insulin correction bolus to the user during the specified time duration; determine from the sampled glucose level data a decrease in the glucose level of the user during the specified time duration with the correction factor module; calculate with the correction factor module an effective correction factor for the user based on the decrease in the glucose level and an amount of the initial insulin correction bolus; and save the effective correction factor in memory. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23)
