Patent attributes
Devices, apparatuses and methods for controlling blood-glucose levels during exercise are described. For example, an insulin infusion apparatus can include a control module to regulate a rate of therapeutic fluid release into a body of a patient based on a determined therapeutic fluid requirement profile, and a dispensing unit to release therapeutic fluid at the regulated rate. The methods and devices can be implemented by receiving a first value corresponding to a first glucose concentration before an exercise activity of a user; receiving a second value corresponding to a second glucose concentration after the exercise activity for the user; determining a glucose concentration change based on a difference between the second value and the first value; modifying a basal rate based on a comparison of the glucose concentration change with a predetermined threshold value; and, recording the modified basal rate in a computer-readable memory device.
