Abstract

A diabetes care management system for managing blood glucose levels associated with diabetes comprising a computing device and an insulin delivery device. The computing device generally includes (i) a memory comprising one or more optimal blood glucose values, one or more self care values of a patient, one or more measured blood glucose values, and one or more scaling factors for weighting the impact on a future blood glucose value and that are customizable to an individual patient to predict the effect on the blood glucose of self care actions performed by the individual patient; (ii) a microprocessor, in communication with the memory, programmed to (A) determine the one or more scaling factors from one or more physiological parameters including body mass, metabolism rate, fitness level or hepatic or peripheral insulin sensitivity, or combinations thereof, and (B) calculate a further value, the further value being based on the self care values, and on the one or more optimal blood glucose values, and on the one or more scaling factors; and (iii) a display configured to display information according to the further value; and (iv) a housing, wherein the memory and the microprocessor are housed within the housing, thereby providing a hand-held, readily transportable computing device. The insulin delivery device may deliver insulin in response to information associated with the further value.
