Claim 17:
18. A diabetes management system comprising: a monitoring device configured to receive input data pertaining to a patient; a handheld computing device configured to receive the input data from the monitoring device; and an exogenous pharmacon on board (XOB) calculator configured to perform an XOB estimation using the input data, wherein the XOB calculator estimates an amount of pharmacon that will produce a glucose response that is closest to a predicted glucose response due to historical pharmacon administrations; and
wherein the XOB calculator comprises an XOB estimator, wherein the XOB estimator is configured to estimate a glucose equivalent effect of a pharmacon at a predetermined time, wherein the XOB estimator comprises a baseline time-series estimator, an iterative time-series comparator, and a time-series comparator, wherein the baseline time-series estimator is a stateless machine that receives historical XOB amounts and continuous glucose monitoring (CGM) system history and produces a time-series that approximates future values of glucose, wherein the iterative time-series comparator is configured to combine a procedure that generates candidate XOB amounts with a modification of the time-series estimator in which historical XOB amounts are substituted with the XOB amount under consideration, wherein the time-series comparator is configured to match a pair of time-series that can be any measure of distance or similarity between the series; and
an insulin pump or pen injecting or infusing an amount of insulin to the patient based on the XOB estimation for use in treatment of diabetes.
