Abstract:
A medical device comprising a personal assistive apparatus that computes the bio-availability of exogenous glucose and other nutrients contained in food, comprising:(a) an interface and control device that accepts user inputs, time stamps said inputs, and provides information for the assessment and control of ongoing metabolic states for an individual user; (b) a data storage device containing an addressable food database and software, wherein each entry in said food database is decomposed into elementary food categories; (c) a data storage device containing a plurality of coefficient values and time functions, wherein said coefficients and time functions describe the expected variation in time of one or more metabolites in vivo; (d) software and a means for computing and storing predicted input time functions; wherein one of said plurality of said time functions comprises the general formula: EG(t)=aNtNâˆ’1eâˆ’at/(Nâˆ’1)! or I(t)=bNtNâˆ’1eâˆ’bt/(Nâˆ’1)!â€ƒwherein: EG(t) is an elementary food component glucose activity time function; I(t) is an exogenous insulin time function; t is an elapsed length of time measured from the time stamp of entered data; a is the flux rate of elementary food categories; b is the flux rate of various insulin types; and N is the number of compartments.
