Apparatus and method for monitoring blood glucose levels including convenient display of blood glucose value average and constituent values

摘要

An effective meal average (EMA) value is presented, followed by two or more of the individual values that make up the EMA, to provide improved feedback data for clinical decisions by patients who need to alter their dose of insulin. The EMA can comprise a measure of the variability of its constituent values, encompass values that occur at specified times such as 1 hour before and after a specified meal time, and be calculated over a limited number of days previous to the calculation (e.g., 3 days) and have a minimum number of values that must be obtained within the time and date ranges. An algorithm can exclude any given reading from the average (e.g., post-prandial or control solution readings). Patients can use 1 to 8 EMA on any given date range (e.g., preferably 4, that is, breakfast, lunch, supper and bedtime snack).

主权项

1. A method of annunciating a patient's medical data levels using a medical data level monitoring device comprising the steps of:
storing medical data levels in a memory device with the corresponding dates and times of day the respective medical data levels were taken; selecting a time period and a corresponding subset of the stored medical data levels comprising stored medical data levels taken during the time period; calculating using a processing device an average medical data level using at least n stored medical data levels selected from the subset of stored medical data levels where n is an integer greater than or equal to 2, the n stored medical data levels being constituent values of said average medical data level; sequentially annunciating said average medical data level and respective ones of the constituent values comprising annunciating said average medical data level, receiving a first user input to annunciate a first medical data level from among the constituent values, annunciating said first medical data level,receiving a second user input to annunciate a second medical data level from among the constituent values, andannunciating said second medical data level;wherein each of the annunciating steps comprises displaying a corresponding one of said average medical data level and said constituent values on a display screen, the display screen comprising a first area for displaying one value selected from the group consisting of the average medical data level and said constituent values, and second area configured to simultaneously display n indicators corresponding to respective ones of said n stored medical data levels at least when one of said constituent values is displayed, and the annunciating steps for displaying said constituent values comprises displaying one of said n indicators corresponding to the constituent value currently being annunciated differently from the other ones of said n indicators in the second area to indicate which of said constituent values is currently being annunciated.
