Continuous monitoring method and monitoring equipment for analyte component concentration

摘要

Continuous monitoring of analytes, especially glucose, in humans and animals comprises producing a measured signal (z 1) related to a parameter which indicates the concentration of the analyte. The change in concentration with time is derived from this as a desired signal (y 1) using a filter algorithm in a time domain which allows errors in the desired signal to be reduced. The influence of actual measurements on the desired signal is used to derive a weighting factor. A signal fluctuation parameter is derived from actual measurements in a narrow time context and the weighting factor is modified in relation to the actual measurement at any given point in time. An independent claim is included for apparatus for carrying out the method using a sensor (12) which measures the parameter which indicates the concentration of the analyte.
