Title (EN) USE OF MULTIPLE DATA POINTS AND FILTERING IN AN ANALYTE SENSOR
(FR) UTILISATION DE POINTS DE DONNEES MULTIPLES D'UN FILTRAGE DANS UN DETECTEUR D'ANALYTE
Abstract:
(EN) Embodiments of the present invention improve the accuracy of measurements and/or in vivo calibrations of a biosensor by (1 ) using more than one sensor signal value and/or more than one directly sampled and measured value, such as a capillary blood glucose value, and/or by (2) delaying the acquisition of a sensor output value that is compared with a directly sampled and measured value, such as a capillary blood glucose value, during a calibration. In an embodiment of the present invention, the median of a series of measured values, or a median or mean of the medians, may be utilized to provide more consistent and accurate measurement data and/or to compensate for error or artifact.
(FR) Dans différents modes de réalisation, ce procédé permet d'améliorer la précision des mesures et/ou de l'étalonnage in vivo d'un biocapteur, par (1 ) l'utilisation de plusieurs valeurs de signaux du capteur et/ou de plus plusieurs valeurs échantillonnées et mesurées directement, telles que la glycémie capillaire, et/ou par (2) retardement de l'acquisition de la valeur de sortie du capteur, qui est comparée à une valeur échantillonnée et mesurée directement, par exemple à une valeur de glycémie capillaire, au cours de l'étalonnage. Dans un mode réalisation, ce procédé comprend l'utilisation de la médiane d'une série de valeurs mesurées, ou d'une médiane ou moyenne des médianes pour obtenir des données de mesure plus précises et plus pertinentes et/ou pour compenser les erreurs ou les artefacts.
