System for measuring an analyte concentration in a bodily fluid sample

Abstract

The invention relates to a system for measuring an analyte concentration in a bodily fluid sample, comprising a consumable material (3) with detection reagents that trigger a detection reaction upon contact with a bodily fluid sample, at least one magazine (2) containing such consumable material (3) for a plurality of measurements, a data carrier (6) attached to the magazine (2) containing calibration information for the consumable material (3) contained in the magazine (2), a handheld device (4) comprising a magazine receptacle (7) with a reader (10) for the purpose of accommodating such a magazine (2) and reading the data carrier (6) thereof, a measurement device (12) for measuring the result of a detection reaction, a processor (13) connected to the measurement device (12) and reader (10) for controlling the measurement device (12) and for analyzing a measurement signal. The invention provides for the system (1) to have, in addition to the at least one magazine (2) and the handheld device (4) at least one exchangeable data storage unit (5) as an additional system component, upon which supplementary data are stored that cooperate in the analysis of a measurement signal with calibration information stored on the data carrier (6) of a magazine (2) inserted into the device (4). The invention further provides for the handheld device (4) to have an interface (18) for transmitting supplementary data from the exchangeable data storage unit (5) to the device (4) and for a consumable material identifier to be stored on the data carrier (6) by means of which the processor (13) determines after the insertion of a magazine (2) whether a reliable measurement of an analyte concentration in a bodily fluid sample will be possible with the consumable material (3) in the inserted magazine (2) combined with the supplementary data available to the processor (13).

Description

technical field [0001] The invention relates to a system for measuring the analytical concentration of a body fluid sample, having the features given in the preamble of claim 1 . Such a system is known from EP 1 574 855 A1. Background technique [0002] For the examination of urine, blood, interstitial fluids or other body fluids, consumables are frequently used which have indicator reagents which produce an indicator reaction when they come into contact with the body fluid sample. The indicator reaction can lead, for example, to a fluorescence or a color change, which can be evaluated optically in order to determine the assay concentration. Indicator reactions are also known, for example, for the electrochemical determination of analytical concentrations. In general, an indicator reaction results in a change in a physically measurable parameter, wherein the magnitude of the change depends on the analyte concentration to be measured. [0003] Significant indication sensit...
