ANALYTICAL SYSTEM FOR MONITORING A SUBSTANCE TO BE ANALYZED IN PATIENT BLOOD

摘要

Analytical system for monitoring patient blood concentration of a substance to be analyzed, comprising analysis-elements (12) containing reagents and an evaluation instrument comprising a measurement device to measure a change resulting from a reaction of the analyte with the reagents in order to determine, from the measurement values so obtained, analytical data representing element analysis data CA. In order to allow continuous monitoring of the analyte with good accuracy and a reduced number of invasive sample generation steps it is proposed that the analytical system further comprises (i) a sensor unit (2) portable on the patient body, said sensor unit (2) including a sensor (7) borne on the patient body for the direct and reagent-free measurement of a parameter correlating with the concentration of the analyzed substance and a transmitter for the wireless transmission of data signals; and (ii) a sensor-analysis means to ascertain sensor-analysis data CS from the measurement values of said parameter measured by said sensor; and the evaluation instrument further comprises a receiver to receive in wireless manner the data signals from the sensor unit (2), calibration means to calibrate the sensor-analysis data CS on the basis of the element-analysis data CAand (iii) a data memory for the long-term storage of analytical data, whereby said evaluation instrument forms a central unit (3) of an integrated analysis-element/sensor monitoring system (1).
