    摘要: This application relates to glucose monitoring systems for continuously measuring the glucose concentration in a patients blood. The system is adapted to communicate with one or more sensors (10, 20) for transcutaneous insertion into a patient and for producing sensor signals related to the glucose concentration. The system comprises an electronic calculator unit and a display (14) for displaying the measured glucose concentration. The electronic calculator unit further comprises means for calculating an estimate of the uncertainty, i.e. the degree of accuracy of the glucose measurement, and the display is configured for displaying an interval representing said uncertainty (15).

    摘要: This invention relates to procedures for the calibration of systems for continuously measuring the concentration of substances in a body fluid. The system comprises first and second sensors adapted for subcutaneous insertion and an electronic calculator unit adapted for measuring signals from the two sensors. The system is calibrated following the steps of: a) introducing the first sensor subcutaneously, b) calibrating the first sensor, c) obtaining sensor data S1(t) provided by the first sensor, d) introducing the second sensor subcutaneously, e) obtaining sensor data S2(t) provided by the second sensor, f) determining the rate of change over time δR(t)/δt, R(t) being a signal which correlates to sensor data S2(t) over time, and g) performing a calibration of the second sensor when δR(t)/δt is less than a predetermined value, said calibration of the second sensor being performed using sensor data S1(t) obtained by the first sensor.
