Abstract:
1. System for monitoring the concentration of analytes in body fluids, comprising a) a catheter having an implantable region and an outlet opening for the withdrawal of fluid, b) a first and a second analytical zone which, after contact with the withdrawn fluid, undergo a detectable change when an analyte is present in the fluid, c) a device configured to contact the first analytical zone with fluid from the catheter and to subsequently contact the second analytical zone with fluid from the catheter, d) an analytical device configured to analyze the changes on the analytical zones caused by the analyte-containing fluid in order to determine the concentration of an analyte to be monitored, and e) a pump configured to apply underpressure to the outlet opening in order to convey liquid, wherein the analytical device or an additional application detection device detects the presence of fluid or the presence of an adequate amount of fluid in or on the analytical zones and interrupts the application of the underpressure to the outlet opening based thereon, and wherein the first and second analytical zones are areas of a continuous test element, and the continuous test element is a tape.
