Patent ID: 7641857

Claim:
A disposable one piece measuring apparatus for determining an analyte in a liquid sample comprising: a one piece substrate; and on the substrate: a plurality of test elements; a plurality of test fields each corresponding to a different test element for applying the liquid sample to the different test element, the different test elements each experiencing a detectable modification due to the analyte to be determined in response to the applied sample; and a plurality of electrical components comprising: a detector which corresponds to each test field and test element and detects the modification and generates an electrical detector signal as a function of the detected modification; an evaluation circuit coupled to the detector to evaluate the detector signal and generate a measurement result; a display device connected to the evaluation circuit for displaying the measurement result; and an electrical power supply for supplying electrical power to the electrical components comprising the detector, evaluation circuit, and display device wherein at least a majority of the electrical components are formed on the basis of polymer electronics; wherein the test fields are arranged at an edge region of the substrate in zones separated from one another by break lines and in that each zone is arranged to be broken off from the substrate at the break lines after the test field lying in it has been used.
