Embodiment Construction

[0022] figure 1 A test card-shaped support 1 on which a test area 2 for applying a liquid sample is formed is shown. The test region 2 communicates via a liquid channel 3 or directly without an intermediary with a test element 4 undergoing a detectable modification due to the analyte to be determined. This modification is detected eg optically or electrochemically by the detector 5 which generates an electronic detector signal as a function of it. If the test element 4 has biological or chemical components, such as enzymes, antibodies or microorganisms corresponding to the analyte to be determined, the test sensor 4 and the detector 5 together form a so-called biosensor. Examples of such sensor structures are known from US 5 997 817 or US 6 036 919 . If more than one analyte is to be determined from a liquid sample, an additional test element with a detector is naturally provided and communicated with the test zone 2 .

[0023] The detector 5 is connected to an evaluation cir...

Abstract

Sensor circuit to register an analyte in a liquid sample has a test element (4) with a test field (2) on a card (1) to take the liquid sample. Test element has a change through the specific analyte which is sensed by a detector (5), which generates a corresponding electrical signal. The test element and the detector together form a biosensor. Preferred Features: An evaluation circuit (6) establishes the analyte measurement through the detection signal, to be shown on a display (7). A power supply (10) with a solar cell (11) and a storage capacitance (12) provides the energy for the electrical components, which are at least partially formed by polymer electronics, as integrated plastics circuits (IPC). A control (8) prevents the test element being used for further tests.

Description

technical field [0001] The invention relates to a measuring device for determining an analyte in a liquid sample, which has the following device parts: with a test area for applying the liquid sample, undergoing a detectable modification due to the analyte to be determined The test element, as a detector whose function detects the modification and generates an electrical detector signal, is arranged downstream of the detector, an evaluation circuit evaluates the detection signal to form a measurement result, a display device connected to the evaluation circuit for displaying the measurement result , and a power supply for supplying electrical energy to electronic equipment components. Background technique [0002] Such a measuring device is known from US 6 300 141, which is formed on a support, for example having the shape and dimensions of a credit card, and comprising a lower support, both of which may be made of plastic and joined together by, for example, gluing and col...
