Analysis device with replaceable test field support
First Claim
1. A measuring device for analyzing a sample liquid for presence or concentration of at least one analyte, comprising:
- a measuring device body having an open position and a closed position;
evaluation electronics;
a test field support housed in the measuring device and coupled to the evaluation electronics, the test field support including a plurality of test fields, each test field of the plurality being accessible to a user when the measuring device body is in the open position;
each one of the plurality of test fields comprising an electrochemical measuring cell having a pair of sample sufficiency electrodes and a reagent adapted to react with a sample liquid to produce a response that is measurable by the evaluation electronics;
wherein the evaluation electronics are adapted to determine which one of the plurality of test fields has been wetted with the body fluid sample; and
wherein the device selectively provides visual indicia indicating which test fields of the plurality of test fields have been used and which remain unused.

Abstract
A measuring device for analyzing a sample liquid having at least one analyte is provided. A test field support housed in the device includes a number of individual test fields in communication with electrochemical measuring cells of the test field support. Reagents can be assigned to the electrochemical measuring cells which can react with a sample liquid. The reaction can lead to a measurable change of at least one quantity characteristic of the presence or concentration of an analyte in the sample. The measuring device includes evaluation electronics. The individual test fields on the test field support are accessible to the user after the measuring device has been opened.
