ELECTRICAL CONNECTION SYSTEM FOR AN ELECTROCHEMICAL ANALYSIS SYSTEM
First Claim
1. An analysis system which analyzes a liquid sample provided on an analytical test element, said system comprising:
- an evaluation appliance which evaluates electrical signals;
a test element holder which holds and moves the test element from an initial position to a measurement position within the analysis system; and
an electrical contact element which is moveably retained by the test element holder, wherein the electrical contact element moves relative to the test element holder and into contact with a contact surface of the test element when the test element is moved from the initial position to the measurement position by the test element holder which makes an electrical connection between the contact surface and the evaluation appliance such that the liquid sample provided on the test element is analyzed by the evaluation appliance via electrical signals from the test element.

Abstract
An electrical connection system for an analysis system and a method for analysis of a liquid sample on an analytical test element using the described analysis system are disclosed. The analysis system provides an evaluation appliance for evaluation of electrical signals, a test element holder for holding and positioning of an analytical test element in a measurement position, and an electrical contact element which makes electrical contact with an electrical contact surface of an analytical test element to produce an electrical connection between the contact surface and the evaluation appliance. The contact element is moved by means such that contact with the electrical contact surface of the test element is made when the test element holder is in the measurement position.

21. A method for analysis of a liquid sample on an analytical test element, comprising:
-
moving the analytical test element to a measurement position in a test element holder in an analysis system; moving a contact element relative to the test element holder towards a contact surface of the test element in order to make electrical contact with the analytical test element and in order to produce an electrical connection between the contact surface and an evaluation appliance; and using the evaluation appliance to evaluate an electrical signal transmitted from the test element via the electrical connection.

22. A method for electrical connection of a contact surface of a test element in an evaluation appliance of an analysis system, comprising:
-
providing the analysis system which comprises a housing, a slide arranged in the housing, and the evaluation appliance which provides a contact element; inserting the test element into a holding space as far as a stop in the slide, the slide being moveable between an initial position and an end position, the slide being located in the initial position upon insertion of the test element and the contact element being set at a distance from the contact surface of the test element when the slide is in the initial position; and moving the slide with the test element contained in it from the initial position into the end position, wherein the contact element moves towards the contact surface of the test element and presses against the contact surface when the slide is moved into the end position.
