Apparatus for the evaluation of a test carrier for the analytical determination of components of a body fluid
First Claim
1. An apparatus for the evaluation of a flat test carrier, said test carrier including a covering layer fixed as a flap on one edge of the test carrier, comprising a positioning means which positions and firmly holds said test carrier in a measurement position against a measuring unit which comprises an aperture element with a contact surface which contacts the covering layer of said test carrier, at least one of said aperture element and said positioning means being pivotally mounted to contact said contact surface of said aperture element and said covering layer of said test carrier held in said positioning means by pivoting said at least one of said positioning means and said aperture element about a pivoting axis which lies in close proximity to the edge of said test carrier held in said positioning means.

Abstract
According to a second aspect, the present invention also provides an apparatus for the evaluation of a flat test carrier for the analytical determination of components of a body fluid, said apparatus having a measurement unit and a positioning means, by means of which the test carrier is positioned and firmly held in a measurement position in such a manner that its test field is present in a definite position with regard to the measurement unit, wherein, for the evaluation of test carriers with a covering layer fixed in the manner of a flap on one edge of the test carrier, there is present a shutter element with a contact surface for pressing on the covering layer, the aperture element and/or the positioning means being mounted and operable in such a manner that the contact surface in the last phase of approaching the covering layer makes, relative to the test carrier, a tilting movement about a tilting axis which lies in close proximity to a fixing edge of the covering layer.
