Diagnostic test carrier
First Claim
1. A test carrier for determining analyte in a fluid sample, said test carrier comprisinga sample application zone comprising a first layer and a second layer and a gap between said first and second layers, said first and second layers being non-absorbent,an evaluation zone comprising a first layer and a second layer and a gap between said first and second layer, at least one of said layers being non-absorbent,said first and second layers in both of said zones being connected together by a plurality of discrete melt adhesive means having a thickness, said adhesive means positioned between said first and second layers so as to provide a plurality of intermediate spaces between said first and second layers, said intermediate spaces having a vertical dimension defining said gap separating said first and second layers, said vertical dimension being defined by the thickness of the melt adhesive means, said gap being dimensioned to assure a capillary action so that said fluid sample can spread out parallel to said first and second layers in a liquid transport path,said liquid transport path formed by said first and second layers in said sample application and said first and second layers in said evaluation zone, said transport path being parallel to said layers and extending through both of said zones.

Abstract
At least two layers are fixed together at a distance so that a gap is present between them, wherein the layers are connected with one another by a plurality of discrete melt adhesive regions, intermediate spaces being present between the melt adhesive regions so that a liquid transport in the gap between the layers is assured through the intermediate spaces. To produce this test carrier, the melt adhesive in the form of discrete regions, between which intermediate spaces are present, is applied to a first layer material in a thickness which is greater than the desired gap and a second layer material is pressed against the melt adhesive regions while the melt adhesive is still sufficiently hot in order to be bindable in such a manner that it binds with the melt adhesive but a gap remains between the layer materials.
