Patent ID: 7658825

Claim:
A device for the detection and/or determination of the concentration of at least one analyte present in a liquid medium, consisting of a) a strip-shaped carrier ( 20 ) having two longitudinal edges ( 24 ), to which carrier ( 20 ) a printed multiple electrode set consisting of at least one reference electrode ( 30 ) and at least one working electrode ( 40 ) is applied and b) ligands which are suitable for binding a biologically active specific binding molecule or the analyte, wherein the device comprises a rigid reaction and detection chamber ( 50 ) adapted for continuous flow of the medium along said strip-shaped carrier ( 20 ), said reaction and detection chamber being formed by an elongated support ( 52 ) applied to said longitudinal edges ( 24 ) of said carrier ( 20 ) having a cover ( 54 ) disposed on said support ( 52 ), and that a liquid absorption element ( 60 ) is disposed downstream of said reaction and detection chamber ( 50 ), and further wherein the elongated support ( 52 ) is divided in two and is permanently adhesively attached, in the form of two strips, to the two longitudinal edges ( 24 ) of said carrier ( 20 ) and said strips only lie on one part of said two longitudinal edges ( 24 ) of said carrier ( 20 ), there being an interstice ( 70 ) between said strips and said liquid absorption element ( 60 ) from which interstice ( 70 ) said strips extend upstream on said longitudinal edges ( 24 ).
