1. A biosensor strip for determining the concentration of an analyte in a sample of biological liquid, the biosensor strip comprising:

  • (a) an electrode support;

    (b) an electrode arrangement on said electrode support;

    (c) a cover;

    (d) a sample flow channel having a proximal end where a liquid sample is introduced into the sample flow channel, a distal end toward which the liquid sample flows when it has been introduced into the sample flow channel, a first side extending between the proximal end and the distal end of the sample flow channel, and a second side extending between the proximal end and the distal end of the sample flow channel, the first side and the second side serving to retain the liquid sample in the sample flow channel; and

    (e) an incompressible element placed between said cover and said electrode support, said incompressible element providing an opening in at least one side or in the distal end of said sample flow channel to provide at least one vent in said sample flow channel.
