VORRICHTUNG ZUM LAGERICHTIGEN ZUFÜHREN VON TESTSTREIFEN ZU EINER ANALYSEEINRICHTUNG

摘要

Apparatus for feeding correctly oriented test strips to an analyser. The test strips 10 have a base layer and at least one raised test field attached to one side of the base layer. The test strips are present in a reservoir in a random arrangement with respect to the rotational position of their longitudinal axes. An isolating and orientation correction device 1 is used to feed the test strips 10 individually and successively in a defined orientation to the analyser. …A simple construction and reliable functioning is achieved by the isolating and orientation correction device 1 having an orientation correction stage 30 with two rollers, between which there is a narrow gap 35. The rollers rotate in such a way that the lateral face 31a of the first roller 31 in the region of the gap 35 moves downwards, while the lateral face 32a of the second roller 32 moves upwards. The first roller 31 has revolving raised webs 37 which are aligned with test field-free regions of the test strips 10. The second roller 32 is provided with followers 38 which run parallel to the axis. The width of the gap 35 in the regin of the raised webs 37 is smaller than the thickness of the test strips including the test field. ……
