FIELD: manufacturing technology.
SUBSTANCE: multi-orientation test strip comprises a first layer having a first electrically conductive surface, a second layer having a second electrically conductive surface facing the first electrically conductive surface, and a separating layer disposed between the first and second layers and comprising a plurality of spacer portions arranged to form a plurality of adjacent sample chambers, having a plurality of corresponding inlet openings of sample chambers formed at the outer edges of the test strip, each of which is in fluid communication with a corresponding one of the sample chambers, said sample chambers extending between an outer edge and an inner edge of the test strip, each of the first layer, the second layer and the separating layer having a substantially circular shape, forming a substantially circular test strip during assembly, each of the sample chamber inlet opening is uniformly spaced along the outer edge of the test strip, and wherein the first layer comprises a central hole with a first diameter, the second layer comprises a plurality of curved openings defining a circular structure having a second diameter that is larger than the first diameter, and wherein the separating layer comprises a plurality of portions radially disposed at the outer edge of the test strip to form inlet openings of the sample chambers so that in the assembled test strip, the first conductive layer is exposed to action through the plurality of curved openings in the second layer, and the second electrically conductive layer is exposed to action through the central hole in the first layer.
EFFECT: invention provides the test strip that can be inserted into an instrumentation machine in various orientations, which allows the user not to pay attention to this when installing the test strip into the instrumentation machine, and it will take less time for the user to learn how to use the instrumentation machine correctly.
