Abstract

Disclosed is a capillary sensor analysis system for analyzing a body fluid o f humans or animals, comprising capillary sensors that are provided with a capillary duct which is enclosed by at least two wall parts and contains reagents, and an evaluation device (2) which is provided with a capillary sensor holder (23) in order to place a capillary sensor (14) in a measuring position (22) so as to perform an analysis such that the inlet port (13) thereof is accessible for bringing a sample liquid that is to be analyzed in to contact therewith, the sample liquid penetrating into and filling the capillary duct due to capillary forces. The capillary sensors are embodied a s multiple capillary sensor strips (3) having a plurality of capillary sensors (14) that are disposed one behind another. A multiple capillary sensor strip (3) is guided and held within the capillary sensor holder (23) of the evaluation device (2) such that one capillary sensor (14) of the strip (3) i s located in the measuring position (22) and the inlet port (13) thereof is accessible so as to be brought into contact with sample liquid (19) while th e multiple capillary sensor strip (3) is movable within the evaluation device in such a way that successive capillary sensors of the multiple capillary senso r strip (3) are conveyed into the measuring position (22).
