The invention relates to a test element analysis system (1) for analytical investigation of a sample, in particular a body fluid, comprising at least one test element (3) with one or more measuring zones (7), contact surfaces (11) located on the test element (3), in particular, electrodes or conductors, whereby the sample under investigation is applied to the measuring zone (7) to perform an analysis by determination of a parameter characteristic for the analysis, and an analytical device (2) with a test element retainer (5) for positioning the test element (3) in a measuring position and a measuring device for measuring the characteristic change, whereby the test element retainer (5) comprises contact elements (14) with contact surfaces (12) which permit an electrical contact between the contact surfaces (11) of the test element (3) and the contact surfaces (12) of the test element retainer (5), characterised in that one of said contact surfaces is provided with an electrically-conducting hard material surface (20). The invention relates particularly to the coating of a contact surface (12) of the contact connection on a test element analysis device with an electrically-conducting hard material.

The invention relates to a microfluidic element for analyzing a body liquid sample for an analyte contained therein, comprising a substrate (5) and a channel structure (2) enclosed by the substrate (5) and a cover layer, wherein the element can be rotated about a rotational axis. The channel structure (2) of the microfluidic element (1) encloses a feed channel (6) having a feed opening (9), a vent channel (10) having a vent opening (11), and at least two reagent chambers (12). The reagent chambers (13) are connected to each by means of two connecting channels (14) such that a fluid exchange is possible between the reagent chambers (13) and one of the reagent chambers (13) comprises an inlet opening (23), which is in fluid connection with the feed channel (6), so that a liquid sample can flow into the reagent chamber (13a) that lies farther away from the rotational axis. At least one of the reagent chambers (13) contains a reagent (35), which reacts with the liquid sample.

摘要:
The invention relates to the field of analysis systems, in which a sample analysis is carried out using test strips. According to the invention, the analysis system comprises a transport unit (1), which is driven by piezo-active elements (2). The transport unit (1) permits the direct or indirect transport of test strips in such a way that analysis methods can be wholly or partly automated. The invention also relates to a transport unit for transporting a test strip (15), said unit being controlled by an optical detector that detects the test element (15) in the system.

The present invention relates to a microfluidic test carrier (1) for dividing a liquid quantity into subquantities. It comprises a substrate (4) and a covering layer (21) and also a capillary structure (3) formed in the substrate (4), which capillary structure is enclosed by the substrate (4) and the covering layer (21). The capillary structure (3) comprises a receiving chamber (6), at least one sample chamber (8, 10, 11) and a connection channel (9) between the receiving chamber (6) and the sample chamber (8, 10, 11). The receiving chamber (6) has two opposite boundary surfaces (22, 23) and a side wall, wherein the one boundary surface (22, 23) is the bottom (24) of the receiving chamber (6) and the other boundary surface (22, 23) is the cover (25) of the receiving chamber (6). The receiving chamber (6) has a surrounding venting channel (16) and a surrounding dam (18) which is arranged between the receiving chamber (6) and the venting channel (16). The dam (18) is constructed in such a manner that, together with the venting channel (16), a capillary stop formed as a geometric valve (28) is formed, through which air from the receiving chamber (6) can escape into the venting channel (16). The connecting channel (9) between an outflow orifice (26) of the venting channel (16) and an inlet orifice (35) of the sample chamber (8, 10, 11) is a central control element and makes possible fluid transport from the receiving chamber (6) into the sample chamber (8, 10, 11). The capillary stop is constructed in such a manner that autonomous fluid transport from the receiving chamber (6) is prevented.

摘要:
Apparatuses and methods providing data such as, for example, calibration and reagent information (30) over a network (6) to a measurement apparatus (4) which makes use of a consumable reagent (18) in a measuring process are disclosed. The present invention permits a measurement apparatus (4) to download the necessary code assignment (24) and calibration data (32) of the consumable reagent (18) by means of an electronic communication protocol from a host (33). The host (33) can be a software application running on a host computer (34), another measurement apparatus (50, 58) with or without a code-key slot used to read a memory device providing the above mentioned information (30), a dedicated connectivity device, such as a docking station (44), a portable memory reader (48), a remote computer (54), and combinations thereof.
