摘要:
The invention relates to an analytical test tape (20), particularly for use in a test tape cassette (14), with a carrier tape that can be wound onto a spool and a plurality of test elements (24) distributed on the carrier tape in the longitudinal direction of the tape, said elements comprising a spreading fabric (30) for applying a body fluid and a reagent layer (36) thereunder for detecting an analyte in the body fluid, wherein the spreading fabric (30) is formed from fabric threads (44,46) crossed in a lattice shape. The invention proposes that the rigidity of the spreading fabric (30) is modified in certain areas.

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 describes systems and methods for optically imaging objects and in particular optical patterns or codes onto a detection device by means of a pinhole aperture. According to the invention these systems have optical attenuation elements between the illumination devices and the object which substantially compensate the system-inherent imaging defects caused by the pinhole aperture and in particular the system-inherent peripheral decrease in brightness of an image of the object formed by a pinhole aperture on the detection device. According to the invention the optical attenuation elements change the illumination intensity of the object in such a manner that the central areas of the object are illuminated at a lower light intensity than its peripheral areas. As a result of the subsequent imaging of the object by means of a pinhole aperture, the central areas of the object are imaged onto the detection device at a higher light intensity than the peripheral areas of the object. The superimposition of the two effects enables the imaging system according to the invention to achieve a substantially uniform system-inherent brightness distribution on the detection device.
