  • Patent number: 10274430
    Abstract: Methods, analytical devices and analytical systems are provided for determining at least one analyte concentration in a body fluid sample. The methods, which may be incorporated into the devices and systems, can include the following steps: applying a body fluid to a test carrier; illuminating the test carrier by at least one light source, where the at least one light source is modulated by using at least two modulation frequencies; receiving light remitted by the test carrier by using at least one detector; determining an analyte concentration by evaluating at least one detector signal generated by the detector, where the detector signal is demodulated with the at least two modulation frequencies to generate at least two demodulated detector signals, each demodulated signal corresponding to one of the modulation frequencies; and detecting a fault by comparing the at least two demodulated detector signals.

  • Patent number: 7951331
    Abstract: The invention relates to embodiments of an analysis system and to a method for analyzing a sample on an analytical test element, with the analysis system comprising a test element receptacle for receiving and positioning a test element in an analysis position. In an exemplary embodiment, the test element receptacle contains a guide part and a lock part, the guide part having means for guiding a test element into and out of the analysis position, the lock part comprising a frame and a bolt element, which frame and bolt element are connected to one another by a hinge. The bolt element can be pivoted about the hinge between a first position and a second position with respect to the frame. The bolt element comprises a latching lug for engaging in a recess in test element when the bolt element is in the first position and when the test element is positioned in the analysis position.

  • Patent number: 7477404
    Abstract: The invention relates to embodiments of a method and a system for monitoring the correct positioning of a test element in a test element receptacle of an analysis unit, the test element carrying a sample to be analyzed by the analysis unit. Using a delimiting element, responsive signals resulting from irradiating an analysis region on the test element are effectively prevented from impinging upon a signal detector when the analysis region is in an incorrect position relative to the analysis unit. The delimiting element is provided with a light-opaque region and a light-transmissive region, and the light-opaque region is positioned such that responsive signals impinge upon it rather than the light-transmissive region when the analysis region is in an incorrect position.

  • Publication number: 20080087819
    Abstract: The invention relates to a method for analyzing a fluid sample, such as a body fluid sample in which, after loading a test element with a sample of a fluid, the fluid sample passes into a detection area of the test element and spreads out in the detection area, and in which a filling extent which characterizes the spread of the fluid sample in the detection area is determined using a photometric measurement of the fluid sample in the detection area, wherein the photometric measurement is carried out by means of a first light which is irradiated onto the fluid sample in the detection area, said first light having a first wavelength for which, when at least one chemical parameter of the fluid is varied, the fluid has an essentially constant optical behaviour with respect to at least one spectroscopic parameter selected from a group of spectroscopic measurement parameters consisting of absorption, transmission, remission and fluorescence, and wherein the at least one chemical parameter of the fluid comprises at
