  • Patent number: 8821790
    Abstract: The invention concerns a diagnostic tape unit with a test tape that can be wound onto a spool which comprises a transport tape and a plurality of test elements mounted thereon, where the test elements have an analytical reagent layer, a carrier foil supporting the reagent layer and a piece of adhesive tape connecting the carrier foil with the transport tape, and where the front side of the reagent layer facing away from the carrier foil is designed for the application of a sample substance. According to the invention it is proposed that the test elements in combination with the light transmitting transport tape in each case form an optical multi-layer system for a rear-side reflection-photometric measurement of the reagent layer.

  • Patent number: 7975842
    Abstract: The invention relates to a packaging system for medical consumables, in particular test elements. The packaging system comprises an outer packaging, which accommodates a first desiccant supply, and a magazine with an unused test element supply. In the closed state of the outer packaging, the first desiccant supply of the outer packaging acts on the interior of the magazine via a connection that permits water vapor diffusion. In exemplary embodiments, the magazine includes a second desiccant supply. The communication of water vapor between the magazine and outer package reduces the load on the desiccant supply in the magazine.

  • Patent number: 7479253
    Abstract: A flat-shaped functional overlay for at least one region of a flat-shaped flexible object which does not form a fold when the sandwich composed of the flexible object and overlay is bent towards the side on which the overlay is located is described. The overlay is composed of one or several flat-shaped overlays which are attached to the flexible object in such a way that a part of their surface can move freely relative to the surface of the object covered by this part in the direction of curvature produced when the object is bent. In addition diagnostic test strips are described which have such an overlay.

  • Patent number: 6055060
    Abstract: Analytical system for evaluating test elements having means of determining whether a sufficient amount of sample liquid was evenly applied to an application zone comprising in a first embodiment of the invention at least two sources of light which illuminate separate or at least not fully overlapping areas of the application zone or the evaluation zone of the test strip, a control unit with which the light sources, of which there at least two, can be independently activated, at least one sensor which detects light reflected by the evaluation zone or transmitted by the evaluation zone and supplies an output signal proportional to the intensity of light as well as an evaluation unit which receives a first output signal from the sensor and converts it into a first measured value when the first of the light sources is activated, receives a second output signal from the sensor and converts it into a second measured value when the second of the light sources, is activated and compares the measured values and determ
