  • Publication number: 20110004077
    Abstract: The present disclosure provides a container containing reference solution for clinical chemistry, whereby the container includes a closure part-covered outlet at which reference solution can be removed by puncturing with a puncturing element. The disclosure further provides a wick that is soaked with the reference solution and arranged in the container to extend from the outlet and such that a majority of its length extends into an interior space of the container.

  • Publication number: 20100286561
    Abstract: The invention concerns a test tape device for analyzing a body fluid having a carrier tape (36), a plurality of lancing elements (12) arranged on the carrier tape (36) which are provided with a tip (40) that can puncture a body part and a collecting structure (44) that takes up the body fluid obtained during the puncture, and test fields (14) mounted on the carrier tape (36) each being associated with a lancing element (12) and can have body fluid applied thereto. According to the invention it is proposed that the lancing elements (12) are each movably attached to the carrier tape (36) by a coupling member (38) and that a used lancing element (12) can be brought into contact with a test field (14) by a transfer movement from a usage position distant from a test field (14) into a contact position so that body fluid can be transferred from the collecting structure (44) onto the test field (14).

  • Patent number: 7008799
    Abstract: The invention concerns an analytical test element for the determination of an analyte in a liquid containing an inert carrier, a detection element and a channel capable of capillary liquid transport which has a sample application opening at one end and a vent opening at the other end of the channel capable of capillary liquid transport, wherein the channel capable of capillary liquid transport is formed at least partially by the carrier and the detection element and extends in the direction of capillary transport from the sample application opening at least to the edge of the detection test element that is nearest to the vent opening and wherein a notch is located in one of the surfaces forming the channel capable of capillary liquid transport at the edge of the test element forming the sample application opening so that one side of the edge of the test element forming the sample application opening is at least partially discontinuous and the surface opposite to the notch is exposed.

  • Patent number: 6696024
    Abstract: The invention concerns a device for the capillary transport of a liquid between two opposite, essentially planar layers, in which the two layers are arranged parallel to one another at such a distance that there is a capillary-active gap between the two layers, wherein at least one of the two layers contains at least two discrete adjacent parts and capillary-active transport of the liquid is possible beyond the common boundary of the parts that lie in one layer.
