  • Patent number: 8920341
    Abstract: The invention concerns a test tape device for analyzing a body fluid having a carrier tape, a plurality of lancing elements arranged on the carrier tape which are provided with a tip that can puncture a body part and a collecting structure that takes up the body fluid obtained during the puncture, and test fields mounted on the carrier tape each being associated with a lancing element and can have body fluid applied thereto. According to the invention it is proposed that the lancing elements are each movably attached to the carrier tape by a coupling member and that a used lancing element can be brought into contact with a test field by a transfer movement from a usage position distant from a test field into a contact position so that body fluid can be transferred from the collecting structure onto the test field.
