Patent ID: 8920341

Claim:
A test tape device for analyzing a body fluid for blood sugar tests having a carrier tape that can be wound onto or is wound onto a spool, 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 by the puncture, and test fields mounted on the carrier tape each being associated with a lancing element and can have body fluid applied thereto, characterized in 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 fluidic connection with a test field by a transfer movement executed by the lancing element from a usage position distant from a test field into a contact position, so that body fluid is transferred directly from the collecting structure onto the test field, wherein each lancing element is covered in a sterile manner by a cover foil connected to the carrier tape to form a foil bag around each lancing element, wherein the lancing element is configured to puncture the cover foil, characterized in that the test fields have a reagent layer which is designed to detect an analyte in the body fluid.
