  • Patent number: 10413223
    Abstract: A diagnostic tape unit and a process for producing it are provided, in which disposable, test units are applied to a rollable transport tape which is wound onto an unwinding spool and is connected to a take-up spool such that the test units can be successively made available to a user by winding on the transport tape. One or both of the leading end and trailing end of the transport tape is connected to their corresponding spools by means of an auxiliary tape.

  • Patent number: 9434141
    Abstract: A method for producing an analysis tape for fluid samples, in particular body fluids, is proposed. The method comprises providing a laminate tape having a laminate carrier tape and at least one diagnostic functional layer, and cutting the laminate tape in such a way that a diagnostic auxiliary label arises; transferring the diagnostic auxiliary label to a vacuum roller; and transferring the diagnostic auxiliary label to a carrier tape. In general, at least one vacuum roller is used for the transfer of the diagnostic auxiliary label to the carrier tape. The cutting of the diagnostic functional layer is effected in such a way that a free end of the diagnostic functional layer is lifted off from the laminate carrier tape by guiding the laminate carrier tape around a cutting edge with a small radius, wherein the diagnostic functional layer is cut at a predetermined distance from the lifted off free end by means of a cutting device.

  • Patent number: 8187537
    Abstract: The invention concerns a diagnostic test unit for analysing a body fluid comprising a test carrier (test tape 10; test strips 12) provided with test fields (38) for applying the body fluid and a container (14) containing the test carrier, wherein an opening (18) of the container (14) is at least in some areas bordered by a seal (16). According to the invention it is proposed that the opening (18) is screened by a closing foil (22) from the surroundings of the container (14) and that the test tape (10) or a test strip (12) to be dispensed is passed through a passage gap (20) between the closing foil (22) and the seal (16).
