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.

Claims

1. A method for producing an analysis tape for fluid samples, in particular body fluids, wherein the method comprises the following steps:

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,

wherein at least one vacuum roller is used for the transfer of the diagnostic auxiliary label to the carrier tape, wherein 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.

2. The method as claimed in claim 1, wherein the diagnostic auxiliary label comprises at least one of the following diagnostic aids:

a diagnostic test field with a test chemical designed to detect one or more analytes in the fluid sample; and

a lancet designed to perforate part of a patient'"'"'s skin in order to generate a fluid sample.

3. The method as claimed in claim 2, wherein the diagnostic auxiliary label alternately comprises lancets and diagnostic test fields.

4. The method as claimed in claim 1, wherein the laminate tape, the carrier tape and the vacuum roller are driven by drives wherein the drives are synchronized wholly or in part.

5. The method as claimed in claim 4, wherein a cutting device used for cutting the diagnostic functional layer is furthermore synchronized with the drives.

6. The method as claimed in claim 5, wherein the carrier tape is guided by means of an application roller at the location where the diagnostic auxiliary label is transferred, wherein the carrier tape is guided through a roller gap between the application roller and the vacuum roller.

7. The method as claimed in claim 6, wherein the application roller is a part of the drive of the carrier tape.

8. The method as claimed in claim 1, wherein the cutting of the diagnostic functional layer is effected using a CO₂ laser.

9. The method as claimed in claim 1, wherein the lifted off free end of the diagnostic functional layer is applied to the vacuum roller.

10. The method as claimed in claim 1, wherein the cutting is effected by the cutting device in the region of the cutting edge.

11. The method as claimed in claim 1, wherein the cutting of the diagnostic functional layer is effected in such a way that the diagnostic functional layer is converted into diagnostic auxiliary labels in a manner substantially free of losses.

12. The method as claimed in claim 1, wherein at least one of the laminate carrier tape and the carrier tape is charged electrostatically.

13. The method as claimed in claim 1, wherein in each case exactly one diagnostic auxiliary label is applied simultaneously on the vacuum roller.

14. The method as claimed in claim 1, wherein the diagnostic functional layer is provided with defect markings for marking defective sections of the diagnostic functional layer, wherein sections marked as defective are removed before or after application to the vacuum roller.

15. The method as claimed in claim 14, wherein the removal of the sections marked as defective is effected by extraction by suction.

16. The method as claimed in claim 15, wherein the extraction by suction is effected in the region of the vacuum roller.

17. The method as claimed in claim 1, wherein the diagnostic functional layer has a plurality of tracks of diagnostic aids that are arranged parallel in a running direction of the laminate tape, such that the diagnostic auxiliary label that arises when the diagnostic functional layer is cut has a plurality of diagnostic aids.

18. The method as claimed in claim 17, wherein the carrier tape is cut into sub tapes parallel to a running direction after the application of the diagnostic auxiliary labels.

19. The method as claimed in claim 1, wherein the carrier tape has reference marks for an optical calibration.

20. The method as claimed in claim 1, wherein the carrier tape furthermore has positioning marks.

21. A device for producing an analysis tape for fluid samples, the device comprising a laminate drive for supplying a laminate tape having a laminate carrier tape and at least one diagnostic functional layer to a labeling device, wherein the device furthermore has a cutting device for cutting the laminate tape, wherein the cutting device is designed to cut the diagnostic functional layer in such a way that a diagnostic auxiliary label arises, wherein the device furthermore has at least one vacuum roller, wherein the device is designed to transfer the diagnostic auxiliary label to the vacuum roller, wherein the device furthermore comprises a carrier drive for supplying a carrier tape to the labeling device, wherein the carrier drive and the vacuum roller are designed to interact in such a way that the diagnostic auxiliary label is transferred from the vacuum roller to the carrier tape, wherein the device is designed to carry out the cutting of the diagnostic functional layer 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.

22. The device as claimed in claim 21, wherein the laminate drive, the carrier drive and a vacuum roller drive for driving the vacuum roller are synchronized.

23. The device as claimed in claim 21, wherein the cutting device comprises a CO₂ laser.

24. The device as claimed in claim 21, wherein the device furthermore has a withdrawal device comprising an extraction device using suction, said withdrawal device being configured to remove defective sections of the diagnostic functional layer before or after application to the vacuum roller.

25. The device as claimed in claim 21, wherein the device furthermore has a defect identification device for identifying defective incipient cuts of at least one of the diagnostic functional layer and the laminate tape.

26. The device as claimed in claim 21, wherein the device furthermore has a defect marking device for marking defective incipient cuts of at least one of the diagnostic functional layer and the laminate tape.

27. The device as claimed in claim 21, wherein the device furthermore has, in the region of the labeling device, a detection device for identifying incipient cuts of at least one of the diagnostic functional layer and the laminate tape which have been marked as defective.
