Abstract

A method for producing an analytical tape, in particular a lancet tape, is proposed. The analytical tape is designed for being used in an analytical testing device with at least a sample-taking function. In the method, at least one supporting tape is provided in a continuous process. A plurality of lancet elements are successively applied directly to the supporting tape at at least one application point.

Claims

1. A method for producing an analytical tape designed for being used in an analytical testing device with a sample-taking function, the method comprising:

providing a supporting tape wound on a first roller;

unwinding the supporting tape from the first roller in a transport direction and subsequently winding the supporting tape onto a second roller in a continuous process;

punching lancets from a lancet tape at a punching station; and

successively applying the lancets directly to the supporting tape at at least one application point between the first and second rollers, wherein each of the plurality of lancets comprises a puncturing component selected from the group consisting of a flat lancet and a round needle, each of the puncturing components being fixed directly on the supporting tape and being oriented pointing in a direction perpendicular to the transport direction, and wherein the combination of the supporting tape and the lancets forms the analytical tape configured having a constant thickness, the constant thickness being increased only at the lancets by the thickness of the lancets.

2. The method as claimed in claim 1, wherein the lancets comprise flat lancets, the flat lancets being applied with one flat side to the supporting tape.

3. The method as claimed in claim 1, wherein at least one biocompatible adhesive and/or at least one biocompatible adhesive layer are used.

4. The method as claimed in claim 1, wherein the supporting tape has at least one base layer and at least one adhesive layer.

5. The method as claimed in claim 4, wherein the base layer has a thickness of 2 to 20 micrometers.

6. The method as claimed in claim 5, wherein the base layer has a thickness of 6 to 12 micrometers.

7. The method as claimed in claim 4, wherein the adhesive layer has a thickness of 5 to 30 micrometers.

8. The method as claimed in claim 7, wherein the adhesive layer has a thickness of 10 to 20 micrometers.

9. The method as claimed in claim 1, wherein at least one continuous covering is additionally applied to the lancets.

10. The method as claimed in claim 9, wherein, for producing the continuous covering, at least one edge of the supporting tape is folded over the lancets after the lancets have been applied.

11. The method as claimed in claim 10, wherein the folded-over edge is connected to the non-folded-over supporting tape with a material bond.

12. The method as claimed in claim 11, wherein the folded-over edge is adhesively bonded and/or welded to the non-folded-over supporting tape.

13. The method as claimed in claim 9, wherein, for producing the continuous covering, at least one additional continuous covering tape is applied over the lancets.

14. The method as claimed in claim 13, wherein the covering tape has a thickness of 2 to 10 micrometers.

15. The method as claimed in claim 14, wherein the covering tape has a thickness of 4 to 8 micrometers.

16. The method as claimed in claim 1, wherein at least one stabilizing tape is additionally applied on a side of the supporting tape that is facing away from the lancets.

17. The method as claimed in claim 16, wherein the stabilizing tape has a thickness between 2 and 10 micrometers.

18. An analytical tape that can be produced as claimed in claim 1.

19. An analytical testing device, having at least a sample-taking function, comprising the analytical tape as claimed in claim 18, wherein the analytical testing device has at least one transporting means, the transporting means being designed for bringing one of the lancets respectively into a position for use, wherein the transporting means is designed for identifying the presence of one of the lancets on the basis of a change in thickness of the analytical tape.

20. An analytical device as claimed in claim 19, wherein the transporting means comprises a gripper.

21. An apparatus for producing an analytical tape, wherein the apparatus is designed for carrying out the method as claimed in claim 1, wherein the apparatus comprises at least one application apparatus, in order to successively apply the plurality of lancets directly to the supporting tape at at least one application point.

22. The method of claim 1, further comprising folding a portion of the supporting tape in a lateral direction perpendicular to the transport direction such that the lancets are at least partially covered by the portion of the supporting tape to protect the lancets from contamination, wherein the portion of the supporting tape is folded in the lateral direction after the lancets are applied to the supporting tape and before the supporting tape is wound onto the second roller.

23. The method of claim 1, further comprising aligning the lancet tape relative to the supporting tape using a plurality of positioning aides, wherein each of the positioning aides corresponds to one of the lancets of the lancet tape.

24. The method of claim 23, wherein the lancets are oriented on the lancet tape such that the lancets extend longitudinally in a direction perpendicular to a longitudinal direction of the lancet tape.

25. The method of claim 24, wherein the lancet tape includes a plurality of pairs of the positioning aides, each of the pairs of positioning aides is aligned with a corresponding one of the lancets.

26. The method of claim 23, wherein the positioning aides include a plurality of holes.

27. The method of claim 26, wherein each lancet is assigned one or more of the holes.

28. The method of claim 26, wherein each lancet is assigned precisely one or precisely two of the holes.

29. The method of claim 26, wherein the holes are provided on both sides of the lancets.

30. A method for producing an analytical tape designed for being used in an analytical testing device with a sample-taking function, the method comprising:

providing a supporting tape wound on a first roller;

unwinding the supporting tape from the first roller in a transport direction and subsequently winding the supporting tape onto a second roller in a continuous process;

aligning a lancet tape relative to the supporting tape using a plurality of positioning aides, the positioning aides being positioned in a predetermined spatial relationship to one or more of a plurality of lancets of the lancet tape;

punching the lancets from the lancet tape at a punching station; and

successively applying the lancets directly to the supporting tape at at least one application point between the first and second rollers, wherein each of the plurality of lancets comprises a puncturing component selected from the group consisting of a flat lancet and a round needle, each of the puncturing components being fixed directly on the supporting tape and being oriented pointing in a direction perpendicular to the transport direction, and wherein the combination of the supporting tape and the lancets forms the analytical tape configured having a constant thickness, the constant thickness being increased only at the lancets by the thickness of the lancets.
