Abstract

A lancet integrated test element tape includes a plurality of lancet integrated test elements. The lancet integrated test elements each include a lancet configured to form an incision in tissue and a test element configured to analyze body fluid from the incision in the tissue. A cartridge includes a supply compartment configured to store an unused section of the tape. The tape is folded within the supply compartment to limit damage to the lancet integrated test elements. The cartridge can further include a waste compartment in which a used section of the tape is stored. An indexing mechanism moves the tape between the supply and waste compartments.

Claims (63)

1. A method, comprising:

creating a lancet integrated tape having lancets integrated with test elements;

forming on the lancet integrated tape a plurality of guide members configured to guide the tape;

loading the lancet integrated tape into a cartridge in which the guide members are received into a guide channel of the cartridge; and

wherein said creating the lancet integrated tape includes

joining a tape of the lancets and a tape of the test elements at least at alternating fold lines, and

folding the tape of the lancets and the tape of the test elements in an accordion manner in which the lancets and the test elements are folded away from one another.

2. The method of claim 1 , wherein said forming on the lancet integrated tape the plurality of guide members comprises punching notches in the lancet integrated tape to define the guide members.

3. The method of claim 1 , wherein said forming on the lancet integrated tape the plurality of guide members comprises locating the guide members on every other section of the folded lancet integrated tape.

4. The method of claim 1 , wherein the plurality of guide members extend from at least one edge of the lancet integrated tape.

5. The method of claim 1 , further comprising:

wherein said creating the lancet integrated tape includes

assembling on a sterility sheet the test elements, and

enclosing in a sterility sheet the lancets in which each of the lancets is associated with one of the test elements;

sterilizing the lancets; and

said assembling on the sterility sheet the plurality of test elements including

assembling one or more components of the test elements that are unaffected by said sterilization on the sterility sheet prior to said sterilization, and

assembling one or more components of the test elements that are affected by said sterilization on the sterility sheet after said sterilization.

6. The method of claim 5 , wherein:

the test elements are electrochemical sensors.

7. The method of claim 5 , wherein said enclosing comprises:

folding the sterility sheet around the lancets; and

sealing the sterility sheet around the lancets.

8. The method of claim 5 , further comprising:

folding the lancet integrated tape after said enclosing to create a folded tape section; and

wherein said loading the lancet integrated tape includes packing the folded tape section into a supply compartment of the cartridge.

9. The method of claim 1 , further comprising:

forming tractor holes in the lancet integrated tape.

10. The method of claim 1 , wherein said loading the lancet integrated tape includes packing the tape of the lancets and the tape of the test elements in the cartridge in a stacked manner.

11. The method of claim 1 , further comprising:

manufacturing the tape of the test elements to be wider than the tape of the lancets.

12. The method of claim 1 , wherein said creating the lancet integrated tape includes:

folding a sterility sheet around the lancets; and

sealing the sterility sheet around the lancets.

13. The method of claim 1 , further comprising:

sterilizing the lancets separately from the test elements.

14. A method, comprising:

folding a sterility sheet to form two flaps with a fold line in between;

sandwiching one or more lancet assemblies between the two flaps of the sterility sheet, wherein each of the lancet assemblies includes a lancet and a guide member with a slot opening through which the lancet extends, wherein said sandwiching includes aligning the slot opening of the guide member with the fold line of the sterility sheet so that the fold line of the sterility sheet closes the slot opening of the guide member;

sealing the lancet assemblies between the flaps of the sterility sheet to form one or more lancet packets; and

attaching one or more test elements to the lancet packets to form one or more lancet integrated test elements, wherein the test elements each have a capillary channel opening, wherein said attaching includes positioning the test elements so that the capillary channel opening of each test element is proximal to a corresponding slot opening.

15. The method of claim 14 , comprising:

wherein said attaching includes forming one or more electrodes of one or more electrochemical sensors on the sterility sheet;

sterilizing the lancets; and

applying reagent to the electrodes after said sterilizing.

16. The method of claim 14 , further comprising:

wherein said attaching includes creating a lancet integrated tape that includes the lancets and the test elements;

forming on the lancet integrated tape one or more guide members configured to guide the lancet integrated tape via one or more guide channels in a cartridge; and

loading the lancet integrated tape in the cartridge by inserting the guide members into the guide channel of the cartridge.

17. The method of claim 16 , wherein said forming on the lancet integrated tape includes punching notches in the lancet integrated tape to define the guide members.

18. The method of claim 16 , further comprising:

folding the lancet integrated tape after said enclosing to create a folded tape section; and

wherein said loading the lancet integrated tape includes packing the folded tape section into a supply compartment of the cartridge.

19. The method of claim 16 , wherein said forming on the lancet integrated tape the plurality of guide members comprises locating the guide members on every other section of the folded lancet integrated tape.

20. The method of claim 16 , further comprising:

forming tractor holes in the lancet integrated tape.

21. The method of claim 14 , wherein:

the test elements are electrochemical sensors.

22. The method of claim 14 , further comprising:

wherein said attaching includes creating a lancet integrated tape that includes the lancets and the test elements; and

wherein said loading the lancet integrated tape includes packing the tape of the lancets and the tape of the test elements in the cartridge in a stacked manner.

23. The method of claim 14 , further comprising:

sterilizing the lancets separately from the test elements.
