Lancet integrated test element tape dispenser
View Patent ↗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.
1. A method, comprising:
forming directly on a sterility sheet one or more electrodes for one or more test elements configured to analyze body fluid; and
folding the sterility sheet around one or more piercing members configured to pierce tissue, wherein each piercing member is associated with one of the test elements and the folded sterility sheet sandwiches the one or more piercing members therein.
2. The method of claim 1 , further comprising:
sterilizing the piercing members.
3. The method of claim 2 , wherein said sterilizing and said folding occur before said forming.
4. The method of claim 3 , further comprising:
applying a reagent on or near the one or more electrodes after said sterilizing.
5. The method of claim 2 , further comprising:
wherein said forming occurs before said sterilizing; and
applying a reagent on or near the one or more electrodes after said sterilizing.
6. The method of claim 5 , wherein said folding occurs before said sterilizing.
7. The method of claim 5 , further comprising:
attaching one or more spacers to the sterility sheet before said sterilizing; and
attaching one or more vent members to the sterility sheet before said sterilizing.
8. The method of claim 1 , further comprising:
sealing the sterility sheet around the piercing members.
9. The method of claim 1 , further comprising:
wherein the sterility sheet forms a tape; and
forming on the sterility sheet a plurality of guide members configured to guide the tape in a cartridge.
10. The method of claim 9 , wherein said forming on the sterility sheet the plurality of guide members comprises punching notches in the tape to define the guide members.
11. The method of claim 9 , further comprising:
wherein each piercing member is associated with one of the test elements to form an integrated sampling element; and
wherein said forming on the sterility sheet the plurality of guide members comprises locating the guide members on every other integrated sampling element.
12. The method of claim 9 , wherein the plurality of guide members extend from at least one edge of the tape.
13. The method of claim 1 , further comprising:
forming tractor holes in the sterility sheet.
14. The method of claim 1 , further comprising:
wherein the sterility sheet forms a tape;
wherein the folding the sterility sheet includes folding the tape to create a folded tape section; and
packing the folded tape section into a supply compartment of a cartridge.
15. The method of claim 14 , wherein said folding the tape includes folding the tape in a fanfold manner where adjacent sections of the tape contact one another.
16. A method, comprising:
forming a plurality of electrodes directly on a sterility sheet;
applying a reagent on the plurality of electrodes configured to analyze body fluid; and
folding the sterility sheet about a plurality of piercing members configured to pierce tissue, wherein each piercing member is sandwiched between a top layer and a bottom layer of the sterility sheet.
17. The method of claim 16 , further comprising:
sealing the sterility sheet around the piercing members.
18. The method of claim 16 , further comprising:
attaching a plurality of spacers to the sterility sheet; and
attaching a plurality of vent members to the sterility sheet.
19. A method, comprising:
forming directly on one sterility sheet one or more electrodes for one or more test elements configured to analyze body fluid;
folding the sterility sheet to form two flaps with a fold line between the two flaps; and
sandwiching one or more piercing members configured to pierce tissue between the two flaps of the sterility sheet, wherein one piercing member is associated with one test element.
20. The method of claim 19 , further comprising:
sterilizing the one or more piercing members.
