15. A multi-use lancet device as recited in claim 13 wherein said lancet receiving assembly is at least partially removably coupled to said firing assembly so as to permit access to said access openings.

16. A multi-use lancet device as recited in claim 1 wherein said lancet receiving assembly includes at least two guide regions wherein each of said lancets is movably disposed.

17. A multi-use lancet device as recited in claim 16 wherein each of said guide regions is operatively associated with a piercing opening wherethrough a tip of said lancet protrudes upon movement between said cocked and said fired orientations.

18. A multi-use lancet device as recited in claim 17 further comprising a shielding assembly structured to expose at least one of said piercing openings at a time.

19. A multi-use lancet device as recited in claim 18 wherein said shielding assembly exposes only said piercing opening of said active lancet at a time.

20. A multi-use lancet device as recited in claim 16 wherein each of said lancets includes a removable tip guard structured to cover said tip of said lancet until use.

21. A multi-use lancet device as recited in claim 20 wherein said tip guard includes an enlarged configuration structured to be maintained exterior of a corresponding one of said guide regions at said piercing opening.

22. A multi-use lancet device as recited in claim 20 further comprising a shielding assembly structured to expose only one of said tip guards at a time.

23. A multi-use lancet device as recited in claim 1 wherein said lancet receiving assembly is removably coupled to said firing assembly.

24. A multi-use lancet device as recited in claim 1 wherein said firing assembly includes an engagement element structured to operatively engage said active lancet so as to result in movement of said active lancet between said cocked and said fired orientations.

25. A multi-use lancet device as recited in claim 24 wherein said engagement element is movably disposed between a cocked and a fired orientation so as to correspondingly move said active lancet between said cocked and said fired orientations thereof.
