Abstract

A system suitable for collecting a body fluid, in particular blood from a body region of a person to be examined which comprises a lancing device which is suitable for holding a lancet, a lancet magazine for storing two or several lancets which has a transport device for the lancets and has an opening into which the lancing device can be inserted to remove a lancet from the lancet magazine, and two or several lancets, and which comprises a method for removing a lancet from a lancet magazine in which a lancet located in the lancet magazine is manually or automatically transported into a removal position in the interior of the lancet magazine, a lancing device is partially inserted into the opening provided in the lancet magazine in the process of which the lancing device automatically grips the lancet located in the removal position when it is partially inserted and the lancing device with the gripped lancet is removed from the lancet magazine.

Claims

1. A system for collecting bodily fluid, including:

a lancing device configured to receive a lancet; and

a lancet magazine configured to store a plurality of lancets, the lancet magazine including a housing that defines an interior space, an opening though which a portion of the lancing device is inserted such that the portion is within the interior space to remove the lancet, and a transport device configured to move within the interior space to transport the lancet toward a removal position.

2. The system of claim 1, wherein the plurality of lancets are arranged substantially radially in a plane.

3. The system of claim 1, further including the plurality of lancets.

4. The system of claim 3, wherein each lancet is disposed within the housing in contact with at least one other lancet.

5. The system of claim 1, wherein the housing includes a substantially rectangular cross-section.

6. The system of claim 1, wherein the lancet magazine includes a second opening through which protective sheaths coupled to the lancets may be ejected.

7. The system of claim 6, wherein the opening and the second opening are disposed on opposite sides of the housing.

8. The system of claim 1, wherein the transport device is configured for manual movement toward the removal position.

9. The system of claim 1, wherein the transport device includes a spring positioned within the interior space having a first end that engages the housing and a second end that engages a plate.

10. The system of claim 1, wherein the housing further includes a pin positioned adjacent the opening to engage a groove formed on the lancing device, thereby causing rotation of a portion of the lancing device upon insertion of the lancing device into the opening.

11. The system of claim 1, wherein the housing further includes a groove positioned adjacent the opening to guide a pin connected to the lancing device, thereby causing rotation of a portion of the lancing device upon insertion of the lancing device into the opening.

12. The system of claim 1, wherein the lancing device includes a barb configured to engage the lancet, thereby coupling the lancet to the lancing device.

13. The system of claim 1, wherein the opening has a substantially circular cross-section.

14. The system of claim 1, wherein each lancet includes a pin configured to engage the lancet magazine to prevent displacement of the lancet in one direction along a longitudinal axis of the lancet.

15. A system for collecting bodily fluid, including:

a lancing device; and

a lancet magazine including a housing that defines an interior space, a plurality of lancets disposed within the interior space, and a transport device at least partially enclosed within the interior space, the transport device being configured to engage one lancet to move another lancet toward a removal position wherein the other lancet is substantially enclosed within the interior space and situated for engagement with the lancing device.

16. The system of claim 15, wherein the lancet magazine includes an opening though which a portion of the lancing device is inserted such that the portion is within the interior space to engage the other lancet.

17. The system of claim 16, wherein the lancet magazine includes a second opening through which protective sheaths coupled to the lancets may be ejected.

18. The system of claim 15, wherein the transport device includes a spring positioned within the interior space.

19. The system of claim 15, wherein the plurality of lancets are arranged substantially radially in a plane.

20. The system of claim 15, wherein each lancet is disposed within the housing in contact with at least one other lancet.

21. The system of claim 15, wherein one of the housing and the lancing device includes a pin to engage a groove formed on the other of the housing and the lancing device, thereby causing rotation of a portion of the lancing device upon insertion of the lancing device into the housing.

22. A system for collecting bodily fluid, including:

a lancing device; and

a lancet magazine including a housing configured to store a plurality of lancets, and a transport device coupled to the housing, the transport device being configured to move each lancet in a first direction perpendicular to a longitudinal axis of the lancet toward a removal position wherein the lancet is positioned to engage the lancing device, each lancet remaining in a fixed orientation relative to the first direction until after engagement with the lancing device.

23. The system of claim 22, wherein the lancet magazine includes an opening though which a portion of the lancing device is inserted such that the portion is within the interior space to engage the lancet.

24. The system of claim 23, wherein the lancet magazine includes a second opening through which protective sheaths coupled to the lancets may be ejected.

25. The system of claim 22, wherein the lancet magazine and the lancing device are configured for interaction such that insertion of the lancing device into the lancet magazine causes rotation of a portion of the lancing device.

26. The system of claim 22, wherein the lancet is substantially enclosed within an interior space of the housing when in the removal position.

27. The system of claim 26, wherein the rotation of the lancing device causes separation of a protective sheath from a lancet located in the removal position.

28. The system of claim 22, wherein after engagement of the lancing device and the lancet positioned in the removal position, the lancet is moved in a second direction that is substantially perpendicular to the first direction, and a third direction that is substantially opposite the second direction.

29. A system for collecting bodily fluid, including:

a lancing device configured to receive a lancet; and

a lancet magazine including a housing, a plurality of lancets stored within the housing, each lancet including a body, and a transport device engaging at least one lancet to urge another lancet toward a removal position wherein the body of the other lancet is entirely enclosed within the housing.

30. The system of claim 29, wherein the lancet magazine includes an opening though which a portion of the lancing device is inserted to engage the body of the other lancet when the other lancet is in the removal position, thereby coupling the lancing device to the other lancet.

31. The system of claim 30, wherein the lancet magazine includes a second opening through which protective sheaths coupled to the lancets may be ejected.

32. The system of claim 29, wherein the other lancet remains in a substantially fixed orientation relative to a longitudinal axis of the other lancet as the other lancet is moved into the removal position.

33. The system of claim 29, wherein the plurality of lancets are coupled to one another.

34. A system for collecting bodily fluid, including:

a lancing device configured to receive a lancet; and

a lancet magazine including a housing configured to store a plurality of lancets, each of the lancets having a body, a needle attached to the body, and a protective sheath over the needle, and a transport device coupled to the housing, the transport device being configured to move each of the lancets toward a removal position for coupling with the lancing device.

35. A system for collecting bodily fluid, including:

a lancing device having a tip and a flexible holding tongue disposed within the tip, the tongue including a barb for engaging a lancet; and

a lancet magazine including a housing configured to store a plurality of lancets, and a transport device disposed within the housing, the transport device being configured to transport each of the lancets toward a removal position wherein the lancet is positioned adjacent an opening in the housing configured to receive the lancing device tip such that the barb of the flexible holding tongue engages the lancet, thereby coupling the lancet to the lancing device.
