Abstract

A system for analyzing a bodily fluid is described, which contains at least one lancing element, such as a lancet, stored in a first magazine, and at least one test element with a detection area, stored in a second magazine, the detection area containing reagents if necessary for use in detecting the analyte. The system also includes a housing, which encloses at least part of the first magazine and the second magazine and includes an opening for placement of a body part. At least one of the lancing elements and at least one of the test elements are located below the opening, and one of the magazines is located at least partly between the opening and the other magazine. The two magazines may at least partially overlap. The lancing element and the test element may be moved toward the opening so the body part resting on the opening can be lanced with the lancing element and the emerging bodily fluid can be collected using the test element at the same opening.

Claims

1. A system for analyzing a bodily fluid collected from a body part including:

a housing having an opening;

a first magazine located at least partially within the housing and including at least two lancing elements and a first recess disposed between the at least two lancing elements, the first magazine being moveable to align one of the at least two lancing elements with the opening to lance the body part; and

a second magazine located at least partially within the housing and at least partially overlapping the first magazine, the second magazine including at least two test elements and a second recess disposed between the at least two test elements, the second magazine being moveable to align one of the at least two test elements with the opening to receive body fluid from the lanced body part;

wherein the second recess exposes one of the at least two lancing elements to the opening when one of the at least two lancing elements is moved to align with the opening and the first recess exposes one of the at least two test elements to the opening when one of the at least two test elements is moved to align with the opening.

2. The system as recited in claim 1 wherein the one of the at least two lancing elements and the one of the at least two test elements are moved in succession toward the opening.

3. The system as recited in claim 1 further including a drive configured to incrementally move the first magazine.

4. The system as recited in claim 3 wherein the drive is configured to incrementally move the second magazine.

5. The system as recited in claim 1 further including a drive configured to move the one of the at least two lancing elements and the one of the at least two test elements toward the opening.

6. The system as recited in claim 5 wherein the drive is configured to move the other of the one of the at least two lancing elements and the one of the at least two test elements toward the opening.

7. The system as recited in claim 1 wherein at least one of the first magazine and the second magazine has a substantially circular profile.

8. The system as recited in claim 1 further including a resilient carrier wherein one of the lancing element and the test element is mounted on the resilient carrier in a manner allowing the one element to be deflected toward the opening.

9. The system as recited in claim 8 wherein the one element is mounted on the resilient carrier in a manner allowing the one element to be deflected away from the opening.

10. The system as recited in claim 1 wherein the lancing element is designed to draw fluid.

11. The system as recited in claim 10 wherein the one of the at least two lancing elements and the one of the at least two test elements are brought into contact with each other.

12. The system as recited in claim 1 further including a detection device.

13. The system as recited in claim 1 further including an evaluation device.

14. The system as recited in claim 1 further including a display.

15. The system as recited in claim 1 wherein the at least one lancing element includes a bend.

16. The system as recited in claim 1 wherein the one of the at least two lancing elements includes sterile protection.

17. The system as recited in claim 1 wherein the opening includes a press-down piece for placement of the body part on the opening.

18. The system as recited in claim 1 wherein the at least one recess exists before use of the system.

19. The system as recited in claim 1 wherein the at least one recess is defined without contact between the at least one lancing element and the at least one test element.

20. A system for analyzing a bodily fluid collected from a body part including:

a housing having an opening;

a first magazine located at least partially within the housing and including at least one lancing element and a first recess, the first magazine being moveable to align one of the at least one lancing element with the opening to position the lancing element for a puncturing procedure;

a protection element configured to maintain at least a portion of one of the at least one lancing element in a sterile condition until the puncturing procedure, during which the portion of the one of the at least one lancing element is exposed to the atmosphere; and

a second magazine located at least partially within the housing and at least partially overlapping the first magazine, the second magazine including at least one test element and a second recess, the second magazine being moveable to align one of the at least one test element with the opening;

wherein the lancing element extends through the second recess during the puncturing procedure and the one of the at least one test element receives body fluid from the lanced body part through the first recess.

21. The system as recited in claim 20 wherein the protection element is formed from a polymer and encloses a tip of the lancing element.

22. The system as recited in claim 20 wherein the protection element includes a foil that encloses the portion of the lancing element, the foil being punctured during the puncturing procedure.

23. A system for analyzing a bodily fluid collected from a body part including:

a housing having an opening;

a first magazine including a plurality of adjacent lancing elements;

a second magazine including a plurality of adjacent test elements;

wherein the first magazine is movable relative to the second magazine to align a lancing element of the first magazine between adjacent test elements of the second magazine to lance the body part through the opening and the second magazine is movable to align a test element of the second magazine between adjacent lancing elements of the first magazine to receive body fluid through the opening from the lanced body part.

24. A system for analyzing a bodily fluid collected from a body part including:

a housing having a housing opening;

a first magazine including a plurality of lancing elements separated from one another by a plurality of lancing element recesses;

a second magazine including a plurality of test elements separated from one another by a plurality of test element recesses;

wherein the first magazine is movable to align a lancing element of the plurality of lancing elements of the first magazine with an opening through a test element recess of the plurality of test element recesses of the second magazine to lance the body part and the second magazine is movable to align a test element of the plurality of test elements of the second magazine with an opening through a lancing element recess of the plurality of lancing element recesses of the first magazine to receive body fluid from the lanced body part.
