Abstract

A diagnostic system has a diagnostic module with an integrated lancet system and a magazine module separate from the diagnostic module. The diagnostic device also has a connecting device that is used for tensioning the lancet system.

Claims

1. A diagnostic system for determining substance concentrations in liquid samples, the system comprising:

a diagnostic module with a lancet system integrated into the diagnostic module;

a magazine module which is separate from the diagnostic module and is used to store test strips; and

a connecting device for connecting the magazine module to the diagnostic module.

2. The system of claim 1, wherein the connecting device has a tensioning device for tensioning the lancet system such that upon connection of the magazine module to the diagnostic module, the lancet system is tensioned.

3. The system of claim 2, where the connecting device has a tensioning device for tensioning the lancet system such that upon connection of the magazine module to the diagnostic module, the lancet system is tensioned.

4. The system of claim 2, wherein the tensioning device has a tensioning slide connected to a spring system.

5. The system of claim 1, wherein the connecting device has an actuating device for operating the magazine module such that upon connection of the magazine module to the diagnostic module, at least one test strip is output.

6. The system of claim 5, wherein the connecting device is connected to an actuating device for operating the magazine module such that upon connection of the magazine module to the diagnostic module, at least one test strip is output.

7. The system of claim 1, further comprising a data exchange device for exchange of batch information on the test strips between the magazine module and the diagnostic module.

8. The system of claim 7, wherein the data exchange device has a transponder arranged in the magazine module, and a transponder reading unit arranged in the diagnostic module.

9. The system of claim 7, wherein the data exchange device has a data memory arranged in the magazine module.

10. The system of claim 7, wherein the data exchange device has at least one electrical contact arranged in the connecting device.

11. The system of claim 1, wherein the connecting device has a push-in connection.

12. The system of claim 11, wherein the push-in connection has a dovetail guide.

13. The system of claim 1, wherein the diagnostic module has a display and/or a computer system.

14. A diagnostic system for determining substance concentrations in liquid samples, the system comprising:

a diagnostic module with a lancet system integrated into the diagnostic module;

a magazine module which is separate from the diagnostic module and is used to store test strips;

a connecting device for connecting the magazine module to the diagnostic module;

a data exchange device for exchange of batch information on the test strips between the magazine module and the diagnostic module; and

a display for dislaying the substance concentration

15. The system of claim 14, wherein the connecting device has a tensioning device for tensioning the lancet system such that upon connection of the magazine module to the diagnostic module, the lancet system is tensioned.

16. The system of claim 15, wherein the connecting device is connected to a tensioning device for tensioning the lancet system such that upon connection of the magazine module to the diagnostic module, the lancet system is tensioned.

17. The system of claim 15, wherein the tensioning device has a tensioning slide connected to a spring system.

18. The system of claim 14, wherein the connecting device has an actuating device for operating the magazine module such that upon connection of the magazine module to the diagnostic module, at least one test strip is output.

19. The system of claim 18, wherein the connecting device is connected to an actuating for operating the magazine module such that upon connection of the magazine module to the diagnostic module, at least one test strip is output.

20. The system of claim 14, wherein the data exchange device has a transponder arranged in the magazine module, and a transponder reading unit arranged in the diagnostic module.

21. The system of claim 14, wherein the data exchange device has a data memory arranged in the magazine module.

22. The system of claim 14, wherein the data exchange device has at least one electrical contact arranged in the connecting device.

23. The system of claim 14, wherein the connecting device has a push-in connection.

24. The system of claim 23, wherein the push-in connection has a dovetail guide.

25. A diagnostic system for determining substance concentrations in liquid samples, the system comprising:

a diagnostic module with a lancet system integrated into the diagnostic module;

a magazine module which is separate from the diagnostic module and is used to store test strips; and

wherein the diagnostic system comprises the following operating elements;

an actuating device for operating the magazine module;

a trigger device for triggering the lancet system; and

an operating system for operating the diagnostic module.

26. The system of claim 25, wherein the system has substantially vertical grip portion and a substantially horizontal operating surface.

27. The system of claim 26, wherein the operating surface has at least one operating element.

28. The system of claim 25, wherein at least three operating elements can be operated by one hand when the magazine module is connected to the diagnostic module.

29. The system of claim 25, wherein the magazine module has at least one measurement electrode and, when the magazine module is connected to the diagnostic module, the diagnostic module is connectable to at least one test strip via the at least one measurement electrode.

30. The system of claim 25, wherein the magazine module has a stack magazine for test strips.

31. The system of claim 25, wherein the magazine module has an actuating device for output of test strips.

32. The system of claim 31, wherein the actuating device comprises:

an actuating button, a push rod and a push element for moving a test strip, the push element having at least a first pushing edge and a second edge for holding a test strip.

33. A diagnostic system for determining substance concentrations in liquid samples, the system comprising:

a diagnostic module with a lancet system integrated into the diagnostic module;

a magazine module which is separate from the diagnostic module and is used to store test strips; and

a connecting device for connecting the magazine module to the diagnostic module;

wherein, the system has a substantially vertical grip portion and a substantially horizontal operating surface.

34. A method for operating a diagnostic system for determining substance concentration in a liquid, the method comprising:
