Abstract

A cartridge, an analysis system and a method for analyzing, in particular, a biological sample, wherein a first group having one or more valves and a second group having one or more valves can be or are actuated from different sides of the cartridge.

First claim

What is claimed is:

1. An analysis system for testing a biological sample, comprising:
a cartridge for receiving a sample, and
an analysis device for testing the sample,
the cartridge comprising a fluid system having a plurality of channels formed in said cartridge and a plurality of valves for controlling a flow of sample or fluid through the fluid system provided in said cartridge, and
the analysis device being adapted to at least partially receive the cartridge and comprising a plurality of actuation apparatus for actuating the plurality of valves,
wherein at least one of the plurality of actuation apparatus is designed to open the plurality of valves at the same time upon actuation,
wherein the at least one of the plurality of actuation apparatus comprises a drive, a connection element and a plurality of actuation elements arranged next to one another, wherein the connection element connects the plurality of actuation elements to the drive, and
wherein at least one of the plurality of actuation apparatus is designed to close an associated valve of the plurality of valves upon actuation.

2. The analysis system according to claim 1 , wherein the cartridge is adapted to be arranged between at least two of the plurality of actuation apparatus.

3. The analysis system according to claim 1 , wherein the cartridge comprises an at least substantially planar or flat support.

4. The analysis system according to claim 3 , wherein at least one of the channels and the valves are formed by depressions in the support.

5. The analysis system according to claim 1 , wherein the plurality of valves comprises a first group having at least one valve and a second group having at least one valve, the at least one valve of the first group being actuatable from a different side of the cartridge from the at least one valve of the second group.

6. The analysis system according to claim 5 , wherein the valves of the first group can be opened irreversibly or closed irreversibly.

7. The analysis system according to claim 6 , wherein at least one of the plurality of actuation apparatuses is able to actuate a plurality of valves from the first group simultaneously.

8. An analysis system according to claim 1 , wherein the plurality of valves comprises a first group having at least two valves and a second group having at least two valves, wherein the valves of the first group are opened by actuation and the valves of the second group are closed by actuation, wherein one valve of the first group is arranged upstream and one valve of the first group is arranged downstream of a storage cavity in the cartridge, so that the storage cavity of the cartridge is closed in a storage-stable manner by the two valves of the first group when said valves are unactuated, and wherein a valve of the second group is arranged immediately next to each of said upstream and downstream valves of the first group.

9. The analysis system according to claim 1 , wherein the cartridge comprises a through-hole and at least one of the valves is actuatable via the through hole.

10. The analysis system according to claim 1 wherein the valves comprise a wall or film that is flexible or elastically deformable at least in part, the valves being actuated by the wall or film being elastically deformed.

11. The analysis system according to claim 1 , wherein the actuation apparatuses each comprise a drive.

12. The analysis system according to claim 1 , wherein the actuation apparatuses each comprise at least one actuation element.

13. The analysis system according to claim 1 , wherein the cartridge comprises a plurality of through holes and wherein each valve of the plurality of valves openable upon actuation comprises a deflection element that can be raised by inserting the actuation elements into the through holes such that the valves are opened.

14. A method for testing a biological sample, comprising:
receiving a sample in a cartridge and
at least partially receiving the cartridge containing the sample in an analysis device,
controlling a flow of the sample in the cartridge by means of a plurality of mechanically actuated valves, and
opening a plurality of the valves at the same time by means of a common actuation apparatus.

15. The method according to claim 14 , further comprising: closing a plurality of the valves by actuation.

16. The method according to claim 14 , wherein the common actuation apparatus passes through the cartridge at least in part.

17. A cartridge for testing a biological sample, comprising:
a fluid system having a plurality of channels and a plurality of valves for controlling a the flow of at least one sample or fluid through the fluid system,
a storage cavity for a reagent,
wherein the valves comprise a first group having a plurality of valves and a second group having a plurality of valves,
wherein the valves of the first group are openable by actuation and the valves of the second group are closable by actuation,
wherein one valve of the first group is arranged upstream of the storage cavity and one valve of the first group is arranged downstream of the storage cavity, so that the storage cavity is closed in a storage-stable manner by the two valves of the first group when said valves are unactuated, and
wherein a valve of the second group is arranged immediately next to each of said upstream and downstream valves of the first group.

18. The cartridge according to claim 17 , wherein the valves comprise a wall or film that is flexible or elastically deformable at least in part, the valves being actuated by the wall or film being elastically deformed.

19. The cartridge according to claim 17 , wherein the cartridge comprises an at least substantially planar or flat support.

20. The cartridge according to claim 19 , wherein at least one of the channels, the valves of the first group or the valves of the second group are formed by depressions in the support.

21. The cartridge according to claim 17 , wherein the cartridge comprises a plurality of through-holes and the valves of the first group are actuatable via the through holes.
