Abstract

The present invention relates to a valve device comprising an elastic valve insert and a reception means for the valve insert. It further relates to a valve insert, an external functional means and a treatment apparatus, as well as a manufacturing method and methods in which the valve device of the invention may be employed.

First claim

What is claimed is:

1. A valve device comprising:
at least one valve insert which is elastic in at least one portion thereof; and
at least one reception means for receiving the valve insert,
wherein the valve insert is configured such that due to its elasticity it may be switched between at least three different valve states upon an impression of path and/or an application of force, and
wherein the valve states are selected from the group consisting of an opened functional state of the valve, a check valve state, a control or regulation valve state and a closed valve state.

2. The valve device according to claim 1 , wherein one of the at least three different valve states is the opened functional state of the valve.

3. The valve device according claim 1 , wherein one of the at least three different valve states is the check valve state.

4. The valve device according to claim 1 , wherein one of the at least three different valve states is the control or regulation valve state.

5. The valve device according to claim 1 , wherein one of the at least three different valve states is the closed valve state.

6. The valve device according to claim 1 , wherein the valve insert comprises an elastomer material at least in a portion thereof.

7. The valve device according to claim 1 , wherein the valve insert comprises impressions at least in a portion thereof.

8. The valve device according to claim 1 , wherein the valve insert comprises at least one first sealing means provided and adapted for being pressed in at least one portion thereof by form closure and/or frictionally with at least one portion of a second sealing means of the reception means.

9. The valve device according to claim 8 , wherein the first sealing means is pressable with the second sealing means by impression of path and/or transmission of force to the valve insert.

10. The valve device according to claim 8 , wherein a force acting on the valve insert is a pressing force introduced by installation of the valve device into a treatment apparatus.

11. The valve device according to claim 9 , wherein the impression of path on the valve insert is a displacement introduced by installation of the valve device into a treatment apparatus.

12. The valve device according to claim 10 , wherein the pressing force is transmitted by a transmission member of the treatment apparatus.

13. The valve device according to claim 11 , wherein the displacement is transmitted by a transmission member of the treatment apparatus.

14. The valve device according to claim 1 , wherein the valve insert comprises at least one guiding means for introducing the valve insert into the reception means.

15. The valve device according to claim 1 , wherein the valve insert comprises at least one elastic bending ring region.

16. The valve device according to claim 1 , wherein the valve device is provided with a cover means at least on one upper side thereof.

17. The valve device according to claim 1 , wherein the valve insert is switchable across the cover means by a force and/or an impression of path transmitted by a treatment apparatus.

18. An external functional means comprising at least one valve device according to claim 1 .

19. The external functional means according to claim 18 , wherein the external functional means is configured as a blood treatment cassette having blood-conducting passages for extracorporeal blood treatment, wherein substituate and/or one or several drugs are introducable into the blood-conducting passages via the valve device.

20. A method of controlling or regulating a passage of fluid, including the step of:
controlling the valve device according to claim 1 to control or regulate the passage of the fluid.

21. The method according to claim 20 , further including the step of:
applying a defined force and/or a defined impression of path to an upper side of the valve insert for the purpose of switching the valve insert.

22. The method according to claim 21 , wherein the force and/or the impression of path is applied to the upper side of the valve insert by a transmission member.

23. The method according to claim 21 , wherein the force and/or the impression of path is applied to the valve insert across a cover means.

24. The method according to claim 21 , wherein the force is a pressing force or the impression of path is a displacement, and the force and/or the impression of path is introduced by installation of the valve device or of an external functional means comprising the valve device into a treatment apparatus.

25. The method according to claim 21 , wherein the force and/or the displacement is a force and/or displacement resulting from the flow of fluids passing through the valve device.

26. A treatment apparatus comprising at least one valve device according to claim 1 and/or an external functional means comprising at least one valve device according to claim 1 .

27. The treatment apparatus according to claim 26 , wherein the treatment apparatus is configured as a blood treatment apparatus.
