Abstract

The present invention relates to a system for the carrying out of a blood treatment, in particular a dialysis treatment, wherein the system has at least one blood treatment device, in particular a dialyzer, and at least one tank from which treatment fluid, in particular dialysis fluid, is removed during the carrying out of the blood treatment and/or into which consumed treatment fluid, in particular consumed dialysis fluid, is filled during the carrying out of the blood treatment, wherein the tank is an element of at least one mobile apparatus which can be connected to the blood treatment device such that at least one fluid connection can be established between the tank and the blood treatment device.

Claims

1. A system for the carrying out of a blood dialysis, the system comprising as separate components

a) at least one blood dialyzer (100) having no tank from which dialysis fluid (220) is removed during the blood dialysis and into which consumed dialysis fluid (230) is filled during the blood dialysis,

b) at least one multi-chamber bag (210) having flexible walls, at least one first chamber serving the reception of dialysis fluid (220), and at least one second chamber serving the reception of consumed dialysis fluid (230), wherein the first and second chambers are in communication with one another such that a volume increase of one chamber results in a corresponding volume reduction in the other chamber, from which bag dialysis fluid (220) is removed during the carrying out of the blood dialysis, and into which consumed dialysis fluid (230) is filled during the carrying out of the blood dialysis, wherein the multi-chamber bag is mechanically supported by a mobile apparatus (200) which is to be releasably connected to the blood dialyzer (100) such that at least one fluid connection is to be established between the bag (210) and the blood dialyzer (100) and a data connection is established such that data from the mobile apparatus relating to dialysis fluid in the bag are read out by the dialyzer, and

c) at least one stationary filling unit (300) which is adapted to be releasably connected to the bag to fill the bag with dialysis fluid,

wherein the mobile apparatus is adapted for moving between, when not connected to either of, the blood dialyzer and the filling unit.

2. A system in accordance with claim 1, further comprising at least one fluid connection between the bag (210) and the blood dialyzer (100) provided automatically or on demand after the moving of the mobile apparatus (200) into and the blood dialyzer (100) into a predefined positions.

3. A system in accordance with claim 1, characterized in that the blood dialyzer (100) has a mount for reception of the mobile apparatus (200).

4. A system in accordance with claim 1, characterized in that the mobile apparatus (200) has casters providing easy movability.

5. A system in accordance with claim 1, characterized in that the mobile apparatus (200) is gas-tight.

6. A system in accordance with claim 1, characterized in that the mobile apparatus (200) has means for the leading off consumed dialysis fluid (230) from the bag into an outflow or into another reception unit.

7. A system in accordance with claim 1, characterized in that the filling unit (300) has means by means of which the dialysis fluid (220) is to be manufactured from one or more concentrates and water.

8. A system in accordance with claim 1, characterized in that the filling unit (300) is in communication with an RO water supply unit or has such a unit.

9. A method comprising the steps of supplying a blood dialyzer (100) with a dialysis fluid (220) which is removed from a multi-chamber bag (210) during carrying out of a blood dialysis, characterized in that the multi-chamber bag has flexible walls, at least one first chamber serving the reception of dialysis fluid (220), and at least one second chamber serving the reception of consumed dialysis fluid (230), wherein the first and second chambers are in communication with one another such that a volume increase of one chamber results in a corresponding volume reduction in the other chamber, wherein the bag is mechanically supported by a mobile apparatus (200) which is connected to the blood dialyzer (100) for the carrying out of the blood dialysis such that a fluid connection is present between the bag (210) and the blood dialyzer (100) and a data connection is established such that data from the mobile apparatus relating to dialysis fluid in the bag are read out by the dialyzer, and, after carrying out the blood dialysis, releasably connecting the mobile apparatus to a filling unit, to establish a fluid connection between the bag and the filling unit, and supplying the bag with blood dialysis fluid from the filling unit (300).

10. A method in accordance with claim 9, further comprising the step of supplying consumed dialysis fluid (230) to the bag (210) from the blood dialyzer through the fluid connection.

11. A method in accordance with claim 9, further comprising the steps of moving the mobile apparatus (200) to the filling unit (300) followed by filling the bag (210) with dialysis fluid (220) from the filling unit.

12. A method in accordance with claim 10, characterized in that the method is carried out such that dialysis fluid (220) is supplied from the at least one bag (210) and consumed dialysis fluid (230) is supplied to the at least one bag (210) simultaneously or offset in time.

13. A method in accordance with claim 11, characterized in that, after the movement of the mobile apparatus (200) to the blood dialyzer (100) into a preset position, at least one fluid connection is established automatically or on demand between the bag (210) and the blood dialyzer (100).

14. A method in accordance with claim 11, characterized in that, after the movement of the mobile apparatus (200) to the blood dialyzer (100) into a preset position, the data connection is established automatically or on demand between the mobile apparatus (200) and the blood dialyzer (100).

15. A method in accordance with claim 11, characterized in that the mobile apparatus (200) is moved to the filling unit (300) or to a separate emptying unit and consumed dialysis fluid (230) is disposed of from the bag (210) by the filling unit (300) or by the separate emptying unit.
