Abstract

A combination includes a container having a connecting portion, and a fluid preparation device, in particular a dialysis machine. The fluid preparation device is configured for mounting and connecting the connecting portion of the container. The fluid preparation device includes at least one line in fluid communication with an interior of the container in the connected position of the container. The container is filled with a first medium, and includes a reservoir containing a second medium. The fluid preparation device includes a rod-shaped element for opening the reservoir so that the first medium and the second medium are mixed with each other.

First claim

What is claimed is:

1. A combination comprising:
a container having a connecting portion; and
a fluid preparation device configured for mounting and connecting the connecting portion of the container,
the fluid preparation device including at least one line in fluid communication with an interior of the container in a connected position of the container,
the container being filled with a first medium, and
including a reservoir containing a second medium, with the reservoir including a housing, and a piston which is movable relative to the housing in a first direction,
the fluid preparation device including an element for opening the reservoir so that the first medium and the second medium are mixed with each other, and a lid, with the lid including the element for opening the reservoir, and
with the element for opening the reservoir being rod-shaped and pivotably fixed to the lid, to interact with the piston is essentially the first direction, so as to open the reservoir.

2. The combination according to claim 1 , wherein the at least one line includes a flushing fluid line for feeding a fluid into the interior of the container, and a prepared fluid line for guiding a prepared fluid out of the interior of the container, and wherein the flushing fluid line and the prepared fluid line are formed by a same line or by different lines.

3. The combination of claim 1 , wherein the fluid preparation device includes a mounting connector part configured for mounting and connecting the connecting portion of the container, wherein the mounting connector part at least in part includes the at least one line, and wherein the mounting connector part includes at least one mounting element configured to mate with at least one mounting element of the connecting portion of the container, so that the mounting element of the mounting connector part is in fluid communication with the mounting element of the connecting portion of the container.

4. The combination of claim 1 , wherein the lid is turnable around a joint or axis from a first position to a second position, and wherein in the first position of the lid the reservoir is still closed and in the second position of the lid the reservoir is opened.

5. The combination of claim 1 , wherein the fluid preparation device includes at least one mechanical stop adapted to restrict a range of movement of the element for opening the reservoir.

6. The combination of claim 1 , wherein the fluid preparation device includes at least one spring which interacts with the element for opening the reservoir.

7. The combination of claim 1 , further comprising at least one of
one or more sensors for sensing a position of the element for opening the reservoir or for sensing a position of a support to which the element for opening the reservoir is mounted, and
one or more fixing elements for fixing the element for opening the reservoir or for fixing the support to which the element for opening the reservoir is mounted.

8. The combination according to claim 1 , wherein the fluid preparation device is a dialysis machine.

9. The combination according to claim 1 , wherein the housing is cylindrical.

10. A method of preparing a composition for preparing a dialysis fluid, the method comprising the following steps:
a) with a container having a connecting portion, and a fluid preparation device configured for mounting and connecting the connecting portion of the container, the fluid preparation device including at least one line in fluid communication with an interior of the container in a connected position of the container, the container being filled with a first medium, and including a reservoir containing a second medium, with the reservoir including a housing, and a piston which is movable relative to the housing in a first direction, the fluid preparation device having an element for opening the reservoir so that the first medium and the second medium are mixed with each other, and a pivotable lid, with the lid including the element for opening the reservoir, and with the element for opening the reservoir being rod-shaped and pivotably fixed to the lid,
putting the container with the connection portion thereof into the fluid preparation device;

b) pivotably moving the lid such that the element for opening the reservoir movably actuates the piston in essentially the first direction; and
c) by the actuating of the piston, opening the reservoir so as to mix the first medium and the second medium.
