The invention is described below in more detail using embodiments shown in the
following figures as follows:
Figures 1 ¨ 3: sectional views of the reservoir and of the mounting connector
as well as of the lid in different positions of the lid,
Figure 4: a further cross-sectional view of the mounting connector part and
the lid in a closed position without reservoir,
Figure 5: a further cross-sectional view of the lid and of the means for

and the lid and

Figure 1 shows the lid 60 in a first, opened position. In this position, the
opening the reservoir 56 which consists of a rod, made for example of metal,
cover 56' which is made for example from plastics, is not in contact with the
As shown in figure 1 one end of the rod 56 is provided with said cover 56'.
The oth-
er end of the rod 56 is pivotally connected via a joint or axis 57 to the lid
Accordingly, the rod 56 is not fixedly mounted to the lid 60 but is moveable
As further shown in figure 1 the fluid preparation device 50 not only
lid 60 but also a mounting connector part 58 which is adapted to be connected
container. Reference is made to figure 7 and the corresponding explanations
which are part of this invention as well.
The container which is not shown in figures 1 ¨ 6 is connected with or
arranged be-
low the reservoir 100 which comprises a housing 102 as well as a piston 104
is moveable relative to the housing 102. The reservoir is filled with a second
um which is different to the medium contained in the container.
In accordance with a preferred embodiment the reservoir 100 is filled with a
such as an acid.
As shown in figure 1 the piston 104 has a slanted lower edge, which provides
cutting tool for opening the button B of the housing 102 of the reservoir 100.
The movement of the lid 60 from the position shown in figure 1 around axis 60'
the position shown in figure 2 results in a contact between the rod 56 or the
56' with the upper portion of the piston 104 which has an indentation as shown
the figure. This situation is shown in figure 2. In this position of the lid
60 the reser-
voir 100 is still closed so that its content is not mixed with the content of
tainer. The rod 56 is accommodated in said indentation.
If the lid 60 is pressed downwards starting from figure 2 to the position
figure 3 the rod 56 moves the piston 104 in a downward direction relative to
housing 102 and the lower slanted edge of the piston 104 opens the bolt B of
reservoir 100 so that the second medium such as an acid is emptied from the
ervoir into the container. This position is shown in figure 3.
As outlined above the container may comprise electrolytes, preferably in a
form. In addition the container may comprise preferably solid osmotic agents
The reservoir 100 preferably contains an acid, preferably a solid acid, which
mixed with the content of the container upon opening of the reservoir.
As shown in figure 3 the downward movement of the lid inevitably results in an
opening of the reservoir so that the likelihood that the reservoir is closed
the lid is in its closed downward position is minimized.
Figure 4 shows a position in which no container is located in the mounting
or part of the fluid preparation device. In this case the lid is completely
the rod may be accommodated in a space of the mounting connector part which is
designated with reference numeral S.
As outlined above and as shown in more detail in figure 5 the rod 56 is not
mounted at the lid but is moveably relative to the lid, e. g. via axis 57. The
figure 5 designate mechanical stops 300 which are formed by abutments which
the pivoting movement of the rod 56 relative to the axis 57.
Furthermore, reference numeral 400 designates a spring which interacts with
rod so that a force is posed into the rod preferably in the direction of the
If the lid 60 is moved from the position shown in figure 1 to the position
figure 3 the lid performs a rotational movement around axis 60'. In case that
56 would be fixedly mounted to the lid 60 the rod 56 would exactly make the
kind of movement as the lid 60. This might have the effect that the rod 56
moved in a lateral direction after contacting the piston in figure 2 which
to a tilting or any other dysfunction of the opening of the reservoir.
Due to the flexible mounting of the rod 56 my means of a joint, hinge, axis,
smooth and steady movement of the piston is realized.
Figure 6 shows the embodiment of figure 5 together with the reservoir 100 in
position of the rod 56 which corresponds to the position shown in figure 2.
The use of at least one spring and at least one mechanical stop ensures that
rod is positioned on the piston in the correct position and orientation.
As further outlined above one or more sensors 200, such as Hall sensors, may
provided for detecting the position of the lid and/or of the means for opening
reservoir, such as the rod. These sensors may be connected with a controller
is adapted so as to allow the start of the treatment depending on the signal
sensor. If the sensor detects a position of the lid and/or of the means for
the reservoir which is not the correct one, this controller may inhibit the
treatment because it is assumed that the reservoir has not been opened.
Furthermore, the connecting portion of the container or any other part of the
tainer such as a reservoir may have identification means for identification of
container and in particular of the content thereof. Reading means may be
which read out those identification means and allow start of the treatment
correct identification has been verified.
Furthermore there may be provided fixing means for fixing the lid in one or
predetermined positions to secure the correct operation of the device.
Furthermore there may be one or more channels for ventilating the interior of
container when the fluid is drained from the container. Those channels may be
vided in the mounting connector part and/or in the connecting portion of the
Referring to the embodiment of figure 7, the fresh fluid may be guided into
tainer by line 52, the mounting means 34b and 58b and preferably by means of a
tube within the container according the embodiment shown in DE 10 2011 106 248
A1 and the prepared solution may be drained from the container by the same
Alternatively the fresh fluid line and the prepared fluid line may be
