Breastpump set
Technical field
The invention relates to a breastpump set, a
breastshield and a connecting tube according to the
preambles of patent claims 1, 8, 15 and 17.
Prior art
Breastpumps for expressing human breastmilk are well
known. There are basically two different types. The
first are operated manually, i.e. the vacuum needed for
milk expression is generated by manual actuation of the
suction pump. In the second type, the suction pump is
driven electrically, in which case the suction pump can
be connected to the mains electricity and/or can be
operated by a battery or another energy storage means.
To ensure that the function of the breastpump can be
adapted optimally to the needs of the mother, some of
the pumps allow the mother to regulate the vacuum. For
example, US 2004/0024351 and US-A-4,813,932 disclose
manually actuated breastpumps that have adjustable
valves. In the case of manually operated pumps, the
suction capacity of the pump itself is additionally
regulated by means of the mother increasing or
decreasing the pump strength to meet her requirements.
In electrically driven pumps too, it is customary for
air release means to be arranged on the breastshield or
on the connecting line to the suction pump. This is the
case in US 6,706,012 and US 6,042,560, for example.
US 6,110,140 proposes a manually or electrically
operated breastpump which, in the area of the
breastshield, has a vacuum regulator for regulating the
vacuum generated by the suction pump. This regulator

WO 2006/079229 - 2 - PCT/CH2005/000730
can be actuated during use of the breastpump, such that
the vacuum prevailing in the breastshield can be
adjusted.
In addition to the solutions described above, which all
allow the vacuum generated by the suction pump to be
modified in the area of the breastshield, some
electrically driven breastpumps also afford the
possibility of modifying the vacuum or the suction
rhythm on the pump unit itself. This is done via
corresponding actuation switches or buttons that are
arranged on the suction pump. However, to be able to
actuate these buttons, the mother has to have one hand
free. This is not possible, however, especially if the
mother wishes to express milk from both breasts
simultaneously.
Summary of the invention
It is therefore an object of the invention to allow the
mother to operate the suction pump as easily as
possible.
This object is achieved by a breastpump set, a
breastshield and a connecting tube with the features of
patent claims 1, 8, 15 and 17.
The breastpump set according to the invention for
expressing human breastmilk comprises a breastshield to
be placed on a mother's breast, a milk collection
container, and an electrically driven suction pump, in
which the breastshield has an operating means for
operating the suction pump.
By virtue of the breastpump set according to the
invention, the mother is therefore able to influence
the function of the suction pump without having to be
able to reach the latter. The mother can use the same

WO 2006/079229 - 3 - PCT/CH2005/000730
hand with which she is holding the breastshield to her
breast. She can therefore express milk from both
breasts simultaneously or use the free hand for
something else.
The operating means is preferably arranged nearby on
the breastshield funnel.
In preferred embodiments, the operating means is
arranged facing upward or sideways in the position of
use of the breastshield, to ensure that said operating
means is easily accessible. However, depending on the
shape and configuration of the breastshield, other
locations are also possible for the placement of the
operating means, preference being given to locations
that are easily accessible and correspond to the
natural position adopted by the mother as she expresses
milk. Moreover, the operating means can also be
arranged on a part of the breastshield that can be
folded open, plugged on or removed, with the result
that the operating means is exposed only when the
mother wishes to use it.
Depending on the embodiment, the suction pump can be
switched on and off by the operating means. In
addition, or as an alternative to this, its pumping
capacity can also be modified according to the
requirements of the mother.
If a suction pump is used that can operate two
breastshields simultaneously, then, depending on the
design of the suction pump, only one of the
breastshields is provided with the operating means, and
the suction pump operates both breastshields in
accordance with the same operating signals. If the
suction pump is able to operate the two breastshields
with different suction rhythms or pumping capacities,

WO 2006/079229 - 4 - PCT/CH2005/000730
both breastshields can be provided with an operating
means in order to individually adjust the suction pump.
The signals can be sent from the operating means to the
suction pump mechanically, by wireless transmission, or
via corresponding cable connections. In the case of
wireless transmission, it is possible, for example, to
use a radio antenna, an infrared interface, a Bluetooth
signal transmission, or another of the known types of
wireless transmission. The cable connection is
preferably effected via an electrical signal in a known
manner.
Instead of an operating means, it is also possible to
use a voice recognition means, which then transmits a
control signal to the suction pump. This voice
recognition means can be arranged in the area of the
breastshield, directly on the suction pump, or on an
additional external unit connected to the suction pump.
The breastshield preferably comprises a main body
formed by one piece, in which the operating means and
any connecting cables for signal transmission are
arranged. To keep the costs of such breastshields as
low as possible, however, the main body can also be
formed of several pieces, in which case, for example, a
breastshield funnel is designed as a disposable product
and at least the part with the operating means is able
to be reused.
Further advantageous embodiments are set forth in the
dependent patent claims.

The subject matter of the invention is explained below
on the basis of preferred illustrative embodiments
depicted in the attached drawings, in which:

Embodiments of the invention
Figure 1 shows a first embodiment of the breastpump set
according to the invention. It basically comprises at
least one breastshield 1, a milk collection container 2
that can be secured on the breastshield 1, and an
electrically driven suction pump 4, which is connected
to the breastshield 1 via a suction line 3.
The breastshield 1 has a breastshield funnel 10, which
is placed on the mother's breast during use. The funnel
10 merges into a breastshield neck 11, which is
adjoined by first and second breastshield coupling
parts 12, 13. The first breastshield coupling part 12
has an inner thread that can be screwed onto an outer
thread of the milk collection container 2, here a
baby's bottle. The second breastshield coupling part 13
has an attachment (not visible in the figure) into
which the suction line 3, here a tube, can be fitted.

WO 2006/079229 - 6 - PCT/CH2005/000730
The other end of the tube can be fitted in the suction
pump 4. The vacuum or underpressure generated in the
suction pump is applied by way of this tube to the
breastshield, such that the milk is expressed from the
mother's breast and can be collected in the milk
collection container 2.
Figure 1 shows the customary position of use. The first
coupling part 12 is directed downward, and the second
coupling part 13 is directed rearward or obliquely
downward, in any case away from the mother's breast.
The suction pump 4 can be one of the known motor-driven
suction pumps. It preferably has actuating and control
keys or buttons 40 and a display 41. In the
illustrative embodiment shown here, it is designed as
an independent, portable unit.
According to the invention, the breastshield 1 now has
an operating means, here in the form of an operating
panel 5, via which the suction pump 4 can be operated.
This operation is preferably performed independently of
the setting of the actuating and control keys or
buttons 40 arranged on the suction pump 4.
The operation can involve the switching on and off of
the suction pump 4, but also the adjustment of the
suction rhythm, the suction curve, the suction
capacity, the intervals between individual cycles, etc.
The operating panel 5 is preferably arranged in the
area of the breastshield funnel 10. In the example
shown here, it is secured on or fitted into the
breastshield neck 11 adjacent to the funnel 10. It is
preferably directed upward in the position of use shown
here, such that it can be reached by the same hand with
which the mother is holding the breastshield 1 to her
breast. However, the operating panel 5 can also be

WO 2006/079229 - 7 - PCT/CH2005/000730
arranged on the side or bottom of the neck 11, for
example.
The operating panel 5 is secured on or in the
breastshield 1 by known means. The main body of the
breastshield 1 itself is usually made of plastic and is
designed in one piece or several pieces. The operating
panel 5 can, for example, be cast into this main body
or affixed to it by adhesion. In the latter case, the
main body can have a suitable recess in which the
operating panel 5 can be fitted, such that the latter
does not protrude too far and is thus protected. Any
cables for signal transmission can be connected in the
same way to the breastshield 1 or integrated in it.
The operating panel 5 can comprise switches, push keys,
sensor keys, rotatable knobs, slides or other known
means, such that the mother can transmit the desired
control signals to the suction pump 4 and to the
control system 42 arranged therein.
In the illustrative embodiment shown here, the signals
are transmitted from the breastshield 1 to the suction
pump 4 via a signal line 6. This line can run separate
from the suction line 3 and can also be connected via
other attachment points to the breastshield 1 and to
the suction pump 4. However, a connecting tube is
preferably used that contains both the suction line 3
and also the signal line 6. Depending on the design,
there can be more than one suction line 3 and more than
one signal line 6. The at least two lines 3, 6 are
preferably connected to one another along their entire
length. For example, they are co-extruded or, after
being produced separately, are encapsulated together.
At both ends, they have plugs that can be fitted into
corresponding sockets in the breastshield 1 and the
suction pump 4.

WO 2006/079229 - 8 - PCT/CH2005/000730
If two breastshields 1 are attached to the same suction
pump 4, there are of course two connecting tubes with
suction lines 3, in which case both tubes or only one
of them can additionally have a signal line 6.
An alternative embodiment is shown in Figure 2.
Identical parts have been provided with the same
reference numbers. Here, the signals are not sent from
the breastshield 1 to the suction pump 4 via a line,
but instead by wireless transmission, preferably by
radio. An antenna 50 is shown here as one
representative of all the possibilities of wireless
transmission, and it will be noted that the presently
available antennas can generally be integrated into the
breast shield 1 in a planar manner.
In the illustrative embodiments according to Figures 3
and 4, the milk collection container 2 is not shown. It
is, however, screwed onto the first coupling part 12 in
the known manner. In contrast to the above embodiments,
the suction pump is in this case a suction pump unit 4'
that is secured directly on the second coupling part 13
of the breastshield 1. Such suction pumps usually have
a battery or another energy storage means, which is
likewise arranged in this unit 4' . The suction pump
unit 4' is secured on the breastshield 1 in a known
manner, for example by a screw connection, clamping
means, or another form-fit or force-fit securing means.
To ensure that it can be easily reached by the fingers,
the operating panel 5 of the pump 4' is not arranged on
the unit itself, but instead on the breastshield 1,
preferably in the area of the funnel 10 as before. In
this case too, the neck 11 of the shield 1 has proven
to be a particularly suitable location.

WO 2006/079229 - 9 - PCT/CH2005/000730
In Figure 3, the operating panel 5 has at least one,
preferably several keys 51, and in Figure 4 it has at
least one rotatable knob 52.
In the embodiment according to Figure 5, the operating
panel 5 is protected by a flap 53 that can be folded
open. In Figure 6, the operating panel 5 can be plugged
on, in which case the breastshield neck 11 has a
corresponding recess 100 with pins that engage in
securing holes of the panel 5.
The signals can again be sent to the suction pump unit
4' via signal lines or by wireless transmission. If
signal lines are used, the contact or connection
between the line sections routed in the breastshield 1
and in the suction pump unit 4' is preferably made
automatically when the pump 4' is coupled to the shield
1.
The breastpump set according to the invention thus
permits easy operation of the suction pump and
eliminates the need for the mother to have onehand
free for handling it.
