Suction hood for breast milk suction device. - Sugkopp för moders-mjölks suganordning.

The present invention relates to a suction hood for a breast milk suction device, the suction hood having a suction piece, a connection socket for a vacuum line and a connection socket for a collection container.

Such suction hoods are known, e.g. from DE-A-1,067,932, and form an integral part of breast milk suction devices, which devices naturally include a suction pump which, as usual, develops an intermittent vacuum. In addition to the purely hygienic requirements of the device, there are also technical problems in the known solutions, which have been solved, at least in part, unsatisfactorily.

Thus, it repeatedly happens that the milk gets into the vacuum line and even up to the pump. This is counteracted by placing so-called safety volumes between the suction hood and the pump, which, however, involves very high technical costs. In addition, new problems arise, e.g. with respect to the system or the actual operation, because there may be variations in the intensity of the vacuum.

It is now an object of the present invention to provide a suction hood which can largely eliminate the deficiencies which occur.

The suction hood according to the invention is characterized in that the collecting chamber, with its valves arranged therein, is releasably connected to the remaining part of the suction piece.

Thanks to the collection chamber with a valve, it is also possible to pump into a collection container in the form of a plastic bag, since the vacuum no longer affects the collection container.

2 72268 In addition, overflow can be avoided because the valve opens in time and the pumped milk flows into the collecting vessel.

The structure according to the invention solves the sealing problems and allows the use of a small pump, since the vacuum volume required for intermittent operation can be substantially smaller compared to known solutions (no vacuum is required for the volume of the collecting vessel due to the valve or for the safety volume because this space is omitted).

One very important advantage is that a constant vacuum (vacuum) is created, because there are no longer any variable volumes in the system (previously the volume of the collecting vessel changed with increasing filling).

Finally, it should be noted that the suction hood has a very simple structure.

Preferably, the collecting chamber is removably attached together with a valve fitted thereto, e.g. by means of a quick or screw connector to the dome.

Suitably, the valve is formed by a bore in the bottom of the chamber and a shut-off piece arranged below it, the latter being arranged, for example in the form of a ball of light material, in a kind of cage.

The invention will be explained in more detail below with reference to an embodiment shown in the drawing.

A single figure of the drawing shows in vertical section a suction hood according to the invention.

The suction hood shown comprises an actual suction piece 1, a connection socket 2 connected to its interior for a vacuum suction line (not shown) and a second connection socket 3 for a collection tank or container 4 (shown by dotted lines). This structure is plastic and a single piece.

In addition, a collecting chamber 5 with valves 6 arranged at its lower end 5 is arranged inside the collecting tank 4. This valve 6 is formed by a bore 8 in the bottom of the chamber 5 'and a valve body 9 made of e.g. light material, the valve body 9 being arranged in a cage 10.

The collecting chamber 5 is detachably attached to the suction piece by means of a quick connector 7. Thus, this whole can be easily cleaned.

When the suction piece 1 is placed against the body and a vacuum is developed, the valve body 9 rises to the position 9 'shown by the dotted line and then closes the bore and thus also the collecting chamber 5. As soon as the vacuum is stopped, the valve body 9 descends again to the lower position 9 and accumulates in the chamber 5. 4.

Of course, instead of a ball, the valve body 9 may be provided with a valve body otherwise formed, e.g. a hemispherical hollow plate with a guide passing through the bore 8. Other valves that can operate under vacuum are also possible.
