INVENTION: SUCTION HOOD FOR A DEVICE FOR SUCKING OFF
BREAST MILK
ABSTRACT OF THE DISCLOSURE
A suction hood which essentially comprises a hood body or member provided with connections for a suction line and for a receiving container or receptacle. Additionally, there is arranged at the suction hood a collecting or catch chamber, at the outlet of which there is provided a valve which is maintained in a closed position by means of an operating vacuum. Such construction renders possible a more balanced and reliable operation of the entire suction device.

ABSTRACT OF THE DISCLOSURE
A suction hood which essentially comprises a hood body or member provided with connections for a suction line and for a receiving container or receptacle. Additionally, there is arranged at the suction hood a collecting or catch chamber, at the outlet of which there is provided a valve which is maintained in a closed position by means of an operating vacuum. Such construction renders possible a more balanced and reliable operation of the entire suction device.
Description
115~L7 BACKGROUND OF THE INVENTION
The present invention relates to a new and improved construction of a suction hood for a device for sucking off breast milk, comprising a hood body or member, a connecting stud or connection for a vacuum line or conduit and a connection stud or connection for a receiving container or receptaclç~
Suction hoods of this general type are known to the art and constitute an essential component of suction equipment or devices for sucking off breast milk. Of course, such devices contain a suction pump which, as a rule, inter-mittingly generates a vacuum or negative pressure. Apart from the purely hygienic requirements for such equipment there also exist technical probl~ms which are at least partly insufficiently solved with the prior art cons-tructions.
Thus, it repeatedly happens that the ~ilk reaches the vacuum line or even the pump. This is counteracted by axranging so-called safety volumes between the hood and the pump which, however, is associated with a fairl~ great technical expenditure. Additionally, new problems are created, for example, with refexence to the system or the actual operation, since varying degrees of vacuum or negative pressure can occur.
~157~
SUMMAF~Y OF TI~E INVENTION
Therefore, it is a primary object of the present invention to provide a new and improved construction of a suction hood which is not associated with the aforementioned drawbacks and limitations of the prior art.
Another and more specific object o the present invention is directed to devising a ne~ and improved construction of suction hood for equipment for sucking off breast milk, which suction hood is relatively slmple in construction and design, economical to manufacture, extremely reliable in operation, not readily subject to breakdown or malEunction, requires a minimum of maintenance and servicing, and is effective in positively sucking off breast milk without fauling the equipment.
Now in order to implement these and still further objects of the invention, which will become more readily apparent as the description proceeds, the suction hood of the present development is manifested by the features that following the hood body or member there is arranged a collecting or catch chamber, at the outlet of which there is provided a valve. This valvs closes a throughpassage or passage leading from a collecting or catch chamber to the receiving container when there is applied a vacuum or negative pressure, but opens such throughpassage or passage during the remainder of the operation.
~ 57~17 Owing to the provision of the collecting or catch chamber which is equipped with a valve, milk can be pumped, for instance, to a receiving container which i5 in the form of a plastic bag or sack, since the vacuum or negative pressure no longer affects the receiving container. Moreover, an overflow can be avoided, since the valve opens promptly and the sucked-off milk can flow off into the receiving container.
The novel embodiment of suction hood according to the invention solves leakage or sealing problems and makes it possible to employ smaller pumps, since the volume of the vacuum or negative pressure which is necessary for intermittent operation can be considerabl~ smaller in comparison to known solutions;i~is unnecessary to create a vacuum for either the volume of the receiving container because of the valve or for the safety volume because of the non-existence of any such safety volume~
A particularly important advantage of the present invention resides in the fact that there can be applied a constant negative pressure or vacuum, since no variable volumes are present in the system. Heretofore the volume of the receiving container changed during the filling thereof.
Finally, it should be here mentioned that the new hood is exceedingly simple in its construction and design.
1 ~7~:~7 The collecting or catch chamber is removably attached, preferably together with the valve arranged therein, to the rest of the hood, by means of a suitable sna~ closure or threaded ox rotatable closure element.
Advantageously, the valve is formed by providing a bore in the floor or base of the collecting chamber and thrgugh the provision of a closing body or closure element which is arranged beneath such bore. Such closing body or closure element can be ormed of a light material and construc-ted in the form of a cage.
BRIEF DESCRIPTION OF THE DRAWING
The invention will be better understood and objects other than those set forth above will become apparent when consideration is given to the Following detailed description thereof. Such description makes reference to the annexed single drawiny which depicts a vertical sectional view of an exemplaxy embodiment of a suction hood according to the invention.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
. . _ . .
Turning now to the single Fiyure of the drawing, the therein illustrated suction hood or suction hood arrangement will be seen to comprise an actual hood body or hood member 1, a connection stud or connection 2 which flow communicates with l 1157~7 the internal space la thereof and leads to a not particularly illus~rated vacuwm suction line or conduit, and a further connection stud or connection 3 for a container or receptacle 4 which is indica~ed by broken or phantom lines. The container or receptacle 4 may be formed of plastic and is constructed as one piece.
Inside the connection 3 there is additionally provided a collecting or catch chamber 5, at the lower end or base region 5' of which there is arranyed a valve 6. This valve 6 is composed of a bore 8 formed in the floor or base 5" of the collecting chamber 5 and a valve body 9. The valve body 9 can be formed, for instance, as a ball consisting of any suitable light materialandcanhearranged in a cage or cage-like housing 10.
The collecting or catch chamber 5 is desirably removably attached to the rest of the hood body 1 by means of a suitable releasable closure or attachment means 7, which may be for instance a standard snap closure or a rotatable or threaded closure or locking means. Thus, the entire device can be cleaned relatively effortlessly.
When the hood body 1 is held against the breast of the user and a vacuum or negative pressure is formed, the valve body 9 is lifted to the position 91, which has been indicated by broken lines, and thus closes -the bore 8 and 1~57417 therewi-th the collecting or catch chamber 5. As soon as the negative pressure or vacuum is di.scontinued, the valve body 9 drops into the lower position g shown in ull lines and the milk which has been collected in collecting chamber 5 can flow off downwardly through the cage-like housing 10 into the receiving container 4.
Of course, the valve body 9 which is here constructed, by way of example and not limitation, as a ball in the embodiment under discussion, ~lso could be replaced by a valve body of a different design, such as, for instance, a semi-spherical cup equipped with a guide which extends through the bore 8. Other valve or flap means which can be activated hy negative pressure or vacuum are also conceivable.
While there are shown and described preferred embodiments of the invention, it is to be distinctly understood that the invention is not limited thereto but may variously be embodied and practiced within the scope o the following claims. ACCORDINGLY,
