Description

TECHNICAL FIELD

[0001] The invention relates to a portable breast pump and to a suction unit for use with this portable breast pump.

PRIOR ART

[0002] Portable breast pumps are known. They have the advantage that a mother can carry them along everywhere and thus maintain a certain degree of independence even throughout the months she is breast-feeding. It is not always easy, however, to find a suitable area in which the mother can express the milk without being disturbed. Working mothers in particular often have to do this in the ladies' toilets in the workplace. In such areas, however, it is usually difficult to find a suitable set-down surface for the breast pump.

[0003] U.S. Pat. No. 6,379,327 discloses a breast-pump system in the case of which the mother can carry all the elements of the breast pump on her body. This system comprises a bra with an integrated breast shield and a wide band which is worn around the stomach and has a first pocket for accommodating a suction unit and a second pocket for accommodating a milk-receiving container. The suction unit and the milk-receiving container are connected to the breast shield, in each case via a dedicated line. The entire system is worn beneath the clothing. This has the disadvantage that the mother always has to carry the breast pump around with her, which is regarded as being awkward and hinders the mother in doing anything else. In addition, the suction unit is of a not inconsiderable weight, with the result that the mother will not really want to carry it for a long period of time. Furthermore, the operating buttons of the breast pump are likewise concealed beneath the clothing and are thus not easily accessible.

[0004] A similar breast pump is also disclosed in U.S. Pat. No. 6,440,100, the arrangement of the suction unit not being explained specifically here.

[0005] GB-A-2,366,732 describes a portable breast pump which is carried over the shoulder on a support, the support being length-adjustable. The suction unit is arranged at the bottom front end of the support. The breast attachment cap and the milk-receiving container are fastened on the suction unit by a coupling part. This system can indeed be worn above the clothing, and thus need only be attached as required. The disadvantage, however, is that it is of relatively rigid design, with the result that the mother is hardly able to move as the milk is being expressed. In addition, the suction unit has to be of relatively small design in order that the support does not protrude too far. Small suction units, however, usually also have a low suction capacity and/or have only a rudimentary control means.

DESCRIPTION OF THE INVENTION

[0006] It is an object of the invention to provide a portable breast pump which eliminates the abovementioned disadvantages.

[0007] This object is achieved by a breast pump and by a suction unit for use with this breast pump having the features of patent claims 1 and 2, respectively. The breast pump according to the invention has a suction unit and a collecting unit which are connected to one another by means of a flexible suction line. The suction unit has a housing which is provided with at least one fastening means. The fastening means serves for fastening the housing on a carrying element which can be fastened on the mother's body.

[0008] The connection between the carrying element and fastening means is preferably releasable. It is preferably possible for the housing to be fastened on the mother's trouser or dress belt or to be carried on a loop around the neck.

[0009] This breast pump with its suction unit allows the mother to move freely even as the milk is being expressed. In addition, the mother can select the location and how she wishes to carry the suction unit.

[0010] If the housing is of flat design, it is more comfortable for the mother to carry. In addition, this prevents the mother from catching herself anywhere on the housing. It is advantageous, furthermore, that the housing may be configured relatively freely in terms of shape, with the result that it can be carried as a fashion accessory without being recognizable at first glance as the suction unit of a breast pump. In addition, the suction unit may be of sufficiently large design to accommodate a sufficiently large electric storage cell and the desired electronics.

[0011] Since the suction unit is carried in an exposed manner, any possible operating buttons are easily accessible. In order to increase the accessibility yet further, they are preferably arranged in a front side of the housing.

[0012] Further advantageous embodiments can be gathered from the dependent patent claims.

BRIEF DESCRIPTION OF THE DRAWING

[0013] The subject matter of the invention is explained hereinbelow with reference to a preferred exemplary embodiment which is illustrated in the attached drawing, in which:

[0014] FIG. 1 shows a portable breast pump according to the invention with a suction unit, in a first carrying variant;

[0015] FIG. 2 shows a breast pump according to FIG. 1 in a second carrying variant; and

[0016] FIG. 3 shows the suction unit according to FIG. 1 in a view from behind.

PREFERRED EMBODIMENT

[0017] FIG. 1 illustrates a portable breast pump according to the invention. The breast pump has a collecting unit A and a suction unit 1 which is connected thereto via a suction line 5. The suction line 5 is usually a flexible plastic tube.

[0018] In this preferred example, the collecting unit A comprises a breast shield 2, a coupling element 3 and a milk-receiving container 4. The coupling element 3 connects the breast shield 2 to the milk-receiving container 4 to form a rigid unit which can be attached to the mother's breast and can be held in the hand as the milk is being expressed. However, it is also possible for the connection between the milk-receiving container 4 and breast shield 2 to be a flexible configuration and for these to be connected to one another by means of a further connecting tube. It is thus possible for the breast shield 2 to be retained on the breast or integrated in a bra. In this variant, the container 4 may be provided with a fastening means in order to attach it, for example, to a belt. It is also possible, however, for it to be held in one hand or positioned on a set-down surface. The embodiment with the rigid unit, however, is the preferred solution in respect of mobility and handling.

[0019] The suction unit 1 comprises the elements, which are known in the prior art, for producing a negative pressure in the breast shield 2 which is sufficient for expressing the milk. These elements comprise a suction pump (not illustrated), control electronics and an electric storage element, for example a battery. All of these elements are arranged in a common housing 10. This preferably consists of plastic and is of rigid design. Either it has connection openings for a plug-in connection for connection to an electric charging device for the storage element or it may be opened at least in the region of the battery, in order for the battery to be exchanged.

[0020] The housing 10 is preferably of flat design, with a front side 11, a rear side 12 and a lateral surface 13 which connects the two sides. The cross section of the housing 10 may be selected as desired. It may be, in particular, of round, oval or polygonal design. A recess 13′ is preferably provided on the housing 10, for example in the lateral surface 13, for the purpose of accommodating one end of the suction line 5. This suction line 5 can preferably be plugged in a releasable manner into this recess 13′.

[0021] At least one operating means 14 for actuating the suction pump is provided on the housing 10. In this example, this means is constituted by buttons which are incorporated in the front side 11 of the housing 10.

[0022] A fastening means 15, furthermore, is arranged on the housing 10, in order to fasten the housing 10 on a carrying element. In this example, the carrying element is a belt G. The fastening means 15 is preferably arranged on that side of the housing 10 which is located opposite the operating means 14, so in this case on the rear side 12, as can be seen in FIG. 3. In this example, the fastening means 15 comprises a resilient clip 15′, in particular made of metal or plastic, and a plug-in closure part 15″, in this case made of plug-in pins 150 which are provided, in part, with retaining hooks 151. It is also possible, however, for the housing 10 to be provided just with the clip 15′ or just with the plug-in closure part 15″. In addition, it is possible to use other known fastening means, for example a touch-and-close fastener.

[0023] The suction unit 1 according to the invention can easily be hooked onto a belt G by means of the clip 15′. This belt need not be as special belt, but, rather, may be any belt selected individually by the mother.

[0024] In the embodiment according to FIG. 2, the suction unit 1 is carried by way of a loop S around the neck. The loop S may be firmly connected to the housing 10, but it is preferable to select a releasable connection. For example, the bottom end of the loop S may be provided with an associated plug-in closure part 6 for connection to the plug-in closure part 15″, as is illustrated in FIG. 3.

[0025] It is also possible, however, for the suction unit 1 to be carried in other ways, for example on the arm or hung over the shoulder.

[0026] The breast pump according to the invention is easy to operate, allows the milk to be expressed even in confined areas with no set-down surfaces and, in addition, does not hinder the mother's mobility even as the milk is being expressed.
