Breast pump with flexible pump body

The invention relates to a breast pump with a flexible pump body attached thereto. With such breast pumps, the excess breast milk is pumped out during the breastfeeding period of a mother.

A breast pump with a flexible pump body attached to it is already known, the pump body from consists of a rubber ball that has an opening that with one provided at the top of the breast pump

1U opening communicates airtight. The breast pump has two openings with different diameters and is on the underside with a milk and milk basin Mistake. The larger diameter opening is designed so that breasts of different sizes can be pumped out the milk can be applied to this opening. After placing the breast pump on the breast pump to be aspirated Breast, a negative pressure is created in such a way that the rubber ball is compressed and then released again will. The fact that the rubber ball returns to its original shape after it is released means that air is released from the breast pump deducted. Since the negative pressure is only generated by a single pump stroke, it is after entering a certain amount of milk from the breast into the milk collecting basin after the first pump stroke another pump stroke perform. This is done by compressing the rubber ball again while opening the pump body is separated from the chest so far that the compressed air generated by the compression of the rubber ball is unhindered can flow out, and then after the pump body opening has been placed on the chest again,

lets go of the rubber ball again. Repeat this procedure until the desired amount of milk has been sucked off and emptied into a suitable container.

A disadvantage of the known breast pump is that " man as soon as the Wed I collecting basin on the breast pump with Milk is filled, this milk must be poured into a container. Another handicap of the well-known breast pump ordered in that each time you squeeze the rubber ball Pump body must be lifted from the chest so that the Air can escape.

The invention is based on the object of the breast pump

of the type mentioned at the beginning in such a way that they

ter to handle and the constant stress on the chest

Removing and attaching the breast pump is not necessary.

The object set is achieved by the invention specified in claim 1.

With the breast pump according to the invention with attached to it Any number of flexible pump bodies can be created by alternately compressing and releasing the pump body Perform pump strokes one after the other without using the breast pump must be withdrawn from the chest. The execution of several pump strokes is possible that when squeezing of the pump body after the air contained therein through the check valve arranged in the wall of the pump body is printed outside, while that in the area between milk pump and pump body arranged check valve ge is closed. When you let go of the pump body, due to its inherent elasticity, it returns to its original shape, which is reflected in the wall of the Pump body arranged check valve closes so that

Air is sucked in from the breast pump via the now open non-return valve between the breast pump and the pump body. This process can be repeated until the required amount of milk has been sucked off by the dilution of the air in the breast pump.

Advantageous further developments of the invention are described in the subclaims.

The embodiment of the invention according to claim 4 is particularly advantageous when the breast pump is used as a disposable breast pump, but the pump body and the two valves are to be reused .

Several exemplary embodiments of the invention are shown in the drawing. Show it:

2 shows another breast pump with a flexible pump body attached to it, also in a longitudinal section.

The breast pump 1 shown in Fig. 1 has three openings » a breast-appropriate opening 9 with a milk-conducting neck 11, an opening 13, which with a screw socket 8 for a tight connection - by silicone, latex or a rubber seal 7 - to the milk bottle 6 or 6 a is connected. The pump body 2 is designed as a rubber ball, the tubular extension 14 of which is pushed onto the tubular extension 5 that forms the opening 12. In the wall of the pump body 2 is a non-return valve 4 and in the hose-like extension piece 5, a check valve 3 is provided. The direction of flow
