Problems solved by technology

[0013] More rigid media separation membranes have the disadvantage of having a greater pressure drop across the membrane
This is especially problematic in the case of large pan or funnel sizes, because in these cases the pump uptake volume of the breast pump system is usually no longer large enough to apply a sufficient negative pressure to the mother's breast

Embodiment Construction

[0048] Figure 13 Shown is a breast pump system with a vacuum pump 6, a housing 5 placed on the pump membrane of the vacuum pump 6, a suction line 3 connecting the housing 5 to the adapter 2, a breast pump connected to the adapter 2 Shroud 1 and milk container 7 also connected to adapter 2 . Preferably, the breastshield 1 is inserted into the adapter 2 and detachably connected thereto. However, the breastshield can also be integrally molded onto the adapter 2 . In this example, a double pump with two housings, two suction lines and two breastshield units is shown.

[0049] The outer cover 5 , the adapter 2 and the breastshield 1 are preferably made of plastic, wherein the outer cover 5 and the adapter 2 are preferably rigid and the breastshield 1 can be rigid, soft or semi-soft.

[0050] The breastshield 1 shown here is an independent invention. Said breastshields are described in detail in an application entitled "Breastshields", filed on the same date by the same applica...

Abstract

The invention relates to an adapter (2) for a breast shield (1) of a breast pump for pumping human breast milk. Said adapter has a chamber (280) having a first opening (282) leading to the breast shield (1) and a second opening (283) remote from the breast shield. The adapter (2) also has a flexible media separation membrane (4), which is accommodated in the chamber (280) and separates the chamber (280) into a pump-side and a breast-shield-side area. The chamber (280) tapers toward the breast-shield-side opening (282). The chamber (280) has the shape of a spherical dome which is cut off in the tapering area thereof. The media separation membrane (4) likewise has substantially the shape of a flattened spherical dome having a flat top side (411), wherein the flat top side (411) of the media separation membrane (4) faces the breast-shield-side opening (202) of the chamber (280). The adapter according to the invention permits a minimum pressure drop over the media separation membrane and ensures a reliable return to the original shape of the media separation membrane.

Description

technical field [0001] The invention relates to an adapter for a breastshield of a breast pump for pumping human breast milk, said adapter having a medium separation membrane. Background technique [0002] Breast pump systems for expressing human breast milk are well known. The breast pump system has a manually or electrically operated vacuum pump, at least one breast shield for supporting on the mother's breast, and a milk collecting container in which pumped milk is received. The breastshield is connected directly or via a suction line to a vacuum pump so that a periodically varying negative pressure can be applied to the breast in the breastshield in order to pump milk from the breast. [0003] Known breastshields are detachably held in the adapter or are fixedly connected to the adapter. Adapters for connection to the milk container and to the vacuum pump. In this case, the pump can be connected to the adapter via the suction line or be arranged directly on the adapte...
