Problems solved by technology

The removable membrane is an expensive additional part that requires cleaning
Moreover, the casings used for such membranes have an unattractive appearance and hinder the visibility and cleaning of the teat, while the movement of the membrane during operation consumes energy
Porous membranes are difficult to install in place and difficult to keep clean, and have been known to break easily
Mazes are not 100% safe and cannot be considered foolproof

Embodiment Construction

[0037] Figure 1-Figure 3 It relates to a breast pump device 1 according to the invention comprising an expressing sleeve 2 and a pressure unit 3 for generating a pressure cycle during which a vacuum is alternately created and released. The expression set 2 comprises a breast pump body 20 and a milk container 4 which is attachable (for example by screwing) to the breast pump body 20 so as to close the lower end of the breast pump body 20 . The pressure unit 3 may comprise any suitable means for generating pressure, and may be, for example, an electric vacuum unit, or a manual pressure unit or a pump. The pressure unit 3 is connected to the extrusion sleeve 2 via a pipe 30 . Such a configuration allows the remote arrangement of the pressure unit 3 with respect to the expression set 2 so that the size of the part of the breast pump device 1 that is to be applied to the user's breast can be kept within reasonable limits. This does not change the fact that the pressure unit 3 ca...

Abstract

An expression kit (2) for use in a breast pump device (1) for extracting breast milk from a human breast comprises a breast pump body (20) having a first pressure chamber (21), a second pressure chamber (22), and a membrane portion (5) separating the first and the second pressure chamber (21, 22) from each other. The membrane portion (5) is configured to form a barrier between the first and the second pressure chamber (21, 22) for preventing leakage of human breast milk from the second pressure chamber (22) to the first pressure chamber (21), yet to allow for air exchange between the first andthe second pressure chamber (21, 22), wherein the membrane portion (5) is hydrophobic and has the shape of a solid sheet being provided with holes (50) which are configured for rendering the sheet permeable to air and impermeable to liquid.

Description

technical field [0001] The invention relates to an extrusion kit for a breast pump device for extracting breast milk from a human breast, the extrusion kit comprising a breast pump body with a first pressure chamber, a second pressure chamber and a membrane part, the membrane part separates a first pressure chamber and a second pressure chamber from each other, wherein the first pressure chamber is configured for connection to a pressure unit for generating pressure in the first pressure chamber, wherein the second pressure chamber comprises a breast receiving funnel, a milk outlet, and a milk pathway from the breast receiving funnel to the milk outlet, and wherein the membrane portion is configured to form a barrier between the first pressure chamber and the second pressure chamber for preventing human breast milk from entering the second pressure chamber The chamber leaks to the first pressure chamber, but allows air exchange between the first and second pressure chambers. ...
