Milk extraction device
First Claim
1. A milk extraction device, comprising at least one extraction element (20) having an intermediate piece (22) releasably attached to an opening of a receptacle (21) and connected in a vacuum-tight manner with a breast attachment element (23.1) for exerting an extraction action on a breast, a headpiece (24) connectible with the attachment element in a vacuum-tight manner and into which an elastic liquid-proof separating membrane (30) is inserted, which transmits a variable vacuum from a pump unit (10) to an interior of the intermediate piece (22) and of the breast attachment element (23.1), whereinthe headpiece (24) is releasably connected to a coupling section (22.1) of the intermediate piece (22) by a matched counter-coupling section (24.11).

Abstract
A milk extraction device including at least one extraction part with an intermediate piece that is, or can be, detachably fastened on the opening of a receptacle and that is linked with a breast piece in a vacuum-tight manner so as to exert a sucking effect on the breast. The device also includes a cap that is, or can be, linked with the intermediate piece in a vacuum-tight manner. An elastic, liquid-tight separating membrane is inserted in the cap and transmits a varying vacuum from the pump unit to the interior of the intermediate piece and the breast piece. The cap is detachably connected to an adapted coupling section of the intermediate piece by a coupling counter-section, thereby meeting increased hygienic standards and simplifying the use of the milk extraction device.
