ABSTRACT:
The breast pump (1) for sucking off breast milk has a suction bell (10), which is intended to be laid against the breast and which is connected with a storage container (12) for pumped-off milk arranged at an angle to the longitudinal axis (A.sup.3) of the suction bell and with a suction pump (15) driven by an electric motor (11), in order to produce sufficient suction for the pumping-off process inside the suction bell; the pump (1) has an attachment housing (18) which comprises two limbs (14, 16) connected to each other at an angle, which housing is connected in a detachable manner with the suction bell (10) and contains the electric motor (11), a low voltage current source (13) for the latter, for example, a battery or an accumulator, and the suction pump (15). The longitudinal axis (A.sup.1) of one (14) of the limbs of the housing lies practically parallel to the longitudinal axis (A.sup.3) of the suction bell (10) and the longitudinal axis (A.sup.2) of the other limb (16) of the housing lies practically parallel to the longitudinal axis (A.sup.4) of the storage container (12).
The new breast pump can be made of light and comparatively inexpensive parts and can be used as a compact entity similar to manual pumps, yet with the advantages of the mechanical drive. Possible vibrations act transverse to the mamilla axis and in general are felt to be beneficial and lactogenic.
