Abstract

762,701. Breast pumps. VEB ELEKTROGERATEWERK SUHL. May 31, 1954, No. 16051/54. Class 81(2) A breast pump has the motor, pump, suction cup and receiving bottle combined as a unitary arrangement so that it may be self-applied by the patient. The electric motor 1 drives a crank 12 and thus actuates a piston 13 to provide pressure pulsations in a duct 18 leading to the glass suction cup 3. A side tube 21 in the wall of the cup 3 supports the bottle 4 but communication between the two is limited by a one-way flap valve formed by a rubber sleeve 23 covering a lateral orifice 22. This valve allows milk to flow into the bottle but, by closing during the suction phase, it reduces the volume which has to be evacuated and thus permits the use of a small capacity pump. The bore 18 extends through a plug member 17 which is rotatable in a sleeve 15 so that the bottle can always hang vertically irrespective of the angle at which the motor is held.
