With the manual piston pump the revised forma breast pump assembly body null which has the motor Drive body which is used

摘要

An improved breast pump assembly, including a manually operable breast pump that can be used in a manual mode by hand-driving the breast pump, provides a motor drive unit (15) which is adapted to receive and hold the manually operable piston pump (11) of the breast pump, with a pump drive for reciprocating the piston rod (19) of the piston pump in substantially the same stroke as would occur in optimum manual driving of the breast pump.
