Abstract:
A breast pump having two modes of manual operation, comprising:a hood body for placement over a breast, said hood body having a funnel-shaped portion within which the breast is received;a piston pump connecting with said funnel-shaped portion, said piston pump further comprising a cylinder and a piston slidably engaged with said cylinder for reciprocating movement occurring along an axis, whereby said reciprocating movement generates an alternating pressure in the hood body on the breast to express milk therefrom;a first manually operated mechanism mounted to said breast pump for generating said reciprocating movement of said piston pump, said first mechanism having a member that is moved by hand in a direction generally radial to said axis during one stroke of said reciprocating movement, and further said first mechanism being operable by the user using one hand to both operate said first mechanism and to maintain said breast pump in position against her breast;a second mechanism for generating said reciprocating movement of said piston pump, whereby said second mechanism moves in a direction generally parallel to said axis during one stroke of said reciprocating movement, and further said second mechanism is adapted to be grasped by the user and being operable by the user using one hand to operate said second mechanism and another hand to maintain said breast pump in position against her breast; anda container for expressed milk in communication with said funnel-shaped portion, said container being located downstream from said funnel-shaped portion.
