Foot-powered breastmilk pump with removable piston pump

A breast pump assembly, comprising:

• a breast hood assembly including a breast-shield;
• an otherwise manually operable piston pump having a piston cylinder with a chamber formed therein;
• a hand-drivable piston received for reciprocating movement within said chamber to generate, in use, a periodic suction within said breast hood assembly for the expression of mother's milk, said piston cylinder having a forward end and a rearward end, the forward end having means for connecting said forward end directly to said breast-hood assembly including said breast-shield, said piston pump when operated in a first mode is directly connected to said breast-hood assembly generating said periodic suction in said breast-hood through movement of said piston in said piston cylinder, said piston having a piston rod connected thereto which has means thereon for grasping said piston rod to drive said piston, which piston rod extends out of said rearward end of said piston cylinder;
• a base having a first means for releasably receiving and holding part of said piston pump;
• a riser rigidly mounted on said base and forming a pivot;
• a foot pedal having a second means for releasably receiving and holding another part of said piston pump;
• a pivot mounting for said foot pedal on said riser so that one end of said pedal can alternatively pivot toward and then away from said base;
• said first and second means for releasably receiving and holding said piston pump placing said piston pump in a configuration where pivoting movement of said pedal causes said piston to reciprocate within said cylinder to thereby generate a periodic suction when operated by foot in a second mode of operation.

A breast pump comprising:

• a pedal drive having a pedal member, a base upon which said pedal is mounted, a pedal mount on said base to which said pedal member is attached for movement relative to said base;
• a piston pump including a piston cylinder, a piston rod including a piston attached thereto, said piston reciprocally received within said piston cylinder for generating a periodic negative pressure within said piston cylinder, means for releasably affixing said piston cylinder directly to a breast shield assembly for conveying said periodic negative pressure to a breast placed within said shield for extraction of mother's milk when said piston pump is manually driven in a first mode of operation, said piston rod being adapted to be grasped;
• and
• means on said pedal drive for releasably mounting said piston pump on said pedal drive such that said piston pump is foot driven in a second mode of operation.

A breast pump, comprising:

• a breast shield assembly including a breast shield adapted to overlie and receive a breast therein, and a container in fluid connection with said breast shield to receive milk extracted from the breast;
• a piston pump having a piston cylinder which is releasably connected through a mating screw engagement directly to said breast shield assembly and which is manually drivable in a first mode of operation to generate a periodic negative pressure within said breast shield to pull and massage a breast placed within said shield to extract milk;
• a pedal drive having a pedal member, a base upon which said pedal is mounted, and a pedal mount to which said pedal member is attached for movement relative to said base;
• and
• a mounting mechanism on said pedal drive for releasably mounting said pump to said pedal drive to render said pump drivable by said pedal member in a second mode of operation.
