Patent ID: 8622720

Claim:
A reciprocating fluid pump for pumping a subject fluid, comprising: a pump body; a first subject fluid chamber within the pump body; a second subject fluid chamber within the pump body; a first plunger located at least partially within the pump body, the first plunger comprising a flexible material and configured to expand and compress in a reciprocating action to pump subject fluid through the first subject fluid chamber within the pump body during operation of the reciprocating fluid pump; a second plunger located at least partially within the pump body, the second plunger comprising a flexible material and configured to expand and compress in a reciprocating action to pump subject fluid through the second subject fluid chamber within the pump body during operation of the reciprocating fluid pump; at least one first magnet disposed within the first plunger; and at least one second magnet disposed within the second plunger; wherein the at least one first magnet and the at least one second magnet are located and configured to impart a force on each other during at least one of the expansion and compression of the first plunger and second plunger in the reciprocating action within the pump body; and wherein the first plunger is not structurally coupled to the second plunger, such that the first plunger and the second plunger are independently movable during operation.
