1. A system for pumping a medical fluid through a line in an infusion pump, the system comprising:
a pumping chamber in the infusion pump comprising:
an inlet in fluid connection with a fluid source; and
a pump outlet;
an inlet sealing member comprising a sealing spring;
a pump compressing member comprising a return spring; and
a pump plate directly attached to the inlet sealing member and the pump compressing member;
wherein during a compressive stroke the pump compressing member is driven towards the pumping chamber and the sealing spring transmits a driving force to the inlet sealing member, and
wherein the compressive stroke causes a restriction of retrograde flow of fluid from the pumping chamber through the inlet and causes an increase in pressure within the pumping chamber.
