Abstract
Systems and methods for processing blood use at least one fluid activated pump and at least one fluid activated valve. The systems and methods apply positive and negative fluid pressures to operate the pump and valve. Different pressure conditions are applied to the pump and the valve, to insure that a valve used in conjunction with a pump is not overcome by the pressure applied to operate the pump, and that both the valve and pump are not overcome by normal system processing pressures.
