1. A method of priming an extracorporeal blood circuit including a venous line, an arterial line and a line to a prime waste container, wherein any two of the venous line, arterial line and line to the waste container can be selectively in fluid communication with each other and a chamber including a filter that allows air to escape from the chamber, comprising:

  • occluding one of the venous line or the arterial line while connecting the other of the venous or arterial line to the prime waste container;

    flowing priming fluid through the circuit so that the priming fluid flows out of either the arterial or venous line into the waste container;

    occluding the line to the waste container and connecting the arterial and venous lines together;

    circulating priming fluid through the closed extracorporeal circuit; and

    reversing the flow through the circuit, whereby air is removed from the circuit. wherein the steps of occluding one of the venous line or the arterial line, flowing priming fluid, occluding the line to the waste container, circulating priming fluid and reversing the flow through the circuit are done without need for human manipulation.
