ABSTRACT:
A system for priming an extracorporeal blood circuit is described. The system includes a fluid circuit with an air venting mechanism, a reversible pump, arterial and venous lines, a prime waste bag and a switchable coupler selectively connecting the arterial and venous lines to the waste bag or alternatively interconnecting the arterial and venous lines. A priming fluid is connected to the circuit and circulated in the circuit under different configurations of the arterial and venous line connections.
