Patent ID: 7935043

Claim:
A blood processing apparatus comprising a separation chamber adapted to be mounted on a rotor of said blood processing apparatus; a tubing set coupled to said separation chamber for conducting blood, blood components, and fluids to and from said separation chamber, said tubing set including at least one inlet line in fluid communication with said separation chamber and at least one outlet line in fluid communication with said separation chamber; an anti-coagulant line having a pump-engaging loop, said anti-coagulant line being in fluid communication with said inlet line; a reservoir in fluid communication with said outlet line, said reservoir having means for detecting a pre-determined quantity of fluid in said reservoir; a component collection bag in fluid communication with said reservoir; a storage solution line in fluid communication with said anti-coagulant line at a junction above said pump-engaging loop with respect to fluid flow, and a crossover line in fluid communication with said storage solution line below said pump-engaging loop with respect to fluid flow, said crossover line coupling said storage solution line to said reservoir, and means for selectively permitting fluid flow through said crossover line, whereby a predetermined quantity of storage solution may be delivered to said component collection bag through said reservoir.
