  • Closed system and methods for mixing additive solutions while removing undesired matter from blood cells
    Patent number: 6053885
    Abstract: A blood processing system and associated method include a first variable volume chamber to hold blood and a second variable volume chamber to hold additive solution for blood. The system and method further employ a separation device to remove undesired material from blood. An actuated element exerts external force simultaneously upon both first and second variable volume chambers to expel a first flow of blood from the first variable volume chamber and a second flow of additive solution from the second variable volume chamber. The system and method mix outside the first and second variable volume chambers the blood flow with the flow of additive solution to create a mixed flow comprising blood and additive solution. The system and method direct the mixed flow of blood and additive solution through a filter to remove undesired matter from the blood.
