초록 ▼

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.

대표청구항 ▼

[ I claim:] [1.] A blood processing system comprisinga first variable volume chamber to hold blood,a second variable volume chamber to hold additive solution for blood,a separation device to remove undesired material from blood,an actuated element comprising plates spaced apart to accommodate placement of both the first variable volume chamber and the second variable volume chamber between the plates and including means for moving the plates together to exert a squeezing force simultaneously upon both first and second variable volume chambers to simultaneously 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, anda fluid flow system to convey fluid flow in response to the squeezing force exerted by the actuated element and without application of external pumping force, the fluid flow system including a first branch communicating with the first variable volume chamber to convey the first flow of blood, a second branch communicating with the second variable volume chamber to convey the second flow of additive solution simultaneously with and independent of the first flow, a third branch communicating with the first and second branches to mix outside the first and second variable volume chambers the blood from the first branch with the additive solution from the second branch to create a mixed flow comprising blood and additive solution, the third branch further communicating with the separation device to direct the mixed flow of blood and additive solution through the separation device.
