In this method for treating circulatory fluid constituents, first a selective switching means switches the upstream side of a first circulatory fluid treatment device to receive from a source a flow of circulatory fluid, and switches the downstream side of the first circulatory fluid treatment device to send to a destination the flow of circulatory fluid. Next, the selective switching means, while maintaining this switching of the flow of circulatory fluid from the source into the upstream side of the first circulatory fluid treatment device, switches the downstream side of the first circulatory fluid treatment device to communicate the flow of circulatory fluid to the upstream side of a second circulatory fluid treatment device, further switches the downstream side of the second circulatory fluid treatment device to send to the destination the flow of circulatory fluid, and further discommunicates the downstream side of the first circulatory fluid treatment device from sending flow of circulatory fluid to the destination. Finally, the selective switching means, while maintaining the sending to the destination of the flow of circulatory fluid from the downstream side of the second circulatory fluid treatment device, switches the upstream side of the second circulatory fluid treatment device to receive the flow of circulatory fluid from the source, and further discommunicates the upstream side of the first circulatory fluid treatment device from receiving flow of circulatory fluid from the source. An apparatus practicing this method is also disclosed. |
