Abstract
Systems and methods are provided for separating blood into two or more separated blood components. The system includes a blood separation chamber with a single stage having five ports connected thereto. The five ports include a blood inlet port, a red blood cell outlet port, a platelet-rich plasma outlet port, a platelet-poor plasma outlet port, and a buffy coat outlet port. In the single stage, blood may be separated into a variety of components, such as red blood cells and platelet-rich plasma or red blood cells, platelet-poor plasma, and buffy coat. Depending on the components into which the blood is to be separated, flow out of one or more of the outlet ports may be prevented.
