Abstract
A blood separation device has a controller configured to execute a first and a second version of a blood separation procedure. Information regarding a blood source is analyzed to determine whether to implement the first version of the procedure or the second version. This may include an analysis of the age, weight, and/or sex of the blood source, along with whether the blood source has previously been the subject of a blood separation procedure. The second version may allow for a greater percentage of the blood or red blood cells of the blood source to be outside of the body of the blood source (in a fluid flow circuit mounted to the device) at any time during the procedure. The second version may also or alternatively allow for a higher blood cell separation efficiency than the first version, along with separating the blood in a larger blood separation chamber.
