Claim 0:
1. A blood separation device, comprising:
a separator configured to receive a blood separation chamber;
a pump system; and
a controller configured to execute a blood separation procedure for a blood source connected to the blood separation device in which the controller
(a) determines or is provided with an initial target amount of blood to be processed in order to collect a target yield of at least one target blood component,
(b) commands the pump system to convey blood from the blood source into the separator,
(c) commands the separator to separate said at least one target blood component from the blood in the separator,
(d) commands the pump system to convey said at least one target blood component out of the separator,
(e) continues executing (b)-(d) until the initial target amount of blood to be processed has been conveyed from the blood source into the separator and said at least one target blood component separated from the initial target amount of blood to be processed has been conveyed out of the separator as an actual yield of said at least one target blood component, and
upon the initial target amount of blood being processed, (f) completes the blood separation procedure, with the blood source being disconnected from the blood separation device, wherein the controller is further configured to execute a subsequent iteration of the blood separation procedure for the same blood source in which the initial target amount of blood to be processed is replaced with an adjusted target amount of blood to be processed based at least in part on a difference between the target yield and the actual yield.
