An extracorporeal blood processing system is disclosed which includes a variety of novel components and which may be operated in accordance with a variety of novel methodologies. For instance, the system includes a graphical operator interface which directs the operator through various aspects of the apheresis procedure. Moreover, the system also includes a variety of features relating to loading a blood processing vessel into a blood processing channel and removing the same after completion of the procedure. Furthermore, the system also includes a variety of features relating to utilizing a blood priming of at least portions of the apheresis system in preparation for the procedure. In addition, the system includes a variety of features enhancing the performance of the apheresis system, including the interrelationship between the blood processing vessel and the blood processing vessel and the utilization of high packing factors for the procedure. |

DETAILED DESCRIPTION The present invention generally relates to extracorporeal blood processing.
Since each of the various aspects of the present invention may be incorporated into an apheresis system (e.
g.
, whether for blood component collection in which "healthy" cells are removed from the blood or for therapeutic purposes in which "unhealthy" cells are removed from the blood), the present invention will be described in relation to this particular application.
However, at least certain of the aspects of the present invention may be suited for other extracorporeal blood processing applications and such are within the scope of the present invention.
An apheresis system which may embody one or more aspects of the present invention generally includes a blood component separation device (e.
g.
, a membrane-based separation device, a rotatable centrifuge element, such as a rotor, which provides the forces required to separate blood into its various blood component types (e.
g.
, red blood cells, white blood cells, platelets, and plasma)).
In one embodiment, the separation device includes a channel which receives a blood processing vessel.
Typically, a healthy human donor or a patient suffering from some type of illness (donor/patient) is fluidly interconnected with the blood processing vessel by an extracorporeal tubing circuit, and preferably the blood processing vessel and extracorporeal tubing circuit collectively define a closed, sterile system.
When the fluid interconnection is established, blood may be extracted from the donor/patient and directed to the blood component separation device such that at least one type of blood component may be separated and removed from the blood, either for collection or for therapy.
A first aspect of the present invention relates to enhancing the ease of loading a blood processing vessel into a channel which is associated with a centrifuge rotor.
In one embodiment of this first aspect, the centrifuge rotor includes a blood processing vessel loading aperture in its sidewall which extends only part of the way through the centrifuge rotor and then extends upwardly through the top of the centrifuge rotor
