Blood collection and separation system

A system for collecting and processing blood from a donor, the system comprising:

• venous-access means for drawing whole blood from the donor therethrough;
• a centrifuge rotor capable of holding the blood;
• means for spinning the rotor so as to cause the blood to separate into plasma and red blood cells;
• a first container for storing both an anticoagulant and the separated plasma;
• a second container for storing the separated red blood cells;
• tube means for connecting the rotor, first container, and venous-access means, so as to permit anticoagulant to flow from the first container to the rotor and plasma to flow from the rotor to the first container;
• valve means for directing flow between the venous-access means, the rotor, the first and second containers, the valve means connected
• to the rotor by a common tube,
• to the first container by a first-container tube, the first-container tube in direct fluid communication with the venous-access means.
• and to the second container by a second-container tube;
• a controller for controlling the spinning means and the valve means;
• and
• an interlock device, connected to the controller, wherein the controller does not permit flow from the rotor until the venous-access means has been inserted into the interlock device.

• and to the second container by a second-container tube;
• pumping means for urging flow from the rotor, the pumping means controlled by the controller to start pumping after the rotor has been spun sufficiently to separate the plasma and red blood cells;
• and
• a controller for controlling the spinning means and the valve means, wherein the controller does not permit the pumping means to urge flow from the rotor until the venous-access means has been inserted into an interlock device.

A system for collecting and processing blood from a donor, the system comprising:

• a disposable collection system including venous-access means, a centrifuge rotor for receiving the blood, a first container, and tubing connecting the venous-access means, the rotor, and the first container;
• an interlock device for preventing activation of the pumping means until the venous-access means is inserted into the interlock device;
• pumping means operably connected to the rotor for urging flow from the rotor,
• a control apparatus for receiving the rotor, the control apparatus including means for spinning the rotor so as to cause the separation of the blood into plasma and red blood cells,
• wherein the first container stores both an anticoagulant and the separated plasma, and the tubing permits the anticoagulant to flow from the first container to the rotor and the separated plasma to flow from the rotor to the first container, and wherein the the rotor includes an elastic diaphragm mounted on a rigid mounting member, the diaphragm and the mounting member defining a chamber of varying volume for containing the blood.
