    摘要： A packaging tray for use in a blood processing system including a blood processing device having device components arranged on a component surface and a removable fluid flow circuit having circuit components configured to interact with corresponding device components, wherein the packaging tray configured to be selectively arranged on and removable from the component surface. The packaging tray includes a first surface and a second surface opposite to the first surface and spaced apart by a thickness, component sections arranged at positions corresponding to positions of respective device components, the component sections respectively formed, at least partially, as openings extending through the thickness, and a plurality of recessed pathways formed on the first surface, the recessed pathways extending between the component sections. A blood processing device may include the packaging tray, and a blood processing system may include a blood processing device and the packaging tray.

    摘要： A plasmapheresis system and a method for operating a plasmapheresis system are provided by which the reservoir for the concentrated red blood cells (RCC) has a first chamber for receiving anticoagulant used for priming the separator and purging the system of air prior to the initial draw cycle and a second chamber for receiving separated red blood cells. Because the entire volume of second chamber of the RCC reservoir may now receive separated red blood cells and no AC prime volume, a greater amount of whole blood may be processed in the first draw cycle, thus resulting in a greater total volume of Immunoglobulin G (IgG) being collected during the plasmapheresis procedure.

    摘要： During a first stage of a priming procedure, a priming fluid is conveyed into a spinning membrane separator via a filtrate outlet port so as to convey air out of the spinning membrane separator via an inlet port and a retentate outlet port of the spinning membrane separator. During an optional second stage of the priming procedure, the priming fluid is conveyed into the spinning membrane separator via the inlet port so as to convey air out of the spinning membrane separator via the retentate outlet port. A rotor positioned within a housing of the spinning membrane separator may be rotated with respect to the housing during the first and second stages to force air from within the rotor into an annulus defined between the rotor and the housing for more complete priming of the spinning membrane separator.

    摘要： A blood processing device includes a pump system, a valve system, a centrifuge, and a controller configured and/or programmed to control the operation of the pump system, the valve system, and the centrifuge to execute a blood separation procedure. The blood separation procedure executed by the controller includes pumping blood into the centrifuge, separating the blood in the centrifuge into red blood cells and plasma, and collecting portions of the separated red blood cells and plasma. Subsequently, a portion of the collected red blood cells is pumped back into the centrifuge to collect an additional amount of the separated plasma. A buffy coat or white blood cell layer may be formed between the separated red blood cells and plasma in the centrifuge. If so, a portion of the collected plasma may be pumped back into the centrifuge to harvest the buffy coat or white blood cell layer.
