    Abstract: A plasmapheresis system and a method for operating a plasmapheresis system are provided by which a volume of plasma product (i.e., anticoagulated plasma) so that that the targeted volume of pure plasma in the plasma product is determined based on donor-specific characteristics. In particular, the targeted amount of pure plasma to be collected is based on the weight, or the weight and the height, of the donor. The targeted volume of pure plasma to be collected, TVP, may be a multiple of the donor's weight. Alternatively, TVP may be a multiple of the donor's total blood volume, TBV, with the TBV of the donor being determined based on the donor's weight and height. A target volume for the plasma product to be collected, TVPP, is established, and separation of whole blood into a plasma component and a second component continues until the volume of plasma product in a collection container equals TVPP.

    Abstract: A fluid separation device includes a centrifuge in which a fluid is separated into at least two components, with an interface therebetween. At least a portion of one of the separated fluid components is removed from the centrifuge and flows through a vessel. Light is reflected off of the separated fluid component in the vessel and received and analyzed to determine its main wavelength. If the main wavelength is higher than a maximum value, a target location of the interface is changed. If the main wavelength is less than the maximum value, then the location of the interface is compared to the target location. When the interface is sufficiently close to the target location, the optical density of the separated fluid component in the vessel is compared to a minimum value. If the optical density is less than the minimum value, the target location of the interface is changed.

    Abstract: A system and method processes blood donation data for presentation on an operator interface. A handheld computing device has a touch screen display and a processing circuit to provide an icon associated with an executable application on a first display screen, the icon configured to be positioned along with icons for other executable applications on the first display screen. The processing circuit is to retrieve an indication of a need for a particular blood component, wherein the particular blood component is selected from the group comprising whole blood, double red cells and plasma. The processing circuit is to provide the indication of the need for a particular blood component to the display. The processing circuit is to provide to the touch screen display a remaining time or a date the blood donor is next eligible to donate a blood component based on a donation eligibility guideline.

    Abstract: A membrane separation device is disclosed along with systems and methods employing the device in blood processing procedures. In one embodiment, a spinning membrane separator is provided in which at least two zones or regions are created in the gap between the spinning membrane and the shell, such that mixing of the fluid between the two regions is inhibited by a radial rib or ridge associated with the spinning membrane that decreases the gap between the spinning membrane and the shell to define two fluid regions, the ridge isolating the fluid in the two regions to minimize mixing between the two. Automated systems and methods are disclosed for separating a unit of previously-collected whole blood into selected blood components, such as concentrated red cells and plasma, for collecting red cells and plasma directly from a donor in a single pass, and for cell washing. Data management systems and methods and priming methods are also disclosed.
