Abstract
Described are embodiments that include methods and devices for separating components from multi-component fluids. Embodiments may involve use of separation vessels and movement of components into and out of separation vessels through ports. Embodiments may involve the separation of plasma from whole blood. Also described are embodiments that include methods and devices for positioning portions, e.g., loops, of disposables in medical devices. Embodiments may involve use of surfaces for automatically guiding loops to position them into a predetermined position.
Claims21
A method for collecting a blood component through apheresis, the method comprising:
- determining a target volume of a first blood component;
- drawing whole blood from a donor into a centrifuge, wherein the determining the target volume of the first blood component occurs prior to the drawing whole blood;
- adding an anticoagulant into the whole blood from an anticoagulant source;
- spinning the centrifuge at a first speed to separate the whole blood into the first blood component and a second blood component;
- directing the first blood component into a container;
- and
- returning at least the second blood component from the centrifuge and back into the donor.
