Abstract
A pheresis process and apparatus for carrying it out. Blood from a donor is transferred to a pheresis bowl formed to have a red cell reservoir and a plasma reservoir in fluid communication through plasma ducts. The pheresis bowl is adapted for centrifuging to separate the red cells and plasma. This separation is accomplished simultaneously with the withdrawal of blood from the donor. At the end of the withdrawal the red cells are returned to the donor. The connection with the donor is thus continuously maintained during the entire procedure. The process is safe, fast and economical.
