The control device operates the withdrawing device and the separating device in cycles One of the cycles comprising operation of the pump to withdraw, through the phlebotomy needle, an amount of blood from the donor and its provision to the separating device. which separates the withdrawn blood into the number of components., of the selected blood component is then collected from the separating device. Blood components remaining in the separating device is returned to the donor USE/ADVANTAGE : For separating whole blood into components. Convenient, safe and effective approach to blood apheresis.
