Abstract
A centrifuge with an associated container system in the form of cassettes for separation and/or treatment of blood or blood components. The centrifuge comprises a rotor having a central compartment in the form of a tubular shaft cavity extending concentrically with the axis of rotation of the rotor and an annular separation compartment which is arranged around said cavity at the upper part thereof. A first container system arranged in the rotor for washing of blood cells comprises a round bag with two or more flexible secondary containers connected thereto, of which at least one contains a treatment liquid, and a tubular sleeve adapted to the shaft cavity of the rotor. The secondary containers stand in the sleeve resting against each other, and the round bag is mounted on a projecting flange at the upper part of the sleeve. A second container system arranged in the rotor for separation of a thrombocyte suspension differs from the first in that the sleeve has a smaller diameter than the shaft cavity of the rotor and is adapted to be centered in the center of the cavity. An initially empty secondary container for receiving the separated components from the round bag is arranged in th…
