ABSTRACT:
A pressure plate blood processing centrifuge apparatus is described. A plate is disposed adjacent a flexible bag in which blood is being processed. Under the influence of centrifugal force the plate, which is disposed inwardly nearer the center of rotation than the bag, expels a separated blood component from the bag into a receiver container. The container may be located (1) radially inward or (2) radially outward from the bag or (3) adjacent and equidistant from the center of rotation.
In the embodiment in which the container is located radially outward from the bag, a valve is provided which is responsive to the specific density of separated components to stop the flow. In other embodiments, the mass of the plate is selected so as to expel only the desired component. A plurality of alternate embodiments are described which make the apparatus useful for a variety of apparatus, such as plasma pheresis, platelet pheresis and cell-washing.
