<p>The invention relates to a method for separating blood into blood components and to apparatus for removing blood components from a blood container which has at least one outlet opening. The method comprises introducing blood into a blood container which has at least one outlet opening in the upper limit of the container, centrifuging the blood container in a relatively high centrifugal field to form three mutually superimposed component layers, applying pressure to the blood container to remove the upper component through the outlet opening and, during or after this pressure stage, forming in the blood container a channel through which a second component is connected with the outlet opening or with a second outlet opening, and then applying further pressure to remove the second component through the channel formed. The apparatus for removing centrifuged and stratified blood components from a blood container (1a) having at least one outlet opening includes a housing (16) which has mounted therein a first and a second pressure plate (3, 2) which are movable in relation to one another, a suspension means (50) by means of which the blood container (1a) can be positioned between the pressure plates (3, 2), and means for achieving relative movement of the pressure plates. The apparatus also includes a mandrel (5) in the second pressure plate (2) which is operative in forming a channel in the container (1a) as the blood container (1a) is compressed to remove the uppermost blood component, this channel connecting a blood container outlet opening with the bottom blood component and being formed only when the upper component has been removed from the blood container.</p> |
