<p>The invention refers to an arrangement for blood separators which transfers blood components from a primary bag (4) comprising centrifuged blood forming part of a set of bags to at least two secondary bags (8, 9) forming part of the same set of bags. The blood separator is of the type which by means of a presser arrangement acting on the primary bag transfers the blood components via tubes being possible to seal off by means of valves controlled from a microprocessor. The arrangement makes it possible to transfer a predefined quantity of one or several blood components to preferably one of the secondary bags (9). The arrangement comprises a common balance (14) arranged preferably on one of the side walls (10) of the blood separator (1) hanging on a shaft (13) fixed on the side wall (10). The balance is provided with a pin (12) for hanging of that secondary bag (9) in which the predefined quantity of blood component is intended to be filled and has additionally an adjustable counterweight (15) and a reflective surface arranged at the backside of the balance delimited by means of an edge (16) which is directed radially relative to the shaft which surfacecooperates with an optical sensor (17) in the side wall (10) connected to the microprocessor which sensor controls the valve (23) which in its turn controls the liquid flow to the secondary bag (9), hung on the balance (14) via the processor in such a way that the valve (23) stops the liquid flow to the bag (9) when the weight of the quantity of blood component has been reached.</p> |
