ABSTRACT:
A device for obtaining from at least two spatially separated areas the heterogeneous components of a liquid, especially stabilized whole blood in a flexible and transparent bag with at least one line leading out of it. The device consists of a front plate that is part of a housing, of a pressure-application plate that pivots toward the front plate, of a drive mechanism, and of a sensor. The point that the pressure-application plate pivots around is below the bag and at the point of intersection between the surfaces of the plates, specifically at least 30% of the length of the pressure-application plate away, and the drive mechanism engages a lever that is rigidly secured to the pressure-application plate. A bag employed in conjunction with the device has an intake line at the top and an outlet line and a filling and blood-collecting tube at the bottom, only one bag-to-bag transport system at the top, and no outlet connections.
