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.

Device for separating the components of a liquid, especially whole blood

An aqueous solution for suspending and storing cells, especially erythrocytes, and containing sodium chloride, glucose or fructose, adenine, and a sugar alcohol, the sugar alcohol being sorbitol or xylitol is employed to further improve the storage time and hence the survival rate of the cells and even reduce the hemolysis rate of erythrocytes in packed red blood cells.

Aqueous solution for suspending and storing cells, especially erthrocytes

A bag suitable for the storage, deep-freezing and transfusion of blood and blood components formed of a calendered or extruded foil of plasticizer-free polyurethane of a thickness of about 0.1-0.5 mm, a Shore hardness A of about 60-85, temperature resistance up to about 160.degree. C. and down to about -196.degree. C. without change of properties. The bag can be used in combination with fittings and tubings of the same material to provide an overall plasticizer-free polyurethane system. The bag can be sterilized, is capable of low temperature storage, and exhibits other desirable properties without affecting the quality of its contents.
