Centrifuge comprising a blood bag system with an upper and lower outlet

The invention relates to a centrifuge provided with a blood bag system having an upper and lower outlet for separation of blood constituents, containing a rotor which can be driven in a rotative manner about a hub, wherein at least one conventional whole blood bag equipped with an upper outlet and with a lower outlet can be positioned vertically in this blood bag, while the whole blood bag can be arranged on the rotor in such a way that one outlet of the whole blood bag is bent in a radial direction, and the opposite outlet of the whole blood bag is bent in the other radial direction, so that the entire whole blood bag and the outlets thereof adopt an approximately Z- or S-shaped form in its functional position. In this case it is preferred that the upper outlet of the whole blood bag lie radially toward the interior and the lower outlet of the whole blood bag lie radially toward the exterior of the whole blood bag. The whole blood bag is held in an insert, and the insert is in its turn held by an approximately sector-shaped cartridge, wherein a plurality of such cartridges is uniformly distributed by being arranged around the circumference of the rotor. One advantage of the centrifuge is that conventional blood bags can be used and recovery of individual blood constituents (plasma, erythrocytes, buffycoat) can be achieved with a significantly higher degree of efficiency and functionality, and with a high degree of purity.

Blood bag labels and the like

A label for a blood bag comprising a microporous plastic film including a matrix of interconnected pores for allowing gas to flow into and out of the blood bag through a labeled area. The pores allow ink to be absorbed at least on an outer surface of the label allowing the label to be printed and/or written on. The labels of the present invention have breathability with respect to gas that is similar to paper. However, the label is more durable than a paper label in that it can tolerate moisture, abrasion, temperature extremes, dimensional changes, and the like. Accordingly, the labels do not crack or wrinkle as easily as paper labels.

Blood bag system

The invention is directed to a blood bag system for blood products comprising a bag (3) and at least one tubing (11) connected thereto, the system being made of at least partly transparent plastics material, wherein photoactive substances (31) may be enclosed in a closed-off section (A) of the tubing (11) of the ready-for-use system, which may be handled individually as an independent unit. Every blood bag system of this kind is adapted to be combined with another blood bag system, which may comprise one or several bags (3 5 7 9) and may likewise be handled as an independent unit, by interconnecting both systems.

Bottom blood bag separation system

Plastic blood bag system including a bag having a generally longitudinal seal extending from the top of the bag and between two blood bag ports downwardly to at least the lower half of the bag but not to the bottom of the bag, thereby leaving the sole passageway within the bag and between two ports located in the lower half of the bag. The longitudinal seal terminates proximal to the central axis of the bag with a spot weld to prevent tear. In addition, the cross-sectional diameter of the channel increases as the channel nears the central axis.
