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.
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.
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.
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.
