Abstract
A pneumatic pump manifold disposable system, configured as a cassette, is used for the purpose of red cell and plasma apheresis. The cassette integrates a separation device, manifold system, macro-aggregate filter, and five pumping chambers for the purpose of separating plasma and red cells from the whole blood. The cassette system, with the separation device directly attached without tubing, simplifies the loading of the disposable set into the hardware, and reduces the manufacturing complexity of the set. The system allows for plasma, plasma and red cells, or just red cells to be stored in long term storage containers after a procedure.
