Blood processing systems and methods establish on line communication between a container and a source of blood containing leukocytes and platelets, such as a human donor. The systems and methods create a centrifugal field between the source of blood and the container that separates from the blood an unfinished suspension of platelets having a first physiologic characteristic different than the desired physiologic characteristic. The systems and methods pump the unfinished platelet suspension outside the centrifugal field through a finishing device. The finishing device changes the first physiologic characteristic to the desired physiological characteristic, thereby creating the finished platelet suspension. The systems and methods convey the finished platelet suspension from the finishing device directly into the container. The systems and methods function without interrupting the on line communication between the container and the source of blood.

The invention discloses a wave simulation generating device under a high gravity field. The adoption of a wave absorbing unit can enhance the wave absorbing effect, reduce the influence of a reflectedwave on a waveform, and ensure the similarity of a wave simulation experiment to real environment simulation. The wave absorbing unit can adjust the position of a wave absorbing plate and the size ofa grating opening according to the waveform generated by a wave generating unit so as to ensure an optimal wave absorbing effect. The wave generating unit realizes force transfer and the decoupling of motion in a simple structure. Compared with a transmission structure with a long transmission path and a complicated structure, the wave simulation generating device is less affected by mechanism jamming caused by deformation of a centrifugal field and ensures the rigidity and stability of a transmission mechanism more easily. Different from a conventional way of moving a push plate as a whole,only the upper part of the push plate is pushed, and so the load on the push plate is small and required power is small. The wave simulation generating device under a high gravity field is suitable for simulation of waves with high water depth and large amplitude.

The invention discloses a system and a method for accurate positioning control under the overweight environment. The system for accurate positioning control comprises a driving unit, an industrial personal computer, a magnetic grid sensor and a motion controller, wherein the driving unit comprises a servo motor, a servo actuator and a rotary transformer. When the span of a controlled moving support is small, one set of driving unit is used for performing single-axis positioning control on the controlled moving support; and when the span of a moved support is overlarge, two sets of driving units are adopted for synchronously driving two sides of the controlled moving support to perform double-axis positioning control. The system is high in positioning accuracy and repeatability precision, has large loading capacity and is suitable for accurate positioning of the large-range controlled moving support under the overweight environment. Under a 100g of centrifugal field, the positioning accuracy of the system is superior to 0.2mm, and the largest bearing force exceeds 18000N. For achieving double-axis positioning control under the high centrifugal field, two axes are regarded as the same axis for performing synchronous control, and reliability and safety of the system are improved.

A single use, sterile, self-contained, compact, easy to use centrifugal separation unit provides for quick, reliable platelet concentration from whole blood. Anti-coagulated blood is injected through an elastomeric seal into a separation chamber featuring a tapered barrel and an end cap. At least one port is located in the end cap, at a desired radius from the longitudinal axis. The centrifugal field created by rotation of the chamber stratifies the blood radially, with red blood cells adjacent the wall of the barrel, and plasma found closest to the longitudinal axis. Opening the port causes the pressure of the centrifugal field to eject red blood cells or plasma, thereby increasing the concentration of platelets remaining in the chamber. After ceasing chamber rotation, the concentrated platelets are recovered.
