An annular seal part is formed at which an entire circumference that is adjacent to a peripheral portion of the filter member is integrally sealed to the flexible container. The blood processing filter is retained in a curved shape that curves as viewed from a predetermined one direction that is orthogonal to the thickness direction by the rigidity of the seal part. | 06-28-2012 |
20120252650 | CENTRIFUGE - Centrifuges are useful to, among other things, remove red blood cells from whole blood and retain platelets and other factors in a reduced volume of plasma. Platelet rich plasma (PRP) and or platelet poor plasma (PPP) can be obtained rapidly and is ready for immediate injection into the host. Embodiments may include valves, operated manually or automatically, to open ports that discharge the excess red blood cells and the excess plasma into separate receivers while retaining the platelets and other factors in the centrifuge chamber. High speeds used allow simple and small embodiments to be used at the patient's side during surgical procedures. The embodiments can also be used for the separation of liquids or slurries in other fields such as, for example, the separation of pigments or lubricants. | 10-04-2012 |
