A flexible container intended to be used to facilitate blood processing via blood washing and/or centrifugation (e.g., cryoprecipitation) to achieve separation of blood components [e.g., red blood cells (RBCs), platelets, plasma], typically to generate a blood product from autologous or donor blood for procedural (e.g., surgical haemostasis) or transfusion applications [e.g., fibrinogen rich cryoprecipitate]. It is additionally intended to be used as a blood storage bag, and is made of flexible durable materials that withstand centrifugation and freezing/thawing. This is a single-use device.
