A mains electricity (AC-powered) device designed for the automated separation of whole blood or previously centrifuged blood into components [e.g., red blood cells (RBCs), platelets, leukocytes] for further processing or storage. It is a programmable device with a user interface that uses a mechanical separation method (e.g., pressure plates, microfluidics) to transfer the blood component(s) from the donor bag into a removable disposable receptacle. It may have additional features such as sensors, scales, and an automatic mechanism for opening the valve(s) on the donor bag. It is typically used in a blood bank or transfusion centre, and is not donor or patient connected.
