Control of fluid flow during priming of a fluid flow circuit
A fluid processing system includes a fluid processing device and a fluid flow circuit. The device includes a pump configured to convey a priming fluid through the circuit. The pressure in a conduit of the circuit is measured while the pump is operated at a particular rate. When the magnitude of the pressure is less than the magnitude of a predetermined pressure at the end of a time interval, the pump is operated at an increased rate. When the magnitude of the pressure is greater than the magnitude of the predetermined pressure at the end of the time interval, the pump is instead operated at a decreased rate. The magnitude of the pressure in the conduit is again compared to the magnitude of the predetermined pressure after the pump has operated at the increased or decreased rate for the time interval to determine how to next adjust the operational rate.
Automated Sequential Incubations During Fluid Processing
A fluid processing method and an associated system are provided. The fluid processing method includes a first and second incubation stage which are performed sequentially without any intermediate steps. The fluid processing method creates a second incubation fluid product from a biological fluid.
