Abstract: 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.

Abstract: A blood processing system includes a centrifuge and an optical monitoring system mounted at a stationary radial position with respect to the centrifuge. A flow circuit may be mounted within the centrifuge, with an umbilicus of the flow circuit extending outside of the centrifuge. A midsection of the umbilicus is orbited around a rotational axis of the centrifuge at a uniform first speed, which causes the centrifuge to rotate at a non-uniform second speed that is approximately double the first speed. The monitoring system is configured to view the flow circuit through a radial window of the centrifuge to determine a characteristic of the flow circuit. The yoke and/or umbilicus may occasionally move into position between the monitoring system and the window, so a controller of the monitoring system is configured to determine when unobstructed light reflected through the window by the centrifuge is received by the monitoring system.

Abstract: Systems, methods, apparatus, and computer readable media are provided for disposable component authentication with respect to a biological fluid processing device instrument. An example instrument authentication system includes a computer facilitating configuration and operation of the biological fluid processing instrument using a disposable component. A first interface is provided by the computer and is used by a service technician to configure the biological fluid processing instrument for a number of disposable components and to provide a service technician with a validation code. A key generator is to accept the validation code from the service technician and generate an authentication key in response to the entered validation code. A second interface is provided by the computer, the second interface prompting the service technician to enter an authentication key, wherein the authentication key authorizes use of a certain number of disposable components for the biological fluid processing instrument.
