The weigh scale includes a load cell, a bracket secured to the load cell, and a container support clip secured to a connection shaft. The upper end of the connection shaft is configured to be received in the bracket so as to permit the container support clip to self-center with respect to the bracket.

Systems for retaining and weighing variously configured containers

A fluid processing device includes a detection assembly having a source and a detector. The source emits a signal to fluid or a fluid component in the fluid processing device, with at least a portion of the signal reaching the detector. The detection assembly further includes one or more adjustment systems configured to adjust the position and/or orientation of one or more components of the detection assembly. The position and/or orientation of the entire source and/or the entire detector, the position and/or orientation of a component of the source with respect to another component of the source, and/or the position and/or orientation of a component of the detector with respect to another component of the detector may be adjusted to increase the signal received by the detector.

A centrifuge rotor assembly includes a chamber assembly, a bearing support, and a counterweight that is substantially diametrically opposed to the bearing support with respect to the chamber assembly. The chamber assembly receives a processing chamber of a fluid circuit, while the bearing support receives a portion of an umbilicus that is fluidly connected to the processing chamber. The bearing support and counterweight are rotated about a central axis of the chamber assembly by an electric drive of the centrifuge rotor assembly, with the bearing support and counterweight remaining substantially diametrically opposed to each other with respect to the chamber assembly while being rotated about the central axis. The electric drive may rotate the bearing support and counterweight at a plurality of different speeds, with the counterweight automatically moving with respect to the bearing support between radially innermost and radially outermost positions to balance the centrifuge rotor assembly.

A cassette holder includes an actuator assembly and a cassette plate. The actuator assembly includes an actuator (e.g., a valve actuator or a sensing actuator) and a shaft, with the shaft including a head, a base, and a perimeter groove defined between the head and the base. The cassette plate includes an opening aligned with the actuator and a keyhole at least partially aligned with the shaft. The keyhole is associated with a channel of the cassette plate, which is configured to receive at least a portion of a lever. The lever is movable between a locked position (in which the lever is primarily positioned within the channel) preventing removal of the shaft from the keyhole and an unlocked position (in which the lever is primarily positioned outside of the channel) allowing for removal of the shaft from the keyhole.

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.

Stationary optical monitoring system for blood processing system

A fluid processing cassette and sensor coupling system is disclosed, comprising a cassette comprising a cap having an opening formed by an inner cylindrical wall having a first diameter, an outer cylindrical wall having a second diameter, and a contact surface connecting the inner and outer cylindrical walls.
