Abstract: A modular serviceability sled includes a frame, subassembly, interconnection, gasket, and shielding component. The interconnection is operatively connected to the subassembly and includes an electrical, pneumatic, and/or hydraulic connection. The gasket can engage the frame and a base assembly of an apparatus. The shielding component can contact the frame and the base assembly and includes an electromagnetic interference and/or radio frequency shielding component. The sled is movable between an engaged state and a disengaged state. In the engaged state, the sled is at least partially within a receiving space of the apparatus, the gasket engages the frame and the base assembly, the shielding component contacts the frame and the base assembly, and the interconnection is operatively connected to a machine interconnection of the apparatus. In the disengaged state, the interconnection is disconnected from the machine interconnection and the sled is configured to freely move with respect to the base assembly.

Abstract: An apheresis system at least partially defines a chamber and includes centrifuge that is movable between lock and unlock states. The centrifuge includes a base, cover, lock assembly, and latch assembly. The cover engages the base and defines slots. The lock assembly is coupled to the base and rotates between latched and unlatched states. The lock assembly includes tabs and a protrusion. The tabs are in the slots of the cover. The protrusion at least partially defines a receptacle. The latch assembly is coupled to the base and includes a lever and engagement component attached thereto. In the latched state, the protrusion engages the engagement component to reduce or prevent rotation of the lock assembly. In the unlatched state, the lock assembly can rotate. In the lock state, the tabs are at least partially within the slots. In the unlock state, the cover is movable with respect to the base.

Abstract: A method includes detecting a condition including one or more of a change in flow of a fluid and a change in a composition of the fluid, issuing an alarm in response to the condition detected, lowering a flow rate; and attempting to restart process and increase the flow rate. The change in flow may include a change in pressure. The change in flow may be associated with a collapsed vein. The change in flow of the fluid may include detecting that the flow rate has fallen below a threshold. The change in the composition may be associated with a color. The change in the composition may include using a color sensor to detect one or more of a red, a green, and a blue reflection or transmission to detect red blood cells.

Abstract: A pump for fluids includes a rotor sub-assembly, a tubing pressure block, an inlet guide, an outlet guide, and a tubing guard. The rotor sub-assembly includes at least one roller. The tubing pressure block includes a raceway and at least one projection. The tubing pressure block is movable between a first position and a second position. The inlet guide includes an inlet tubing channel and is disposed proximate to a first side of the tubing pressure block. The outlet guide includes an outlet tubing channel and is disposed proximate to a second side of the tubing pressure block. The tubing guard is configured to engage with the inlet guide and the outlet guide when the tubing guard is in a closed position and is configured to expose the rotor sub-assembly, the tubing pressure block, the inlet guide, and the outlet guide when in an open position.

Abstract: A bag loader for loading and unloading at least one satellite bag into and from the central compartment of a rotor of an apparatus for separating a composite liquid into at least two components comprises an upper part for removably securing an upper portion of at least one satellite bag; a lower part comprising a receptacle; and an intermediate part connecting the upper part to the lower part and exposing an intermediate portion of a satellite bag.

Abstract: An apparatus for separating blood into blood components using a separation vessel satellite bags mounted on a centrifuge rotor and a balancing assembly for the centrifuge to compensate for changes to the center of gravity.
