Abstract: Embodiments disclosed herein provide a compression system including a squeeze plate, a linkage assembly, and a drive assembly. The squeeze plate is configured to engage with a fluid bag. The linkage assembly comprises a plurality of brackets each coupled to a plurality of linkage sets, where actuation of the linkage assembly causes lateral translation of the squeeze plate. The drive assembly comprises a lead screw disposed through each of the plurality of brackets, an actuator configured to rotate the lead screw to actuate the drive assembly, and a nut assembly coupled to the lead screw and at least one of the plurality of brackets, where the nut assembly is configured to provide a biasing force to maintain a target range of pressure on the fluid bag if the actuator fails.
