A dialysis system is configured to enable a patient to undergo both peritoneal dialysis and extracorporeal blood treatments. The example dialysis system includes a base unit configurable to provide a first fluid for use in preforming at least one peritoneal dialysis treatment at a first time. The base unit is further configurable to provide a second, different fluid for use in at least one extracorporeal blood treatment at a second, different time. The example dialysis system also includes a blood treatment unit configured to be docked to the base unit. The blood treatment unit includes a blood pump configured to pump blood from the patient to a blood filter and from the blood filter back to the patient. The blood filter or a blood line in communication with the blood filter receives the second fluid from the base unit for use in the at least one extracorporeal blood treatment.

An extracorporeal and drug delivery system includes (i) a renal failure therapy machine operable with a blood filter in fluid communication with an arterial line and a venous line, the machine including (a) an effluent pump for pumping effluent from the blood filter at an effluent flowrate, and at least one of (b) a dialysis fluid pump for pumping dialysis fluid to the blood filter at a dialysis fluid flowrate, (c) a predilution pump for pumping replacement fluid into the arterial line at a predilution flowrate, or (d) a postdilution pump for pumping replacement fluid into the venous line at a postdilution flowrate; (ii) an infusion pump operable to deliver an intravenous (“IV”) drug to the patient at an IV drug flowrate; and (iii) a coordinating logic implementor configured to adjust the IV drug flowrate based on an amount of the IV drug removed via the effluent flowrate.

A system for monitoring percentage change in blood volume (ΔBV %) during dialysis treatment includes a sensor device configured to obtain hematocrit (Hct)-related measurements based on detecting light which has passed through extracorporeal blood of a patient undergoing the dialysis treatment; one or more controllers configured to: determine Hct values based on the Hct-related measurements obtained by the sensor device; determine ΔBV % values based on the determined Hct values; and generate a GUI having a ΔBV % plot based on the determined ΔBV % values; and a display device having a display configured to display the GUI having the ΔBV % plot. Zone indicators are provided on the display to distinguish between a first zone corresponding to a first ΔBV % profile, a second zone corresponding to a second ΔBV % profile, and a third zone corresponding to a third ΔBV % profile.

A blood component collection system, which is one form of a biological component collection system, is equipped with a centrifugal separation device and a biological component collection device. The biological component collection device comprises a pressed soft portion pressed by a load detecting unit. The centrifugal separation device includes a collection and returning pump, and a control unit having an internal pressure computation unit which calculates a circuit internal pressure of the biological component collection device on the basis of a detection value of the load detecting unit. The internal pressure computation unit performs a zero reset process of setting a pressure value corresponding to the detection value of the load detecting unit, so as to become zero at each instance of a predetermined timing at which the collection and returning pump is stopped.
