Abstract: The present disclosure includes systems and methods for hemodialysis, such as including a first dialysis module and an auxiliary module detachably connectable to the first dialysis module. The first dialysis module can include a dialyzer, a blood circuit, a dialysate circuit, and a sorbent. The auxiliary module can include an ultrafiltrate collector operably couplable to the dialysate circuit for removing excess fluid therefrom.

Abstract: In one aspect, a method and system for detecting a change in fluid dynamics of a fluid flowing through an extra-corporeal circuit is disclosed, which includes establishing an acoustic wave resonance across a transverse dimension of at least a portion of a line associated with the extra-corporeal circuit through which the fluid flows, monitoring a phase signal of the resonant acoustic wave, and identifying occurrence of a change in fluid dynamics of the flowing fluid when the observed phase signal of the resonant acoustic wave indicates a deviation from the expected fluid flow signature. The change in fluid dynamics can be used to indicate a venous needle dislodgement event.

Abstract: The disclosed subject matter relates to extracorporeal blood processing or other processing of fluids. Volumetric fluid balance, a required element of many such processes, may be achieved with multiple pumps or other proportioning or balancing devices which are to some extent independent of each other. This need may arise in treatments that involve multiple fluids. Safe and secure mechanisms to ensure fluid balance in such systems are described.
