Abstract: Fluid access devices include a machine-side hydraulic circuit and a patient-side hydraulic circuit, and are configurable between a connected state and at least one disconnected state. In the connected state, fluid flows between the machine-side hydraulic circuit and the patient-side hydraulic circuit. In the disconnected state, fluid does not flow between the machine-side hydraulic circuit and the patient-side hydraulic circuit. In some disconnected states, fluid recirculates through at least one of the machine-side hydraulic circuit or the patient-side hydraulic circuit in the disconnected state.

Abstract: Portable hemodialysis systems include a dialysis fluid module configured to regenerate a dialysis fluid, and a blood handling module reversibly fluidically couplable to the dialysis fluid module. The portable hemodialysis system is configured to dialyze blood in the blood handling module using the dialysis fluid regenerated by the dialysis fluid module.
