Abstract: A dialysis system includes a sorbent device positioned along a fluid circuit for regenerating dialysate during a dialysis treatment carried out at the dialysis system, a filter coupled to an outlet of the sorbent device such the any fluid flowing through the sorbent device must first flow through the filter before reentering the fluid circuit, and a pump positioned downstream of the filter along the fluid circuit. The pump is operable between first and second dialysis treatments carried out at the dialysis system to circulate a fluid through the sorbent device to prevent matter within the sorbent device from solidifying and circulate the fluid through the filter to remove contaminants from the fluid.

Abstract: A method of preserving a sorbent device of a dialysis system, the method comprising—after administering a first dialysis treatment at the dialysis system and before administering a second dialysis treatment at the dialysis system—circulating a fluid through the sorbent device to prevent matter within the sorbent device from solidifying and circulating the fluid through a filter coupled to an outlet of the sorbent device to remove contaminants from the fluid.

Abstract: A tubing connection system is disclosed by which patients or others seeking to make connections between tubing sets, particularly for a home dialysis machine, can make those connections without having to hold each tube in each hand. In various implementations, the tubing connection device may include mechanisms for rectilinear and rotational motion to engage tubing connectors for connection between the tubing connectors as well as torque control features to prevent over-tightening. The system may also include automatically controlled gripping mechanisms to facilitate gripping of the tubing in connection with tubing connection operations. The system provides for facilitating a consistently secure connection of the tubing connectors.
