A dialysis system includes a dialysis machine configured to control fluid loss or ultrafiltration (UF) volume over a treatment; a graphical user interface (GUI) that allows selection of a prescription entry for the treatment; and a processor operating with the GUI, the processor programmed to (i) receive a plurality of prescription entries via a local or wide area mode of data communication, each prescription entry including at least one prescribed parameter for operating the dialysis machine to control the fluid loss or UF volume, and (ii) enable an operator to choose between the prescription entries provided at the GUI, and select one of the prescription entries for the treatment.

A dialysis system includes a fresh dialysis fluid pump, a used dialysis fluid pump, a fresh fluid flow path, a used fluid flow path, and a dialysis fluid cassette carrying a balance chamber, the balance chamber including a first rigid portion, a second rigid portion, and a flexible sheet located between the first and second rigid portions, the flexible sheet dividing the balance chamber into (i) a fresh dialysis fluid compartment connected fluidly to the fresh dialysis fluid pump via the fresh fluid flow path, wherein fresh dialysis fluid contacts the first rigid portion and a first side of the flexible sheet, and (ii) a used dialysis fluid compartment connected fluidly to the used dialysis fluid pump via the used fluid flow path, wherein used dialysis fluid contacts the second rigid portion and a second side of the flexible sheet.

A hemodialysis system comprising: a source of priming fluid; an extracorporeal circuit including an arterial line, a venous line, and a drip chamber; a level sensor operable with the drip chamber; a reversible blood pump operable with the extracorporeal circuit; a connection between the arterial and the venous line; and a priming sequence in which priming fluid from the source is pumped in a reverse pump direction through the extracorporeal circuit and reversibly in a normal pump direction through the extracorporeal circuit, wherein an output from the level sensor is used to determine when to stop pumping in at least one of the directions.

An extracorporeal blood filtering machine can include a blood circuit, an effluent circuit, and a source fluid circuit and can be controlled by a controller. The extracorporeal blood filtering machine can also include access ports for connecting the source fluid circuit to the blood circuit, as well as blood sensors to detect possible issues with the extracorporeal blood filtering machine. The extracorporeal blood filtering machine can include density sensors and flow sensors that enable it to be more accurate and to operate while being transported. The extracorporeal blood filtering machine can further include a user interface and can display fluid inflow/outflow information. A medical fluid container can automatically empty after being filled. An apparatus for supporting a medical fluid container can include a hanger and an attachment member with the apparatus able to adjust to ensure the medical fluid container remains properly oriented directly under a medical fluid container scale.

A dialysis system includes a dialysis fluid cassette-based membrane blood pump; a dialyzer in fluid communication with the blood pump; first and second dialysis fluid cassette-based balance chambers each having (i) a fresh dialysis fluid compartment in fluid communication with the dialyzer and (ii) a spent dialysis fluid compartment; a dialysis fluid cassette-based fresh dialysis fluid membrane pump in fluid communication with the fresh dialysis fluid compartments of the first and second balance chambers; a dialysis fluid cassette-based spent dialysis fluid membrane pump in fluid communication with the dialyzer and the spent dialysis fluid compartments of the first and second balance chambers; and arterial and venous lines in fluid communication with the dialyzer for patient connection, the arterial and venous lines each including a contact used for electrically detecting a patient access disconnection.
