Abstract: 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.

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.

Abstract: A dialysis system is disclosed that enables a patient to undergo both peritoneal dialysis and extracorporeal blood treatments. The system includes a base unit and a blood treatment unit configured to perform extracorporeal blood treatments on a patient. The blood treatment unit includes a user interface operable with a controller for displaying a calendar of days in which an extracorporeal blood treatment is scheduled to be performed. The base unit includes a base unit controller that is programmed to receive information indicative whether a peritoneal dialysis treatment or the extracorporeal blood treatment is to be performed. The base unit controller operates first software instructions when the base unit uses a first fluid stored in a fluid container when the peritoneal dialysis treatment is selected or operates second software instructions when the base unit uses a second, different fluid from an online source when the extracorporeal blood treatment is selected.

Abstract: A dialysis method to enable a patient to undergo both peritoneal dialysis and extracorporeal blood treatments is disclosed. The method includes determining, via a base unit controller, whether a peritoneal dialysis treatment or an extracorporeal blood treatment is to be performed. If the peritoneal dialysis treatment is to be performed, the method includes operating first software instructions that cause a base unit to use a first fluid stored in a fluid container. If the extracorporeal blood treatment is to be performed, the method includes operating second software instructions that cause the base unit to use a second, different fluid from an online source and selectively move the second, different fluid to a blood treatment unit for use in the extracorporeal blood treatment. The blood treatment unit is operable with the base unit to perform the extracorporeal blood treatment on a patient.

Abstract: The application is directed to an extracorporeal blood processing system capable of using dialysate to prime the system. A plastic molded compact manifold supports molded blood and dialysate fluidic pathways along with relevant sensors, valves and pumps. The compact manifold is also disposable in one embodiment and can be detachably installed in the dialysis machine. A two-way valve in the manifold is used to direct the dialysate flow through the blood circuit to prime the circuit for use in treatment.

Abstract: It is disclosed an apparatus for extracorporeal blood treatment (1) having a control unit (15) connected to an ultrafiltration device (20) and to a fluid preparation section (30) of fresh dialysis liquid. The control unit (15) is configured to receive measured values of the change of blood volume, the amount of ultrafiltration volume, and conductivity or to the concentration for at least one substance in the blood (BV %mes(t); UFmes(t), WLmes(t); Cbmes(t)); the control unit (15) is also configured to receive prescription values for the same parameters and to control ultrafiltration and adjust conductivity in the fresh dialysis liquid based on the difference between said measured values and said prescription values.
