Extracorporeal blood filtering machine and methods
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.
Dialysis system including cassette with pumping tubes
A hemodialysis system includes a blood treatment machine, a blood pump housed by the blood treatment machine, a first dialysate pump housed by the blood treatment machine, a second dialysate pump housed by the blood treatment machine; and a fluid cassette including an upper portion and a lower portion. The fluid cassette further includes a blood pumping tube extending from the upper portion to the lower portion of the fluid cassette, a first dialysate pumping tube extending from the upper portion to the lower portion of the fluid cassette, and a second dialysate pumping tube extending from the upper portion to the lower portion of the fluid cassette.
Priming System and Method for Dialysis Systems
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.
Device for carrying out a method for conserving a blood treatment device, and method for conserving a blood treatment device
The present invention relates to extracorporeal blood treatment devices and methods and devices for conserving extracorporeal blood treatment devices. In accordance with the present invention, an antifreeze agent in introduced only into that part of the dialysis liquid system of the blood treatment device that includes the volume lying upstream of a sterile filter with which sterile substituate is recovered from the dialysis liquid. Accordingly, that part of the dialysis liquid system that includes the volume lying downstream of the sterile filter is not filled with an antifreeze agent. The present invention makes it possible, after removal of the sterile filter, to easily and safely separate a substituate segment from the rest of the dialysis liquid system and drain off liquid located in the substituate segment.
Systems and methods for priming hemodialysis using dialysis fluid
A method for priming a hemodialysis treatment includes: providing a disposable cassette including at least a portion of a dialysate circuit and at least a portion of a blood circuit; placing a dialyzer in fluid communication with the dialysate circuit via a to-dialyzer dialysate line and a from-dialyzer dialysate line; placing the dialyzer in fluid communication with the blood circuit via an arterial blood line and a venous blood line; placing a source of dialysis fluid in fluid communication with the dialyzer; priming the dialysate circuit with dialysis fluid from the source while both the to-dialyzer dialysate line and the from-dialyzer dialysate line are connected at their dialyzer ends to the dialyzer; and priming the blood circuit with dialysis fluid from the source by actuating at least one valve provided by the disposable cassette.
Renal failure therapy machines and methods including convective and diffusive clearance
A renal failure therapy machine includes a blood cleaning filter, a dialysis fluid circuit including a balance chamber, the balance chamber including a fresh dialysis fluid compartment configured to send fresh dialysis fluid to the blood cleaning filter and a used dialysis fluid compartment configured to receive used dialysis fluid from the blood cleaning filter, a fresh dialysis fluid line in fluid communication with the fresh dialysis fluid compartment of the balance chamber and the blood cleaning filter, and a flow restrictor in fluid communication with the blood cleaning filter, the flow restrictor configured to cause fresh dialysis fluid delivered from the fresh dialysis fluid compartment, through the fresh dialysis fluid line, to the blood cleaning filter to be pressurized so that a first amount of the fresh dialysis fluid performs convective clearance and a second amount of the fresh dialysis fluid performs diffusive clearance.
FLUID CIRCUIT FOR DELIVERY OF RENAL REPLACEMENT THERAPIES
A portable dialysis cabinet for use in dialysis. The portable dialysis cabinet can have a size and weight that facilitates easy movement of the cabinet from one location to another with relative ease. The portable dialysis cabinet can have additional features necessary to facilitate portability, such as wheels and a handle. In general, the portable dialysis cabinet can contain all the necessary components for performing a dialysis session.
Hemodialysis system including a disposable cassette
A dialysis system includes an on-line dialysate generator, a first dialysate pump in fluid communication with the on-line dialysate generator, and a second dialysate pump in fluid communication with the on-line dialysate generator. The dialysis system also includes a dialyzer in fluid communication with the first and second dialysate pumps. The dialysis system further includes a first valve located between the first dialysate pump and the dialyzer and a second valve located between the second dialysate pump and the dialyzer. The dialysis system is configured to alternate pumping of dialysate from the first and second dialysate pumps to the dialyzer using the first and second valves.
