摘要： A hemodialysis system is disclosed. The hemodialysis system includes a dialyzer, a saline container including saline, and a disposable set comprising a blood pumping tube fluidly connected to a first end of the dialyzer, an arterial line fluidly connected to a first end of the blood pumping tube, a venous line fluidly connected to a second end of the dialyzer, a saline line fluidly connected to the blood pumping tube and the saline container, and a dialyzer line fluidly connected to a second end of the blood pumping tube and a second end of the dialyzer. The hemodialysis system also includes a dialysis instrument comprising an arterial line clamp, a venous line clamp, and a saline valve. The saline rinses blood out of the arterial line when the venous line clamp is closed, the arterial line clamp is opened, and the saline value is opened.

摘要： An example peritoneal dialysis system is disclosed. The example peritoneal dialysis system includes an automated peritoneal dialysis (“APD”) machine configured to remove ultrafiltrate (“UF”) from a patient and record how much UF has been removed. The APD machine operates according to a prescription to remove the UF. The system also includes a server in communication with the APD machine. The server analyzes the UF data to determine if the prescription is to be modified to compensate for changes to the patient's renal function or renal transport characteristics.

摘要： A hemodialysis system is disclosed. The hemodialysis system includes a disposable set including a blood pumping tube, a fresh dialysate pumping tube, and a spent dialysate pumping tube. The hemodialysis system also includes a dialysis instrument including a blood pump head, a fresh dialysate pump head, a spent dialysate pump head, a first motor positioned and arranged to operate the blood pump head, a second motor positioned and arranged to operate the fresh dialysate pump head, and a third motor positioned and arranged to operate the spent dialysate pump head. When the disposable set is loaded into the dialysis instrument, the blood pumping tube comes into registry with the blood pump head, the fresh dialysate pumping tube comes into registry with the fresh dialysate pump head, and spent dialysate pumping tube comes into registry with the spent dialysate pump head.

摘要： An apparatus for extracorporeal treatment of fluid and a process of setting up a medical apparatus for the delivery or collection of fluids are disclosed. According to the apparatus and the process, a control unit (10) is configured calculate set values of two or more of the fluid flow rates by imposing that an emptying time of containers of fresh fluid (16, 20, 21, 26) and/or a filling time of a waste container is substantially same as, or multiple of, the emptying time of one or more of the other containers of fresh fluid.

摘要： A method for priming a renal therapy machine is disclosed. The method includes communicating a source of a physiologically compatible solution with a blood circuit and moving the physiologically compatible solution from the source to the blood circuit. The method also includes moving the physiologically compatible solution through the blood circuit to prime the blood circuit. The method further includes moving the physiologically compatible solution from the blood circuit though porous fibers of a blood filter, causing air to be purged from the blood circuit and into a dialysis fluid circuit portion of the blood filter.

摘要： An example peritoneal dialysis system is disclosed. The example peritoneal dialysis system includes an automated peritoneal dialysis (“APD”) machine comprising a pumping mechanism and a peritoneal dialysis fluid heater. The example peritoneal dialysis system also includes a disposable set comprising a disposable cassette operable with the pumping mechanism and a heater bag operable with the heater. The example peritoneal dialysis system additionally includes a conductivity sensor positioned and arranged to provide feedback to the APD machine. The example APD machine is configured to mix a peritoneal dialysis fluid for treatment in the heater bag using a plurality of peritoneal dialysis constituent fluids. In addition, the example APD machine is configured to use feedback from the conductivity sensor to evaluate the mixed peritoneal dialysis fluid for treatment.

摘要： The specification discloses a portable dialysis machine having a detachable controller unit and base unit. The controller unit includes a door having an interior face, a housing with a panel, where the housing and panel define a recessed region configured to receive the interior face of the door, and a manifold receiver fixedly attached to the panel. The base unit has a planar surface for receiving a container of fluid, a scale integrated with the planar surface, a heater in thermal communication with the planar surface, and a sodium sensor in electromagnetic communication with the planar surface. Embodiments of the disclosed portable dialysis system have improved structural and functional features, including improved modularity, ease of use, and safety features.
