摘要： An automated peritoneal dialysis apparatus includes at least one pump and a memory device configured to simultaneously store a first standard ultrafiltration (“UF”) therapy prescription with a longer duration and a lower dextrose concentration and a second standard UF therapy prescription with a shorter duration and a higher dextrose concentration. A logic implementer of the automated peritoneal dialysis apparatus is programmed to receive a patient weight value and determine a weight difference between the patient weight value and at least one prior patient weight value. When the weight difference is below a threshold, the logic implementer causes the first standard UF therapy prescription and the second standard UF therapy prescription to be displayed as possible options for selection and when the weight difference is above the threshold, the logic implementer prevents the second standard UF therapy prescription from being displayed as a possible option for selection.

摘要： A peritoneal dialysis system includes first and second concentrate sources in selective fluid communication with a medical fluid pumping cassette, the first and second concentrate sources holding first and second peritoneal dialysis concentrates, respectively; a pump actuator configured to cause the medical fluid pumping cassette to pump the first and second concentrates; and a processor and memory configured to (i) determine a cumulative volume of at least one of the first or second peritoneal dialysis concentrates pumped from the medical fluid pumping cassette by the pump actuator, (ii) compare the cumulative volume to a threshold, and (iii) if the cumulative volume is outside of the threshold, modify a subsequent stroke volume of at least one of the first or second pump chambers actuated by the pump actuator in an attempt to cause an updated cumulative volume for the at least one peritoneal dialysis concentrate to be within the threshold.

摘要： 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.

摘要： 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.

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 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.
