A method for operating a dialysis machine to conduct a dialysis treatment on a patient (e.g., a peritoneal dialysis machine) may include transferring dialysate from a first bag, and automatically determining the dialysate from the first bag has completely transferred. After determining the dialysate has completely transferred from the first bag, switching from the first bag to a second bag of dialysate. The method may further include transferring dialysate from the second bag in response to the detection of the completed transfer of the first bag, and automatically determining the dialysate from the second bag has completely transferred. The method may further include determining if the respective first or second bag has completely transferred by comparing a dialysate bag volume transferred to the patient to a detected volume of the respective first or second bag. Systems with dialysis machines for performing such a method are disclosed as well.

A system is provided for operation with a facility providing peritoneal dialysis exchanges for multiple peritoneal dialysis patients. The system can include a peritoneal dialysis solution supply, peritoneal dialysis sets to deliver peritoneal dialysis solution to the peritoneal dialysis patients at the facility, a computer, and a treatment station. The computer can electronically read a prescription for a patient, electronically identify a quantity of the peritoneal dialysis solution from the prescription, and electronically identify a peritoneal dialysis set from the peritoneal dialysis sets for use with the identified quantity of the peritoneal dialysis solution. The treatment station can allow an identified peritoneal dialysis set to be fluidly connected to the peritoneal dialysis solution supply so that the identified quantity of the peritoneal dialysis solution may be metered from the dialysis solution supply to the patient to perform a peritoneal dialysis treatment at the facility and according to the prescription.

Systems and methods suitable for extracorporeal lung support are provided that expose blood, across a semipermeable membrane, to a dialysis liquid. The dialysis liquid features a buffering agent and has a high buffering capacity for H.sup.+ ions. Carbon dioxide, bicarbonate and hydrogen cations are transported across a semipermeable membrane into the dialysis liquid. The dialysis fluid may be recycled and repeatedly used, and its pH may be adjusted, and other fluids added to it. Certain substances may be removed from the blood, and the amount of these substances removed from the blood may be substantially automatically or substantially continuously monitored or quantified. The systems and methods are suitable for treating or preventing respiratory acidosis, metabolic acidosis, and diseases featuring lung malfunction, kidney malfunction, or liver malfunction.

A medical fluid delivery system includes a source of purified water; a source of concentrate for mixing with water from the water source; a disposable set including a pumping portion, a water line in fluid communication with the source of purified water and the pumping portion, the water line including a filter for filtering the water, a concentrate line in fluid communication with the concentrate source and the pumping portion, and a heater/mixing container in fluid communication with the pumping portion; a medical fluid delivery machine including, a pump actuator operable with the pumping portion of the disposable set, and a heater/mixing pan configured to support the heater/mixing container; and at least one leveling foot positioned and arranged to enable the heater/mixing pan to be oriented in a desired position for mixing the concentrate and purified water. A leveling tray and leveling foot are provided additionally.

The current invention relates to a peritoneal dialysis filter device, which comprises a housing comprising a first port and a second port, and a hollow fibre membrane formed from hollow hydrophilic fibres within the housing. When in use, a dialysate from a subject enters the filter device through the first port and exits via the second port in an outflow direction, and a regenerated dialysate from a sorbent system enters the filter device through the second port and exits via the first port in an inflow direction. Also disclosed herein is a peritoneal dialysis system comprising said filter device, a method for controlling dialysate flow in a peritoneal dialysis system, and a haemodialysis device.

The present invention relates to a container arrangement having a first container wherein the first container is either a container in which a concentrate is located that is configured to form a ready-to-use dialysis solution or a component thereof on a dilution with a solvent, preferably with pure water (water for injection), or an empty container, wherein the container arrangement has a second container in which the first container is received, with the first container having a greater elasticity than the second container and with the first container being configured to expand up to the second container.

A medical fluid container preparation system includes: a conveyor for conveying the medical fluid container, a water injector located along the conveyor, a mechanism for carrying the water injector towards and away from the medical fluid container; a sensor positioned and arranged to determine a location of the medical fluid container moving along the conveyor, and a control unit configured to read an output from the sensor and to cause (i) the mechanism to move the water injector towards the medical fluid container an amount based upon the location of the medical fluid container obtained from the sensor output and (ii) the water injector to inject a volume of water between the medical fluid container and an overpouch into which the medical fluid container is placed.

Automated control mechanisms and methods for controlling fluid flow in a hemodialysis apparatus are described. The methods can involve a controller receiving information from a pressure sensor in a control chamber of a reciprocating diaphragm-based blood pump and causing the application of a time-varying pressure waveform on a diaphragm of the blood pump during a fill-stroke of the blood pump. The controller can be configured and programmed to monitor a pressure variation in the control chamber measured by the pressure sensor and to compare the measured pressure variation to a pre-determined value. Based on such comparison, the controller can initiate a procedure to pause or stop a dialysate pump of the hemodialysis apparatus if the magnitude of the measured pressure variation deviates from the pre-determined value.

The present invention relates to a magazine having a plurality of solution bags for dialysis received therein, wherein the plurality of solution bags are identical; wherein the plurality of solution bags are fixed in a stationary manner in an identical orientation at different, but identically designed holding positions of the magazine; and wherein the holding positions are configured such that the solution bags can be removed from the magazine. The invention furthermore relates to a method of filling the solution bags.

A peritoneal dialysis (“PD”) system includes a plurality of PD fluid components, a reusable PD fluid line selectively fluidly communicating with the PD fluid components, a source of PD fluid selectively fluidly communicating with the reusable PD fluid line, a source of anti-scaling fluid selectively fluidly communicating with the reusable PD fluid line, and a control unit configured to (i) operate the plurality of PD fluid components during treatment using PD fluid from the source heated to a treatment temperature, and (ii) circulate unused PD fluid heated to a disinfection temperature in combination with anti-scaling fluid from the source of anti-scaling fluid after treatment for disinfecting the plurality of PD fluid components and the reusable PD fluid line, the anti-scaling fluid provided in an amount configured to lower the pH of the unused PD fluid to a level below which precipitates are formed and above which the pH causes disinfection.
