    摘要: The extracorporeal blood treatment apparatus described herein include components configured to detect liquid leaking from one or more liquid circuits in the extracorporeal blood treatment apparatus and methods of detecting liquid leaks in extracorporeal blood treatment apparatus. The components used to detect leaks include one or more remote pressure ports connected to one or more local pressure ports on one or more pressure sensors by one or more fluid-filled pressure lines. The fluid in the pressure lines transmits pressure exerted on a remote pressure port by any collected liquid to the local pressure port of the pressure sensor.

    摘要: A dual-stage filtration system and methods for using the same include first and second filtration cartridges (122, 138) particularly suited for hemodiafiltration and/or hemodialysis. As fluid enters the first filtration cartridge (122), the hydrogen ion concentration (pH) is reduced by exposing it to an acidic solution such as citric acid across a filter membrane (124). This stage allows for improved removal of certain toxins in the fluid, such as protein-bound substances that disassociate more readily from proteins at a lower pH. As the filtered fluid enters the second filtration cartridge (138), the pH of the fluid is restored to normal levels prior to infusion to a patient.

    摘要: Systems and methods utilize semipermeable nanotubes in conjunction with application of controlled electrical potentials across semipermeable nanotube walls allow selective transport of charged impurities (e.g., charged impurities, ions, etc.) from a fluid into these nanotubes. Impurities collected in these nanotubes can then be removed from the fluid, (e.g., blood) as a waste stream. A collection of semipermeable nanotubes each carrying a waste stream can be aggregated and merged into a ureter for excretion thereby providing an artificial kidney system. Sensors that detect/measure various impurities may be included in the system to feed information to a microprocessor to inform on concentrations of impurities, and thereby control electrical potentials applied to the system.

    摘要: A dialyzer composed of: first and second dialyzation chambers, and an intermediate chamber interposed between the first and second dialyzation chambers. Each dialyzation chamber has opposed first and second ends and contains a filter member that separates the chamber into a blood compartment and a dialysate compartment. Each of the compartments extends between first and second ends. Each of the chambers has a respective one of a blood inlet or outlet and a dialysate inlet or outlet arranged so that blood and dialysate flow in counter-current to one another in both chambers. The intermediate chamber is connected to form a dialysate-free blood flow passage between the blood compartments.
