摘要：
The present invention generally relates to hemodialysis and similar dialysis systems that include a variety of systems and methods that make hemodialysis more efficient, easier, and / or more affordable. One aspect of the present invention relates generally to new fluid circuits for fluid flow. In one set of embodiments, the hemodialysis system can include a blood flow passage and a dialysate flow path, wherein the dialysate flow path includes one or more balance circuits, mixing circuits, and / or indicator circuits. In some cases, preparing the dialysate by preparing the circuit can be separated from patient dialysis. In some cases, the circuit may be at least partially formed in one or more cassettes, optionally interconnected with conduits, pumps, and the like. In one embodiment, the fluid circuit and / or the various fluid flow paths may be at least partially isolated spatially and / or thermally from electrical components of the hemodialysis system. In some cases, the gas source may be in fluid communication with the dialysate flow path and / or the dialyzer, and when operated, may pressurize the dialysate to pass through the dialyzer and force the blood in the blood flow passages back to the patient. Such a system may be useful, for example, in any emergency situation (eg, a power outage) that requires returning as much blood as possible to a patient. Further, in another aspect of the present invention, the hematopoietic system may include one or more fluid handling devices such as pumps, valves, mixers, and the like, which may be operated using a control fluid such as air. In some cases, the control fluid may be delivered to the fluid handling device in any case using a removable external pump or other device. In one embodiment, the one or more fluid handling devices are generally rigid (eg, have a spherical shape) and, optionally, include a diaphragm inside the device that divides the device into a first compartment and a second compartment.본 발명은 일반적으로 혈액투석
