摘要：
The present invention relates generally to hemodialysis and similar dialysis systems that include various systems and methods that make hemodialysis more efficient, easier, and / or more affordable. One aspect of the present invention generally relates to a new fluid circuit for fluid flow. In one set of embodiments, the hemodialysis system may comprise a blood flow path and a dialysis fluid flow path, and the dialysis fluid flow path includes at least one balancing circuit, mixing circuit, and / or indicating circuit. In some cases, preparing the dialysis fluid by preparing the circuit can be separated from the patient dialysis. In some cases, the circuit may be formed, at least in part, in one or more cassettes, and is optionally interconnected with a conduit, a pump, and the like. In one embodiment, the fluid circuit and / or the various fluid passageways may be spatially and / or thermally isolated at least partially from the electrical components of the hemodialysis system. In some cases, the gas source may be in fluid communication with the dialysis fluid channel and / or the dialyzer, and when actuated, pressurize the dialysis fluid to pass through the dialyzer and pressurize the blood in the blood flow channel back to the patient. Such a system may be useful, for example, in any emergency situations (e.g., outages) where it is desired to return as much blood as possible to the patient. Further, in another aspect of the invention, the blood transfusing system may include one or more fluid handling devices, such as pumps, valves, mixers, etc., 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 using an external pump or other device that is removable in any event. In one embodiment, the at least one fluid handling device is generally rigid (e.g., having a spherical shape) and optionally includes a diaphragm within the device that divides the device into a first compartment and
