An apparatus for extracorporeal blood treatment for chronic therapy comprises a nutritional bag (33) containing a nutritional solution, a weighing device (36) configured to determine a weight (W) of the nutritional bag (33), a nutritional line (34) for infusing the nutritional solution into either a blood return line (7) or into the patient vascular system. An ultrafiltration device (30) is configured to achieve a fluid removal from the patient through a semi- permeable membrane (5) of a filtration unit (2) and a sensor (31, 32) is configured to determine an ultrafiltration rate (UFR). A control unit (100) connected to the ultrafiltration device (30), to the weighing device (33) and to the sensor (31, 32) is programmed for receiving a patient prescription and for controlling the ultrafiltration device (30) to achieve the patient prescription based on the weight (W) and on ultrafiltration rate (UFR).

A dialysis system may include a blood circuit, a cassette, a subsystem having a processor, a sensor, and a blood pumping mechanism, a housing in which the subsystem is arranged, a movable support arranged in the housing and configured to hold the sensor and/or the blood pumping mechanism of the subsystem, a cassette holder configured to removably receive the cassette, and a loading system. The loading system may be configured to move the movable support, e.g. by an axial movement, to a first position and to a second position relatively to the housing while the cassette holder is fixedly arranged in the housing. The loading system may have an electric motor controlled by the processor, a drive assembly coupled to the electric motor, and a guiding assembly configured to cooperate with the drive assembly.

There is provided an apparatus for extracorporeal blood treatment, comprising: a treatment unit (10), a blood circuit coupled to the treatment unit (10), a blood pump (22) configured to be coupled to a pump section of the blood circuit, at least two fluid lines (40, 60, 70, 70b, 70c) connected to respective containers (48, 68, 78, 88) and to the blood circuit and/or to the treatment unit (10). The apparatus further comprises a fluid dispatcher (300) having a common zone (310), wherein said at least two fluid lines (40, 60, 70, 70b, 70c) are connected one to the other at said common zone (310) upstream the blood circuit, for selectively allowing fluid flow between said at least two fluid lines (40, 60, 70, 70b, 70c) through said common zone (310).

The present invention generally relates to hemodialysis and similar dialysis systems, including a variety of systems and methods that would make hemodialysis more efficient, easier, and/or more affordable. One aspect of the invention is generally directed to new fluid circuits for fluid flow. In one set of embodiments, a hemodialysis system may include a blood flow path and a dialysate flow path, where the dialysate flow path includes one or more of a balancing circuit, a mixing circuit, and/or a directing circuit. Preparation of dialysate by the preparation circuit, in some instances, may be decoupled from patient dialysis. In some cases, the circuits are defined, at least partially, within one or more cassettes, optionally interconnected with conduits, pumps, or 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, a gas supply may be provided in fluid communication with the dialysate flow path and/or the dialyzer that, when activated, is able to urge dialysate to pass through the dialyzer and urge blood in the blood flow path back to the patient. Such a system may be useful, for example, in certain emergency situations (e.g., a power failure) where it is desirable to return as much blood to the patient as possible. The hemodialysis system may also include, in another aspect of the invention, one or more fluid handling devices, such as pumps, valves, mixers, or the like, which can be actuated using a control fluid, such as air. In some cases, the control fluid may be delivered to the fluid handling devices using an external pump or other device, which may be detachable in certain instances. In one embodiment, one or more of the fluid handling devices may be generally rigid (e.g., having a spheroid shape), optionally with a diaphragm contained within the device, dividing it into first and second compartments.

A dialysis system is provided that includes a dialysis machine and a potassium sensing device that is configured to measure the concentration of potassium in the patient's blood, in spent dialysate resulting from treating the patient, or in both. The potassium sensing device can be configured to generate a sensed value of the concentration of potassium. A control and computing unit, including a processor and a memory, is configured to receive the sensed value, compare the value with one or more values stored in the memory, and generate a control signal based on the comparison. A potassium infusion circuit uses the control signal to infuse supplemental potassium solution into the treatment dialysate, a replacement fluid, or both. The memory can include stored patient-historical and population data.

A method includes, after an extracorporeal blood treatment, connecting a fluid source to an access line that is connected to a patient, and delivering a fluid from the fluid source to the access line to infuse blood from the access line to the patient, wherein the fluid delivered to the access line has a temperature from about 30 degrees Celsius to about 38 degrees Celsius.
