A customizable modular dialysate regeneration assembly with connectable sorbent packaging systems. The dialysate regeneration assembly can be customized based on patient parameters or dialysis session parameters. A processor can be included that can determine the correct amount of each sorbent material necessary for a given patient and a given dialysis session.

Systems and methods of generating and regenerating peritoneal dialysate are provided. The systems and methods use a dialysate regeneration module, a sterilization module and concentrates to prepare peritoneal dialysate from used peritoneal dialysate or source water. An optional integrated cycler for direct infusion of the generated peritoneal dialysate is included. Optional dialysate storage containers are provided for storage of the peritoneal dialysate prior to use.

The present invention relates to a dialysate regeneration device capable of continuously regenerating dialyzate in a dialysis treatment process, or regenerating the dialysate after dialysis, which can greatly reduce the amount of dialysate and clean water used in the dialysate process, The dialysate regeneration device is particularly suitable for dialysate in an emergent condition. The dialysate regeneration device comprises a pump, a reverse osmosis component, an electric catalysis reactor based on BDD electrode and a dialysate water tank. An upstream of the reverse osmosis component is communicated with a liquid outlet of a dialysis machine via the pump; the downstream of the reverse osmosis component comprises two branches, one branch (concentrated water) converges the other branch (clean water) through two groups of electric catalysis reactors and is communicated with a liquid inlet of the dialysate water tank via the confluence port ; a liquid outlet of the dialysate water tank is communicated with the liquid inlet of the dialyzate machine; a filter and air emission component are arranged on a communication channel between the outlet of the electric catalysis reactors and the confluence port.

A dialysis apparatus for treating a patient with liver and/or kidney disease. In one embodiment a liver dialysis apparatus comprises an artificial liver. The artificial liver comprises a blood compartment, a vegetable protein compartment, and a clear dialysis compartment. In another embodiment the liver dialysis apparatus comprises cartridge made up of at least one layer of vegetable protein. In a further embodiment of the invention a dialysate regeneration device is provided which comprises at least one layer of vegetable protein. The vegetable protein is preferably a soy protein. The soy protein may be unmodified soy protein with urease enzyme activity, modified soy protein with or without urease activity, alone or in combination.

Systems and methods are provided for performing selective sorbent-based regeneration of dialysate. The systems and method provide for dialysate regeneration to be carried out intermittently throughout a dialysis session, decreasing the necessary amounts of sorbent materials and infusates to conduct dialysis. The system and methods allow for regeneration of dialysate as needed based on the concentration of waste species in the dialysate, allowing for effective treatment with a decreased need for sorbent materials.

The invention discloses a preparation method of active carbon with a high specific surface area made from bamboo wood, and belongs to the technical field of resource comprehensive utilization. The method comprises the steps that the abandoned bamboo wood is cleaned, aired, carbonized, then subjected to furnace cooling, broken into certain granularity, dried, and packaged for use; KOH and a carbonized material are mixed uniformly, put in a ceramic crucible and placed in a microwave device; nitrogen is introduced to a furnace to exhaust air in the furnace; heating with microwaves is performed; in the last few minutes of the heating, CO2 is blown in quickly through a conduit communicated with the bottom of the ceramic crucible, and an ultrasonic generator is started simultaneously; after the heating, water washing with tap water is performed and residual KOH is recovered; washing is performed repeatedly with an appropriate amount of hydrochloric acid; cleansing with the tap water and drying are performed; and the active carbon with the high specific surface area made from the bamboo wood is obtained. The active carbon produced by the method is high in specific surface area, high in adsorption capacity, and lower in ash content, has well-developed pores, and can be applied in the medical fields of blood purification, dialysate regeneration and the like after appropriate disinfection and refining.

The invention relates to the field of blood purifying equipment, and discloses a dialyzate regenerating device and a blood purifying system. The dialyzate regenerating device comprises a first flow pump, a purifying unit, a liquid storage pot, a second flow pump and an outer cavity of a dialyzer which communicate with each other through pipelines to form a circulating loop, wherein an ion concentration adjusting unit and an acid-base balance adjusting unit are further arranged on the pipeline between the purifying unit and the liquid storage pot; an electrolyte adjusting unit is further connected on the pipeline between the output end of the liquid storage pot and the inlet of the outer cavity of the dialyzer; and a sensor group used for detecting the ionic concentration, the pH value and the amount of liquid in the liquid storage pot is arranged in the liquid storage pot. For the dialyzate regenerating device and the blood purifying system provided by the invention, the recycling of the dialyzate can be realized, the use amount of dialyzate in the dialysis process is greatly reduced, the dialysis cost is reduced, the integral size of the dialysis device is reduced, the carrying is convenient, and due to the modular design, the system can realize various functions.

The invention provides a method and an apparatus or system for dialysis. The method and apparatus or system are useful for removing an undesirable protein-binding substance such as a toxin from a biological fluid such as blood or blood plasma. As such, the method and apparatus or system are useful for treating a subject in need of dialysis such as a subject suffering from hepatic disease. The methods feature a) dialyzing a biological fluid against a dialysis fluid containing an adsorber for a protein-binding substance to be removed through a semipermeable membrane, b) adjusting the dialysis fluid so that the binding affinity of the adsorber for the protein-bound substance to be removed is lowered and the substance to be removed passes into solution, and c) balancing the volume or flow of one or more fluids in the apparatus or system suitable for dialyzing a biological fluid containing a protein-binding substance to be removed. The apparatus or system features a) a biological fluid circuit (3); b) a dialysis fluid circuit (2); c) a means (4; 6; 7; 8; 9) for solubilizing the protein-binding substance to be removed; d) a dialysis, filtration or diafiltration device (5); e) a balancing system or apparatus suitable for balancing the volume or flow of one or more fluids in the apparatus or system suitable for dialyzing a biological fluid containing a protein-binding substance to be removed; and f) a dialysate regeneration unit.
