FLUID REGENERATION SYSTEM AND METHOD Russian patent published in 2011 - IPC A61M1/16 A61M1/34 

FIELD: medicine.

SUBSTANCE: what is offered is a dialysis fluid regeneration system for blood purification system which comprises a number of devices. A device for dialysis fluid feed from a dialysis fluid and blood cell in a filtration manifold. The filtration manifold filters water from the dialysis fluid for producing the concentrated dialysis fluid. A device for discharge of a part of the concentrated dialysis fluid from the system. A device for one-line return of a non-discharged part of the concentrated dialysis fluid and water filtered from the dialysis fluid as a regenerated dialysis fluid into the dialysis fluid cell and/or into blood immediately. What is also offered is a method of dialysis fluid regeneration for the blood purification system after the dialysis fluid reacts with blood. Blood is supplied into the filtration device; the prepared filtrate representing water is returned into the dialysis fluid and blood cell, and the concentrated dialysis fluid liquid is supplied into the filtration device for discharge a part of the concentrated dialysis fluid from the system as the discharge fluid. The remained concentrated dialysis fluid is mixed with the filtrate prepared in the filtration device, and as the regenerated dialysis fluid is returned into the dialysis fluid and blood cell and/or into blood immediately.

EFFECT: invention enables continuous blood purification combined with the use of the small amount of the dialysis fluid in the loop with no fresh dialysis fluid added ensured by the developed regeneration system of the discharged fluid.
