The present invention relates to the technical field of medical devices, and specifically discloses a blood purifier free of dialysate. The blood purifier comprises a blood filter, a blood purification unit, a venous pot, a blood pump, a first flow control booster pump, a second flow control booster pump and a waste liquid bag. According to the invention, blood in human blood vessels is introducedto the blood filter to isolate primary filtrate containing water, electrolytes, trace elements and various medium and small molecular metabolic wastes. The primary filtrate is injected into the bloodpurification unit through the flow control booster pump and then separated into secondary filtrate containing water and electrolyte ions and waste liquid containing various medium and small molecularmetabolic wastes. The secondary filtrate and the blood flowing through the blood filter are merged through the venous pot and then re-injected into the human venous blood vessels, and the waste liquid is discharged into a waste liquid bag. The blood purifier does not require the use of dialysate and replacement fluid. The blood purifier is safe, reliable, exact in curative effect, and little in side effects. The blood purifier is basis for future integration and portability, has unlimited broad prospects and is an important milestone in blood purification.
Description
technical field [0001] The invention belongs to the technical field of medical equipment, in particular to a blood purifier without dialysate. Background technique [0002] Uremia is a clinical syndrome that occurs in the end stage of renal failure. Hemodialysis is a commonly used method for treating uremia, which can effectively maintain the life of uremia patients. The principle is to use the two-way separation effect of the semipermeable membrane to introduce the patient's blood and dialysate into the dialyzer (artificial kidney) at the same time. The two sides of the membrane flow in opposite directions. With the help of the solute gradient, osmotic gradient and water pressure gradient on both sides of the membrane, through dispersion and convection, high-concentration metabolites and toxins are removed, the required substances are replenished, and electrolyte and acid-base balance disorders are corrected. However, a large amount of dialysate is needed in the hemodialys...
