The biggest difference between hemopurification and hemodialysis is that hemopurification is a total treatment method, and hemopurification includes hemodialysis. The so-called blood purification is the use of various means to expel toxic components from human blood, so as to achieve the purpose of treating diseases. For example, patients with acute poisonous mushroom poisoning, which is common in clinical practice, can be treated by blood purification to expel toxins from the blood. In addition, organophosphorus pesticide poisoning, etc., can also be treated by blood purification methods. And hemodialysis refers to the artificial kidney treatment method, using special instruments to replace the function of kidney, through hemodialysis, the excessive toxic urea nitrogen, creatinine and other toxic substances in the blood, through the machine to excrete out of the body, instead of the function of human kidney. Many chronic uremic patients in China are relying on hemodialysis, while achieving long-term survival.
