Background
Artificial liver is a temporary or partial replacement of liver function by means of an extracorporeal mechanical, chemical or biological device to assist in the treatment of liver insufficiency or related diseases. The artificial liver is mainly different from the common medical drug treatment in that the artificial liver mainly treats diseases through 'functional replacement' and the artificial liver mainly treats diseases through 'functional enhancement'. The artificial liver technology mainly comprises blood perfusion, plasma replacement and continuous blood purification technology. The exact meaning of hemoperfusion is blood adsorption, i.e. substances dissolved in blood are adsorbed onto solid substances with a large surface area to remove toxic substances from blood, and hemoperfusion equipment mainly consists of a hemoperfusion machine, accessories (arterial and venous pipelines, etc.) and a hemoperfusion apparatus. Plasma replacement is a commonly used artificial liver technique, and the classical method is to extract the blood of a patient, separate the plasma and cellular components, discard the plasma, and return the cellular components, supplemented albumin, plasma, and balanced fluid to the body for the purpose of removing pathogenic mediators. The continuous blood purification technology is a new technology for clinically treating severe patients, especially patients with hemodynamics instability and severe high catabolism, along with the continuous and deep research on the pathophysiology and pathogenesis of acute renal failure and the gradual innovation of the blood purification technology.
