Description

Technical Field

[0001] The utility model relates to the technical field of hemodialysis equipment, in particular to a hemodialysis device for nephrology. Background Art

[0002] Hemodialysis is one of the renal replacement therapies for patients with acute and chronic renal failure. It drains blood from the body to the outside of the body and passes through a dialyzer composed of countless hollow fibers. The blood and the electrolyte solution (dialysate) containing electrolytes at similar concentrations to the body are exchanged inside and outside the hollow fibers through diffusion, ultrafiltration, adsorption and convection principles to remove metabolic waste from the body, maintain electrolyte and acid-base balance, remove excess water from the body, and return the purified blood. The whole process is called hemodialysis.
