Abstract

The invention belongs to the technical field of hemodialysis membranes, and discloses a nano magnetic hemodialysis membrane and a preparation method thereof. A preparation system of the nano magnetichemodialysis membrane comprises a time control module, a temperature control module, a main control module, a material selection module, a fusion module, a modification module, and a mixing module. The nano magnetic hemodialysis membrane provided by the invention has the characteristics of high strength, high wear resistance, good tear resistance and good fatigue resistance. At the same time, a reaction process of the nano magnetic hemodialysis membrane is simple, convenient and feasible; the thin-layer nano composite hemodialysis membrane provided by the invention has the characteristics of permanent hydrophilicity, low protein adsorbability and excellent biocompatibility; and the thin-layer nano composite hemodialysis membrane provided by the invention has high permeability, high separation performance and anti-pollution and anti-coagulation properties.

Description

technical field [0001] The invention belongs to the technical field of hemodialysis membranes, in particular to a nanometer magnetic hemodialysis membrane and a preparation method thereof. Background technique [0002] The purpose of hemodialysis is to replace some of the functions lost in renal failure, such as removing metabolic waste and regulating water, electrolyte and acid-base balance. Its basic principles are dispersion, osmosis, convection and ultrafiltration. The exchange of solute and water during dialysis constitutes the theoretical basis for removing toxins, removing water, and supplementing necessary substances during hemodialysis. Small molecular substances in the blood of uremia patients, such as creatinine, urea nitrogen, and potassium, diffuse into the dialysate, and the concentration of ionic sodium and chloride in the dialysate is the same as that in the blood. Bases, calcium ions, etc. diffuse into the blood, thereby achieving the purpose of removing t...
