Polyester anticoagulation blood dialysis membrane and preparation method thereof

Abstract

The invention discloses a polyester anticoagulation blood dialysis membrane. The dialysis membrane takes a polyester material as a main body. The polyester anticoagulation blood dialysis membrane is prepared from 10 to 24 parts of polyester material, 5 to 9 parts of polysulfone, 4 to 9 parts of polymethyl methacrylate, 6 to 9 parts of protein fiber, 15 to 20 parts of protein mixed material, 5 to 9parts of peptidoglycan, 3 to 8 parts of glycerol and 8 to 15 parts of anticoagulant. The invention further discloses a preparation method of the polyester anticoagulation blood dialysis membrane. Thepreparation method comprises the following steps: S1, mixing silk making materials; S2, removing air bubbles; S3, mixing the anticoagulant; S4, spinning. The polyester anticoagulation blood dialysismembrane has the advantages of good anticoagulation effect, higher flexibility and high retention rate of micromolecular proteins.

Description

technical field

[0001] The invention relates to the field of medical equipment, in particular to a polyester anticoagulant hemodialysis membrane and a preparation method thereof. Background technique

[0002] Hemodialysis (HD) is one of the renal replacement therapies for patients with acute and chronic renal failure. It drains the blood from the body to the outside of the body through a dialyzer composed of countless hollow fibers, and the blood and the electrolyte solution (dialysate) with a similar concentration to the body are exchanged through diffusion / convection inside and outside the hollow fibers , remove metabolic waste from the body, maintain electrolyte and acid-base balance; remove excess water from the body at the same time, and return the purified blood to the entire process called hemodialysis.

[0003] Dialysis membrane is a separation membrane driven by concentration difference. According to the particle size of the separated solute, the dialysis membrane...
