AI Technical Summary

Problems solved by technology

The shell of the hemodialyzer is often made of polycarbonate. When the dialyzer is sterilized, the polycarbonate may decompose and release bisphenol A, which poses a certain safety hazard.
[0004] To sum up, at present, the materials of the hemodialysis membrane and shell of the hemodialyzer are mainly petroleum-based polymers, which have problems such as poor hydrophilicity, easy blood coagulation, and inability to degrade. Research and development of environmentally friendly bio-based polymers Hemodialysis membrane and housing are important directions for the development of hemodialyzers in the future

Abstract

The invention discloses an environment-friendly bio-based polymer hemodialyzer casing material. The casing material is a blend which comprises the following raw materials in percentage by mass: 90-99% of environment-friendly bio-based polymer, 0.4-8% of plasticizer, 0.2-6% of lubricant, 0.1-2% of antioxidant, 0.2-3% of heat stabilizer and 0.1-4% of inorganic filler. The raw material environment-friendly bio-based polymer has the advantages of wide sources and the like, and is renewable and degradable. The prepared environment-friendly bio-based polymer hemodialyzer casing has higher biocompatibility, and can obviously lower the side effect of hemodialysis; and the waste hemodialyzer casing can be degraded by proper treatment, thereby greatly reducing the environmental pollution.

Description

technical field [0001] The invention relates to the field of environment-friendly bio-based polymer membrane material and hemodialysis, in particular to an environment-friendly bio-based polymer material hemodialyzer housing material. Background technique [0002] Due to the aggravation of human aging, the increase of patients with diabetes and hypertension, the number of patients with renal failure (renal failure) is on the rise. Hemodialysis is one of the most important and effective methods for the treatment of renal failure. According to statistics, among every million people in China, 90 to 100 people will suffer from chronic renal failure every year, and the population of China has exceeded 1.32 billion in 2007, which means that about 130,000 new cases of chronic renal failure will be added every year. patient. The maturity and optimization of dialysis technology and the improvement of the economic level in developing countries make more and more people have the oppor...
