On July 20, 2022, China's leading hemodialyzer manufacturer: SDWG Blood Purification Technology Corporation announced that the company has successfully realized the "mass production of hollow fiber membranes" technology for new medical materials.
Walking into SDWG's dialyzer workshop, the fully automatic production line is running at high speed, and dialyzers are sent to the international market from here.
For patients who need dialysis, the dialyzer is equivalent to an "artificial kidney". The hollow fiber membrane is the most core component in the dialyzer, and almost all functions are realized by it, and it is also the most technically difficult part.
Eight years ago, there were only three companies in the world that mastered this technology.
Technological innovation is the strategic direction of enterprise development. After years of technological innovation and accumulation, the company has more than 40 kinds of products to break the foreign monopoly, and obtains one invention patent every year on average, and there are 18 patents so far.
There are more than 50 varieties of hemodialysis products, ranging from high, medium and low-pass polysulfone membrane dialyzers, to hemofiltration, dialysate (powder), plasma separators and other over 100 kinds of subdivided products.
