Hemodialyzer
Features
The Filtryzer NF-H is the most advanced high flux PMMA membrane. It offers not only excellent biocompatibility and higher adsorption capacity of proteins like as previous models, but also improved the effect of anti coagulant.
Use
This device is the hollow fiber dialyzer which shall be used in acute or chronic hemo dialysis treatment in order that renal failure patients could remove the excessive water in the body and uremic toxins such as urea, creatinine, phosphate, β2-MG, etc.
