Filtryzer BG

Filtryzer BG(Catalog)


New improved PMMA membrane is introduced into the Filtryzer BG, which has higher porosity and unprecedented adsorption capacity of proteins. With this techinology, the permiability of small molecules, and permiability of higher molecular weight proteins has been improved. Moreover, it features efficacy in amelioration of renal itching in hemodialysis patients.


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 uric toxins such as urea, creatinine, phosphate, β2-MG, etc.
