Toraylight NV

Tolaylight NV (Catalog)


The name of material of fiber of Toraylight is "HYDROLINK membrane". It has excellent biocompatibility and dialysis performance by using "new membrane reforming technolgy" forced on "adsorbed water".
The Toraylight NV is a high flux dialyzer, it offers higher level of removal performances for the uremic toxins from small molecule solutes to low molecular weight proteins such asβ2-MG.


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.
