BENEFICIAL APPLICATION OF HOLLOW FIBER WITH FIN TO HIGH PERFORMANCE MEMBRANE DIALYZER

Abstract

We developed 6μ thickness hollow fiber (HF) with fin for hcmodialyzer (D) which could not be applied to D by its fragility without the attachment of fin. D composed of 6μ HF showed about 20% higher dialysis efficiencies than those of ordinary 8μ thickness HF D. Neither coagulation nor leakage was observed in the 6μ HF D. The attachment of fin to HF with high molecular cut off point also increased dialysis efficiencies of low molecular substances, which were not removed so effectively by the HF without fin. These results indicate that the attachment of fin to HF increases the dialysis efficiency not only by reducing the dialysate side mass transfer resistance but also by applying the very thin HF effectively. HF with fin can be applicable for widespread high performance D.
