HEMODIALYSIS APPARATUS UTILIZING PULSATING PUMP

摘要

PURPOSE: Provided is a hemodialysis apparatus utilizing a pulsating pump which has a simple structure, can be manufactured at a low cost and has a relatively high hemodialysis function and suppress haematolysis and thrombosis phenomenons by decreasing a pressure applied to a blood pump. CONSTITUTION: The apparatus(1) comprises a dialyzer(9) divided into a blood chamber(3) and a dialysate chamber(5) by a semipermeable membrane(7), vessel coupling units(17-1,17-2) mounted at a blood supply line(11) and a blood return line(13) respectively, a dialysate circulator(18) circulating a dialysate to the dialysate chamber(5) of the dialyzer(9) via a dialysate circulating line(15) and a blood circulating pump(21) disposed at the blood supply line(11) or the blood return line(13) for generating a blood flow, wherein the blood circulating pump(21) includes: a pair of supply and return pulse chambers(32-1,32-2); a reciprocating movable body(50); and a non-return valve.
