Dialysate supply unit and blood dialyzing apparatus having the same

摘要

Provided is a dialysate supply unit and a blood dialyzing apparatus including the dialysate supply unit for supplying dialysate of a dialysate tank to a hemodialyzer and collecting dialysate passing through the hemodialyzer in an effluent tank. The dialysate supply unit includes a dialysate pump, an effluent pump, a first flow-blocking valve, a second flow-blocking valve, and a flow-blocking valve driver. The dialysate pump connects the dialysate tank and the hemodialyzer and the effluent pump connects the hemodialyzer and the effluent tank. The first flow-blocking valve alternately blocks a dialysate outflow tube connecting the hemodialyzer and the dialysate pump and an effluent inflow tube connecting the hemodialyzer and the effluent pump. The second flow-blocking valve alternately blocks a dialysate inflow tube connecting the dialysate pump and the dialysate tank and an effluent outflow tube connecting the effluent pump and the effluent tank. The flow-blocking valve driver drives the flow-blocking valve.
