Hemodialysis machine is a machine used for dialysis to filter the patient's blood to remove excess water and waste when the kidney is damaged, dysfunction or loss. The dialysis machine itself can be considered an artificial kidney. Dialysis concentrate and dialysis water are prepared into qualified dialysate through the dialysate supply system, and the patient’s blood drawn from the blood monitoring alarm system is used for solute dispersion, permeation and ultrafiltration through the hemodialyzer.
