ABSTRACT:
A method is described herein for automatically rinsing blood back to a patient. The method comprises the steps of pumping dialysate (or, alternatively, saline solution) through a dialyzer into an extracorporeal circuit, and pumping blood in the extracorporeal circuit out the arterial and venous lines back to the patient. Optical sensors monitor the concentration of blood in the arterial and venous lines as the blood is being pumped from the extracorporeal circuit back to the patient. The return flow of blood is ceased when the concentration of blood in the arterial and venous lines drops to a predetermined threshold level, thereby preventing excess fluids from being returned to the patient.
