发明名称 Device and method for preparation of substitution solution
摘要 Apparatus and methods for providing sterile substitution solutions from a dialysis fluid used in connection with the treatment of a patient's blood in an extracorporeal circuit are disclosed. The apparatus includes pumps or valves for comparing the flow of fresh dialysis fluid prior to treatment and after treatment of a patient's blood and a throttle which divides the fresh dialysis circuit into a positive pressure portion and a negative pressure portion, a sterile filter including a membrane disposed in the positive pressure portion of the dialysis circuit, and a valve for controlling the pressure in the positive pressure portion to pass a predetermined amount of the fresh dialysis fluid through the membrane in a sterile filter to provide a predetermined amount of the sterile substitution solution for addition to the extracorporeal circuit.
