Abstract
Disclosed is a gravity flow fluid balancing system that includes an infusion line to transport an infusate from an infusate supply to a patient's body and an ultrafiltrate line for transporting ultrafiltrate from the body to an ultrafiltrate reservoir. The infusate and ultrafiltrate reservoirs are each connected to a load cell. The load cells are, in turn, connected to a control unit which compares the readings received from the load cells. A clamp, which is controlled by the control unit, controls the flow out of the infusate reservoir into the patient's body. Control of the clamp and fluid flow through the system can be regulated on a weight change basis (infusate - ultrafiltrate) or on an infusion basis.
