Abstract
A multipurpose hemofiltration system ( ) and method are disclosed for the removal of fluid and/or soluble waste from the blood of a patient. The system ( ) continuously monitors the flow rates of drained fluid, blood, and infusate. When necessary, the pumping rates of the infusate, drained fluid and blood are adjusted to remove a preselected amount of fluid from the blood in a preselected time period. A supervisory controller ( ) can monitor patient parameters, such as heart rate ( ) and blood pressure ( ), and adjust the pumping rates accordingly. The supervisory controller ( ) uses fuzzy logic to make expert decisions, based upon a set of supervisory rules, to control each pumping rate to achieve a desired flow rate and to respond to fault conditions. An adaptive controller ( ) corrects temporal variations in the flow rate based upon an adaptive law and a control law.
