ABSTRACT:
A proportioning system is provided for mixing dialysate used in an artificial kidney machine. A first conduit carries concentrate solution in a recirculating loop pattern. A second conduit carrying water intersects the first conduit. At the point of intersection, the first conduit has an orifice for discharging concentrate into the flowing water. Concentrate is supplied to the first conduit through a supply line immersed in a storage jug. The supply line has a pressure-operated check valve through which concentrate passes only when required.
