Abstract:
1. A medical fluid system comprising: a medical fluid flow path having a medical fluid supply, a first pump operable in a non-isolated condition to pump medical fluid from the supply to an extracorporeal circuit/blood filtering device and a second pump operable to pull fluid from the blood filtering device; at least one ultrafilter upstream of the blood filtering device; a flowmeter in fluid communication with a rinse outlet of the at least one ultrafilter; an apparatus operable to isolate the blood filtering device from the rest of the medical fluid flow path to form an isolated condition; and a control scheme programmed to (a) receive a volume from an entry by an operator when commencing delivery of the volume and (b) deliver the volume of fluid to the extracorporeal circuit by commanding: (i) the isolating apparatus to isolate the blood filtering device and (ii) the first pump to concurrently deliver the volume of fluid from the medical fluid supply to the extracorporeal circuit.
