In this apparatus, optimum blood purification is carried out while maintaining the circulating blood volume at a prescribed level.Field of SearchIncluding controlling process in response to a sensed conditionDensity or specific gravity sensing Pressure sensing Temperature sensing pH sensing Level sensing Turbidity or optically sensing Electrical property sensing Including geographic feature (e.g., drainage ditch, septic, pond) Utilizing electrical or wave energy (directly applied to liquid or material being treated) With membrane Responsive to material level Responsive to fluid flow WITH GAS SEPARATOR | |
