Requirement Description Hemodiafiltration Units are extracorporeal blood purification units used in renal replacement therapy and designed to combine diffusion and convection to remove uremic toxins, excess electrolytes, and fluid from blood. The unit operates by withdrawing blood from the patient through a vascular access line and circulating it through a dialyzer containing a semi-permeable membrane; small solutes diffuse across the membrane into a countercurrent flow of dialysate, while larger molecular weight substances are removed via convective transport driven by transmembrane pressure, with a controlled volume of plasma water filtered and replaced by sterile substitution fluid. Core components include a blood pump that regulates extracorporeal blood flow, a dialyzer (filter cartridge) that facilitates solute exchange and ultrafiltration, a dialysate delivery system that prepares and circulates electrolyte-balanced fluid, a substitution fluid system that infuses replacement fluid either pre- or post-filter, pressure monitors and sensors, air detectors and venous clamps, anticoagulation systems to prevent clotting within the circuit, and a central control unit with software that coordinates flow rates, pressures, fluid balance, and treatment parameters.
