Abstract
A hemofiltration system is provided in which ultrafiltrate is purified by reverse osmosis for reinfusion. Non-sterile infusate concentrate is dialyzed into the purified ultrafiltrate and combined with cleared blood which is returned to the patient. In another system, a hemofilter is used to sterilize essentially pure, non-sterile water for dilution of sterile infusate concentrate, then the hemofilter is used to filter blood, the infusate concentrate being combined with cleared blood for return to the patient.
