Abstract
An artificial kidney capable of operating without a dialysis machine for the treatment of chronic renal failure in discontinuous sessions consisting essentially of: PA0 a. a source of a prepackaged dialysis liquid; PA0 b. a hemodialyzer with a high permeability membrane continuously traversed by the blood and the dialysis liquid; PA0 c. means for collecting the used dialysis liquid and possibly the ultrafiltrate; PA0 d. means for measuring the patient's variations in weight; and PA0 e. possibly means for injecting a sterile and apyrogenic liquid into the extracorporeal blood circuit. This artificial kidney is particularly intended for operating in a non-hospital environment.
