[Modeling of the structure of hemodialysis apparatuses]

By taking into account the general principles in the design of extrarenal blood clearance apparatuses, all existing hemodialysis apparatuses (HDAs) are classified by the transportation of the controlling medium, by the degree of automation, by the control of amounts of the liquid removed from the patient, and by their connection to the latter. The proposed classification of HDAs and a model of the structure of dialysate units showed the unity of principles in designing HDAs irrespective of the specific features of their design, which may be used to ensure the versatility, reproducibility, technological effectiveness, convenience in application, and efficiency of the apparatuses designed.
