ABSTRACT
Controlling and diagnostic processes in the bioengineering artificial clearance systems despite of the procedures applied, their functional use and design seem to occur in the artificial organs, each of them consists of controlling and actuating processors ensuring their homogeneous (material, energy-producing, informational) or combined interaction with the patient's body. Centralized control over artificial clearance is proposed by using universal controlling processes which are informationally connected with the operator, the central computer and other controlling processes of the bioengineering system.

To evaluate the clinical efficiency of hemodialysis and ultrafiltration monitoring, the consumption and volume of an ultrafiltrate should be timely measured. Balance measurement of changes in a patient's body weight during hemodialysis has a significant methodological error made by patient's body weight changes unassociated with ultrafiltration.

The clinical efficiency, safety and accessibility of a lot of artificial blood clearance procedures are provided by the versatility of equipment operational capacities, computerization, automatization, expendable blood-conducting elements, higher independence through the electrochemical regeneration of a dialyzing solution, a reduced range of the hardwares used and their simplified designing implementation. A clearance technique-invariant pattern of polyblock of technical equipment with a universal perfusion unit wherein perfusion is accompanied by centralized equipment control has been proposed and introduced into practice.
