[Relationship between the rates of blood and dialyzing solution flow and determination of the efficiency of the "artificial kidney" dialyzing apparatus].
A mathematical model of the process of dialysis and of dialyzer is described. In this model it is presumed that the blood and dialyzing solution are stationary and homogenous, the diffusion through the film proceeds separately for each of the components (urea, creatinine, etc), the rate of the substance migration is proportional to the difference in the concentration of the substance on both sides of the film, the processes of the substance migration through the film do not affect the flow of the dialyzing solution and of the blood, the concentration of the components partaking in the dialysis is constant across the thickness of the fluids layers and along the breadth of the dialyzer. Recommendation on the selection of correlation for the dialyzing solution and blood flow rates are given and the influence of the film permeability on the dialyzer's clearance is determined.
