Separation of Cells From Plasma by Means of Ultrasonics

This paper presents an analysis of use ultrasonic standing wave in cell separation from bodily fluids based on the example erythrocyte plasma. It describes movement red blood cells plasma under influence acoustic field (whose forces result interaction with as vibrating medium) and resistance Stokes’ Oseen’s approximation. The general properties solutions motion equation are given. for parameters which interesting terms practical applications medical diagnostics discussed. Time constants transportation to regions stable equilibrium estimated. formulas determine time needed obtain assumed concentration increase nodes and/or anti-nodes derived.
