AbstractThe investigations deal with the mass transfer in simulated biomedical systems. The self-designed Sequential Unit (SU) system imitated different biomedical setups, boundary conditions. The experiments simulated: diffusion chamber (also with two barriers), the transport through the membrane to the blood stream, transport from the stent eluting drug simultaneously to the vessels cells and to the blood stream. The concentrations of substances and the relative mass increases/decreases for SU systems indicate that the order of the curves follows the order of mass transfer resistances. The strong dependence of mass transfer rates versus concentration and type of diffusing substance was confirmed. The calculated drug fluxes, diffusion coefficients, permeation coefficients are convergent with literature. The permeation coefficients for the complex sequential systems can be estimated as the parallel connexion of constituent coefficients. The experiments approved functionality of the SU for investigations in simulated biomedical system. The obtained data were used for numerical verification.
