Analytical model of initial fluid infusion by a microneedle drug delivery system


An analytical model is proposed to calculate the initial infusion of a microneedle array driven by a micropump. By assuming the initial infusion of each microneedle undergoes a spherical expansion, the model is able to calculate the time-varying expansion radius, as well as the flow rate and infusion pressure, provided that the material properties and the… (More)
