Optimization of valveless micropump for drug delivery

Abstract

With controlled drug delivery system, appropriate and effective amount of drug can be precisely delivered at appropriate time by a micropump. This is achieved with the use of diffuser and nozzle elements that eliminate the need for valve mechanism simplifying the micropump design and fabrication. A preliminary valveless micropump prototype has been demonstrated and the systematic optimization to improve the performance at low Reynolds number (Re <; 100), typical in drug delivery system, is presented here.
