This study examines the performance of disposable drug infuser and proposes an optimum design introducing an elastic body structure. Disposable drug infuser was based on the principal of the recovery force exerted by the elastic diaphragm, as to provide a constant supply of drugs to an out patient who stays away from hospital. It also controls the speed, the duration and the amount of drugs to be released. The existing disposable drug infuser has generally revealed two major problems: one is that the infusion pressure depends on the amount of drug to be infused and the other is that drug infusion decreases. The experiment in this article aims to build and implement the optimum design with respect to the method of fluid-structure interaction, which allows the infusion pressure to remain constant throughout all steps of drug infusion and discharge.
