Abstract

The application and working principle of piezoelectric insulin pump are analyzed. The design of using piezoelectric elements to drive the push type insulin pump was proposed. A two serial chamber piezoelectric pump is selected as drive resource and the injector pushed by piezoelectric pump is used to achieve transporting the liquid medicine accurately. The experimental device are designed and researched. The designed piezoelectric insulin pump can transport the liquid medicine and has the self-lock ability meanwhile. Even when the output back pressure is high, the back flow of liquid will not happen. The test results showed: with 180 Hz driving signal, the flow of pump can reach 37.5 Â¿L.
