Furthermore, in order to be a certified infusion operation, it is required that the pump can operate if the power cuts out or is even unplugged and can detect the change of flow rate or pressure even if the flow is blocked or kinked, taken backward and finished when an infusion bag or pump is empty. An IPMC has characteristics both as an actuator and sensor. In addition, it is easy to control the frequency (flow interval) and flow rate by changing of the electric signals with low voltage. We propose a new miniaturized disposal IPMC infusion pump with embedded computer controlling, which can control a micro flow with a low power source, batteries.
