A transfusion speed monitor system is designed based on infrared technology with modulation and demodulation. With monitoring the drops and the liquid surface, the system can control the process of transfusion and give a soundlight alarm automatically. Through the experiment, it demonstrates that the monitor has the merits of accurate counting, reliable function, low cost, small volume, low power dissipation and easy handling.
