Abstract：Objective To design a kind of low-cost and high-safety infusion alarming device. Methods With the adoption of the principle of infrared induction, the double infrared induction infusion alarming device was designed, which consisted of five parts, including the infrared sensor, signal amplifier system, microcontroller unit, control unit, sound and light alarming unit as well as the battery unit. The working principle of the alarming device was to use double infrared sensing device to detect liquid infusion in the pipeline. The detected signals by either of the two infrared could be detected once the infusion ended, then leading to the change between the two infrared so as to trigger the alarm device. At the same time, it also could prevent bubbles into the body during the process of infusion. Results According to the experiment results, the infusion alarming device showed its high-sensitivity, low-cost and easy-to-use advantages. Conclusion The design of the infusion alarming device was safe and convenient to use, which had practical effectiveness.
