Abstract：Objective Based on the existing problems of the existing products, we designed an electric nursing device that integrates
“scratching, infusion, medication, and various extended functions”. Methods The control module used STM32 chip to realize the
generation of 8 PWM waves and the introduction of 10 external interrupts. The scratching module was composed of four steering
gears and a transmission device, which could control spatial position and speed. The infusion module consisted of a ground infusion
tank, a gas pump and a liquid level sensor, which could realize infusion control and alarm function. Results The device realized
360° adjustment of the scratching position and four levels of speed control, and also realized the control of the infusion speed and
the safe dressing. Conclusion The multifunctional electric nursing device has the characteristics of low cost, practical function,
simple operation and subsequent expansion.
