摘      要：Along with the development of biomedical ergigineering, negative pressure aspirator is more and more widely applied in clinical treatment and patients rescuing. The study of negative pressure aspi- rator is an important goal pursued in emergency treatment, became it can boost aid success. Given this need, this device based on MXT8051 single-chip is developed. The device can use Pulse Width Modulation （PWM） signal to drive the motor of negative pressure pump and it can adjust the motor＇s speed through the Proportional In- tegral Derivative （PID） algorithm to realize the setting negative pressure rapidly, aoctarately and stably. The control requiroemnt is accomplishedthrough the nmn-machine interface. This device has the advantage of simple operation, low cost and good practicability.
