Abstract-Along with the development of biomedical engineering , negative pressure aspirator is more and more widely applied in clinical treatm ent and patients rescuing. The study of negative pressure aspirator is an import ant goal pursued in emergency treatment, because it can boost aid success. Given this need, this device based on MXT8051 single-chip is developed. The device c an use Pulse Width Modulation (PWM) signal to drive the motor of negative pressu re pump and it can adjust the motor′s speed through the Proportional Integral D erivative (PID) algorithm to realize the setting negative pressure rapidly, accu rately and stably. The control requirement is accomplishedthroug h the man-machine interface. This device has the advantage of simple operation, low cost and good practicability.
Key words-MXT8051 single-chip; PID algorithm; motor co ntrol; ilegative pressure aspirator
