Abstract
With the continuous development of intelligent control, clinical research automation
equipment has become a focus of medical devices. It can reduce the pressure of staff,
improve the working efficiency of medical staffs. Intravenous infusion is a common
clinical treatment ， the treatment effect in the vein of the input,this topic is the design
method of the intelligent infusion system, the scheme is based on AT89S51 control. This
system operation is simple, started fast, has an alarm function and convenient centralized
control, is of great significance in modern medical enterprise，promote the development of
intelligent medical business automation，is conducive to improving the quality of medical
care.
The main function of this subject: the circuit for collecting the droplet velocity，droplet
velocity can be set and compared, can display the drop speed and the rest of the infusion
time; can set up their own drop speed; in the infusion of remaining liquid volume is lower
than the set value, the automatic alarm, or infusion process there are special circumstances
