Objective： To design one kind of medical infusion pump. Methods： Based on single-chip microcomputer, 89C52, use the stepper motor to drive the semi extrusion micro flow pump. Results：During the infusion it can real-time monitor the block and bubble in the pipeline and alarm. It can accurately control the transfusion speed and infusion volume. With friendly man-machine interface it can display real-time infusion parameters and alarm signals. Conclusion： The infusion pump system has high precision and reliability, perfect function, and it is easy to use. Clinical practices show that it can effectively reduce the workload of the clinical nursing staff and improve work efficiency. It has high application value.
