This topic uses photoelectric switch to monitor the characteristics of liquid in the infusion tube to transmit the resistance state. When the transmittance in the infusion tube changes, the signal is captured and fed back to MCU by means of the photoelectric switch to distinguish the return of blood to the infusion tube and the termination of transfusion process or other states. While MCU determines the occurrence of blood returning or the completion of medical transfusion, the alarm reminder function will be triggered. And stepper motor rotates to further clamps the infusion tube to stop the dripping of medicine to prevent the emergence of blood returning, air inflow, etc. The study of this system has a certain research and development value and market potential to alleviate the pain of patients and the burden on family members, greatly improving the work efficiency and fatigue of medical staff.
