Microcontroller-based Contrast Agents Dedicated Pump Control System Design And Implementation

Hospital injection of contrast agent widely used. Currently a varietyof hospital radiology angiography, contrast agent from injection to fullinspection, imaging film process, are in the radiation room, for up totens of minutes. To long-term work of doctors in the radiology departmentcaused great harm. Urgent need to push on now to start the X-ray contrastagent injection method to be updated.This design of medical imaging agents dedicated pump control systemto control the stepper motor microcontroller core, fully automatic,multi-compartment-specific contrast agent remotely controlled pumps,instead of the original complete manual contrast injection. SCM is thecore system control, from micro-limit switch, the sensor detects thesignal and remote control signals received are processed by themicrocontroller to determine the output for the digital display andstepper motor drives and other control signals. The control system isdesigned to achieve a long-distance medical compartment remote control,with the amount of liquid in the process of imaging the two shows, canbe controlled from any two stops and the contrast agent flow speed andother functions, and a variety of sound and light alarm status and so on.Reduce the labor intensity of medical personnel, to avoid the X-rayradiation on staff, improve efficiency, reduce the patient’s pain.In the overall program design, to ensure the system can achieve thedesign requirements and the stability of the premise, taking into accountthe system’s utility and reliability of the circuit system is optimized,and the system hardware design and control requirements, design write themain program the microcontroller, stepper motor drivers, key controlprocedures, travel and limit control procedures, digital tube displayprogram modules. Part of the hardware and software also features a varietyof anti-jamming measures necessary.
