The highly mobile mobile medical unit relies on the road network coverage to achieve full accessibility. It is equipped with standardized medical testing equipment and the IoT cloud platform, and can complete the data collection and storage of core testing items such as blood routine, blood biochemistry, urine routine, liver function, electrocardiogram, digital X-ray (DR), and ultrasound imaging on site. Through 5G/IoT technology, real-time transmission and cloud analysis of test data are achieved, and health risk assessment and personalized guidance are carried out simultaneously. For high-risk groups and chronic disease patients screened out, the system automatically incorporates them into the regional health information platform, triggering a standardized hierarchical management model to form a closed-loop service system of "testing-assessment-intervention".
