The invention relates to an evaluation system of newborn sucking reflex capacity. The system is mainly composed of a core processor (1), a pressure detection sucking nipple (2), a pressure sensor (3),a built-in data model, a display terminal (4), a man-machine interaction interface (5), a power supply module (6) and a patient ID recognition module (11). According to the system, the high-precisionmicro pressure sensor is adopted, the sucking reflex capacity of a newborn baby is dynamically monitored and automatically evaluated, monitored data is scientifically quantized, the consistency of evaluation results is good, the subjectivity of existing sense detection and judgment is avoided, technical gaps of the detection field are filled in, and the system has very high clinical significanceand use value.
