Extremely premature infant pulmonary vascular development assessment method and device

The invention discloses an evaluation method and device for pulmonary vascular development of an extremely premature infant. The method comprises the following steps: acquiring a physiological data set of the extremely premature infant; the physiological data set comprises a pregnant woman pregnancy factor data subset, an extremely premature infant clinical data subset, a treatment condition data subset, an echocardiogram data subset and a corresponding pulmonary vascular development evaluation reference value data subset; each data subset comprises a plurality of types of measurement data; preprocessing the physiological data set of the extremely premature infant to obtain a standard physiological data set; performing feature category data extraction processing on the standard physiological data set to obtain first data category information and a training data set; performing training processing on a preset vascular development evaluation model by using the training data set; processing the acquired measurem
