With the continuous innovation of digital technology in my country at this stage and the design of medical imaging technology systems, the depth and breadth of the development of digital medical imaging technology have been greatly expanded. This paper focus on application of medical images in breast milk smearing of the umbilical nursing for full-term newborns.To explore the effect of breast milk application in umbilical nursing of full-term newborns.596 full-term newborns were divided into three groups: Experimental Group, Control Group A and Control Group B, Experimental Group A treated with breast milk, control group a treated with 75% alcohol, and control group B treated with 37 ~ 42°C warm boiled water, the time of umbilical cord abscission, infection and other complications were compared among the three groups. The process was recorded by images.According to the images, compared with the Control Group A and B, the experimental group significantly shortened the time of umbilical cord shedding, the difference was statistically significant (p < 0.001).The application of breast milk in umbilical region of full-term neonates can reduce the time of umbilical cord abscission without increasing the incidence of Omphalitis.
