Background
About 180 million premature babies are born in hospitals each year in China. Premature infant refers to an infant with a birth weight of less than 2500 grams, less than 37 weeks of gestational age. An ultra-low birth weight infant refers to an infant with a birth weight of less than 1000 grams. The umbilical vein and artery are the vital lines connecting the fetus to the mother, and in general, the umbilical cord is ligated after birth of the newborn, and the most primitive nutrient channel is completely disabled. Premature infants are extremely prone to multi-system dysfunction and metabolic abnormalities within one week after birth, and need to take blood repeatedly to monitor various physiological indexes and give liquid and energy support in an early stage. However, since the blood vessels of the newborn, especially the premature infant, are fine and the skin is thin, the ventricular canals have abundant blood capillaries, the newborn is greatly injured by repeated insertion and blood drawing, and the insertion of the needle is more difficult due to blood stasis and swelling caused by repeated insertion.
