Premature infants and low birth weight infants are immature in sucking-swallowing-breathing coordination function, not only need to complete nutrition intake through tube feeding through an indwelling gastric tube, but also need to maintain respiratory function through ventilator assisted ventilation (gastrointestinal distension is caused by invasive assisted ventilation and noninvasive assisted ventilation), and are immature in gastrointestinal function, and are easy to have feeding intolerance performances such as gastric retention, abdominal distension and gastroesophageal reflux. In the case of a critically ill newborn, the infant also develops feeding intolerance due to ischemia and hypoxia caused by the damage of organ functions.

The nutrition substances are required to be taken in by tube feeding for the infants such as premature infants and infants with low birth weight, and the feeding is carried out gradually in the early stage by a trace feeding mode to achieve full-oral feeding. At present, the feeding mode of the premature infant and the low-birth-weight infant in clinic is to close the stomach tube after each feeding, and open the stomach tube to the next feeding after 30 min-1 h (the stomach tube is opened after 30 min-1 h to prevent aspiration pneumonia or asphyxia caused by gastroesophageal reflux when the stomach tube is closed clinically, the stomach tube is communicated with the stomach tube through atmospheric pressure when the stomach tube is opened, and when the pressure in the stomach is increased, the liquid in the stomach can flow back into the container to achieve the effect of preventing reflux).

The existing tube feeding method comprises the following basic steps: the piston of the injector is taken out, milk is injected into the needle cylinder part of the injector, then the piston is taken out after being pressed, the milk flows into the stomach tube for feeding through gravity, the injector cannot conveniently and quickly meet the frequent operation of closing and opening the stomach tube after feeding clinically, the problem of piston placement exists after the piston is separated from the injector, the injector has a large opening and cannot be hung, when the stomach tube is closed after feeding, the stomach tube and the injector need to be separated, the stomach tube can be closed by reducing the position of the piston, and the operation is complicated; when the stomach tube is opened, the reflux liquid in the injector is easy to overflow due to unbalanced or overfull placement, and the requirements of hospital infection prevention and control are not met.
