Background

Tube feeding refers to a method of injecting fluid diet, medicine, water and the like required by a patient into the gastrointestinal tract through a catheter, which is a gastric tube. Premature infants with low gestational age (gestational age < 34 weeks) are generally swallowed and sucked, and cannot achieve full-intestinal feeding by means of autonomous feeding, so stomach tube feeding is required to achieve the purpose. However, after partial digestive tract operation or in children with poor digestive absorption function, not only a stomach tube needs to be placed, but also a micro pump needs to continuously pump milk in a small amount to promote digestive absorption. And present clinical stomach tube and micropump of using have a great deal of problems:

at present clinical stomach tube commonly used has singly, it is two, three chamber pipes, although the lumen is more, but mostly inject into the medicine, food and drainage effect, the usage is comparatively limited, the defect is more, need take empty needle after injecting into medicine or food and inject warm water once more or the air washes the pipe, in order to avoid the interior residual substance of pipe to breed the bacterium, but also an extra extravagant syringe, and whole journey needs nursing staff to come the operation, and so not only comparatively loaded down with trivial details, but also hardly control the speed of infusing of milk accurately, speed is too fast or too slow can lead to the neonate to be uncomfortable.
