Background

During the resuscitation of neonates or the treatment of neonatal respiratory distress syndrome, the neonates are often rescued by tracheal administration, and the following two methods are generally adopted during tracheal rescue:

1. the method has the disadvantages that ⑴ has the interruption of positive pressure ventilation due to the fact that the tracheal catheter port needs to be separated from a resuscitation bag or a respirator when administration is carried out, medicines are injected when ⑵ children suffer from strong spontaneous respiration, the medicines can be sprayed out from the tracheal port, and some medicines are expensive, such as lung surfactant used for treating neonatal respiratory distress syndrome, 120mg of the medicines in each bottle is only 1.5ml, the price is about 3500 yuan, and due to the high price, families often select the lowest dose for medication, so that the medicines are not only economically wasted but also affect the treatment effect after being sprayed out from the tracheal port.

2. The disposable injector is used for puncturing the tracheal catheter for administration, and has the defects that ⑴ the tracheal catheter is not easy to fix due to small size and certain hardness, the puncture needle can damage an operator during puncturing, and the tracheal catheter leaks air due to the puncture needle hole after ⑵ puncturing administration operation.
