In recent years, the incidence rate of premature infants in China has been on the rise year by year, and the incidence rate of lung surfactant supplement in the trachea and emergency medicine administration in emergency treatment is continuously increased due to premature lung development and various high-risk factors of the premature infants. The mode and route of administration within the trachea is also constantly being updated.
The traditional mode of intratracheal administration is open administration, the tracheal catheter and the resuscitation air bag need to be separated intermittently to administer the medicine for several times, namely, after the tracheal catheter is separated from the resuscitation air bag, the medicine is administered from the connecting end of the tracheal catheter connected with the resuscitation air bag, the supply of oxygen pressure can be interrupted due to the separation of the resuscitation air bag, and the intermittent separation of the tracheal catheter and the resuscitation air bag can interrupt the supply of oxygen pressure for the infant patient, so that alveolus is easily caused to collapse, and the compliance of the lung and the pathological change of the lung are reduced.
In addition, when the lung surfactant or other first-aid medicines are administered in the trachea, under the traditional open mode administration (namely, after the tracheal catheter is separated from the resuscitation air bag, the medicines are administered from the connecting end of the tracheal catheter connected with the resuscitation air bag), the choking cough reflex of the sick child easily seeps the medicines from the connecting end of the tracheal catheter connected with the resuscitation air bag, so that the medicines are wasted, the medicine is not used sufficiently, and the treatment effect is influenced.
The existing bending recoil integrated intratubular medicine feeding device can solve part of the defects of the traditional mode of medicine feeding.
