Background technique

Endotracheal intubation is a special endotracheal tube inserted into the trachea through the nose and throat. This technology is very important to ensure effective ventilation for critically ill patients, especially when severe neonatal asphyxia requires resuscitation. Endotracheal intubation It is a key step for successful rescue. If medication is required in the trachea, positive pressure ventilation needs to be terminated. Most of the medication tubes currently on the market are inconvenient to use. The existing medication tubes are inserted into the trachea through the nose and throat, but during the medication operation, The catheter inserted into the nasal cavity will shake or fall off due to external factors, which can easily cause damage to the newborn. Moreover, the liquid delivered through the catheter flows into the newborn's body, which will cause the newborn to absorb the liquid. Slow and easy to reduce the efficiency of treatment, and the amount of administration is difficult to control. If administered too fast, powdered or liquid drugs can cause problems such as choking of newborns. The current drug administration technology requires external human operation. Auxiliary administration can easily cause infection to patients. In order to solve the above problems, we provide an intratracheal drug delivery device dedicated to neonatal ventilators.
