Novel neonate trachea cannula

Technical Field

The utility model relates to the field of medical treatment, in particular to a novel neonate trachea cannula.

Background

The technology of placing a special endotracheal tube into a trachea through a glottis is called trachea intubation, the technology can provide optimal conditions for unobstructed airways, ventilation and oxygen supply, respiratory tract suction, prevention of aspiration and the like, and the emergency trachea intubation technology becomes an important measure in the process of cardio-pulmonary resuscitation and emergency critical patient rescue accompanied with respiratory dysfunction. The trachea intubation is an important rescue technology commonly used in emergency treatment work, is one of the most widely, most effective and most rapid means applied in respiratory tract management, is a basic skill which must be mastered by medical staff, plays a vital role in rescuing the life of a patient and reducing the fatality rate of the patient, can timely suck out tracheal endocrine matters or foreign matters, prevent the foreign matters from entering respiratory tracts, and prevent whether the patient is anoxic and carbon dioxide retention trachea intubation is timely and directly related to the success or failure of rescue, whether the patient can safely transport the trachea intubation and the prognosis condition of the patient.

On the basis of the technical conditions of the existing trachea cannula, a plurality of defects still exist in the aspects of application range and convenience, and the breathing machine needs to be disconnected for assisting ventilation when sputum suction and administration are carried out, so that alveoli are trapped when medication or sputum suction occurs, and the lung of a newborn is damaged; administration from the air inlet end of the tracheal cannula easily causes choking, thus causing the waste of the drug (6000/branch alveolar surfactant); in the prior art, the administration catheter is designed in the wall of the tracheal cannula body, the inner diameter of the tracheal cannula is increased, the airway resistance R is in a proportion of 1/R4 according to a formula, the thinner the inner diameter of the tracheal cannula is, the larger the resistance is, so that the ventilation resistance is increased, the effective ventilation of the lung is influenced, and the inconvenience is very high.
