Background

The tracheal tube is suitable for establishing an artificial airway of a patient in clinic, and is used for mechanical ventilation, surgical anesthesia or cardiopulmonary resuscitation and the like. The inflation size and the stability of the inflation quantity of the air bag on the tracheal catheter determine whether the respiratory function support technology is successful. The tightness of the endotracheal tube and the patient's airway is critical to the positive pressure ventilation of the ventilator and to prevent aspiration of oropharyngeal secretions. The air bag is inflated too much to press the tracheal tissue to cause ulcer or the air bag is broken, and the air is not inflated enough to leak air to influence the work of the breathing machine or cause aspiration. At present, most medical care personnel touch the air sac with hands and communicate with the air sac by experience to indicate the inflation quantity of the air sac when using the trachea cannula to judge whether the air sac is damaged or not when the trachea cannula is inserted into the trachea position of a patient through the mouth. The judgment error is difficult to avoid completely depending on experience and hand feeling, the hand feeling and the judgment standard of medical staff are different, and particularly, the insufficient inflation or air leakage of the air bag cannot be found in time, so that the failure of the respiratory support is caused, and the serious respiratory failure and even death of the patient are caused. Because the air bag is not inflated enough, the leakage of oropharyngeal secretions to the lower respiratory tract is an important reason for the occurrence of the respiratory pneumonia, is a worldwide problem and has extremely high clinical mortality. In clinical work, the commonly used balloon pressure monitoring techniques mainly include: the monitoring method of the air bag pressure gauge, the air bag touch judging method and the minimum sealing pressure method are based on the application of the air bag pressure monitoring technology, and the air bag pressure is mostly measured discontinuously. However, the pressure of the air bag is not constant, and is influenced by various factors such as cough, sputum aspiration, lung compliance, intra-thoracic pressure of an air passage and a chest, the use time of an artificial air passage, the temperature difference of air inside and outside the air bag and the like, and is in dynamic change. Therefore, dynamic monitoring of the pressure of the tracheal catheter balloon is urgently needed.
