For the purpose of diagnosis, prevention, monitoring, treatment, or amelioration of a disease; diagnosis, monitoring, treatment, mitigation, or functional compensation of injury; examination, replacement, regulation or support of a physiological structure or physiological process; support or maintenance of life; controlling pregnancy; by examining a sample from a human body, information is provided for medical or diagnostic purposes.

When the trachea cannula operation is clinically carried out, the tightness of the air bag needs to be proper, if the air inflation quantity of the air bag is too large, the air bag is pressed too high to influence the mucous membrane of the airway, and the clinical research result shows that, when the balloon pressure exceeds 30cmH2O (1cmH2O ═ 0.098KPa), the mucosal capillary blood flow begins to decrease, when the pressure of the air sac exceeds 50cmH2O, the blood flow is completely blocked, the tracheal mucosa is pressed for a certain time, the tracheal mucosa is ischemic and even necrotized, and tracheoesophageal fistula can occur in serious cases, on the contrary, if the air bag is not inflated enough, air leakage, aspiration and the like are caused, the domestic and foreign investigation results show that most anaesthetists and emergency doctors still adopt the finger touch experience to judge whether the air bag is inflated enough, this tends to cause over-inflation, with bladder pressures even as high as 210mmHg (1 mmHg-0.133 KPa), even experienced physicians are no exception, and for this reason we propose an endotracheal tube that can monitor balloon pressure.
