[0003] These medical devices are all provided with an inflatable cuff (also known as: air bag or balloon), which is placed in the main trachea, bronchus or epiglottis area of the human body, and plays the role of fixing and sealing the airway; but a certain proportion of these devices will still have slow air leakage in clinical use, resulting in the air bag sealing is not tight, and the sputum and the like flows into the trachea / bronchus to cause pulmonary infection and other complications. In use, the nurse and doctor need to check the pressure state of the cuff regularly to avoid the air bag sealing being not tight. This greatly increases the workload of the nurse, and the judgment method of the nurse is mostly to determine the state of the air bag by pinching the hardness of the indicating air bag, and the judgment result is often inaccurate, and once the manual pressure compensation is too large, it will cause great damage to the airway mucosa of the patient.
