[0002] The endotracheal intubation includes a trachea, a cuff, and a stylet. The endotracheal intubation is an important way to establish an artificial airway to ensure unobstructed breathing and maintain the body's oxygen supply. In clinical work, we can find that during the intubation process, the cuff, as an important part of the endotracheal intubation to ensure airtightness, when checking the airtightness, it is found that by simply pumping the cuff, the verification is not obvious. And during intubation, the cuff often comes into contact with and rubs against the teeth to a certain extent, which may cause the teeth to cut through the cuff, resulting in air leakage during mechanical ventilation, leading to secondary intubation and other injuries. In addition, for tracheal drug administration, multiple operations may cause certain irritation and damage. Therefore, there is an urgent need to set up an endotracheal intubation cuff outer shell that can quickly check the airtightness of the cuff and prevent the external environment from polluting the cuff, so as to improve the safety and stability of the cuff use.
