The flexible covering pad can also be used as an aid in all devices that utilize differences in light penetration into tissue to directly or indirectly locate or potentially have this effect, increasing operator success. Secondly, the device is provided with a storage box, the length of the lead of the positioning device can be adjusted when the device is used, the lead can be stored in the box body when the device is not used, the lead can be prevented from knotting and winding with other lines, and the storage and the use of the lead are facilitated; the storage box can store the positioning device, so that the positioning device can be stored and kept conveniently and prevented from being damaged. Then, the device can be wirelessly connected with a computer, cannot be wound with other lines, and is convenient for an operator to use. Finally, this device is equipped with assorted aseptic protection bag, and it is convenient to use, is favorable to preventing cross infection, and does not influence the accuracy of gathering the model. Therefore, there is a need for an external optically indexed airway tube positioning device that addresses the above-mentioned problems.
