Visual tracheal intubation guiding device

The invention relates to the technical field of medical instruments, and discloses a visual tracheal intubation guiding device which comprises a guide tube, a display device, a camera, a light source and an end-expiratory carbon dioxide concentration detection device, the guide tube is arranged in a tracheal intubation in a penetrating mode, and real-time images of a trachea structure are transmitted to the display device through the camera; the carbon dioxide concentration distribution in front of the guide pipe is detected through the end-expiratory carbon dioxide concentration detection device. If the interior of the trachea is not shielded and the visual field is clear, the camera displays the trachea structure to help medical staff to perform intubation, if various conditions such as tissue swelling, secretions and bleeding occur in the trachea, the camera cannot display the trachea structure, and the end-expiratory carbon dioxide concentration detection device can detect the distribution of the carbon d
