Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a dental brace type tracheal intubation tooth pad fixing structure. Background Art

[0002] Endotracheal intubation is a technique of inserting a special endotracheal tube into the trachea through the glottis. It can effectively manage the airway and is widely used in patients with emergency cardiac and respiratory arrest. The operation process is usually to insert a traditional bite pad between the patient's upper and lower incisors after confirming that the intubation is successful, and fix it in parallel with the endotracheal tube to prevent the patient's unconscious biting action from blocking the endotracheal tube and to limit the endotracheal tube. The current bite pad device is fixed by the patient's teeth bite, but when used for unconscious patients such as those suffering from cardiac and respiratory arrest and after anesthesia, such patients cannot bite with their teeth independently, making the device difficult to apply to such patients. In addition, the current bite pad size is fixed, which is difficult to adapt to different patients and has low comfort. Utility Model Content
