Background
Tracheal intubation is a common clinical technique for clinical anesthesia, emergency resuscitation, and critical patients. At present, due to popularization of the video laryngoscope trachea cannula technology, the implementation difficulty of the trachea cannula technology is effectively reduced, and a plurality of patients are effectively treated. However, there are also some direct or indirect complications of the tracheal intubation itself, such as: choking after intubation, tissue injury, cardiovascular system interaction, laryngeal spasm or bronchospasm, and throat pain after extubation.
Among these, cardiovascular system sympathologies, also known as intubation stress, are particularly common. In particular, blood pressure rises and tachycardia reactions during laryngoscope and intubation procedures, and can induce arrhythmias. The intubation stress response may have disastrous consequences in patients with coronary sclerosis, hypertension, arrhythmia, and tachycardia.
For the above cases, clinically, perfect surface anesthesia in the throat and trachea is often used to inhibit the generation and conduction of nerve impulses or opioids are used intravenously to inhibit cardiovascular reactions. However, the combination of surface anesthesia with opioid is a good option because of the large volume of opioid used while also inhibiting patient circulatory stabilization. Therefore, the use of deeper tingling to minimize laryngoscope handling time, in combination with pharyngeal and intratracheal spraying of local anesthetics, is an effective means of reducing stress response.
In order to facilitate the implementation of the surface anesthesia of the oral cavity, the pharyngeal portion and the airway spray, and simultaneously reduce the possibility of cross infection among different patients.

6) In the step 4), the second anesthetic channel 4 is started by pressing a start button on the video laryngoscope, and the second anesthetic channel 4 is sprayed;
7) In the step 4), the video laryngoscope detects the initial position of entering the oral cavity, and the second anesthesia passage 4 is automatically started to spray;
8) The first anesthetic channel 3 can be connected with a temporary oxygen source to spray oxygen to the air passage;
9) Pushing the anesthetic tube 2, the connection plate 21 moves between a set of positioning latches 122, so that the anesthetic tube 2 moves in the first anesthetic channel 3.
Example two
In another self-destroying structure of the dual-channel anesthetic laryngoscope blade, as shown in fig. 8, a convex portion 113 is disposed on an inner wall of the first side wall 11 and the second side wall 12, which is close to the first opening 16, an elastic rubber pad 114 is disposed on the convex portion 113, a clamping portion 115 is disposed on the elastic rubber pad 114, and the clamping portion 115 can be clamped with an outer wall of the video laryngoscope.
The foregoing is merely a preferred embodiment of the invention, and it should be noted that modifications could be made by those skilled in the art without departing from the principles of the invention, which modifications would also be considered to be within the scope of the invention.
