[0025] In view of the fact that the existing video laryngoscope blade may affect the intubation process because the patient's secretions block the field of view, and it is impossible to anesthetize the throat and reduce the throat discomfort caused by tracheal intubation, the utility model proposes a video laryngoscope blade surface anesthesia device, referring to Figure 1 , Figure 1 This is a schematic structural diagram of an embodiment of a video laryngoscope blade surface anesthesia device of the utility model. The video laryngoscope blade surface anesthesia device of the utility model will be described in detail below in conjunction with the accompanying drawings.

[0026] In the embodiment of the present utility model, Figure 1 As shown, the video laryngoscope blade surface anesthesia device 100 includes a video laryngoscope blade body 1, a laryngeal anesthesia tube passage 2, and a passage nozzle 21. The longitudinal section of the video laryngoscope blade body 1 is arc-shaped; the laryngeal anesthesia tube passage 2 is arranged on the video laryngoscope blade body 1; and the passage nozzle 21 is arranged at the front end of the laryngeal anesthesia tube passage 2.

[0027] The technical solution of the utility model is to set a laryngeal anesthetic tube passage 2 on the video laryngoscope blade body 1. The laryngeal anesthetic tube passage 2 can clean the patient's secretions. At the same time, the laryngeal anesthetic tube passage 2 is also connected to a syringe filled with anesthetic drugs to perform anesthetic drug pretreatment in the throat. It not only solves the trouble that the medical staff's field of vision is blocked by secretions during the intubation process, but also improves the comfort of the patient's throat after intubation, thereby improving work efficiency and patient comfort.

[0028] It is understandable that the video laryngoscope blade surface anesthesia device 100 provided by the utility model is mainly suitable for tracheal intubation, disposable, and avoids cross infection of patients. The video laryngoscope blade body 1 is made of a transparent hard material to facilitate observation of the patient's throat state, and its surface is smooth without burrs, particles, etc., reducing the discomfort of the patient's throat.

[0029] Preferably, please refer to Figure 1 The video laryngoscope surface anesthesia device 100 further comprises a lens 3, which is arranged at the front end of the video laryngoscope body 1. The lens 3 has good transparency, which is conducive to the observation of the throat by the video laryngoscope and can better expand the field of vision. The passage nozzle 21 is close to the lens 3.

[0030] Please refer to Figure 1 Further, the passage nozzle 21 includes a side spray hole 211 and a front spray hole 212. The side spray hole 211 is provided on the side wall of the passage nozzle 21 for clearing the secretions on the lens 3; the front spray hole 212 is provided at the front end of the passage nozzle 21 for atomizing the anesthetic in the throat for local anesthesia.
