Technical Field

The utility model relates to the technical field of medical instruments, in particular to a surface anesthesia device matched with a video laryngoscope for use.

Background

The laryngoscope can be used as a tool for exposing the glottis when the trachea is intubated in the general anesthesia induction and on-site cardiopulmonary resuscitation process, and in the process, the laryngoscope presses the oral epiglottis of the human body so as to carry out the trachea intubation; laryngoscopes are sometimes needed in the process of laryngeal diagnosis and treatment; the function of the laryngoscope requires that the laryngoscope is provided with a display device so as to clearly understand the laryngeal condition of a patient when corresponding medical activities are carried out; when the laryngoscope is used, the laryngoscope needs to enter from the oral cavity and reaches the glottis position through the deep part of the pharynx, and the anesthetic laryngoscope can generate stress reactions such as vomit or swallowing reflex and the like when in use, thereby influencing the laryngoscopy and even possibly bringing other adverse consequences. Therefore, when using a laryngoscope, a site such as the oral cavity, the glottis, and the main bronchus is required to be subjected to surface anesthesia.

At present, for equipment for laryngeal anesthesia, a laryngeal sprayer is usually adopted for performing surface anesthesia on a glottis, while the traditional laryngeal sprayer mostly adopts a mode of spraying anesthetic liquid medicine by manual extrusion or a high-pressure pump to realize atomization of the liquid medicine, but the mode of manual extrusion cannot ensure that the liquid medicine is continuously sprayed out, and the atomization effect is not ideal; the high-pressure pump ejection method has a problem of low atomization efficiency, and may eject liquid that has not been atomized together, so that the local anesthesia amount is too large or too small, thereby affecting the anesthesia effect.
