Description

Technical Field

[0001] The invention relates to the technical field of laryngoscopes, and in particular to a visual laryngoscope for assisting drug injection. Background Art

[0002] Because the larynx is located deep in the mouth and has a complex physiological structure, it cannot be directly viewed. Therefore, some special examination methods are needed to examine the larynx. The main clinical function of a laryngoscope is to insert it into the mouth to observe the throat. At the same time, it can open the larynx to facilitate surgical operations such as endotracheal intubation and drug injection.

[0003] In the prior art, a handheld laryngoscope is usually used. The doctor needs to hold the handle of the laryngoscope and adjust the posture of the laryngoscope so that it partially enters the patient's mouth to observe the throat and inject medicine. However, in the prior art, the handle part of the laryngoscope and the tongue depressor are an integrated structure. When using the laryngoscope, the tongue depressor and the camera need to be inserted into the patient's throat. However, sometimes observation and injection of medicine cannot be completed at one time, which leads to the need to frequently remove the tongue depressor and the camera from the patient's mouth, which reduces the patient's comfort.
