Electronic laryngoscope convenient for observation

Abstract

The invention discloses an electronic laryngoscope convenient for observation. The electronic laryngoscope comprises a handle, a display, a laryngoscope blade and a trachea cannula; the display is movably connected to the top of the handle; a connecting pile is arranged at the bottom of the handle; one end of the trachea cannula is fixedly connected to the end of the connecting pile; an LED lightsource and a camera are arranged at the other end of the trachea cannula; the laryngoscope blade is arranged on the trachea cannula; one end of the laryngoscope blade is connected with the connectingpile in an inserting way; and a tongue fixing device is arranged on one side, inclined to the connecting pile, of the laryngoscope blade. When the novel electronic laryngoscope disclosed by the invention is used for detecting a larynx of a patient, a tongue of the patient can be further fixed while the laryngoscope blade extends for pressing, so that a shooting effect is prevented from being influenced by a process that the tongue is curled inwards or moves irregularly due to pharyngeal reflection of the patient. The operation process is simple, and shooting stability of working parts can be obviously improved.

Description

technical field [0001] The invention relates to the technical field of medical appliances, in particular to an electronic laryngoscope convenient for observation. Background technique [0002] The physiological structure of the larynx of the human body is very complicated, and it is impossible to directly observe the situation inside. When a disease occurs, it is necessary to use some special medical equipment to observe it, so as to determine the disease. Laryngoscope is a kind of medical equipment specially designed for laryngeal examination. There are many types of laryngoscope. Electronic laryngoscope has the advantages of small inspection stimulation, no pain, high-definition inspection screen, convenient and easy operation, and short operation time. characteristics, and become the most acceptable examination method for patients. When using a traditional electronic laryngoscope to examine a patient, first use the curved laryngoscope blade to press the patient's tongue ...

AI Technical Summary

Problems solved by technology

When using a traditional electronic laryngoscope to examine a patient, first use the curved laryngoscope blade to press the patient's tongue to the lower jaw to open the larynx, and then use the built-in high-definition camera and LED light source for observation. However, for Some subjects with severe gag reflex, because the tongue is only subjected to a lateral pressure and is not fixed, will still curl up inward due to the nausea reflex, blocking the throat, hindering the inspection and affecting the shooting of the camera Effect
