Laryngoscope

Abstract

Disclosed is a laryngoscope which is capable of safely and reliably lifting the epiglottis to easily view the entrance to the trachea directly. Specifically disclosed is a laryngoscope in which the base end section of a blade for being inserted from patient's mouth to lift the epiglottis in order to visually identify the entrance to the trachea is consecutively installed at the end of a handle which can be gripped, and which is configured in such a manner that a first electrode is provided to the base end section of the blade and a second electrode can be adhered to the skin surface adjacent to the epiglottis, and that a low-frequency current is energized between the first electrode and the second electrode.

Description

technical field [0001] The present invention relates to a laryngoscope, in particular to a laryngoscope used in the fields of anesthesia, first aid, intensive treatment, etc., for visually identifying the entrance of the trachea by raising the epiglottis. Background technique [0002] In the fields of anesthesia, first aid, intensive care, etc., a catheter is usually inserted into the trachea from the mouth to ensure the passage of oxygen necessary for breathing, that is, the airway (airway assurance). [0003] When securing the airway, a procedure called laryngeal opening is performed in order to visually recognize the entrance of the trachea before inserting the catheter. That is, there is a lid portion called the epiglottis at the entrance of the trachea, and the epiglottis prevents food from entering the trachea. When securing the airway, if the epiglottis is not provoked, the visual field may be obstructed so that the entrance of the trachea cannot be visually recogniz...

AI Technical Summary

Problems solved by technology

When securing the airway, if the epiglottis is not provoked, the field of view may sometimes be obstructed so that the entrance of the trachea cannot be visually recognized
