The invention belongs to the technical field of
laryngoscopes, particularly relates to a ventilation type laryngoscope for
otorhinolaryngology department examination and use method of ventilation type laryngoscope, and provides the following scheme for solving the problem of laryngoscope examination: the ventilation type laryngoscope for examination in the otolaryngology department comprises a lens main body, a touch screen and a fixed seat, wherein the ejector block is additionally arranged on the side wall of the
laryngoscope blade, the vent hole is formed in the side wall of the ejector block, and the second spring is additionally arranged on the side wall of the
laryngoscope blade and connected with the ejector block, so that the ejector block can be ejected forwards; the ejector block is ejected forwards during laryngoscope examination, then the vent hole can be communicated with the two side walls of the
laryngoscope blade, and ventilation can be conveniently carried out on the inside of the
throat of a patient; thus, the suffocation feeling brought to a patient when the
throat pipe is inserted is reduced, and the discomfort of the patient is reduced; when the pull
rope is pulled, the top block can be pulled towards the inner side, so that the position of the vent hole moves to the inner side of the laryngoscope blade, and the ventilation process is
cut off; in addition, the end face of the laryngoscope blade is kept flat, and the laryngoscope blade can be conveniently pulled out after operation is completed.
