Ventilation type laryngoscope for otorhinolaryngology department examination and use method of ventilation type laryngoscope

Abstract

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.

Description

technical field [0001] The invention relates to the technical field of laryngoscopes, in particular to a ventilating laryngoscope for otolaryngology inspection and a usage method thereof. Background technique [0002] Indirect laryngoscopy is the most commonly used method of laryngeal examination. The indirect laryngoscope is a circular plane mirror with a handle. The mirror surface and the mirror handle intersect at 120 degrees. The diameter of the mirror surface is different. An indirect laryngoscope with an appropriate size should be selected according to the condition of the subject's pharyngeal cavity. During the examination, the examinee is sitting on a chair, leaning forward, opening his mouth and sticking out his tongue, wrapping the front third of the tongue with clean gauze, pulling the tongue forward and downward, heating the indirect laryngoscope but not hot, and placing it in the mouth. For the pharynx, ask the subject to take a deep breath, pronounce the sound...

AI Technical Summary

Problems solved by technology

[0003] In the prior art, since the volume of the direct laryngoscope is generally large and needs to be placed in the throat of a person, it is often difficult for the patient to tolerate the direct laryngoscope, and the existing equipment is difficult to adapt to the different conditions of different patients. Ventilation requirements, and will affect the patient's breathing after placement, the existing equipment cannot assist the patient to ventilate, causing the patient to easily feel suffocated, causing great discomfort, and the existing equipment is usually difficult to perform well for different patients The adaptation of the equipment, the equipment can not be adjusted, or the adjustment is very cumbersome, and the disassembly and assembly are also very difficult, and the overall length of the equipment cannot be adjusted, which makes the whole equipment very inconvenient to use and cannot adapt to the examination needs of different patients , and it is usually difficult to adjust the overall length of the intermediate indirect laryngoscope in the prior art. When using it, it is usually inconvenient to pull out the laryngoscope in the device, and the existing device is usually not stable enough in structure, which affects the entire device. It is also prone to instability of the picture displayed on the touch screen due to unstable line connection, and it is not convenient when holding the device, and it is prone to slipping and other situations
