Laryngoscope with expansible tongue depressor

Technical Field

The utility model relates to the technical field of medical equipment, concretely relates to laryngoscope with expansible tongue depressor.

Background

In clinical medicine, when general anesthesia or critical case emergency treatment is performed on a patient, tracheal intubation is an important key step, and the success or failure of tracheal intubation directly influences the implementation of anesthesia and surgery and the success rate of critical patient rescue. At present, the most common tracheal intubation method in China is to lift a laryngoscope to expose a glottis under the assistance of a laryngoscope lens and insert a tracheal catheter into a trachea through the glottis under direct vision. However, the throat structure of the human body is complex, and the difference of tissue structures of different patients is large, such as the tongue root is large, the epiglottis is long and thin, and the lower jaw is small, so that the risk of inserting the tube due to insufficient glottic exposure is easy to occur.

The traditional laryngoscope method is that a laryngoscope lens is placed into the oral cavity along the tongue body until the epiglottis reaches, then the epiglottis is lifted by using the laryngoscope lens to expose the glottis, at the moment, medical personnel insert the tracheal catheter through the glottis, the intubation technique is observed by naked eyes or a front camera, the sight line is influenced by the incisal margin, the bending of the oral cavity respiratory tract, the shielding of the epiglottis and the curling of the tongue body, the parallax and the blind area are easy to exist, and the exposure of the glottis is unclear; therefore, the process needs operators to complete the process by experience, and in addition, the phenomenon of difficult intubation is easily caused due to individual difference of patients, and the injury such as bleeding, edema or tissue wound is caused to the inner walls of the tissues of the oropharynx part and the laryngopharynx part, so that the rescue time of the patients is delayed.

Based on the above problems, in the process of placing a trachea cannula, the technical problems to be solved by the technical personnel in the field are that the tongue body is fully pressed, the tongue surface is stretched, the epiglottis is lifted, and the glottis is exposed.
