Description

Laryngoscope with adjustable angle

Technical Field

The utility model relates to a laryngoscope, in particular to an angle-adjustable laryngoscope.

Background

At present, the medical laryngoscope mainly comprises a common laryngoscope and a visual laryngoscope, and the laryngoscope blade of the common laryngoscope is divided into a large model, a medium model, a small model and the like, so that the medical laryngoscope is convenient to be suitable for patients with different body types. But also comprises a Miller straight laryngoscope lens and a Macintosh bent laryngoscope lens, which are convenient for peeping the glottis of patients under different angles of mouth and throat. However, direct exposure of the glottis is still difficult at present due to anatomical variations of different patient individuals and the influence of disease factors such as ankylosing spondylitis, small mandible, obesity and the like. In recent years, the visual laryngoscope is popular in clinic, and has the advantages of improving the visual field of the common laryngoscope, reducing difficult intubation, and being widely applied because the visual field is clear and the glottis do not need to be peeped at a short distance.

However, the model of the lens of the visual laryngoscope is relatively fixed except the display screen, the angle of the camera is fixed, and the visual laryngoscope has great limitation in clinical application, is still a great challenge for medical staff when encountering the situations of high sound door, stiff neck, and the like, and can even evolve into an emergency airway after repeated intubation, thereby endangering the life of patients. The visual soft mirror in the current market is tubular visual field, and has no support of tongue depressor in front, and has large observation difficulty and poor accessibility, although the visual soft mirror can adjust the visual field angle.
