Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of medical devices, and in particular to an auxiliary distraction device for awake intubation of ankylosing spondylitis patients. Background Art
[0002] In clinical anesthesia intubation, especially for tracheal intubation of patients with difficult airway, an advanced tool for difficult airway treatment, the visual intubation soft mirror, is often needed. Especially for patients with ankylosing spondylitis, the problem of difficult airway is particularly severe, and the visual intubation soft mirror is often used for awake intubation to avoid the occurrence of emergency difficult airway and affect the patient's life safety. Now many patients have abnormal body position, limited mouth opening, stiff joints, and forward head. Other tools cannot be placed in the mouth clinically. The use of a visual intubation soft mirror is the best choice. However, when using a visual intubation soft mirror for patients with ankylosing spondylitis, it is often difficult to distinguish the specific anatomical structure, because the epiglottis of ankylosing spondylitis patients collapses and covers the glottis, and the visual intubation soft mirror is often blocked by the depressed epiglottis, resulting in unsuccessful intubation. Because the visual intubation soft mirror has its own operational characteristics as an advanced airway treatment tool: the visual intubation soft mirror requires a certain space to have a field of view to distinguish the anatomical structure.
[0003] For example, the utility model with the announcement number CN217988117U discloses an improved oropharyngeal airway for assisting visual soft-scope endotracheal intubation, including a wing, a tooth pad and a pharyngeal curve, wherein the wing is connected to the tooth pad, and the tooth pad is connected to the pharyngeal curve, and the wing, the tooth pad and the pharyngeal curve all have openings, and the openings are connected to each other to form a long gap, and the wing, the tooth pad and the pharyngeal curve are integrally formed and connected in the middle. The utility model can effectively assist the insertion of the visual intubation soft-scope, and can quickly find the epiglottis and glottis in the case of hypertrophy or excessive posterior fall of the patient's tongue, significantly shorten the endotracheal intubation time, and reduce the difficulty of operation. However, it cannot solve the problem that when the patient is in the awake intubation state, the epiglottis collapses and covers the glottis, and the visual intubation soft-scope will be blocked by the depressed epiglottis, resulting in unsuccessful intubation.
[0004] In view of this, the inventor conducted in-depth research on this demand, and thus the present case was produced. Utility Model Content
