Description

A mandibular fixation device for opening the airway of anesthetized patients

Technical Field

The utility model relates to the technical field of medical instruments, in particular to a mandibular fixing device used for opening the airway of an anesthetized patient.

Background Art

Anesthesiology is an important department in modern western medicine. From a medical point of view, anesthesia means to temporarily make the patient lose sensation in whole or in part through drugs or other methods to achieve the purpose of painlessness and provide conditions for surgical treatment or other medical examinations and treatments. When performing surgery on a patient, anesthesia is often used to make the patient lose sensation in whole or in part to facilitate the operation.

When the anesthesiologist injects general anesthetics intravenously or inhales anesthetic gases into the patient, the patient loses consciousness 3 to 5 minutes after the drug is administered, and goes from being awake to sleeping. Under general anesthesia, since the anesthetized patient is unconscious and the muscles of the whole body are relaxed, the tongue is prone to fall back, blocking the pharynx, causing airway obstruction, and leading to hypoxia in the anesthetized patient. Therefore, the anesthesiologist must tilt the anesthetized patient's head back and use both hands to lift the anesthetized patient's lower jaw upward to open the airway, keep the airway open, and avoid hypoxia. For patients undergoing non-intubated general anesthesia, the anesthesiologist must use both hands to hold up the anesthetized patient's lower jaw to open the airway throughout or most of the time, and cannot use both hands for other medical procedures, which limits their movements. Therefore, we propose a lower jaw fixation device for opening the airway of anesthetized patients to solve the above-mentioned problems.
