Description

Adjustable oral support

The present invention relates to a medical aid device, and more particularly to an oral support frame for propping up the upper and lower jaw portions to facilitate insertion of a medical device into the throat of a patient.

In clinical practice, when a disease occurs in the human body, it is necessary to use a medical device such as a laryngoscope, a gastroscope or a cannula to reach the affected part and reach the affected part. When testing and treating, it often takes a certain time, and the medical staff needs to open the mouth during this operation. Cooperate, in order to enable medical personnel to complete a complete inspection or treatment work, and medical personnel often have a clear vision for the operation, and the patient needs to open the mouth as much as possible. As a result, the patient is prone to fatigue due to prolonged mouth opening, and most patients cannot adhere to it and need to be interrupted. Time to rest and spit out the saliva in the mouth, causing the patient's visit time to prolong, and delaying the patient waiting for the visit, of course, also increasing the time for the medical staff to check and treat the patient, especially for the use of intubation or gastroscope to reach the throat and stomach In the case of examination or treatment, such patients must first perform anesthesia in order to carry out subsequent examinations and medical treatments.
