Mouth gag with accurate training

Abstract

The invention relates to an oral cavity mouth gag, particularly to a mouth gag with accurate training. The mouth gag comprises an air bag matching a dental arch in shape, an air guide pipe is connected to the air bag, an external air source is inflated into the air bag arranged between an upper tooth and a lower tooth through the air guide pipe to expand the air bag so that an oral cavity can be opened, and a measuring device capable of measuring the expansion height of the air bag is arranged on the air bag. The expansion height of the air bag is detected through the measuring device, a usercan know the expansion height of the air bag conveniently, so that the mouth opening degree of the oral cavity is monitored in real time; ordered and accurate training can be conducted by controllingthe different expansion heights of the air bag; the purpose of rapid and effective mouth opening training is achieved; and the mouth gag is easy to operate, accurate in control and convenient to use.

Description

technical field [0001] The invention relates to mouth opening, in particular to a mouth opening device for precise training. Background technique [0002] Clinically, patients with oropharyngeal radiotherapy need to perform mouth opening training, otherwise, it is easy to cause oropharyngeal muscle fibrosis after radiotherapy, resulting in difficulty in opening the mouth. At present, most of the methods used are to contain a cork in the mouth during radiotherapy, and passively open the mouth to prevent oropharyngeal muscle fibrosis; however, containing a cork is more painful, and if the cork is accidentally left in the patient's mouth, it will cause aspiration, which is serious. Occasionally, it may block the patient's airway and cause the patient to suffocate to death. In the prior art, an inflatable oral mouth opener has also appeared. Although this type of mouth opener overcomes the disadvantages of using a cork to open the mouth, the user does not know the degree of inf...

[0002] Clinically, patients with oropharyngeal radiotherapy need to perform mouth opening training, otherwise it is easy to cause oropharyngeal muscle fibrosis after radiotherapy, resulting in difficulty in opening the mouth

At present, most of the methods used are to contain a cork in the mouth during radiotherapy, and passively open the mouth to prevent oropharyngeal muscle fibrosis; however, containing a cork is more painful, and if the cork is accidentally left in the patient's mouth, it will cause aspiration, which is serious. May block the patient's airway and cause the patient to suffocate to death

In the prior art, an inflatable oral mouth opener has also appeared. Although this type of mouth opener overcomes the disadvantages of using a cork to open the mouth, the user is not clear about the degree of inflation of the airbag, and it is difficult to achieve the purpose of precise training.
