Inflatable mouth opening trainer

Abstract

The invention discloses an inflatable mouth opening trainer which comprises a mounting base, an air bag, an upper tooth moving plate, a lower tooth moving plate, a tooth fixing mechanism, a first switch, a first spring, a driving rod, a locking mechanism, a limiting mechanism, an inflation pump and a battery.According to the inflatable mouth opening trainer, firstly, the tooth fixing mechanism is used, so that the inflatable mouth opening training device is fixed with teeth of a patient; meanwhile, stress points are dispersed, a limiting mechanism is controlled through an adjusting mechanism, then the limiting mechanism expands an air bag to push the distance between an upper tooth moving plate and a lower tooth moving plate to restrain, and then the mouth of the patient is in a passive reciprocating opening and closing training state through rebounding of a first spring; in this way, it is ensured that the amplitude of mouth opening training of the patient is consistent each time, and the mouth opening degree can be adjusted. By means of the device, the mouth opening training effect of the patient is improved, the postoperative rehabilitation training progress of the patient is ensured, and meanwhile stress points are dispersed, so that tooth damage is prevented.

Description

technical field [0001] The invention relates to the technical field of medical auxiliary equipment, in particular to an inflatable mouth opening trainer. Background technique [0002] Patients with temporomandibular joint dysfunction, mandibular condyle fracture, simple intermaxillary ligation, temporomandibular joint surgery, maxillofacial infection or maxillofacial long-term radiotherapy may cause different degrees of limited mouth opening. The natural opening and closing of the mouth cannot reach the state before radiotherapy. In order to restore the opening function of the patient's mouth, the patient needs to use equipment for mouth opening training. [0003] At present, the traditional mouth gag is made of hard plastic and stainless steel, which will damage the tooth enamel when the force is applied, and the force point of the traditional gag training is concentrated, which is easy to cause damage to the stressed teeth. At the same time, the traditional gag training me...

Problems solved by technology

[0003] At present, the traditional mouth gag is made of hard plastic and stainless steel, which will damage the tooth enamel when the force is applied, and the force point of the traditional gag training is concentrated, which is easy to cause damage to the stressed teeth. At the same time, the traditional gag training method cannot ensure that patients The range of mouth opening is the same every time, and the range of mouth opening cannot be adjusted at the same time, which reduces the training effect of patients and misses the best training time. In view of the above defects, it is necessary to design an inflatable mouth opening trainer
