Description

Technical Field

[0001] The invention relates to the field of medical devices, and in particular to a device for mouth opening exercise for patients after radiotherapy. Background Art

[0002] Nasopharyngeal carcinoma is a common malignant tumor of the head and neck. The conventional method for treating nasopharyngeal carcinoma is oral radiotherapy. Although radiotherapy technology is becoming more and more mature and has reduced the incidence of many complications, after oral radiotherapy, the masticatory muscles and mandibular joints are affected by radiation and fibrosis will occur, causing difficulty in opening the mouth. Difficulty in opening the mouth is one of the common complications of nasopharyngeal carcinoma patients after radiotherapy. The incidence rate is extremely high. In severe cases, it can cause patients to have difficulty eating due to clenched teeth, affecting their quality of life. Therefore, after radiotherapy, doctors often advise patients to perform mouth opening function exercises to exercise the masticatory muscles and mandibular joints to prevent their functional degeneration.

[0003] The existing conventional clinical mouth opening exercise device is usually a common cork plug, which is placed in the mouth to support the mouth opening. First, the specifications of the cork plug are generally fixed. For patients with severe mouth opening difficulty, it is difficult to put the cork plug into the patient's mouth to support the mouth opening when using the cork plug for exercise, and the patient cannot adjust the degree of mouth opening exercise; second, after using the cork plug for exercise, the cork plug is not easy to clean, and the surface of the cork plug after cleaning often contains certain bacteria, which is not hygienic and safe.

[0004] Some existing special mouth opening exercise devices have three main shortcomings. First, when doing mouth opening exercise, it is necessary to support the oral cavity to stay open at a certain degree for 10-20 seconds. The existing special mouth opening exercise devices are not provided with a fixed support device, and the user is often required to grasp and control the degree of mouth opening. When exercising for a long time and multiple times, the user will feel tired, the gripping force will decrease, and the mouth opening height will often fail to meet the regulations, affecting the quality of exercise; second, some devices are not provided with a device for measuring the height of the oral cavity, or the measuring device provided can only be seen by medical staff or accompanying personnel, and the user cannot observe the height of the mouth opening. When the user exercises alone, the user cannot determine whether the degree of mouth opening meets the regulations; third, some special mouth opening exercise devices are provided with multiple fixed specifications. For example, the mouth opening training device only has 1.0 cm, 1.5 cm, 2.0 cm, 2.5 cm, 3.0 cm and 3.5 cm such specified support heights. When using it, a certain mouth opening height is selected to support the oral cavity. It is not flexible enough to use, and it cannot be adjusted according to different patients or different degrees of mouth opening exercise. Summary of the invention
