Device for mouth opening exercise of patients after radiotherapy

Abstract

The invention provides a device for mouth opening exercise of patients after radiotherapy. The device comprises an upper dental pad, a lower dental pad and a support for fixing the dental pads, the dental pads comprise the upper dental pad and the lower dental pad, the support is of an up-down telescopic structure, and a height measuring device is also fixed on the support. The support is a rhombic movable frame, and a jaw fixing plate is further arranged below the rhombic movable frame. The used upper dental pad and lower dental pad are convenient to clean, low in bacterial residue amount, and more sanitary than existing corks used clinically; the height between the upper dental pad and the lower dental pad can be adjusted at will, and a user can adjust the mouth opening limit according to personal conditions; the height measuring device is arranged, so that a user, medical staff and accompanying staff can visually see the mouth opening height, and mouth opening exercise is standardized; and the graduated scale of the height measuring device can measure the height between the upper tooth and the lower tooth of the user so as to determine the mouth opening height.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a device for mouth opening exercises for patients after radiotherapy. Background technique [0002] Nasopharyngeal carcinoma is a common malignant tumor of the head and neck. At present, the conventional method for the treatment of nasopharyngeal carcinoma is intraoral radiotherapy. Although the radiotherapy technology is becoming more and more mature, the incidence of many complications has been reduced, but after oral radiotherapy, the muscles of mastication and mandible When the joints are affected by the rays, fibrosis will occur, which will cause difficulty in opening the mouth. Difficulty in opening mouth is one of the common complications of nasopharyngeal carcinoma patients after radiotherapy. Exercise the masticatory muscles and jaw joints to prevent their function degeneration. [0003] Existing routine clinical mouth opening exercise devices are usually a common cork, ...

AI Technical Summary

Problems solved by technology

First, the general specifications of cork are fixed. For patients with serious difficulty in opening their mouth, it is difficult to put the cork into the patient's mouth for mouth opening support, and the patient cannot adjust the degree of mouth opening exercise; , After exercising with cork stoppers, the cork stoppers are not easy to clean. After cleaning, the surface of the cork stoppers often contains certain bacteria, which is not hygienic and safe.

[0004] Some existing special-purpose mouth-opening exercise devices mainly have three deficiencies. First, when doing mouth-opening exercises, it is necessary to support the opening of the mouth to a certain extent and stay for 10-20 seconds. For fixed support devices, the user often needs to grasp and control the degree of mouth opening. When exercising for many times for a long time, the user will feel fatigued, the grip strength will decrease, and the opening height will often not meet the requirements, which will affect the quality of exercise; second, Some devices are not equipped with a device for measuring the height of the oral cavity or the installed measuring device is intelligently seen by the medical staff or accompanying personnel. The user cannot observe the height of the mouth opening. When the user only exercises personally, the user cannot determine whether the degree of mouth opening is Comply with the regulations; Third, some special mouth opening training devices have multiple fixed specifications. For example, the mouth opening training devices only have the specified support heights of 1.0cm, 1.5cm, 2.0cm, 2.5cm, 3.0cm and 3.5cm. When choosing a certain mouth opening height to support the mouth, it is not flexible enough to use, nor can it be adjusted according to different patients or different degrees of mouth opening exercise
