Description

Oral rehabilitation training device with digital display

Technical Field

The utility model relates to a recovered medical instrument, concretely relates to interlock flesh exerciser.

Background

Nasopharyngeal carcinoma is one of the most common malignant tumors in China, and radiation therapy is mainly used. But the mouth opening difficulty is one of the common complications of radiotherapy, the incidence rate can be as high as 58.5%, the incidence rate of severe mouth opening difficulty is 7.1%, especially after DT40Gy/4W, the reduction of incisor space begins to appear, and the dose is increased and aggravated as the radiotherapy time is prolonged. The bilateral temporomandibular joint is exposed to multiple doses of radiation, resulting in joint hardening and chronic radiation fibrosis of the masticatory muscles, which leads to impaired joint movement and dysfunction of the masticatory muscles. Research shows that the mouth opening exercise or proper forced mouth opening exercise and occlusion training can promote local blood circulation, increase muscle tension, prevent muscle fibrosis and joint stiffness, promote the functional recovery of masticatory muscles and maximally recover the range of motion of upper and lower jaws and occlusion function.

As shown in the attached drawing of the specification of the patent, when the exerciser is used, the elastic part 4 is arranged, the upper and lower tooth trays 3 are closed and placed in the mouth of a patient, the elastic part 4 is in a compressed state at the moment, the elastic force generated by the elastic deformation of the elastic part 4 helps the patient to perform passive mouth opening exercise and active occlusion exercise, the patient unscrews the second locking part 7, then slides the tooth tray 3 connected with the lower moving rod 2-2 upwards, and then fixes the ulnar tray 3, so that the distance between the upper and lower ulnar trays 3 is different from 0.7cm to 1.2cm, and the patient can select the mouth exerciser according to the self condition.

This prior application patent when adjusting the interlock stroke, needs a plurality of knobs of adjustment when the user bites, and the operation is very inconvenient, simultaneously because need bite the exerciser when adjusting the interlock stroke, leads to the scale to be sheltered from by last branch, and the user can not observe the interlock stroke that shows on the scale directly perceivedly when using alone.

In order to solve the above technical problems, the applicant filed a patent application with application number ZL201921460194.8 on 9/4/2019, which provides a rehabilitation exerciser for oral cavity expansion and bite training, but the applicant found that the rehabilitation exerciser has the following technical problems after receiving feedback of use of a patient.

The rehabilitation exerciser in the prior art can not display the occlusal force of a patient in real time, can only indirectly judge the maximum occlusal force which can be achieved by the patient through an occlusal stroke, and the size of the occlusal force cannot be visually displayed through data.

In addition, the masticatory muscles include the masseter muscle, the temporalis muscle, the lateral pterygoid muscle and the internal pterygoid muscle, and the rehabilitation exerciser is mainly used for exercising the masseter muscle and the temporalis muscle, and the bilateral temporalis-mandibular joint is irradiated by more radiation with the prolongation of the radiation treatment time and the increase of the radiation dose, so that the masseter muscle is more serious relative to the fibrosis of the temporalis muscle. In the process of using the rehabilitation exerciser to exercise, the masseter and the temporalis muscle are required to be matched with each other, because the damage degree of the masseter and the temporalis muscle is different, and the force sent by a patient when the patient bites and lifts the jaw is difficult to control freely, so when the patient uses the rehabilitation exerciser for the first time, the patient is often too large to adjust when matching the corresponding expansion stroke because the biting force of the masseter of the patient is not known, and the patient in the bite rehabilitation training is damaged.
