Self-feedback type masseter muscle relieving instrument used for treating sleep bruxism and control method thereof

Abstract

The invention provides a self-feedback type masseter muscle relieving instrument used for treating sleep bruxism and a control method thereof. The relieving instrument comprises functional parts symmetrically arranged on the two sides and a connecting part for connecting the two functional parts. Each functional part comprises a shell. A miniature pressure sensor, a miniature messaging device and a PLC are arranged in each shell. Each miniature pressure sensor is used for collecting pressure signals caused by face structure changes of vicinity points of ascending limb masseter muscle of the mandibula of the cheek. Each PLC is used for receiving the pressure signals and controlling the corresponding miniature messaging device to start the messaging procedure according to the pressure signals. Each miniature messaging device carries out messaging for relieving the masseter muscle according to the messaging procedure. By means of the automatic control device, the function is started when abnormal muscle motion begins, the relieving instrument messages and relieves the muscle moving abnormally, then the abnormal muscle motion is stopped, and by means of the method, the purpose of truly treating sleep bruxism is achieved.

Description

【Technical field】 [0001] The invention relates to the field of medical devices, in particular to a self-feeding masseter muscle soothing instrument for treating bruxism and a control method thereof. 【Background technique】 [0002] The main manifestation of bruxism is that the upper and lower teeth clench and slide and rub after a deep sleep at night. The occlusal force is so large that it cannot be achieved under normal circumstances. The upper and lower teeth make a unique grinding sound when rubbing and sliding, which will cause serious wear to the natural teeth. . Because the masseter muscle is too strong and too strong, people with bruxism will have facial muscle soreness and fatigue in the morning. At the same time, it will also cause damage and destruction to the temporomandibular joint. Therefore, the harm of night bruxism is obvious. However, the cause of bruxism has not been clarified so far. Most tend to think that it is the result of involuntary discharge of bra...

AI Technical Summary

Problems solved by technology

However, the defect of this method is obvious. Although the wear and tear on the teeth is reduced, the muscle soreness and fatigue caused by excessive force cannot be relieved, and the process of grinding teeth at night still exists.

What's more serious is that some patients change the contact relationship between teeth because of wearing dental pads, which will increase the amount of nighttime exercise of the masseter muscles and lead to aggravation of facial fatigue

And the technique and the method of terminating nighttime bruxism by inhibiting abnormal muscle movement have never been reported
