Embodiment Construction

[0015] An instrument for recording and stimulating muscle electrical signals generated by grinding teeth at night

[0016] Here we specifically introduce a kind of muscle electrical signal recording and stimulation instrument for recording teeth grinding at night. This instrument includes a measurement part and a feedback stimulation part. In the measurement part, the ICL7650 chopper operational amplifier is used as the preamplifier, and the magnification is set to 40 times. OP07 operational amplifier is used as main amplifier and 30Hz low-pass filter. The amplified and filtered signal enters the TLC2543 A / D conversion and enters the 89C51 single-chip microcomputer. In the single-chip microcomputer program, it is mainly to judge whether the myoelectric strength of the masticatory muscle exceeds 20uV and whether the period of the myoelectric signal is greater than 1 second. If the EMG signal satisfies the above two conditions at the same time, add 1 to the number of teeth gr...

Abstract

The electromechanical bruxism monitoring and treating equipment consists of a measuring and recording part and a feedback treating part. The measuring and recording part has surface electrodes capable of recording the myoelectric action of abnormal masseter during sleep. When the myoelectric strength exceeds certain amplitude and the myoelectric signal period becomes greater than certain value, the controller has its counter started and the counting result including the average strength is shown in the display. Then, the feedback treating part generates stimulating electric pulse to regulate the myoelectric action so as to reach the aim of treating bruxism. The electromechanical bruxism monitoring and treating equipment can monitor the teeth grinding time and strength as treating reference and treating bruxism by means of weak electric stimulation.

Description

Technical field: [0001] The invention belongs to the field of electronic technology, and in particular relates to a muscle electric signal recording and stimulating instrument for recording teeth grinding at night. Background technique: [0002] Night bruxism refers to repeated (period, more than 3 times, more than 0.5s each) or continuous (tonic, more than 2s) contraction (greater than the myoelectric contraction during strong occlusal) of the elevator muscle (masticator, temporalis, etc.). more than 20% of the graph value) are characteristic of orofacial movements that occur at night. Teeth bruxism manifests as grinding or tapping of teeth during sleep, sometimes accompanied by sounds. The clinical examination of long-term molars can find that the teeth have abnormal wear planes. Teeth bruxism patients may also have accompanying symptoms such as headache, facial muscle soreness and fatigue, temporomandibular joint symptoms, tooth sensitivity, and hypertrophy of the masse...
