Description
Technical Field
[0001] The invention relates to the technical field of human electromyographic signal detection electrodes, and in particular to a mask-type masticatory muscle bilateral electromyographic signal detection electrode array. Background Art
[0002] Currently, various medical electronic devices have been widely used in the field of diagnosis and treatment, especially in the detection and analysis of nerve and muscle diseases and the reconstruction of motor function of paralyzed limbs. The electromyographic signal detection electrode is a kind of medical electronic device, which is equivalent to the connecting bridge between the organism and the electronic system. At present, the single-chip electromyographic signal detection electrode is widely used in the diagnosis of nerve and muscle diseases in the electromyography room of the hospital.
[0003] As a supporting device of the "electromyoelectric bridge limb movement instrument" that has obtained the medical device registration inspection in China, completed clinical trials, and obtained the EU medical device CE certificate internationally, the human body electromyographic signal detection electrode is used for limb movement function rehabilitation training of hemiplegic and paraplegic patients. The typical application is to obtain the electromyographic signal of the healthy arm of the hemiplegic patient during the movement, amplify and regenerate it, and then stimulate the affected arm to make synchronous and harmonious movements, or obtain the electromyographic signal of the upper limb of the paraplegic patient during the movement, amplify and regenerate it, and then stimulate the lower limb to make synchronous and harmonious movements.
[0004] As for patients with complete paralysis, ALS and disabled elderly people, since their upper and lower limbs cannot move, the only option currently is to obtain electromyographic signals from healthy people's limbs, amplify and process them, and then stimulate the patient's limbs to make synchronous and harmonious movements. This requires the patient's family or other caregivers to invest a lot of time and energy, and the patient's psychological trauma of "inferiority and incompetence" cannot be comforted. In response to this situation, human electromyographic signal detection electrodes can be used to obtain the electromyographic signals of healthy people's chewing muscles and control the movements of the upper and lower limbs through the "electromyo bridge limb movement instrument". However, in actual applications, it is found that it is difficult to stably obtain electromyographic signals by firmly attaching electrodes to the chewing muscles in a vertical state. At the same time, considering the patient's and his family's expectations that the patient himself can control both upper or lower limbs through chewing movements, the patent application of the present invention proposes a mask-type masticatory muscle bilateral electromyographic signal detection electrode array. Summary of the invention
[0005] The purpose of the present invention is to provide a mask-type bilateral electromyographic signal detection electrode array for masticatory muscles, so that the electromyographic signal detection electrode array can be firmly attached to the masticatory muscles in a vertical state, ensuring stable acquisition of electromyographic signals, and reliably detecting the electromyographic signals during chewing from the masticatory muscles on both sides of patients with complete paralysis, patients with ALS or disabled elderly people, and then through the successfully developed dual-channel "electromyoelectric bridge limb movement instrument" to achieve the purpose of rehabilitation reconstruction or at least prevent muscle atrophy. In addition, this type of electrode array can be used for people with special needs to achieve other control purposes through chewing actions and signal processing devices.
[0006] To achieve the above-mentioned purpose, the present invention provides a mask-type bilateral electromyographic signal detection electrode array for chewing muscles, comprising a mask body, wherein tensioning strips are provided on both sides of the mask body, and two symmetrically arranged electromyographic signal detection electrode arrays are provided on the mask body, and the electromyographic signal detection electrode arrays are arranged corresponding to the chewing muscle parts.
[0007] Preferably, an integrated three-electrode dedicated to electromyographic signal detection is provided in the middle of the electromyographic signal detection electrode array, and the integrated three-electrode dedicated to electromyographic signal detection includes three electrodes arranged up and down, the two electrodes at the upper and lower ends are differential detection electrode pairs, and the middle electrode is a reference electrode, and a rectangular window corresponding to the integrated three-electrode dedicated to electromyographic signal detection is provided on the mask body.
[0008] Preferably, a convex metal connector is provided at the upper and lower ends of the electromyographic signal detection electrode array, respectively, and a concave metal connector corresponding to the convex metal connector is provided on one side of the mask body close to the human skin, and the convex metal connector and the concave metal connector are respectively a female buckle and a female buckle for adaptive connection.
[0009] Preferably, a conductive cloth strip arranged around the rectangular window is adhered to a side surface of the mask body close to human skin, and an anti-counterfeiting and anti-interference electrode is connected to the conductive cloth strip near the edge of the ear.
[0010] Preferably, the mask body is made of a flexible cloth.
[0011] Preferably, the tensioning strip of cloth located on the left side of the mask body is provided with a Velcro velvet surface, and the tensioning strip of cloth located on the right side of the mask body is provided with a Velcro hook surface.
[0012] Preferably, the mask body is provided with a first opening and a second opening corresponding to the nose and the mouth, respectively.

[0014] (1) The present invention is suitable for detecting the electromyographic signals of chewing movements from the bilateral masticatory muscles of patients with amyotrophic lateral sclerosis (ALS), paraplegic patients and disabled elderly people, and using the self-consciousness expressed by the chewing movements to control the movements of the bilateral upper or lower limbs through the "EMG bridge limb movement instrument" to achieve limb motor function rehabilitation training or prevent muscle atrophy. In particular, it has a unique application effect on ALS patients, because most ALS patients may still chew in the later stages of the disease. In addition, this type of electrode array can be used for people with special needs to achieve control purposes through chewing movements and signal processing devices;
[0015] (2) Two groups of myoelectric signal detection electrode arrays and anti-counterfeiting and anti-interference electrodes on the outer side of the mouth corners are combined with the tensioning cloth belt into a whole through a specially shaped strip of cloth, which can be manufactured in a standardized manner;
