Neurogenic dysphagia is often accompanied by weakness in muscle contractions associated with swallowing. Neuromuscular electro-thorn is an important method for treating dysphagia. The current neuromuscular electrical stimulator for treating dysphagia mainly consists of an electrical stimulator, a current output lead and a stimulating electrode. During treatment, the stimulating electrode is first required to be in close contact with specific deglutition muscle group, then specific current generated by the electric stimulator is transmitted to the stimulating electrode through the current output wire, and the deglutition muscle group contacted with the electrode is directly stimulated, so that the purpose of improving the corresponding muscle function is achieved. Therefore, the stimulation electrode is a key to applying the power generated by the electric stimulator to the target muscle group.
