Abstract
Description

[0002] Dysphagia is a clinical symptom that is caused by damage to the mandible, lips, tongue, soft palate, throat, esophageal sphincter or esophagus, which makes it impossible to safely and effectively deliver food from the mouth to the stomach. Studies have found that electrical stimulation can make the stimulated muscles show a clear positive training effect. The normal swallowing reflex requires not only sufficient muscle strength, but also good sensory feedback and coordinated muscle operation. Electrical stimulation therapy can effectively enhance muscle strength, improve the flexibility and coordination of pharyngeal muscles, thereby increasing sensory integration input, effectively promoting the recovery of swallowing function, and improving dysphagia.
[0003] The existing technology mostly uses a swallowing disorder therapeutic device to complete the above-mentioned electrical stimulation treatment process, but the therapeutic device is expensive and is not suitable for large-scale teaching use. In the clinical treatment process, the therapeutic device mostly uses an electrode patch to stick on the patient's mandible or neck to apply electrical stimulation to the nerves there. This method is difficult to directly stimulate the corresponding part in the oral cavity, the electrical stimulation intensity is weak, and positioning is prone to errors, resulting in poor treatment effects.
