l Evaluation mechanism of swallowing nerve and muscle electrical stimulators

When the human nervous muscles are stimulated by electricity, there are different stimulation thresholds for triangular pulse waves with slow intensity changes and square pulse waves with fast intensity changes, and the degree of difference is closely related to the degree of muscle denervation. Based on this characteristic, triangle wave and square wave currents are used to stimulate the patient's swallowing muscles, and their threshold values are measured. The quotient of the threshold values is called the fitness coefficient α. The degree of swallowing disorder is determined based on the magnitude of the α value, including normal, mild, and severe, in order to determine the treatment and training plan.

l Swallowing nerve and muscle electrical stimulatorThe mechanism of treatment and training

Placing electrodes in the neck of the patient's throat, specific therapeutic currents are used to electrically stimulate swallowing related nerves such as the recurrent laryngeal nerve, sublingual nerve, and glossopharyngeal nerve. The stimulation current generates action potentials on the cell membrane of the nerve entering the muscle abdomen and conducts along the axon. When it is transmitted to the swallowing and articulatory muscle groups, these muscle groups will be triggered and contracted in sequence, thereby enhancing the contraction motor function of the swallowing and articulatory muscle groups, relieving neuronal paralysis, promoting the recovery of paralyzed nerves, achieving the recovery and reconstruction of the swallowing reflex arc, and improving the patient's swallowing and articulatory activity.

l Product Features

1.Evaluation method

The entire evaluation process is automatically completed by the equipment until the final alpha value is formed, and the evaluation conclusion is given without the need for manual judgment.

2.Treatment method (passive)

Suitable for patients with severe swallowing disorders, divided into adult treatment mode and pediatric treatment mode. The patient receives pulse electrical stimulation therapy in a passive state to enhance the excitability of the swallowing muscles.

3.Training method (active)

Suitable for patients with mild swallowing disorders, it is divided into automatic triggering mode and manual triggering mode.

Automatic triggering mode: While the instrument rhythmically provides pulse electrical stimulation, the patient actively contracts the swallowing movement to train swallowing awareness.

Hand controlled trigger mode: The patient actively shortens the swallowing movement, while holding the controller to trigger pulse electricity in real time, stimulating the swallowing muscles and assisting themselves in completing the swallowing movement, in order to train swallowing muscle strength.

YS1002C Swallowing Nerve and Muscle Electrical StimulatorScope of application:

Suitable for evaluating, treating, and training swallowing and articulation disorders caused by non mechanical injuries to the pharynx.
