Description

Technical Field

[0001] The invention relates to the technical field of medical devices, and in particular to a cold, hot and electric patterned cyclic stimulation rehabilitation device for swallowing dysfunction. Background Art

[0002] Swallowing disorder is a common complication of nervous system injury, and stroke is one of the most common diseases. After damage to the brainstem and the nerves that control the pharynx, the incidence and disability rate of swallowing dysfunction are high, which seriously affects the patient's quality of life. The incidence rate is 30%-78%. When the nerves that control the facial masticatory muscles, tongue muscles, pharynx, and epiglottis muscles are involved or when the above muscles are diseased, the movement of these muscles will be impaired, resulting in dysphagia, which can lead to complications such as food aspiration and suffocation. In severe cases, it may even endanger the patient's life. At present, swallowing disorders caused by common complications and sequelae of nervous system diseases use rehabilitation training as the main means of treatment, which is crucial for the recovery of patients' swallowing function. Correct rehabilitation training can prevent respiratory complications, shorten recovery time, reduce disability rate, and promote the maximum recovery of swallowing function. In clinical practice, rehabilitation exercises for swallowing dysfunction often use physical therapy instruments and hot and cold stimulation therapies, which can enhance the transmission of sensory nerve impulses before swallowing, making the area that triggers the swallowing reflex sensitive. Repeated stimulation promotes the recovery of the swallowing reflex and makes swallowing powerful. Stimulating the pharyngeal pressure receptors can achieve a good swallowing reflex effect and improve swallowing function.

[0003] However, currently, cold or hot stimulation for swallowing dysfunction is still commonly performed clinically using traditional cotton swabs to rub the swallowing muscles, or asking patients to try swallowing crushed ice and drinking hot milk for training. This is inefficient and has limitations for patients who cannot cooperate. Patients find it difficult to cooperate and tolerate it, and there is a high risk of aspiration during training. Currently, electrical stimulation of the swallowing nerve muscles mainly uses low-frequency electrical stimulation outside the mouth. For patients with true bulbar palsy such as insufficient or atrophied tongue muscles, weak or fibrotic pharyngeal constrictor muscles, the induction electrical movement method can stimulate the relevant muscles in the mouth, which has a certain therapeutic effect. The effect will be better when combined with conventional treatment. Currently, there are few related studies.

[0004] To this end, we propose a cold-hot-electric patterned cyclic stimulation rehabilitation device for swallowing dysfunction. This device targets the shortcomings of physical therapy instruments, combines ice or heat stimulation therapy, external electrical frequency stimulation of the throat and rehabilitation theory, makes training more targeted, achieves tongue pressure resistance training, improves tongue muscle strength, and improves swallowing coordination. At the same time, it has the advantages of being small and portable. It can not only perform targeted acupuncture on muscles outside the oral cavity, but also directly stimulate and treat organs inside the oral cavity such as the tongue and soft palate, making up for the limitations of surface electrical acupuncture, and making rehabilitation training safer, fundamentally reducing the incidence of adverse events in patients, adding an effective rehabilitation exercise method for the recovery of patients with swallowing dysfunction, reducing complications, and improving the quality of life of patients. Summary of the invention

[0005] The present invention provides a cold-hot-electric patterned cyclic stimulation rehabilitation device for swallowing dysfunction, which aims to solve the technical problems of effectively improving the swallowing function of patients with swallowing dysfunction caused by stroke, changing the limitation that patients with consciousness disorders cannot cooperate with rehabilitation treatment, avoiding aspiration caused by cold-hot swallowing training, improving the safety of rehabilitation training, enhancing the strength and endurance of the tongue lifting muscles, improving the strength of the tongue muscles, and improving the coordination of swallowing movements.
