Description

Technical Field

[0001] The present invention relates to the technical field of traditional Chinese medicine rehabilitation medical devices, and in particular to a gastrointestinal therapeutic device based on acupoint electrical stimulation. Background Art

[0002] Gastrointestinal dysfunction is one of the most common functional diseases of the digestive system in clinical practice. With the advancement of the times, a complete diagnostic system has gradually been formed, and the understanding of functional gastrointestinal diseases has gradually evolved from a binary regression model to a more comprehensive bio-psycho-social model. At present, in terms of instrumental treatment of gastrointestinal functional diseases in clinical medicine, low-frequency electrical stimulation (1-20Hz) can inhibit sympathetic nerve excitability and enhance vagus nerve activity, thereby improving intestinal motility and visceral hypersensitivity, while high-frequency stimulation (50-100Hz) is more effective in relieving acute pain. However, existing electrical stimulation therapeutic devices mostly target single acupoints or general parameters, and do not optimize acupoint combinations and stimulation parameters based on the pathological characteristics of gastrointestinal dysfunction; and most devices lack real-time physiological signal monitoring (such as abdominal muscle tension and skin resistance), and cannot adjust the stimulation intensity and frequency according to changes in visceral sensitivity during treatment, resulting in limited efficacy. There is a lack of dynamic identification and targeted stimulation of positive abdominal reaction points (such as tenderness, nodules, etc.); there is insufficient personalized matching of TCM syndrome differentiation (such as liver depression and spleen deficiency, spleen and stomach damp heat, etc.) and electrical stimulation parameters; for example, the abdominal massager described in patent CN202410260622 achieves physical pressing and hot compress through an adsorption cavity and acupoint pressing parts. Although it can stimulate the Tianshu acupoint, it lacks the precise control ability of electrical stimulation and cannot dynamically adjust parameters according to individual differences.

[0003] Combined with the efficacy of TCM acupoints, it can be seen that the skin nerves in the Shenque area are richly distributed. Stimulating this point may affect the activity of the vagus nerve through the surface-visceral reflex, regulate gastrointestinal motility and secretory function, and relieve gastrointestinal spasm and functional disorders; while stimulating Taiyi helps to dredge the stomach meridian qi, harmonize the rise and fall of the stomach organs, and relieve abdominal fullness and pain caused by qi stagnation; and Daju point is an important acupoint for regulating intestinal function (especially the lower abdomen); stimulating Daju point can promote intestinal peristalsis, relieve intestinal spasm, reduce abdominal pain and diarrhea of ​​diarrhea-type irritable bowel syndrome (IBS-D), improve abdominal distension, and reduce the feeling of fullness in the lower abdomen. Direct stimulation of this point can affect the nerve innervation and blood circulation of the local colon, and bidirectionally regulate intestinal smooth muscle activity.

[0004] Therefore, this paper proposes a gastrointestinal therapeutic device based on acupoint electrical stimulation. Summary of the Invention
