Description

Technical Field

[0001] The utility model belongs to the technical field of medical equipment, and particularly relates to an acupoint electrical sensitization symmetry detection device. Background Art

[0002] Acupoint sensitization refers to the process of acupoints transforming from a "quiescent state" to an "activated state". That is, when a disease occurs in the human body, the acupoints related to the disease will undergo morphological and functional changes. Morphological changes include local color changes, shape changes, papules, etc. Functional changes include pain sensitization, electrical sensitization, photosensitization, thermal sensitization, sound sensitization, and microcirculation sensitization. At this time, the strength and range of the acupoint function will change. Effectively identifying this change and applying it in a clinical environment plays an important role in the diagnosis and treatment of diseases.

[0003] Electrosensitization refers to the state in which the skin potential, resistance, potential difference, conductivity value, etc. of the acupoints change (increase, decrease, imbalance, etc.) when a disease occurs. We believe that when the electrosensitization state of the acupoints with the same name on both sides is asymmetric, the body will be in or tend to a pathological state. Therefore, in clinical practice, there is a need for an objective method to judge the symmetry of the acupoint state and a treatment device that can achieve simultaneous treatment of the main and auxiliary acupoints. Currently, the acupoint electrosensitization instruments on the market mostly diagnose diseases based on the state of unilateral acupoints / meridians, and cannot achieve synchronous detection of the electrosensitization state of the left and right acupoints, thereby judging the disease by the balance of the electrosensitization state of the left and right acupoints.
