Description
Technical Field

Background
Acupuncture has been developed to the current thousands of years, is an important component of Chinese traditional medicine, is precious wealth of national culture and science tradition, and has the effects of dredging channels and collaterals, harmonizing yin and yang, strengthening body resistance to eliminate pathogenic factors and the like. In traditional Chinese medicine, the channels and collaterals are better than a connecting net, so that viscera and body surfaces of a human body are combined into a whole body, and the functions of the whole system are adjusted. Stimulation of the acupoints of this system may have regulatory, conditioning and therapeutic effects.
Acupuncture is now well known and accepted by many more people both domestically and abroad. Although the advantages and features of acupuncture are obvious, there are also very obvious limitations. Acupuncture is a specialized skill, and requires a high skill to perform a needle, which is generally mastered by only some professionals, so that it is difficult to popularize the acupuncture in a large scale. The application of electronic acupuncture solves the problem. Traditional acupuncture is performed by applying needles to corresponding acupoints and mechanically stimulating the acupoints after diagnosis of the etiology of traditional Chinese medicine. This requires a high level of expertise and skill, which is difficult for the average person to master. The electronic acupuncture is to stimulate the acupoints by using the electric pulse mode with specific waveform, and replace the mechanical stimulation by using the electric current mode to achieve the aim of acupuncture. The requirements on the skill of needle application are greatly reduced, and general staff can apply the needle for symptoms by means of the meridian point map, so that the needle is convenient for more users to use.
Electronic acupuncture is generally performed by using an electronic acupuncture therapeutic apparatus, and an output interface of the apparatus is applied to a human body through a connection wire and a conductive needle. During treatment, multiple paths are usually needed to act on a human body at the same time, and because the tail end of a wire and a needle body are not insulated, or the wire is aged for a long time, the condition of short circuit of an output loop is easy to occur.
