Description

Technical Field

[0001] The present invention relates to the technical field of acupuncture, and specifically relates to an automatic acupuncture device. Background Art

[0002] Acupuncture adjusts the functions of qi and blood and zang-fu organs by stimulating the body surface acupoints and through the conduction of the whole body meridians, so as to achieve the purposes of "strengthening healthy qi and eliminating pathogenic factors" and "treating diseases and maintaining health". Because acupuncture does not require taking medicine and the patient can leave immediately after treatment, and has good health care effects, it has played an increasingly important role in modern family medicine.

[0003] In the traditional acupuncture method, doctors usually disinfect the acupuncture needles manually. Before use, they wipe the needle tips with alcohol. This disinfection method is not thorough enough. After that, the doctor needs to find the corresponding acupoints of the patient, hold the needle and slowly insert it into the patient's body surface, and then pick up another needle to find the position and insert it. In this way, for each needle inserted, another needle needs to be picked up, which is time-consuming and laborious. Moreover, during the use process, there is a risk of cross-infection, and the safety performance is low. Manual disinfection also has the hidden danger of secondary infection. At the same time, the determination of acupoints depends entirely on the doctor's experience. For doctors with insufficient experience, it is easy to have inaccurate positioning or slow positioning, reducing their work efficiency. And it is also impossible to judge the accurate insertion depth during insertion. Therefore, how to overcome the above-mentioned technical problems and defects has become the key problem to be solved. Summary of the Invention
