Description

an acupuncture needle

technical field

The utility model belongs to the technical field of medical equipment, in particular to an acupuncture needle.

Background technique

Acupuncture and moxibustion medicine is an important part of traditional Chinese medicine therapy. Under the guidance of traditional Chinese medicine theory, acupuncture needles are inserted into the human body at a certain angle and depth, and the specific acupuncture points of the human body are stimulated by twisting, lifting and inserting techniques to achieve therapeutic effects. Patients do not need to take drugs internally. No toxic side effects. Acupuncture and moxibustion medicine has a long history and is enduring. It is deeply loved by people and is still used by people today.

In the process of acupuncture and moxibustion treatment, sometimes people need warm needling or fire needling treatment, that is, the needle body needs to be heated to improve the therapeutic effect. The traditional warm needling method is to add a moxa column at the end of the needle, and after being ignited, the heat will be transmitted through the needle body to the Inside the body, the traditional fire acupuncture treatment is to heat the needle body first and then quickly pierce the needle into the human body while it is hot, so as to increase the temperature of the human tissue around the needle body. The deficiency that these two kinds of treatment methods exist is that temperature is difficult to control, easily burns human body skin, and operation is inconvenient.

In modern acupuncture and moxibustion, acupuncture needles based on the principle of heat conduction, that is, external heating and internal heating electric acupuncture needles, have improved the shortcomings of traditional acupuncture to a certain extent, but the outer wall of the external heating electric heating acupuncture needle is attached to the electric heating component. , the heat is transferred to the human tissue through the needle rod, resulting in a high temperature of the needle rod outside the body surface, which is easy to burn the human skin, and the temperature rise of the human body tissue is difficult, while the internal heating type electric heating acupuncture needle is equipped with an electric heating wire in the hollow needle body, resulting in The outer diameter of the needle is relatively large, and the production cost is high.
