Problems solved by technology

The problem it has is that the paste-type electrodes have a large area and inaccurate acupoint selection. Electric pulse stimulation is only performed on the surface of the human skin and cannot enter the deep layer of the human body. It is difficult to obtain good curative effect.
The problem it has is that two acupoints must be pierced to connect the positive and negative electrodes to form a current path and generate electrical pulse stimulation.
[0008] The above-mentioned existing electroacupuncture has the following deficiencies: 1. The existing electroacupuncture treatment that uses low-frequency pulse current to stimulate acupoints through filiform needles, so that ions in human tissues can undergo directional movement, the basis for controlling the direction of pulse current, that is, how to There are no specific and clear regulations on control, and there is a certain degree of blindness, so if two acupoints are selected, the direction of the current is not easy to determine
2. The existing electroacupuncture distributes the current evenly from the needle body to the needle tip in the human tissue, and the tiny current pulse cannot be completely concentrated on the needle tip, so that a good therapeutic effect cannot be achieved
3. Due to the current passing between the needle body and human tissue, it will cause unnecessary current stimulation to subcutaneous cells, tissues or organs, and even damage them; the current on the needle body will also electrolyze the tissue fluid, causing the needle body to be corroded

Abstract

The invention discloses an asychronous multi-channel stimulation electric acupuncture needle and a preparation method thereof, and belongs to the technical field of medical instruments. The acupuncture needle comprises an acupuncture needle and cylindrical electrode assemblies at two ends, wherein a corresponding laminated metal coats on each cylindrical electrode assembly, and one end of the corresponding laminated metal is provided with a stimulation electrode, while the other end is provided with a welding point; and each cylindrical electrode assembly comprises an insulating layer positioned on an inner layer, a conductor layer positioned in the middle and a protective glue polymer block positioned on an outer layer. Each stimulation electrode on the prepared acupuncture needle is short, the stimulation electrode current distribution is concentrated, the treatment effect is good, and the acupuncture needle can avoid injuring other body structures and tissues as possible.

Description

technical field [0001] The invention relates to an electroacupuncture needle in the technical field of medical equipment and a preparation method thereof, in particular to an asynchronous multi-channel stimulation electroacupuncture needle and a preparation method thereof. Background technique [0002] Acupuncture and moxibustion is one of the most effective methods of treating diseases in traditional Chinese medicine. Clinical studies have proved that acupuncture and moxibustion can be widely used in various diseases such as internal medicine, external medicine, gynecology, children, nerves, five sense organs, skin, and tumors. Modern acupuncture and moxibustion studies point out that diseases that occur for any reason are caused by the stagnation and rigidity of cells. The stagnation and rigidity of cells are related to the reduction and disappearance of natural substances. The substance returns to the original place, restores the function of the cell, dredges the ion chan...
