Description

Single point electroacupuncture method and device

technical field

The invention relates to an electroacupuncture method and device based on a single acupoint, belonging to the technical field of medical instruments.

Background technique

Acupuncture therapy is a therapy that uses the functions of human meridians and acupoints and certain needling techniques to treat systemic diseases from the outside to the inside. As an important part of traditional Chinese medicine, acupuncture has played an important role in the health care of our people for thousands of years. According to reports, acupuncture can effectively treat more than 300 diseases, of which more than 100 have remarkable effects. At present, acupuncture therapy has gradually been popularized all over the world due to its advantages such as significant curative effect, definite effect, economy, safety, and small side effects.

Since the 1960s and 1970s, the combination of traditional hand acupuncture and low-frequency pulse electrical stimulation has produced electroacupuncture therapy. Compared with hand acupuncture, electroacupuncture uses pulsed electrical stimulation instead of manual needle movement, which saves manpower and is more convenient to operate. At the same time, it can control the stimulation dose more objectively, reducing the requirements for acupuncturists. After decades of practice, the effectiveness of electroacupuncture therapy has been fully verified, and its clinical application has become increasingly widespread. At present, there are two main implementation methods of electroacupuncture: one is to use acupuncture needles pierced into acupoints as stimulating electrodes; the other is to use planar skin electrodes pasted on acupoints for stimulation, also known as acupoint transcutaneous electrical stimulation. Both implementations require the selection of pairs of acupoints to form a current circuit. When performing electro-acupuncture stimulation, the pulse current flows from the positive electrode into an acupoint, passes through meridians and other tissues between acupoints, and then flows out from another acupoint.

When using electroacupuncture to treat diseases, some diseases only need several treatments, but some chronic diseases, especially chronic nervous system diseases, such as pain, Parkinson's disease, Alzheimer's disease, depression, drug addiction, etc. Long-term or even mandatory treatment. In this case, the above two electro-acupuncture implementation methods are both cumbersome and difficult to persist for a long time. Therefore, researching new electroacupuncture methods, developing convenient percutaneous electroacupuncture devices, and developing electroacupuncture treatment devices that can be implanted in the body and work on their own will greatly improve the stability and reliability of electroacupuncture therapy while reducing the risk of electroacupuncture. The complexity of the operation has important medical significance and application prospects.

At present, there is no research report on single-acupoint electroacupuncture methods and devices in China. In the prior art, US Patent Nos. 5,094,242 and 5,211,175 disclose a device for implanting electroacupuncture. Circuit and needle electrode; the overall scheme of US Patent 6,377,853 is the same as the above-mentioned patent, but some improvements have been made, including the use of multi-strand twisted wire as the wire of the needle electrode to improve the softness, and the needle electrode and the receiving circuit are packaged A protective device is added to the interface of the shell to prevent the interface from being damaged and broken, and a fixing measure is added near the electrode contact to prevent the electrode from being displaced.

The above-mentioned patent is only an attempt of implantable electroacupuncture stimulation, and does not involve the method of single acupoint stimulation; moreover, there are many defects in the application of the above-mentioned scheme, for example, the electrode design uses needle-type electrodes. It will inevitably cause harm to patients during use, so there is not much practical application value.
