Problems solved by technology

Traditional 8-shaped or double 8-shaped coils, as well as Slinky coils are difficult to meet the requirements of acupoint magnetic stimulation in terms of stimulation depth and focus, and are only suitable for cortical magnetic stimulation
[0006] In addition, the existing rehabilitation stimulation devices currently adjust the stimulation according to the patient's subjective feeling and the doctor's experience.
For patients who have lost the ability to communicate with the outside world, it is easy to cause excessive stimulation or insufficient stimulation intensity, which cannot achieve effective and optimal treatment, and even cause additional trauma
In addition, the adjustment of stimulation methods by medical staff is based on experience, and the effect of stimulation on patients cannot be quantified, and real-time dynamic adjustments are made according to the quantitative results, which makes it difficult to achieve the expected therapeutic effect

Embodiment 1

[0036] A meridian magnetic stimulation system for brain α-wave feedback adjustment according to the present invention mainly includes three parts: a magnetic stimulation generator, an electroencephalogram and a computer. The schematic diagram of the system work is as follows: figure 1 shown. First, apply a certain magnetic stimulation signal to act on the acupoints of the human body, and perform magnetic stimulation on the acupoints of the human body (at this time, the α wave of the brain will change). The electrical signal is sent to the computer to analyze the power spectrum of the alpha wave of the brain, calculate the energy of the alpha wave of the brain, and draw and display the dynamic EEG map of the alpha wave. At the same time, the magnetic stimulation intensity, stimulation frequency and stimulation waveform are adjusted according to the brain α wave energy feedback to achieve the best magnetic stimulation effect on meridians.

Embodiment 2

[0066] Embodiment 2 utilizes the α-wave dynamic EEG topographic map drawn in Embodiment 1. By observing the EEG topographic map in real time, the manual adjustment button in the magnetic stimulation generator is used to send control instructions to the single-chip microcomputer. The single-chip microcomputer system controls the magnetic stimulation generator. Stimulation intensity, stimulation frequency and stimulation waveform can be adjusted.

[0067] The α-wave EEG topographic map of the brain is used as the basis for manual adjustment of magnetic stimulation parameters, and can be used in conjunction with α-wave automatic feedback to adjust stimulation parameters. By manually adjusting the stimulation intensity, stimulation frequency or stimulation waveform, the α wave energy of the subject's brain is in a higher range, which is indicated by the maximum red area on the topographic map.

Abstract

The invention provides a cerebral alpha wave feedback regulation acupoint magnetic stimulation system. The system consists of a magnetic stimulation generating instrument, an electroencephalograph and a computer. According to the system, a trumpet-shaped stimulation coil of the magnetic stimulation generating instrument is fixed on an acupuncture point of a human body to magnetically stimulate, the electroencephalograph is used for acquiring electroencephalograms, and the electroencephalogram data processing computer analyzes the power spectrum of a cerebral alpha wave and computes the energy of the cerebral alpha wave, draws and displays a dynamic brain electrical activity mapping; and the stimulation intensity, stimulation frequency and stimulation waveform are respectively and automatically regulated in a feedback manner and manually regulated according to the energy of the electroencephalogram cerebral alpha wave and the dynamic brain electrical activity mapping so as to obtain an optimum acupoint stimulation effect. The system can promote the nervous system recovery of cerebral palsy patients and the autonomous rehabilitation training of acroparalysis patients.

Description

technical field [0001] The invention belongs to the technical field of rehabilitation medical equipment, and relates to a meridian magnetic stimulation system for brain alpha wave feedback regulation. Background technique [0002] Currently, physical rehabilitation methods for patients with cerebral palsy and paraplegia mainly use acupuncture, functional electrical stimulation and other methods. Functional electrical stimulation therapy uses stimulating electrodes to act on specific parts of the patient to restore some of the patient's motor functions and speed up recovery. However, whether it is functional electrical stimulation therapy or acupuncture therapy, it will cause pain and trauma to the patient, and it needs to rely on the patient's subjective feelings and the doctor's experience. The qualitative stimulation input method will inevitably affect the effect of rehabilitation treatment. [0003] Magnetic stimulation technology generates instantaneous pulse stimulatio...
