Description
Technical Field
The utility model belongs to the technical field of medical appliances, and particularly relates to a percutaneous flexible electrical stimulation device and system based on multi-conduction electroencephalogram monitoring.
Background
The theory of traditional Chinese medicine holds that the meridians are channels of qi and blood of human body, viscera, limbs and bones can be connected together through the meridians, and the functions of all parts of the whole body can be regulated through the activities of the meridians, so that the normal operation of the meridians directly affects the health condition of the human body. The acupoints are the points on the body surface where the qi of the channels and collaterals is infused, and the purpose of treating the diseases related to the channels and collaterals and viscera is achieved by regulating the cold, heat, deficiency and excess of the channels and collaterals through the acupoints, so the acupoints are the points of the channels and collaterals on which the acupuncture treatment is clinically performed in traditional Chinese medicine. The acupoint therapy uses the theory of channels and collaterals as the mechanism, and uses electric energy, heat energy and the like to stimulate channels and collaterals, so that the qi and blood of a human body are unobstructed, the immunity of the human body is enhanced, and the purposes of preventing and treating diseases are achieved. Traditionally, the stimulation of the acupoints such as Shenmen, zusanli, yanglingquan, neiguan, yintang and Sanyinjiao can dredge the channels and collaterals, regulate the predominance and decline of yin and yang, and lead the organism to be in the secret of yin and yang, so as to achieve the effect of yin and yang balance and improve the sleeping quality. Research shows that acupuncture influences sleep duration, sleep time and sleep-wake cycle by regulating nervous system, neurotransmitter, inflammatory factor and biological clock genes, thereby improving sleep disorder.
Because acupuncture therapy generally has a certain pain feeling, even the phenomenon of needle dizziness or needle breakage occurs, and percutaneous acupuncture point electric stimulation therapy overcomes the defects of acupuncture and moxibustion, and is a convenient, safe and easily accepted acupuncture point stimulation mode. According to the acupoints of human body and the related detection method, the skin surface of the acupoints is subjected to low-frequency electric stimulation, which is helpful for the treatment and rehabilitation process of patients. The percutaneous acupoint electric stimulation Therapy (TEAS) combines the percutaneous nerve electric stimulation therapy with the meridian acupoint therapy, and applies a low-frequency current with a certain frequency to a specific acupoint to be input into a human body through skin so as to achieve the effect of treating diseases similar to acupuncture-electrotherapy.
The traditional Chinese medicine 'acupuncture-electrotherapy' or percutaneous acupoint electric stimulation therapy has certain limitations: stimulation points for treating insomnia are uncertain; the strength and parameters of the electric needle stimulation or the percutaneous electric stimulation are undefined in clinical use; the efficacy of either electrical needle stimulation or transdermal electrical stimulation cannot be verified; the traditional Chinese medicine electric acupuncture stimulation must go to a hospital to accept professional medical staff for treatment; most percutaneous electric stimulation devices or acupoint electric stimulation devices are required to be connected and used in a relatively troublesome manner.
