Description

A device for treating insomnia and anxiety by percutaneous electric stimulation of Shenmen point

technical field

The utility model belongs to the technical field of physical therapy devices for rehabilitation medicine, in particular to a device for treating insomnia and anxiety by percutaneous electrical stimulation of Shenmen acupoint.

Background technique

At present, there is no device for percutaneous electrical stimulation of Shenmen acupoint to treat insomnia, and the existing technology of Shenmen acupoint and insomnia, electrical stimulation for insomnia and anxiety, and percutaneous electrode design methods are introduced as follows:

(1) Shenmen point and insomnia

Shenmen acupoint is one of the acupoints of the Heart Meridian of Hand Shaoyin. It is located on the wrist, at the ulnar end of the transverse crease on the palm side of the wrist, and in the radial depression of the flexor carpi ulnaris tendon. Shenmen acupoint is one of the acupoints often used in acupuncture and moxibustion. It is traditionally believed that this acupoint can calm the mind and calm the mind, calm the mind and regulate qi. Shenmen has obvious therapeutic effects on mental diseases. Among the acupuncture points selected for clinical treatment of sleep disorders, anxiety and depression, Shenmen is the most frequently selected main acupoint for insomnia, with a frequency of 69.16%. Li Xiaomin and others believe that although acupoint pressing is not an invasive operation, it also has the effect similar to acupuncture and moxibustion. Yang Xiaomei et al. reported that massaging Shenmen acupoint can improve the bad mood of hospitalized patients with coronary heart disease and significantly improve the sleep quality of patients.

(2) Electrical stimulation for insomnia

Insomnia is the most common sleep disorder disease, manifested as difficulty in falling asleep, maintaining deep sleep and inability to recover energy and physical strength after waking up, thereby affecting normal work and life. Long-term chronic insomnia may also be complicated by depressive affective disorder or lead to physical diseases, etc., seriously affecting the quality of life of patients. The pathogenesis of insomnia is still unclear. It is generally believed that there is a sleep-inducing area in the brainstem, and the weakening of inhibitory effect or enhanced facilitative effect of neurons in this area can lead to insomnia. Drugs are currently the main method for the treatment of insomnia, but most hypnotic drugs have tolerance and dependence, and cannot be used for a long time. Low-frequency pulse electrical stimulation has the effect of sedation and hypnosis. Studies have shown that the treatment of Du Channel and Bladder Meridian through low-frequency electrical stimulation can achieve the effect of calming the mind and sleeping. Research by Chen Yi and others confirmed that the stimulation of acupoints by low-frequency electrical pulses can affect the activity of the central nervous system and the production of certain chemical substances such as serotonin and dopamine through the regulation of peripheral nerves and blood vessels, thereby achieving a calming and tranquilizing effect.

(3) Design method of percutaneous electrode

Transcutaneous Electrical Acupoint Stimulation (TEAS) is a combination of modern medical transcutaneous electrical nerve stimulation (TENS) and acupuncture points, through the skin-specific low-frequency current input to the human body to achieve similar effects to acupuncture. Transcutaneous electrical stimulation overcomes some of the disadvantages of acupuncture, such as pain during acupuncture, fear of needles, and susceptibility to infection. The waveforms of transcutaneous electrical stimulation are single-phase square wave, bidirectional square wave, asymmetrical square wave, etc., which are characterized in that instantaneous power-on and power-off are not easy to cause polarization, and the body adapts very slowly. The electrodes are generally made of round or square non-woven materials, the skin surface is made of conductive silica gel, and the wiring surface is made of metal materials, which are connected with wires. When performing electrical stimulation therapy, a pair of electrodes are attached to the corresponding parts of the skin surface, and after setting the electrical stimulation parameters, the treatment can be implemented.

To sum up, it has been shown in the prior art that stimulating Shenmen acupoint has a therapeutic effect on sleep disorders, anxiety and depression. Compared with acupuncture, massage, electroacupuncture and other methods, transcutaneous acupoint electrical stimulation is the most convenient, effective and safe acupoint Stimulus way. However, the existing technology also has certain limitations: one is that the electrodes have a large conductive area, and the stimulation site is not precise enough; the other is that there is no electrical stimulation generator specifically for the treatment of insomnia and anxiety.
