Description

A device that stimulates muscle scaling

technical field

The invention relates to a muscle relaxation device, in particular to a device which utilizes electric current to stimulate pain points to scale muscles.

Background technique

Due to the accelerated pace of people's life and the decrease in activity, many muscle diseases have occurred. Myofascial pain is a common muscle disease. According to statistics, the prevalence of myofascial pain is quite high, accounting for about 14.4% of the global population. Symptoms of myofascial pain include muscle tightness, soreness, weakness, and more. There will be tender points, tension bands, and conduction pain when the muscles are touched. Myofascial pain is not fatal, but it is quite annoying and can easily become a chronic disease that affects the patient's quality of life.

The current treatment methods for myofascial pain mainly include drug therapy, rehabilitation therapy and lifestyle changes. Medications use non-steroidal pain relievers, muscle relaxants, and more. Rehabilitation treatment includes hot compress, interference wave, hydrotherapy, stretching exercise, relaxation exercise, muscle tape, and physiological feedback training. Change your lifestyle to a regular life, regular exercise, and relaxation.

However, long-term drug treatment is prone to side effects. The process of rehabilitation treatment is quite long, and the effect varies from person to person. The effect needs to be improved by changing the lifestyle.

Contents of the invention

In order to solve the above-mentioned defects in the prior art, the object of the present invention is to provide a device for stimulating muscle scaling. The present invention induces muscle contraction by introducing micro-current into a specific excitation point of the muscle, so as to relieve muscle tension.

To achieve the above object, the present invention adopts the following technical solutions:

The device for stimulating muscle expansion is suitable for human body. This device includes dedicated pins and a host. The special needle is made of conductive metal, the outer layer of the special needle is coated with some insulators, so that the needle tip is exposed outside the insulator, and the special needle is electrically coupled to a signal line. The needle tip of the special needle is exposed outside the insulation, and the surface is not coated with insulation. In addition, the host is coupled to the dedicated pins via the aforementioned signal lines. Insert the special needle into the target point in the muscle to a depth of D cm, where D is a real number. The control signal is sent to the dedicated needle through the signal line, so that the micro-current is introduced into the target point of the muscle, so that the muscle can be scaled.

Due to the adoption of the above technical solution, compared with the existing muscle relaxation device, the device for stimulating muscle scaling of the present invention has the following beneficial effects: the excitation of micro-current is used to promote muscle scaling, so as to relieve muscle tension, and has no side effects, and has the effect of relaxing muscles better.

After the device of the present invention is used to stimulate muscle scaling in patients with myofascial pain, the regular electrical stimulation can cause the muscles to contract and then relax, so that the normal muscle tissue outside the excitation point can restore its original tension and no longer spasm. In addition, stimulating muscle scaling can remove local muscle edema and metabolites, and take away the water, creatinine, calcium and other metabolic substances originally accumulated in the muscles, thereby reducing the impact on the pain nerves and the nuclear bag and nucleus that cause spasm reflexes. Chain (nuclear bag and nuclear chain fiber) nerve fiber stimulation. In addition, repeated fixed-frequency contraction at the excitation point can consume the release of excitatory acetylcholine at the muscle-nerve junction, thereby reducing the contraction strength of muscle cells and reducing the degree of spasm. Repair of injured or inflamed tissue is accelerated due to rapid relaxation of spasmed muscles. On the other hand, the trigger point tissue belongs to the damaged muscle nerve junction structure, and the microcurrent has the ability to promote cell regeneration and restore abnormal tissue to normal function. Microcurrent can also gradually ablate the fibrotic and adherent tissue in the long-term painful area, allowing normal muscle tissue to grow and recover. Moreover, the inactive repetitive muscles contract obviously, which drives the contraction and relaxation of the smooth muscles of the dermis, and the microvascular circulation of the epidermis at the treatment site is also enhanced.

In order to make the purpose, features, and advantages of the present invention more obvious and understandable, the following will be described in detail in conjunction with the accompanying drawings:

As shown in FIG. 1 , a schematic structural diagram of a device for stimulating muscle scaling according to a preferred embodiment of the present invention. The device for stimulating muscle scaling includes a needle 102 and a host 104 . Wherein, the host 104 includes an operating unit 106 , a control unit 108 , a driving unit 110 and a display unit 112 . Wherein, the needle body 102 is electrically coupled to the host 104 via the signal line 114 . Furthermore, the control unit 108 is coupled to the operation unit 106 , the driving unit 110 and the display unit 112 .

As shown in FIG. 2 , a schematic structural diagram of a special needle according to a preferred embodiment of the present invention. The needle body 102 includes a special needle 202 , an insulator 204 and a needle shaft 206 . Wherein, the special pin 202 is made of conductive metal, the head of the special pin 202 is conical, and the special pin 202 is electrically coupled to the signal line 114 . The outer layer of the special needle 202 is coated with some insulators, so that the needle tip is exposed outside the insulators. Furthermore, the tip of the special needle 202 is exposed outside the insulator, and the surface of the tip is not coated with an insulator. The area over which the tip 208 of the special needle 202 protrudes from the tip of the insulator 204 is 0.2 mm ² to 0.4 mm ² .

As far as human muscles are concerned, when using a device that stimulates muscle scaling, the needle body 102 is inserted into a target point in the muscle, and the penetration depth is D cm, where D is a real number. Then, the control signal is sent to the special needle 202 through the signal line 114, so as to guide the micro-current into the target point of the muscle, so that the muscle can be scaled. After the special needle penetrates into the muscle, the sensory nerve located in the superficial skin touches the insulator 204, and the needle tip of the special needle 202 directly touches the target point. Therefore, when the micro-current is introduced into the target point of the muscle, the human body will not feel soreness or numbness.

Among them, the target point is the medical trigger point (Trigger Point). Furthermore, the control signal is a DC pulse wave. According to the optimization results of clinical experiments, the frequency of DC pulse wave is 2Hz to 200Hz. The pulse width of the DC pulse is 400 microseconds (μsec) to 1000 μsec. The microcurrent is a constant current from 1 milliamp (mA) to 25 mA. After the control signal acts for 2 minutes to 5 minutes, stop the output. The medical principle of the device that stimulates muscle scaling is to relax the deep muscle taut band, make the muscle blood circulate, block the neuromuscular junction of the excitation point, and destroy the local micro-adhesive tissue.

In a clinical experiment, 870 patients with myofascial pain were stimulated with a device that stimulates muscle scaling. According to the statistical results, if the pain perception coefficient is set as 10 points, 83.15% of the patients feel immediate improvement after the stimulation, 16.85% of the patients do not improve, 31.54% of the patients improve by one point, and 26.16% of the patients improve by two points , 25.45% improved by more than three points. One week after the stimulation, 80.25% of the subjects improved consciously, 19.75% did not improve, 28.4% improved by one point, 16.05% improved by two points, and 35.8% improved by more than three points.

The device that stimulates muscle scaling is used to stimulate muscle scaling in patients with myofascial pain, and the brain MRI examination is performed. The results show that the activity of the pain management area (around the cerebral aqueduct) in the patient's brain has increased, indicating that the muscles are stimulated. After zooming, it can affect the pain activity of the brain center. Devices that stimulate muscle contraction have been shown to not only relax the muscles but also have a central pain suppressing effect.
