Electrostatic medical and other multi-purpose devicesWith the rapid development of electronic technology, various electronic medical devices have emerged. According to its product functions, it can cure almost all diseases, but in fact it cannot cure a disease, it only has a few effects, which is mostly exaggerated. Just like there are many types of Western medicines, but few good medicines can cure the disease, which leads to the endless emergence of Western medicines to treat the same disease.As an electronic medical device, it should have a significant or even immediate effect on a certain disease in order to have practical value. "Electrostatic Medical and Other Multipurpose Devices" has this remarkable effect on treating tinea pedis and athlete's foot. The author has suffered from skin ringworm on his lower legs for 8 years. Treatment with various ringworm drugs not only failed to improve the condition, but instead expanded the area and intensified the itching and pain. However, the self-made "electrostatic medical device" was used for only 5 treatments, each time lasting no more than 5 minutes. The itching and pain decreased sharply. After 3 months, the itching and pain completely disappeared, and the skin remained intact, with no recurrence. Later, I also treated athlete's foot and toothache, and the results were even more immediate.After further experiments, it was found that the high-voltage electrostatic corona wind gently blows on the face and has the effect of skin care and beauty cream, which can keep the skin delicate and delay premature aging without any side effects.It can also be used to vacuum, deodorize, purify indoor air and preserve fruit and food. It is a multi-purpose product with practical significance.The principle, structure and usage of "Electrostatic Medical and Other Multipurpose Devices" are now introduced as follows.1. Circuit working principleThe circuit principle of electrostatic medical and other multi-purpose devices is shown in Figure 2-1. It is an inverter circuit composed of a unidirectional silicon-controlled SCR and a pulse transformer. It has few components and can operate normally without debugging.Figure 2-1According to the necessary conditions for the conduction of the unidirectional thyristor, during the positive half cycle of the power supply, the 220V AC power is half-wave rectified by the diode D1, and then provides positive voltage to the anode and control electrode of the unidirectional thyristor SCR through the step-down current limiting resistors R1, W and R2 respectively. As long as the potentiometer W is adjusted so that the voltage of the path reaches the trigger voltage of the control pole, the unidirectional thyristor SCR will be turned on, and the capacitor C will be discharged through the primary coil of transformer B and the unidirectional thyristor SCR. The greater the capacity of C, the higher the voltage induced by the secondary side of the transformer. When the supply voltage changes from the positive half cycle to zero, the unidirectional thyristor turns off because the current flowing through it is less than the holding current. After that, the unidirectional thyristor withstands the reverse power supply voltage and charges C with the opposite polarity. When the next positive half cycle arrives, the anode and control electrode of the unidirectional thyristor are re-conducted because positive voltage is applied to them. The capacitor C self-discharges, and reverse high voltage is induced in the secondary coil of the transformer. Repeatedly, the secondary coil of the transformer generates alternating high voltage. In other words, due to the frequent on and off of the one-way thyristor, high-frequency oscillation is formed, and a high voltage of 10,000 to 15,000V is induced on the secondary side of the pulse transformer. Changing the conduction angle of the unidirectional thyristor can change the output voltage.The alternating high voltage is rectified by the high-voltage silicon column D2, and a DC electrostatic high voltage is obtained. This electrostatic high voltage can be used in medical treatment, vacuuming and flocking, etc.2. Treatment principleStatic high voltage produces ozone and negative ions during discharge, and ozone and negative ions have extremely strong sterilizing capabilities and can also inhibit the reproduction and growth of fungi.Various diseases are mostly caused by fungi. If the fungi that cause the disease cannot be killed in time, the relevant parts will become inflamed until necrotic, becoming a base for fungi to multiply and thrive. Tinea dermatophytes is produced by this type of bacteria. Because it is on the surface of the skin and has a good air environment, it creates conditions for the survival and reproduction of ringworm, making tinea pedis a stubborn disease that is difficult to eradicate with general drugs.When electrostatic high-voltage sparks are used to stimulate the skin affected by ringworm, the ozone and negative ions produced by the electrostatic high voltage have a strong killing ability against the fungi that cause skin ringworm. It not only kills the bacteria, but also forms an ozone and negative ion layer at the affected area in a short period of time, surrounding the bacteria and inhibiting the resurgence and proliferation of the bacteria. At the same time, electrostatic sparks can enhance the bioelectricity of the lesion, enhance cell activity, and bring it back to life. In this way, after several electrostatic spark stimulation treatments, the killed ringworm and necrotic skin will gradually fall off and be replaced by new skin, leaving the ringworm skin intact as before.In the same way, it also has obvious pain-relieving and anti-itching effects in treating athlete's foot and toothache.When the corona wind of a high-voltage electrostatic field is used to gently blow on the face, the facial muscles immediately feel comfortable and relaxed. It has the effects of relaxing muscles, activating muscles, and anti-inflammatory and sterilizing effects, achieving the purpose of soft and anti-aging facial skin.3. Component selection and productionSCR is a one-way silicon controlled thyristor, which can be purchased in a plastic package with a specification of 1A/400V.For one-way thyristor, the following simple test can be done before use to determine its quality and pins.When the pins are not marked on the thyristor, the pins should be identified first. You can use the R×1K range in the ohm range of the multimeter to measure the resistance between each two pins in forward and reverse directions. It is found that the forward and reverse resistances between one of the pins and the other two pins are very large (a few hundred kiloohms or more). When the needle of the meter barely moves, the pin is the anode, and the remaining two pins are the cathode and control electrode. At this time, use the R×1K or R×100K range in the ohm range of the multimeter to measure the forward and reverse resistance between the two pins. Generally, the forward resistance between the control electrode and the cathode is tens to hundreds of ohms. If the forward resistance of the reverse resistance is slightly larger, then the measured resistance value is smaller. The pin connected to the black test lead (i.e. negative) is the control electrode, and the pin connected to the red test lead (i.e. positive) is the cathode. It should be noted that the forward resistance cannot be zero or greater than a few thousand ohms. A small reverse resistance does not mean that the thyristor is not good.When the pin polarity of the unidirectional thyristor is known, …
