Question 2: What is radiofrequency therapy? Radiofrequency treatment is the application of high-power short-wave or microwave effect on the human body, the use of its electromagnetic energy in the body heat, so that the body of ions and charged colloid vibration to produce conduction current, while the capacitance field in the body of the dipole orientation, rotation, and the displacement current, thus forming the endogenous heat to achieve the purpose of treatment of pain. Radiofrequency action on the organism can lead to vasodilation, accelerated circulation of blood and lymphatic fluid, increased permeability of capillaries and cell membranes, increased activity of intracellular enzymes, and improvement of the pelvic internal environment. Metabolism is accelerated. Enhance the function of immune system such as white blood cells, antibodies and complement, inhibit and kill certain pathogenic microorganisms, so as to achieve the purpose of anti-inflammation and swelling reduction. Applicable to a variety of acute and chronic soft tissue injuries, arthralgia, neuralgia, cervical lumbar and leg pain, pneumonia, pelvic inflammatory disease, frozen shoulder, tennis elbow, tenosynovitis, tendonitis, ligamentous inflammation of the knee, rheumatoid arthritis, etc. .

The treatment head is very light, the operator's grip is close to the electrodes and the skin, and it is not easy to be fatigued. Octopole treatment head is used for body treatment and diamond treatment head is used for face treatment. Single-stage radiofrequency: positive and negative two stages
Question 5: What is radiofrequency therapy? What are its advantages and disadvantages? Radiofrequency therapeutic instrument for lumbar and cervical disc herniation effect depends on the choice of indications, especially for cervical spine herniation effect is particularly good for patients with low cost, less pain. The treatment can be repeated.
Question 6: RF uses [edit this paragraph] The concept of RF
RF transceiver core circuit RF that Radio Frequency, usually abbreviated as RF. indicates that can be radiated into the space of the electromagnetic frequency, the frequency range from 300KHz ~ 30GHz between. Radio Frequency is abbreviated as RF RF is radio frequency current, which is a high-frequency alternating current changes in electromagnetic wave short. Changes per second less than 1000 times the alternating current is called low-frequency current, more than 10000 times is called high-frequency current, and radio frequency is such a high-frequency current. The cable television system is radical to use radio frequency transmission. In the theory of electronics, the current flows through the conductor, the conductor around the formation of a magnetic field; alternating current through the conductor, the conductor around the formation of an alternating electromagnetic field, known as electromagnetic waves. In the electromagnetic wave frequency is lower than 100khz, electromagnetic wave will be absorbed by the ground, can not form an effective transmission, but electromagnetic wave frequency is higher than 100khz, electromagnetic wave can be propagated in the air, and by the outer edge of the atmosphere of the ionosphere reflection, the formation of long-distance transmission capability, we have a long-distance transmission capability of high-frequency electromagnetic waves called radio frequency, radio frequency technology in the field of wireless communications is widely used.
[Editorial] Introduction to common units of RF calculation
Various common units of RF calculation are one of the necessary basics to understand the concept of RF in depth.
Absolute power
Absolute power of dB indicates that the absolute power of the RF signal is commonly used dBm, dBW, it and mW, W conversion relationship is as follows: For example, the signal power is x W, the use of dBm to indicate the size of: RF commonly used units of calculation Introduction to the e.g.: 1W is equal to 30dBm, is equal to 0dBW.
Relative Power
Relative power of dB that the relative power of RF signals commonly used dB and dBc two forms of expression, the difference is: dB is the ratio of any two power logarithmic form of expression, and dBc is a frequency output power and carrier frequency output power ratio of logarithmic form of expression.Antenna and antenna gain
Antenna gain is generally expressed by dBi or dBd. dBi is the antenna relative to the ratio of the power energy density of the antenna directionless antenna, dBd refers to the ratio of the power energy density relative to the half-wave oscillator Dipole, the half-wave oscillator gain is 2.15dBi, so 0dBd = 2.15dBi.
Other commonly used units of calculation
RF Principle Resistance: an object or substance that blocks the passage of electric current, thereby converting electrical energy into heat or other forms of energy, in ohms, Ω Voltage: potential or potential difference, in volts, V Current: the number of charges per unit of time that pass through a defined point on a circuit, in amperes, A Inductance: the thing that the coil surrounds, usually a wire, which, because of the Inductance: the coil surrounded by something, usually a wire, due to electromagnetic induction, the coil can produce electric potential energy, unit: Henry, H Capacitance: a charge of insulated conductive objects potentially have the maximum rate of charge, unit: Farad, F
[Edit paragraph] RF technology classification
Automatic Identification Technology
Automatic Equipment Identification Technology is currently the international development of a new technology very quickly, the name is Automatic Equipment Identification, or AEI for short. Automatic Equipment Identification, referred to as AEI. The basic idea of this technology is to use some advanced technical means to realize the people of all kinds of objects or equipment (personnel, goods) in different states (mobile, static or harsh environment) under the automatic identification and management. At present the most widely used automatic identification technology can be roughly divided into two aspects: optical technology and radio technology. One of the optical technology in the general application of the products are: bar code and camera two categories. These two types of products have been widely used in people's daily life, and has been known to people. For example, barcode is used for commodity management, and camera is used to capture illegal vehicles.
Radio frequency recognition technology
Radio frequency recognition technology can be divided into two categories of low frequency system and high frequency system according to the frequency difference; according to the electronic label is equipped with a battery for its power supply, can be divided into two categories of active and passive systems; from the electronic label to save the information injected into the way can be divided into the integrated circuit curing type, on-site wired rewrite type and on-site wireless Rewrites three big categories; According to reads the electronic label data the technical realization method, may divide it into the broadcast emission type, the frequency multiplication type and the reflection modulation type three big categories. 1. The low frequency system generally refers to its working frequency is less than 30MHz, the typical working frequency has: 125KHz, 225KHz, 13.56MHz and so on, these frequency points apply the radio frequency recognition system generally has the corresponding international standard to support. ...... >>
Question 7: Radiofrequency electrotherapy is used in the hpv virus what does it mean Radiofrequency therapy is the application of high-power short-wave or microwave effect on the human body, the use of its electromagnetic energy in the body to generate heat, so that the body of the ions and the vibration of the charged colloid to produce conduction currents, and at the same time, capacitance field in the body of the dipole orientation, rotating and generating displacement currents, which form the endogenous heat to achieve the treatment of pain. The purpose is to treat the pain.
