Side effects of intermediate frequency therapeutic instrument The intermediate frequency therapeutic instrument is a new type of physical therapy instrument which combines modern electronics and magnetic therapy with traditional Chinese medicine viscera images and meridian science. It stimulates human acupuncture points by conducting current with specific frequency through thermoelectromagnetic contacts, thus producing therapeutic effects of hyperthermia, acupuncture, electrotherapy and magnetic therapy. Compared with the low-frequency therapeutic instrument, the medium-frequency therapeutic instrument has obvious effect, weak skin tingling, strong sense of depth and long needle retention time.
But the therapeutic instrument is used to treat diseases, and the electronic therapeutic instrument should have corresponding safety protection functions. If the safety of the therapeutic instrument itself is not good, it may cause new physical harm to consumers. The dealer said? Very safe? At the same time, consumers can quickly identify whether it has some important safety protection functions by browsing the instruction manual of the instrument or simply operating the instrument.
However, due to the unstable load, the current of intermediate frequency therapeutic instrument will fluctuate greatly during the treatment, which may not only damage the instrument, but also cause electric shock to the patient, and the safety of treatment is not good. The instrument does not meet the stability requirements in the current industry standards. The therapeutic instrument has no short circuit protection function and no constant current source output function. The short-circuit protection function is to protect the therapeutic instrument from being damaged by short-circuit of the output line, and the output function of the constant current source is to protect the user, so that the output current will not fluctuate greatly and ensure the safety of treatment.
Introduction of intermediate frequency therapeutic instrument The intermediate frequency therapeutic instrument is a simulation of acupuncture in traditional Chinese medicine, which uses pulse current controlled by CPU to dredge blood vessels and nerves and achieve smooth communication.
In a certain frequency range, the impedance of human tissue is inversely proportional to frequency, that is, the impedance of human tissue to intermediate frequency current is lower than that of low frequency current, so intermediate frequency current can reach deeper parts of tissue than low frequency current, and the skin feels comfortable. The intermediate frequency current itself has a certain therapeutic effect, and the low frequency modulated intermediate frequency current has a comprehensive effect of low frequency and intermediate frequency, and the effect is better. Intermediate frequency therapeutic instrument can output 2 ~ 8 kHz intermediate frequency current, including and synthesizing various therapies of intermediate frequency electrotherapy.
The intermediate frequency current of the intermediate frequency therapeutic instrument can enter the deep tissue of human body and will not strongly stimulate cutaneous nerves and receptors. When a strong intermediate frequency current is added to the valve, there is only a slight friction feeling at first, and there is a tingling feeling when the current is large. The greater the current, the more obvious this feeling is. However, when the power is turned on continuously, this feeling gradually fades away. Only when the current intensity is high, there is an uncomfortable sense of bondage.
Coupled with a strong enough intermediate frequency current, it can cause a strong contraction of muscles. It has been proved that the threshold of muscle contraction is much lower than that of pain valve in the intermediate frequency range of 2000-8000Hz. Therefore, using this frequency can make muscles contract strongly without causing pain.
How to use the intermediate frequency therapeutic instrument 1 Turn on the power supply, the output knob should be at zero position, the patient should take a comfortable position, expose the treated part, and pay attention to keep warm in winter;
2. Select the electrode and polar plate, and determine the placement method. First, soak the pad with water, and the metal plate shall not directly contact the patient's skin; 3, slowly increase the current until the patient's maximum tolerance;
4. During the treatment, according to the adaptability of the patient, the current intensity can be gradually increased or decreased to the patient's tolerance;
5. After the treatment, slowly reduce the current to zero, turn off the power supply, remove the electrode plate, tidy up the equipment, put it in order, and wipe it clean for later use.
