[Medium Frequency Therapeutic Apparatus]The working principle of the medium frequency therapeutic apparatus The impact on the human body is also different. Scientific research has shown that low and intermediate frequency current will bring certain benefits to the human body. Therefore, there are low and intermediate frequency therapeutic apparatuses on the market. So what is the role of the intermediate frequency therapeutic apparatus? Will there be any side effects if used for a long time?
The full name of the medium frequency therapeutic apparatus is “low frequency modulation medium frequency therapeutic apparatus”, which contains 1~150Hz low frequency current and 2~8KHz medium frequency current, and has certain effects on common osteoarthritis and lumbar disc herniation.
Relatively speaking, the medium frequency therapy device is a safe physical therapy device. It has the characteristics and functions of both low-frequency and medium-frequency currents, which are easier for the human body to accept and adapt to, thereby analgesia, promoting blood circulation and lymphatic return, and regulating autonomic nerve function.
The medium frequency therapeutic apparatus is suitable for neurology and has a certain effect on patients with migraine; it is suitable for otolaryngology and obstetrics and gynecology, which can treat certain infectious diseases and chronic diseases; it is suitable for gastroenterology, It has a certain therapeutic effect on certain diseases of the gastroenterology department; it is suitable for patients with frozen shoulder and lumbar disc herniation, and has analgesic effect.
The working principle of the medium frequency therapeutic apparatus
The medium frequency therapeutic apparatus simulates traditional Chinese medicine acupuncture and uses the pulse current controlled by the CPU to target the acupuncture points. Drain blood vessels and nerves to achieve the effect of smooth transmission.
In a certain frequency range, the impedance of human tissue is inversely proportional to the frequency, that is, the impedance of human tissue to intermediate frequency current is lower than that to low frequency current, so intermediate frequency current can reach deeper tissue than low frequency current. area, and the skin feels comfortable. The intermediate frequency current itself has a certain therapeutic effect, and the intermediate frequency current modulated by the low frequency has the comprehensive effect of the low frequency and the intermediate frequency, and the effect is better. The intermediate frequency therapeutic apparatus can output intermediate frequency current of 2~8kHz, which includes and integrates various treatments of intermediate frequency electrotherapy.
The intermediate frequency current of the intermediate frequency therapy device can enter the deep tissue of the human body without strongly stimulating the cutaneous nerves and receptors. When the intermediate frequency current of the valve strength is added, there is only a slight rubbing feeling at first, and only when the current is large. Needle-prick feeling, the greater the current, the more obvious this feeling is. But when the power is continued, this feeling gradually weakens. The uncomfortable feeling of restraint can only be felt when the current is large.
Adding a strong enough intermediate frequency current can cause strong muscle contraction. It has been confirmed that in the intermediate frequency range of 2000-8000 Hz, the threshold of muscle contraction is much lower than the pain threshold. Therefore, using this frequency it is possible to make muscles contract strongly without causing pain.
Side effects of the medium frequency therapeutic apparatus
The medium frequency therapeutic apparatus is a modern electronic, magnetic therapy and traditional It is a new type of physiotherapy instrument that combines TCM viscera and meridian science. It stimulates the acupuncture points of the human body by conducting electric current of special frequency through thermo-electromagnetic contacts, thus producing the therapeutic effects of hyperthermia, acupuncture, electrotherapy and magnetic therapy. Among them, compared with the low frequency therapeutic apparatus, the intermediate frequency therapeutic apparatus has obvious effect, and the skin tingling sensation of the intermediate frequency is weak, which achieves the effect of a strong sense of depth and a long needle retention time.
However, the therapeutic apparatus is used to treat diseases, and the electronic therapeutic apparatus should have corresponding safety protection functions. If the safety of the therapeutic device itself is not good, it may cause new physical damage to consumers. When the dealer says “very safe”, consumers can quickly identify whether it has some important safety protection functions by simply browsing the instruction manual of the instrument or simply operating the instrument.
However, during the treatment process of the intermediate frequency therapy device, the current will fluctuate greatly due to the instability of the load, which may not only damage the device, but also cause electric shock to the patient, and the safety of the treatment is not good. . This instrument does not meet industry standard requirements for current stability. The therapy device has no short circuit protection function and no constant current source output function. The short-circuit protection function is to protect the therapeutic apparatus from damage due to the short-circuit of the output line, and the constant-current source output function is to protect the user, and the output current will not be too large or too small to ensure the safety of the treatment.
How to use the IF therapeutic apparatus
1. Turn on the power, the output knob should be at zero The patient should take a comfortable position, expose the treatment site, and keep warm in winter;
2. Select electrodes and pads, and determine the placement method. First wet the pad with water, and the metal plate should not be directly Contact with the patient’s skin;
3. Slowly increase the current until the patient’s maximum tolerated dose;
4. During the treatment, the current intensity can be gradually increased or decreased according to the patient’s adaptability Tolerance;
5. After the treatment, slowly reduce the current to zero, turn off the power, remove the electrode plate, arrange the equipment, put it in order, wipe it clean, and set aside.
