Description

High Frequency Stimulator Using Proximity Sensor

The present invention relates to a high frequency stimulator, and more particularly, to a high frequency stimulator used for the purpose of relieving pain in the musculoskeletal system and lipolysis in the field of skin beauty by applying a high frequency current to the human body to generate a body heat (deep heat).

In general, the human body has a number of acupuncture points, such as acupressure or massage to the acupuncture points, the cells radiate heat for defense, discharge the waste to the outside, which causes the acupuncture points.

Recently, such treatments have been developed, and physical therapy devices such as helium lamps and infrared lamps, thermal therapy devices for compressing and compressing affected areas, and high frequency stimulators using high frequency waves have been widely used.

The high frequency stimulator of the high frequency stimulator generates heat in the tissue when the high frequency current is supplied to the human body through the electrode inside the high frequency handpiece. This is called deep fever. This is because whenever high-frequency electrical energy is applied, the molecules constituting the tissues vibrate and rub against each other to generate bioheat due to rotational movement, distortion, and collision movement. High-frequency currents that do not stimulate the sensory and motor nerves can heat up specific areas of body tissues without causing discomfort or muscle contraction.

High-frequency energy converted into bio-thermal energy increases the temperature of tissues to promote cell function and increase blood flow.

In the prior art, a high frequency stimulator was generated by treating a high frequency in a high frequency handpiece.

Conventional high frequency stimulator has not been developed a function to supply or cut power to the high frequency handpiece. Thus, during the radiofrequency stimulation procedure to the user, there is a problem that the high frequency handpiece is separated by the operator so that the area of contact with the user's skin and the high frequency handpiece decreases, causing burns or sparks to cause side effects to the user.

In relation to the high frequency stimulator, Korean Patent Laid-Open Publication No. 10-2009-0065395 discloses a technique for confirming a contact area between high frequency and skin tissue, but for supplying power to the high frequency handpiece for more precise contact area control.

The high frequency stimulator 10 according to the present embodiment generates a high frequency to alleviate the swelling after surgery and muscle pain caused by excessive exercise or labor to alleviate the pain occurring in the user's body, and generates heat to the cold of the user's body It prevents abnormality of immune function caused by poor blood circulation by vascular contraction and sympathetic nerve operation.

And, it is possible to promote the recovery of wounds that can be caused by various factors.

When a high frequency current is applied to the human body, molecules constituting tissues vibrate and rub against each other to generate bio-heat by rotational movement, distortion, and movement. This is called deep heat.

Therefore, the high frequency stimulator 10 enhances the blood circulation of the user's body through the generation of deep heat through high frequency to increase immunity, alleviate various pains occurring in the body, and recover the wounds of the user's body. Will be promoted. In particular, it can be used for the purpose of alleviating the pain of the musculoskeletal system and fat melting in the field of skin beauty.

The RF generator 100 functions to generate a high frequency RF signal (high frequency signal) and provide it to the high frequency handpiece 200. Since a general RF signal output source (not shown) generates a weak signal, the RF generator 100 is configured to amplify the signal of the RF signal output source and provide it to the RF transmission cable 150.

In this case, the high frequency signal frequency may range from 0 MHz to 10 MHz.

The RF transmission cable 150 performs a function of providing a high frequency RF signal provided from the RF generator 100 to an electrode 250 installed in the high frequency handpiece 200 to be described later.

That is, the RF transmission cable 150 may be a general cable that serves as a transmission line, a coaxial cable may be used.

In addition, since the high frequency stimulator 10 according to the present embodiment should move the high frequency handpiece 200 freely, it may be preferable to use a flexible coaxial cable. Here, a cable having a characteristic impedance of the RF transmission cable 150 in the range of 50 ohm to 75 ohm may be used.

The high frequency handpiece 200 is formed in a conical shape, is connected to the end of the RF transmission cable 150, may be configured to perform a high frequency procedure on the affected part after the user grips.

An electrode for applying a high frequency signal generated by the RF generator 100 in contact with the epidermis of the affected part is provided at the distal end of the high frequency handpiece 200.

That is, the electrode 250 is in close contact with the skin and serves to irradiate high frequency power transmitted from the RF transmission cable 150 to the affected part.

Therefore, the molecules constituting the tissues are vibrated and rubbed with each other through high frequency radiation irradiated to the affected area, and as a result, heat is generated in the corresponding tissues.

The electrode 250 may be formed in any one shape selected from a flat round shape when viewed in a plane or a rod shape when viewed in a side view.

In addition, the electrode 250 is a replaceable use, in addition to the above-described shapes, it is possible to change the electrode of various shapes, including the shape of the rod, the shape of the step, etc. to suit the characteristics of the affected part.

Furthermore, the range of voltage applied to the electrode 250 is ?? 1 kV to +1 kV. The waveform of the voltage is a sinusoidal wave, which means a waveform combined from a trigonometric function.

Meanwhile, the ground pad 300 is connected to the RF generator 100 through a wire 170 as a neutral electrode. The ground pad 300 may be applied with current through the wire 170.

According to the high frequency stimulator 10 according to the present embodiment, the high frequency handpiece 200 is provided with a proximity sensor 400 so that the operator can treat the affected part (human body) of the patient with the high frequency handpiece 200. Proximity distance between lesions can be measured accurately.

The proximity sensor 400 is formed in a circular structure at the front end portion of the high frequency handpiece 200 and generates an ultrasonic signal to the human body of the patient to propagate into the air.

The propagated ultrasound signal is reflected from the surface of the human body of the patient, and a part of the ultrasound signal is detected by a receiver (not shown) formed in the high frequency handpiece 200.

Therefore, the proximity sensor 400 may calculate the distance between the high frequency handpiece 200 and the affected part by using a difference between the time of generating the ultrasonic signal and the time of detecting the ultrasonic signal.

3A is a schematic diagram illustrating a state in which the output electrode is operated because the high frequency handpiece of FIG. 2 is in the proximity sensor range. 3B is a schematic diagram illustrating a state in which the output electrode is not operated because the high frequency handpiece of FIG. 2 is outside the proximity sensor range.

First, as shown in FIG. 3A, four proximity sensors 400 may be configured at four front ends of the high frequency handpiece, and the number of the proximity sensors 400 is not limited thereto.

As such, the proximity sensor 400 may be formed in plural, and the proximity sensors 400 may be spaced apart from each other by a predetermined interval. In addition, each of the proximity sensors 400 may be disposed to form a predetermined angle.

Meanwhile, the high frequency handpiece 200 and the ground pad 300 contact the human body 30 to apply high frequency power to the human body 30 during the high frequency procedure.

At this time, when the proximity sensor 400 calculates the distance between the human body 30 and determines that the distance between the high frequency handpiece 200 and the human body 30 is within the measurement distance range 500 of the proximity sensor. Power is supplied to the electrode 250 of the high frequency handpiece 200 to apply high frequency to the human body 30 from the electrode 250.

In this case, the measurement distance range 500 of the proximity sensor is 0 to 10 mm and may be preset in the proximity sensor 400.

In contrast, as shown in FIG. 3B, when the high frequency handpiece 200 is out of the measurement distance range 500 of the proximity sensor due to an operator's mistake, the proximity sensor 400 is connected to the high frequency handpiece. The power supplied to the electrode 250 of the 200 is cut off so that a high frequency signal is not applied from the electrode 150 to the human body 30.

On the other hand, Figures 4a, 4b and 4c are schematic diagrams showing that the high-frequency handpiece of Figure 2 is used according to the use for the abdomen, leg joints and arm joints.

The high frequency stimulator 10 according to the present embodiment may stimulate and treat various parts of the human body including an abdomen and a joint.

As shown in FIG. 4A, the high frequency handpiece 200 and the ground pad 300 are in contact with the abdomen 31 of the patient, thereby generating high frequency heat in the abdomen 31 of the patient. By generating heat, the lipolytic effect of the abdomen 31 can be exhibited.
