The display unit 20 is connected to the time control unit 106, the frequency control unit 108, and the safety setting unit 114.

Specifically, referring to FIG. 3, the display unit 20 includes a time display unit 200 for displaying a set time and a remaining time, a mode display unit 202 for displaying a selected mode such as continuous output and cross output, and a zero start. The zero start display sections 204 and 208 are provided. In addition, various stimuli are divided into output display units 206 and 210, 3 kHz, 7 kHz, 10 kHz, 0-30 kHz, 50 kHz, 0-50 kHz, 100 kHz and 0-100 kHz, which display output for each channel.

Then, the distance change volume 308 for setting the distance between the ceramic cup 60, the intermittent adjustment volume 310 for adjusting the output of the frequency when selecting the mode 3 to be described later, the balance adjustment volume for setting the balance of the output between the channels ( 312) and a stimulus output volume 314 for controlling the intensity output, and a power switch 316 for turning on / off the power of the low frequency stimulator 1 is provided.

5, the detailed configuration of the output unit 40 is shown. The output unit 40 is provided with magnetic pole output units 400, 402, 404, and 406 for generating stimulus outputs of the 'A' channel and the 'B' channel, and the motor 112 to form a vacuum in the ceramic cup 60. Pumping operation adjusting volume 408 for adjusting the time so that the vacuum is formed and stopped repeatedly when the pumping is performed by the pump), the vacuum pressure adjusting volume 410 for controlling the size of the vacuum formed in the ceramic cup 60, and The vacuum selection switch 412 for selecting whether to form the vacuum is formed. At this time, the pumping operation of the motor 112 can be largely divided into two modes, a continuous suction mode in which a continuous pumping operation is performed, and an intermittent suction mode in which suction is performed for a predetermined time and there is a little stop time therebetween. Divided into In the intermittent suction mode, the suction time is set to 1.8 seconds and the stopping time is set to 1 second, or the suction time is set to 4.2 seconds and the stopping time is set to 1 second.

The detailed function and operation of the low frequency stimulator 1 according to the embodiment of the present invention configured as described above will be described in detail.

After supplying power to the low frequency treatment device 1, the motor 112 is operated by pressing the vacuum selection switch 412 to form a vacuum in a state in which the conductor wire 50 is connected to the output unit 40. FIGS. The ceramic cup 60 is brought into contact with a specific part of the human body by moistening the circular sponge 68 shown in FIG. 6B. At this time, the suction pressure is appropriately adjusted by using the pumping time adjusting volume 408 so that an appropriate control operation is performed in the pump control unit 104.

The ceramic cup 60 is formed of a cup-shaped cover 62, the terminal 64 is connected to the upper end of the cover 62, the low-frequency output is transmitted, the motor 112, A hole 66 penetrated inside the cover 62 is formed in order to form a vacuum by driving of the cover 62. In addition, the through holes 70 are formed at regular intervals on the edge portion of the circular sponge 68.

At this time, the ceramic cup 60 is a magnetic pole output unit 400, 402, 404, 406 to form an 'X' around the affected area as the 'X' to form the 'stimulus output to interfere, and the distance change volume 308 When the distance between the ceramic cup 60 is set by the internal interference, the ceramic cup 60 is to form a 'II' side by side up and down.

The basic principle of the stimulus output in frequency mode is to use a modulation frequency by interfering a 4000 sine wave with a 4000 s + a sine wave. The frequency range of the modulation frequency is 0 to 100 ㎐. That is, the fundamental frequency changes from 3900 kHz to 4000 kHz. Examples of output waveforms in the case of applying such a modulation frequency are shown in Figs. 7A and 7B. Such output is controlled by the value set in the output control unit 102, the waveform and intensity, the operation time is adjusted by the operation time set in the time control unit 106.

First, according to FIG. 7A, an output form in which a frequency mode having a size of 10 kHz is selected is shown, and low frequencies having a magnitude between a variable frequency 3990 kHz and a fixed frequency 4000 kHz are continuously output. In addition, according to FIG. 7B, the fixed frequency 4000 kHz and the variable frequency 4000 ˜3900 kHz are shown in an output form in which a frequency mode having a size of 0 to 100 kHz is selected.

At this time, as described above, the continuous output mode 1, the 'A' channel and the 'B' channel 2 are outputted at the intersection, and the intermittent control volume 310 in the form of the continuous output and the cross output is mixed. It is divided into Mode 3 (intermittent output) which is operated to adjust the output of frequency. In this way, one of three output modes is set, and a desired frequency is set using the frequency selection button 302. Then, the value is set in the frequency control unit 108 and the output of the frequency is provided accordingly. The output form from Mode 1 to Mode 3 is shown in Figs. 8A to 8C.

That is, FIG. 8A illustrates the case of Mode 1 which is a continuous output, and low frequencies having a constant magnitude are output. FIG. 8B is an example of Mode 2 in which low frequencies having a predetermined time period, for example, a 1 second period are cross-outputted, can be seen that there is a phase difference between the 'A' channel and the 'B' channel. 8C shows an example of Mode 3 in which the 'A' channel and the 'B' channel have intermittent outputs of the same period.

Then, check whether the stimulus output volume 314 is placed at '0' and gradually increase the stimulus intensity at '0' to use the best output intensity felt by the patient, and the output of 4000㎐ and 4000㎐ + a is balanced. Adjust the balance adjusting volume 312 to achieve.

At this time, if an error occurs such that the ceramic cup 60 is removed from the affected part or the power is not supplied suddenly, the low frequency stimulator 1 should be operated again, and the stimulus output volume 314 is set to the '0' position. The ceramic cup 60 is attached to the affected area again to operate. Otherwise, the error display unit 214 lights up due to a misoperation of the user to inform an error. That is, the zero start safety setting unit 114 is operated.

The safety setting unit 114 supplies an appropriate error signal to the display unit 20 so that the status thereof is displayed when the error occurs, and also supplies an error signal to the time control unit 106. Then, the time controller 106 implements a zero start so that the error signal is fed back to the output controller 102 so that an operation state starts from an initial state.

Then, when the set use time is completed, a sound indicating the end sounds, and the low frequency stimulus output is cut off.

As described above, according to the embodiment of the present invention, the output of the low frequency is appropriately selected according to the user's state by selecting various frequency channels, and the cross output is made, so that there is an advantage that a more effective treatment effect can be obtained. . In addition, there is an advantage that can protect the user from the electric shock during use is designed to be zero start.

According to the present invention, even if an error occurs during use, the zero start is made, and the safety of the user by the safety setting unit to block the supply of the overcurrent has the effect of ensuring the safety.

In addition, the frequency channel is diversified so that the output frequency of a different size can be supplied according to the health state of the user, so that a wide range of stimulation can be selected, and the cross-output is made, thereby achieving a faster treatment effect.

In addition, since a certain size of vacuum is formed in the ceramic cup so that the ceramic cup is not separated from the affected part, an error in using the apparatus by the ceramic cup may be prevented.
