A display unit 17 is provided at the center. The handle 5 is provided with an endless rotatable strength dial 18 on the right side and a speed dial 19 on the left side. Here, the strength dial 18 can display 0 to 15 levels, and the speed dial 19 can display 1 to 15 levels on the display unit 17.
[0010]
FIG. 2 is a circuit diagram of the low-frequency treatment device according to this embodiment. In terms of circuit, this low frequency treatment device includes a power supply circuit 22 including a battery 21, a booster circuit 23 that boosts the voltage of the power supply circuit 22 to about 100 V, a microcomputer 24, a strength dial 18, a speed dial 19, and the like. operation switch section 25 including the key switch, the transistor Tr _1, Tr _2, ......, applied voltage control unit 26 including the Tr _5, the transistor _{Tr 6, Tr 7, Tr 8} , ......, waveform shaping and outputs including Tr ₁₁ and a current detection unit 28 including the parts 27 and transistor Tr _12,. The electrodes 2 and 3 are connected to the jack 29 of the output unit 27.
[0011]
Signal d ₁ from the microcomputer 24, ..., the state of d _5, the transistors Tr _1, ..., Tr ₅ is ON / OFF, resistor entering parallel to the boosted power supply is switched selected, the electrodes 2 and 3 The applied voltage is adjusted. When the signal d ₆ is output from the microcomputer 24, the transistor Tr ₆ is turned on during that time, and when the signal d ₇ is output, the transistor Tr ₇ is turned on, and the high voltage direct current is waveform-shaped and the jack 29 is turned on. Then, positive and negative alternating pulse voltages are applied to the electrode and the affected part of the living body.
[0012]
Further, the microcomputer 24 reads signals from the strength dial 18 and the speed dial 19 of the operation switch section 25, and the electrode 2 connected to the jack 29 is supplied with a pulse voltage of strength and speed corresponding to the reading. 3 is applied.
In this embodiment of the low frequency treatment device, assuming that the mode selection by the operation switch unit 25 is the “slap” mode, a pulse signal of several tens Hz shown in FIG. And the treatment site is energized. However, with only a pulse signal of several Hz, the pain-relieving effect is weak although there is tapping stimulation. Therefore, as shown in FIG. 3B, a 1200 Hz pulse signal having the same strength is inserted between the pulse signal of several Hz and the pulse signal of several tens Hz. That is, a pulse of several tens Hz and a pulse of 1200 Hz are alternately repeated and applied to the electrodes 2 and 3 from the jack 29. With such a pulse signal application pattern, it is possible to give a pain relief effect with a pulse of 1200 Hz while receiving a tapping stimulus by a pulse of several Hz.
[0013]
In addition, the application mode of the pulse of several Hz to several tens Hz and the pulse of several hundred Hz to 1200 Hz is a stimulus of several hundred Hz to 1200 Hz in a situation where a pulse of several Hz to several tens Hz is generated and output. A group of pulses having a frequency that has a pain-relieving effect with little feeling may be inserted or output at arbitrary or constant intervals. On the contrary, in a situation where pulses of several hundred Hz to 1200 Hz are generated and output, a pulse group having a stimulation feeling of several Hz to several tens Hz may be inserted and output at arbitrary or constant intervals. .
[0014]
Further, in the above description, in the case of FIG. 3B, the pain relief effect is obtained with a continuous pulse of 1200 Hz, and the stimulation feeling is obtained with a pulse of several Hz to several tens of Hz (time point t ₁ ). In fact, when a pause period is set by a continuous pulse of 1200 Hz, a tactile sensation is also obtained at the time t ₂ rising at the end of the pause period, and a continuous pulse of 1200 Hz having a pulse of several Hz to several tens Hz and a pause period. In the superimposition, two stimulation feelings t ₁ and t ₂ are obtained (see FIG. 4A).
[0015]
Further, as shown in FIG. 4B, when a continuous pulse of several hundred Hz to 1200 Hz has a pause period T and this T is several tens of milliseconds or more, at the rising point t2 of the continuous pulse. A feeling of irritation can be obtained, and a pain relief effect can be obtained by applying a continuous pulse.

The low-frequency treatment device of this embodiment includes a first waveform shaping section 27-1 and a second waveform shaping section 27-2, each receiving the output of the oscillation circuit 23, and the first waveform shaping section 27-. A pulse signal of several Hz to several tens Hz is output from 1, and a pulse signal having a frequency of several hundred Hz to 1200 Hz is output from the second waveform shaping unit 27-2. Each of the first waveform shaping unit 27-1 and the second waveform shaping unit 27-2 includes a peak value adjusting unit and a frequency adjusting unit, and can independently adjust the peak value and the frequency. The outputs of both waveform shaping sections 27-1 and 27-2 are added to the output section 27b and are given to the electrodes in a superimposed manner. Therefore, when a pulse of several tens Hz in the “slap” mode and a pulse of 1200 Hz are continuously superimposed, the waveform is as illustrated in FIG. Here, the case where the peak value of a pulse of several tens of Hz is larger is shown. Also in this case, it is possible to feel the pain-relieving effect with a continuous output of 1200 Hz pulses, and the tapping stimulation with a pulse whose amplitude protrudes at several tens of Hz.
