Description

[Detailed Description of the Invention] [Object of the Invention] Sho 1''≦mm The civil engineering invention is directed to a low frequency treatment device that improves the pain relief effect by applying electrical stimulation to the affected area in synchronization with music. be.

lBei Zagen WataruThe conventional low-frequency treatment device was the Actual Public Notice of 1982-22.
A biological electrical stimulation device described in Japanese Patent No. 921 is known, and this device uses a recording medium that records a pulse pattern in which both or one of the pulse frequency and the duration of the same frequency changes irregularly. It has a structure that reproduces this recorded pattern, and a circuit that converts the reproduced signal into a stimulation signal, and is designed to irregularly change the frequency of pulses that stimulate the living body over time. In order to obtain such irregularly changing pulses, a recording medium such as a magnetic tape with a special pattern recorded thereon is required.
Creating and selecting such patterns is troublesome, and irregular stimulation changes that cannot be detected at all in the affected area may in some cases give unnecessary stimulation to the patient.
Also, when the recording pattern ends, the output will stop, so
This method has disadvantages such as unexpected stimulation acting on the patient when outputting starts again, giving the patient a sense of anxiety.

The sun is about to start. The invention is based on music cassettes, compact discs,
By using an arbitrary music signal such as a radio as a source of irregular output signals, irregular stimulation changes can be made to correspond to the patient's demands, and pulses at the fundamental frequency can be continuously output even when the music signal stops. The present invention aims to provide a low-frequency treatment device which allows the patient to relax on two levels by restoring sudden stimulation by stimulating the patient, and by making the patient listen to the music signal along with the low-frequency stimulation.

[Structure of the invention]

In view of these points, the present invention for reading fortune-telling includes: an audio device that allows users to listen to arbitrary music through an external sounding device such as headphones; and an amplifier circuit that amplifies the music signal in the audio device. A variable amplifier circuit that adjusts the input level of a music signal, an AC/DC converter circuit that converts an AC signal output from the variable amplifier circuit into a DC signal, and a voltage frequency that converts the DC signal output from the AC/DC converter circuit into a pulse wave. It consists of a conversion circuit and a pulse wave amplification circuit that amplifies the output pulse wave and outputs it to the affected area via a conductor.The pulse wave amplification circuit constantly oscillates a fundamental pulse wave of about 5 Hz and Maximum of approximately 6Q by matching the basic pulse wave to the amplitude of the music signal
It is an attempt to solve the above-mentioned drawbacks by providing a low frequency treatment device that can vary up to Hz.

The music signals obtained from each of the 11 sound devices are used for direct sound generation from an external sounding device and for changing the frequency of pulse waves, and the output pulse waves correspond to approximately 5
The pulse waves, which are varied from 11 Hz to 60 Hz and synchronized with the music signal, act as electrical stimulation while directly listening to music.
It acts on the colored parts.

1. Hereinafter, one embodiment of the present invention will be described based on the drawings. Reference numeral 1 is an audio device that outputs music signals such as music cassettes, compact discs, radios, etc. In the audio device 1, the volume etc. of each source can be adjusted. A music signal is extracted from an unaffected location and inputted to an amplifier circuit 28, and an external sounding device 3 such as headphones is connected to the audio device 1 so that the patient can directly listen to the music. .

Further, the output signal from the amplifier circuit 2 is introduced into a variable amplifier circuit 4 in order to correspond to the difference in the input signal level of each music signal, and the signal outputted through the variable amplifier circuit 4 is introduced into an AC/DC converter circuit 5. At least convert it into a DC voltage signal, introduce this DC voltage signal into a voltage frequency conversion circuit 6 to convert it into a pulse wave, and amplify this pulse wave by a pulse wave amplification circuit 7 to output a signal via a conductor etc. The voltage frequency conversion circuit 6 is configured to energize the human body.
Then, the timer of the device itself is always on about 5 hours.
In addition, the output signal from the voltage frequency conversion circuit 6 is made to oscillate a fundamental pulse wave of 5 Hz of the fundamental frequency, and the pulse wave of 5 Hz of the fundamental frequency is oscillated at a maximum of about 12 times the amplitude of the music signal.
The frequency is maintained within a range of approximately 0 Hz, and the width of the musical note is also set to always be 250 μsec.

The reason why the output frequency is set to approximately 5 Hz to 60 Hz is because at low frequencies below 5 Hz, it is not possible to respond to changes in the amplitude of the music signal over time, making it impossible to synchronize with the music. This is because it becomes difficult for the human body to sense changes in frequency, and the stimulation becomes too strong, giving the patient a sense of anxiety.

Effects of the Invention] In summary, the present invention comprises an audio device 1 that allows arbitrary music to be heard through an external sounding device 3 such as a horn, and an amplifier circuit 2 that amplifies the music signal in the audio device 1. , a variable amplifier circuit 4 that adjusts the input level of a music signal, an AC/DC converter circuit 5 that converts an AC signal output from the variable amplifier circuit 4 into a DC signal, and a DC signal output from the AC/DC converter circuit 5 into a pulse wave. Voltage frequency conversion circuit 6 that converts
and a pulse wave amplification circuit 7 that amplifies the output pulse wave and outputs it to the affected area via a conductor.The pulse wave amplification circuit 7 constantly oscillates a fundamental pulse wave of about 5 Hz and Since the fundamental pulse wave is made to correspond to the amplitude of the music signal and can vary up to a maximum of approximately 6011z, the music signal that is the basis of the irregular signal can be arbitrarily selected from music cassettes, compact discs, radios, etc. according to the patient's preference. The pulse wave output from the pulse wave amplification circuit 7 is a stimulation synchronized with the music signal selected by the person of color, and the user can also listen to music synchronized with the music signal applied from the external sounding device 3. This makes it possible to perform effective low frequency treatment in a very mentally relaxed state, and the fundamental frequency 5t (z pulse wave is always on even when the music signal ends when the timer is ON). Because it oscillates, even if the input signal suddenly changes from zero when inputting the music signal, it can prevent shocks caused by the sudden output of pulse waves, and the maximum output of pulse waves is approximately 60Hz. Since the upper limit is set, it does not cause more unpleasant stimulation to the patient than necessary, and the practical effects of the low-frequency treatment are greatly improved, such as significantly improving the effect of low-frequency therapy.
