Description

[Detailed Description of the Invention] [Technical Field] The present invention provides a biostimulation device that generates interference waves inside a living body by applying two electrical output waves generated by two oscillation means with different phases or periods to the living body. Regarding.

[Prior art]

Conventionally, this type of biostimulator is equipped with two oscillation means to generate interference waves, and it is necessary to accurately maintain the difference in frequency output from these oscillation means. Methods using analog oscillators such as AC oscillators require complex circuit configurations to generate electrical output waves that maintain accurate frequency differences.

〔the purpose〕

The present invention has been made in view of the above points, and an object of the present invention is to generate stable interference waves by simply and accurately providing means for oscillating different frequencies.

〔composition〕

Embodiments of the present invention will be described below with reference to the drawings.

In FIG. 1, a high frequency signal output from a first oscillator 1 is connected to an input of a first frequency divider 2 and an input of an exclusive OR gate 4. The output of the first frequency divider 2 is connected to the input of the first output means 5. The low frequency signal output from the second oscillator 1' is connected to the input of the delay means 3. The output of the delay means 3 is connected to the other input of the exclusive OR gate 4, and the output of the exclusive OR gate 4 is connected to the input of the second frequency divider 6. The first frequency divider 2 and the second frequency divider 6 both have a function of dividing the frequency by 1/T. The output of the second frequency divider 6 is connected to the input of the second output means 7. The first output means 5 and the second
The output means 7 generates alternating waves having amplitudes corresponding to the input pulses, and outputs them to output terminals g and h, respectively. Each of the output terminals g and h is provided with a conductor provided with means for forming an interface with a living body.

Next, the operation of the embodiment showing the above configuration will be explained with reference to FIG.

The output signal of the first oscillator 1 is frequency-divided by a first frequency divider 2 to generate the signal shown in FIG. 2e.

The output signal of the second oscillator 1 (FIG. 2b) is converted into a delayed signal (FIG. 2c) by the delay means 3. When this delayed signal and the signal output from the first oscillator 1 (FIG. 2a) are input to the exclusive OR gate 4, the signal shown in FIG. 2D is output.

In Fig. 2 d, the frequency is divided by the second frequency divider 6 in the same way as the first frequency divider, but since pulses 3P and 9P are added in Fig. 2 d, the pulse of 1 pulse is The width becomes smaller and the image shown in FIG. 2 f is output.

The frequency-divided signals generated by the first frequency divider 2 and the second frequency divider 6 are transmitted to the first output means 5 and the second output means 7, respectively.
An alternating wave having a predetermined amplitude is generated here. The alternating wave outputted from the output end g of the first output means 5 has the waveform shown in FIG. 2g, and the alternating wave outputted from the output end h of the second output means 7 has the waveform shown in FIG. An alternating wave having the following values will be output.

The present invention includes four conductors, ie, two pairs of connected conductors and unrelated conductors. By attaching each conductor to the human body, alternating waves with different frequencies output from each output means are energized in the living body, and at the point where these alternating waves intersect in the living body, low frequency interference waves are generated. is generated.

In the above embodiment, pulses were added to the output of the first oscillator in accordance with the output of the second oscillator, but the pulses may be deleted instead.
