Description

[Detailed explanation of the invention] Industrial application field This invention is used to improve mental concentration, improve morale, and treat psychogenic diseases by suppressing cerebral consciousness alteration, that is, calming the activity of the cerebral cortex. The present invention relates to a treatment device for inducing an altered state of consciousness, which is used in a treatment method to restore homeostasis of the mind and body.

Prior Art As a prior art, there is Japanese Patent Application Laid-open No. 106438/1983. This publication includes means for obtaining a biological signal from the human skin and generating a first notification signal when the α-wave signal extracted from the biological signal exceeds a predetermined magnitude. , a biological return device is disclosed which includes means for generating a second notification signal for increasing the alpha wave signal when the alpha wave signal is not exceeded.

Problems that the invention aims to solve Brain wave components include gamma waves, beta waves, alpha waves, theta waves, and delta waves. Taking the generation of alpha waves as an example, alpha waves that begin to be generated in one part of the brain gradually It then spreads throughout the brain and occurs in multiple locations. When detecting brain waves using electrodes attached to the scalp, there are no individual differences in the amplitude of the brain waves at the source, but there are individual differences in the amount of attenuation when they pass through the skull, skin, etc. Since differences in the contact resistance of the electrodes are also added, there are individual differences in the amount of α waves detected.

In addition, since the electrodes detect α waves that occur in multiple phases, the voltage level changes slightly due to the voltages of each phase canceling out or adding to each other, but overall the voltage level has a characteristic that there is little change over time. be.

The device disclosed in Japanese Patent Application Laid-open No. 60-106438, presented as a conventional technique, detects alpha waves from an electrode attached to the scalp, in view of the above-mentioned mechanism of brain wave generation, in which the amplitude of alpha waves detected from electrodes attached to the scalp changes very little over time. It is not possible to accurately determine whether a large amount of alpha waves are being emitted from the brain by dividing the amplitude component into whether it reaches a predetermined threshold value or not. Therefore, in a device that first gives an encouraging signal so that more alpha waves are produced, and then gives learning information when more alpha waves are produced to make the patient learn effectively, it is difficult to determine whether or not the patient is producing a lot of alpha waves. There were problems in that the determination could not be made correctly, and if the α-wave level fluctuated frequently, the driving of the two tape players would have to be switched many times, making it impossible to perform effective learning.

Furthermore, learning information is given except when the amplitude of alpha waves reaches a threshold, but when learning information is given, the conditions in which brain waves are generated change, and the amplitude of alpha waves often decreases, and beta waves and gamma waves increase. Occurs often. In such a situation, there was a problem in that the learning information was switched to the encouraging signal while the learning information was being given, making it impossible to perform satisfactory learning.

Means for solving the problems This invention solves the problems of conventional devices.
The purpose of the present invention is to provide a therapeutic device for inducing an altered state of consciousness that can accurately detect the occurrence of alpha waves in a patient, provide therapeutic sounds when alpha waves occur frequently, and effectively treat the mind.

That is, the present invention includes a frequency detector 4 that counts the number of occurrences of alpha waves extracted from human brain waves, a frequency comparator 5 that compares the arbitrarily set frequency and the output of the frequency detector 4, and a frequency comparator 4 that counts the number of occurrences of alpha waves extracted from human brain waves.

Effect: Treatment under altered consciousness as a means of removing stress and restoring cerebral homeostasis is based on the old cerebral cortex, which is formed by childhood, in the cerebral cortex, namely appetite, sexual desire, and group desire. , etc., and the new cerebral cortex formed through subsequent learning, that is, the stress that occurs between the functions of the neocortex, which governs creation, intention, thinking, perception, understanding, cognition, etc. The new cerebral cortex's critical ability is dulled, the old cerebral cortex is activated only, and the new cerebral cortex's inhibitions are removed, while giving suggestions and stimulation to release and relieve the stress of the past. (desensitization). Depending on the depth of degeneration, human consciousness can be divided into a motor-dominated stage, a sensory-dominated stage,
It changes into each stage, from the memory-dominated stage to the sleepwalking state stage. As the degree of these altered consciousness deepens to the motor control stage, sensory control stage, memory control stage, and sleepwalking state stage, the alteration of consciousness due to suggestions and stimuli also deepens, and stress relief becomes easier. It becomes easy to forget.

An increase in the frequency of occurrence of alpha waves means that the patient's altered state of consciousness has deepened, and patients in such a state are highly suggestible, and suggestions are easily made under the altered state of consciousness. Therefore, a condition in which alpha waves appear frequently is first introduced, and then treatment is administered, and this device is used to perform this introduction and treatment. The outline of the operation of this device is to attach an electroencephalogram detection guide 1 to the patient's head, detect brain waves with the electroencephalogram detection guide 1, amplify the brain waves with a preamplifier 2,
The amplified brain waves are filtered by an alpha wave detection filter 3 to extract alpha waves of 8 to 12 Hz, and the frequency of appearance of the extracted alpha waves is determined by a frequency detector 4 and a frequency comparator 5. If the number of occurrences of alpha waves is large, the therapeutic audio tape player 9 is driven to generate therapeutic audio for the patient to hear. In addition, if the number of occurrences of α waves is small, deepening signal tape player 1
0 to generate a signal that promotes the appearance of alpha waves in the patient and deepens the deterioration of consciousness, and the patient hears it.

Next, the functions of the number detector 4 and the number comparator 5 will be explained in detail.

When the α wave shown in FIG. 2A is input to the frequency detector 4, the frequency detector 4 counts the number of waves of the α wave during a predetermined period, that is, the number of times the α wave appears. The number comparator 5 compares the output of the number detector 4 with the set number set by the reference number setter 17 operated by an external signal such as a magnetic tape signal, and determines that the output of the number detector 4 exceeds the set number. When this happens, a signal is output to one output terminal 6, and when the number of outputs does not exceed the set number of times, a signal is output to the other output terminal 7. For example, if the set number of times is set to 5, the number of occurrences of the alpha wave in Figure 2A exceeds 5 between t ₂ and t ₃ , so it will appear a short time after t ₃ as shown in Figure 2 B. On the other hand, an output signal is output to the output end 6, and the therapeutic audio tape player 9 is driven.

Also, between t ₀ and t ₁ , the number of alpha waves that appear is 3, and between t ₁ and t ₂ , the number of alpha waves that appear is 4.
Therefore, only the other output terminal 7 of the number comparator 5 emits a signal between times t ₁ and t ₃ . Therefore, as shown in FIG. 2C, the deepening signal tape player 10 starts operating a short time after time _t1 until the output signal of the number comparator 5 switches to one output terminal 6, that is, immediately after time _t3. The deepening signal tape player 10 continues to operate until.

When the patient is deemed to be in a state suitable for treatment, an output is generated only from one output end 6 of the number comparator 5 by automatic operation using an external signal such as a signal from the magnetic tape of the reference number setting device 17. Alternatively, output may be generated from one output terminal 6 for an appropriate period of time. With this output, the therapeutic audio tape player 9 is driven continuously or for an appropriate time,
Treatment can be carried out continuously or over time.

In the second embodiment shown in FIG. 3, among the outputs of the frequency comparator 5 that often repeat ON and OFF, the number of ON outputs is counted by the input frequency integrator 11 and set in advance. The therapeutic voice tape player 9 is driven only when the number of times reached is reached, and the deepening signal tape player 10 is driven when the number has not been reached.

In the third embodiment shown in FIG. 4, a timer 14 is used in place of the input frequency integrator 11. That is, when the output of the number comparator 5 is turned on, the timer 14 operates and at the same time, an output is generated at one output terminal 15 of the timer and the therapeutic audio tape player 9 is driven. timer 1
When the preset timer time elapses, the output from one output end 15 of the timer disappears and the tape player 9 for therapeutic audio stops, and at the same time, an output is generated from the other output end 16 of the timer and the tape player 1 for deepening signal.
0 drives.

Timer 1 when the aforementioned timer time has elapsed.
If the input signal No. 4 is on, the set timer time is further added to the previous timer time.

In the second and third embodiments, the frequency of driving and stopping of the therapeutic sound tape player 9 and the deepening signal tape player 10, which are driven alternately, is reduced, so that the therapeutic sound and the deepening signal are continuous without being broken up. It is designed so that it can be effectively generated and administered to patients.

Although a tape player is used as a specific example of the stimulation device 8, sound or voice may be obtained by using a laser disc player, a compact disc player, a sound generator consisting of a sound synthesis unit, an oscillator, etc. in place of the tape player. good. Also, a deepening signal tape player 1 that generates sound or voice.
0 may be replaced with a light emitter that generates light, a vibrator that generates vibration, or the like, or a sound generator, a light emitter, and a vibrator may be used in addition to the deepening signal tape player 10.

Effects of the invention The present invention includes a frequency detector that detects the number of occurrences of alpha waves in the detected brain waves, and compares a set number of times with the output of said number detector, and if the output exceeds the set number of times, one output terminal A frequency comparator is provided to generate an output at the other output end when the output is not exceeded. With conventional devices, it was inaccurate to determine the amount of alpha waves generated, but with the configuration of the present invention, the amount of alpha waves generated can be determined by determining the number of times alpha waves generated from the head appear. It can be determined accurately. According to the results of this discrimination, when the number of occurrences of alpha waves is high, the therapeutic sound tape player is driven to let the patient hear the therapeutic sound, and when the number of occurrences of alpha waves is small, the deepening signal tape player is driven to generate alpha waves. Since it provides a signal such as a sound to promote the patient, it has the effect of automatically introducing the patient into an altered state of consciousness and effectively treating psychosomatic disorders and the like.

In addition, the output signal of the reference number setter and the output signal of the number detector are compared with the number comparator, and depending on the output of the number comparator, one of the two tape players, the treatment audio tape player and the deepening signal tape player, is selected. This is a configuration in which one player is driven. According to this configuration, it is also possible to generate an output only at one output terminal of the number comparator and drive only the therapeutic audio tape player by setting the reference number setting device. Furthermore, by using the input count integrator and timer shown in the second and third embodiments, it is possible to effectively drive the tape players by preventing frequent drive switching between the two tape players.

In other words, even if the patient's consciousness is in an altered state suitable for treatment, and the number of alpha waves that appear during treatment is extremely low, the drive of the tape player will not be switched and the tape player will not be used for therapeutic audio. The tape player can continue to be driven and treatment can be continued. This prevents the treatment audio tape player from stopping during treatment and interrupting the treatment, making it possible to effectively perform treatment in a state of altered consciousness.
