Preferred form for carrying out the invention

  Hereinafter, although the preferable form for implementation of this invention is demonstrated in detail, the scope of the present invention is not limited to these forms.

  A trigeminal nerve perceptual branch stimulating apparatus will be described with reference to FIG. 1 which is a schematic diagram showing an embodiment of the present invention.

  The trigeminal nerve perceptual branch stimulating device 1 has a lead wire extending from a power supply circuit 14 for flowing a direct current, which is built in a circuit box 20 large enough to fit in a breast pocket, and has a metal electrode 11a. 11b. The electrodes 11a and 11b are respectively exposed from the center of the disposable electrode pads 12a and 12b covered with the polymer gel for sticking and sticking to the heel.

  FIG. 2 shows a schematic block circuit diagram of the circuit box 20. A sensor 13 for detecting the biological movement is connected to the circuit box 20 and connected to the biological movement detection circuit 15 therein. The biological movement detection circuit 15 is connected to the timer 16 and the power supply circuit 14. The biological movement detection circuit 15 is connected in the order of the drowsiness discrimination circuit 17, the filter circuit 18, and the switch circuit 19. The switch circuit 19 is connected to the electrodes 11a and 11b through lead wires.

  The biodynamic sensor 13 is a temperature sensor that detects the temperature of the hand such as the temperature of the tip of the thumb. The temperature sensor is a thermal infrared sensor made of, for example, a metal oxide or a thermistor that is a semiconductor, and measures the temperature of the hand by utilizing the change in electrical resistance according to the temperature. The timer 16 is a time switch for operating the biological movement detection circuit 15 such as a temperature detection circuit every predetermined time. The biological movement detection circuit 15 is an A / D converter that performs analog-digital conversion on the output of the thermistor electrical resistance of the sensor 13. The drowsiness discrimination circuit 17 previously detected from both memories, a memory for sequentially storing hand temperature values obtained by analog-to-digital conversion, a memory for storing hand temperatures during normal times without drowsiness. A reader that reads both the latest hand temperature and normal hand temperature values, a subtraction circuit that subtracts the latest hand temperature value from the normal hand temperature value, and the obtained subtraction result value And a digital comparator that compares the magnitude of a preset threshold as a hand temperature in a drowsiness state that is slightly higher than normal, and a switching element that sends a current conduction signal when the hand temperature exceeds the threshold by the comparison It consists of. The filter circuit 18 is a filter that removes the current conduction signal when the change in the temperature of the hand is temporarily within the fluctuation range of the day and the hand is rubbed. The switch circuit 19 allows a current to flow from the power storage element such as a capacitor or a power source to the electrodes 11a and 11b in accordance with the current conduction signal.

  The trigeminal nerve proper sensory branch stimulation apparatus 1 is used as follows.

  First, as shown in FIG. 3, the circuit box 20 of the trigeminal intrinsic sensory branch stimulator 1 in which the negative electrode 11a / positive electrode 11b and the biodynamic sensor 13 are connected is inserted into the breast pocket. The negative electrode 11a is placed on the center of the face, which is the peripheral side of the trigeminal first branch proper sensory branch 6a (see FIG. 1), and the positive electrode 11b is placed on the left eyebrow upper edge, for example, near the lower edge of the left eyebrow. Affix to the left corner of the left eye, which is the central side. The lead wires extending from the electrodes 11a and 11b are hooked on the earlobe and connected to the circuit box 20 with a margin. On the other hand, the left thumb is inserted into a ring-shaped holder that supports the temperature sensor of the thermistor which is the biodynamic sensor 13. The lead wire extending from the biodynamic sensor 13 is connected to the circuit box 20 with a margin so as not to be wound around the arm.

  The current corresponding to the thermistor electric resistance value of the biodynamic sensor 13 is measured at a predetermined time according to the instruction of the timer 16, and the analog signal is output to the biodynamic detection circuit 15, and the temperature of the hand, which is the tip temperature of the thumb. Is detected.

  The temperature of the hand is generally somewhat higher in sleepiness than normal, when it is not sleepy. Although there are some fluctuation ranges depending on the temperature, the presence or absence of exercise, individual differences, etc., the fluctuation range of hand temperature during normal times is substantially the same.

  In accordance with this, the threshold value of the sleepiness discrimination circuit 17 is set to a value corresponding to, for example, 0.1 ° C. When the temperature of the hand is detected by the biological movement detection circuit 15, the drowsiness discrimination circuit 17 operates as follows. First, the temperature of this hand is sequentially stored in the memory. The difference between the detected hand temperature value and the normal hand temperature value read from the memory storing the normal hand temperature is calculated. This calculation may be a digital calculation, or a current proportional to the value may be differentially input to the operational amplifier. If the difference exceeds the threshold value, a current conduction signal is supplied. In this way, the sleepiness discrimination circuit 17 discriminates that the sleepiness state is caused by the temperature rise of the hand. When a predetermined time has elapsed, the next instruction is issued from the timer 16, and the temperature of the hand is similarly detected.

  When the change in the hand temperature is within the range of the fluctuation range at the normal time, the current conduction signal is not supplied. On the other hand, when this current conduction signal flows and passes through the filter circuit 18, the switch circuit 19 that receives the current causes a current to flow for an instant or several minutes, preferably several tens of seconds.

  Then, as shown in FIG. 1, electricity flows to the upper left eyelid 2 through the electrodes 11a and 11b. Then, the trigeminal first branch intrinsic sensory branch 6a running across the upper end of the upper eyelid 2 is stimulated by the current.

  The stimulated trigeminal first branch proper sensory branch 6a contracts on the peripheral side, and as a result of contracting the Muller muscle 4 extending from the levator levator muscle 7 pulling up the upper left eyelid 2, it is connected to the Muller muscle 4. Pull the plate 3 to open the eyes.

  In addition, the stimulated trigeminal first branch intrinsic sensory branch 6a is the central side 6b, penetrates the upper orbital cleft 8 of the bone to the brain, and stimulates the blue patch nucleus through the trigeminal mesencephalic nucleus in the brain. Or stimulate the facial nucleus.

  These blue nuclei endocrine from the thalamus to stimulate the prefrontal cortex, stimulate the amygdala to cause emotions, awaken the whole body, increase tension, improve attention, Increases blood flow, promotes muscle contraction, and promotes sweating in the palm of the hand. In addition, the blue nuclei stimulate the hippocampus that controls memory to improve memory, stimulate the cerebellar γ pathway to cause muscle tone and ipsilateral generalized involuntary contraction, via the hypothalamus Tension of the sympathetic nerve, contraction of the Muller muscle 4 and further contraction of the muscles related to the iris that regulates the size of the pupil, causing mydriasis to focus far away, sleep / wake rhythm Or suppress the raphe nucleus involved in the.

  This facial nerve nuclei contracts the frontal occipital muscles and raises the eyebrows to open the eyes, stimulates the oculomotor nucleus through the frontal eye field, optionally contracts the levator levator muscle 7, and The eyes are opened by contracting the aponeurosis 5 adhering to the skin and the Muller muscles 4 on the back side and connected to the base plate 3.

  In addition, the stimulated trigeminal first branch intrinsic sensory branch 6a directly stimulates the oculomotor nucleus and involuntarily contracts the levator ani muscle 7, thereby opening the eyes as described above.

  By these actions, the person who uses the trigeminal nerve intrinsic sensory branch stimulator 1 becomes awakened or excited, awakens from drowsiness, improves thinking ability, memory ability and concentration ability, and maintains the state for a while.

  In addition, although the mode which discriminate | determines that it is a drowsiness state when the change of the biodynamics exceeded the previously memorized range of the dynamics of the biological dynamics, You may memorize | store sequentially in real time and discriminate | determine that it is a drowsiness state when the change of a biodynamic exceeds the fluctuation range.

  An example of a trigeminal nerve perceptual branch stimulator that stimulates the trigeminal first branch intrinsic sensory branch from the top of the eyelid with an electrode has been shown, but the trigeminal nerve first branch intrinsic sensory branch is stimulated directly by opening the eyelid. May be. Electrodes may be implanted in the heel to stimulate the trigeminal first branch intrinsic sensory branch directly.

  The current passed through the electrode is not particularly limited as long as it promotes eye opening and increases palm perspiration and arousal level. For example, 1 to 50 mA is preferable, and in the above range, the current is constant DC. It may be a direct current pulse current. It is preferable that the current flow time is, for example, 0.1 milliseconds to continuous. The current may be a pulse current discharged at a repetition frequency of 1 to 100 Hz by a switching element (not shown) controlled to be turned on and off in the switch circuit.

  As the temperature sensor, a temperature sensor such as an infrared detection sensor, a thermocouple, or a resistance temperature detector may be used instead of the thermistor. As an example of the body temperature, a temperature sensor detects a change in biodynamics based on the temperature of the hand, particularly the tip of the thumb. However, the temperature at other parts such as the side or the eardrum may be measured.

As the biological movement detection sensor, a commercially available drowsiness detection device may be used.
Instead of detecting the body temperature with a temperature sensor, peripheral blood flow that increases in the sleepy state or cerebral blood flow that decreases in the sleepy state may be detected with a blood flow meter such as a near infrared sensor. You may detect the blood pressure and pulse which fall in a sleepiness state with a pressure gauge like a pressure sensor. An electroencephalogram waveform, for example, a wakeful wave appearing in a drowsiness state may be detected by an electrode for potential measurement, or an electrocardiogram waveform or a myoelectric waveform may be detected by an electrode for potential measurement. Respiratory rate per unit time is detected by a counter using a CCD (solid-state imaging device) camera to capture and process images with a solid-state image sensor (CCD) camera, and to measure the respiratory rate per unit time. Also good. Sweating gradually increasing in a drowsiness state may be detected with an infrared moisture meter. The movement of the pupil and the size of the pupil, which are emptied in the sleepy state, may be captured by a CCD camera and detected by image processing of the line of sight and eye movement. The interval between blinks that become longer in the sleepy state may be captured by a CCD (solid-state imaging device) camera and detected by image processing of vertical movement. A tilt or a posture shift that tilts the head or upper body in a drowsiness state may be detected by an inclinometer or a weight scale. An upper body motion such as rowing a boat in a drowsiness state may be captured by a CCD camera and detected by image processing of the motion or detected by an inclinometer. It is possible to detect momentary convulsions in the drowsiness state with an electrode for measuring the potential of myoelectricity, or to take a picture with a CCD camera and detect the movement. It is also possible to detect an unnatural shaking of a hand gripping an object with an inclinometer attached to the steering wheel. It may be like a polysomnograph combining a plurality of them.

  As shown in FIG. 4, the trigeminal nerve intrinsic sensory branch stimulating device 1 may not have a biological movement detection sensor, and may be a device that voluntarily switches on and allows a current to flow. For example, when drowsiness is caused while driving a car, the electrodes 11a and 11b are spontaneously applied to the vicinity of the lower edge of the left eyebrows to switch on, and when the current is applied or forced to awaken, The electrodes 11a and 11b are applied to the vicinity of the lower edge of the left eyebrow and a current is passed.

  Further, the trigeminal nerve intrinsic sensory branch stimulating device 1 may be one that stimulates with a coil 21 that generates a magnetic field, as shown in FIG. 5, instead of the electrodes 11a and 11b. The coil 21 is preferably exposed from the center of the disposable coil pad 22 coated with a polymer gel. The trigeminal nerve proper sensory branch stimulation apparatus 1 may have the above-described biodynamic sensor. As shown in FIG. 5, it may have a single coil 21 having a diameter of about 1 to 3 cm, or may have a plurality of, for example, two coils facing inward or on the same plane.

  The coil 21 is arranged in place of the electrodes 11a and 11b in the block diagram shown in FIG.

  The trigeminal intrinsic sensory branch stimulator 1 having a single coil is used as follows.

  The coil 21 is affixed on the eyelid at the upper edge of the left orbit, for example, near the lower edge of the left eyebrow. Similarly to the trigeminal nerve perceptual branch stimulating device 1 having the electrode, when a current conduction signal flows from the drowsiness discrimination circuit 17, a current is passed from the storage element to the coil 21 by the switch circuit 19 receiving the current conduction signal (FIG. 2). Then, the coil 21 generates a magnetic field as shown by a two-dot broken line in FIG. This magnetic field induces an eddy current in the vicinity of the trigeminal first branch proper perception branch 6a (see FIG. 1) beyond the eyelid. The trigeminal first branch proper sensory branch 6a is stimulated by the current. As a result, similar to the above, various effects by stimulation of the blue spot nucleus and the like are exhibited.

  The magnetic field having the above-mentioned strength is not particularly limited as long as it promotes cleavage and increases palm perspiration and arousal level. For example, 1 mT to 3 T is preferable. In order to generate such a magnetic field, it is preferable that the current flow time is, for example, 0.1 milliseconds to continuous. Although an example in which a magnetic field is generated once has been shown, a pulsed magnetic field may be generated by causing a direct-current pulse current generated by a power supply circuit or a pulse generation switching control circuit (not shown) to flow through the coil. The current may be a pulsed current that is discharged by the switching circuit at a repetition frequency of 1 to 100 Hz.

  The trigeminal intrinsic sensory branch stimulating device 1 having the same configuration except that it has a plurality of, for example, two coils is used as follows. When a plurality of, for example, two coils containing a coil and simultaneously applying pulse currents in opposite directions to the rings that face each other while tilting each other, eddy currents are induced while being strengthened by the magnetic field generated at their center, The trigeminal first branch intrinsic sensory branch 6a is stimulated more strongly.

  The current passed through the coil may be direct current or alternating current.

  Stimulation using a trigeminal nerve proper sensory branch stimulation device having a coil is more preferable because pain can be felt less than stimulation using a device having an electrode.

  Although an example in which an electric current is supplied to an electrode or a coil in the case of a drowsiness state exceeding the fluctuation range of the biodynamics has been shown, a switch circuit that supplies an electric current at regular time intervals or every predetermined time may be connected by a timer.

  Since these trigeminal nerve perceptual branch stimulating devices 1 exhibit awakening action similar to drugs such as stimulants, they can be used not only to wake you up while driving or studying, Used to improve memory, stimulate the brain to improve the symptoms of dementia patients, increase concentration when distraction, exercise, competition, work, discussion or It can also be used to increase tension during a battle, to elevate it, or to restore vision when it drops.

  In addition, the trigeminal nerve perceptual branch stimulating device 1 awakens and relieves the patient during surgery, increases cerebral blood flow, and tensions the trigeminal first branch proper perception branch to prevent damage to the trigeminal first branch proper perception branch. Used.

  Furthermore, the trigeminal nerve proper sensory branch stimulating device 1 can also be used for the correction treatment of the stimulant regular patient.

  An example in which the trigeminal nerve proper sensory branch stimulation apparatus 1 according to the present invention is made as a trial and its effectiveness is examined is shown below.

  The prototype trigeminal nerve perceptual branch stimulation device 1 does not have a biological movement detection sensor, and is connected to a DC power source 14 in order, a resistor and a thyristor, and connected to electrodes 11a and 11b via a switch circuit. is there. The electrodes 11a and 11b are exposed from the electrode pads 12a and 12b covered with the polymer gel. On the right or left upper orbital upper eyelid near the lower edge of the eyebrows, the negative electrode 11a is located at the center of the face, which is the peripheral side of the trigeminal first branch intrinsic sensory branch 6a, and the positive electrode 11b is located at the central side Attached to the outer corner of the eye, about 2 cm apart.

  A current of 20 mA was passed through the electrodes 11a and 11b for 30 seconds or 60 seconds.

  FIG. 6 shows changes in relative values of the prefrontal α wave, β wave, and θ wave over time when a current is passed through the trigeminal nerve intrinsic sensory stimulator while measuring brain waves. As is clear from FIG. 6, after the current was passed, the brain wave of a clear and clear β wave was enhanced, and it became wakeful, and it was shown that the wakefulness was maintained for a while even if the stimulation was interrupted. .

  FIG. 7 shows changes over time in the amount of sweating between the right hand and the left hand when a current is passed through the trigeminal nerve perceptual branch stimulator while measuring the amount of sweating from the right hand and the left hand. As is clear from FIG. 7, after the current was passed, clear perspiration was continuously observed, and the tension state was maintained for a long time.

  Changes in cerebral blood flow in the prefrontal cortex when current was passed through the trigeminal intrinsic sensory branch stimulator while measuring cerebral blood flow using a near-infrared light measuring device, oxygen saturation, total hemoglobin (Hb) value, FIG. 8 shows changes over time measured using the oxidized Hb value and the reduced Hb value as indices. The figure shows relative values when the initial value of oxidized Hb is 35. As is clear from the figure, when an electric current was passed, the blood flow continued to increase, indicating that it was in an excited state.

  Similar to the case where current is passed from the electrode, the same result can be obtained when a magnetic field is generated by the coil. The same result can be obtained even with a body movement detection sensor.

  The trigeminal nerve perceptual branch stimulator of the present invention prevents asleep during driving or studying, arouses, excites, improves symptoms of demented patients, or focuses on a patient who is difficult to focus on far away It is used to relieve pain and to correct stimulant patients.
