Description

[Detailed Description of the Invention] [Object of the Invention] (Industrial Application Field) The present invention utilizes a high frequency electronic circuit. The present invention relates to a hair growth device that capacitively transmits current to the human body.

(Prior art) High-frequency energy is well known to improve blood circulation in the human body, increase cytoplasmic secretion, and activate the circulation of circulating fluid in the body. The method of supplying (hereinafter referred to as capacitive transfer system - CTS) is known as a medical device or a beauty device. This method utilizes the heat generated by the rotational motion of electric dipoles present in the dielectric itself within an alternating electric field.

It is an efficient method because it can concentrate heat energy without irritating the skin. Other known devices that improve blood circulation include devices that utilize ultrasonic vibrations and devices that utilize acupuncture.

(Problem to be solved by the invention) However, hair is different from other skin, and when excessive energy is applied, the hair root itself is damaged and heat is applied, which has the opposite effect and causes the cell tissue of the hair root to be damaged. This causes many problems, including the fact that even if thermal energy is applied to a large area of the skin at once, the heat is not evenly distributed and sufficient hair growth cannot be achieved.

The present invention has been made in view of the above circumstances.

The object of the present invention is to provide a hair growth device that uniformly applies appropriate energy to each hair without causing any danger to the human body, and an efficient method for using the device.

[Structure of the invention]

(Means for Solving the Problems) The present invention first relates to a hair growth device that utilizes a high frequency signal oscillated from an active electrode connected to a secondary winding of a high frequency transformer, and includes a high frequency main electronic circuit. , a circular conductor having an active electrode connected to the high-frequency main electronic circuit, and a neutral electrode connected to the high-frequency main electronic circuit, and the high-frequency main electronic circuit basically consists of: , an oscillation circuit that outputs to the transistor of the amplification stage, the amplification stage, a driver that receives the amplified signal of the transistor, a resonant circuit that receives the signal received by the driver, and a signal from the resonant circuit. In the hair growth device, the active electrode is connected to a secondary winding of the high-frequency transformer, and has a diameter of about 10 to 100 mm. It is disc-shaped, and a plastic thin film with a thickness of about 0.05 to 0.5 mm with a high dielectric constant or dielectric loss is formed on its surface, and the frequency of the signal output from the secondary winding is is characterized by being between 0.5 and 0.78 megahertz (MH2). The second method relates to its method of use, and is characterized by applying a highly conductive lotion to the skin that is in contact with the circular conductor and its surroundings to make the surroundings highly conductive.

(Function) After the high frequency main electronic circuit of the present invention transmits a signal from 9 oscillation circuits, it gradually increases the voltage to 0.5 to 0.78 MH at the output stage.
7 high frequency signals can be stably output, and the circular conductor can stably supply heat energy into the body.

Furthermore, by using the lotion, the affected area and its surroundings can always maintain a constant state of high conductivity during the operation of this hair growth device.

This high frequency signal can be efficiently supplied into the body as thermal energy.

Hair on the human body falls out due to lack of blood circulation and excess fat. That is, nine hair root tissues are destroyed.

The main cause of this seems to be that the base electrons in the cytoplasm of the hair root jump out due to an imbalance in the body, causing aging. Appropriate thermal energy can rejuvenate the cytoplasm by returning electrons to their original bases.

In addition, applying the lotion to bring the skin surface between the circular conductor's plastic thin film and the neutral electrode into a uniform state of high conductivity means that this thin film becomes a dielectric and the active electrode and the neutral electrode are separated. It means forming a capacitor as an electrode,
The heat generated by this dielectric material is transferred into the body as a heat flow. The resistance of this lotion is 2600Ω, while the resistance of the cream used in the conventional CTS device is .

It is 7000Ω.

The end result of using this hair growth device is to revive the 9 tissues and therefore hair will grow, which is 1.
As long as there are hair roots in areas where there has been no hair for the past 20 years, you will see results in about 3 weeks.

(Example 1) An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a schematic diagram of the main electronic circuit of the present invention. In the lower part of this diagram, the 100V AC received from the power supply is transferred to the transformer T.
3 and rectifiers RIC and R2C to form two DC power supplies, and serves as a power supply source for the oscillation stage of the upper high-frequency main electronic circuit and other main circuits.

The high frequency main electronic circuit includes an oscillation stage 2 consisting of an IC. The output signal of this oscillator stage is sent to an amplification stage. The amplification stage consists mainly of a transistor Tr1, with a minimum ohmic resistance from the collector of this transistor and a very high inductance or impedance for the highest voltage, and a signal sent to a driver 5 consisting mainly of a transistor Tr2. perform the necessary amplification. This driver sends a signal to the resonant circuit 6. This resonant circuit includes a radio frequency transformer T1 and is connected to the transistor Tr3 via this transformer. This transistor forms an amplifier with resistor RIO. This amplifier forms an output stage together with the high frequency transformer T2. The terminals 1.12 of the secondary winding of this high-frequency transformer are connected to an active electrode 21 and a neutral electrode 25, respectively. In addition,
In this circuit diagram, a capacitor C19 is inserted into terminal 1 of the secondary winding of the transformer T2.
This prevents direct conduction of high frequency current to the human body when the dielectric thin film on the active electrode is damaged.

FIG. 2 shows the structure of the circular conductor 20, in which the active electrode 2 of the main body has a disk shape with a diameter of 10 to 100 mm and is supported by a rod-shaped body. This active electrode is connected to the terminal 1 of the secondary winding of the high frequency transformer via the rod-shaped body, and this connection is covered with a bushing 24 that covers this terminal. This electrode is also covered with a thin plastic dielectric film 22 having a high dielectric constant and high corrosion resistance. This thin film 22 also partially covers the exposed rod-shaped body. This bushing and rod-shaped body are 9 gripping bodies 23
The grip body is mostly covered with an insulating material (not shown).

This electrode is made of a highly conductive material such as brass, but its surface is easily damaged by high-frequency current, so
It is protected by a plating such as " or Ni. Therefore, 1
Even if the surface is damaged, the electrode can be reused by simply repairing this protective plating.

(Embodiment 2) FIG. 3 shows a housing 30 that houses the actual circuit shown in FIG. 1.
The front of the casing includes a dial to adjust the strength of the output signal current and a socket to accept the plug for connecting the active and neutral electrodes to the circuit. Each of these plugs is connected to each electrode by a cord. The strength of the current is expressed by Equation 9: 1=2πfCV.

Here, f is the frequency, C is the electrode capacitance, and ■ is the voltage between the electrode and the skin. Based on this formula, the strength of the supplied current is adjusted.

To put it into action, first apply a highly conductive lotion to the skin and surrounding area. Next, the rod-shaped neutral electrode shown in FIG. 3 is held and the disk surface of the one-circle conductor is brought into contact with the target hair part. In this state, when a high frequency current of a predetermined intensity is supplied from the active electrode, a heat flow is generated within the body from this contact portion toward the neutral electrode (see FIG. 4).

At this time, a capacitor is constituted by the nine electrodes and the dielectric thin film between them. Since this lotion is applied, the surface is in a uniform and highly conductive state no matter what the skin condition is, and therefore a stable heat flow can be obtained. Furthermore, if the disk of the active electrode is small, sufficient thermal energy cannot be obtained, and furthermore, hair becomes entangled, making operation difficult. On the other hand, if it is large, the heat flow becomes unstable and stable treatment cannot be performed, so the size is limited to a diameter of 10 to 100 mm.

This hair growth device has no adverse effects on the human body.

The operating frequency is completely tolerated by the human body. The allowable amount of power for the human body is about 400 W, which is the same as the power of an electric scalpel. on the other hand.

The power required for this device is a maximum of 18 W, which is about 5% of the maximum allowable amount, so there is no danger. Also.

The maximum capacitance delivered using this electrode is 50 picofurads, which is the rated capacity for anti-irritation of the electrocautery (50 picofurads).
This is two orders of magnitude lower than 000 picofarads). The effects of this hair growth device will begin to appear in about three weeks when used for about 15 minutes once a day or every two days, and use can be completed in about six months to a year.

〔Effect of the invention〕

The hair growth device of the present invention, having the above-described configuration, can uniformly supply an appropriate amount of heat energy to the hair without any danger to the human body, so that a remarkable hair growth effect can be obtained. .
