Hereinafter, a first embodiment of the present invention will be described with reference to the drawings.

(1) Configuration of hair restorer introduction device 1:
FIG. 1: shows the perspective view which looked at the hair restoring agent introduction apparatus 1 which concerns on this embodiment (1st Embodiment) from the upper front side. The hair restorer introduction apparatus 1 according to the present embodiment introduces a hair restorer (including a hair nourishing agent, a hair growth agent, and a chemical solution containing them) from the scalp using an electroporation method. As shown in FIG. 1, the apparatus main body 2, a pulse application unit 3 (described later) that is built in the apparatus main body 2 and can generate an electric pulse, and is electrically connected to the pulse application unit 3, An electrode 41 to which an electric pulse generated by the pulse applying unit 3 is applied is provided as a basic configuration. In FIG. 1, a table 23 on which the brush-like electrode main body 4 having the electrode 41 at the distal end portion 40 is mounted and fixed is mounted.

  The apparatus main body 2 constituting the hair growth agent introducing apparatus 1 according to the present embodiment includes an exterior case 21 that is a substantially rectangular casing with a panel-like operation unit 22 disposed on the front surface, and a pulse application (not shown) inside. The part 3 is disposed. The operation unit 22 is electrically connected to the pulse application unit 3 disposed inside the apparatus main body 2. In the present embodiment, for example, the pulse generation time, the pulse voltage level, and the pulse generation ON / OFF (ON / OFF), voltage level, vibration level by the electric motor 42 (described later) built in the brush-like electrode body 4, and start / stop of pulse generation can be adjusted.

  An electrode jack 26 is disposed below the operation unit 22 of the apparatus main body 2. The electrode jack 26 is electrically connected to a pulse applying unit 3 (not shown) built in the apparatus body 2 by inserting an electrode plug 431 provided at the tip of a connection cord 43 extending from the electrode body 4. It will be. A main power switch (not shown) for turning on / off the main power is disposed on the back of the apparatus main body 2. Further, the hair growth agent introducing device 1 of the present embodiment is supplied with power by inserting a power plug provided at one end of a power cord (not shown) extending from the device body 2 into an outlet (not shown).

(2) Configuration of electrode body 4:
FIG. 2 is a side view of the electrode main body 4 constituting the hair growth agent introducing device 1, and FIG. 3 is a sectional view of FIG. As shown in FIGS. 2 and 3, the electrode body 4 of the present embodiment is formed in a brush shape, and a tip portion 40 in which the electrode 41 is disposed in a comb shape, and a user at the time of use. It is comprised from the trunk | drum 44 used as the part grasped.

  The distal end portion 40 on which the electrode 41 is disposed is connected and integrated through a body portion 44 of the electrode body 4 and a rubber-made circumferential cushion portion 45. Further, since the distal end portion 40 is movable with respect to the torso portion 44, the distal end portion 40 on which the electrode 41 is disposed can move up and down and left and right according to the shape of the head. The electric pulse is smoothly applied.

  4A is a perspective view showing the tip 40 of the electrode body 4, FIG. 4B is a plan view showing the tip 40 of the electrode body 4 showing the arrangement of the electrodes 41, and FIG. 5 is a partially enlarged view around the electrode 41. (In FIG. 2, FIG. 3 and FIG. 4A, since the number of the electrodes 41 and the like is large, all the electrodes 41 and the like are not denoted by reference numerals 41, 411, and 462). As shown in FIG. 4A and the like, nine electrodes 41 corresponding to the comb teeth of the brush-shaped electrode body 4 are formed so that the electrode tip portion 411 of the electrode 41 is exposed from the tip of the comb-shaped insulating portion 462. The electrode 41 is erected on the tip 40 of the electrode body 4. As shown in FIG. 5, the electrode 41 is a substantially T-shaped rod-like member in cross-sectional view, which includes an electrode tip portion 411 and an electrode body portion 412, and a synthetic resin constituting the tip portion 40 of the electrode body 4. The comb-tooth portion 46 is a member made up of a base 461 and a cylindrical insulating portion 462 that is erected on the base 461 and into which the electrode body portion 412 is inserted. In the present embodiment, at the distal end portion 40 of the electrode body 4, the electrode body portion 412 of the electrode 41 is inserted into the insulating portion 462 of the comb tooth portion 46 formed in a comb tooth shape, The part 411 is exposed by the insulating part 462 so that it can contact the scalp. Thus, by exposing only the electrode tip 411 of the electrode 41 and insulating the electrode body 412 by the insulating portion 462, interference between the adjacent electrodes 41 can be prevented.

  Any one of the electrodes 41 is configured as a hot electrode (element) and a ground electrode (conductor). For example, the electrode 41 hatched in FIG. 4B is a hot electrode, and the other electrodes 41 are formed. It may be a ground electrode. When the hot electrode and the ground electrode come into contact with the scalp to which the hair-restoring agent has been applied in advance, an electric pulse is applied to the scalp and electroporation is performed. Further, a lead wire (not shown) extending from the hot electrode and a lead wire (not shown) extending from the ground electrode are electrically connected to a pulse applying unit 3 described later.

  The electrode 41 of the present embodiment shown in FIG. 4B has one electrode 41 (electrode 41 shown by a double circle in FIG. 4B) arranged in the center in plan view and eight electrodes arranged around it. Electrode 41 (an electrode other than the electrode 41 shown by a double circle in FIG. 4B), but the length of the electrode 41 arranged on the inner side (center) in plan view is the electrode arranged around the electrode 41 It is formed to be shorter than 41 length. Thus, since the length of the electrode 41 becomes shorter as it goes inward (center), the electrode 41 (electrode tip 411) is more likely to be in close contact with the scalp, so that an electric pulse is applied to the scalp. Will be performed smoothly. For example, the difference in length of the electrode 41 is preferably about 0.5 to 1.5 mm, and more preferably about 0.5 to 1.0 mm.

  The distance between the electrodes 41 may be determined in consideration of the size of the electrode body 4, the strength of the electric field to be loaded, the voltage height, the burden on the user, and the like. If the distance is too wide, the electrode 41 may not function. On the other hand, if the distance is too narrow, the electrodes 41 may interfere with each other. Therefore, the distance is preferably about 7 to 15 mm. The outer diameter of the electrode 41 is preferably about 3 to 10 mm, for example, and the length appearing outside the electrode 41 is preferably about 3 to 10 mm, for example.

  Conventionally known inorganic materials such as metals, carbon, and ceramics can be used as the material constituting the electrode 41, but an inorganic material that easily causes ionization (eg, silver) is used as the material constituting the electrode 41. Then, since the pH of the scalp that comes into contact may be changed and a side effect may be caused, it is preferable to use a material that does not easily cause ionization as the material constituting the electrode 41. Specifically, it is preferable to use stainless steel, platinum (platinum) or the like, and it is particularly preferable to use stainless steel.

  In addition, the electrode main body 4 which comprises the hair restorer introduction apparatus 1 of this embodiment incorporates the electric motor 42 as shown in above-mentioned FIG. The rotating shaft 421 of the electric motor 42 is connected to the eccentric element 422 so that eccentric movement can be performed. Then, the eccentric motion of the electric motor 42 is transmitted to the distal end portion 40 of the electrode body 4, and the periphery of the electrode 41 at the distal end portion 40 vibrates. The physical vibration gives a massage effect or relaxation effect to the scalp, and by using both electroporation for generating an electric pulse from the electrode 41 and physical vibration by the electric motor 42, hair growth from the scalp is performed. The absorption effect of the agent can be further increased. The frequency (frequency) of the electric motor 42 is preferably about 100 to 200 Hz, for example.

FIG. 6 is a schematic diagram illustrating an example of a circuit of the pulse applying unit 3, and FIG. 7 is a block diagram relating to the system of the pulse applying unit 3 constituting the hair restorer introducing device 1. In FIG. 6, the circuit related to the electric motor 42 is omitted, and only main parts or members are denoted by reference numerals.

  As shown in FIGS. 6 and 7, the transformer 31 constituting the pulse applying unit 3 of the present embodiment includes a first primary winding 311a and a second primary winding 311b that receive a rectangular pulse, and an electric pulse. A transformer 311 comprising a secondary winding 311c for generating The first primary winding 311a and the second primary winding 311b are driven by the transistor 313 (the first transistor 313a and the second transistor 313b) connected together, and in the present embodiment, the first primary winding 311a and the second primary winding 311b As shown in FIG. 6, the current flowing through the winding 311a and the second primary winding 311b is in the reverse direction (the first primary winding 311a is in the direction of the solid arrow, and the second primary winding 311b is in the direction of the dotted arrow. ), And the polarity of the output is reversed. The secondary winding 311 c applies an electrical pulse to the electrode 41 via the resistor 314, the capacitor 315, and the diode 316. Note that the voltage supplied from the power supply 32 is amplified by an operational amplifier 331 provided in the amplification unit 33.

  FIG. 8 is a schematic diagram illustrating an example of a rectangular wave pulse train input to the first primary winding 311a. FIG. 9 is a schematic diagram showing an example of a rectangular wave pulse train input to the second primary winding 311b. As shown in FIGS. 8 and 9, in the pulse applying unit 3 of the present embodiment, the rectangular wave pulse train input to the first primary winding 311a and the second primary winding 311b are input. The rectangular wave pulse train has a slightly different phase. As described above, the first primary winding 311a is driven by the first transistor 313a and the second primary winding 311b is driven by the second transistor 313b, but the transistors 313 (313a, 313b) are turned on / off. Therefore, the electric pulse generated from the secondary winding 311c corresponding to the rectangular wave pulse train input to the first primary winding 311a and the second primary winding 311b is as shown in FIG. In addition, an electric pulse generated from the secondary winding 311c and applied to the scalp from the electrode 41 is a resistor 341 and a capacitor 342 as shown in FIGS. Is applied to the scalp as a burst (burst wave) formed by inputting the rectangular wave.

  FIG. 10 is a schematic diagram showing an example of individual electric pulses generated from the transformer 311 (secondary winding 311c). FIG. 11 is a schematic view showing an example of a burst of electric pulses generated from the secondary winding 311c and applied to the electrode 41, and FIG. 12 is a partially enlarged view of FIG. As described above, in the present embodiment, the electric pulse generated from the transformer 311 (secondary winding 311c) is a rectangular wave in which positive and negative are continuous.

As shown in FIG. 11 and FIG. 12, the burst of electric pulses that are electric pulses applied from the electrode 41 is an applied voltage composed of an assembly of individual electric pulses shown in FIG. It has a part P _ON (on part) and a pause part P _OFF (off part). Further, the waveform of the pressure conductive portion P _ON of such bursts, has a rising portion P _U of the voltage rises in a curved shape, the trailing portion P _D that the voltage drops to the curve. By making the rise and fall of the voltage curve, the electric pulse acts gently on the scalp, and the stimulation to the scalp can be suppressed. In addition, the voltage is continuously applied by making the rise and fall of the voltage curve, so that the hair growth agent introduction path is formed and maintained, and the introduced hair growth agent is electrophoresed. Is carried out efficiently, and the effect of introducing the hair restorer is also improved. Incidentally, in the 11 and 12, the rising portion P _U rises in a curved shape so as to draw a turret-shaped curve, the fall portion P _D is rotated 180 ° the rising portion P _U, A so-called exponential decrement curve is drawn to show a descending curve.

Further, as shown in FIGS. 11 and 12, the waveform of the pressure conductive portion P _ON burst in this embodiment, between the rising portion P _U and the falling portion P _D, stabilization part P where the voltage becomes constant _The aspect which has _S is shown. During the falling portion P _D that is rising portion P _U and the voltage which the voltage rises in curved descends curved, by providing a stable unit P _S where the voltage becomes constant, the applied voltage is more continuously As a result, the introduction of the hair restorer will be carried out efficiently.

10 through electrical pulses each 1 period _{T S} shown in FIG. 12, it is preferable that the 0.1~1.0ms (1~10kHz as frequency) degree. Also, one period _{T B} of the burst, it is preferable that the 10~50ms (0.02~0.1kHz as frequency) degree.

In the burst of electric pulses in FIGS. 11 and 12, the charging time T _ON in the burst is preferably 9 to 39 ms, and the pause time T _OFF is preferably 1 to 11 ms. Further, in the case of providing the stable portion _{P S} to the pressure conductive portion _{P ON,} the rising portion _{P U} of the voltage rises to the curved 3～13Ms, a stable portion _{P S} 3~13ms, voltage is curved The falling part PD that descends may be about ₃ to 13 ms. Incidentally, FIGS. 11 and 12, 0.5 ms electrical pulses each one period _{T S} (2kHz), 20ms one period _{T B} of the burst (0.05kHz (50Hz)), 15ms pressurized charging time _{T ON,} downtime _{T OFF} to 5ms, of pressurized conductive portion _{P ON,} shows an embodiment in which a 5ms rising portion _{P U,} a stable portion _{P S} and the falling portion _{P D,} respectively.

  The shape of the burst of electric pulses is determined by a resistor 341 and a capacitor 342 provided in the waveform forming unit 34 shown in FIGS. The resistance value R of the resistor 341 is preferably R = 10 k to 1 MΩ, for example, and the capacitance value C of the capacitor 342 is preferably C = 1 to 100 nF, for example. The relationship between the resistance value R of the resistor 341 and the product (R · C) of the capacitance C of the capacitor 342 may be about R · C = 0.0005 to 0.002.

11 and 12 show the shape of the burst when the resistance value R of the resistor 341 is 100 kΩ and the capacitance C of the capacitor 342 is 10 nF. If the capacitance value of the capacitor 342 is larger than the above case, the burst of rising portion P _U and the falling portion P _D becomes gentler than 11 mag, the smaller the capacitance value of the capacitor 342, the rising portion P _U and the falling portion P _D of the bursts is sharper than 11 mag. Similarly, if the large resistance value of the resistor 341 than in the rising portion P _U and the falling portion P _D of the burst becomes gentler than 11 mag, if the resistance value of the resistor 341 is small, the rising portion of the burst P _U and the falling portion _{P D} becomes sharper than 11 mag.

  In addition, the voltage (pulse voltage) of the electric pulse applied to the scalp from the electrode 41 for applying the electroporation method may be determined in consideration of the stimulation and the burden on the user. It may be in the range of ˜50V, and it is preferably 5˜35V. If the pulse voltage is within the range, there is less irritation and burden on the scalp, and the introduction of the hair-restoring agent into the scalp using electroporation is more safely performed.

  The voltage of the electric pulse is amplified by the amplifying unit 33 with respect to the voltage supplied from the power supply 32. However, the electric pulse is applied to the scalp as an electric pulse in a state where the voltage is too high. Therefore, it is preferable to apply to the scalp with the voltage adjusted. In the hair restorer introduction device 1 of the present embodiment, the voltage is adjusted to about 0.1 to 50 V (preferably 5 to 35 V) by the control unit 35. The control unit 35 includes control means such as a microcomputer (not shown), and adjusts the magnitude of the voltage amplified by the amplification unit 33 according to a program or the like input in advance. The control unit 35 is also electrically connected to the operation unit 22 described above, and transmits information input from the operation unit 22 by the user to each of the electrically connected units.
