Description

  The present invention relates to a hair follicle insertion probe, and is particularly suitable for application to adjusting the hair-growth function of hair root tissue.

Conventionally, in the field of cosmetic hair removal, a hair removal probe (also called a needle) is inserted into a hair follicle for the purpose of removing unwanted hair from the viewpoint of beauty, and this is used as an electrode for high frequency in the hair follicle. By applying a current and / or a direct current, heat energy is converted into the hair root tissue to cause heat coagulation of the protein in the hair root tissue, and / or NaOH is generated by electrolyzing NaCl in the hair follicle. Cosmetic hair removal technology that destroys the hair root tissue (hair papilla) by the strong alkali action is used (see Patent Document 1).
JP-A-6-7218

  Originally, hair growth inhibitors and hair growth agents are generally of a lotion type, and the hair growth inhibitor is applied to the arms and legs where hair growth is to be suppressed. The effect is promoted by penetrating the hair root tissue. However, the sebum (oil) on the surface of the skin and scalp interferes with its penetration, and the effect that the liquid agent has is not fully exhibited.

  By the way, this hair removal probe technique uses a hair follicle insertion type hair removal probe in order to provide conditions for causing the hair root tissue to be destroyed by electrical action. Supplying a hair-growth agent that activates the hair-growth function to the tissue (hair papilla), injecting a hair growth inhibitor or hair removal agent that suppresses hair growth into the hair follicle, or attaching it to the hair root tissue If it is possible, it can be applied not only to eliminating unwanted hair, but also to, for example, hair nourishment, hair growth, and hair removal.

  The present invention has been made in consideration of the above points. By injecting the liquid agent into the hair follicle or directly adhering to the hair root tissue, the liquid agent can be supplied to the hair root tissue so as to be more easily absorbed. An attempt is made to propose a hair follicle insertion probe.

In order to solve this problem, in the present invention, a hair follicle insertion portion 21B that is made of a conductive resin material and is inserted into the hair follicle 15 from the tip portion, and a tip portion of the hair follicle insertion portion 21B that is made of a conductive resin material. A boundary between the stepped portion 21C connected to the outer peripheral surface of the base side end portion extending from 21B1 in the root side direction and inclined so that the outer diameter becomes thicker toward the root side direction, and the hair follicle insertion portion 21B of the stepped portion 21C At the position, liquid agent guide ports 26A and 26B are provided to discharge the liquid agent so as to flow around the hair follicle insertion portion 21B, thereby collecting the liquid agent between the hair follicle 15 and the hair root portion 17.

According to the present invention, the liquid agent is discharged from the liquid agent guide port so that the liquid agent flows around the hair follicle insertion portion at the boundary position with the hair follicle insertion portion of the stepped portion provided at the root side end of the hair follicle insertion portion. Then, since the liquid agent is in a state of being accumulated between the hair follicles or the hair roots, the active ingredient of the liquid agent is present in a state in which it is easy to permeate. Or, the hair removal effect can be adjusted as necessary.

  Hereinafter, an embodiment of the invention will be described in detail with reference to the drawings.

(1) Overall Configuration In FIG. 1, 1 indicates a hair growth function adjusting device as a whole, and a power source 3 for ion infiltration is provided in the device main body 2.

  The ion infiltration power source 3 is connected to the counter electrode 4 held by the patient through one of the external connection terminals 2A and the other power output line S2 of the ion infiltration power source 3 through the external connection terminal 2A. Is connected via a cable 6 to the probe holder 5 held by the practitioner via the electrical connector portion of the external connection terminal 2B.

  The apparatus main body 2 is provided with a compressor 7, and the compressed air passes through the air connector portion of the external connection terminal 2B and is supplied to the liquid agent tank 9 via the compressed air pipe 8 connected to the air connector portion.

  The liquid agent tank 9 is a liquid agent (chemicals, cosmetics, and medical departments that cause a hair-growth effect or a hair-growth effect or a hair removal effect in the liquid agent pipe 10 connected to the probe holder 5 by compressed air supplied from the compressed air pipe 8. Send out).

  The practitioner operates the operation switch 12 each time with the hair follicle insertion probe 11 attached to the tip of the probe holder 5 inserted into the hair follicle 15 (FIG. 2) one by one from the subject's pore. Thus, when an operation command is given to the central processing unit (CPU) 13, the compressor 7 is driven to supply the liquid agent in the liquid agent tank 9 to the hair follicle insertion probe 11 through the liquid agent pipe 10, and ion permeation By applying the power output of the power supply 3 to the hair follicle insertion probe 11 via the cable 6, an ion permeation current can flow from the hair follicle insertion probe 11 toward the counter electrode 4. .

  In this state, as shown in FIG. 2, the hair follicle insertion probe 11 is inserted into the hair follicle 15 along the hair 16 from the pore, and the tip is positioned at the position of the hair root portion 17. Thus, when a direct current flows to the root tissue (hair papilla) of the hair root portion 17 through the liquid agent supplied to the hair follicle 15, the active ingredient of the liquid agent is permeated and absorbed into the hair root portion 17 by ion osmosis therapy.

  Thus, the active ingredient of the liquid agent supplied to the hair root portion 17 by the hair follicle insertion probe 11 can be easily permeated and absorbed by the hair root portion 17 by ion osmosis therapy, so that the hair growth effect or the hair growth inhibiting effect and the hair removal effect can be achieved. Can be adjusted as needed.

(2) First Embodiment In FIG. 3, reference numeral 21 denotes a hair follicle insertion probe according to the first embodiment of the present invention, which is used as the hair follicle insertion probe 11 of FIG.

  The hair follicle insertion probe 21 as a whole is made of a conductive resin material having a circular outer diameter in cross section, and has a mounting portion 21A with a large diameter on the base side, and a hair follicle insertion portion 21B with a thin diameter at the tip. Is formed.

  The distal end portion 21B1 of the hair follicle insertion portion 21B has a rounded outer diameter shape as shown in FIG. 4 and is provided with a liquid agent discharge port 21B2 communicating with the liquid agent guide hole 22 as shown in FIG. ing.

  Thus, when the hair follicle insertion portion 21B of the hair follicle insertion probe 21 is inserted into the hair follicle 15 after the tip is aligned with the pore, the tip resistance of the hair follicle insertion portion 21B increases the wall surface of the hair follicle. The tip 21B1 is smoothly inserted into the position of the hair root 17 (FIG. 2) without piercing.

  Here, the standard of the puncture resistance is determined by the JIS T 3101 injection needle standard for the injection needle, and the hypodermic injection needle has a shape value as shown in FIG. gf] is defined below. Further, the needle for dental local anesthesia has a puncture resistance of 20 [gf] or less due to the shape shown in FIG.

  According to the experiment, the penetration resistance of the hair follicle insertion probe 21 shown in FIG. 3 (the dimensions [mm] of each part are shown in FIG. 3) is about twice that of the injection needle for dental local anesthesia, that is, 40 [gf]. It was confirmed that the value was appropriate.

  The hair follicle insertion probe 21 in FIG. 3 has a luer lock connector 23 at the base end of the mounting portion 21A, and is attached to the probe holder 5 by the luer lock connector 23 as shown in FIG.

  As shown in FIG. 8A, the probe holder 5 is composed of a main body portion 5A connected to the cable 6 and the liquid agent pipe 10 and a cap portion 5B. The cap portion 5B is indicated by an arrow a in FIG. As shown in FIG. 8, when the cap part 5B is fully slid to the base side, it is provided at the front end of the main body part 5A as shown in FIG. 8C. The connection port 5C is exposed to the tip side of the cap 5B.

  As shown in FIG. 8D, the luer lock connector 23 of the hair follicle insertion probe 21 is fixed to the hair follicle insertion probe 21 by screwing it into the connection port 5C, and the liquid agent at the tip of the hair follicle insertion portion 21B. The liquid agent supplied from the liquid agent pipe 10 to the discharge port 21B2 can be discharged.

  In this state, as shown by an arrow b in FIG. 8E, if the cap portion 5B is pulled back to the original position to cover the luer lock connector 23, the practitioner grasps the cap portion 5B and moves the hair. The operation (FIG. 2) of inserting the hair follicle insertion portion 21B of the packet insertion probe 21 into the hair follicle 15 can be performed.

  In the above configuration, if the operation switch 12 (FIG. 1) is operated with the hair follicle insertion probe 21 attached to the probe holder 5 inserted into the hair follicle 15, the liquid agent supplied from the liquid agent tank 9 is inserted into the hair follicle. The liquid agent discharge port 21B2 (FIG. 5) of the portion 21B is supplied to the periphery of the hair follicle 15 or the hair root portion 17, and the ion osmotic current (0.1 [mA] or less) supplied from the hair follicle insertion portion 21B. The active ingredient of the solution can be absorbed and absorbed.

  The active ingredient of the ionized solution is in a state where it can be easily permeated and absorbed by the root tissue (hair papilla) of the hair root part 17, and thus the hair growth effect or hair growth inhibiting effect and hair removal effect of the hair root tissue as needed. You can adjust it.

  According to the above configuration, since the hair follicle insertion probe 21 is made of a conductive resin material, there is no possibility of inducing metal allergy when the hair follicle insertion portion 21B is inserted into the hair follicle 15, so that it is safe. Can be treated.

  In addition, since the hair follicle insertion portion 21B exhibits the flexibility that is unique to the conductive resin material, the hair follicle insertion portion 21B is coupled with the roundness of the tip portion 21B1 of the hair follicle insertion portion 21B. Can be inserted smoothly.

  Further, the tip 21B1 of the hair follicle insertion portion 21B is rounded, so that when the hair is aligned with the pores, careless puncture to the skin when the position is not correct is prevented, and the hair follicle is inserted. When the part 21B is inserted into the hair follicle 15, the possibility that the tip 21B1 carelessly pierces and damages the wall surface of the hair follicle 15 can be reduced.

  Furthermore, since the hair follicle insertion portion 21B is made of a conductive resin material, the conduction resistance (electrical resistance) can be reduced to about 1000 [Ω], thereby obtaining an ion osmotic current of 0.1 [mA] or less. Therefore, the configuration of the necessary ion permeation power source 3 can be sufficiently miniaturized (it can be miniaturized to the extent that it can be carried).

(3) Second Embodiment FIG. 9 shows a second embodiment. As shown in FIG. 3 with the same reference numerals attached to the corresponding parts to FIG. A pair of liquid guide holes 25A and 25B having a circular arc cross section are provided.

  In this case, as shown in FIG. 10, the hair follicle insertion portion 21B provided at the distal end of the mounting portion 21A is rounded at the distal end portion 21B1, and the liquid agent guide hole 22 described above with reference to FIG. Such a liquid guide hole is not provided.

  In this case, a stepped portion 21C is provided between the hair follicle insertion portion 21B and the mounting portion 21A so that the outer diameter gradually increases toward the root side, and the boundary between the stepped portion 21C and the hair follicle insertion portion 21B. As shown in FIG. 11, liquid agent discharge ports 26A and 26B communicating with the liquid agent guide holes 25A and 25B are formed at the positions.

  In the above configuration, if the practitioner operates the operation switch 12 (FIG. 1) with the hair follicle insertion portion 21B inserted into the hair follicle 15 of the person to be treated, it is introduced by the liquid guide holes 25A and 25B each time. The liquid agent is discharged from the liquid agent discharge ports 26A and 26B provided on the base side of the hair follicle insertion portion 21B.

  The discharged liquid agent flows around the hair follicle insertion portion 21B and accumulates between the hair follicle 15 and the hair root portion 17, and the active ingredient of the accumulated liquid agent is supplied from the hair follicle insertion portion 21B. It is absorbed and absorbed into the hair follicle 15 or the hair root portion 17 by the ion osmotic current.

  As a result, since many active ingredients of the liquid agent are easily permeated around the hair root part 17, a hair growth effect or hair growth suppressing effect on the hair root tissue of the hair root part 17 or a hair removal effect is required. Can be adjusted accordingly.

  Therefore, the hair follicle insertion probe 21 is made of a conductive resin, so that there is no risk of inducing metal allergy, and the tip of the hair follicle insertion portion 21B is rounded, so that Inadvertent puncture of the skin when the position is not correct can be prevented, and a safe hair follicle insertion probe 21 with a low possibility of inadvertently piercing the wall surface of the hair follicle can be inserted.

(4) Third Embodiment FIG. 12 shows a third embodiment. In this case, the hair follicle insertion probe 31 is inserted through the inside as described above with reference to FIGS. The liquid agent guide hole is not provided.

  The hair follicle insertion probe 31 is made of a conductive resin as a whole, and has a configuration in which a hair follicle insertion portion 31B having a thin diameter is connected to the tip of a thick outer diameter circular mounting portion 31A at the position of the step portion 31C. Have

  As shown in FIG. 13, the tip portion 31B1 of the hair follicle insertion portion 31B has a rounded outer diameter shape as a whole, and a liquid agent attachment portion that is drilled so as to form a groove from the tip surface to the root side. 31B2 is provided.

  In this case, the liquid agent pipe 10 from the liquid agent tank 9 is not connected to the probe holder 5 (FIG. 1), and the liquid agent to be supplied to the hair follicle is attached to the liquid agent attaching portion 31B2.

  In the above configuration, the practitioner who has the probe holder 5 inserts the hair follicle insertion portion 31B into the hair follicle 15 of the treatment subject with the liquid agent attached to the liquid agent attachment portion 31B2.

  At this time, the tip of the hair follicle insertion portion 31B has a length that reaches the hair root portion 17 (FIG. 2), so that the liquid agent attached to the liquid agent attachment portion 31B2 is directly supplied to the hair root portion 17.

  In this state, when the practitioner operates the operation switch 12 (FIG. 1), an ion osmotic current flows through the hair follicle insertion probe 31 each time, so that the hair root portion 17 and the liquid agent supplied around it are The active ingredient is easily absorbed and absorbed by the hair root tissue of the hair root portion 17.

  Thus, according to the configuration of FIG. 12, the hair follicle insertion probe 31 is made of a conductive resin, so that it is possible to effectively avoid the risk of inducing metal allergy, and the hair follicle insertion portion 31B is bent. The hair follicle insertion portion 31B can be inserted smoothly into the pores with a low possibility of piercing the skin or the inner wall surface of the hair follicle in combination with the roundness of the hair follicle tissue (particularly directly on the root tissue ( The liquid agent of the liquid agent attaching part 31B2 can be easily supplied to the hair papilla).

  Thus, the hair-growth effect or hair growth-suppressing effect of the hair root tissue and the hair removal effect can be adjusted as necessary.
