Abstract

[Problem] To provide a vacuum impregnating device for hair growth and hair growth in which a chemical solution is permeated into pores by an extremely simple operation and can be easily handled at home. A hair-growth / hair-growth vacuum impregnation device 10 includes a suction cup 12 and an expansion / contraction pump 13. The suction chamber S1 of the suction cup 12 communicates with the pump chamber S2 through the vent hole H1, and the pump chamber S2 is opened to the outside air through the vent hole H2 of the telescopic pump 13. The valve element 18 is supported by the spring plate 17 (spring material) while maintaining a gap at the opening of the vent hole H2. The valve body 18 closes the vent hole H2 against the urging force of the spring plate 17 due to the inertial force of the valve body 18 when the suction plate 12 is struck against the scalp, and the spring plate 17 is restored when the suction plate 12 is pulled up from the scalp. The vent hole H2 is opened by force. As the valve body 18 is opened and closed, the reduced pressure state of the sealed chamber (adsorption chamber S1) between the scalp and the suction cup is opened momentarily, so that the chemical solution can be sucked into the pores of the scalp.

Description

  The present invention relates to a hair growth / hair growth vacuum impregnation device, and more particularly, to a hair growth / hair growth vacuum impregnation device suitable for infiltrating a chemical solution into pores. The vacuum impregnating device according to the present invention can also be used as a vacuum impregnating device for percutaneous absorption for allowing a drug solution such as pharmaceuticals and cosmetics to penetrate into the skin.

Conventionally, a vacuum impregnation device for hair growth and hair growth in which a chemical solution is permeated into the pores of the scalp using a suction cup with a vent is known (see Patent Documents 1 and 2). This type of vacuum impregnating tool has a suction cup composed of a circular base portion and an outer peripheral skirt portion, and a vent hole penetrating the inside and the outside of the suction cup is provided in the base portion.
When using a vacuum impregnating device, apply a chemical solution to the scalp in advance, block the vent hole by hand, and press the suction pad against the scalp to make it adsorb. Thereafter, when the suction cup is pulled up, the sealed space between the scalp and the suction cup is decompressed, and air is sucked out from the pores. Thereafter, when the hand is pulled away from the vent hole, the outside air enters the inside of the suction cup, and the adsorbed state (decompressed state) of the scalp is instantaneously released. With this decompression and release, the pores return to the original state, and the chemical solution inside the suction cup enters the pores.

However, such a conventional hair-impregnating / hair-growth vacuum impregnating device manually opens and closes the air vents, which makes the operation troublesome. In addition, since the suction force of the suction cup is weak, the reduced pressure state of the scalp may not be sufficiently increased. Furthermore, if the impregnating tool is handled without fully understanding the operation method, it may happen that the opening and closing timing of the vent hole is mistaken and the chemical solution does not enter the pores effectively.
On the other hand, attending a salon or the like to receive treatment using a dedicated hair-growth / hair-growth vacuum impregnation device is likely to be deceived due to the increased effort and cost.

  The present invention has been made in view of such a current situation, and provides a hair impregnation / hair growth vacuum impregnation device that can efficiently penetrate a chemical solution into pores with a simple operation and can be easily handled at home. The purpose is that.

[First invention]
The vacuum impregnation tool for hair growth and hair growth of the present invention (first invention) for solving the above problems is as follows.
In a vacuum impregnating tool for hair growth and hair growth having a suction cup composed of a base part and a skirt part, and having a vent hole penetrating the inside and the outside of the suction cup in the base part of the suction cup or its peripheral part,
A valve body provided outside the suction cup and at the opening of the vent hole;
A spring material that supports the valve body so that the vent can be opened and closed;
The valve body closes the vent hole against the biasing force of the spring material due to the inertial force of the valve body when the sucker is struck against the scalp, and the spring material when the suction cup is pulled up from the scalp It is characterized in that the vent hole is opened by a restoring force.

According to the hair impregnation device for hair growth / growth of the present invention (first invention), when a chemical solution is applied to the scalp and the suction cup is struck, the air vent is formed by the inertial force at the moment when the suction cup hits the scalp and stops. The closed space is temporarily formed between the scalp and the suction cup. Immediately after the suction cup hits the scalp, if the suction cup is pulled up from the scalp using the reaction, the sealed space is sucked and decompressed, and the scalp pores are contracted. Thereafter, when the valve body is separated from the vent hole due to the restoring force of the spring material, outside air enters the sealed space from the vent hole, and the air pressure instantaneously rises, and at the same time, the chemical solution is sucked into the pores of the scalp.
As described above, according to the present invention (first invention), the valve body and the spring material automatically open and close the vent holes at an appropriate timing in accordance with the operation of hitting the scalp with the suction cup, and the sealed space for vacuum impregnation. Control the pressure. Thereby, a chemical | medical solution can be reliably osmose | permeated to the pore of a scalp by simple operation, without using the vacuum impregnation apparatus for hair growth and hair growth which uses a hair cap etc. for exclusive use.

According to the present invention (second invention), when the suction cup is struck against the scalp, the telescopic pump contracts by the inertia force at the moment when the suction cup hits the scalp and sends compressed air to the sealed space between the scalp and the suction cup. This compressed air gives moderate stimulation to the scalp and promotes a massage effect.
On the other hand, when the suction cup is pulled up from the scalp, the telescopic pump tries to return to the original state from the contracted state, and therefore, the air in the sealed space of the suction cup is sucked out by this restoring force. As a result, the degree of decompression of the sealed space can be increased, and the chemical solution can be easily sucked into the pores of the scalp when the decompression is released.

That is, the user needs to immerse the chemical in the scalp by himself, resulting in inconveniences such as the user's hands getting dirty and the application amount being varied.

In the present invention (third invention), the telescopic pump sends compressed air to the vent hole in accordance with the operation of hitting the scalp with the suction cup, and the chemical liquid can be discharged from the chemical nozzle to the vent hole by this compressed air flow.
As a result, it is possible to send the chemical solution to the sealed space of the scalp through the vent hole, and it is possible to eliminate the trouble of applying the chemical solution to the scalp in advance and the user's hand becoming dirty with the chemical solution.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
[First Embodiment]
The hair impregnation tool for hair growth and hair growth of the first embodiment is shown in FIG.
The vacuum impregnation tool 10 for hair growth / hair growth is provided with an expansion pump 13 on the rear end side (upper side in FIG. 1) of the suction cup 12. A handle 14 is attached to the side of the suction cup 12.
A strip-shaped core rod 15 made of a steel material extends from the handle 14, and an annular band 16 is fixed to the tip of the core rod 15. An annular band 16 is fastened to the rear end portion of the suction cup 12 with a screw or the like.

A spring plate 17 branches and extends in the middle of the core rod 15. A valve body 18 capable of opening and closing the vent hole H2 (see FIGS. 2 and 3) of the expansion / contraction pump 13 is attached to the tip of the spring plate 17.
A chemical reservoir 19 is attached to the side of the suction cup 12, and the chemical liquid in the chemical reservoir 19 is supplied to the vent hole H <b> 1 (see FIG. 4) of the suction cup 12 through the connection pipe 20. Yes.

The suction cup 12 is made of an elastic material such as silicon or rubber, and as shown in FIG. 4, a tapered skirt portion 22 is connected to a columnar base portion 21. When the suction cup 12 is pressed against the scalp, the skirt portion 22 is deformed so as to expand and adheres to the scalp.
As shown in FIG. 4, a vent hole H <b> 1 penetrates through substantially the center of the suction cup 12. The vent hole H1 extends in the central axis direction of the base portion 21 and communicates with the suction chamber S1 inside the skirt portion 22.

The expansion pump 13 is made of a soft resin material, and is configured to expand and contract a bellows-shaped cylindrical portion 25. The lower end of the cylinder part 25 is airtightly fixed to the end surface (upper side surface in FIG. 4) of the suction cup 12. As the cylindrical portion 25 expands and contracts, the pump chamber S2 expands or contracts, and the suction chamber S1 is depressurized or pressurized through the vent hole H1.
A lid portion 26 is integrally formed on the upper side of the cylindrical portion 25, and a vent hole H <b> 2 is formed at the center of the lid portion 26. That is, outside air can be taken into the pump chamber S2 through the vent hole H2, or the air in the pump chamber S2 can be discharged to the outside.

  As shown in FIG. 1, the valve body 18 is supported by the spring plate 17 with a slight clearance above the vent hole H2. The outer diameter of the disc-shaped valve body 18 is larger than the vent hole H2 (see FIG. 3). When the spring plate 17 is stationary, the valve body 18 is in a position away from the vent hole H2, so that the valve body 18 keeps the vent hole H2 open. When the spring plate 17 is bent and the valve element 18 hits the lid portion 26, the vent hole H2 is closed.

The connecting pipe 20 of the chemical reservoir 19 penetrates to the side of the suction cup 12 and protrudes into the vent hole H1 (see FIG. 3). A chemical liquid nozzle 20a that discharges the chemical liquid to the vent hole H1 is provided at the tip of the connecting pipe 20 that opens to the vent hole H1.
In addition, the detachable cap 19a is attached to the chemical solution reservoir 19 (see FIG. 2), and the chemical solution can be filled into the reservoir by removing the cap 19a. In addition, an intake hole 19b is provided on the cover surface of the cap 19a. When the chemical liquid in the reservoir is discharged from the chemical nozzle 20a, outside air is sucked into the reservoir through the intake hole 19b.

Next, the usage method of the hair impregnation tool 10 for hair growth and hair growth is demonstrated.
First, the user fills the chemical reservoir 19 with a necessary chemical solution in advance. Next, as shown in FIG. 5, the sucker 12 is held with the handle 14 facing the scalp. Then, the handle 14 is swung down and the scalp is hit with the suction cup 12.

In the state where the handle 14 is held, the spring plate 17 is stationary, so that the valve body 18 is in a state of floating with a slight gap from the vent hole H2. That is, the vent hole H2 is in an open state.
As shown in FIG. 6, when the suction cup 12 is struck against the scalp, the spring plate 17 and the valve body 18 bend toward the vent hole H2 due to the inertial force at the moment when the suction cup 12 hits the scalp. Close the pores H2. At this time, the adsorption chamber S1 and the pump chamber S2 are cut off from the outside air and are in a sealed state (sealed space). When the telescopic pump 13 is further contracted by inertia force from this state, compressed air is sent from the pump chamber S2 to the adsorption chamber S1 through the vent hole H1.
The amount of bending (bending width) of the spring plate 17 is set to be sufficiently larger than the amount of expansion (extension / contraction length) of the expansion pump 13. That is, when the suction cup 12 hits the scalp, the spring plate 17 (valve element 18) bends toward the scalp so as to push down the telescopic pump 13. As a result, as described above, it is possible to seal and pressurize the pump chamber S2 by closing the vent hole H2 with the valve body 18.

  Part of the compressed air that passes through the vent hole H1 enters the chemical reservoir 19 side from the connection pipe 20, and at the same time, a small amount of chemical is ejected from the chemical nozzle 20a. And this chemical | medical solution diffuses in adsorption chamber S1, and is sprayed on a scalp.

When the sucker 12 is struck against the scalp and then the handle 14 is pulled up using the reaction, the sucker 12 rises in a direction away from the scalp as shown in FIG. Moreover, since the expansion pump 13 tries to return to the original shape as the spring plate 17 rises, the air in the adsorption chamber S1 is sucked into the pump chamber S2. As a result, the suction chamber S1 is depressurized, and the pores T of the suction chamber S1 are in a state where the sebum is sucked out and is slightly contracted.
In addition, in the stage of FIG. 7, the valve body 18 is maintained in the state of closing the vent hole H2.

  When the spring plate 17 is further raised from the state of FIG. 7, the valve body 18 is pulled away from the vent hole H2. Then, as shown in FIG. 8, outside air enters the pump chamber S2 from the vent hole H2, and instantaneously increases the internal pressure of the adsorption chamber S1 through the vent hole H1. At this time, the pore T returns to the original state, and at the same time, the chemical solution in the adsorption chamber S1 enters the pore T. That is, the pore T is subjected to vacuum impregnation with a chemical solution.

  When the suction chamber S1 and the pump chamber S2 return to positive pressure (atmospheric pressure), the suction cup 12 can be easily pulled away from the scalp. The user repeatedly performs the operation of swinging up the suction cup 12 and hitting the scalp as shown in FIGS.

  As described above, according to the hair-impregnation / hair-growth vacuum impregnation tool 10 of the present embodiment, the chemical solution can be easily and surely penetrated into the pores of the scalp only by repeatedly hitting the scalp with the suction cup 12. . Since the opening / closing of the air hole H2 by the valve body 18 is automatically performed in accordance with the user's tapping operation, the valve body 18 can be opened / closed at an appropriate timing without the user being aware of the operation of the valve body 18 at all. Can be controlled.

Further, in the hair-growth / hair-growth vacuum impregnation tool 10 of the present embodiment, the expansion pump 13 pressurizes and depressurizes the adsorption chamber S1 (sealed space), so that the pressure change in the adsorption chamber S1 can be further increased. . As a result, the effect of sucking sebum from the pores and the effect of impregnating the pores with the chemical solution when the pressure is released are increased.
Furthermore, according to the present embodiment, the chemical liquid can be sprayed on the scalp by the chemical liquid nozzle 20a, and the effect of penetration of the chemical liquid into the pores can be enhanced. In addition, for the user, there is no need to apply a chemical solution to the scalp in advance, and the inconvenience that the hand is stained with the chemical solution is also eliminated.

[Second Embodiment]
A second embodiment of the present invention is shown in FIG.
The hair growth / hair growth vacuum impregnation tool 30 of the second embodiment is a simplified structure of the hair growth / hair growth vacuum impregnation tool of the first embodiment, and omits the structures of the expansion pump and the chemical reservoir.
As shown in FIG. 9, a handle 14 is provided on the side of the suction cup 12, and a core rod 15 extends at the tip of the handle 14. An annular band 16 at the tip of the core rod 15 is fastened to the suction cup 12.
A valve body 18 is provided on the spring plate 17 branched from the core rod 15. The valve body 18 is supported by the spring plate 17 while maintaining a gap with the substantially central vent hole H of the suction cup 12.

When using the hair-growing / hair-growth vacuum impregnation tool 30, the user applies a chemical solution to the scalp in advance, and hits the scalp with the suction cup 12 in the same manner as in the first embodiment.
As shown in FIG. 10, when the user holds up the suction cup 12 on the scalp, the valve body 18 is away from the suction cup 12 and the vent hole H is opened. As shown in FIG. 11, when the handle 14 is swung down and the suction cup 12 is struck against the scalp, the spring plate 17 is bent downward by the inertial force at the moment when the suction cup 12 hits the scalp and the vent hole H is blocked by the valve element 18. . At this time, the suction chamber S inside the suction cup 12 is sealed.

After the suction cup 12 is struck against the scalp, if the suction cup 12 is lifted from the scalp, the suction chamber S rises in a direction away from the scalp, as shown in FIG. Aspirated and contracted.
Next, since the spring plate 17 lifts the valve element 18 upward by its restoring force, the vent hole H is opened and the outside air enters the adsorption chamber S. At this time, the internal pressure of the suction chamber S in the reduced pressure state instantaneously increases, and the scalp chemical enters the pores (see FIG. 13).

  As described above, according to the second embodiment, the chemical solution can be permeated into the pores of the scalp with a very simple configuration and with a simple operation of simply hitting the scalp with a suction cup. In addition, since parts such as an expansion pump and a chemical reservoir are unnecessary, the manufacturing cost can be greatly reduced.

[Third Embodiment]
FIG. 14 shows a hair impregnation / hair growth vacuum impregnation tool 40 according to the third embodiment.
The hair growth / hair growth vacuum impregnation tool 40 employs a spindle-shaped expansion / contraction pump 41 made of an elastic material instead of the bellows type expansion / contraction pump of the first embodiment. About the usage method of the vacuum impregnation tool 40, it is the same as that of the vacuum impregnation tool 10 of 1st Embodiment.
According to the structure of 3rd Embodiment, in addition to the effect similar to the said 1st Embodiment, since the structure of the expansion-contraction pump 41 becomes simple, there exists an effect that it becomes easy to aim at reduction of manufacturing cost.

[Fourth Embodiment]
FIG. 15 shows a hair impregnation / hair growth vacuum impregnation tool 50 according to the fourth embodiment. In the fourth embodiment, a coil spring is used in place of the spring plate of the first and second embodiments.
The hair-impregnation / hair-growth vacuum impregnation tool 50 is configured such that a coil spring 51 is attached to the rear end of the base 21 of the suction cup 12 and the valve body 52 is supported by the coil spring 51. When the valve body 52 hits the suction cup 12 against the urging force of the coil spring 51, the vent hole H is closed. On the other hand, when the valve body 52 is pushed back upward in FIG. 15 of the suction cup 12 by the urging force of the coil spring 51, the vent hole H is opened. The user can perform vacuum impregnation of the chemical liquid into the scalp by hitting the scalp directly with the suction cup 12 as in the second embodiment.
According to the fourth embodiment, the configuration of the handle 14, the core rod 15, the annular band 16, and the spring plate 17 is not necessary, so that the configuration of the vacuum impregnation tool can be made more compact.

[Fifth Embodiment]
FIG. 16 shows a hair impregnation / hair growth vacuum impregnation tool 60 according to the fifth embodiment. In the fifth embodiment, the spring plate 17 and the valve body 18 of the first embodiment are omitted, and the vent hole H2 of the expansion pump 13 is manually opened and closed.
The vacuum impregnation tool 60 for hair growth / hair growth is integrally fixed with a bellows type expansion / contraction pump 13 at the rear end of the base 21 of the suction cup 12. A vent hole H1 passes through the base 21 in the central axis direction, and the suction chamber S1 of the suction cup 12 and the pump chamber S2 of the telescopic pump 13 communicate with each other through the vent hole H1. A vent hole H2 communicating with the pump chamber S2 is opened in the lid portion of the telescopic pump 13.

  A chemical reservoir 19 is provided on the side of the suction cup 12. A connecting pipe 20 that guides the chemical solution in the chemical reservoir 19 to the vent hole H1 passes through the base 21 of the suction cup 12. A chemical liquid nozzle 20a capable of discharging a chemical liquid to the vent hole H1 is provided at the tip of the connecting pipe 20 that opens to the vent hole H1.

  When the hair-growing / hair-growth vacuum impregnation tool 60 is used, first, as shown in FIG. 16, the chemical solution reservoir 19 is filled with an appropriate amount of chemical solution, and the suction cup 12 is applied to the scalp. Next, as shown in FIG. 17, the vent hole H2 of the expansion pump 13 is closed by hand, the expansion pump 13 and the suction cup 12 are pressed toward the scalp, and the air in the pump chamber S2 and the suction chamber S1 is pushed out.

  This pressing operation is performed with a relatively strong force so that the compressed air from the pump chamber S2 passes through the vent hole H1 vigorously. As a result, the compressed air flow passing through the vent hole H1 enters the chemical reservoir 19 side from the connection pipe 20 and discharges a part of the chemical from the chemical nozzle 20a. And this chemical | medical solution diffuses in adsorption chamber S1, and is sprayed on a scalp.

  When the user pulls up the telescopic pump 13 from the state of FIG. 17, the suction chamber S1 and the pump chamber S2 are expanded and the degree of decompression is increased as shown in FIG. In the suction chamber S1, sebum and the like are sucked out from the pores T of the scalp. At this time, since the pump chamber S2 is also kept in a reduced pressure state, the user's hand remains attached to the vent hole H2.

  After sufficiently increasing the degree of decompression of the adsorption chamber S1 and the pump chamber S2, as shown in FIG. 19, when the user's hand is pulled away from the vent hole H2, the outside air is vigorously forced from the vent hole H2. S1 enters and the internal pressure of these spaces instantaneously returns to positive pressure (atmospheric pressure). At this time, the scalp pore T is restored from the contracted state, and at the same time, the chemical in the adsorption chamber S1 is sucked into the pore T.

As described above, according to the hair-impregnation / hair-growth vacuum impregnation tool 60 of the fifth embodiment, the user performs the pressure reduction release at an appropriate timing by alternately performing the pressing operation and the pulling-up operation of the expansion pump 13 and the suction cup 12. It is possible to easily impregnate the scalp pores with a chemical solution.
Further, since the chemical liquid is fed from the chemical liquid nozzle 20a into the adsorption chamber S1 using the compressed air in the vent hole H1, there is less variation in the supply amount of the chemical liquid. Furthermore, the user does not need to apply the chemical solution to the scalp, and the hands are not easily stained with the chemical solution. Furthermore, since it is a compact and simple configuration, there is an advantage that manufacturing costs can be easily suppressed.

[Skin permeability test]
In skin external preparations such as pharmaceuticals and cosmetics, in order to sufficiently exert the effect of the active ingredient, it is a problem to improve the transdermal absorbability to the skin.
However, since the stratum corneum of the skin has a barrier function consisting of a layer structure of hydrophobic intercellular lipids and hydrophilic keratin proteins, the percutaneous absorption of drugs from the outside is remarkably limited.
Conventionally, in order to improve the transdermal absorbability of active ingredients, many studies have been conducted, such as a method using a transdermal absorption enhancer and a method using ultrasonic waves and electricity. It is not realistic in terms of breaking the barrier function of the layer or using a complicated machine.
According to the vacuum impregnation device for percutaneous absorption of the present invention, the permeability of the chemical liquid to the skin can be efficiently increased by a simple operation. Test examples for confirming skin permeability with a vacuum impregnation tool are shown below.

(1) Test impregnation tool A suction cup with a vent was used as the test impregnation tool. The suction cup with a vent has the same configuration as the suction cups included in the first to fifth embodiments, and has a circular base at the center, a skirt on the outer periphery of the base, and a central shaft of the base This is a type having through holes in the direction (see FIGS. 20 and 21).

(2) Sample As a sample for transdermal administration, indocyanine green (ICG: manufactured by Santen Pharmaceutical Co., Ltd.), which is used for intravenous injection as a test reagent for liver function metabolism or used in recent ophthalmic cataract surgery, is used. Using. An ICG solution having a concentration of 30 mg / ml was prepared using a 50% aqueous ethanol solution as a solvent and used for the test.

(3) Test skin Yucatan micropig skin, which has already been reported to be useful for predicting skin permeability, was used as the skin tissue for testing, which has a structure relatively close to that of human skin. . Yucatan micropig 5-month-old female, back skin was used as test skin.

(4) Test method 200 μl of ICG solution was applied to the center of the skin of a 10 cm × 10 cm Yucatan micropig and allowed to stand for 1 minute. Thereafter, an operation of pressurizing the test impregnating tool on the test skin (see FIG. 20) and an operation of opening the vent of the test impregnating tool (see FIG. 21) are sequentially performed. Repeated 5 and 10 times. In addition, the thing which left still for 1 minute and was not pressurized was made into control.
Immediately after the pressurization / release operation, the skin was cut into 5 mm squares and fixed by immersion overnight in a 4% isotonic buffered paraformaldehyde solution (pH 7.4). After fixation, wash with phosphate buffer (PBS: pH 7.4), freeze-embed with OCT compound [Tissue-Tek], slice into cryostat (10μm thickness) and place on silane-coated slide glass Affixed and immediately dried under cold air. Then, it encapsulated with a water-soluble encapsulant, and performed fluorescence microscope observation (magnification 40 times) and image analysis.

(6) Results
The change in ICG skin permeability is shown in FIG. In FIG. 22, “DICI” indicates a differential interference contrast image, and “FI” indicates a fluorescence image.
In the control, ICG skin penetration was not observed, but as the number of manipulations increased, the ICG skin permeability increased, and the ICG penetrated the epidermis layer 5 times and the dermis layer 10 times. Observed. The amount of ICG permeation in the epidermis and dermis layers was analyzed by image analysis software, and it was confirmed that the skin permeation amount of ICG increased in proportion to the number of operations in both the epidermis layer and the dermis layer.

From the above results, it can be seen that the vacuum impregnation device of the present invention has an effect of directly infiltrating the chemical into the skin. Moreover, skin permeability can be increased, so that the operation frequency of a vacuum impregnation tool is increased.
In the above-mentioned skin penetration test, a test impregnation tool using a suction cup with a ventilation hole was used alone, but the first to fifth implementations were performed as instruments for promoting percutaneous absorption (vacuum impregnation tool for percutaneous absorption). A vacuum impregnation tool having a configuration similar to that of the form can also be used. By using the vacuum impregnating device having such a configuration, it is possible to efficiently infiltrate the drug solution into the skin with a simpler operation.
