DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a scalp capillary growth device, and an object of the present invention is to provide a device capable of not only preventing hair loss but also causing new hair growth on the scalp at a hair loss site. It is in.

[0002]

2. Description of the Related Art There are various causes of alopecia, such as stress, androgen, dirt on the scalp, and lack of nutrition in the hair root due to poor blood circulation in the scalp is also considered to be the main cause. I have. Therefore, conventionally, a method of applying a hair restorer containing a component that penetrates the hair root and expands blood vessels to the scalp, a method of massaging the scalp using hands and instruments, or a method of warming the scalp with far infrared rays, The blood circulation of the scalp is promoted by various methods.

However, the conventional method as described above does not provide a sufficient hair-growth effect. This is because it is difficult to penetrate the hair growth agent to the root of the hair, only temporary blood circulation can be obtained, or nutrients are added to the hair root in areas where capillary blood vessels are already lost even if blood circulation is promoted. Can not be carried.

[0004] Therefore, many other methods have been proposed for promoting blood circulation by expanding the capillaries by vacuum suction of the scalp.

[0005]

However, most of the conventional hair-growing devices using suction are constructed so that the entire head is covered with a cap, and the inside of the cap is suctioned with a negative pressure. Therefore, the following issues existed. In other words, if a suction tool with a large opening surface that covers the entire head is used, the opening surface is tightly fixed to the temporal region, so that the temporal region is tightened and blood flow to the top of the head becomes worse. And
This had the opposite effect on hair growth. Also, alopecia usually does not occur over the entire head, but at specific local sites such as the crown or frontal region. The negative pressure could not be effectively applied to the required specific site.

On the other hand, as a technique for sucking the scalp using a small-diameter suction tool, Japanese Utility Model Publication No. 2-15476 "Hair treatment apparatus" exists. The disclosed technology includes a massage slip sucker, a fixing sucker, and a vacuum generator, and a device for processing a part of the scalp under a variable vacuum, wherein the diameter of the massage slip sucker is in a range of 10 to 20 mm. And the diameter of the fixing suction cup is in the range of 25 to 50 mm. However, this "hair treatment device" is merely a technique for preventing hair loss, not a technique capable of causing new hair growth at a hair loss site, and fundamentally solves the concerns of thin haired people. It was not something that could be done.

The inventors of the present application have conducted intensive studies on a method for generating new hair growth at a hair loss site. As a result, a certain number or more of capillaries are formed in a certain area by suction for hair growth. It has been found that this capillary formation can only occur when the scalp is aspirated under certain aspiration conditions. Specifically, it has been found that hair growth requires at least 6 capillaries per 1 mm ² , and the formation of these capillaries requires the scalp to be raised by at least 12 mm. . And, in the disclosed technology of Japanese Utility Model Publication No. 2-15476,
It turns out that this condition cannot be satisfied.

That is, in the apparatus disclosed in Japanese Utility Model Publication No. 15476/1990, since the diameter of the suction tool is too small, the scalp cannot be sufficiently raised by suction. Of course, it was possible to raise the scalp by 12 mm or more by greatly increasing the suction pressure, but the scalp was excessively congested during the suction, causing severe pain to the subject, and the suction was not stopped. Did not get.

The inventor of the present invention has conducted numerous experiments in order to establish the conditions for hair growth found by himself as actual treatment conditions, and has completed the present invention.

[0011]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a scalp capillary growth device according to the present invention will be described below with reference to the drawings. FIG. 1 is a configuration diagram showing a preferred embodiment of a scalp capillary growth device according to the present invention. As shown in the figure, a scalp capillary growth device according to the present invention includes a suction tool (1) attached in close contact with the body surface of a subject (H), and a suction tool (1) and a hose (2). And a vacuum pump (3) for connecting the suction tool (1) to a negative pressure state.

A hose (2) connecting the vacuum pump (3) and the suction tool (1) is provided with a level gauge (4) and an opening valve (5). (1) The level of the internal negative pressure is adjusted, and the adjusted pressure value is read by the level gauge (4).

FIG. 2 is an external view showing an embodiment of the suction tool (1), and FIGS. 3 and 4 are a cross-sectional view and a bottom view, respectively, showing the shape of the opening surface of the suction tool. FIG. 3 shows only the lower part of the suction tool. Suction tool in this example (1)
Is a connecting portion of a crown (12) made of a hard material such as glass or acrylic resin and having a circular opening surface (11) and a hose (2) attached to the top of the crown (12). 13), and as shown in FIG.
By operating the vacuum pump (3) in a state where the opening surface (11) is in contact with the body surface of the subject, the air in the crown portion (12) is sucked from the hose (2) and the suction tool is sucked. (1) It is configured so that the inside is in a negative pressure state.

The thickness of the crown (12) of the suction tool (1) is
As shown in FIG. 3, the peripheral edge (15) of the opening surface (11) is formed so as to be thicker outward and has a rounded shape. By forming the peripheral edge of the opening surface in such a shape, the contact area of the suction tool with the scalp can be reduced, and when the scalp is sucked, the scalp around the suction tool is simultaneously sucked up. It can be raised.

The peripheral edge of the opening surface (11) of the suction tool (1) has a saddle shape as a whole by forming upwardly curved portions at opposing positions of the peripheral edge.
When the saddle shape is divided into left and right sections, a shape (curved portion) protruding toward the central portion appears as shown in FIG. As described above, by forming the shape of the peripheral portion of the opening surface of the suction tool in a saddle shape, the suction tool can be closely attached along the shape of the head.

In the present invention, when the shape of the opening surface (11) of the suction tool (1) is circular as described above, it is preferable to set the opening surface area to be 20 to 100 cm ² . This is a value set as a result of the inventor's knowledge that the following adverse effects occur even if the area of the opening surface is too large or too small, and that it has an adverse effect on hair growth. .

First, when using a suction tool having a large opening surface area that covers the entire head, the opening surface must be closely attached to the temporal region in order to maintain a good negative pressure state. . However, when the opening surface is tightly fixed to the temporal region,
The temporal region is tightened and blood flow to the top of the head is impaired, which has the opposite effect. Also, alopecia usually occurs locally at a specific site such as the top of the head and does not occur at the temporal region, but if the area of the opening is too large, the scalp will reach unnecessary parts where hair growth is not necessary. And blood circulation cannot be efficiently promoted.

In the hair growth treatment by suction, the effect is not exhibited unless the scalp is raised to some extent by suction. However, if the diameter of the suction tool is too small, a strong suction force is required to raise the scalp. The scalp is congested by the suction and the cells of the scalp are damaged. In addition, when the suction tool is brought into close contact with the scalp, the area of the peripheral edge of the opening that comes into contact with the scalp is large compared to the area of the actually sucked part, so the scalp is strongly pressed by the peripheral edge during suction. The hair root is pressed down and hair growth is inhibited. Furthermore,
When the area of the part where hair growth is desired is large, it is necessary to repeat the suction process many times.

The inventor of the present invention has repeatedly conducted experiments using a suction device having a circular opening surface. As a result, when using a suction device having a circular opening surface, the area of the opening surface was reduced to 20%.
It has been found that these problems can be surely prevented by setting the range to １００100 cm ² , and an excellent hair-growth effect is exhibited.

As described above, the area of the opening surface is 20 to 1
The setting to the range of 00 cm ² was very effective in preventing hair loss, and in this respect, it was superior to the conventional suction-type hair growth device. However, as a result of many experiments conducted by the inventor of the present application, it was found that under these conditions alone, new hair growth may not be caused at the hair loss site. Therefore, the inventor of the present application conducted further research in order to find conditions for causing new hair growth at the hair loss site. As a result, for hair growth, 6 or more capillaries per 1 mm ² were formed by suction. Need to be
It has been found that the formation of capillaries can only occur when the scalp is raised by 12 mm or more by suction.

However, since there are individual differences in the condition of the scalp,
Conditions for elevating the scalp by 12 mm or more also vary from person to person, and this condition alone may cause inconvenience in actual treatment. Then, the inventor of the present application quantitatively determined conditions for raising the scalp by 12 mm or more by suction by the following method. The inventor of the present application first studied a substitute capable of imitating the scalp and found that the thickness was 2 mm.
It has been found that a sheet made of natural rubber (NR: ASTM abbreviation) exhibits a behavior close to that of the scalp when sucked. At first, a natural rubber sheet having a thickness of 1 mm was tried, but it was found that the scalp was not suitable as a substitute for imitating the scalp, because the scalp was too large when suctioned compared to the actual scalp. .

Then, the opening surface of the suction tool is brought into close contact with the natural rubber sheet having a thickness of 2 mm (hereinafter referred to as a scalp pseudo sheet or a rubber sheet or a sheet), and in this state, the rubber sheet is raised by 12 mm or more. The possible opening area and negative pressure were investigated. The properties of the used rubber sheet (product name: BL-1001 manufactured by Irumagawa Rubber Co., Ltd.) are shown in Table 1.

[Table 1]

In the experiment for the investigation, a suction tool having a circular opening surface shown in FIG.
m, φ53 mm and φ80 mm are prepared, and 660 mmHg, 560
The measurement was performed by applying four types of pressures (negative pressures) of mmHg, 460 mmHg, and 360 mmHg.

FIG. 5 is a top view showing the experimental state, and FIG. 6 is a sectional view showing the experimental state. The scalp pseudo sheet (16)
Use a rubber sheet (16) having a length of 17 cm x a width of 17 cm x a thickness of 2 mm.
(Length 20 cm × width 20 cm × thickness 1 cm), and the periphery of the sheet (16) is a 1 cm thick white wooden crates (18) (outer shape: length 20 cm × width 20 cm, inner shape: length) (17 cm x 17 cm), insert a bolt (19) from the back into the wooden board (17) and the wooden frame (18), and screw a wing nut (20) into the tip of the bolt (19) protruding from the surface. Thereby, the sheet (16) was fixed on the wooden board. In addition, a bamboo skewer (18) having a through hole formed in the center of the wooden board (17) with a cone and having a scale for measuring the height of the protrusion in the through hole was inserted vertically upward from the back side of the wooden board (17). . In this state, the leading end of the bamboo skewer (18) should not contact the back surface of the sheet (16), and the bamboo skewer (1)
It was confirmed that there was no gap between 8) and the through hole, and there was no air leakage from the through hole. Then, the suction tool (1) having the above-described opening surface diameter is placed on the surface of the rubber sheet (16) so that the opening face is brought into close contact with the sheet, and then the inside of the suction tool (1) is subjected to negative pressure by operating a vacuum pump. The state is suctioned for 5 minutes, and the height of the protrusion of the rubber sheet (16) at this time is shown in FIG.
As shown in the figure, the tip of the bamboo skewer (18) is
It measured by applying to the back surface of 6).

The results are shown in Table 2.

[Table 2]

From the results shown in Table 2, the scalp pseudo sheet was 12 m
It has been found that in order to raise the height by m or more, it is necessary to satisfy two conditions: the diameter of the suction tool is 53 mm or more, and the pressure inside the suction tool is 560 mmHg or less.

Next, in order to confirm the actual height of the scalp, the scalp was suctioned by bringing the opening surface of the suction tool into close contact with the scalp. During suction, the pressure inside the suction tool (negative pressure)
For three minutes, 360 mmHg, 460 mmHg, and 560 mmHg. As a result, φ
360-560m for 23mm and φ37mm suction tools
Although a scalp of 12 mm or more could not be obtained in the mHg negative pressure range, a scalp of 12 mm or more could be obtained in the negative pressure range of 360 to 560 mmHg with a suction tool of φ53 mm and φ80 mm. there were.

Next, the scalp was suctioned using a suction tool having a circular opening of φ83 mm. However, it was difficult for the opening to conform to the shape of the head, and the opening was formed only on a part of the scalp. Did not contact. For this reason, the scalp was not sufficiently sucked, and even when suction was successful, the scalp became painful and the hair root was damaged due to local strong pressure on the contact site. Also, the pressure inside the suction tool of φ80 mm is 360 mm
When the suction force was made smaller than Hg and a stronger suction force was applied to the scalp, the subject complained of pain during suction and was unable to continue suction.

From the experimental results for the scalp pseudo-sheet and the scalp, the conditions for raising the scalp by 12 mm or more by suction when using a suction tool having a circular opening surface are as follows. It was determined that the pressure was 80 mm and the pressure inside the suction tool was 360 to 560 mmHg.

In the present invention, the shape of the opening surface (11) of the suction tool (1) can be other than circular. 7 to 10 are diagrams showing examples of the shape of the opening surface other than the circular shape. FIG. 7 shows an example in which the opening surface is formed in a substantially elliptical shape having an aspect ratio of about 1: 2, and the periphery of the opening surface is formed to have a thickness of about half the length of the vertical axis of the opening surface. FIG. 9 shows an example in which the surface has a substantially elliptical shape with an aspect ratio of about 3: 4.
FIG. 10 shows an example in which a part of the circumference of a substantially elliptical shape having an aspect ratio of about 1: 2 (one side of an arc substantially parallel to the long axis) is outwardly projected. This is an example of projecting in a substantially triangular shape. In addition, even when the shape of the opening surface (11) is a shape other than a circle as described above, as described above, the thickness of the spherical crown portion is directed outward at the peripheral edge of the opening surface as shown in FIG. It is preferable to form it thick and rounded so that the peripheral edge of the opening surface has a saddle shape as a whole, because the same excellent effects as described above can be obtained.

In the case where the shape of the opening surface (11) is not circular, the shape of the opening surface (11) is the shape of the part where the hair growth treatment of the subject is desired, that is, the original shape before hair loss occurs. Shape along the hair line. For example, the suction device shown in FIG. 9 is used for a person whose hair loss has progressed in the frontal head, and FIG.
11 and 12 may be attached as shown by broken lines in FIGS. 11 and 12, respectively. In this way, by making the shape of the opening surface (11) of the suction tool (1) into the shape of the part where the hair growth treatment of the subject is to be performed, the negative pressure can be locally applied only to the necessary part. It becomes possible. Note that, in addition to these shapes, other shapes that match the shape of the part where the hair growth treatment of the subject is desired to be performed may be used.

In the present invention, as described above, the shape of the opening surface of the suction tool (1) is adjusted to the shape of the part of the subject to be subjected to the hair growth treatment other than the circular shape, so that there is no need for hair growth. Is no longer sucked, so that adverse effects when the opening surface area is too large or too small can be substantially prevented. However, when the shape of the opening surface is a shape other than a circle, it is preferable to set the maximum inner diameter of the opening surface to be in a range of 5 to 10 cm. This is because if the maximum inner diameter is smaller than 5 cm with a suction tool having a deformed opening surface, the scalp must be strongly sucked in order to sufficiently raise the scalp, and congestion will occur on the scalp.
This is because if it is larger than cm, the scalp bulge itself is less likely to occur.

The inventor of the present application repeatedly conducted experiments using a suction device having an opening surface other than a circular shape. As a result, when a suction device having an opening surface other than a circular shape was used, the maximum inner diameter of the opening surface was 5. By setting to be in the range of 10 cm to 10 cm, these adverse effects can be reliably prevented,
It was found that an excellent hair-growth effect was exhibited. In addition, with respect to a suction tool having an opening surface other than a circular shape, in order to generate new hair growth at a hair loss site, 6 or more capillaries are formed per 1 mm ² , and therefore, the scalp is reduced by 12 mm by suction. It is necessary to raise the above, but the suction condition according to each shape is under intensive research.

If the opening surface (11) has a deformed surface other than a circular shape, the strength of the suction tool is weakened and the suction tool may be damaged by suction. Attaching a reinforcing material such as a woven fabric to the side wall of the opening surface, and covering a circular reinforcing frame made of metal or the like around the outer periphery of the suction tool.
A treatment such as partitioning the inside into an irregular shape with an open surface having a circular cross section may be performed. 13 to 15 show examples in which the opening surface shape is the shape shown in FIG. 9, and FIG. 13 is a diagram showing a state in which a net material (6) is attached to the side wall of the opening surface of the suction tool (1). FIG. 14 shows a circular reinforcing frame (7) on the outer periphery of the suction tool (1).
FIG. 15 is a diagram showing an example in which the inside of the suction tool (1) is partitioned by a partition wall (8) to make the opening surface (11) a modified cross section. In FIG. 15, (9) is an air hole provided not on the partition wall (8) but on the outer peripheral surface of the suction tool (1).

FIGS. 16 and 17 are external views showing another modification of the suction tool (1). The suction tool (1) shown in FIG. In the suction tool (1), a relief valve (14) for releasing a negative pressure state inside the suction tool is provided on the side of the spherical crown (12). Thus, by providing the relief valve (14) for releasing the negative pressure state inside the suction tool in the suction tool (1), a massage effect can be added to the scalp at the time of treatment, and more excellent blood circulation promotion The effect is obtained. That is, first, a negative pressure is applied inside the suction tool (1), the relief valve (14) is opened while the negative pressure is applied, the negative pressure is rapidly released, and then the negative pressure is applied again. By repeating the above, blood can be caused to move in a capillary in the capillary, and the formation of the capillary is promoted. In addition, by combining the configuration of FIG. 16 and the configuration of FIG. 17,
The suction tool (1) provided with the relief valve (14) at two locations may be used.

In the scalp capillary growing apparatus according to the present invention, a plurality of suction tools (1), preferably about 3 to 10 suction tools are provided. In a case where a plurality of suction tools (1) are provided, as shown in FIG. 1, the plurality of suction tools (1) are connected to a vacuum pump (3) via separate hoses (2), respectively. It is preferable that the degree of the negative pressure inside the plurality of suction tools can be individually adjusted by the opening valve (5).
Further, all of the plurality of suction tools (1) may have the same shape or different shapes.

Hereinafter, a method of using the scalp capillary growth device according to the present invention will be described. When using the scalp capillary breeding apparatus according to the present invention, first, the suction device (1) is brought into close contact with the back portion while the subject is laid face down, and the vacuum pump (3) is operated in that state. Then, the inside of the suction tool (1) is brought into a negative pressure state. As a result, the blood capillaries in the back part are dilated, blood circulation in the back is promoted, and blood flow in the whole body of the subject is improved.

In a state where the blood flow of the whole body of the subject is improved by the operation on the back, the suction device (1) is brought into close contact with the scalp at the site where hair growth is to be performed. Then, by operating the vacuum pump (3) in that state, the inside of the suction tool (1) is brought into a negative pressure state for a certain time. This expands the capillaries of the scalp and promotes blood circulation in the head. At this time, since the scalp locally becomes lightly congested, by repeatedly applying this suction action to the scalp, a new capillary can be formed even in a portion where the capillary has already disappeared.

Further, when the inside of the suction tool (1) is in a negative pressure state, the relief valve (14) is opened, the negative pressure is rapidly reduced, the capillary is contracted, and then the negative pressure is applied again to perform suction. Thereby, the piston movement effect of blood can be artificially performed in the capillaries, and the formation of capillaries can be further promoted.

The suction is preferably performed at a negative pressure in the range of 360 to 560 mmHg for about 2 to 5 minutes each time. This is because, if the degree of the negative pressure is too high or the time is too long, blood congestion may become severe, which may hinder blood circulation. In addition, at the time of suction, it is necessary to raise the scalp to 12 mm or more, preferably 12 to 13 mm. This means that if the scalp protuberance is smaller than this, only the number needed for hair growth (1 mm ²
(6 or more per capillaries) cannot be formed on the scalp.

By repeating the above-mentioned treatment once or every several days, blood circulation of the scalp is promoted,
In addition, a new capillary is formed in a portion where the capillary has already disappeared by performing the treatment three to four times. Therefore, hair loss can be prevented, and hair growth can be newly generated in a portion where hair has already disappeared.

By applying a hair restorer to the scalp after performing the above-mentioned treatment, hair growth and hair growth can be promoted more effectively. The type of hair restorer is not particularly limited, for example, calcium pantothenate, vitamin A acetate,
Nutritional supplements such as bantothenyl alcohol, pyridoxine hydrochloride, amino acids methionine, serine, etc .; vasodilators such as α-tocopherol acetate, carpronium chloride, swertinogen (assembly extract); , L
Examples of the hair restorer include one or more stimulants such as menthol and ginseng, and hormones such as female hormones (ethinyl estradiol and estradiol dipropionate).

A hair restorer containing, as an active ingredient, a juice or an extract obtained from a plant of the genus Aloe L. and / or camellia (Camellia japonica) can also be suitably used. Aloe L. plants of the lily family include Aloe arborescens Mill., Cape Aloe (Aloe ferox Mill.), And Socotra aloe.
oe perryi B _AKER ), Curacao aloe (Aloe barbaden)
sis Mill.), Natal aloe (Aloe bainesii T _H)
And the like, but are not particularly limited thereto. Examples of camellia (Camellia japonica) include, but are not particularly limited to, camellia, hornbill camellia, snow camellia, winged camellia, and the like.

[Table 6]

As shown in the results of Tables 4 to 6, φ23 mm
In addition, when a small-diameter suction tool having a diameter of φ37 mm was used, all the subjects could not obtain a scalp ridge of 12 mm or more and the number of generated capillaries of 6 or more in a negative pressure range of 360 to 560 mmHg. On the other hand, φ53m
When a large-diameter suction tool of m, φ55 mm, φ80 mm, and φ83 mm is used, most of the patients receive 360 to 560
Within the negative pressure range of mmHg, a scalp ridge of 12 mm or more and the number of capillaries of 6 or more could be obtained.

In the case of a suction tool having a diameter of 83 mm, since the opening surface does not conform to the shape of the head, the opening surface contacts only a part of the scalp, and the scalp cannot be sufficiently suctioned in many cases. Even when the suction was successful, the scalp was painful due to local strong pressure on the contact site, and the hair root was damaged.

[0050] 2. Hair growth experiment based on the number of capillaries generated Next, for the same six subjects, the number of capillaries per 1 mm ² was 0, 1 to 5, and 6 to 10. Conditions that were, conditions that were 11 to 15,
16-20, 21-25, 2
7 conditions of 6 to 30 were changed to φ53 to 80m
m, suction conditions of 360 to 560 mmHg were set, and a treatment for hair growth was performed under each condition. In the treatment, the suction tool is brought into close contact with the scalp and the vacuum pump is operated, the inside of the suction tool is kept under negative pressure for 2 minutes, and then the release pressure is repeatedly opened and closed by opening and closing the relief valve for 1 minute This was repeated once a week.
The hair growth situation two months after the start of the treatment is shown in Table 7, and an enlarged photograph (200x) of the scalp of the subject E is shown at the lower right of the quadrant photograph of FIG. Photo (200x)
Are shown at the lower right of the quadrant photograph of FIG. The suction condition of the subject E is an opening surface diameter of 53 mm and a suction negative pressure of 460 mmHg, and the suction condition of the subject F is an opening surface diameter of 53 mm and a suction negative pressure of 360 mmHg. In the table, the black circles indicate that hair growth was not observed, and the asterisks indicate hair growth was observed. The marks in the left column have the same meanings as those in Tables 4 to 6.

[Table 7]

From the results shown in Table 7, when the number of capillaries per 1 mm ² is 5 or less, no hair growth is observed in any of the patients, and the number of capillaries per 1 mm ² is smaller. Hair growth was observed in some people only when the number was 6 or more. From this, even if capillaries are formed on the scalp, if the number is 5 or less per 1 mm ^2, no hair growth phenomenon occurs, and in order to cause hair growth, capillaries per 1 mm ² are required. It was confirmed that it was necessary to generate 6 or more.

[0053]

As described above, the scalp capillary growth device according to the present invention is capable of generating new hair growth in a portion of the scalp where the hair has disappeared by sucking the scalp under specific suction conditions. This is a very excellent device that can completely eliminate the troubles of a person with thin hair unlike a conventional device for simply preventing hair loss. When the opening surface of the suction tool is circular, the diameter of the opening surface is 53 to 80 mm, and the negative pressure is 360 to 560 mmHg, it is possible to more reliably form capillary blood vessels to cause hair growth. it can.

If the shape of the opening surface of the suction tool is other than a circular shape in accordance with the shape of the part of the subject to be subjected to the hair growth treatment, the promotion of blood circulation of the scalp and the formation of capillaries are wasted. It is possible to perform the hair growth and hair growth effects in a short period of time. Furthermore,
When the maximum inner diameter of the opening surface of the suction tool is in the range of 5 to 10 cm, a scalp bulge suitable for hair growth and hair growth can be obtained.

In the case where the peripheral shape of the opening surface of the suction device is saddle-shaped and the peripheral edge of the opening surface is formed thicker outward and rounded,
The contact area of the suction tool to the scalp can be reduced, so that when the scalp is sucked, the scalp around the suction tool can be sucked up and raised at the same time, and the suction tool adheres closely to the shape of the head Can be done.
