The present invention relates to a cosmetic device for performing cosmetic treatment by removing the epidermis on the skin surface that has scars.

[Conventional technology]

Problems associated with a series of unsightly conditions that occur on the skin include acne scars, enlarged accidental or surgical scars such as keloids, pigmentation (spots), and stretch marks, which are typically linear spots. Traditionally, this type of disfigurement involves mechanically, chemically, or electrically removing the skin surface in a controlled manner (exfoliation).
method has been used. In particular, there is an electrical method in which laser radiation is applied directly to the skin, but this method has the disadvantage that the alteration caused by the radiation reaches from the surface to the inside, destroying healthy internal skin cells, the so-called dermis.

In addition, in the chemical peeling method, a beauty treatment cream, for example, is applied to the surface cells of the skin, the so-called "epidermis", and the skin tissue is chemically destroyed and peeled off. . Even in this case, it is difficult to know the extent to which the destruction has progressed, and it is necessary to interrupt the process midway through, and it is necessary to constantly repeat the operations of wiping off the cream and rinsing it away. There are significant individual differences in side effects, as some people have allergies. In any case, this chemical reaction is more or less violent, painful, and in many cases
Part of the skin must be anesthetized.

Further advantageous developments according to the invention are specified in the dependent claims.

[For production]

In the cosmetic device according to the present invention, a probe is selectively applied to a desired skin region to perform treatment, and peeling of the skin can be visually observed in stages. Disinfected and dry microcrystalline particles, primarily aluminum hydroxide, are applied to the skin using a vacuum to create a soft exfoliation. Additionally, damaged skin cells (dermis) are ideally regenerated.

〔Example〕

This invention will be explained in more detail below based on the drawings.

FIG. 1 schematically shows the overall configuration of a beauty device according to the present invention, which includes an air pipe for spraying beauty powder onto a desired skin area 20, a powder storage tank, and a powder storage tank. A main body 10 having a transportation drive unit, etc., a probe S, and a conduit CI connecting the two.

It is composed of C2.

The powder storage tank T1 for spraying that is installed in the main body 10 of the apparatus is, for example, a transparent plastic container that allows the powder MP1 for spraying inside to be easily seen from the outside.
There is a lid on the top to take things in and out. Storage tank T
An inlet port L1 for air piping is provided at the bottom of 1.
It communicates with the inside of the storage tank T1 via the filter F4. For discharging, a flexible synthetic resin, for example, vinyl chloride pipe is discharged from the connection part of the main body 10 via the discharge port O1, which communicates with the lower end of the hollow pipe I whose upper opening is located in the upper space of the storage tank T1. The probe S located outside the main body 10 is reached via the introduction conduit CI.

The details of the probe S will be described in detail later, but the powder that hits the skin 20 pressed against the tip of the probe S reaches the inlet L2 of the recovery tank T2 via the discharge conduit C2.

Cosmetic powder obtained by scraping the surface of the skin 200 and a part of the scraped skin are introduced here together with the exhausted air.

The introduced powder MP2 remains at the bottom of this storage tank T2. The outlet 02 of the storage tank T2 is equipped with a filter F2.
This discharge port 02 communicates with the vacuum piping side. Even in this case, it is advantageous to use transparent plastic or glass for the side surface of the storage tank T2, since the inside can be visually observed.

The vacuum piping side is constantly evacuated by a vacuum pump P1 consisting of, for example, a rotary pump or a simple Roots pump. The vacuum degree of this piping can be determined by the opening degree of a manual or semi-fixed vacuum regulating valve VR2 that can vary the flow rate continuously or stepwise.

That is, if the opening degree is large, a larger amount of external air is introduced into the vacuum piping, so the vacuum pressure increases, and conversely, if the opening degree is small, the vacuum pressure decreases. Vacuum regulating valve VR
2 and the atmosphere side is equipped with a filter F3 for removing dust.

Furthermore, it is convenient if this vacuum piping is equipped with a vacuum gauge 01 for measuring pressure. In addition, as will be explained in detail later, this vacuum piping communicates with the pressure piping side via a three-way valve (2) which is preferably electromagnetically controlled. This three-way valve V
2 is the discharge port 02 on the pressure system side or the vacuum pump P1
used to switch to either side.

The inlet side of the powder storage tank Tl consists of a filter F1 connected in series, a manual variable flow rate regulating valve VRI used to adjust the powder spraying speed, and a three-way valve (1) which is preferably electromagnetically controlled.

Direction valve (1) is used to introduce compressed air to the pressurizing system described above when the powder spraying speed is to be made faster than that controlled by negative pressure. In other words, since normal beauty treatment is performed by suction, the three-way valve ■1 connects the inlet L1 to the control valve VRI side, but in order to introduce compressed air to increase the beauty treatment speed, it is connected to the pressure system side. Connect.

In the configuration of the device according to the invention, the air sucked from the discharge side of the probe S is drawn to the vacuum pump P1 via the collection tank T2. Therefore, if the opening 44 of the probe is not in close contact with the skin 20, the atmosphere will be introduced through this opening 44, and no force will be generated to suck the air on the introduction side of the probe.

Therefore, the powder MPI in the storage tank T1 cannot be drawn out to the discharge side. After all, when the probe S is removed from the skin 20, the beauty treatment is interrupted. Naturally, if the probe S is brought into close contact with the skin 20, the suctioned air will further suction the cosmetic powder in the storage tank T1 from the probe S through the conduit C1. In that case, the discharged air is introduced into the inlet L1 at the bottom of the storage tank T1, and the air introduced further passes through the cosmetic powder MPI deposited in this storage tank T1, and on the one hand from the upper space of the hollow pipe H through the upper opening of the hollow pipe H, and on the other hand from the pore located in the part connected to the lower part of the hollow pipe H and buried in the powder MPI to this hollow pipe H. Introduced, outlet 0
1 and reaches the probe S via a flexible conduit C1. At this time, powder M P is present in the pores of the hollow pipe H.
There are numerous pores that allow the microcrystals of 1 to pass through. Therefore, the microcrystalline powder is drawn out together with the invading air.

Furthermore, the device according to the invention can be used without a pressurization system. That is, since beauty treatments can be performed using only the suction force of air, in principle, it is not necessarily necessary to provide additional support with a pressurizing system. In the case of such a configuration, it is possible to simply form the three-way valve without using the two three-way valves Vl and V2 and make it independent of the pressurizing system, and in some cases, the pressurizing system can be completely eliminated. Can be removed.

However, one of the benefits of adding a pressure system is that it is effective in increasing the speed of beauty treatment, especially for people with extremely hard skin. can be increased. Other usefulness is filter F5 and/or
Alternatively, it can be used to prevent clogging of the filter F4. In particular, since the powder used is fine, it is possible to prevent the filter from becoming clogged and the spraying speed to decrease, thereby preventing deterioration of the beauty treatment. Therefore, in order to prevent clogging, it is effective to apply compressed air to the filter periodically at fixed time intervals, or irregularly but fairly frequently. In the latter case, it is particularly advantageous to configure the electric circuit to automatically switch the three-way valve 2 to the pressurizing system for a few seconds when the pressurizing system is turned on, for example. It is effective to apply compressed air to the filter F5, which is most likely to be clogged, in the direction opposite to the flow direction of the airflow during blowing, that is, the direction opposite to the direction in which the air flows out from the storage tank T2.

The remaining component not illustrated in FIG. 1 is the pressurization system used to introduce compressed air into the evacuation system described above. The compressed air is formed by a compressor FO,
It is stored in a buffer tank T3 via an electromagnetically driven pressure regulating valve 4.

The compressed air is communicated from this tank T3 to the connection side piping in which the two three-way valves Vl and V2 mentioned above are arranged via the filtering device FA and the manually operated pressure regulating valve VR3. Buffer tank T3 is normally 8 by pressure regulating valve V4.
It is constantly maintained at ~10 atm, and variably adjusted in the maximum range of O~6 atm by the pressurization regulating valve VR3 on the side where it is finally extracted.

In that case, it is advantageous to equip the pressure gauge G2 on the discharge side.

FIG. 2 schematically shows the detailed structure of the probe S of the beauty device according to the present invention. The probe S is composed of a probe body 30 and a cap 40 that is detachable from the probe body. The probe body 30 has an introduction passage 32 for introducing the air to be conveyed and a discharge passage 34 for discharging the air, each of which has one end connected to a corresponding flexible synthetic resin conduit C.
Connected to I and C2. The other end is this probe body 30
It communicates with a hollow space 46 formed by the cap 40 and the cap 40 . In order to improve the adhesion of the probe to the skin and to effectively discharge the used powder, it is advantageous for the inner diameter of the discharge passage 34 to be larger than the inner diameter of the introduction passage 32.

In addition, in order to effectively apply the powder to the skin, the introduction passage 3
The end of the hollow space 46 side of 2 faces the opening 44,
It is effective if the end of the discharge passage 34 on the hollow space 46 side is separated from the opening 44.

The cap 40 is preferably made of metal 1 2 which is stable against abrasion and polishing. An opening 44 for cosmetic treatment is provided near the tip of the cap 40. When the opening 44 at the tip of the probe S is brought into contact with the desired skin, the probe is suctioned by evacuation and comes into tighter contact with the skin 20. At the same time, the air and cosmetic powder introduced from the introduction passage 32 are sprayed, hit the skin 20, and are reflected. The reflected powder and particulate tissue generated from the scraped skin surface are transferred together through the exhaust passage 34 to the collection tank T2. Exfoliation of skin tissue should be limited to the epidermis only. A good guideline is to exfoliate down to the basic layer between the epidermis and dermis. When the detachment reaches this basic layer, congestion is seen. Care must be taken because if the abrasions penetrate into the dermis, it will cause bleeding and pain.

Since it is effective to vary the opening area of the opening 44 depending on the size, shape, and site of the target skin, it is advantageous to prepare a plurality of caps 40 having different opening areas. Alternatively, it is also possible to use a slit (not shown) system in which the opening 44 can be changed continuously.

Cosmetic powders are stable against heat, light, humidity, shock, etc.
Suitable are microcrystalline particles of substances that are not harmful to the human body, such as metal oxides, hydroxides, etc. (preferably aluminum hydroxide). Moreover, when it hits the skin, it should have a mass that transmits enough momentum to peel off the epidermis of the skin, and be small enough to be sprayed into dust by the exhaust system, with a particle size of several tens of μm. ~ several μm is effective.

〔Effect of the invention〕

The remarkable advantage obtained by the cosmetic device according to the present invention is that the dermis can be safely and reliably exfoliated without using advanced techniques and experience, and the exfoliated epidermis is regenerated by natural healing power. Furthermore, since there is no pain during the treatment, there is no need for anesthesia. Conventional methods can easily treat cosmetic treatments such as acne scars, enlarged accidental or surgical scars such as keloids, pigmentation (stains), and stretch marks, which are typical of linear spots, which are associated with side effects and a heavy mental burden. , and can be done reliably.
