Problems to be solved by the invention

[0004] The problems to be solved are the points 1 to 8 described above, and an object of the present invention is to provide a device capable of performing treatment at the same time as providing superior operability by miniaturizing a conventional device. Means for solving the problem [0005] In order to achieve the object of the present invention, an observation window is provided in the head part of the probe that can be held and operated by hand, and the observation window is applied to the skin to close the opening surface with the skin. A compact camera that forms a dark room, illuminates the dark room with ultraviolet light, purple light, blue light, or white light and emits at least one or more of its power, and the skin illuminated by this light source In addition, a monitor capable of magnifying observation that displays images taken by this small camera in real time is provided, and at least one of laser irradiation, iontophoresis, ultrasonic beauty, low-frequency beauty, tapping, or photo irradiation is provided. There will be one or more treatments.

The invention's effect

[0006] In the present invention, since the probe can be held and operated, the observation window, which is easy to use, is closed with the skin to form a dark room in the head, so that a conventional large dark room or dark curtain can be omitted. Also, don't put your face in the darkroom! / So you can observe your own skin.

In addition, since the visible light is irradiated, the brightness of the observation image is increased by about 6 to 10 times, and the observation screen is bright. Therefore, the light receiving sensitivity is increased, and the cooling device for the CCD camera can be omitted.

Also, purple light and blue light are harmless to the skin and can be observed for a long time.

In addition, since a monitor capable of magnifying observation is provided, a small part of the skin can be observed.

In addition, treatment means are provided so that treatment can be performed simultaneously with observation.

BEST MODE FOR CARRYING OUT THE INVENTION

Hereinafter, embodiments of the present invention will be described.

[0008] FIGS. 1 and 2 show an example of a treatment apparatus that combines laser irradiation and ion introduction for skin observation.

In the treatment device, a main head 1 used for skin observation and laser irradiation is formed so as to protrude in front of the probe P, and a sub head 2 for ion introduction is formed on the back side thereof facing backward.

The probe p has a power switch S1 on the front side, a laser light irradiation switch S2 and an illumination light switching switch S3 on the side surface, and an ion introduction start switch S4 on the opposite side surface. Cover the tip of the main head 1 with an insulating cylindrical cap c such as a plastic molded product, and use the tip opening of the cap C as the observation window W to be in contact with the skin. Attach three skin contact terminals T of the touch sensor to the circular opening edge of the observation window W at intervals of 120 degrees. Terminal wiring is not shown.

Cap C and head 1 can be attached by screw type (see screw 15 in Fig. 3), notch type, panel type, etc., and cap C can be moved back and forth with respect to head 1.

[0009] The sub head 2 has a cylindrical shape, and an electrode E1 for ion introduction is attached to the tip surface thereof, and the other electrode E2 that makes a pair with the electrode E1 is attached to the side surfaces on both sides of the probe P.

In the case of a treatment device that performs ultrasonic beauty instead of ion introduction, an ultrasonic transducer with piezoelectric ceramic force is installed inside the secondary head 2, and the start surface of the secondary head 2 is moved by operating the start switch S4. Vibrating and performing ultrasonic beauty.

For a low-frequency beauty treatment device, attach the low-frequency beauty electrode E1 to the tip of the secondary head 2 and the other electrode E2 to the sides on both sides of the probe P, and attach the tip of the secondary head 2 to the skin. Operate the start switch S4 in the state where it is placed on and apply low-frequency beauty.

In the case of a tapping treatment device, a vibration motor is installed inside the sub head 2, and the tip of the sub head 2 is vibrated vertically to tap the skin and penetrate skin lotion deeply.

FIG. 3 shows a cross-sectional view of the main head 1.

A small camera 11 is installed in the inner part of the main head 1 with the front facing forward, and a plurality of blue LEDs 12a (center wavelength) are placed in front of the small camera 11 along the same circumference centered on the axis of the small camera 11. 470nm) and white LED 12b are arranged alternately.

As a result, the light of the blue LED 12a and / or the white LED 12b is radiated from the periphery of the small power camera 11 at all angles to the observation window W, so that the skin surface and the inside interfere with the reflected light of the LED. It can be observed three-dimensionally. Reference numeral 16 denotes a lens barrel of the small camera 11. The focus is adjusted by moving the cap C back and forth with respect to the main head 1 and changing the distance between the small camera 11 and the observation window W. It is also possible to fix the cap C and use a structure that allows the small camera 11 to move the lens back and forth instead! ,. With such focus adjustment, the inside of the skin is observed with the focus during skin observation slightly deeper (inside) than the skin surface.

Here, if the wavelength range of the blue LED 12a is wide, the captured image will be deeper than the single wavelength light.

Next, the semiconductor laser 14 is attached in a direction intersecting with the axial center line (optical axis) of the small camera 11. Reference numeral 13 is a mounting base for the semiconductor laser 14, and wiring for supplying power is applied thereto.

The laser irradiation intensity is adjusted by blinking the semiconductor laser 14 in a pulsed manner and changing its on-time. In the strongest case, it is for hair removal, and the hair root is damaged by laser light to prevent hair regeneration. When the on-time is shortened, the irradiation intensity is weakened and the skin treatment effect is obtained. For example, melanin, the causative agent of skin spots, is burned away by weak laser irradiation.

When performing photo irradiation instead of such laser irradiation, various LEDs are appropriately installed on the main head 1. In that case, the irradiation switch S2 is operated to irradiate photo light instead of laser light.

For example, blue LED light (blue light) has a peak wavelength of 465 nm and a luminous intensity of, for example, 70 to 200 mcd. This blue light is well absorbed by hemoglobin, so it is effective for redness and reddishness. As a color effect, it increases lymph drainage and blood circulation. Furthermore, the effect etc. which relieve stress and tension can be acquired.

In the case of a green LED, for example, the peak wavelength is 522 nm and the luminous intensity is 140 to 560 mcd, for example. This green light has higher skin penetration than the above-mentioned blue light, so it is absorbed by hemoglobin in the deep dermis and is effective for red leather in the deep dermis. The effect of color is suitable for improving dry skin and removing spots due to sebum and pigmentation. In addition, a mental and physical relaxation effect can be obtained.

Yellow LED light (yellow light) has, for example, a peak wavelength of 592 nm and a luminous intensity of, for example, 220 mcd. This yellow light has a higher skin penetration rate than red light and orange light, and is therefore effective for spots on the skin surface. In addition, it is suitable for improving aging skin and troubled skin as a function of color. The light of the orange LED (orange light) has a peak wavelength of 609 nm, for example, and a luminous intensity of 2 OOmcd, for example. This orange light is absorbed by melanin 'hemoglobin and is effective for brown spots. In addition, the effect of color is important to improve oily or millet skin and to optimize metabolic function.

Furthermore, the red LED light (red light) has a peak wavelength of, for example, 641 nm and a luminous intensity of, for example, 180 mcd. This red light responds to melanin in the deep part of the skin where the skin penetration is high, and is effective for stains deep in the skin. Also, combined with red color action, it is suitable for improving reddish skin, and can promote blood circulation and the like. It is also suitable for so-called slimming care.

For example, the infrared wavelength of the infrared LED has a peak wavelength of 870 nm (and 940 nm). This infrared ray is effective in increasing collagen because it reacts with water, melanin, and hemoglobin in the deep dermis. Specifically, this infrared ray has a fibroblast activation effect, and can effectively produce new LV and collagen.

In this way, there are specific effects depending on the wavelength range of the LED, so if necessary, combine LEDs with two or more wavelength ranges to perform appropriate photo irradiation.

FIG. 4 shows a configuration diagram of an image display system that displays a photographed image of the small camera 11.

In the image display system, the small camera 11 receives the light from the lens with a CMOS or CCD and inputs the image signal to the controller 3, which controls the brightness, contrast, color balance, etc., and outputs it to the monitor screen 4. .

By controlling the brightness of the captured image, the reflected light of the internal force of the skin can be enhanced, and an easy-to-see observation image can be acquired.

The image signal can be converted into a digital signal and input to the personal computer 5 for image processing such as color correction and resolution change.

[0014] The small camera 11 can be switched in magnification, and can switch between three types of lenses of 10 times, 25 times, and 50 times.

This makes it possible to observe a wide area of the skin or to zoom in on a small part of the skin in detail by increasing the magnification.

In magnified observation, instead of replacing the lens with a higher magnification, the image data input to the PC 5 Data zooming may be performed by a method such as digital zooming.

[0015] For example, the stain has a size of several millimeters or more, and the high magnification magnification observation of about 50 times captures the stain on the entire observation screen, so it is impossible to determine the boundary between the stain and the surrounding area. Become.

Therefore, it is desirable to set the magnification to 10 times or 25 times so that, for example, an area of about 9 X 12 mm can be observed.

At the same time, it is also necessary to observe the strength and part of the screen, so that the magnification can be switched.

[0016] The treatment apparatus embodying the present invention is configured as described above. First, the power switch S1 is pressed to turn on the power. As a result, the white LED 12b in the head 1 is turned on. Next, the probe P is held in the hand and the observation window W of the head 1 is pressed against the skin. Thereby, the photographed image of the small camera 11 is displayed on the monitor screen 4.

At this time, the magnification of the small camera 11 is switched as necessary.

Also adjust the brightness, contrast, color balance, etc. of the monitor screen 4.

Here, when the illumination light switching switch S3 is pressed, the white LED 12b is turned off and the blue LED 12a is turned on instead, and the skin of the observation window W is irradiated with the blue light. As a result, the internal state of the skin that could not be seen with white light is displayed on the monitor screen 4. In this case, the light of the blue LED 12a does not hit the skin perpendicularly, but is applied at an angle from the surroundings, so the reflected light of the skin force does not enter the camera 11 and a clear image is obtained. It is projected in three dimensions. When blue light is used in this way, the internal state of the skin can be observed in the same way as ultraviolet light.Next, when switch S3 is pressed again, blue LED 12a turns off and white LED12b turns on instead. Then, the condition of the surface of the skin that cannot be seen is displayed on the monitor screen 4.

By switching between blue light and white light in this way, it is possible to observe while comparing the state of the inside and the surface of the skin.

[0018] Next, while looking at the monitor screen 4, move the probe P, and simultaneously press the switch S3 to observe the monitor screen 4 while switching the white LED 12b and the blue LED 12a on and off, When the spot to be irradiated with the laser is found, press the irradiation switch S2 to turn on the semiconductor laser 14. At this time, the touch sensor is not turned on unless all three terminals T around the observation window W are in contact with the skin, and the laser light is not irradiated unless the touch sensor is turned on. This prevents the danger of laser light entering the eyes.

In addition, when a location where ion introduction is to be found is found, the electrode E1 at the tip of the secondary head 2 is pressed against the skin and the ion introduction start switch S4 is pressed.

As a result, a direct current flows between the hand in contact with the electrode E2 of the probe P and the skin such as the face in contact with the electrode E1 of the head 2, and the iontophoretic treatment is performed.

The blue light of the blue LED12a is not limited to skin observation, but also has a facial effect that calms the hot flashes on the skin.
