Device Example 1

Hereinafter, an applicator for a skin care device according to a first embodiment of the present invention will be described in detail with reference to the drawings.

Figure 4 is a side end shaving of the applicator of the skin care device according to the first embodiment of the present invention, Figure 5 is a longitudinal cross-sectional view of the applicator of the skin care device according to the first embodiment of the present invention.

As shown in FIGS. 4 and 5, the applicator of the skin care device according to the first embodiment largely includes a housing 11, a diode laser radiator 12, a transmission member 13, and a pair of electrodes. And a cooling unit 15.

Here, the housing 11 as a whole shows only a portion corresponding to the pistol shape, but in the present embodiment, a pistol shape.

The diode laser emitter 12 is mounted inside the housing 11 to emit a laser. Diode laser emitter 12 emits a laser, for example, at a wavelength of 915 nm. In this embodiment only a portion of the diode laser emitter 12 is shown.

The transmission member 13 is made in front of the diode laser emitter 12 and is made of a transparent crystal. This transmission member 13 becomes a passage of a diode laser.

The pair of electrodes 14 are located on both sides of the transmission member 13 to generate a high frequency. The pair of electrodes 14 protrude slightly further than the transmissive member 13.

The transmissive member 13 and the pair of electrodes 14 are arranged at the tip portion of the applicator, i.e., the portion in contact with the skin surface of the party. Hot spots are formed in the dermis below the epidermis by the high frequency flowing between the pair of electrodes 14 and the diode laser penetrating into the skin through the transmissive member 13, whereby heat energy is concentrated to effectively produce collagen in the dermis. .

The cooling unit 15 is arranged in close contact with each of the pair of electrodes 14 to cool the heat generated by the electrodes 14.

This cooling unit 15 includes a thermoelectric element 15a and a cooling block 15b.

The thermoelectric elements 15a are disposed to be in close contact with the outside of the pair of electrodes 14, respectively, and the wires 115a are connected to the inner ends thereof. The electric wire 115a is connected to a control unit of a main body (not shown).

The cooling blocks 15b are disposed in close contact with the outer side of the thermoelectric element 15a, respectively, and the refrigerant passage 115b is connected to the inner end thereof. The refrigerant passage 115b is connected to a cooling device of a main body (not shown).

Therefore, when the heat of each of the pair of electrodes 14 is transferred to the cooling block 15b via the thermoelectric element 15a, the heat of each of the pair of electrodes 14 is more effectively radiated and cooled more effectively. As a result, the skin of the person is not burned.

In addition, the thermoelectric element 15a is connected to the control unit of the main body so that the control unit adjusts the coolant supplied from the cooling apparatus of the main body to the cooling block 15b so that the temperature of the electrode 14 is accurately controlled.

In addition, the applicator according to the present invention further includes a cap member 23 attached to the tip portion of the housing 11 so as to surround the pair of electrodes 14.

In addition, a flow path 21 is provided inside the cap member 23, which is formed between the pair of electrodes 14 in the cap member 23 and extends rearward.

Meanwhile, the housing 11 is connected to the cap member 23 through the first coupling block 41 and the second coupling block 43.

A female screw portion 23a is formed on the inner circumferential surface of the rear end of the cap member 23, and a male screw portion 41a is screwed to the female screw portion 23a of the cap member 23 on the outer circumferential surface of the first coupling block 41. Is formed.

A first protrusion 41b is formed on the outer circumferential surface of the rear end of the first coupling block 41, and elastically coupled to the protrusion 41b of the first coupling block 41 on the inner circumferential surface of the distal end of the second coupling block 43. The first groove 43a to be formed is formed.

A second groove 43b is formed on the outer circumferential surface of the rear end of the second coupling block 43, and an inner circumferential surface of the front end of the housing 11 is elastically coupled to the second groove 43b of the second coupling block 43. The second protrusion 11a is formed.

In addition, the applicator of the said embodiment is further provided with the red light emitter 31 arrange | positioned obliquely to the side surface of the permeation | transmission member 13. As shown in FIG. The red light emitter may be replaced with a tricolor light emitter that generates any one or more of red light, blue light and infrared light as necessary.

In addition, opposite the red light emitter 31 of the transmission member 13 includes a reflecting member 32 that reflects the red light emitted from the red light emitter 31.

In addition, a space 25 is formed in the cap member 23 to be connected to the flow path 21, and a first through pipe 51 is connected to the space 25 in the first coupling block 41. Is formed, and a second through tube 53 connected to the first through tube 51 is formed inside the second coupling block 43.

The front end of the first through pipe 51 is provided with a hollow plug 51a for guiding the fluid in the space 25 to the first through pipe 51, and the rear end of the second through pipe 53 provides fluid. The extension pipe 53a for sending backward is provided.

The extension tube 53a is connected to a vacuum generator (not shown) separately provided outside the main body or the like.

Therefore, when the vacuum is generated by the vacuum generator, the cap member mounted to the front end of the housing 11 through the second through tube 53, the first through tube 51, the space 25 and the flow path 21. Negative pressure is generated in (23).

In this way, the skin is adsorbed by the negative pressure generated in the cap member 23 and positioned in the space between the pair of electrodes 14.

Therefore, according to the present invention, even when the user of the applicator does not press the pair of electrodes strongly to the skin of the person with great care in view of poor contact state, the skin is located in the space between the pair of electrodes, so that the applicator is used. It is convenient for the user, and even though the curved surface of the target site and the user's pressing pressure are not constant, the pair of electrodes are adsorbed at a constant pressure, so that a poor contact state does not occur, thereby eliminating the spark of RF due to the poor contact state. While safer to use, it can reduce anxiety about the side effects and the discomfort or pain of the subject.

In addition, since the skin is adsorbed between the pair of electrodes 14 and adhered closely, the high frequency energy is sufficiently concentrated to the dermis with low impedance, so that the skin care effect by the high frequency energy and the optical energy can be improved, and the skin is adsorbed. As a result, the secondary massage effect can be achieved.

In addition, the applicator according to the present invention, in place of the red light emitter 31, is disposed obliquely on the side of the transmission member 13 to emit a tricolor light emitting diode capable of irradiating at least one of blue light, red light, infrared light. When replaced with a three-color radiation emitter, the light in the wavelength range close to infrared rays is also called VIOLET. In general, the management of inflammatory acne through photo-stimulation reaction is effective when irradiated with 400-420 nm light in the wavelength range close to infrared rays. .

In this case, it is preferable that the blue light is irradiated with light having a high luminance of high power narrow band 415 nm (narrow band 415 nm of high power). This blue light is close to ultraviolet light, but its width is limited to 410 ~ 420nm, so no ultraviolet light is emitted, which does not damage normal skin tissue.

In addition, the tri-color light emitting diode may emit red light of 630 to 640 nm, and red light having a wavelength of 625 to 645 nm has the best absorption rate to cells and tissues, thereby promoting blood circulation, cell activation, and metabolism, thereby promoting skin Excellent skin care effect by cleansing, soothing and regenerating. In this case, as a matter of course, a reflection member for reflecting one of blue light, red light, and infrared light emitted from the tricolor light emitting diode to the skin side is opposite to the three color light emitting diode of the transmission member of the wavelength band.

Here, when blue light is irradiated to inflammatory acne (P-Acne) that produces an endogenous porphyrin (Por-phyrin) enzyme through metabolism, the corresponding porphyrin enzyme produced by the inflammatory acne absorbs blue light and is formed through a photostimulation reaction. Singlet Oxygen kills bacteria faster than bacterial growth without affecting the surrounding normal skin tissue.

Photodynamic therapy (PDT), or photodynamic reaction, destroys porphyrin enzymes caused by the metabolism of inflammatory acne (P-Acne) bacteria, resulting in singlet oxygenation, which eliminates inflammatory acne bacteria, and red light stabilizes skin tissue. There is an effect close to the color therapy to make, as described above has the effect of calming the excited state of the skin tissue by the high frequency and diode laser.

Here, when the red light is limited to a specific frequency region (630 to 640 nm) among the red light, there is an effect close to the larger color therapy.

In addition, the infrared light irradiated from the tricolor light emitting diode penetrates into the skin tissue and causes a thermal reaction, thereby stimulating mast cells and giant cells, thereby helping to regenerate the cells, thereby increasing the regeneration effect by enhancing collagen and elastin resynthesis. It is effective in improving wound regeneration, fine lines and pigmentation. At this time, the infrared light emitted from the tricolor light emitting diode is preferably a wavelength within 800nm to 900nm.

As the blue light, red light and infrared light are irradiated to the affected area in order to care for the skin, the blue light sterilizes the affected area, and the red light soothes the affected area through the sterilization process. Perform a series of processes to play.

Here, the site to be used receives a series of processes in which blue light (sterilization), red light (calm), and infrared light (regeneration) are sequentially irradiated for a certain period of time, thereby achieving skin care effects corresponding to many color therapies. .

Device Example 2

Hereinafter, the applicator of the skin care apparatus according to the second embodiment of the present invention will be described in detail.

Figure 6 is a longitudinal cross-sectional view of the applicator of the skin care device according to a second embodiment of the present invention.

As shown in FIG. 6, the applicator of the skin care apparatus according to the second embodiment includes a housing 100, a single electrode 110 disposed inside the housing 100 to generate a high frequency wave, and One end is coupled to the housing 100, and a through hole 121 is formed at the other end to be in close contact with the skin of the subject. A portion of the electrode 110 is inserted between the one end and the other end and the through hole 121 is formed. An inner space 122 is formed to be connected to the inner space 122, and includes a cap member 130 having a flow path 125 connected to a vacuum generator that provides a negative pressure to the inner space 122.

Here, one electrode 110 (Unipolar) is capable of managing wrinkles and cellulite by transferring energy to a deeper portion of the skin using electromagnetic waves than a pair of electrodes (Bipolar).

That is, the skin is adsorbed by one electrode (unipolar) 110 by the negative pressure generated in the cap member 130 and adheres to the electrode 110 so that the high frequency energy is delivered intensively deeply into the dermis, thereby improving the skin care effect by the high frequency energy. As the skin is adsorbed, the secondary massage effect can be obtained.

In addition, the flow path 125 includes a filter 127 for preventing foreign substances from being sucked into the vacuum generator side of the subject's skin.

In addition, the housing 100 is provided with a cooling unit 140 for cooling the heat generated from the electrode 110, the cooling unit 140 is a cooling block 142 and the cooling block 142 surrounding both sides of the electrode. It includes a thermoelectric element 145 for absorbing the heat of the heat dissipation to the outside.

At this time, when the thermoelectric element 145 is supplied with power, one side of the thermoelectric element 145 cools the heat generated by the electrode 110 through the cooling block 142, and the other side portion emits heat absorbed. There is no fear of an image by the electrode 110, and the heat transferred to the other surface part may be discharged to the outside through the housing 100.

Now, the driving method of the applicator of the said skin care apparatus which concerns on this invention is demonstrated. Also, the skin care device according to the present method also includes a housing 11, at least one electrode disposed inside the housing 11 to generate a high frequency, and one end coupled to the housing 11 and the other end to the subject. A through hole 16 is formed in close contact with the skin, and a portion of the electrode 14 is inserted between the one end and the other end, and includes a suction means connected to the through hole 16.

Moreover, if necessary, the skin care device further includes a cooling device for cooling the electrode, or a diode laser emitter 12 emitting a near infrared laser of 800-1000 nm, and in front of the diode laser emitter 12. It may further include a transmission member 13 disposed to transmit a laser.

7 is a photograph of a state of applying to the skin using the apparatus according to the present invention. This will be described schematically with each step with reference to FIGS. 8 to 10.

First, as shown in Figure 8, (a) after the suction step of inhaling a part of the subject's skin into the through hole by the suction means, (b) cooling the epidermal part through the electrode to about 0-10 ℃ After the cooling step, as shown in Figure 9, (c) laser irradiation irradiating the 800-1000nm near infrared laser emitted by the diode laser emitter 12 to the subject's skin through the transmission member (13) The steps are taken. As described above, the near infrared laser is most preferably a near infrared laser in the vicinity of 915 nm. This is because the laser light of 915 nm wavelength has a maximum skin penetration effect of 2.5 mm, as the skin penetration depth is most effective, as shown in FIG.

However, considering only the skin penetration effect, as shown in Figure 14, the most penetrating power in the wavelength band of about 475nm, in this case, because the side effect to the human body is concerned in the ultraviolet wavelength band, 915nm wavelength band with good penetration in the near infrared wavelength band Laser light is used.

Finally, as shown in Fig. 10, (d) the skin care according to the present invention is performed by performing a high frequency radiation step of performing suction by the suction means and conducting a conductive high frequency stimulus of about 1 MHz to the subject through the electrode. It is over.

Therefore, according to the present invention, as shown in FIG. 11, the pneumatic effect, the cooling effect, the optical effect, and the harmonic stimulating effect cause synergistic effects, thereby maximizing the skin care effect.

That is, as shown in Figure 12, a part of the skin is embedded between the electrodes by the step of inhaling the skin, although the effect of removing sebum, etc. only by the inhalation step, it does not have a great meaning in itself, the inhalation state When irradiating the conductive RF radio frequency while moving the skin care device in, even if the device is not pressed strongly to the skin to compress the skin, the regeneration of elastin or collagen, which is desirable for skin remodeling, can form deep into the skin. Furthermore, since the liquid blood is collected by the inhalation step to the site where the applicator is to be used, the effect of laser irradiation in the next step is further increased because it accelerates the focusing and induction of the chromophore.

In addition, due to the cooling effect of cooling the electrode and eventually cooling the epidermis of the skin at the same time as the inhalation step, the epidermis maintains a low temperature and has high skin resistance, and the dermis has a high temperature and has low skin resistance. When irradiating the RF radio frequency, a lot of RF radio frequency flows to the dermis, so that the skin can be regenerated in a desired direction in the deeper part of the skin, and the risk of burns due to overheating of the epidermis can be prevented.

In particular, when the near-infrared laser irradiation is performed in the next step, since the chromophore in the inhalation step is formed deep in the skin (at the depth through which the blood vessel passes), the area where the chromophore is formed during the laser irradiation is intensively heated further. Since hot spots are formed deeply, the low skin resistance at the site can further concentrate the RF irradiation effect.

Fig. 15 shows the results of comparative experiments under the same conditions when high frequency irradiation is performed in the skin inhalation state (a) and when RF irradiation is performed on the skin without it (b). The effect on the epidermis is small when the radiofrequency irradiation is performed in the inhaled state, which indicates that the deep skin effect appears when the radiofrequency irradiation is performed in the skin inhalation state.

FIG. 16 shows a case where RF irradiation (20 times at 100 J / cm 2) is performed on the skin of a subject under inhalation after all the intake, cooling (5 ° C.), and laser irradiation (50 J / cm 2) steps are performed on the meat which is the test object. (a), otherwise RF irradiation is performed in a state in which the skin care device according to the present invention is simply in contact with the skin (b), and RF irradiation is performed in a state where the skin care device according to the present invention is separated from the skin by about 2 mm. (C) is a photograph of the epidermis of the test subject. It can be seen that hemoglobin is much clearer in the case of (a) according to the present invention than in the case of contacting the skin (b). When the skin care device is separated from the skin (c), it can be seen that the skin whitening phenomenon may adversely affect the skin.

17 is a photograph of the cut meat in the experiment of the three cases. It can be seen that the stimulation was applied deeper to the skin in the case of (a) according to the present invention than in the case of contact with the skin (b), and in the case of separating the skin care device from the skin (c), It can be seen that the bleaching phenomenon has adversely affected the skin.
