【Example】

 An embodiment of the photo epilation probe according to the present invention is shown in the drawings, and the photo epilation device according to the present invention will be described in more detail. FIG. 1 shows an optical hair removal probe 10 according to the present invention. The photoepilation probe 10 is composed of a tip portion 12 that is brought into close contact with the site of the skin to be epilated, and a main body grasping portion 14 that can be held by one hand following the tip portion 12, and an external control device (not shown) for controlling the photoepilation probe 10 is shown. No.) and a cable 16 mounted between the probe.

FIG. 2 shows the tip portion 12 of the photo epilation probe in cross section. A cosmetic treatment is performed by contacting a portion of the skin to be hair-removed on the upper side of the head body 24 attached to the tip of the body grip portion 14. The condenser lens 22 is mounted in the through hole 29 on the axis of the head body 24. The far infrared ray emitting section 20 is arranged adjacent to the periphery of the condenser lens 22. Further, in the case of this embodiment, an exhaust port 28 for adhering the skin to the upper surface of the head body 24 by vacuum exhaust is provided in a part of the head body 24, and a screw thread is provided on the side portion of the head body 24. There is a sleeve 26 that is movable in the axial direction of the head body 24 via M. By the movement of the sleeve 26, the contact distance between the upper end surface of the sleeve and the upper surface of the head body 24 can be adjusted. The sleeve 26 is made of a transparent or translucent material so that the portion of the skin to be depilated can be identified. A board (preferably a printed circuit board) 34 can be fixed inside the head body 24, and a laser diode 30 and a light emitting diode 32 are mounted on the board 34. The laser diode 30 is arranged directly below the condenser lens 22 and emits the emitted light to the skin to be hair-removed through the condenser lens 22. The light emitting diode 32, which is arranged immediately beside the laser diode 30, emits visible light and is used to confirm the operation of the laser diode 30. In the case of this embodiment, the laser diode 30 emits near-infrared radiation having a wavelength of the main component light emitted of about 785 nm and an output of about 40 mW. However, the operation of this laser diode 30 cannot be visually confirmed. Therefore, when the laser diode 30 is turned on, the light emitting diode 32 is also turned on at the same time, and the visible light emitted from the light emitting diode 32 through the condenser lens 22 is exposed to the outside, that is, the head 12. Check the operation status of the laser diode 30 by checking from the tip. Further, the board 34 is mounted with a printed board connector for supplying power to the far infrared ray emitting section 20 via the conductor L.

In the case of this embodiment, the cable 16 connected to the other end of the grip body portion 14 is an electric wire (not shown) for sending predetermined power to the laser diode 30, the light emitting diode 32 and the far infrared ray emitting portion 20. ) And a flexible suction conduit (not shown) for vacuum suction. The electric conducting wire is connected to the substrate 34 via a connector therein, or directly attached.

The basic structure of the photo epilation device according to the present invention is described in detail in the above-mentioned Japanese Patent Application No. 8-109, except for the configuration for emitting far-infrared radiation proposed here. Therefore, the detailed description is omitted. In particular, those corresponding to the exhaust port 28 and the sleeve 26 are used based on the same principle as the invention of this prior application. Although only the exhaust port 28 is shown in FIG. 2, an exhaust pipe is actually connected to the exhaust port 18, and the exhaust pipe is connected to an external control device through a cable 16 together with an electric wire.

The far infrared ray emitting portion 20 has a three-layer structure as shown in FIG. 3A, and has a donut shape as shown in FIG. 3B. There is a gap 45 for electrically insulating the donut body by separating it from each other, and both ends of the gap 45 are provided with energizing terminals T for connecting to the conducting wire L. The terminal T is connected to a film heater 46 formed of an electric heating material, mainly a metal coating of a nichrome-based material, and a black thin carbon film 44 is vapor-deposited on the film heater 46. A transmission layer 42 for efficiently transmitting far-infrared radiation to the upper part (the skin to which it is in contact) and for reducing reflection from the skin is in close contact therewith. For the transmission layer 42, a synthetic resin having a high transmittance for far infrared radiation, for example, an ABS resin is suitable, and its thickness is about 1 to 3 mm. The black carbon film 44 has a thickness of several μm, and the film heater 46 has a thickness of 1 mm or less.

In the procedure of using the photo epilation device according to the present invention, first, the epilation wax or the like is applied in advance, and then the epilation hair is mechanically exfoliated by adhering the hair to be epilated to the adhesive tape or the like. In this state, the living tissue of the hair root is still alive, so if it is left as it is, the hair will grow again. Near-infrared laser excitation light with high coherence is used to kill the living tissue of the hair root. Although the output of the laser light used is kept relatively low, this laser excitation light puts a great burden on the body, so heat is applied to the treated skin area to calm the biological tissue and at the same time enhance its activity. Therefore, far infrared radiation for raising the temperature is applied. The application of far infrared radiation may be performed before or after the application of the laser light of near infrared radiation used for the original hair removal, or independently. It is effective to prepare a function corresponding to the attached external control device and its function switching mode so that such an operation can be performed.

Further, in the embodiment described here, a vacuum suction device is provided in order to bring the skin into close contact with the tip surface of the head 12 of the photoepilation probe 10, but a device without any suction device is also conceivable. . Such devices are suitable for use where the skin is relatively hard and difficult to bend. Of course, in such a case, the optical hair removal probe does not need the height or interval adjusting sleeve 26, the attached thread M and the exhaust port 28, and the attached external control device is equipped with a vacuum exhaust system. do not have to.

Although the condenser lens 22 is a condenser lens in the embodiment shown in FIG. 2, this portion is an optical material capable of transmitting the light of the laser diode 30 contained therein to the outside (skin side). (For example, optical components such as simple glass and quartz) can also be used. In that case, it is important that the light from the laser diode 30 and the light emitting diode 32 can be efficiently transmitted to the outside (that is, light loss is minimized).

The above description has been presented primarily with respect to only one preferred embodiment. It is conceivable to modify or modify the configuration of this embodiment. However, all the configurations defined in the scope of claims for utility model registration are within the scope of this invention.

[0018]

[Effect of device]

Therefore, the burden on the body can be reduced by raising the temperature of the desired site by preheating, and the destruction / alteration of living tissue can be promoted efficiently.
