Abstract

PROBLEM TO BE SOLVED: To enable safe and comfortable beauty culture treatment even in the case of irradiation with laser light for a long time by cooling the surface of the skin to be irradiated with laser light. SOLUTION: A frame-shaped head part 12 protruding a conical surface is integrally attached to the side face of a cylindrical case 11. Concerning the head part 12, a recessed part (a) is formed at the center of the front, for which the top end of the conical surface is notched, and a spherical lens 13 is installed at the deepest part thereof. At the back of the spherical lens 13, a hole (b) is bored and a laser diode LD is inserted and fitted. The base part of the head part 12 is surrounded with Peltier elements 14 as cooling means utilizing the heat absorption phenomenon of thermoelectricity and the outside of Peltier elements 14 is covered with a heat sink 15 for absorbing heat exchanged by the Peltier elements 14. Besides, under the heat sink 15, a fan 16 is installed and the heat sink 15 is cooled. Air blown from the fan 16 can be released by providing air holes on the side face and upper face of the case 11.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a laser cosmetic device for performing cosmetic treatment by irradiating a laser beam from the tip of a probe to be brought into contact with the skin surface.

[0002]

Laser cosmetics irradiates the skin with laser light, separates abnormal pigment cells and removes them as waste and foreign substances, promotes blood circulation and metabolism, and makes the skin beautiful. In addition, laser hair removal irradiates the skin with laser light, causes protein degeneration in the dermal papilla and sebaceous glands, and suppresses hair growth.

[0003] At this time, normal cells around the laser beam may be slightly burned by a photothermal reaction,
You may feel some pain on the skin. As described above, when the skin is irradiated with the laser beam for a long time, the skin is painful, causing a sense of fear or discomfort, causing a sufficient photothermal reaction to the skin and failing to perform an effective cosmetic treatment.

Accordingly, an object of the present invention is to provide a safe and comfortable cosmetic treatment by irradiating a laser beam for a long time by cooling the skin surface to be irradiated with the laser beam. .

[0005]

In order to achieve the above object, the present invention is configured as follows.

That is, in a laser cosmetic device for performing cosmetic treatment by irradiating a laser beam from a tip of a probe which is to come into contact with the skin surface, the tip of the probe is formed of a good heat conductor, and a thermoelectric heat absorption phenomenon is applied to the tip. This is a cooling probe formed by connecting used cooling means.

[0007]

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a longitudinal sectional view of a cooling probe embodying the present invention.

The cooling probe 1 has a cylindrical case 1.
A cone-shaped head portion 12 having a conical surface is integrally attached to one side surface. The head portion 12 has a concave portion a at the center of the front surface where the tip of the conical surface is notched, and a ball lens 13 is installed at the deepest portion. A laser diode LD is inserted behind the ball lens 13 by drilling a through hole b.

The base of the head section 12 is surrounded by a Peltier element 14 as a cooling means utilizing a thermoelectric heat absorption phenomenon, and the outside of the Peltier element 14 is covered with a heat sink 15 for absorbing heat exchanged by the Peltier element 14. Further, a fan 16 is provided below the heat sink 15 to cool the heat sink 15 by air. Ventilation from the fan 16 is provided by providing air holes on the side and top surfaces of the case 11 so as to escape.

The head section 12 is formed of a good heat conductor and is cast of aluminum or an alloy thereof having high heat conduction efficiency.

The cooling probe according to the present invention has the above-described configuration, and when performing a treatment, the head unit 12 is used.
The laser beam is emitted by bringing the tip of the device into contact with the skin surface. At this time, a current having a predetermined direction and magnitude is applied to the Peltier element 14. When an electric current is applied to the Peltier device 14, the head portion 12 is cooled, and the heat exchanged by the Peltier device 14 is absorbed by the heat sink 15 and released to the outside by the fan 16.

[0013]

As described above, in the cooling probe of the present invention, the tip of the probe is formed of a good heat conductor, and a cooling means utilizing the heat absorption phenomenon of thermoelectricity is connected to the probe to cool the skin surface. Therefore, according to the present invention, laser light can be radiated safely and comfortably for a long period of time by preventing overheating of the skin, so that a sufficient photothermal reaction can be caused on the skin and effective cosmetic treatment can be performed. In addition, a pain-relieving effect of relieving pain can be exhibited by cooling the skin. Further, by cooling the skin, an activating effect of activating metabolism can be exerted.
