Description

[DESCRIPTION] [Invention Title] LASER HAIR-LOSS TREATMENT DEVICE 5 [Technical Field] The present invention relates to a laser hair-loss treatment device that treats or prevents hair-loss by simultaneously supplying low-output laser and vibration 10 stimulation to the scalp of a human body, in more detail, a laser hair-loss treatment device that can contribute to growing hairs and preventing hair-loss by activating the hair-root cell of the scalp, by using optical pulse of laser diodes, vibrating elements, and heat-emitting 15 elements, and increase productivity and efficiency in radiation of laser by simplifying the structure. [Background Art] In general, although the exact reason for hair-loss is 20 not known, it is known that the hair-loss is because of hereditary factors and influence of male sex hormones and stress. Although the male sex hormones do not cause the hair-loss by themselves, it has been known that the testosterone, a kind of male sex hormones, deteriorates the 25 function of hair papillas and hair follicles and damages -1Ithe blood vessels, thereby causing hair-loss, by being converted into dihydrotestosterone (DHT) due to a reductase and then coupling with an androgen receptor. Further, there are a variety of reasons, such as lack of nutrition 5 for the hair roots and stress due to dyeing, driving, a permanent. The hair-loss has been treated in various methods, and recently, a method of radiating low-output laser to the scalp has been widely used, which is known to be able to 10 prevent hair-loss, and treat and prevent diseases of the scalp by stimulating the cells, expanding the blood vessels, activating the hair root cells, and promoting blood circulation, by using the low-output laser. On the other hand, it has known that the laser used 15 for treating the hair-loss is classified in accordance with the wavelength into semiconductor laser of 830~900nm, CO 2 laser of 10600nm, Ar laser of 488~514.6nm, Nd-Yag of laser 532nm, rub laser of 694nm, helium-neon laser of 632nm, and Erbium-Yag laser of 2940nm. 20 In particular, the low-output laser implies from the red visible light having a wavelength of 600nm or more to an infrared ray having a wavelength of 1400nm, and the magnitude of the output is 100mW ~500mW, and the amount of energy per unit area is 0.05~5.0 W/Cm2. Further, treatment 25 of other skin diseases, using infrared light, has been -2increasing. That is, light is radiated to the skin of a human body, the photon penetrates into the skin tissue, and the absorbed photo is converted into thermal energy, such that thermal energy produces a thermal effect. In 5 particular, it has been known that nitric oxides are created and activated on the inner wall of the blood vessels and self-healing power increases, such that the hair tone and quality are improved and the hairs become moist due to water supplement. Further, it has been known 10 that creation of collagen and elastin is increased by stimulating the giant cells and the fibroblasts, the oxygen in the blood stream increases and toxins are removed, such that the hair-loss is prevented and there is an effect on health of the hairs. 15 The wavelength of infrared rays used for the treatment method is a blue diode (blue light emitting diode): 400~700nm, a green diode (green light emitting diode) :470~572nm, a yellow diode (yellow light emitting diode):572~630nm, a red diode (red light emitting 20 diode):630~700nm, and a infrared diode (infrared light emitting diode):700~1,400nm etc. In particular, since the treatment method using the infrared rays is simple and has little side effects, the operation range is gradually increasing. Further, 25 recently, a method that can acquire infrared rays and low -3output laser from a semiconductor diode has been developed, such that the size of optical treatment devices is reduced and the devices can be easily used, and accordingly, they are used as products for home or portable products. 5 However, laser hair-loss treatment devices of the related art uses only the laser from a laser diode for treatment, such that not only the treatment effect is low, but the manufacturing cost is high because the assembly of the laser diode is complicated.
