980nm Laser Vascular Removal Machine , Laser Treatment For Thread Veins

Product Specification

Brief Introduction

SDL-G Diode 980nm Laser Therapy system is precise medical laser equipment, which is developed for medical applications. The systems of this Device have gone through strict safety test and standard operation will not bring about malfunctions. Therefore, for the safety of operating personnel and patients from being injured by laser radiation, please carefully read this chapter and relevant connects in other chapters. Besides, operating personnel of laser Device should have taken medical laser technology training and are qualified. SDL-G Diode 980nm Laser Therapy system belongs to Class 4 laser products, which has high energy, thus people should be very careful during process of operating the Device. Any inflammable goods should not be closed to laser beams.

Eyes Protection

Warning

Direct or indirect observing of laser beams, reflected beams and scattering beams is forbidden. Direct observing of laser beams from optical output or hand piece is absolutely prohibited, because it will cause damage to retina. NOHD-Nominal Ocular Hazard Distance NOHD represents that irradiance or exposure dose are lower than the Maximum Permissible Exposure (MPE) distances. The NOHD value of this Diode Laser Device is 4.57meters, if it is not intended observation. Safety goggles in the workshop should be marked with obvious signs so as to guarantee all persons including patients wear safety goggles and protect eyes’ from being injured. Safety goggles with relevant wavelength are randomly equipped with Device.

Technological Theory

The target substance of vascular disease treatment is oxyhemoglobin in red blood cell in blood vessel. Wavelength affects laser’s depth of penetration. Under 1200nm, the longer the wavelength, the deeper laser can penetrate. Thus, laser wavelength is usually longer in vascular disease treatment so as to give consideration to target tissues’ selective absorption and penetrability. Besides, laser penetrates the epidermis melanin barrier and reaches targeted blood vessels. Short wavelength laser light will be competitively absorbed by epidermis melanin, which will cause epidermis injury and form cicatrix. 980nm Diode 980nm Laser Therapy system takes advantage of 980nm wavelength laser, penetrating epidermis and reaching blood vessels. Based on selective photothermolysis theory, oxyhemoglobin absorbs laser energy and produces thermal energy and spreads to vascular endothelial cells through conduction mechanism. In consequence, blood vessel wall is damaged and facial vascular will be treated.

The major targeted chromophore in facial vascular treatment is oxyhemoglobin that existing in red blood cell in vessels. According to the curve of laser absorption by targeted substance (right picture), oxyhemoglobin shows a much higher absorption interval in 900nm-1000nm. Thus 980nm semi-conductor laser has the ideal treatment effects for facial vascular removal.
