Study and Design of Broad -spectrum (1100nm～1800nm) Infrared Light -Based Skin Rejuvenation System / 中国医学物理学杂志

ABSTRACT

Objective: Compare merits and drawbacks of existing ablative and non-ablative rejuvenation technologies, and complete study and design of a skin rejuvenation device based on a new rejuvenation mechanism using broad-spectrum infrared light (1100 nm ～1800nm). Methods: This article firstly presents skin rejuvenation mechanism based on the broad-spectrum infrared light, and then independently design by using corresponding systems at home and abroad for reference to make a high-quality device with lower costs compared to international corresponding systems. The device has a modular architecture design including system control module, power module, infrared emission, human machine interface, water circulating cooling and switch control module. The article details three key points in design: how to generate the required infrared pulsed light, human machine interface and anti-interference design. Results: The article gave the architecture diagram and human machine interface. The technical parameters measured by experiments satisfied the design requirements and the device can be used in clinics. Its stability, reliability and energy uniformity all meet requirements of infrared rejuvenation treatment. Conclusion: The device will have good applying prospect and market prospect in medical cosmetics.
