目的：比较现有的各种剥脱性与非剥脱性嫩肤技术的优缺点，并在介绍一种新型的利用特定波段（1100nm-1800nm）的宽谱红外光嫩肤的机理的基础上，进行相应红外光嫩肤仪器的研究与设计。方法：本文首先介绍了利用该特定波段的宽谱红外光进行嫩肤的机理，然后在借鉴国内外相关产品的基础上，自主研发，使其既能在技术指标上达到国际同行产品的规格，又能极大地降低研发及生产成本。对该嫩肤仪器的总体结构采用模块化设计，包括：控制系统模块、电源模块、红外光产生模块、人机交互模块、水冷却循环模块及开关控制模块，同时详细讨论了仪器设计中需要重点考虑的如何产生治疗所要求的红外光脉冲、人机交互界面、抗干扰设计三个方面的问题。结果：本文给出了仪器的总体结构图和所实现的人机交互界面。由实验测得的该仪器产生的宽谱红外光的技术参数完全达到了设计要求并可投入临床使用。经过反复测试，该仪器在整机运行的稳定性、可靠性，以及光头出光能量的均匀性、稳定性均方面达到红外光嫩肤美容治疗的要求。结论：该产品将具有良好的医疗美容的应用前景及市场前景。

英文摘要：

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 （1100nm -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.
