Abstract

In recent years, the application of multi-wavelength low-level laser therapy for some acute and chronic diseases and improving the quality of treatment has brought a lot of positive achievements in medicine. It is increasingly popular in both experimental and clinical trials. It is highly demanded to design and develop phototherapy laser devices for specific applications. In this study, a multi-wavelength phototherapeutic device that emits in the red to near-infrared region, the phototherapeutic window region, is developed. The device uses laser modules, allowing easily focus laser beams on the targeted therapy zone. For the convenience of the user, the device integrates a digital control system, a touch screen that easily selects optimal parameters such as power, wavelength, and operating mode for specific therapeutic purposes. This paper presents the design and complete implementation of the device and the laser module fabrication technique as well. The main parameters of the laser therapy device are given, which meet the specifications of a phototherapeutic device and suit open and chronic wound healing based on the photobiomodulation effect.
