Simple Low Level Laser Therapy device approach

Low Level Laser Therapy is an application of light over the injuries or lesions to improve the healing. When the correct intensity and treatment times are used, laser light can reduce oxidative stress and increases the Adenosine Tri-Phosphate which improves cell´s metabolism and increases its health. The aim of this work is to develop a genuine low level laser therapy device consisting of a main unit and four probes which allow the user to select the modulation frequency, the exposure time and the laser power density delivered to the irradiated surface. It were designed a seven convergent beams probe which provides a wavelength of 655 nm, a single beam probe with a wavelength of 808 nm and another two probes consisting of 19 and 13 laser diodes at a wavelength of 635 nm. The hardware has a simplified approach while the device has a comprehensive genuine embedded firmware achieved in Flowcode^®-4, a visual programming tool for microcontrollers.
