Desenvolvimento de uma estação de crioterapia e hipertermoterapia portátil

Abstract

Treatment via thermotherapy is widely used in physiotherapy and physical education as a means of treating various diseases through the therapeutic application of cryotherapy and hyperthermotherapy, a technique that applies heat by contact. In this project, an embedded system was developed for the portable application of thermotherapy in a thermal bag, which maintains its temperature, whether warm or cold, throughout the pre-established time. Currently, the thermal bags do not retain temperature when used for a long period of time, whether warm or cold, depending on their application, resulting in ineffective treatment. This work describes the construction and design of a portable system for performing thermotherapy, allowing adjustment of time and temperature without interruption in treatment, according to the medical literature. This project used a PIC16F874A microcontroller to perform temperature control, by Peltier effect, in a thermoelectric module, and development of a power driver to activate it. The work also proposed to carry out a study for the use of a PID controller (ProportionalIntegral-Derivative) to stabilize the compress temperature in a permanent regime.
