Atualização de hardwares e firmware do Protegemed

Abstract

During surgical interventions, medical teams are assisted by electromedical equipment. Its use contributes to improve operative procedures, however, exposing patients to some risks, among them, microchoke events. Protegemed allows the monitoring and real-time risk analysis of such events, contributingto patient safety. The Protegemed initial architecture has been improved since 2004, when its usingan 8-bit microcontroller, in 2017 a 32-bit ARM Cortex M3 microcontroller with nearly exhausted RAM resources is used. Due to the need for implementations of new functionalities that allow, for example,analysis of the electrical voltage in conjunction with the supply current applied to medical equipment, anew platform must be used. To determine this new version of Protegemed a research was conducted among the various development platforms currently available in the market, especially microcontrollers and single board computers. Based on the new project specifications tests were carried out on a platform of each family, where the result was the choice of ARM Cortex-M4F TM4C microcontroller. Afterthis definition, detailed implementation of the new firmware is presented along with the comparative results between previous versions and TM4C.
