"Uma abordagem para construção de modelos de dispositivos médicos para testes de sistemas médicos físico-cibernéticos".

Abstract

Cyber-Physical Systems (CPS) are systems that have emerged from the confluence of the connectivity of networks, embedded devices and computer control of physical processes. Thus, SFC are characterized as control, monitoring and supervision systems with physical and virtual components, which depend on human agents in the process. In this sense, the combination of SFC dynamic and complex physics of medical patients enable a distinct class of medical systems called Medical Cyber Physical Systems (MCPS). In the industrial area, there are plants with sensors and actuators that often rely on human agents for maintenance and control. On the other hand, in the field of health, human being is the process itself to be controlled, where sensors and actuators are medical devices and human agents are caregivers. MCPS perform monitoring and control of human health with high levels of security. This paper proposes an approach to build models of medical devices, as part of a set of artifacts to support MCPS testing. This approach is based on reference models which simulate the operation of medical devices. Technical specifications provide by manufacturers of these devices, along with guidelines provided by regulatory agencies, were used for the definition of the proposed approach. Moreover, a case study with three medical device was designed to validate the approach, creating some artifacts and reference models.
