Sistemas de acionamento para bombas de infusão de múltiplos canais.

Abstract

According to the Food and Drug Administration - FDA, infusion pumps are currently considered the most safety-critical medical device due to the nature of their operations and associated risks. Design of these devices is still an open question and several improvement initiatives are under research. However, the released specifications of such systems are not yet adapted to the current state-of-art systems architectural developments. For example, in this work, we could not identify any project meeting the patterns of views and viewpoints for specification and documentation of system and software architectures during the engineering process. Due to this, this dissertation proposes a functional specification of an architecture for infusion pumps that can be realized through several technological trends for these products in order to improve safety. The presented architectural specification was validated by the development of a multichannel prototype of an infusion pump that can be programmed through data retrieved from a web service using a mobile application as a remote control and changing the infusion parameters according to medical prescription. Thus, the main contribution of this paper can be presented as a distributed architecture for this sort of device, allowing early integration with Electronic Health Records for the embedded systems domain implying in risk reductions during the programming activity.
