Abstract in Portuguese
O objetivo da pesquisa foi o desenvolvimento de um abrangente Sistema de Circulação Extracorpórea usando o conceito integrado de segurança para equipamentos eletro-médicos. A necessidade inicial de determinação das especificações necessárias ao Sistema propiciou a definição de uma máquina coração-pulmão artificial ideal, com várias inovações e modificações. O projeto do Sistema de Circulação Extracorpórea considerando aspectos de funcionalidade, qualidade , confiabilidade e segurança, tanto do próprio aparelho como da instalação e do ambiente de paciente, conduziu ao estabelecimento de um modelo de concepção para equipamentos eletro-médicos, possibilitando inclusive a minimização dos problemas de manutenção e má utilização. A implementação e os ensaios realizados demonstraram a viabilidade do projeto e as dificuldades de desenvolvimento e construção de aparelhos para fins médicos. Estas dificuldades decorreram da inexistência de implementos e dispositivos produzidos em linhas normais de fabricação com as características exigidas pela aplicação médica. A exigência da definição precisa de diretrizes relativas à segurança de aparelhos eletro-médicos motivou uma reativação e aceleração ao processo normativo do setor.

Abstract in English
The propose of the research was the development an Extracorporeal Circulation System using the integrated concept of electromedical equipment safety. The inicial need to determine the necessary specifications for the System lead to the definition of an ideal artificial heart-lung machine. Several novel ideas and concepts were developed. Modifications od accepted industry procedures were proposed. The design of the Extracorporeal Circulation System with the contraints of safety, quality, functionality and reliability lead to the development of a general model for the design of electromedical equipment. In the design process other issues were also considered, such as ease of maintenance, minimization of hazardous consequences due to equipment misuse or the existence of harsh environments. Finally, special needs required by the installation and the patient environment were pointed out. The implementation and testing of the machine confirmed the appropriateness of the design model that was developed. It also pointed to the difficulties in the development and full scale production of medical equipment. These difficulties were related to the lack of parts and devices produced locally with the required specifications for medical applications. A by-product of all these research and development activities was the renewal of much needed work on normalization of electromedical equipment in this country.
