Abstract

método e equipamento de avaliação da área disponível para a troca em trocadores de massa é um método e aparelho que permitem que oxigenadores de membrana, trocadores para hemodiálise e trocadores de membrana em geral, que são dispositivos de utilização médica em cirurgias complexas de alto risco como de coração com circulação extra-corpórea ou procedimentos de hemodiálise, sejam testados quanto a sua real disponibilidade de área de troca, seja para gases de respiração ou fluidos corpóreos, de uma forma simples, barata e não destrutiva, aplicável assim a todas as unidades produzidas. o controle de qualidade de uma produção fica com a utilização desta técnica individual a cada unidade' e não simplesmente por amostragem em testes destrutivos como é praticado atualmente, conferindo assim um incremento no valor do produto, pelo fato de este poder ser testado também quanto a sua área real disponível para a sua função de troca, seja de gases de respiração ou componentes removíveis pela hemodiálise, havendo um aumento na sua qualidade e confiabilidade, fornecendo à empresa que o utilizar um importante diferencial de mercado, e ao paciente, mais segurança.
