Abstract

<B>PROCESSO PARA LIMPEZA, DESINFECçãO E ESTERILIZAçãO DE MATERIAIS UTILIZANDO COMBINAçãO DE GáS DE FASE DENSA E RADIAçãO ULTRAVIOLETA<D> é fornecido um processo para limpar, desinfetar e esterilizar substratos compreendendo as etapas de: a) colocar o substrato contaminado em um recipiente de limpeza; b) contatar o substrato contaminado com dióxido de carbono de fase densa em forma líquida; c) submeter o substrato e dióxido de carbono de fase densa à radiação ultravioleta tendo um comprimento de onda compreendido na faixa de aproximadamente 180 a 300 nm por uma duração e intensidade suficientes para produzir uma reação fotoquímica capaz de destruir o DNA de microorganismos no substrato; d) submeter substancialmente simultaneamente pelo menos o dióxido de carbono de fase densa à agitação; e e) remover o dióxido de carbono de fase densa do recipiente de limpeza e desse modo transportar os contaminantes do substrato de tal modo que o substrato seja limpo e, no caso de roupas contaminadas, desinfetado ou, no caso de instrumentação médica e dental, esterilizado. Substancialmente simultaneamente com a exposição UV e agitação, os substratos também são submetidos a um agente de esterilização oxidante, como H~ 2~O~ 2~.
