Abstract

APARELHO DE ESTERILIZAÇÃO PARA A PRODUÇÃO DE PLASMA E RADICAIS HIDROXILA. A invenção se refere a sistemas de esterilização adequados para uso clínico, por exemplo, no corpo humano, aparelhos médicos ou espaços de leito hospitalar. A invenção fornece um aparelho de esterilização compreendendo: uma fonte de micro-ondas disposta para gerar energia de micro-ondas; um gerador de névoa disposto para gerar um fluxo de névoa de água; um suprimento de gás; um distribuidor conectado para receber o fluxo de névoa de água do gerador de névoa; e uma pluralidade de aplicadores de plasma conectados ao distribuidor, em que cada aplicador de plasma é conectado para receber energia de micro-ondas da fonte de micro-ondas e um fluxo de gás do suprimento de gás, em que cada aplicador de plasma é configurado para atingir um plasma em uma extremidade distal do mesmo, em que as extremidades distais da pluralidade de aplicadores de plasma são dispostas em uma região geradora de plasma definida pelo coletor, e em que o coletor é configurado para direcionar o fluxo de névoa de água através da região geradora de plasma para uma saída do mesmo.
