Abstract
APARELHO DE ESTERILIZAÇÃO PARA A PRODUÇÃO DE PLASMA E RADICAIS HIDROXILA. A invenção refere-se a sistemas de esterilização adequados para uso clínico, por exemplo, no corpo humano, aparelhos médicos ou espaços de leito hospitalar. Em particular, um dispositivo de esterilização é fornecido para gerar um fluxo de radicais hidroxila, o dispositivo de esterilização compreendendo: uma linha de transmissão coaxial, a linha de transmissão coaxial se estendendo em uma direção longitudinal e compreendendo um condutor interno e um condutor externo localizado em torno e afastado do condutor interno; uma tampa de extremidade montada em uma extremidade distal da linha de transmissão coaxial, em que a tampa de extremidade compreende uma abertura de saída voltada distalmente; um conduíte de fluido que se estende na direção longitudinal a partir de uma entrada de fluido em uma extremidade distal da linha de transmissão coaxial através da tampa de extremidade para a abertura de saída; e uma região de geração de plasma em uma extremidade proximal da abertura de saída, em que a região de geração de plasma contém um primeiro eletrodo que está eletricamente conectado ao condutor interno e um segundo eletrodo que está eletricamente conectado ao condutor externo, em que o conduíte de fluido define um caminho de fluxo de fluido longitudinal através do dispositivo que está alinhado com uma direção de alimentação na qual o fluido é recebido através do fluido e em que o primeiro eletrodo e o segundo eletrodo se opõem um ao outro em uma direção transversal através do caminho de fluxo de fluido longitudinal na região geradora de plasma.
