Abstract
<B>"DISPOSITIVO PARA ALIMENTAçãO DE Pó"<D>. A presente invenção divulga um método e um dispositivo para desaglomeração e carregamento eletrostático de um pó fino, preferencialmente idealizado para fins de inalação. o carregamento eletrostático se realiza por meio de um carregamento tipo tribo, corona e/ou indutivo. O dispositivo de acordo com a invenção é particularmente idealizado de ser capaz de decompor o pó diretamente dentro do ar de inspiração, para administração de, por exemplo, substâncias farmacêuticas ativas, alternativamente fornecendo um dispositivo de dosagem adicional (9) com uma quantidade de pó desaglomerada carregada eletrostaticamente, para uma dosagem ainda mais controlada da substância dentro do ar de inspiração. A desaglomeração se realiza preferencialmente através de duas escovas rotativas (2, 3) contendo pó, que são tocadas entre si. As cerdas são esfregadas entre si e, dessa forma, decompõem os aglomerados de pó. A velocidade de rotação das escovas é adequadamente otimizada para alcançar o melhor resultado possível para diferentes substâncias de pó. O modelo das escovas é ainda otimizado para as substâncias que serão desaglomeradas e eletrostaticamente carregadas, antes da etapa de administração.
