Abstract

Patente de Invenção: <B>"SISTEMAS E MéTODOS DE PROCESSAMENTO DE SANGUE EMPREGANDO BOMBAS E VáLVULAS ATUADAS POR PRESSãO"<D>. Sistemas e métodos para processamento de sangue usam pelo menos uma bomba atuada por pressão de fluido (PPN) e pelo menos uma válvula atuador de pressão de fluido (VN). Os sistemas e métodos aplicam pressões de fluido positiva e negativa para operar a bomba e a válvula. São aplicadas diferentes condições de pressão na bomba e nas válvulas (VA1 - VA25), para garantir que uma válvula usada em conjunto com uma bomba não seja superada pela pressão aplicada para operar a bomba, e que ambas a válvula e a bomba não sejam superadas pelas pressões de processamento do sistema (10) normais.
