Abstract

<B>APARELHO DE VENTILAçãO"<D>. A presente invenção se refere a um aparelho portátil para proporcionar ventilação a pessoas com dificuldades respiratórias. O aparelho é fornecido com uma bomba de ar comprimido, que pode ser conectada à boca ou ao nariz de um paciente, através de um dispositivo de tubo (8) para geração de pulsos de pressão, com um volume de ar individualmente adaptado. A bomba compreende um recipiente rígido consistindo de duas porções de metades simétricas (4) e com uma membrana flexível (5), que está localizada como um diafragma lateralmente recíproco entre as duas porções de metade do recipiente. Estas são fornecidas com válvulas de retenção que permitem o ar ambiente ser alimentado dentro da bomba e da bomba para dentro do dispositivo de tubo, enquanto a parede da membrana é movida para geração de pulsos de pressão. A bomba é dotada de um dispositivo flexível de tracionamento (6) para operação recíproca da membrana (5) no recipiente. O dispositivo de tracionamento se estende através de polias (1) para um dispositivo de acionamento (9) localizado substancialmente no mesmo plano do recipiente e ao lado do mesmo.
