Abstract
Patente de Invenção para <B>"PROCESSO E DISPOSITIVO PARA SUPRIR AR MODIFICADO"<D> A presente invenção se refere a um dispositivo onde o ar deficiente em oxigênio é suprido pelo saco complacente (1) munido de um interruptor (1d), que comanda a abertura da válvula (2g) quando o volume do saco complacente (1) atinge seu limite inferior (V~ min), de maneira a ligar o ejetor (2) na fonte de nitrogênio (4), de injetar o nitrogênio e aspirar o ar ambiente para dentro do ejetor (2) e de encher o saco complacente (1) de ar deficiente em oxigênio, à pressão ambiente, e levantá-lo pela máscara respiratória (3). A válvula (2f) comanda a aspiração de ar ambiente no ejetor (2) e ajusta o teor em oxigênio do ar dentro do saco complacente (1). O enchimento do saco complacente (1) é repetido até 10 vezes por minuto, em função da quantidade de ar levantado, cada vez que o volume do saco complacente atinge seu limite inferior (V~ mim). O saco complacente (1), com um volume útil de 20 litros, libera de 5 1/min a 200 1/min de ar deficiente em oxigênio. A invenção é particularmente útil nos treinos esportivos, permitindo simular a respiração de ar em alta altitude.
