Abstract

1 / 1 resumo “respirador com camada de modelagem de espuma com passagens de ar circundadas por regiões rebaixadas” é apresentada uma máscara facial filtrante 10 que tem um arnês 14 e um corpo da máscara 12. o corpo da máscara 12 inclui uma estrutura de filtração 18 e a camada de modelagem em formato de bojo 20, sendo que esta última compreende uma camada de espuma de célula fechada que tem uma pluralidade de aberturas permeáveis a fluidos 22 localizadas na mesma. as aberturas 22 são circundadas por regiões rebaixadas 31. a estrutura de filtração 18 não faz contato substancial com a camada de modelagem 20 nas regiões rebaixadas. a camada de modelagem 20 faz contato com a face do usuário no perímetro do corpo da máscara 19 quando o respirador está sendo usado. o uso de uma camada de modelagem de espuma que tem aberturas circundadas por regiões rebaixadas fornece integridade estrutural ou rigidez suficiente para evitar que o corpo da máscara ceda durante o uso do respirador, embora também exiba uma baixa queda de pressão e rápida distribuição fluida de ar no interior da máscara para permitir baixa resistência à respiração e para conforto do usuário.
