Abstract

Patente de Invenção: "FILTRO FLEXìVEL PARA UM RESPIRADOR". A presente invenção provê um filtro flexível (1) para um respirador possuindo partes frontal e traseira substancialmente co-extensivas de material de filtragem (3) as quais estão seladas uma à outra ao longo de sua periferia, formando uma borda selada. Uma estrutura flexível de plástico (4) está contida no interior das partes frontal e traseira (2,3) para formar uma câmara (17) entre as partes frontal e traseira (2,3) do material de filtragem (3). Um conector (10) para ligar o filtro (3) a uma máscara de respiração é formado de maneira integral com a estrutura (4) de forma que ele sobressaia através da parte traseira (3) do material de filtragem (3). Uma pluralidade de recessos é também formada de modo integral com a estrutura para facilitar o ato de agarrar o filtro (1) sem esmagá-lo ou danificá-lo.
