Abstract

"CAPUZ RESPIRADOR A SER VESTIDO SOBRE A CABEçA DE UM USUáRIO PARA PROVER UM SUPRIMENTO DE AR RESPIRáVEL A UMA REGIãO DA FACE DO USUáRIO". A invenção refere-se a um capuz respirador (1) que tem uma câmara de ar (6) disposta acima da cabeça de um usuário para suprimento de ar respirável. A câmara de ar (6) tem uma entrada de ar (13) conectada com uma mangueira de suprimento de ar (5) e uma saída de ar (17). A saída (17) é disposta para dirigir ar para longe dos olhos do usuário. A câmara de ar (6) forma um duto de ar (12) que substancialmente cobre o topo do capuz (1) acima da cabeça do usuário. O duto (12) é resistente a retração, de modo que a forma do duto é mantida no uso e fluxo de ar através do duto (12) é substancialmente irrestrito. Como um resultado, um fluxo de ar substancialmente uniforme pode ser atingido, no uso, padrão de fluxo de ar este que pode ser repetido de um dia para outro e de um capuz para outro.
