Abstract

DISPOSITIVO DE PROTEçãO RESPIRATóRIA PESSOAL. Um dispositivo de proteção respiratória pessoal (10), que compreende uma corpo de máscara (12), tem uma estrutura (35) localizada nele para receber uma fonte de suprimento de ar limpo, tal como um cartucho de filtro (14). A estrutura de recebimento de ar limpo (35) tem uma primeira parte rosqueada (34). A fonte de suprimento de ar limpo tem uma segunda parte rosqueada (58), que tem uma rosca (60) que se une com uma rosca (36) da primeira parte rosqueada (34). As primeira e segunda partes rosqueadas (34) e (58) encaixam entre si em um elevado passo de rosca e incluem um detentor integral. Um batente evita a sobre-rotação da fonte de suprimento de ar limpo (14) em relação ao corpo de máscara (12) durante a operação de fixação. O dispositivo inventivo permite que a fonte de suprimento de ar limpo (14) seja fixada ao corpo de máscara (12) com mínima rotação e é suficientemente intuitiva que os usuários podem somente precisar e uma das mãos para fixar e substituir o componente de fonte de ar limpo (14), sem ter que remover o respirador (10) de sua face.
