Abstract

APARELHO PARA FLUXO CONTROLADO DE MATERIAIS FLUIDOS PARA USO EM MATERIAIS MÉDICOS. A presente invenção refere-se a um aparelho para fluxo controlado de materiais fluidos para uso em acessórios médicos que possui um primeiro alojamento com um corpo, uma primeira extremidade aberta, uma segunda extremidade aberta e um interior oco. A segunda extremidade se ajusta a um primeiro acessório médico para fazer fluir os materiais fluidos através do interior oco de um primeiro acessório médico. O aparelho também possui um segundo alojamento com uma extremidade aberta, uma primeira extremidade aberta, um interior oco e uma segunda extremidade aberta e que possui um furo axial em posição coaxial em relação ao interior oco do primeiro alojamento. A segunda extremidade do segundo alojamento se ajusta à primeira extremidade aberta do primeiro alojamento. A primeira extremidade aberta do segundo alojamento se ajusta ao segundo acessório médico, através do que o segundo acessório médico recebe materiais fluidos a partir do primeiro acessório médico através do interior oco do corpo.
