Abstract
<B>APARELHO DE AMOSTRAGEM DE FLUIDO<D>. A presente invenção revela um aparelho (10) para amostar fluido de um conduto perfurável, o aparelho (10) incluindo um alojamento alongado (14) compreendendo uma porção de perfurar conduto (24) e um prendedor (26), a porção de perfurar conduto (24) sendo adaptada para receber na mesma o conduto perfurável (12), um suporte de agulha (40), montado no alojamento alongado (14), uma agulha (48) adaptada para fluxo de fluido através da mesma, a agulha (48) sendo fixamente montada no suporte de agulha (40) de modo a ter porções se estendendo para fora do suporte de agulha em direções opostas, uma primeira extremidade (52) da agulha sendo pontuada e se projetando para dentro, porém não além, da porção de perfurar conduto (24), de tal modo que a porção de perfurar conduto evita susbtancialmente engate inadvertido de dedo de um usuário com a primeira extremidade (52) da agulha (48), e em que o prendedor (26) é operante para prender o conduto perfurável na porção de perfuração conduto, desse modo forçando o conduto perfurável em direção à primeira extremidade da agulha e fazendo com que a primeira extremidade perfure o conduto perfurável.
