Abstract

CONJUNTO DE CÂNULA, PARTICULARMENTE PARA A EXTRAÇÃO DE LÍQUIDO DE UM CORPO. A invenção se refere a um conjunto de cânula (1) que compreende um porta-cânulas (6) e uma cânula (10) mantida no mesmo. Uma seção final de canal de fluxo (32) distal de um canal de fluxo (9) do porta-cânulas (6) apresenta, vista em corte axial, uma forma de seção transversal escalonada com várias dimensões transversais (35, 36, 37) diferentes entre si e diminuem em sentido axial. Cada dimensão transversal (35, 36, 37) define uma seção de admissão própria (38, 39, 40) para a respectiva cânula (10) a ser admitida na mesma. Cada uma das dimensões transversais (35, 36, 37) das seções de admissão (38, 39, 40) é formada de modo a poder admitir, respectivamente, aquela cânula (10) com uma dimensão transversal de cânula correspondente (34).
