This invention discloses an apparatus (10) for sampling fluid from a puncturable conduit, the apparatus (10) including an elongate housing (14) comprising a conduit puncturing portion (24) and a clamp (26), the conduit puncturing portion (24) being adapted to receive therein the puncturable conduit (12), a needle mount (40), mounted in the elongate housing (14), a needle (48) adapted for flow of fluid therethrough, the needle (48) being fixedly mounted in the needle mount (40) so as to have portions extending outward of the needle mount in opposite directions, a first end (52) of the needle being pointed and protruding into, but not beyond, the conduit puncturing portion (24), such that the conduit puncturing portion substantially prevents inadvertent engagement of a user's finger with the first end (52) of the needle (48), and wherein the clamp (26) is operative to clamp the puncturable conduit in the conduit puncturing portion, thereby forcing the puncturable conduit towards the first end of the needle and causing the first end to puncture the puncturable conduit. |
