Patent

CA 2256678

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.

L'invention concerne un appareil (10) pour échantillonner un fluide provenant d'un conduit perforable, cet appareil (10) comportant un boîtier allongé (14) comprenant une partie (24) perforant le conduit, et un système de serrage (26), la partie (24) perforant le conduit étant adaptée pour recevoir le conduit perforable (12), un support d'aiguille (40) monté dans le boîtier allongé (14), une aiguille (48) adaptée pour permettre l'écoulement de fluide, cette aiguille (48) étant montée à demeure dans le support d'aiguille (40) de manière à avoir des portions s'étendant vers l'extérieur du support dans des sens opposés, une première extrémité (52) de l'aiguille étant pointue et faisant saillie dans, mais pas au-delà, la partie (24) perforant le conduit, de sorte que cette dernière empêche sensiblement le contact par inadvertance de la main de l'utilisateur avec la première extrémité (52) de l'aiguille (48), le système de serrage (26) servant à serrer le conduit perforable dans la partie le perforant, poussant ainsi le conduit perforable vers la première extrémité de l'aiguille qui le perfore.
