| abstract | 1313030 Needle assembly MPL Inc 21 June 1971 [30 June 1970] 29003/71 Heading A5R A needle assembly 21 for use in bloodsampling apparatus comprises two cannulas 23, 31 mounted in a hub 25, the cannula 31 being slidable therein, and an elastic partition 27 mounted in the hub 25 and normally separating the cannulas 23, 31, the partition 27 having a slit 27a through which blunt end 31b of the cannula 31 may be slid, selectively to establish communication between the cannulas 23, 31, the slit 27a elastically returning to a closed position when the cannula 31 is removed therefrom. The cannula 23 is fixed to the hub 25, e.g. by crimping 25c. Both cannulas have pointed outer ends 23a, 31a. The cannula 31 is slidable inside a bushing (29), Fig. 3 (not shown) which has a portion (29c) forming a close frictional fit thereabout. The bushing (29) is secured inside the hub 25 by crimping the latter 25g. The bushing (29) also has a tapered end 29b serving to locate the partition 27 against a shoulder (25a), Fig. 3 (not shown) of the hub 25. The cannula 31 is flared at its blunt end 31b to limit movement away from the partition 27. The hub 25 may be secured to a conventional barrel 51, containing an evacuated glass vial 63 with a piercable rubber stopper 65, by a bayonet connection 25h, (53a') Fig. 1 (not shown) having a seal 33. The hub 25 may be of malleable metal, e.g. aluminium, the partition 27 is preferably ethylene propylene rubber, and the bushing (29) is preferably an acetal resin. |
