<p>A cannula support assembly comprises a hub subassembly, which supports the cannula, and a cover subassembly, which attaches to the hub subassembly to sealingly enclose the cannula prior to use and which can be easily removed from and subsequently reattached to the hub subassembly, if desired. Each subassembly is itself preferably fabricated from one or more individually extruded component parts which can be assembled together in a manner lending itself to cost efficient, automated production techniques and which thereby obviates the use of substantially more costly injection molded or compression molded plastic parts. The resulting support assembly is durable, easily attachable to flexible tubing, and readily adaptable to diverse uses, such as a hub and cover for a phlebotomy needle or an inline sampling needle.</p> |
