Patent

CA 2394362

The invention concerns a syringe comprising a syringe body (2) including an elongate barrel (4) containing a volume of medical fluid (44), one first end forming a hub (16), designed to co-operate with a needle of said syringe, a second end (6) opposite the hub and a plunger (28) mobile relative to said hub. The second end forms a closed base (6) and the plunger (28) is entirely housed inside the barrel (4). Said syringe body is inexpensive, easy to produce, provides satisfactory fluid-tightness and prevents all microbial migration towards the medical fluid.

Ce corps (2) comprend une enveloppe allongée (4) renfermant un volume de liquide médical (44), une première extrémité formant embout (16), destinée à coopérer avec une aiguille de ladite seringue, une seconde extrémité (6) opposée à l'embout et un piston (28) mobile par rapport à cet embout. La seconde extrémité forme un fond (6) fermé et le piston (28) est logé entièrement à l'intérieur de l'enveloppe (4). Ce corps de seringue est peu onéreux, de fabrication simple, assure une étanchéité satisfaisante et empêche toute migration microbienne en direction du liquide médical.
