Patent

CA 2205936

This invention pertains to an intravenous infusion set and in particular, a winged needle assembly used for venipuncture having an integral hollow tubular protective member to reduce accidental needle sticks from such infusion set. The tubular member has a slot engagable by the wing on the rotatable hub and needle. Once aligned, the winged hub is pulled back into the slot and disengages at a lock-out position. The lateral notch retains the hub and needle within the tubular member.

L'invention concerne un ensemble de perfusion intraveineuse, et notamment un ensemble aiguille à ailette utilisé pour la veinopuncture, présentant un élément protecteur solidaire tubulaire creux, afin de réduire les piqûres accidentelles d'aiguille par cet ensemble de perfusion. L'élément tubulaire présente une fente dans laquelle s'engagent l'ailette située sur le moyeu rotatif et l'aiguille. Une fois aligné, le moyeu à ailette est tiré jusque dans la fente et se détache au niveau d'une position de blocage. L'encoche latérale retient le moyeu et l'aiguille à l'intérieur de l'élément tubulaire.
