Patent

CA 2592576

The invention is a shield (11) for a syringe (10) with a needle (18) where the shield (11) is moveable between a retracted position where the syringe (10) and needle (18) can be used and a shielding position where at least the tip of the needle (18) is covered to prevent accidental needle stick injuries, comprising a shield (11) slidably attached to the body of the syringe (10) that can be moved between retracted and shielding positions to at least shield the tip of the syringe needle (18) and locking means (12) comprising at least one forward facing resilient prong (15) located with respect to the syringe (10) and a projection (16) on the shield (11) whereby the projection (16) can deflect the prong (15) to pass over it, but abuts against the moveable end of the prong (15) to thereby prevent rearward movement of the shield (11).

L~invention concerne un élément de protection (11) pour une seringue (10) dotée d~une aiguille (18), l~élément de protection (11) étant mobile entre une position rentrée dans laquelle la seringue (10) et l~aiguille (18) peuvent être utilisées et une position de protection dans laquelle la pointe au moins de l~aiguille (18) est couverte afin d~éviter toute blessure accidentelle par piqûre de l~aiguille. L~élément de protection (11) est attaché de façon à pouvoir coulisser sur le corps de la seringue (10) et est mobile entre une position rentrée et des positions de protection dans lesquelles il protège au moins la pointe de l~aiguille (18) de la seringue. Il comporte un moyen de verrouillage (12) comprenant au moins une branche élastique tournée vers l~avant (15) placée par rapport à la seringue (10) et une protubérance (16), de façon à ce que la protubérance (16) fasse fléchir la branche (15) et passe par-dessus, en venant toutefois buter sur l~extrémité mobile de la branche (15) pour empêcher ainsi le recul de l~élément de protection (11).
