CA 2508360

A medical needle shield apparatus is provided that includes a first cylinder, such as, for example, a shield (102) that is extensible from a retracted position to an extended position for enclosing a distal end of a needle (104) of a medical needle device. The shield includes a collar (108) that is mounted to the medical needle device. The shield further includes a proximal portion (110) extending from the collar and a distal portion (112) extending from the proximal portion. The distal portion is configured to enclose the distal end of the needle in the extended position. The proximal portion includes an engagement surface (114) that is engageable to urge the shield from the retracted position to the extended position. The collar includes a guard (116) extending therefrom and is disposed adjacent to the distal portion of the shield in the retracted position such that inadvertent extension of the shield, via engagement of the distal portion, is prevented.

L'invention concerne un système servant à protéger des aiguilles médicales et comprenant un premier cylindre, tel qu'une gaine extensible depuis une position de rétraction jusqu'à une position d'extension recouvrant l'extrémité distale de l'aiguille d'un dispositif médical comportant une aiguille. Cette gaine possède un collier monté sur ledit dispositif. Elle comporte également une partie proximale s'étendant depuis le collier et une partie distale s'étendant depuis la partie proximale. Cette partie distale est conçue pour entourer étroitement l'extrémité distale de l'aiguille en position d'extension. La partie proximale comporte une surface de contact permettant de pousser la gaine de sa position de rétraction à sa position d'extension. Une garde s'étend depuis le collier et est située en position contiguë à la partie distale de la gaine en position de rétraction, de manière à empêcher toute extension involontaire de la gaine par l'intermédiaire du contact de la partie distale.
