A shield assembly and syringe assembly comprises a syringe assembly including a syringe barrel having a needle cannula projecting distally from its distal end and a shield assembly including a guide and a shield. The guide is secured to a portion of the syringe assembly in proximity to the needle cannula. The shield includes a support wall and a pair of spaced apart side walls projecting from the support wall. At least a portion of the side walls are spaced from one another sufficiently for receiving the needle cannula therebetween. The shield is slidably engaged with the guide and is movable along a path having a generally acute angle with and toward the needle cannula from a proximal position where the needle cannula is exposed to a distal position where the needle cannula is shielded between the side walls of the shield.

Cette invention concerne une seringue à embout protecteur d'aiguille, l'ensemble étant composé d'un corps de pompe à l'extrémité distale duquel fait saillie une aiguille et d'un embout protecteur monté sur guide. Le guide est assujetti à la seringue à proximité de l'embout du corps de pompe. L'embout protecteur comprend une paroi support à laquelle sont fixées une paire de parois latérales espacées l'une de l'autre. Les parois latérales sont espacées suffisamment l'une de l'autre au moins sur une partie de leur longueur pour pouvoir recevoir entre elles l'aiguille de la seringue. L'embout protecteur coulisse dans le guide selon un angle aigu ayant pour sommet l'extrémité distale de l'aiguille, d'une position proximale où l'aiguille est exposée vers une position distale où l'aiguille est protégée..
