A syringe injection shield (100) is formed primarily from a radio-opaque substance, such as tungsten, to shield medical personnel from exposure to radiation during administration of radiopharmaceuticals to patients. Safety syringes (22) typically have a needle sheath that can be positioned around a needle (24) after administration of the radiopharmaceutical. The syringe injection shield of the present invention allows medical personnel to make the syringe "safe" before the used syringe is removed from the syringe injection shield. The syringe is safe when the needle sheath is positioned and locked in place around the needle to reduce the risk of needle stick. The syringe injection shield includes a toggle element (110) that can assume four different positions as follows: neutral; ready; hold; and release.

L'invention concerne un élément de protection pour injection par seringue (100), comprenant principalement une substance radio-opaque, telle que du tungstène, pour protéger le personnel médical de l'exposition à des rayonnements pendant l'administration de produits radiopharmaceutiques à des patients. Les seringues de sécurité (22) présentent de manière générale une gaine d'aiguille (40) pouvant être positionnée autour de l'aiguille (24), après administration d'un produit radiopharmaceutique. L'élément de protection pour injection par seringue de la présente invention permet au personnel médical de rendre la seringue <= inoffensive >= avant qu'elle ne soit enlevée de l'élément de protection pour injection par seringue. Ladite seringue est sans risque lorsque la gaine d'aiguille est positionnée et maintenue en place autour de l'aiguille, afin de réduire le risque de blessure par aiguille. L'élément de protection pour injection par seringue comprend un élément articulé (110) qui peut adopter quatre positions différentes : neutre, prêt à l'emploi, en attente, et déblocage.
