A retractable and extendable medical needle protective shield (50, 50') which provides for accessing and reaccessing a medical needle (40) and associated sharpened needle tip (100) and recovering the needle (40) and tip (100) for safety between accesses. The shield (50, 50') includes a needle guide (130, 138) which assures the needle tip (100) is untouched by any part of the shield (50, 50') as the shield (50, 50') is displaced to cover and uncover the needle (40). A releasible latch (148, 162) is provided to guard against inadvertent removal of the protective shield (50, 50') between accesses. An unreleasible latch (182, 190) is also provided to secure the shield (50, 50') relative to the latch (182, 190) preparatory to final disposal.

La présente invention concerne un cache protecteur pour aiguille médicale (50, 50'), rétractable et extensible, qui permet d'accéder et de réaccéder à une aiguille médicale (40) et à la pointe d'aiguille effilée qui lui est associée (100) et de recouvrir l'aiguille (40) et la pointe (100), afin d'assurer la sécurité entre les accès. Le cache (50, 50') comprend un guide d'aiguille (130, 138) qui permet à la pointe d'aiguille (100) de ne pas être touchée par une quelconque partie du cache (50, 50') lorsque ce cache (50, 50') est déplacé afin de couvrir et de découvrir l'aiguille (40). Un dispositif de fermeture détachable (148, 162) assure la protection contre un retrait accidentel du cache protecteur (50, 50') entre les accès. Un dispositif de fermeture non détachable (182, 190) permet de bloquer le cache (50, 50') par rapport au dispositif de fermeture (182, 190) avant l'élimination finale.
