An intradermal needle (100) comprising a needle cannula assembly (10) having a limiter portion (12), a hub portion (14) and a needle cannula (36), a protective cap having a forward (16) and rearward (17) cap to protect and shield a needle cannula prior to and after use, and means for engaging (52+50) the needle cannula assembly,and the rearward cap after use. The mated forward and rearward cap provide a sterile enclosure for the needle cannula assembly prior to use. Removing the rearward cap permits the needle cannula assembly to be coupled to a drug delivery device, while the forward cap removably shields the needle cannula. Removing the forward cap then exposes the needle cannula for use. After use, the distal end of the needle cannula assembly is placed into the rearward cap and lockingly engaged therewith.

L'invention concerne une aiguille intradermique (100) comprenant une canule (10) présentant une partie de délimitation (12), un raccord (14) et une canule (36), un capuchon protecteur présentant un capuchon avant (16) et arrière (17) permettant de protéger et de recouvrir une canule avant et après utilisation, ainsi que des moyens d'insertion (52 + 50) de l'ensemble canule et le capuchon arrière après utilisation. Les capuchons avant et arrière assurent une fermeture stérile pour l'ensemble canule avant l'utilisation. Le retrait du capuchon arrière permet à l'ensemble canule d'être couplé à un dispositif d'administration de médicament, alors que le capuchon avant recouvre momentanément la canule. Le retrait du capuchon avant expose la canule en vue de son utilisation. Après l'utilisation, l'extrémité distale de l'ensemble canule est placée dans le capuchon arrière et y reste insérée.
