A needle assembly including a cover (100) , an inner shield (200) , a needle (300) and a hub assembly (400) is provided. After use, the cover is placed over the distal (patient) end of the needle and the inner shield can be used to cover the proximal (non-patient) end of the needle . The inner shield comprises flexible extensions (220) above its open end to secure the inner shield over the proximal end of a needle in the needle assembly. A needle hub is also provided that eliminates adhesive bumps at the base of the needle and further distributes needle angular bending along an irregular surface, which facilitates proper insertion technique and effective needle length. The hub further includes stanchions or castellations on its edge such that when the patient uses proper injection techniques, the edges of the hub leave a distinctive impression in the skin of a user for a short period of time.
Ensemble aiguille comprenant une coiffe (100), une protection intérieure (200), une aiguille (300) et un ensemble embout (400). Après usage, la coiffe est placée par-dessus l~extrémité distale (côté patient) de l~aiguille et la protection intérieure peut être utilisée pour couvrir l~extrémité proximale (côté opposé au patient) de l~aiguille. La protection intérieure comprend, au-dessus de son extrémité ouverte, des protubérances souples (220) servant à la fixer par-dessus l~extrémité proximale de l~aiguille dans l~ensemble aiguille. Un embout d~aiguille permet de supprimer les bosses d~adhésif à la base de l~aiguille et de répartir la flexion angulaire de l~aiguille le long d~une surface irrégulière, pour faciliter l~insertion correcte de l~aiguille et en optimiser la longueur efficace. Les bords de l~embout comportent en outre des colonnettes ou crénelages de façon à laisser une empreinte temporaire distinctive dans la peau d~un patient lorsque celui insère l~aiguille correctement.
