Patent

CA 2167270

The several embodiments include a hypodermic needle (1) with a hollow member (5A) positioned over a portion of the needle, thus covering that portion of the needle. Prior to and during use, the hollow member is held away from the piercing end of the needle to allow it to be used m the normal manner. After the needle has become contaminated, a simple action by the user places the hollow member in a position covering the piercing end of die needle and the hollow member is supported in this position against rearward pressure. The hollow member is similarly kept from sliding off the end of the needle.

Plusieurs modes de réalisation ont une aiguille hypodermique (1) comportant un élément creux (5A) positionné sur une partie de l'aiguille et recouvrant par conséquent cette partie. Avant et pendant l'utilisation, l'élément creux est maintenu éloigné de la pointe de l'aiguille afin de pouvoir utiliser celle-ci normalement. Après que l'aiguille ait été contaminée, il suffit à l'utilisateur d'une simple action pour placer l'élément creux dans une position qui recouvre la pointe de l'aiguille, et l'élément creux est soutenu dans cette position contre la pression arrière. L'élément creux de la même façon ne peut glisser de l'extrémité de l'aiguille.
