Abstract

Cette invention concerne un boîtier pour aiguille (1) comportant une paroi supérieure (3), une paroi inférieure (2), une jupe annulaire (4) et une base annulaire (5). Sous ladite base (5) est disposée une couche de matière (6) imprégnée d'adhésif ou éventuellement une surface à friction antidérapante et rugueuse. Un élément (7) fait saillie vers l'intérieur du boîtier, sous la jupe (4). Cet élément en saillie (7) est conçu pour entrer légèrement en contact avec la surface (16) périphérique externe du manchon (12) de l'aiguille avant l'utilisation. De manière à enfermer hermétiquement le manchon (12) de l'aiguille et l'aiguille (10) à l'intérieur du boîtier (1), un élément d'étanchéité du type patte d'arrachage (17) est collé à la surface supérieure de la jupe (14). Le boîtier (1) peut être tenu par l'utilisateur, attaché à une surface horizontale fixe ou supporté par une telle surface avant le retrait de l'aiguille (10) et de son manchon (12) en vue d'une utilisation. Lorsqu'on arrache la patte d'arrachage (17) de la jupe (4), le manchon (12) est découvert et peut être fixé à une seringue de façon à être extrait du boîtier (1). Après l'utilisation, le manchon (12) et l'aiguille (10) sont réintroduits fermement, de façon permanente, à l'intérieur du boîtier (1) pour être conservés en toute sécurité sous la partie en saillie (7) au-delà de laquelle le manchon (12) est encliqueté à l'intérieur du boîtier (1).
