Abstract

La présente invention concerne une base d'aiguille intérieure à aiguille remplaçable destinée à être utilisée dans une seringue à autodestruction sûre, comprenant un corps de base d'aiguille. Le corps de base d'aiguille est disposé en son sein dans un composant (7) de verrouillage-rétraction de type manchon intérieur. La partie supérieure du corps de base d'aiguille forme une partie de montage d'aiguille remplaçable (1). La partie inférieure du corps de base d'aiguille forme une partie de butée (2) d'étanchéité souple. La partie de montage d'aiguille remplaçable (1) et la partie de butée (2) d'étanchéité souple sont soit une structure intégrée à corps unique soit une structure assemblée de corps séparés. Une fente d'amortissement annulaire (3) est disposée sur la surface de la partie de butée (2) d'étanchéité souple. La paroi extérieure de la partie de butée (2) d'étanchéité souple à l'extérieur de la fente d'amortissement annulaire (3) forme une partie de mise en prise d'étanchéité souple pouvant former une entrée en prise amortie avec la paroi intérieure d'un corps de cylindre. Une partie de verrouillage-mis en prise (14) correspondant à une pièce de rétraction de piston est disposé dans une cavité du composant de verrouillage-rétraction (7) de type manchon intérieur. Lorsque la partie de verrouillage-rétraction (14) et la pièce de rétraction de piston sont mises en correspondance l'une avec l'autre, les deux rétractent le piston, ce qui permet de rétracter dans le corps de cylindre la base d'aiguille et de le faire dévier vers un côté, tandis qu'une aiguille d'injection oscille ainsi vers un côté de la paroi intérieure du corps de cylindre et est verrouillée par une partie de col du corps de cylindre, ce qui évite à l'aiguille d'injection et la base d'aiguille d'être de nouveau poussées hors de la partie de col du corps de cylindre, empêchant ainsi de manière efficace une lésion secondaire due à l'aiguille qui est de nouveau poussée vers l'extérieur.
