Beschreibung
Zusammenfassung:	A spring loaded automatic retractable needle syringe is disclosed wherein a compressed spring (50) is placed between a needle carrier (40) and the distal end of the barrel and a cap (13) placed over the distal end of the barrel. A releasable retaining means (60) is provided to hold the needle carrier at the distal end. The needle (30) extends through an opening in the end of the cap which is covered by a puncture pad (15). When the releasable retaining means (60) is released the compressed spring (50) pushes the needle carrier (40) back up completely into the barrel (10). The puncture pad (15) seals the opening in the cap. Seringue à aiguille à escamotage automatique, montée sur ressort. Un ressort comprimé (50) est disposé entre un support d'aiguille (40) et l'extrémité distale du cylindre, un bouchon (13) couvrant l'extrémité distale du cylindre. Un organe libérable (60) de retenue permet de maintenir le support d'aiguille sur l'extrémité distale. L'aiguille (30) traverse une ouverture, pratiquée dans l'extrémité du bouchon, et couverte par un joint de perforation (15). Lorsque l'organe libérable (60) de retenue est libéré, le ressort comprimé (50) repousse le support d'aiguille (40) complètement à l'intérieur du cylindre (10). Le joint de perforation (15) ferme l'ouverture du bouchon.
