Title
(EN) A SYRINGE
(FR) SERINGUE
Abstract
(EN)
A syringe (1) comprising a barrel (2) having an outer sheath (3) and an inner sheath (4). The outer sheath (3) has a nozzle (5) and the inner sheath also has a nozzle (6) which corresponds and fits into the nozzle (5). A needle (7) is attachable to the nozzle (6). A plunger (9) is located partly within the barrel (2) and is used to administer a drug. After the drug is administered the plunger (9) interlocks with the inner sheath (4) and as the plunger (9) is withdrawn, so is the inner sheath (4) and hence the needle (7) is retracted to be within the outer sheath (3). After the needle (7) is retracted the outer sheath (3) and inner sheath (4) are interlocked thus preventing the syringe (1) from being used again as well as locking the needle (7) in a retracted position within the outer sheath (3).
(FR)
La seringue décrite (1) comprend un canon (2) présentant une enveloppe externe (3) et une enveloppe interne (4). L'enveloppe externe (3) est pourvue d'un bec (5) et l'enveloppe interne est également pourvue d'un bec (6), qui correspond et s'adapte au bec (5). Une aiguille (7) peut être fixée au bec (6). Un plongeur (9) est disposé partiellement dans le canon (5) et est utilisé pour administrer un médicament. Après l'administration du médicament, le plongeur (9) se bloque par rapport à l'enveloppe interne (4) et, lors du retrait du plongeur (9), l'enveloppe interne (4) sort également et l'aiguille (7) se rétracte par conséquent dans l'enveloppe externe (3). Après la rétraction de l'aiguille (7), l'enveloppe externe (3) et l'enveloppe interne (4) se bloquent mutuellement empêchant ainsi toute nouvelle utilisation de la seringue (1) et bloquant également l'aiguille (7) en position rétractée dans l'enveloppe externe (3).
