Abstract

La présente invention concerne un adaptateur de cylindre (220) pour une seringue (200) ayant un cylindre (218) et un piston (212). L'adaptateur comprend une pointe de cylindre (232) et un mécanisme de rétraction d'aiguille (211) ayant un sous-ensemble aiguille (221) avec une aiguille (201) et une lumière, un sous-ensemble actionneur (210), et un élément de sollicitation (240). Le sous-ensemble aiguille se déplace d'une position d'injection à une position rétractée à l'intérieur de la pointe de cylindre. Le sous-ensemble actionneur comprend un élément de retenue (224) relié à la pointe de cylindre, un stylet (254) maintenu dans un disque pour stylet (214), et une dent (242) passant dans le dispositif de retenue. Le stylet coulisse à l'intérieur de la lumière de l'aiguille et est espacé de la pointe de l'aiguille dans la position d'injection. L'élément de sollicitation sollicite le (système aiguille sur moule" (NOM) à partir de l'élément de retenue. Un agencement de verrouillage comprime l'élément de sollicitation lorsqu'il est verrouillé et libère l'élément de sollicitation lorsqu'il est actionné par la dépression du piston, ce qui déplace la dent contre l'élément de retenue. L'élément de sollicitation déplace l'aiguille et le stylet de la position d'injection à la position rétractée lorsqu'il est libéré.
