Abstract

a presente invenção refere-se a um adaptador de cilindro (220) para uma seringa (200) tendo um cilindro (218) e êmbolo (212). o adaptador compreende uma ponta de cilindro (232) e um mecanismo de retração da agulha (211) tendo um subconjunto de agulha (221) com uma agulha (201) e um lúmen, subconjunto de atuador (210) e membro de inclinação (240). o subconjunto de agulha move-se de uma posição de injeção para uma de retração dentro da ponta de cilindro. o subconjunto de atuador inclui um retentor (224) conectado na ponta de cilindro, um estilete (254) retido em um disco de estilete (214) e um dente (242) passando para dentro do retentor. o estilete desliza dentro do lúmen da agulha e está espaçado da ponta de agulha na posição de injeção. o membro de inclinação inclina a nom relativamente ao retentor. um instrumento de fixação comprime o membro de inclinação quando trancado e libera o membro de inclinação quando atuado por pressão do êmbolo, que move o dente contra o retentor. o membro de inclinação move a agulha e estilete da posição de injeção para a posição retraída quando liberado.The present invention relates to a barrel adapter (220) for a syringe (200) having a barrel (218) and plunger (212). the adapter comprises a cylinder tip (232) and a needle retracting mechanism (211) having a needle subset (221) with a needle (201) and a lumen, actuator subset (210) and tilt member (240) ). the needle subset moves from an injection position to a retraction position within the cylinder tip. the actuator subset includes a retainer (224) attached to the cylinder end, a stylus (254) retained on a stylet disc (214), and a tooth (242) passing into the retainer. the stylus slides into the needle lumen and is spaced from the needle tip in the injection position. the tilt member inclines the notch relative to the retainer. A clamping instrument compresses the tilt member when locked and releases the tilt member when actuated by piston pressure, which moves the tooth against the retainer. the tilt member moves the needle and stylus from the injection position to the retracted position when released.
