Abstract

Se proporcionan un émbolo, un ensamble de aguja, y una jeringa retráctil que los contiene. El émbolo comprende un miembro de émbolo y un émbolo exterior que tiene un resorte de bloqueo que evita o impide el movimiento del miembro de émbolo después de la retracción de la aguja. El émbolo además comprende otro elemento de bloqueo para acoplar el cilindro para evitar o impedir el movimiento adicional del émbolo exterior después del suministro de contenido líquido. El miembro de émbolo tiene un sello de émbolo que se acopla con una aguja retráctil del ensamble de aguja para la retracción. La aguja retráctil comprende una cánula y un cuerpo de aguja con una pluralidad de canales de fluido que cooperan con un conducto de fluido del sello de émbolo para dirigir de manera eficiente el fluido a la cánula. Un retenedor de aguja comprende una pluralidad de brazos con salientes acoplado de manera liberable al cuerpo de aguja, por lo que un eyector con pestañas facilita la liberación de la aguja retráctil del retenedor de aguja para permitir la retracción impulsada por resorte comprimido.
