Abstract

La invención se relaciona con una jeringa de seguridad que comprende un cilindro, un asiento de aguja y un émbolo, en donde el asiento de aguja tiene un vástago de gancho una porción de deformación de acoplamiento y una porción de sujeción de cilindro; y el émbolo tiene un cuerpo de vástago, y un orificio de inserción de gancho que se puede enfundar con el vástago de gancho del asiento de aguja y comprime la porción de deformación de acoplamiento para deformación elástica de modo que la porción de sujeción de cilindro del asiento de aguja no se sujete en la ranura de sujeción de asiento del cilindro, y el orificio de inserción de gancho puede enganchar el vástago de gancho del asiento de aguja para mover el asiento de aguja. La jeringa de seguridad puede permitir una colocación estable y retracción rápida del asiento de aguja y reducir de manera efectiva los residuos de medicina líquida.
