Abstract

La invencion se relaciona con una jeringa de seguridad que comprende un cilindro, un asiento de aguja y un embolo, en donde el asiento de aguja tiene un vastago de gancho una porcion de deformacion de acoplamiento y una porcion de sujecion de cilindro; y el embolo tiene un cuerpo de vastago, y un orificio de insercion de gancho que se puede enfundar con el vastago de gancho del asiento de aguja y comprime la porcion de deformacion de acoplamiento para deformacion elastica de modo que la porcion de sujecion de cilindro del asiento de aguja no se sujete en la ranura de sujecion de asiento del cilindro, y el orificio de insercion de gancho puede enganchar el vastago de gancho del asiento de aguja para mover el asiento de aguja. La jeringa de seguridad puede permitir una colocacion estable y retraccion rapida del asiento de aguja y reducir de manera efectiva los residuos de medicina liquida.
