Abstract

El sistema protector de la invención, destinado a evitar la reutilización de las jeringas, de accionamiento automático, incluye, un elemento (8) extensible a modo de fuelle, en virtud de su recuperación de resorte, encerrando en su interior a la aguja (8) hipodérmica de la jeringa, y arrastrando en su desplazamiento a un elemento (4) asociado, a su extremo distal, conformado a modo de cubilete, que incorpora por la cara interna de su base (7) un cuerpo semi-ovoidal constituido por secciones (11) susceptibles de aproximación mutua por recuperación elástica y posicionables contra la aguja para evitar el retroceso del cubilete (4). La liberación del mecanismo se produce en virtud del empuje ejercido por pasadores (9), accionados desde el interior por una pieza (10) cónica, sobre proyecciones (2) asociadas a porciones elásticas de pared interna de dicho cubilete (4) y utilizadas como medio de retención por apoyo contra una pieza (1) fija.The protective system of the invention, intended to prevent the reuse of the syringes, of automatic actuation, includes an element (8) extendable by way of bellows, by virtue of its spring recovery, enclosing the needle (8) ) hypodermic syringe, and dragging in its displacement to an element (4) associated, to its distal end, shaped like a beaker, which incorporates a semi-ovoidal body constituted by sections on the inside of its base (7) (11) susceptible to mutual approximation by elastic recovery and positioned against the needle to avoid recoil of the beaker (4). The release of the mechanism occurs by virtue of the thrust exerted by pins (9), actuated from the inside by a conical piece (10), on projections (2) associated with elastic portions of the inner wall of said beaker (4) and used as retention means for support against a fixed part (1).
