Abstract

La presente invención proporciona un dispositivo antiretroceso para una jeringa hipodérmica, que impide que la tuerca se mueva a lo largo del vástago de pistón roscado, al final del ajuste de la dosis, haciéndola girar en la dirección opuesta ala dirección en la cual la tuerca se mueve hasta la posición de ajuste de la nueva dosis, haciendo girar el botón de ajuste de dosis. De esta manera se obtiene que el movimiento de la tuerca a lo largo del vástago de pistón roscado se debe a la rotación del botón de ajuste de dosis en la dirección apropiada. El dispositivo preferido es una uñeta montada en la extremidad de un brazo flexible de la tuerca que coopera con unas ranuras formadas en el interior del cuerpo cilíndrico de la jeringa. La tuerca tiene también una superficie inclinada situada en la extremidad´que se adapta con una superficie inclinada situada en el cuerpo cilíndrico y la adaptación de estas superficies al final del ajuste de la dosis, empuja la uñeta en una ranura e impide la rotación de la tuerca equivocada.
