The invention relates to an injector device for syringes, which enables the syringe plunger to be moved gradually with little effort on the part of the patient or a third person. The invention comprises: a first support (5) which is equipped with a cavity (6) in which the barrel of the syringe (1) is inserted perpendicularly to the first support (5), the flanges (2) of the syringe resting on the peripheral edge of the cavity (6); and a second central support (9) on which the syringe plunger (3) rests. The aforementioned second support (9) is guided manually along parallel guides (8) that extend from the first support (5), between said first support (5) and the ends of the parallel guides (8), such as to push the plunger (3) inside the cylindrical barrel (1).

Le dispositif de l'invention facilite le déplacement progressif du piston de la seringue avec peu d'effort pour le patient ou pour une tierce personne. Il comprend un premier support (5) doté d'un creux (6) dans lequel se place, dans une disposition perpendiculaire audit premier support (5), le corps de la seringue (1) lequel s'appuie à l'aide de ses ailettes (2) sur le bord périmétrique dudit creux (6) et un second support (9) contre lequel appuie le piston (3) de la seringue. Ce second support (9) se déplace guidé par l'action manuelle exercée sur des guides (8) parallèles lesquels partent du premier support (5), entre ledit premier support (5) et les extrémités terminales desdits guides parallèles (8) poussant le piston (3) à l'intérieur du corps cylindrique (1).
