A dispensing syringe (10) has a barrel (20) keyed (31, 32) to a gripping assembly (40) having complementary keyed surfaces (42). A nut having dual threads (61, 62) of differing diameters is threaded to one end of the barrel (20) and receives a matingly threaded (71) plunger (70). Turning the plunger (70) causes it to advance within the barrel (20) due to the interaction of the mating threads (62, 71). The gripping assembly (40) is provided with winged projections (50) that facilitate handling and manipulation of the syringe (10). The complementary keyed surfaces (31,32 and 42) physically interact so as to prevent the gripping assembly (40) from turning or twisting about the barrel (20) during use.
L'invention concerne une seringue distributrice (10) comportant un corps (20) en prise (31, 32) avec un ensemble fixation (40) comportant des surfaces (42) d'assemblage complémentaires. Un écrou à deux filetages (61, 62) de diamètres différents est vissé sur une extrémité du corps (20) et reçoit un piston (70) doté d'un filetage (71) d'accouplement. Le piston (70) avance par rotation dans le corps (20) grâce à l'interaction des filetages d'accouplement (62, 71). L'ensemble fixation (40) comprend des ailettes en saillie (50) qui facilitent la manipulation de la seringue (10). Les surfaces d'assemblage complémentaires (31, 32 et 42) sont en interaction physique pour empêcher l'ensemble fixation (40) de tourner ou de se tordre autour du corps (20) de la seringue pendant son utilisation.
