This design relates to a disposable syringe assembly with possibly small-sized finger grip, while any part of the syringe is applicable for injection and medicaments are pre-filled for quick use. In particular, the device of this design relates to a disposable syringe assembly, comprising: plunger (40) having an oval shape at the front end and plunger tip (41) at the terminal end; plunger rod (50) having a disc (53) at the end of a screw (51) combined with a plunger tip (41) of said plunger (40); glass tube (10) where one side is clogged by the plunger (40), the other side is sealed by a rubber seal (21) and aluminum cap (25), and its outer diameter coincides with that of projection (17a) clogged by said plunger (40); finger grip (30) having a groove (33) to insert the projection (17a) of said glass tube (10) and a ring (31) as well; needle hub (60) having the inserted part sealed by a rubber seal (21) and aluminum cap (25) into said glass tube (10) as well as a needle hub mount (63) to hold two annular projections (67a, 67b) and needle (71) within an internal diameter; needle shield (73) being attached to a needle mount (63) of said needle hub (60). Since the finger grip has also a hexagonal shape, the device of this design has several advantages in that a) any part of syringe grip may be applicable prior to use, b) by preventing the displacement of a plunger before or after use, the discharge of contents during use or storage may be prevented, and c) the device cannot be refilled after use. Further, the device of this design is very useful in achieving the innate object of a disposable syringe assembly by solving the full administration of pharmaceuticals. Further, by detachedly mounting the rubber seal and aluminum cap, the device of this design can effectively prevent the mixing of aluminum particles into the medicaments.
