摘要：
A syringe assembly (10), comprising: a barrel of the syringe (20) having an inner surface (24) defining a chamber (25), an open proximal end (23), a distal end (21), and an outlet (11) disposed adjacent the distal end (21) in fluid communication with the chamber (25)； a piston assembly (30) disposed at least partially within the barrel of the syringe (20), comprising an elongated piston rod (31) having a proximal end (311), a distal end (312), a flange lock (34) formed therein between the proximal and distal ends (311, 312), and a piston head (40), the piston rod (31) is attachable with the piston head (40) in such a way that the piston rod (31) is adapted to move the piston head (40) into the chamber (25) of the syringe barrel (20) through an injection cycle； and a flange lock (26) disposed at the open proximal end (23) of the barrel (20), in which the flange lock (26) is integral with the open proximal end (23) of the syringe barrel (20 ), and in which during the injection cycle, the flange lock (26) is coupled to the locking flange (34) of the piston rod (31) in order to prevent the removal of the piston rod (31) from the barrel of the syringe (20), characterized in that, the piston rod (31) has a cylindrical shape defining a cylindrical outer surface (39) extending from the distal end (312) of the piston rod to the proximal end (311) of the piston rod and the locking flange (34) is formed on the outer surface of the piston rod, the flange lock (26) is coupled to the locking flange (34) of the piston rod ( 31) in order to retain the piston head (40) at or near a bottom position adjacent to the end distal (21) of the syringe barrel (20), and the flange lock (26) is configured to slidably engage the cylindrical outer surface (39) of the piston rod (31) during the injection cycle before coupling the locking flange (34) of the piston rod.Un montaje de jeringa (10), que comprende: un barril de la jeringa (20) que tiene una superficie interior (24) que define una cámar
