Abstract
A female syringe barrel is disclosed, which includes two protrusions provided on a cylindrical portion. A length (Lp) of each protrusion of the two protrusions along a direction, perpendicular to an axis of the cylindrical portion and perpendicular to a direction in which each protrusion of the two protrusions protrudes from the cylindrical portion, is 2.0 mm to 4.5 mm. A width of each protrusion of the two protrusions along an axial direction of the cylindrical portion is 1.0 mm to 2.1 mm. Each protrusion of the two protrusions has an inclined surface, which opposes a trailing flank of a screw when the two protrusions are engaged into the screw of a lock adapter, in an end portion close to a barrel body.
