Patent attributes
A system for injecting includes a syringe body, a syringe interior, a syringe flange, and a stopper member and an injectable fluid disposed in the syringe interior. The system also includes a plunger member coupled to the stopper member. The system further includes a finger flange removably coupled to the syringe flange, the finger flange defining a pair of side openings and a pair of bumps adjacent respective side openings. Moreover, the system also includes a swing spacer rotatably coupled to the finger flange, the swing spacer defining a pair of arms, a pair of pivot pins, two pairs of slots, and a pair of indentations. The swing spacer is configured to define a distance of movement of the plunger member relative to the syringe body along a longitudinal axis of the syringe body, thereby defining a dose of the injectable fluid.
