Claim 9:
10. A method for injecting a fluid, comprising:
providing a syringe assembly, the syringe assembly comprising
a syringe body having proximal and distal ends, a syringe interior, a distal needle interface at the distal end thereof, and a syringe flange at the proximal end thereof,
an injectable fluid disposed in the syringe interior,
a stopper member disposed in the syringe interior,
a plunger member coupled to the stopper member,
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, and
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 being in an aligned configuration wherein a longitudinal axis of the swing spacer is aligned with a longitudinal axis of the syringe body;

moving the swing spacer from the aligned configuration to an askew configuration wherein the longitudinal axis of the swing spacer is askew from the longitudinal axis of the syringe body;
applying a distally directed force to a proximal end of the plunger member to expel a portion of the injectable fluid from the syringe interior through the distal needle interface.
