摘要：
A system includes a syringe barrel, a syringe plunger, and an annular collar. The syringe barrel has a longitudinal axis aligned axially between a discharge end and a cylinder end. The syringe plunger has a cap disposed on a first end, a piston disposed on a second end and configured for disposition in a bore of the barrel, and has a body disposed between the first end and the second end. The body has an external thread on a first surface and the body has a visible calibration indication aligned axially. The annular collar has at least one interrupted internal thread segment on an interior surface. The collar has elasticity such that in a first state, the internal thread is configured to engage the external thread and in a second state, in which a compressive force is exerted on opposing sides of the collar, the internal thread is disengaged from the external thread.
