摘要：
1. The syringe plunger is formed from a polymeric material comprising: a pressure member positioned at the proximal end idistalny end bifurcated into a first tab of the plunger having a first tapered surface and the second tapered surface and the second tab of the plunger having a first conical surface and a second conical surface, wherein the distal end comprises: a first contact surface, a predetermined first conical surface of the first plunger foot and a first conical surface of the second legs of the plunger, wherein the first contact surface adapted to be the initial contact with the shutter mechanism of the inclusion, and the first to ntaktnaya surface is disposed at a first angle in the range of from about 40 ° to about 80 ° relative to the longitudinal axis of the syringe plunger, and a second contact surface, a predetermined second conical surface of the first foot of the plunger and a second conical surface of the second legs of the plunger, the second contact surface arranged to contact switching mechanism descent after its contact with the first contact poverhnostyu.2. The plunger of the syringe according to claim 1, wherein switching the shutter mechanism is configured to engage the first and second legs of the contact surfaces of the plunger, the switching mechanism drives the shutter syringe plunger when switching the shutter mechanism actuated minimal force ranging from about 5 N to about 25 H.3. The plunger of the syringe according to claim 2, wherein when driven syringe plunger pressing member syringe plunger pressurizes the substance in the sleeve shpri
