摘要：
Pistons for a syringe and syringe systems are disclosed. The pistons may include a base with a first end, a second end opposite the first end, and a side portion extending between the first end and the second end. The piston may also include at least one engagement portion extending around the circumference of the side portion of the base. Another embodiment of the plunger head may include a proximal end, a distal end opposite the proximal end, and an intermediate portion connecting the proximal end and the distal end. The intermediate portion is tapered from the proximal end to the distal end. The syringe system includes a piston and a plunger rod. The plunger rod may include a first end and a second end with the first end pressingly contacting the distal end of the piston.
