A backstop for a syringe can include a base having a first surface and an opposing second surface. A skirt can extend outwardly from the second surface of the base. An opening can extend through the base. The opening can be surrounded by the skirt. A first extension can extend generally perpendicularly from the second surface at an outer periphery of the base. A second extension can extend generally perpendicularly from the second surface at the outer periphery of the base. The second extension can be diametrically opposed to the first extension.
