| abstract |
In some aspects, a vial spiking device includes a base, a spike extending from the base, and a side wall extending from the base and substantially surrounding the spike. The base and the side wall partially define a recess to receive a portion of a vial. Resilient fingers extend inwardly from the side wall into the recess. The fingers are spaced circumferentially around the side wall and are configured so that as the vial is inserted into the recess, the fingers deflect toward the side wall and allow the portion of the vial to move beyond the fingers. The fingers rebound into the recess after the portion of the vial has moved beyond the fingers. The side wall forces the portion of the vial away from the base and into contact with the fingers after the fingers have rebounded into the recess. |
