SYRINGE PLUNGER DRIVER SYSTEM AND METHOD

摘要

A syringe plunger driver system capable of engaging different sized syringes. A drive head includes a pushing surface as well as spaced-apart arms biased toward each other and toward the pushing surface. An activating lever moved to a first position moves the arms outward away from each other and forward toward the syringe barrel of ease in loading a syringe. Moving the lever to a second position permits the biasing devices connected to the arms to move the arms inward to capture the syringe plunger and then rearward to hold the plunger flange against the pushing surface to resist siphoning.
