The Atlanta Biomedical Corporation (ABC) 4100 is a compact, metal-housed syringe infusion pump purpose-built for anesthesia and OR environments. Unlike plastic-body competitors, the ABC 4100 uses an all-metal housing for superior durability, improved EMI immunity, and easier cleaning — making it well suited for the demanding conditions of an operating room.

The OR-Infusor version of the 4100 supports body-weight dosing (mcg/kg/min, mg/kg/hr), mass and unit modes, continuous ml/hr, volume-over-time, auto volume-over-time, and bolus — all with automatic syringe size recognition across BD, Monoject, Terumo, BD Glass, and ABC 140 ml syringes. Ninety customizable drug settings allow drug names and programmed parameters to be saved and retrieved. Flow rates scale automatically to the loaded syringe size, from 0.01 ml/h with a 1 ml syringe up to 1,500 ml/h with a 50/60 ml syringe. The pump operates on AC or an externally removable rechargeable battery pack providing approximately 12 hours of runtime at 5 ml/h.
