Baxter (Autosyringe) Syringe Pumps

Autosyringe Pumps, now manufactured by Baxter, are ambulatory syringe pumps with detachable pole clamps, housed in plastic water-resistant cases. They use digital input with LCD displays and include an AC charger for the recharge of the internal NiCad battery and an adapter for use with small syringes (1-3 ml). The family of Autosyringe pumps includes the AS20S, for continuous delivery, AS20A (similar to AS20S but includes intermittent program capability), and the AS20GH-2, which can be programmed in mcg/kg/minute or mcg/minute, eliminating the need for conversion tables; the AS20GH-2 is also capable of delivering a programmed bolus dose; it only accepts 60 ml syringes. Also available from Baxter is the AS40 series of pumps, an updated version of the AS20 series, and the AS50A, which replaces the AS40A.

Baxter AS40A Syringe Pumps

The AS40A has advanced programming capability, including variable occlusion sensitivity, automatic syringe size recognition, a Drug Library option with drug-specific infusion parameters stored in memory, and keypad lock. It can deliver continuously or can deliver a timed infusion of one or more equal doses according to a programmed schedule. It can program in ml/hr, units/hr, mg/minute, or m g/kg/minute with varying concentrations in mg/ml.

The AS40A has an LCD readout which displays the syringe manufacturer and size, the infusion rate, overbody weight, concentration, next dose, total volume limit and total volume delivered. Both the AS20 and AS40 series are rated at ± 3 % accuracy, not including syringe tolerance. All pumps can also be piggy-backed into an ongoing IV line to automatically deliver secondary medications.
