Graseby MS 16A

The Graseby MS 16A is a portable syringe driver designed for continuous infusion at adjustable rates. It accepts syringes from 2 to 50 mL and uses an external rate dial to set delivery rate based on syringe size. The pump is powered by a single 9V alkaline battery and housed in durable plastic casing suitable for transport or bedside use. The MS 16A has no display screen; operation is guided by an LED indicator light. The pump signals occlusion, end of infusion, and low battery conditions via audible alarms. Typical battery life is 3–5 days depending on infusion rate and usage patterns.
