## Description

The Graseby MS 26 is a portable syringe driver designed for continuous, fixed-rate infusion delivery over a 24-hour cycle. It accommodates syringes from 2 to 50 mL (user-selected) and delivers the loaded volume evenly across the 24-hour period. The pump is controlled by a simple mechanical drive with no digital display; an LED indicator shows pump status and alarms. Power is supplied by a single 9V alkaline battery, providing approximately 3–5 days of continuous operation.

The MS 26 is commonly used in ambulatory and home-care settings where steady, background infusion is required without frequent rate adjustments. It features audible and visual alarms for occlusion, end-of-infusion, and low battery.
