A mains electricity (AC-powered) device used to control and monitor the gravity infusion of intravenous (IV) fluids, providing an alarm (visible/audible) when pre-set limits are exceeded. It is available in two main configurations: 1) a device with an electronic flow sensor (drop counter) that monitors/measures the amount of fluid that passes through the infusion line; or 2) a device that measures the weight of the fluid container and may assist in bolus administration. The predetermined values may be selected by the user, and the device may display flow rate, total volume, and may record data. Some types can be used during arthroscopic procedures.
